RNAseq results obtained from polyA+ RNA selection protocol (POLYA) and from exonic regions capturing protocol (ACCESS) indicate that ACCESS detects 10% more coding SNV/INDELs with respect to POLYA. ACCESS requires less reads for coding SNV detection with respect to POLYA. However, if the analysis aims at identifying SNV/INDELs also in the 5’ and 3’ UTRs, POLYA is definitively the preferred method.

Notwithstanding this increase in research and conducted studies however, the adaption of SNS based modules have failed to proliferate within Universities. This paper, commences its contribution by analyzing the various models and theories proposed in literature and amalgamates together various effective aspects for the inclusion of social technology within e-Learning. A three phased framework is further proposed which details the necessary considerations for the successful adaptation of SNS in enhancing the students learning experience. This proposal outlines the theoretical foundations which will be analyzed in practical implementation across international university campuses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eLearning" title="eLearning">eLearning</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20network%20sites" title=" social network sites"> social network sites</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20learning" title=" student learning"> student learning</a> </p> <a href="https://publications.waset.org/abstracts/26573/the-use-of-social-networking-sites-in-elearning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26573.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">340</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">10</span> Nature-Based Solutions: An Intelligent Method to Enhance Urban Resilience in Response to Climate Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Calabrese">Mario Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Iandolo"> Francesca Iandolo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pietro%20Vito"> Pietro Vito</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaele%20D%27Amore"> Raffaele D'Amore</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Caputo"> Francesco Caputo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a synopsis of Nature-Based Solutions (NBS), a fresh and emerging concept in mitigating and adapting to climate change.

Besides it must be taken into account the amount of disposable material which may be needed together with the use of commercial software for their performing.

Currently, available information management systems are mainly focused on Record & Verify and clinical data, and only to a small extent on physical data. Thus, results in a partial and limited use of the actually available information. In the present work we describe the implementation at our department of a centralized information management system based on a web server. Our system manages both information generated during patient planning and treatment, and information of general interest for the whole department (i.e. treatment protocols, quality assurance protocols etc.). Our objective it to be able to analyze in a simple and efficient way all the available data and thus to obtain quantitative evaluations of our treatments. This would allow us to improve our work flow and protocols. To this end we have implemented a relational data base which would allow us to use in a practical and efficient way all the available information.

In particular, in recent years the use of machine learning algorithms in the field of e-commerce has spread worldwide. In this research study, a prototype software platform was designed and implemented in order to suggest to users the most suitable products for their needs. The platform includes a chatbot and a recommender system based on artificial intelligence algorithms that provide suggestions and decision support to the customer. The recommendation systems perform the important function of automatically filtering and personalizing information, thus allowing to manage with the IT overload to which the user is exposed on a daily basis. Recently, international research has experimented with the use of machine learning technologies with the aim to increase the potential of traditional recommendation systems. Specifically, support vector machine algorithms have been implemented combined with natural language processing techniques that allow the user to interact with the system, express their requests and receive suggestions. The interested user can access the web platform on the internet using a computer, tablet or mobile phone, register, provide the necessary information and view the products that the system deems them most appropriate. The platform also integrates a dashboard that allows the use of the various functions, which the platform is equipped with, in an intuitive and simple way. Artificial intelligence algorithms have been implemented and trained on historical data collected from user browsing. Finally, the testing phase allowed to validate the implemented model, which will be further tested by letting customers use it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=recommender%20system" title=" recommender system"> recommender system</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20platform" title=" software platform"> software platform</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/150813/design-and-implementation-of-a-software-platform-based-on-artificial-intelligence-for-product-recommendation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150813.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">134</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">6</span> On the Monitoring of Structures and Soils by Tromograph</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magar%C3%B2%20Floriana">Magarò Floriana</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinno%20Raffaele"> Zinno Raffaele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 2009, with the coming into force of the January 14, 2008 Ministerial Decree "New technical standards for construction", and the explanatory ministerial circular N°.617 of February 2, 2009, the question of seismic hazard and the design of seismic-resistant structures in Italy has acquired increasing importance. One of the most discussed aspects in recent Italian and international scientific literature concerns the dynamic interaction between land and structure, and the effects which dynamic coupling may have on individual buildings. In effect, from systems dynamics, it is well known that resonance can have catastrophic effects on a stimulated system, leading to a response that is not compatible with the previsions in the design phase. The method used in this study to estimate the frequency of oscillation of the structure is as follows: the analysis of HVSR (Horizontal to Vertical Spectral Ratio) relations. This allows for evaluation of very simple oscillation frequencies for land and structures. The tool used for data acquisition is an experimental digital tromograph. This is an engineered development of the experimental Languamply RE 4500 tromograph, equipped with an engineered amplification circuit and improved electronically using extremely small electronic components (size of each individual amplifier 16 x 26 mm). This tromograph is a modular system, completely "free" and "open", designed to interface Windows, Linux, OSX and Android with the outside world. It an amplifier designed to carry out microtremor measurements, yet which will also be useful for seismological and seismic measurements in general. The development of single amplifiers of small dimension allows for a very clean signal since being able to position it a few centimetres from the geophone eliminates cable “antenna” phenomena, which is a necessary characteristic in seeking to have signals which are clean at the very low voltages to be measured. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microtremor" title="microtremor">microtremor</a>, <a href="https://publications.waset.org/abstracts/search?q=HVSR" title=" HVSR"> HVSR</a>, <a href="https://publications.waset.org/abstracts/search?q=tromograph" title=" tromograph"> tromograph</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20engineering" title=" structural engineering"> structural engineering</a> </p> <a href="https://publications.waset.org/abstracts/22674/on-the-monitoring-of-structures-and-soils-by-tromograph" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22674.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">409</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">5</span> National Plans for Recovery and Resilience between National Recovery and EU Cohesion Objectives: Insights from European Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arbolino%20Roberta">Arbolino Roberta</a>, <a href="https://publications.waset.org/abstracts/search?q=Boffardi%20Raffaele"> Boffardi Raffaele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Achieving the highest effectiveness for the National Plans for Recovery and Resilience (NPRR) while strengthening the objectives of cohesion and reduction of intra-EU unbalances is only possible by means of strategic, coordinated, and coherent policy planning. Therefore, the present research aims at assessing and quantifying the potential impact of NPRRs across the twenty-seven European Member States in terms of economic convergence, considering disaggregated data on industrial, construction, and service sectors. The first step of the research involves a performance analysis of the main macroeconomic indicators describing the trends of twenty-seven EU economies before the pandemic outbreak. Subsequently, in order to define the potential effect of the resources allocated, we perform an impact analysis of previous similar EU investment policies, estimating national-level sectoral elasticity associated with the expenditure of the 2007-2013 and 2014-2020 Cohesion programmes funds. These coefficients are then exploited to construct adjustment scenarios. Finally, convergence analysis is performed on the data used for constructing scenarios in order to understand whether the expenditure of funds might be useful to foster economic convergence besides driving recovery. The results of our analysis show that the allocation of resources largely mirrors the aims of the policy framework underlying the NPRR, thus reporting the largest investments in both those sectors most affected by the economic shock (services) and those considered fundamental for the digital and green transition. Notwithstanding an overall positive effect, large differences exist among European countries, while no convergence process seems to be activated or fostered by these interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NPRR" title="NPRR">NPRR</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20evaluation" title=" policy evaluation"> policy evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesion%20policy" title=" cohesion policy"> cohesion policy</a>, <a href="https://publications.waset.org/abstracts/search?q=scenario%20Nalsysi" title=" scenario Nalsysi"> scenario Nalsysi</a> </p> <a href="https://publications.waset.org/abstracts/159035/national-plans-for-recovery-and-resilience-between-national-recovery-and-eu-cohesion-objectives-insights-from-european-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159035.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">83</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">4</span> Heterogeneous-Resolution and Multi-Source Terrain Builder for CesiumJS WebGL Virtual Globe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umberto%20Di%20Staso">Umberto Di Staso</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Soave"> Marco Soave</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessio%20Giori"> Alessio Giori</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20Prandi"> Federico Prandi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaele%20De%20Amicis"> Raffaele De Amicis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing availability of information about earth surface elevation (Digital Elevation Models DEM) generated from different sources (remote sensing, Aerial Images, Lidar) poses the question about how to integrate and make available to the most than possible audience this huge amount of data. In order to exploit the potential of 3D elevation representation the quality of data management plays a fundamental role. Due to the high acquisition costs and the huge amount of generated data, highresolution terrain surveys tend to be small or medium sized and available on limited portion of earth. Here comes the need to merge large-scale height maps that typically are made available for free at worldwide level, with very specific high resolute datasets. One the other hand, the third dimension increases the user experience and the data representation quality, unlocking new possibilities in data analysis for civil protection, real estate, urban planning, environment monitoring, etc. The open-source 3D virtual globes, which are trending topics in Geovisual Analytics, aim at improving the visualization of geographical data provided by standard web services or with proprietary formats. Typically, 3D Virtual globes like do not offer an open-source tool that allows the generation of a terrain elevation data structure starting from heterogeneous-resolution terrain datasets. This paper describes a technological solution aimed to set up a so-called “Terrain Builder”. This tool is able to merge heterogeneous-resolution datasets, and to provide a multi-resolution worldwide terrain services fully compatible with CesiumJS and therefore accessible via web using traditional browser without any additional plug-in. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terrain%20Builder" title="Terrain Builder">Terrain Builder</a>, <a href="https://publications.waset.org/abstracts/search?q=WebGL" title=" WebGL"> WebGL</a>, <a href="https://publications.waset.org/abstracts/search?q=Virtual%20Globe" title=" Virtual Globe"> Virtual Globe</a>, <a href="https://publications.waset.org/abstracts/search?q=CesiumJS" title=" CesiumJS"> CesiumJS</a>, <a href="https://publications.waset.org/abstracts/search?q=Tiled%20Map%20Service" title=" Tiled Map Service"> Tiled Map Service</a>, <a href="https://publications.waset.org/abstracts/search?q=TMS" title=" TMS"> TMS</a>, <a href="https://publications.waset.org/abstracts/search?q=Height-Map" title=" Height-Map"> Height-Map</a>, <a href="https://publications.waset.org/abstracts/search?q=Regular%20Grid" title=" Regular Grid"> Regular Grid</a>, <a href="https://publications.waset.org/abstracts/search?q=Geovisual%20Analytics" title=" Geovisual Analytics"> Geovisual Analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=DTM" title=" DTM"> DTM</a> </p> <a href="https://publications.waset.org/abstracts/35472/heterogeneous-resolution-and-multi-source-terrain-builder-for-cesiumjs-webgl-virtual-globe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35472.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">426</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">3</span> Improving Health Workers’ Well-Being in Cittadella Hospital (Province of Padua), Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emanuela%20Zilli">Emanuela Zilli</a>, <a href="https://publications.waset.org/abstracts/search?q=Suana%20Tikvina"> Suana Tikvina</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Bonaldo"> Davide Bonaldo</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Varotto"> Monica Varotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Scilla%20Rizzardi"> Scilla Rizzardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Ruzzante"> Barbara Ruzzante</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaele%20Napolitano"> Raffaele Napolitano</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Bevilacqua"> Stefano Bevilacqua</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonella%20Ruffatto"> Antonella Ruffatto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A healthy workplace increases productivity, creativity and decreases absenteeism and turnover. It also contributes to creating a more secure work environment with fewer risks of violence. In the past 3 years, the healthcare system has suffered the psychological, economic and social consequences of the COVID-19 pandemic. On the other hand, the healthcare staff reductions determine high levels of work-related stress that are often unsustainable. The Hospital of Cittadella (in the province of Padua) has 400 beds and serves a territory of 300,000 inhabitants. The hospital itself counts 1.250 healthcare employees (healthcare professionals). This year, the Medical Board of Directors has requested additional staff; however, the economic situation of Italy can not sustain additional hires. At the same time, we have initiated projects that aim to increase well-being, decrease stress and encourage activities that promote self-care. One of the projects that the hospital has organized is the psychomotor practice. It is held by therapists and trainers who operate according to the traditional method. According to the literature, the psychomotor practice is specifically intended for the staff operating in the Intensive Care Unit, Emergency Department and Pneumology Ward. The project consisted of one session of 45 minutes a week for 3 months. This method brings focus to controlled breathing, posture, muscle work and movement that help manage stress and fatigue, creating a more mindful and sustainable lifestyle. In addition, a Qigong course was held every two weeks for 5 months. It is an ancient Chinese practice designed to optimize the energy within the body, reducing stress levels and increasing general well-being. Finally, Tibetan singing crystal bowls sessions, held by a music therapist, consisted of monthly guided meditation sessions using the sounds of the crystal bowls. Sound therapy uses the vibrations created from the crystal bowls to balance the vibrations within the body to promote relaxation. In conclusion, well-being and organizational performance are closely related to each other. It is crucial for any organization to encourage and maintain better physical and mental health of the healthcare staff as it directly affects productivity and, consequently, user satisfaction of the services provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20promotion" title="health promotion">health promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20workers%20management" title=" healthcare workers management"> healthcare workers management</a>, <a href="https://publications.waset.org/abstracts/search?q=Weel%20being%20and%20organizational%20performance" title=" Weel being and organizational performance"> Weel being and organizational performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Psychomotor%20practice" title=" Psychomotor practice"> Psychomotor practice</a> </p> <a href="https://publications.waset.org/abstracts/176473/improving-health-workers-well-being-in-cittadella-hospital-province-of-padua-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176473.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">68</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">2</span> Effect of Spermidine on Physicochemical Properties of Protein Based Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sabbah">Mohammed Sabbah</a>, <a href="https://publications.waset.org/abstracts/search?q=Prospero%20Di%20Pierro"> Prospero Di Pierro</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaele%20Porta"> Raffaele Porta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Protein-based edible films and coatings have attracted an increasing interest in recent years since they might be used to protect pharmaceuticals or improve the shelf life of different food products. Among them, several plant proteins represent an abundant, inexpensive and renewable raw source. These natural biopolymers are used as film forming agents, being able to form intermolecular linkages by various interactions. However, without the addition of a plasticizing agent, many biomaterials are brittle and, consequently, very difficult to be manipulated. Plasticizers are generally small and non-volatile organic additives used to increase film extensibility and reduce its crystallinity, brittleness and water vapor permeability. Plasticizers normally act by decreasing the intermolecular forces along the polymer chains, thus reducing the relative number of polymer-polymer contacts, producing a decrease in cohesion and tensile strength and thereby increasing film flexibility allowing its deformation without rupture. The most commonly studied plasticizers are polyols, like glycerol (GLY) and some mono or oligosaccharides. In particular, GLY not only increases film extensibility but also migrates inside the film network often causing the loss of desirable mechanical properties of the material. Therefore, replacing GLY with a different plasticizer might help to improve film characteristics allowing potential industrial applications. To improve film properties, it seemed of interest to test as plasticizers some cationic small molecules like polyamines (PAs). Putrescine, spermidine (SPD), and spermine are PAs widely distributed in nature and of particular interest for their biological activities that may have some beneficial health effects. Since PAs contains amino instead of hydroxyl functional groups, they are able to trigger ionic interactions with negatively charged proteins. Bitter vetch (Vicia ervilia; BV) is an ancient grain legume crop, originated in the Mediterranean region, which can be found today in many countries around the world. This annual Vicia genus shows several favorable features, being their seeds a cheap and abundant protein source. The main objectives of this study were to investigate the effect of different concentrations of SPD on the mechanical and permeability properties of films prepared with native or heat denatured BV proteins in the presence of different concentrations of SPD and/or GLY. Therefore, a BV seed protein concentrate (BVPC), containing about 77% proteins, was used to prepare film forming solutions (FFSs), whereas GLY and SPD were added as film plasticizers, either singly or in combination, at various concentrations. Since a primary plasticizer is generally defined as a molecule that when added to a material makes it softer, more flexible and easier to be processed, our findings lead to consider SPD as a possible primary plasticizer of protein-based films. In fact, the addition of millimolar concentrations of SPD to BVPC FFS allowed obtaining handleable biomaterials with improved properties. Moreover, SPD can be also considered as a secondary plasticizer, namely an 'extender', because of its ability even to enhance the plasticizing performance of GLY. In conclusion, our studies indicate that innovative edible protein-based films and coatings can be obtained by using PAs as new plasticizers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edible%20films" title="edible films">edible films</a>, <a href="https://publications.waset.org/abstracts/search?q=glycerol" title=" glycerol"> glycerol</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticizers" title=" plasticizers"> plasticizers</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamines" title=" polyamines"> polyamines</a>, <a href="https://publications.waset.org/abstracts/search?q=spermidine" title=" spermidine"> spermidine</a> </p> <a href="https://publications.waset.org/abstracts/79359/effect-of-spermidine-on-physicochemical-properties-of-protein-based-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79359.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">197</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">1</span> A Single Cell Omics Experiments as Tool for Benchmarking Bioinformatics Oncology Data Analysis Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maddalena%20Arigoni">Maddalena Arigoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Luisa%20Ratto"> Maria Luisa Ratto</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaele%20A.%20Calogero"> Raffaele A.

Understanding the causes and progression of cancer requires research efforts aimed at characterizing heterogeneity, which can be facilitated by evolving single-cell sequencing technologies. However, analyzing single-cell data necessitates computational methods that often lack objective validation. Therefore, the establishment of benchmarking datasets is necessary to provide a controlled environment for validating bioinformatics tools in the field of single-cell oncology. Benchmarking bioinformatics tools for single-cell experiments can be costly due to the high expense involved. Therefore, datasets used for benchmarking are typically sourced from publicly available experiments, which often lack a comprehensive cell annotation. This limitation can affect the accuracy and effectiveness of such experiments as benchmarking tools. To address this issue, we introduce omics benchmark experiments designed to evaluate bioinformatics tools to depict the heterogeneity in single-cell tumor experiments. We conducted single-cell RNA sequencing on six lung cancer tumor cell lines that display resistant clones upon treatment of EGFR mutated tumors and are characterized by driver genes, namely ROS1, ALK, HER2, MET, KRAS, and BRAF. These driver genes are associated with downstream networks controlled by EGFR mutations, such as JAK-STAT, PI3K-AKT-mTOR, and MEK-ERK. The experiment also featured an EGFR-mutated cell line. Using 10XGenomics platform with cellplex technology, we analyzed the seven cell lines together with a pseudo-immunological microenvironment consisting of PBMC cells labeled with the Biolegend TotalSeq™-B Human Universal Cocktail (CITEseq). This technology allowed for independent labeling of each cell line and single-cell analysis of the pooled seven cell lines and the pseudo-microenvironment. The data generated from the aforementioned experiments are available as part of an online tool, which allows users to define cell heterogeneity and generates count tables as an output. The tool provides the cell line derivation for each cell and cell annotations for the pseudo-microenvironment based on CITEseq data by an experienced immunologist. Additionally, we created a range of pseudo-tumor tissues using different ratios of the aforementioned cells embedded in matrigel. These tissues were analyzed using 10XGenomics (FFPE samples) and Curio Bioscience (fresh frozen samples) platforms for spatial transcriptomics, further expanding the scope of our benchmark experiments. The benchmark experiments we conducted provide a unique opportunity to evaluate the performance of bioinformatics tools for detecting and characterizing tumor heterogeneity at the single-cell level. Overall, our experiments provide a controlled and standardized environment for assessing the accuracy and robustness of bioinformatics tools for studying tumor heterogeneity at the single-cell level, which can ultimately lead to more precise and effective cancer diagnosis and treatment. <p class="card-text"><strong>Keywords:</strong> <a
