A total of 15 participants participated in individual interviews and focus group discussions about the relationships among domestic political polarization, vaccine hesitancy, and behavioral responses to the COVID-19 pandemic. Political affiliation affected an individual’s decision on the COVID-19 vaccination, such that people who identified as Liberals and Democrats were more accepting of the vaccine. On the other hand, the level of influence declined over time (2020-2022) when the general conception of COVID-19 immunization shifted from political to personal. Results provided qualitative support to the previously identified positive relationship between divided political opinions and COVID-19 vaccine hesitancy and highlighted the decreasing trend in the power of political polarization in vaccination and the existence of other factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine%20hesitancy" title=" vaccine hesitancy"> vaccine hesitancy</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20polarization" title=" political polarization"> political polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=partisanship" title=" partisanship"> partisanship</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology" title=" ideology"> ideology</a> </p> <a href="https://publications.waset.org/abstracts/165405/the-impact-of-political-polarization-on-the-covid-19-vaccine-hesitancy-in-the-united-states-a-qualitative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165405.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2883</span> Estimating the Relationship between Education and Political Polarization over Immigration across Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ben%20Tappin">Ben Tappin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20McKay"> Ryan McKay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The political left and right appear to disagree not only over questions of value but, also, over questions of fact—over what is true “out there” in society and the world. Alarmingly, a large body of survey data collected during the past decade suggests that this disagreement tends to be greatest among the most educated and most cognitively sophisticated opposing partisans. In other words, the data show that these individuals display the widest political polarization in their reported factual beliefs. Explanations of this polarization pattern draw heavily on cultural and political factors; yet, the large majority of the evidence originates from one cultural and political context—the United States, a country with a rather unique cultural and political history. One consequence is that widening political polarization conditional on education and cognitive sophistication may be due to idiosyncratic cultural, political or historical factors endogenous to US society—rather than a more general, international phenomenon. We examined widening political polarization conditional on education across Europe, over a topic that is culturally and politically contested; immigration. To do so, we analyzed data from the European Social Survey, a premier survey of countries in and around the European area conducted biennially since 2002. Our main results are threefold. First, we see widening political polarization conditional on education over beliefs about the economic impact of immigration. The foremost countries showing this pattern are the most influential in Europe: Germany and France. However, we also see heterogeneity across countries, with some—such as Belgium—showing no evidence of such polarization. Second, we find that widening political polarization conditional on education is a product of sorting. That is, highly educated partisans exhibit stronger within-group consensus in their beliefs about immigration—the data do not support the view that the more educated partisans are more polarized simply because the less educated fail to adopt a position on the question. Third, and finally, we find some evidence that shocks to the political climate of countries in the European area—for example, the “refugee crisis” of summer 2015—were associated with a subsequent increase in political polarization over immigration conditional on education. The largest increase was observed in Germany, which was at the centre of the so-called refugee crisis in 2015. These results reveal numerous insights: they show that widening political polarization conditional on education is not restricted to the US or native English-speaking culture; that such polarization emerges in the domain of immigration; that it is a product of within-group consensus among the more educated; and, finally, that exogenous shocks to the political climate may be associated with subsequent increases in political polarization conditional on education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beliefs" title="beliefs">beliefs</a>, <a href="https://publications.waset.org/abstracts/search?q=Europe" title=" Europe"> Europe</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20polarization" title=" political polarization"> political polarization</a> </p> <a href="https://publications.waset.org/abstracts/105430/estimating-the-relationship-between-education-and-political-polarization-over-immigration-across-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105430.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2882</span> Political Polarization May Be Distorted When It Comes to Police Reform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Bartekian">Nancy Bartekian</a>, <a href="https://publications.waset.org/abstracts/search?q=Christine%20Reyna"> Christine Reyna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Republicans and Democrats are often polarized when it comes to important topics, but the portrayal of polarization of key issues might be distorted and exaggerated. We examined Republicans' and Democrats’ attitudes about police reform policy during the 2020 racial justice protests and calls to ‘defund the police’. We hypothesized that a) Republicans and Democrats will be polarized on the “defund police'' question; however, b) they will have similar overall attitudes towards specific police reform policies (will be on the same side of the scale--disagree vs. agree), but c) will differ in their extent of agreement or disagreement (main effect of political party ID, but located on the same side of the scale). Using one-way, Multivariate analysis of covariance (MANCOVA) controlling for race, education, and income, we found an overall effect of political party ID. Six out of the nine policies studied were, in fact, not polarizing; both groups were in consensus on whether they disagreed or agreed with the policy, including “defund police''. Results suggest that polarization might be exaggerated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20psychology" title="political psychology">political psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology" title=" ideology"> ideology</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a> </p> <a href="https://publications.waset.org/abstracts/150889/political-polarization-may-be-distorted-when-it-comes-to-police-reform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150889.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2881</span> A Reconfigurable Microstrip Patch Antenna with Polyphase Filter for Polarization Diversity and Cross Polarization Filtering Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakhdar%20Zaid">Lakhdar Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Albane%20Sangiovanni"> Albane Sangiovanni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A reconfigurable microstrip patch antenna with polyphase filter for polarization diversity and cross polarization filtering operation is presented in this paper. In our approach, a polyphase filter is used to obtain the four 90° phase shift outputs to feed a square microstrip patch antenna. The antenna can be switched between four states of polarization in transmission as well as in receiving mode. Switches are interconnected with the polyphase filter network to produce left-hand circular polarization, right-hand circular polarization, horizontal linear polarization, and vertical linear polarization. Additional advantage of using polyphase filter is its filtering capability for cross polarization filtering in right-hand circular polarization and left-hand circular polarization operation. The theoretical and simulated results demonstrated that polyphase filter is a good candidate to drive microstrip patch antenna to accomplish polarization diversity and cross polarization filtering operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20antenna" title="active antenna">active antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization%20diversity" title=" polarization diversity"> polarization diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20antenna" title=" patch antenna"> patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphase%20filter" title=" polyphase filter"> polyphase filter</a> </p> <a href="https://publications.waset.org/abstracts/59013/a-reconfigurable-microstrip-patch-antenna-with-polyphase-filter-for-polarization-diversity-and-cross-polarization-filtering-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59013.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2880</span> Future of E-Democracy in Polarized Politics and Role of Government with Perspective of E-Leadership in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kousar%20Shaheen">Kousar Shaheen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electoral process of Pakistan always remains underestimated due to malpractices claimed by the political leaders. The democratic system relies on public decision, selectorial process, transparent arrangements made by public administration, and governance system. Political polarization plays a vital role in any democratic system, which depends upon the way of applying leadership capabilities. In modern societies, public engagement is playing a key role in changing political polarization and implementation of the newest technologies, e-leadership and e-governance to bring e-democracy. The Overseas Pakistanis are unable to cast their votes in the selectorial process of Pakistan. To align this issue with civil society, efforts were made to implement modernized services and facilities by intervening in the Supreme Court. However, the results were found insignificant because of ineffective citizen engagement, IT-based, governance and public administration. which proved that the shifting to advanced society is crucial in Pakistan due to the elected Officials of current democratic system. It is an empirical study to involve Pakistani nationals (overseas) in the democratic process by utilizing the digital facility of vote casting. The role of Government. The role of e-leadership in changing the political polarization for the implementation of e-election will be measured by collecting data from different sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-democracy" title="e-democracy">e-democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=e-leadership" title=" e-leadership"> e-leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20polarization" title=" political polarization"> political polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20engagement" title=" public engagement"> public engagement</a> </p> <a href="https://publications.waset.org/abstracts/185667/future-of-e-democracy-in-polarized-politics-and-role-of-government-with-perspective-of-e-leadership-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">39</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2879</span> Rethinking the Public Sphere: Group Polarization on Social Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tianji%20Jiang">Tianji Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Habermas' definition of public sphere is a classical and well-regarded theory of the formation of public opinions, laying the foundation for many researches on public opinions and public media.

However, despite its fundamental and practical importance, in high school, this property of light is often neglected. This is a pity not only for its conceptual relevance, but also because polarization gives the possibility to perform many brilliant experiments with low cost materials. Moreover, the treatment of this matter lends very well to an interdisciplinary approach between art, biology and technology, which usually makes things more interesting to students. For these reasons, we have developed, and in this work, we introduce a laboratory on light polarization for high school and undergraduate students. They can see beautiful pictures when birefringent materials are set between two crossed polarizing filters. Pupils are very fascinated and drawn into by what they observe.

The antenna consists of a square patch with coplanar feed on the ground plane. On the patch side, there is a parasitic square ring that is responsible for changing the antenna polarization. On the ground plane, there is a rectangular slot. By changing of length of this slot, the antenna resonance frequency can be changed. The antenna operates at 1.57 and 2.45 GHz that used in GPS and Bluetooth applications, respectively. The length of the slot in the proposed antenna is 40 mm, and the antenna operates at the lower frequency (1.57 GHz). By using switches in the ground plane the slot length can be adjust to 24 mm, so the antenna operates at upper frequency (2.45 GHz). Two switches are mounted on the parasitic ring at optimized positions. By switching between the different states of these two switches, the proposed antenna operates with linear polarization (LP) and circular polarization (CP) at each operating frequency. The antenna gain at 1.57 and 2.45 GHz are 5.9 and 7.64 dBi, respectively. The antenna is analyzed using the CST Microwave Studio. The proposed antenna was fabricated and measured. Results comparison shows good agreement. The antenna has applications in several wireless communication systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microstrip%20patch%20antenna" title="microstrip patch antenna">microstrip patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable%20antenna" title=" reconfigurable antenna"> reconfigurable antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20reconfigurability" title=" frequency reconfigurability"> frequency reconfigurability</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization%20reconfigurability" title=" polarization reconfigurability"> polarization reconfigurability</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20square%20ring" title=" parasitic square ring"> parasitic square ring</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20polarization" title=" linear polarization"> linear polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20polarization" title=" circular polarization "> circular polarization </a> </p> <a href="https://publications.waset.org/abstracts/5893/dual-reconfigurable-antenna-using-capacitive-coupling-slot-and-parasitic-square-ring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5893.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">533</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2874</span> The Political Philosophy of Sikhism as a Resistance to Autocratic Regimes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vishavjeet%20Singh%20Goraya">Vishavjeet Singh Goraya</a>, <a href="https://publications.waset.org/abstracts/search?q=Bashir%20Ahmed%20Dar"> Bashir Ahmed Dar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sikhism is one of the youngest religions which came into existence only 550 years ago with Guru Nanak Dev. Guru Nanak and his successors not only gave religious sermons but also made bold commentaries on the politico-social situations of their times. Sikhism has consistently stood against autocratic regimes and societal polarization. The Sikh Gurus envisioned a political system based on equality, brotherhood, freedom of conscience, justice, and secularism where there was no discrimination and human rights of all were protected. The Sikh Gurus visualized a society based on an amalgamation of politics and religion without compromising morality and resisting any form of oppression and tyranny. The fifth guru of the Sikhs, Guru Arjan Dev, compiled the verses of his predecessors and many other saints belonging to different religions and castes in the form of Adi Granth, highlighting the egalitarian and secular foundations of Sikhism. Later tenth guru, Guru Gobind Singh, gave a concrete shape to the concepts of the earlier gurus written in Adi Granth and created an openly political and sovereign community known as Khalsa Panth with a distinct identity. This paper will use the qualitative historical approach to highlight Sikhism’s enduring commitment to fight oppression and tyranny, and it also examines how Sikhism offers solutions to contemporary issues of authoritarianism and polarization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sikhism" title="sikhism">sikhism</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurus" title=" Gurus"> Gurus</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20thought" title=" political thought"> political thought</a>, <a href="https://publications.waset.org/abstracts/search?q=equality" title=" equality"> equality</a>, <a href="https://publications.waset.org/abstracts/search?q=scriptures" title=" scriptures"> scriptures</a> </p> <a href="https://publications.waset.org/abstracts/193103/the-political-philosophy-of-sikhism-as-a-resistance-to-autocratic-regimes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193103.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">13</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2873</span> Law as a Means to Address Conflict</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tim%20Bakken">Tim Bakken</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper will discuss to what extent political polarization contributes to censorship, lack of civil discourse, and even violence. Most researchers have been unable to identify precisely what factors or processes contribute significantly to conflict. Absent such recognition, we have been unable to select effective remedies to address conflict. Through this paper, it will consider whether legal remedies can help to reduce conflict and polarization. My sense is that many current conflicts cannot be remedied primarily by law. But, there is little research on this hypothesis. Absent research and findings, nations may be looking to law for relief when, in fact, they should be looking at conditions underlying the formation of law or the absence of a more precise and effective legal remedy. It is hypothesized that the underlying reasons for conflict include sub-groups’ separation from the larger democratic society; misplaced loyalty to members of sub-groups; a culture of silence when recognizing wrongdoing; and retaliation against people who speak up. In sum, the greater distance citizens or institutions place between themselves and democratic norms, the more likely the members of a sub-group or institution will be to adopt conflict, even violence, as a method to obtain personal goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constitutional%20law" title="constitutional law">constitutional law</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20law" title=" criminal law"> criminal law</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a> </p> <a href="https://publications.waset.org/abstracts/174381/law-as-a-means-to-address-conflict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174381.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2872</span> Polarization Insensitive Absorber with Increased Bandwidth Using Multilayer Metamaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srilaxmi%20Gangula">Srilaxmi Gangula</a>, <a href="https://publications.waset.org/abstracts/search?q=MahaLakshmi%20Vinukonda"> MahaLakshmi Vinukonda</a>, <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20Rao"> Neeraj Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A wide band polarization insensitive metamaterial absorber with bandwidth enhancement in X and C band is proposed.

The decline of the longstanding ruling party, United Malays National Organization (UMNO), following the party rotation, has given rise to splinter parties such as the Indigenous Unity Party (Bersatu), along with the enduring presence of the Pan-Malaysian Islamic Party (PAS) in the northern region of the Malay Peninsula. However, the "Sheraton Move" in 2020 led to the fall of the Pakatan Harapan government and the emergence of Perikatan Nasional, signifying the ascent of a third political force. The 2022 general elections marked Malaysia's entry into a hung parliament, culminating in an intricate negotiation that resulted in a coalition government formed by Pakatan Harapan, Barisan Nasional, and the Sarawak parties alliance (GPS), collectively governing the Malaysian federal administration. During the 2023 state elections, Pakatan Harapan and Barisan Nasional formed an unprecedented alliance, yet the media framing benefited Perikatan Nasional, even securing substantial support from UMNO's traditional constituencies. In the era of converging new media, Malaysia’s democratization faces new challenges: first, political leaders leveraging media to cultivate unfiltered personas risk inducing populism; second, under the influence of agenda-setting and two-step flow theories, media contributes to polarization; lastly, Malaysia's multi-party system is no longer effectively moderate extreme ideologies into the political center. This study examines the role of media framing and its impact on the democratization process within Malaysia's consociational democracy under a multi-party system and analyzes media discourse before and after the 2023 Malaysian state elections to explore how different parties shape public opinion and political discourse, and how political messages may be amplified or distorted in the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-party%20system" title="multi-party system">multi-party system</a>, <a href="https://publications.waset.org/abstracts/search?q=democratization" title=" democratization"> democratization</a>, <a href="https://publications.waset.org/abstracts/search?q=elections" title=" elections"> elections</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20polarization" title=" political polarization"> political polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysia" title=" Malaysia"> Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20framing" title=" media framing"> media framing</a> </p> <a href="https://publications.waset.org/abstracts/171207/media-framing-and-democratization-under-multi-party-system-a-case-study-of-the-2023-malaysian-six-state-elections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2870</span> Mass Polarization in Three-Body System with Two Identical Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Filikhin">Igor Filikhin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20M.%20Suslov"> Vladimir M.

The term has to be taken into account for the analysis of AB- and AA-interactions based on experimental data for two- and three-body ground state energies. In this study, we present three-body calculations within the framework of a potential model for the kaonic clusters K−K−p and ppK−, nucleus 3H and hypernucleus 6 ΛΛHe. The systems are well clustering as A+ (A+B) with a ground state energy E2 for the pair A+B. The calculations are performed using the method of the Faddeev equations in configuration space. The phenomenological pair potentials were used. We show a correlation between the mass ratio mA/mB and the value δB of the mass-polarization term. For bosonic-like systems, this value is defined as δB = 2E2 − E3, where E3 is three-body energy when VAA = 0. For the systems including three particles with spin(isospin), the models with average AB-potentials are used. In this case, the Faddeev equations become a scalar one like for the bosonic-like system αΛΛ. We show that the additional energy conected with the mass-polarization term can be decomposite to a sum of the two parts: exchenge related and reduced mass related. The state of the system can be described as the following: the particle A1 is bound within the A + B pair with the energy E2, and the second particle A2 is bound with the pair with the energy E3 − E2. Due to the identity of A particles, the particles A1 and A2 are interchangeable in the pair A + B. We shown that the mass polarization δB correlates with a type of AB potential using the system αΛΛ as an example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=three-body%20systems" title="three-body systems">three-body systems</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20polarization" title=" mass polarization"> mass polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=Faddeev%20equations" title=" Faddeev equations"> Faddeev equations</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20interactions" title=" nuclear interactions"> nuclear interactions</a> </p> <a href="https://publications.waset.org/abstracts/46186/mass-polarization-in-three-body-system-with-two-identical-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46186.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2869</span> The Polarization on Twitter and COVID-19 Vaccination in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giselda%20Cristina%20Ferreira">Giselda Cristina Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Alberto%20Kamienski"> Carlos Alberto Kamienski</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20L%C3%ADgia%20Scott"> Ana Lígia Scott</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 pandemic has enhanced the anti-vaccination movement in Brazil, supported by unscientific theories and false news and the possibility of wide communication through social networks such as Twitter, Facebook, and YouTube. The World Health Organization (WHO) classified the large volume of information on the subject against COVID-19 as an Infodemic. In this paper, we present a protocol to identify polarizing users (called polarizers) and study the profiles of Brazilian polarizers on Twitter (renamed to X some weeks ago). We analyzed polarizing interactions on Twitter (in Portuguese) to identify the main polarizers and how the conflicts they caused influenced the COVID-19 vaccination rate throughout the pandemic. This protocol uses data from this social network, graph theory, Java, and R-studio scripts to model and analyze the data. The information about the vaccination rate was obtained in a public database for the government called OpenDataSus. The results present the profiles of Twitter’s Polarizer (political position, gender, professional activity, immunization opinions). We observed that social and political events influenced the participation of these different profiles in conflicts and the vaccination rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Twitter" title="Twitter">Twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine" title=" vaccine"> vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil" title=" Brazil"> Brazil</a> </p> <a href="https://publications.waset.org/abstracts/171793/the-polarization-on-twitter-and-covid-19-vaccination-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2868</span> Mechanism of Dual Ferroic Properties Formation in Substituted M-Type Hexaferrites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20V.%20Trukhanov">A.

The configuration of the design consists of four double-fed circular-ring antenna elements located at different edges of the printed circuit board (PCB) with an FR-4 substrate and overall dimension of 75×150 mm<sup>2</sup>. The antenna elements are fed by 50-Ohm microstrip-lines and provide polarization and radiation pattern diversity function due to the orthogonal placement of their feed lines. A good impedance bandwidth (S<sub>11</sub> ≤ -10 dB) of 3.4-3.8 GHz has been obtained for the smartphone antenna array. However, for S<sub>11</sub> ≤ -6 dB, this value is 3.25-3.95 GHz. More than 3 dB realized gain and 80% total efficiency are achieved for the single-element radiator. The presented design not only provides the required radiation coverage but also generates the polarization diversity characteristic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellular%20communications" title="cellular communications">cellular communications</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple-input%2Fmultiple-output%20systems" title=" multiple-input/multiple-output systems"> multiple-input/multiple-output systems</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile-phone%20antenna" title=" mobile-phone antenna"> mobile-phone antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization%20diversity" title=" polarization diversity"> polarization diversity</a> </p> <a href="https://publications.waset.org/abstracts/111449/dual-polarized-multi-antenna-system-for-massive-mimo-cellular-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111449.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2865</span> Resolving Partisan Conflict: A Dialectical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20F.%20Mascolo">Michael F.

Western nations are losing the common agonistic ground needed to engage in traditional forms of democracy – adversarial debate, voting, and the peaceful transfer of power. Political polarization among party elites has become commonplace. Because it seeks to resolve conflict through the integration of opposites, a dialectical approach to resolving partisan conflict offers the promise of helping political partisans bridge ideological divides. This paper contains an analysis of dialectical engagement as a collaborative alternative to adversarial politics. Dialectical engagement involves two broad phases: collaborative political problem-solving and dialectical problem-solving. The paper contains a description of an 18-month longitudinal study assessing the effectiveness of dialectical engagement as a method for bridging divides on contentious socio-political issues. The study shows how dialectical engagement produced dramatic consensus among a small group of individuals from different political orientations as they worked together to resolve the issue of capital punishment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20democracy" title="collaborative democracy">collaborative democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=dialectical%20thinking" title=" dialectical thinking"> dialectical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20punishment" title=" capital punishment"> capital punishment</a>, <a href="https://publications.waset.org/abstracts/search?q=partisan%20conflict" title=" partisan conflict"> partisan conflict</a> </p> <a href="https://publications.waset.org/abstracts/164033/resolving-partisan-conflict-a-dialectical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2864</span> Pyroelectric Effect on Thermoelectricity of AlInN/GaN Heterostructures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20K.%20Sahoo">B. K. Sahoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Superior thermoelectric (TE) efficiency of AlₓIn₁₋ₓN /GaN heterostructure (HS) requires a minimum value of thermal conductivity (k). A smaller k would lead to even further increase of TE figure of merit (ZT). The built-in polarization (BIP) electric field of AlₓIn₁₋ₓN /GaN HS enhances S, and σ of the HS, however, the effect of BIP field on k of the HS has not been explored. Study of thermal conductivities (k: without BIP and kp: including BIP) vs temperature predicts pyroelectric behavior of HS. Both k and kp show crossover at a temperature Tp. The result shows that below Tp, kp < k due to negative thermal expansion coefficient (TEC). However, above Tp, kp > k. Above Tp, piezoelectric polarization dominates over spontaneous polarization due to positive TEC. This generates more lattice mismatch resulting in the significant contribution of BIP field to thermal conductivity. Thus, Tp can be considered as primary pyroelectric transition temperature of the material as above Tp thermal expansion takes place which is the reason for the secondary pyroelectric effect. It is found that below Tp, kp is decreased; thus enhancing TE efficiency. For x=0.1, 0.2 and 0.3; Tp are close to 200, 210 and 260 K, respectively. Thus, k of the HS can be modified as per requirement by tailoring the Al composition; making it suitable simultaneously for the design of high-temperature pyroelectric sensors and TE module for maximum power production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al%E2%82%93In%E2%82%81%E2%82%8B%E2%82%93N%2FGaN%20heterostructure" title="AlₓIn₁₋ₓN/GaN heterostructure">AlₓIn₁₋ₓN/GaN heterostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=built%20in%20polarization" title=" built in polarization"> built in polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=pyroelectric%20behavior" title=" pyroelectric behavior"> pyroelectric behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20efficiency" title=" thermoelectric efficiency"> thermoelectric efficiency</a> </p> <a href="https://publications.waset.org/abstracts/107402/pyroelectric-effect-on-thermoelectricity-of-alinngan-heterostructures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107402.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2863</span> Fact-checking and Political Polarization in an Emerging Democracy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Agyekum">Eric Agyekum</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominic%20Asitanga"> Dominic Asitanga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ghana is widely considered asa beacon of democracy in sub-Saharan Africa. With a relatively free media, the country was ranked30thin the world and third in Africaon the 2021 Press Freedom Index. Despite the democratic gains, itis one of the most politically polarized nations in the world. Ghana’spolitical division is evident in the current hunglegislature, where each of the two dominant political parties has 137 members, with an independent member occupying the remaining one seat. Misinformation and fake newsthrive in systems with acuteideological and political differences(Imelda et al, 2021; Azzimonti&Fernandes, 2018; Spohr, 2017) and Ghana is no exception. The information disorder problem has been exacerbatedby the COVID-19 pandemic, with its attendant conspiracy theories and speculations, making it difficult for the media and fact-checking organizations to verifyall claims and flag false information. In Ghana, fact-checking agencies like Ghana Fact, Dubawa Ghana, and some mainstream news media organizations have been fact-checking political claims, COVID-19 conspiracy theories, and many others. However, it is not clear if the audience consumeand attach prominence to these fact-checked stories or even visit the websites of the fact-checking agencies to read the content. Nekmat (2020) opine that though the literature on fact-checking suggest that fact-checked stories can alter readers’ beliefs, very few studies have investigated the patronage and the potential of fact-checks to deter users from sharing false news with others, particularly on social media. In response to Nekmat, this study has been initiated to examine the perception and attitude of the audience in Ghana towards fact-checks. Anchored on the principles of the nudge theory, this study will investigate how fact-checked stories alters readers’ behavioural patterns. A survey will be conducted to collect data from sampled members of the Ghanaian society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fact-checking" title="fact-checking">fact-checking</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20disorder" title=" information disorder"> information disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=nudge%20theory" title=" nudge theory"> nudge theory</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20polarization" title=" political polarization"> political polarization</a> </p> <a href="https://publications.waset.org/abstracts/147958/fact-checking-and-political-polarization-in-an-emerging-democracy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147958.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2862</span> Angiogenic and Immunomodulatory Properties and Phenotype of Mesenchymal Stromal Cells Can Be Regulated by Cytokine Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekaterina%20Zubkova">Ekaterina Zubkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Irina%20Beloglazova"> Irina Beloglazova</a>, <a href="https://publications.waset.org/abstracts/search?q=Iurii%20Stafeev"> Iurii Stafeev</a>, <a href="https://publications.waset.org/abstracts/search?q=Konsyantin%20Dergilev"> Konsyantin Dergilev</a>, <a href="https://publications.waset.org/abstracts/search?q=Yelena%20Parfyonova"> Yelena Parfyonova</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Menshikov"> Mikhail Menshikov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mesenchymal stromal cells from adipose tissue (MSC) currently are widely used in regenerative medicine to restore the function of damaged tissues, but that is significantly hampered by their heterogeneity. One of the modern approaches to overcoming this obstacle is the polarization of cell subpopulations into a specific phenotype under the influence of cytokines and other factors that activate receptors and signal transmission to cells. We polarized MSC with factors affecting the inflammatory signaling and functional properties of cells, followed by verification of their expression profile and ability to affect the polarization of macrophages. RT-PCR evaluation showed that cells treated with LPS, interleukin-17, tumor necrosis factor α (TNF α), primarily express pro-inflammatory factors and cytokines, and after treatment with polyninosin polycytidic acid and interleukin-4 (IL4) anti-inflammatory factors and some proinflammatory factors. MSC polarized with pro-inflammatory cytokines showed a more robust pro-angiogenic effect in fibrin gel bead 3D angiogenesis assay. Further, we evaluated the possibility of paracrine effects of MSCs on the polarization of intact macrophages. Polarization efficiency was assesed by expression of M1/M2 phenotype markers CD80 and CD206. We showed that conditioned media from MSC preincubated in the presence of IL-4 cause an increase in CD206 expression similar to that observed in M2 macrophages. Conditioned media from MSC polarized in the presence of LPS or TNF-α increased the expression of CD80 antigen in macrophages, similar to that observed in M1 macrophages. In other cases, a pronounced paracrine effect of MSC on the polarization of macrophages was not detected. Thus, our study showed that the polarization of MSC along the pro-inflammatory or anti-inflammatory pathway allows us to obtain cell subpopulations that have a multidirectional modulating effect on the polarization of macrophages.

In general, media helps to spread various ideas very fast, and it means that processes of polarization are best revealed in computer-mediated communication (CMC) contexts. For this reason, data for the research was collected from online texts about a current, very diverse topic in Lithuania - Lithuanian language policy and regulations, because this topic is causing a lot of tension in Lithuanian society. Computer-mediated communication allows users to edit their message before they send it. It means that addressees carefully select verbal expressions to convey their message. In other words, each impoliteness strategy and its verbal expression were created intentionally. Impoliteness strategies in this research are understood as various ways to reach a communicative goal: belittle the other. To reach the goal, the public opinions of various Lithuanian public figures (e. g., cultural people, politicians, officials) were collected from new portals in 2019–2023 and analyzed using both quantitative and qualitative approaches. First, problematic aspects of the language policy, for which public figures complain, were identified. Then instances when public figures take a defensive position were analyzed: how they express this position and what it reveals about Lithuanian culture. Findings of this research demonstrate how concepts of impoliteness theory can be applied in analyzing the process of polarization in Lithuanian society on issues related to the State language policy. Also, to reveal how polarization is constructed, these tasks were set: a) determine which impoliteness strategies are used throughout the process of creating polarization, b) analyze how they were expressed verbally (e. g., as an advice, offer, etc.). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impoliteness" title="impoliteness">impoliteness</a>, <a href="https://publications.waset.org/abstracts/search?q=Lithuanian%20language%20policy" title=" Lithuanian language policy"> Lithuanian language policy</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=impoliteness%20strategies" title=" impoliteness strategies"> impoliteness strategies</a> </p> <a href="https://publications.waset.org/abstracts/183376/polarization-of-lithuanian-society-on-issues-related-to-language-politics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183376.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">57</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2860</span> The Interplay between Autophagy and Macrophages' Polarization in Wound Healing: A Genetic Regulatory Network Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayada%20Mazher">Mayada Mazher</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Moustafa"> Ahmed Moustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdellatif"> Ahmed Abdellatif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Autophagy is a eukaryotic, highly conserved catabolic process implicated in many pathophysiologies such as wound healing. Autophagy-associated genes serve as a scaffolding platform for signal transduction of macrophage polarization during the inflammatory phase of wound healing and tissue repair process. In the current study, we report a model for the interplay between autophagy-associated genes and macrophages polarization associated genes. Methods: In silico analysis was performed on 249 autophagy-related genes retrieved from the public autophagy database and gene expression data retrieved from Gene Expression Omnibus (GEO); GSE81922 and GSE69607 microarray data macrophages polarization 199 DEGS. An integrated protein-protein interaction network was constructed for autophagy and macrophage gene sets. The gene sets were then used for GO terms pathway enrichment analysis. Common transcription factors for autophagy and macrophages' polarization were identified. Finally, microRNAs enriched in both autophagy and macrophages were predicated. Results: In silico prediction of common transcription factors in DEGs macrophages and autophagy gene sets revealed a new role for the transcription factors, HOMEZ, GABPA, ELK1 and REL, that commonly regulate macrophages associated genes: IL6,IL1M, IL1B, NOS1, SOC3 and autophagy-related genes: Atg12, Rictor, Rb1cc1, Gaparab1, Atg16l1. Conclusions: Autophagy and macrophages' polarization are interdependent cellular processes, and both autophagy-related proteins and macrophages' polarization related proteins coordinate in tissue remodelling via transcription factors and microRNAs regulatory network. The current work highlights a potential new role for transcription factors HOMEZ, GABPA, ELK1 and REL in wound healing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autophagy%20related%20proteins" title="autophagy related proteins">autophagy related proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20network%20analysis" title=" integrated network analysis"> integrated network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=macrophages%20polarization%20M1%20and%20M2" title=" macrophages polarization M1 and M2"> macrophages polarization M1 and M2</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20remodelling" title=" tissue remodelling"> tissue remodelling</a> </p> <a href="https://publications.waset.org/abstracts/108802/the-interplay-between-autophagy-and-macrophages-polarization-in-wound-healing-a-genetic-regulatory-network-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108802.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2859</span> Investigation of the Jupiter’s Galilean Moons</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Revaz%20Chigladze">Revaz Chigladze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the research is to investigate the surfaces of Jupiter's Galilean moons, namely which moon has the most uniform surface among them, what is the difference between the front (in the direction of motion) and the back sides of each moon's surface, as well as the temporal variations of the moons. Since 1981, the E. Kharadze National Astrophysical Observatory of Georgia has been conducting polarimetric (P) and photometric (M) observations of Jupiter's Galilean moons with telescopes of different diameters (40 cm and 125 cm) and the polarimeter ASEP-78 in combination with them and the latest generation photometer with a polarimeter and modern light receiver SBIG. As it turns out from the analysis of the observed material, the parameters P and M depend on α-the phase angle of the moon (satellite), L- the orbital latitude of the moon (satellite), λ- the wavelength, and t - the period of observation, i.e., P = P (α, L, λ , t), and similarly M = M (α, L, λ. , t). Based on the analysis of the observed material, the following was studied: Jupiter's Galilean moons: dependence of the magnitude and phase angle of the degree of linear polarization for different wavelengths; Dependence of the degree of polarization and the orbital longitude; dependence between the magnitude of the degree of polarization and the wavelength; time dependence of the degree of polarization and the dependence between photometric and polarimetric characteristics (including establishing correlation). From the analysis of the obtained results, we get: The magnitude of the degree of polarization of Jupiter's Galilean moons near the opposition significantly differs from zero. Europa appears to have the most uniform surface, and Callisto the least uniform. Time variations are most characteristic of Io, which confirms the presence of volcanic activity on its surface. Based on the observed material, it can be seen that the intensity of light reflected from the front hemisphere of the first three moons: Io, Europa, and Ganymede, is less than the intensity of light reflected from the rear hemisphere, and in the case of the Callisto it is the opposite. The paper provides a convincing (natural, real) explanation of this fact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Galilean%20moons" title="Galilean moons">Galilean moons</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20polarization" title=" degree of polarization"> degree of polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=photometry" title=" photometry"> photometry</a>, <a href="https://publications.waset.org/abstracts/search?q=front%20and%20rear%20hemispheres" title=" front and rear hemispheres"> front and rear hemispheres</a> </p> <a href="https://publications.waset.org/abstracts/162070/investigation-of-the-jupiters-galilean-moons" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162070.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2858</span> Effect of Sr-Doping on Multiferroic Properties of Ca₁₋ₓSrₓMn₇O₁₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parul%20Jain">Parul Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitendra%20Saha"> Jitendra Saha</a>, <a href="https://publications.waset.org/abstracts/search?q=L.%20C.%20Gupta"> L.

CaMn₇O₁₂ is a type-II multiferroic, wherein polarization is caused by magnetic spin ordering. In this report magnetic and ferroelectric properties of Ca₁₋ₓSrₓMn₇O₁₂ (0 ≤ x ≤ 0.1) are investigated. Samples were prepared by wet sol gel technique using their respective nitrates; powders thus obtained were calcined and sintered in optimized conditions. The X-ray diffraction patterns of all samples doped with Sr concentrations in the range (0 ≤ x ≤ 10%) were found to be free from secondary phases. Magnetization versus temperature and magnetization versus field measurements were carried out using Quantum Design SQUID magnetometer. Pyroelectric current measurements were done for finding the polarization in the samples. Findings of the measurements are: (i) increase of Sr-doping in CaMn₇O₁₂ lattice i.e. for x ≤ 0.02, increases the polarization, whereas decreases the magnetization and the coercivity of the samples; (ii) the material with x = 0.02 exhibits ferroelectric polarization Ps which is more than double the Ps in the un-doped material and the magnetization M is reduced to less than half of that of the pure material; remarkably (iii) the modifications in Ps and M are reversed as x increases beyond x = 0.02 and for x = 0.10, Ps is reduced even below that for the pure sample; (iv) there is no visible change of the two magnetic transitions TN1 (90 K) and TN2 (48 K) of the pure material as a function of x. The strong simultaneous variations of Ps and M for x = 0.02 strongly suggest that either a basic modification of the magnetic structure of the material or a significant change of the coupling of P and M or possibly both. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferroelectric" title="ferroelectric">ferroelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=isovalent" title=" isovalent"> isovalent</a>, <a href="https://publications.waset.org/abstracts/search?q=multiferroic" title=" multiferroic"> multiferroic</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=pyroelectric" title=" pyroelectric"> pyroelectric</a> </p> <a href="https://publications.waset.org/abstracts/52624/effect-of-sr-doping-on-multiferroic-properties-of-ca1srmn7o12" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52624.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2857</span> Bright–Dark Pulses in Nonlinear Polarisation Rotation Based Erbium-Doped Fiber Laser</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Z.%20R.%20R.%20Rosdin">R.

Bright–dark pulses could be achieved when the laser works in the passively mode-locking regime and the net group velocity dispersion is quite anomalous. The EDFL starts to generate a bright pulse train with degenerated dark pulse at the mode-locking threshold pump power of 35.09 mW by manipulating the polarization states of the laser oscillation modes using a polarization controller (PC). A split bright–dark pulse is generated when further increasing the pump power up to 37.95 mW. Stable bright pulses with no obvious evidence of a dark pulse can also be generated when further adjusting PC and increasing the pump power up to 52.19 mW. At higher pump power of 54.96 mW, a new form of bright-dark pulse emission was successfully identified with the repetition rate of 29 kHz. The bright and dark pulses have a duration of 795.5 ns and 640 ns, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erbium-doped%20fiber%20laser" title="Erbium-doped fiber laser">Erbium-doped fiber laser</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20polarization%20rotation" title=" nonlinear polarization rotation"> nonlinear polarization rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=bright-dark%20pulse" title=" bright-dark pulse"> bright-dark pulse</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic" title=" photonic"> photonic</a> </p> <a href="https://publications.waset.org/abstracts/19127/bright-dark-pulses-in-nonlinear-polarisation-rotation-based-erbium-doped-fiber-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19127.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2856</span> Polarization of Glass with Positive and Negative Charge Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valentina%20V.%20Zhurikhina">Valentina V.

The usage of the poling for second optical harmonic generation, fabrication of optical waveguides and electrooptic modulators was also reported. Nevertheless, the detailed description of the poling of glasses, containing multiple charge carriers is still under discussion. In particular, the role of possible migration of electrons in the space charge formation usually remains out of the question. In this work, we performed the numerical simulation of thermal poling of a silicate glass, containing Na, K, Mg, and Ca. We took into consideration the contribution of electrons in the polarization process. The possible explanation of migration of electrons can be the break of non-bridging oxygen bonds. It was found, that the modeled depth of the space charge region is about 10 times higher if the migration of the negative charges is taken under consideration. The simulated profiles of cations, participating in the polarization process, are in a good agreement with the experimental data, obtained by glow discharge spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20poling" title="glass poling">glass poling</a>, <a href="https://publications.waset.org/abstracts/search?q=charge%20transport" title=" charge transport"> charge transport</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration%20profiles" title=" concentration profiles"> concentration profiles</a> </p> <a href="https://publications.waset.org/abstracts/67507/polarization-of-glass-with-positive-and-negative-charge-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2855</span> Mueller Matrix Polarimetry for Analysis Scattering Biological Fluid Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Cherif">S.

It is in this last characteristic that we will be interested. The polarization of the light was introduced in order to describe the vectorial behavior of the light; it describes the way in which the electric field evolves in a point of space. Our work consists in studying diffusing mediums. Different types of biological fluids were selected to study the evolution of each with increasing scattering power of the medium, and in the same time to make a comparison between them. When crossing these mediums, the light undergoes modifications and/or deterioration of its initial state of polarization. This phenomenon is related to the properties of the medium, the idea is to compare the characteristics of the entering and outgoing light from the studied medium by a white light. The advantage of this model is that it is experimentally accessible workable intensity measurements with CCD sensors and allows operation in 2D. The latter information is used to discriminate some physical properties of the studied areas. We chose four types of milk to study the evolution of each with increasing scattering power of the medium. <p class="card-text"><strong>Keywords:</strong> <a
