To further improve the performance of the simulation model and extend the application range to both dichromats or anomalous trichromats, we have proposed a simulation model of cone fundamentals specifically designed for individuals with red-green type color vision deficiency (CVD) based on the CIE 2006 physiological observer model. By utilizing the simulated cone fundamentals, it becomes possible to predict the color appearance of real scenes and digital images for CVD. The fundamental premise of the new model is rooted in the hypothesis that CVD arises from a shift in the peak wavelength of the photopigment absorption spectrum of the L or M cone. Instead of simply maintaining the waveform without alteration as observed in prior studies, we altered waveforms of the absorption spectra of anomalous L/M cone photopigments when adjusting their peak wavelengths. Regarding different shapes in the absorption spectrum between the L and M cone, the absorption spectrum of the anomalous L/M cone was obtained by combining the peak wavenumber shift and linear interpolation of spectral quantal absorption curves between L- and M-photopigments in the wavenumber domain. The performance of the proposed model was substantiated through experimental validation by the pseudoisochromatic plates and Farnsworth Munsell 100 Hue test (FM-100). The findings revealed a high level of consistency between the model prediction and the actual perception reported by individuals with CVD. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2502.10316v1-abstract-full').style.display = 'none'; document.getElementById('2502.10316v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2502.09951">arXiv:2502.09951</a> <span> [<a href="https://arxiv.org/pdf/2502.09951">pdf</a>, <a href="https://arxiv.org/format/2502.09951">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Evidence of the P_ccbars(4459)0 in Upsilon(1S, 2S) inclusive decays at Belle </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Adachi%2C+I">I.

Using the first observations of Upsilon(1S, 2S) inclusive decays to Jpsi Lambda, we find evidence of the P_ccbars(4459)0 state with a significance of 3.3 standard deviations, including statistical and systematic uncertainties. We measure the mass and width of the Pccbars(4459)0 to be (4471.7 +- 4.8 +- 0.6) MeV/c2 and (21.9 +- 13.1 +- 2.7) MeV, respectively. The branching fractions for P_ccbars(4459)0 production are measured to be B[Upsilon(1S) -> P_ccbars(4459)0/ Pbar_ccbars(4459)0 + anything] = (3.5 +- 2.0 +- 0.2)*10-6 and B[Upsilin(2S) -> P_ccbars(4459)0/ Pbar_ccbars(4459)0 +anything] = (2.9 +- 1.7 +- 0.4)*10-6. The inclusive branching fractions of Upsilon(1S, 2S) -> Jpsi Lambda/Lambdabar are measured to be B[Upsilin(1S) -> Jpsi Lambda/Lambdabar + anything] = (36.9 +- 5.3 +- 2.4)*10-6 and B[Upsilon(2S) -> Jpsi Lambda/Lambdabar + anything] = (22.3 +- 5.7 +- 3.1)*10-6. We measure the visible cross section sigma(e+e- -> Jpsi Lambda/Lambdabar + anything) = (90 +- 14 +- 6) fb for the continuum production at sqrt(s) = 10.52 GeV. In all cases, the first uncertainties are statistical and the second are systematic. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2502.09951v1-abstract-full').style.display = 'none'; document.getElementById('2502.09951v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">8 pages, 3 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> Belle II Preprint 2025-002, KEK Preprint 2024-50 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2502.09464">arXiv:2502.09464</a> <span> [<a href="https://arxiv.org/pdf/2502.09464">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> </div> <p class="title is-5 mathjax"> Unexpected large electrostatic gating by pyroelectric charge accumulation </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Mou%2C+Y">Yicheng Mou</a>, <a href="/search/?searchtype=author&query=Liu%2C+Q">Qi Liu</a>, <a href="/search/?searchtype=author&query=Liu%2C+J">Jiaqi Liu</a>, <a href="/search/?searchtype=author&query=Xia%2C+Y">Yingchao Xia</a>, <a href="/search/?searchtype=author&query=Guo%2C+Z">Zejing Guo</a>, <a href="/search/?searchtype=author&query=Song%2C+W">Wenqing Song</a>, <a href="/search/?searchtype=author&query=Gu%2C+J">Jiaming Gu</a>, <a href="/search/?searchtype=author&query=Xu%2C+Z">Zixuan Xu</a>, <a href="/search/?searchtype=author&query=Wang%2C+W">Wenbin Wang</a>, <a href="/search/?searchtype=author&query=Guo%2C+H">Hangwen Guo</a>, <a href="/search/?searchtype=author&query=Shi%2C+W">Wu Shi</a>, <a href="/search/?searchtype=author&query=Shen%2C+J">Jian Shen</a>, <a href="/search/?searchtype=author&query=Zhang%2C+C">Cheng Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2502.09464v1-abstract-short" style="display: inline;"> Pyroelectricity refers to the accumulation of charges due to changes in the spontaneous polarization of ferroelectric materials when subjected to temperature variations.

Typically, these pyroelectric charges are considered unstable and dissipate quickly through interactions with the external environment. Consequently, the pyroelectric effect has been largely overlooked in ferroelectric field-effect transistors. In this work, we leverage the van der Waals interface of hBN to achieve a substantial and long-term electrostatic gating effect in graphene devices via the pyroelectric properties of a ferroelectric LiNbO3 substrate. Upon cooling, the polarization change in LiNbO3 induces high doping concentrations up to 1013 cm-2 in the adjacent graphene. Through a combination of transport measurements and non-contact techniques, we demonstrate that the pyroelectric charge accumulation, as well as its enhancement in electric fields, are responsible for this unexpectedly high doping level. Our findings introduce a novel mechanism for voltage-free electrostatic gating control with long retention. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2502.09464v1-abstract-full').style.display = 'none'; document.getElementById('2502.09464v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">16 pages, 4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2502.09458">arXiv:2502.09458</a> <span> [<a href="https://arxiv.org/pdf/2502.09458">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1021/acsphotonics.4c02182">10.1021/acsphotonics.4c02182 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Broadband photoresponse enhancement by band engineering in Sb-doped MnBi2Te4 </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Xu%2C+Z">Zixuan Xu</a>, <a href="/search/?searchtype=author&query=Chen%2C+H">Haonan Chen</a>, <a href="/search/?searchtype=author&query=Wang%2C+J">Jiayu Wang</a>, <a href="/search/?searchtype=author&query=Mou%2C+Y">Yicheng Mou</a>, <a href="/search/?searchtype=author&query=Xia%2C+Y">Yingchao Xia</a>, <a href="/search/?searchtype=author&query=Gu%2C+J">Jiaming Gu</a>, <a href="/search/?searchtype=author&query=Wang%2C+Y">Yuxiang Wang</a>, <a href="/search/?searchtype=author&query=Liu%2C+Q">Qi Liu</a>, <a href="/search/?searchtype=author&query=Liu%2C+J">Jiaqi Liu</a>, <a href="/search/?searchtype=author&query=Song%2C+W">Wenqing Song</a>, <a href="/search/?searchtype=author&query=Lan%2C+Q">Qing Lan</a>, <a href="/search/?searchtype=author&query=Zhao%2C+T">Tuoyu Zhao</a>, <a href="/search/?searchtype=author&query=Shi%2C+W">Wu Shi</a>, <a href="/search/?searchtype=author&query=Zhang%2C+C">Cheng Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2502.09458v1-abstract-short" style="display: inline;"> Topological materials have attracted considerable attention for their potential in broadband and fast photoresponse, particularly in the infrared regime.

However, the high carrier concentration in these systems often leads to rapid recombination of photogenerated carriers, limiting the photoresponsivity. Here, we demonstrate that Sb doping in MnBi2Te4 effectively reduces carrier concentration and suppresses electron-hole recombination, thereby significantly improving the optoelectronic performance across the visible to mid-infrared spectra. The optimally doped Mn(Bi0.82Sb0.18)2Te4 photodetector achieves a responsivity of 3.02 mA W-1 with a response time of 18.5 渭s at 1550 nm, and 0.795 mA W-1 with a response time of 9.0 渭s at 4 渭m. These values represent nearly two orders of magnitude improvement compared to undoped MnBi2Te4. Our results highlight band engineering as an effective strategy to enhance the infrared performance of topological material-based photodetectors, opening new avenues for high-sensitivity infrared detection. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2502.09458v1-abstract-full').style.display = 'none'; document.getElementById('2502.09458v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">14 pages, 4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2502.08929">arXiv:2502.08929</a> <span> [<a href="https://arxiv.org/pdf/2502.08929">pdf</a>, <a href="https://arxiv.org/ps/2502.08929">ps</a>, <a href="https://arxiv.org/format/2502.08929">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Precise Measurement of the $蠂_{c0}$ Resonance Parameters and Branching Fractions of $蠂_{c0,c2}\to蟺^+蟺^-/K^+K^-$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

These measurements improve the precision of $蠂_{c0}$ mass by a factor of four and width by one order of magnitude over the previous individual measurements, and significantly boost our knowledge about the charmonium spectrum. Together with additional $(345.4\pm2.6)\times10^{6}$ $蠄(3686)$ data events taken in 2012, the decay branching fractions of $蠂_{c0,c2}\to蟺^+蟺^-/K^+K^-$ are measured as well, with precision improved by a factor of three compared to previous measurements.

The proposed method leverages deep learning-based illumination-resilient features and LiDAR-Inertial-Visual Odometry (LIVO). By incorporating advanced techniques such as uniform depth distribution of features enabled by depth association with LiDAR point clouds and adaptive feature matching utilizing Superpoint and LightGlue, LIR-LIVO achieves state-of-the-art (SOTA) accuracy and robustness with low computational cost. Experiments are conducted on benchmark datasets, including NTU-VIRAL, Hilti'22, and R3LIVE-Dataset. The corresponding results demonstrate that our proposed method outperforms other SOTA methods on both standard and challenging datasets. Particularly, the proposed method demonstrates robust pose estimation under poor ambient lighting conditions in the Hilti'22 dataset.

Spatial computing enables interaction with virtual elements through natural input methods such as eye tracking, hand gestures, and voice commands, thus placing natural human-computer interaction at its core. While previous surveys have reviewed conventional XR interaction techniques, recent advancements in natural interaction, particularly driven by artificial intelligence (AI) and large language models (LLMs), have introduced new paradigms and technologies. In this paper, we review research on multimodal natural interaction for wearable XR, focusing on papers published between 2022 and 2024 in six top venues: ACM CHI, UIST, IMWUT (Ubicomp), IEEE VR, ISMAR, and TVCG. We classify and analyze these studies based on application scenarios, operation types, and interaction modalities. This analysis provides a structured framework for understanding how researchers are designing advanced natural interaction techniques in XR. Based on these findings, we discuss the challenges in natural interaction techniques and suggest potential directions for future research. This review provides valuable insights for researchers aiming to design natural and efficient interaction systems for XR, ultimately contributing to the advancement of spatial computing. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2502.07598v1-abstract-full').style.display = 'none'; document.getElementById('2502.07598v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 11 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">28 pages, 10 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2502.07477">arXiv:2502.07477</a> <span> [<a href="https://arxiv.org/pdf/2502.07477">pdf</a>, <a href="https://arxiv.org/format/2502.07477">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> </div> <p class="title is-5 mathjax"> Robust zero modes in PbTe-Pb hybrid nanowires </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Zhang%2C+S">Shan Zhang</a>, <a href="/search/?searchtype=author&query=Song%2C+W">Wenyu Song</a>, <a href="/search/?searchtype=author&query=Li%2C+Z">Zonglin Li</a>, <a href="/search/?searchtype=author&query=Yu%2C+Z">Zehao Yu</a>, <a href="/search/?searchtype=author&query=Li%2C+R">Ruidong Li</a>, <a href="/search/?searchtype=author&query=Wang%2C+Y">Yuhao Wang</a>, <a href="/search/?searchtype=author&query=Yan%2C+Z">Zeyu Yan</a>, <a href="/search/?searchtype=author&query=Xu%2C+J">Jiaye Xu</a>, <a href="/search/?searchtype=author&query=Wang%2C+Z">Zhaoyu Wang</a>, <a href="/search/?searchtype=author&query=Gao%2C+Y">Yichun Gao</a>, <a href="/search/?searchtype=author&query=Yang%2C+S">Shuai Yang</a>, <a href="/search/?searchtype=author&query=Yang%2C+L">Lining Yang</a>, <a href="/search/?searchtype=author&query=Feng%2C+X">Xiao Feng</a>, <a href="/search/?searchtype=author&query=Wang%2C+T">Tiantian Wang</a>, <a href="/search/?searchtype=author&query=Zang%2C+Y">Yunyi Zang</a>, <a href="/search/?searchtype=author&query=Li%2C+L">Lin Li</a>, <a href="/search/?searchtype=author&query=Shang%2C+R">Runan Shang</a>, <a href="/search/?searchtype=author&query=Xue%2C+Q">Qi-Kun Xue</a>, <a href="/search/?searchtype=author&query=He%2C+K">Ke He</a>, <a href="/search/?searchtype=author&query=Zhang%2C+H">Hao Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2502.07477v1-abstract-short" style="display: inline;"> Majorana zero modes in tunneling conductance are expected to manifest as robust zero bias peaks (ZBPs).

Their decay branching fractions are determined to be ${\mathcal B}[D^{+}\to \bar{K}_1(1270)^0 渭^{+}谓_渭]=(2.36\pm0.20^{+0.18}_{-0.27}\pm 0.48)\times10^{-3}$ and ${\mathcal B}[D^{0}\to K_1(1270)^{-} 渭^{+}谓_渭]=(0.78\pm0.11^{+0.05}_{-0.09}\pm 0.15)\times10^{-3}$, where the first and second uncertainties are statistical and systematic, respectively, and the third originates from the input branching fraction of $\bar K_{1}(1270)^0\to K^- 蟺^+蟺^0$ or $K_1(1270)^-\to K^-蟺^+蟺^-$. Combining our branching fractions with the previous measurements of ${\mathcal B}[D^+\to \bar K_1(1270)^0e^+谓_{e}]$ and ${\mathcal B}[D^0\to K_1(1270)^-e^+谓_{e}]$, we determine the branching fraction ratios to be ${\mathcal B}[D^+\to \bar K_1(1270)^0渭^+谓_渭]/{\mathcal B}[D^+\to \bar K_1(1270)^0e^+谓_{e}]=1.03 \pm 0.14 \substack{+0.11\\-0.15}$ and ${\mathcal B}[D^0\to K_1(1270)^-渭^+谓_渭]/{\mathcal B}[D^0\to K_1(1270)^-e^+谓_{e}]=0.74\pm 0.13 \substack{+0.08\\-0.13}$.

Among these materials, the magnetic semiconductor CrSBr is possibly a first playground where we can study simultaneously the interaction of photons, magnons, and excitons at the quantum level. Here we demonstrate a coherent macroscopic quantum phase, the bosonic condensation of exciton-polaritons, which emerges in a CrSBr flake embedded in a fully tunable cryogenic open optical cavity. The Bose condensate is characterized by a highly non-linear threshold-like behavior, and coherence manifests distinctly via its first and second order quantum coherence. We find that the condensate's non-linearity is highly susceptible to the magnetic order in CrSBr, and encounters a sign change depending on the antiferro- and ferromagnetic ordering. Our findings open a route towards magnetically controllable quantum fluids of light, and optomagnonic devices where spin magnetism is coupled to on-chip Bose-Einstein condensates. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.18233v1-abstract-full').style.display = 'none'; document.getElementById('2501.18233v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 30 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">35 pages, 12 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.15447">arXiv:2501.15447</a> <span> [<a href="https://arxiv.org/pdf/2501.15447">pdf</a>, <a href="https://arxiv.org/ps/2501.15447">ps</a>, <a href="https://arxiv.org/format/2501.15447">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Observation of $h_{c}$ radiative decays to multiple light hadrons and the tensor state $f_2(1270)$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

To achieve fluent and high-quality interaction across modalities without compromising the capabilities of any modality, we prioritized optimizing three key aspects. First, we establish a comprehensive data cleaning and synthesis pipeline for multimodal data, obtaining about 500B high-quality data (text, audio, and vision). Second, an audio-tokenizer (Baichuan-Audio-Tokenizer) has been designed to capture both semantic and acoustic information from audio, enabling seamless integration and enhanced compatibility with MLLM. Lastly, we designed a multi-stage training strategy that progressively integrates multimodal alignment and multitask fine-tuning, ensuring effective synergy across all modalities. Baichuan-Omni-1.5 leads contemporary models (including GPT4o-mini and MiniCPM-o 2.6) in terms of comprehensive omni-modal capabilities. Notably, it achieves results comparable to leading models such as Qwen2-VL-72B across various multimodal medical benchmarks. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.15368v1-abstract-full').style.display = 'none'; document.getElementById('2501.15368v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 25 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.14206">arXiv:2501.14206</a> <span> [<a href="https://arxiv.org/pdf/2501.14206">pdf</a>, <a href="https://arxiv.org/ps/2501.14206">ps</a>, <a href="https://arxiv.org/format/2501.14206">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Cross section measurement of $e^{+}e^{-} \to f_{1}(1285)蟺^{+}蟺^{-}$ at center-of-mass energies between $3.808$ and $4.951\rm GeV$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

To address this, we propose MultiDreamer3D that can generate coherent multi-concept 3D content in a divide-and-conquer manner. First, we generate 3D bounding boxes using an LLM-based layout controller. Next, a selective point cloud generator creates coarse point clouds for each concept. These point clouds are placed in the 3D bounding boxes and initialized into 3D Gaussian Splatting with concept labels, enabling precise identification of concept attributions in 2D projections. Finally, we refine 3D Gaussians via concept-aware interval score matching, guided by concept-aware diffusion. Our experimental results show that MultiDreamer3D not only ensures object presence and preserves the distinct identities of each concept but also successfully handles complex cases such as property change or interaction. To the best of our knowledge, we are the first to address the multi-concept customization in 3D. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.13449v1-abstract-full').style.display = 'none'; document.getElementById('2501.13449v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 23 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">9 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.10130">arXiv:2501.10130</a> <span> [<a href="https://arxiv.org/pdf/2501.10130">pdf</a>, <a href="https://arxiv.org/format/2501.10130">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Study of $畏\rightarrow蟺^+蟺^-l^+l^-$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

Evidence obtained using photons with distinct probing depths shows that conduction is localized primarily at the first unit cell near the interface. Scanning transmission electron microscopy (STEM), together with energy-dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS), indicates that interfacial Sr diffusion and pronounced oxygen 2p hybridization gradient may collectively account for the interfacial confinement of conduction. Fermi surface maps reveal hole doping compared to non-superconducting ambient-pressure bulk crystals. Measurements of dispersive band structures suggest the contributions from both Ni $d_{x^2-y^2}$ and $d_{z^2}$ orbitals at the Fermi level. Density functional theory (DFT) + U calculations capture qualitative features of the ARPES results, consistent with a hole-doped scenario. These findings constrain theoretical models of the superconducting mechanism and suggest pathways for enhancing superconductivity in nickelates under ambient pressure. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.09255v1-abstract-full').style.display = 'none'; document.getElementById('2501.09255v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 15 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">under review</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.08080">arXiv:2501.08080</a> <span> [<a href="https://arxiv.org/pdf/2501.08080">pdf</a>, <a href="https://arxiv.org/format/2501.08080">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Search for the FCNC charmonium decay $J/蠄\to D^0 渭^+ 渭^- + \text{c.c.}$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

This study addresses these challenges by optimizing the design and control strategies of an energy system that meets the heat and electricity demands of a community. The proposed system integrates solar and wind power with energy storage, including seasonal thermal energy storage (STES) and battery, coupled via a heat pump. This approach enhances self-sufficiency and effectively mitigates seasonal mismatches. To model heat transfer between the storage and the ground in the STES system, we employ a multi-node lumped-parameter method. The optimization problem is formulated as a periodic optimal control problem, which is then transcribed into a nonlinear programming problem. To reduce computational complexity, we apply the averaging method, which significantly lowers the effort required to solve the problem. We apply this approach to a case study, where the economically optimized configuration results in a projected total energy cost per household of approximately 75 EUR/month over 30 years for both heat and electricity. This study demonstrates the feasibility of designing economically viable, autonomous energy communities in real-world scenarios, and provides a comprehensive optimization framework for designing system components and control strategies. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.07427v1-abstract-full').style.display = 'none'; document.getElementById('2501.07427v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">35 pages, 12 figures, submitted to Renewable Energy.

By this work, we investigated the CP violation in the cascade decay process $D^0(t_1) \to 蟺^0 K(t_2) \to 蟺^0(蟺^\pm \ell^\mp 谓)$. Our results indicate that the CP violation induced by the interference of unmixed $D$-meson decay amplitudes dominates, with a peak value reaching $5 \times 10^{-3}$. This is one order of magnitude larger than the sub-leading contribution, namely the double-mixing CP violation. Furthermore, the CP violation in the decay channel with the semileptonic final state $蟺^- \ell^+ 谓_\ell$ is one to two orders of magnitude larger than that in the channel with $ 蟺^+ \ell^- \bar谓_\ell$. We propose that the CP asymmetry of the combined two decay channels can be measured experimentally. The resulting value is approximately half of the CP violation observed in the $蟺^- \ell^+ 谓_\ell$ channel, with the dominant contribution still reaching the order of $10^{-3}$. This approach offers the advantage of eliminating the need for flavor tagging of the initial $D$ meson, thereby avoiding associated efficiency losses. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.05689v1-abstract-full').style.display = 'none'; document.getElementById('2501.05689v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.04760">arXiv:2501.04760</a> <span> [<a href="https://arxiv.org/pdf/2501.04760">pdf</a>, <a href="https://arxiv.org/format/2501.04760">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Search for the leptonic decay $D^{+}\to e^{+}谓_{e}$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

Moreover, the branching fraction of $D_s^+ \to 蠁蟻^+$ is measured to be $(3.98\pm0.33_{\rm stat}\pm0.21_{\rm syst})\%$, and the $R_蠁= {\mathcal{B}(蠁\to蟺^+蟺^-蟺^0)}/{\mathcal{B}(蠁\to K^+K^-)}$ is determined to be $(0.222\pm0.019_{\rm stat}\pm0.016_{\rm syst}$), which is consistent with the previous measurement based on charm meson decays, but deviates from the results from $e^+e^-$ annihilation and $K$-$N$ scattering experiments by more than 3$蟽$. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.04451v1-abstract-full').style.display = 'none'; document.getElementById('2501.04451v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 8 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.04345">arXiv:2501.04345</a> <span> [<a href="https://arxiv.org/pdf/2501.04345">pdf</a>, <a href="https://arxiv.org/format/2501.04345">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> </div> <p class="title is-5 mathjax"> Anisotropy of PbTe nanowires with and without a superconductor </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Li%2C+Z">Zonglin Li</a>, <a href="/search/?searchtype=author&query=Song%2C+W">Wenyu Song</a>, <a href="/search/?searchtype=author&query=Zhang%2C+S">Shan Zhang</a>, <a href="/search/?searchtype=author&query=Wang%2C+Y">Yuhao Wang</a>, <a href="/search/?searchtype=author&query=Wang%2C+Z">Zhaoyu Wang</a>, <a href="/search/?searchtype=author&query=Yu%2C+Z">Zehao Yu</a>, <a href="/search/?searchtype=author&query=Li%2C+R">Ruidong Li</a>, <a href="/search/?searchtype=author&query=Yan%2C+Z">Zeyu Yan</a>, <a href="/search/?searchtype=author&query=Xu%2C+J">Jiaye Xu</a>, <a href="/search/?searchtype=author&query=Gao%2C+Y">Yichun Gao</a>, <a href="/search/?searchtype=author&query=Yang%2C+S">Shuai Yang</a>, <a href="/search/?searchtype=author&query=Yang%2C+L">Lining Yang</a>, <a href="/search/?searchtype=author&query=Feng%2C+X">Xiao Feng</a>, <a href="/search/?searchtype=author&query=Wang%2C+T">Tiantian Wang</a>, <a href="/search/?searchtype=author&query=Zang%2C+Y">Yunyi Zang</a>, <a href="/search/?searchtype=author&query=Li%2C+L">Lin Li</a>, <a href="/search/?searchtype=author&query=Shang%2C+R">Runan Shang</a>, <a href="/search/?searchtype=author&query=Xue%2C+Q">Qi-Kun Xue</a>, <a href="/search/?searchtype=author&query=He%2C+K">Ke He</a>, <a href="/search/?searchtype=author&query=Zhang%2C+H">Hao Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2501.04345v1-abstract-short" style="display: inline;"> We investigate the anisotropic behaviors in PbTe and PbTe-Pb hybrid nanowires.

Here, we achieve reproducible anisotropy in PbTe nanowires through a substantial reduction of disorder. We then couple PbTe to a superconductor Pb, and observe a pronounced deviation in the anisotropy behavior compared to bare PbTe nanowires. This deviation is gate-tunable and attributed to spin-orbit interaction and orbital effect, controlled by charge transfer between Pb and PbTe.

The di-electron-invariant-mass dependent transition form factor of this decay is explored for the first time. A significant resonant structure corresponding to the $蟻/蠅$ resonance is observed, which cannot be described by existing theoretical models, due to contributions from the isospin-conserving $J/蠄\to 蟻蟺^0$ and isospin-volating $J/蠄\to 蠅蟺^0$ decays. The observed $蟻$--$蠅$ interference is consistent with that of the pion form factor but features a relatively narrow $蟻$ peak. By taking into account the contribution of this resonant structure, the branching fraction of $J/蠄\to e^+e^- 蟺^0$ in the full $e^+e^-$ invariant mass spectrum range is also measured for the first time to be $(8.06 \pm 0.31 (\rm{stat}) \pm 0.38 (\rm{syst}))\times 10^{-7}$, which is two times larger than the prediction of the Vector Meson Dominance model due to the observed resonant contribution of $蟻/蠅$ resonances. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.04344v1-abstract-full').style.display = 'none'; document.getElementById('2501.04344v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 8 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">9 pages, 4 figures, Submitted to Phys.

According to Levenshtein's work in 2001, this number is determined by the size of the maximum intersection between the error balls of any two distinct input sequences of the channel. In this work, we study the sequence reconstruction problem for single-deletion single-substitution channel, assuming that the transmitted sequence belongs to a $q$-ary code with minimum Hamming distance at least $2$, where $q\geq 2$ is any fixed integer. Specifically, we prove that for any two $q$-ary sequences of length $n$ and with Hamming distance $d\geq 2$, the size of the intersection of their error balls is upper bounded by $2qn-3q-2-未_{q,2}$, where $未_{i,j}$ is the Kronecker delta. We also prove the tightness of this bound by constructing two sequences the intersection size of whose error balls achieves this bound. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.03833v4-abstract-full').style.display = 'none'; document.getElementById('2501.03833v4-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 7 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.02594">arXiv:2501.02594</a> <span> [<a href="https://arxiv.org/pdf/2501.02594">pdf</a>, <a href="https://arxiv.org/format/2501.02594">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Observation of $蠄(3686) \to K^{-}螞(1520)\bar螢^{+} + c.c.$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

Achieving this requires sufficient data; however, unauthorized access by an eavesdropping learner can lead to security risks. Thus, it is important to ensure the performance of the "authorized" learner by limiting the quality of the training data accessible to eavesdroppers. Unlike previous studies focusing on encryption or access controls, we provide a theorem to ensure superior learning outcomes exclusively for the authorized learner with quantum label encoding. In this context, we use the probably-approximately-correct (PAC) learning framework and introduce the concept of learning probability to quantitatively assess learner performance. Our theorem allows the condition that, given a training dataset, an authorized learner is guaranteed to achieve a certain quality of learning outcome, while eavesdroppers are not. Notably, this condition can be constructed based only on the authorized-learning-only measurable quantities of the training data, i.e., its size and noise degree. We validate our theoretical proofs and predictions through convolutional neural networks (CNNs) image classification learning. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.00754v1-abstract-full').style.display = 'none'; document.getElementById('2501.00754v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 1 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">17 pages, 7 figures, comments welcome</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2501.00751">arXiv:2501.00751</a> <span> [<a href="https://arxiv.org/pdf/2501.00751">pdf</a>, <a href="https://arxiv.org/format/2501.00751">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Image and Video Processing">eess.IV</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Computer Vision and Pattern Recognition">cs.CV</span> </div> </div> <p class="title is-5 mathjax"> HCMA-UNet: A Hybrid CNN-Mamba UNet with Inter-Slice Self-Attention for Efficient Breast Cancer Segmentation </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Li%2C+H">Haoxuan Li</a>, <a href="/search/?searchtype=author&query=song%2C+W">Wei song</a>, <a href="/search/?searchtype=author&query=Qin%2C+P">Peiwu Qin</a>, <a href="/search/?searchtype=author&query=Yuan%2C+X">Xi Yuan</a>, <a href="/search/?searchtype=author&query=Chen%2C+Z">Zhenglin Chen</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2501.00751v1-abstract-short" style="display: inline;"> Breast cancer lesion segmentation in DCE-MRI remains challenging due to heterogeneous tumor morphology and indistinct boundaries.

To address these challenges, this study proposes a novel hybrid segmentation network, HCMA-UNet, for lesion segmentation of breast cancer. Our network consists of a lightweight CNN backbone and a Multi-view Inter-Slice Self-Attention Mamba (MISM) module. The MISM module integrates Visual State Space Block (VSSB) and Inter-Slice Self-Attention (ISSA) mechanism, effectively reducing parameters through Asymmetric Split Channel (ASC) strategy to achieve efficient tri-directional feature extraction. Our lightweight model achieves superior performance with 2.87M parameters and 126.44 GFLOPs. A Feature-guided Region-aware loss function (FRLoss) is proposed to enhance segmentation accuracy. Extensive experiments on one private and two public DCE-MRI breast cancer datasets demonstrate that our approach achieves state-of-the-art performance while maintaining computational efficiency. FRLoss also exhibits good cross-architecture generalization capabilities.

It allows the AI model to understand the spatial information of a surgical scene. Meanwhile, due to the lack of annotated surgical data, surgery segmentation models suffer from limited performance. With the emergence of SAM2 model, a large foundation model for video segmentation trained on natural videos, zero-shot surgical video segmentation became more realistic but meanwhile remains to be explored. In this paper, we systematically evaluate the performance of SAM2 model in zero-shot surgery video segmentation task. We conducted experiments under different configurations, including different prompting strategies, robustness, etc. Moreover, we conducted an empirical evaluation over the performance, including 9 datasets with 17 different types of surgeries. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.00525v1-abstract-full').style.display = 'none'; document.getElementById('2501.00525v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 31 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.20305">arXiv:2412.20305</a> <span> [<a href="https://arxiv.org/pdf/2412.20305">pdf</a>, <a href="https://arxiv.org/ps/2412.20305">ps</a>, <a href="https://arxiv.org/format/2412.20305">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Measurement of Born cross section of $e^+e^-\to危^0\bar危^0$ at $\sqrt{s} = 3.50-4.95$ GeV </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

In addition, we set an upper limit on the branching fraction of $畏\to e^{+}e^{-}渭^{+}渭^{-}$ to be $6.88 \times {10^{-6}}$, which improves the previous result by about two orders of magnitude. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.19702v1-abstract-full').style.display = 'none'; document.getElementById('2412.19702v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">11 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.19624">arXiv:2412.19624</a> <span> [<a href="https://arxiv.org/pdf/2412.19624">pdf</a>, <a href="https://arxiv.org/format/2412.19624">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Measurement of the branching fraction, polarization, and time-dependent $CP$ asymmetry in $B^0 \to 蟻^+蟻^-$ decays and constraint on the CKM angle $蠁_2$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Belle+II+Collaboration"> Belle II Collaboration</a>, <a href="/search/?searchtype=author&query=Adachi%2C+I">I.

With the development of convolutional neural networks (CNNs), concepts like residual connection and multiple scales promote continual performance gains in diverse deep learning vision tasks. In this paper, we propose a novel CNN architecture that it consists of residual feature-reutilization inceptions (ResFRI) or split-residual feature-reutilization inceptions (Split-ResFRI). And it is composed of four convolutional combinations of different structures connected by specially designed information interaction passages, which are utilized to extract multi-scale feature information and effectively increase the receptive field of the model. Moreover, according to the network structure designed above, Split-ResFRI can adjust the segmentation ratio of the input information, thereby reducing the number of parameters and guaranteeing the model performance. Specifically, in experiments based on popular vision datasets, such as CIFAR10 ($97.94$\%), CIFAR100 ($85.91$\%) and Tiny Imagenet ($70.54$\%), we obtain state-of-the-art results compared with other modern models under the premise that the model size is approximate and no additional data is used. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.19433v1-abstract-full').style.display = 'none'; document.getElementById('2412.19433v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">arXiv admin note: substantial text overlap with arXiv:2301.00424</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.16470">arXiv:2412.16470</a> <span> [<a href="https://arxiv.org/pdf/2412.16470">pdf</a>, <a href="https://arxiv.org/format/2412.16470">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Search for lepton flavor-violating decay modes $B^0\to K_S^0蟿^\pm\ell^\mp~(\ell=渭, e)$ with hadronic $B$-tagging at Belle and Belle II </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Belle"> Belle</a>, <a href="/search/?searchtype=author&query=Collaborations%2C+B+I">Belle II Collaborations</a>, <a href="/search/?searchtype=author&query=%3A"> :</a>, <a href="/search/?searchtype=author&query=Adachi%2C+I">I.

However, these charts often suffer from significant overlap between objects, resulting in substantial color interactions. Existing color blending models struggle in these scenarios, frequently leading to ambiguous color mappings and the introduction of false colors. To address these challenges, we propose an automated approach for generating optimal color encodings to enhance the perception of translucent charts. Our method harnesses color nameability to maximize the association between composite colors and their respective class labels. We introduce a color-name aware (CNA) optimization framework that generates maximally coherent color assignments and transparency settings while ensuring perceptual discriminability for all segments in the visualization. We demonstrate the effectiveness of our technique through crowdsourced experiments with composite histograms, showing how our technique can significantly outperform both standard and visualization-specific color blending models. Furthermore, we illustrate how our approach can be generalized to other visualizations, including parallel coordinates and Venn diagrams. We provide an open-source implementation of our technique as a web-based tool. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.16242v1-abstract-full').style.display = 'none'; document.getElementById('2412.16242v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">To appear in the IEEE Transactions on Visualization and Computer Graphics</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.14260">arXiv:2412.14260</a> <span> [<a href="https://arxiv.org/pdf/2412.14260">pdf</a>, <a href="https://arxiv.org/format/2412.14260">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Measurement of the branching fraction and $\it CP$-violating asymmetry of the decay $B^{0} \rightarrow 蟺^{0} 蟺^{0}$ using $387$ million bottom-antibottom meson pairs in Belle II data </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Belle+II+Collaboration"> Belle II Collaboration</a>, <a href="/search/?searchtype=author&query=Adachi%2C+I">I.

The branching fraction of this decay is measured to be $\mathcal{B}(D^0\rightarrow \bar{K}^0蟺^-e^+谓_{e}) = (1.444 \pm 0.022_{\rm stat} \pm 0.024_{\rm syst})\%$, which is the most precise to date, where the first uncertainty is statistical and the second is systematic. Based on investigation of the decay dynamics, we find that the decay is dominated by the $K^{*}(892)^-$ component and present an improved measurement of its branching fraction to be $\mathcal{B}(D^0\rightarrow K^{*}(892)^-e^+谓_e) = (2.039 \pm 0.032_{\rm stat} \pm 0.034_{\rm syst})\%$. We also determine the ratios of the hadronic form factors for the $K^{*}(892)^-e^+谓_e$ decay to be $r_{V} = V(0)/A_1(0) = 1.48 \pm 0.05_{\rm stat} \pm 0.02_{\rm syst}$ and $r_{2} = A_2(0)/A_1(0) = 0.70 \pm 0.04_{\rm stat} \pm 0.02_{\rm syst}$, where $V(0)$ is the vector form factor and $A_{1,2}(0)$ are the axial form factors. In addition, the $\bar{K}^0蟺^-$ $\mathcal{S}$-wave component is found to account for $(5.87 \pm 0.32_{\rm stat} \pm 0.16_{\rm syst})\%$ of the total decay rate, corresponding to a branching fraction of $\mathcal{B}[D^0\rightarrow (\bar{K}^0蟺^-)_{S-{\rm wave}}e^+谓_e] = (0.085 \pm 0.005_{\rm stat} \pm 0.003_{\rm syst})\%$. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.10803v1-abstract-full').style.display = 'none'; document.getElementById('2412.10803v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">20 pages, 3 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.10677">arXiv:2412.10677</a> <span> [<a href="https://arxiv.org/pdf/2412.10677">pdf</a>, <a href="https://arxiv.org/ps/2412.10677">ps</a>, <a href="https://arxiv.org/format/2412.10677">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> </div> <p class="title is-5 mathjax"> Observations of the singly Cabibbo-suppressed decays $螢_c^{+} \to pK_{S}^{0}$, $螢_c^+ \to 螞蟺^+$, and $螢_c^+ \to 危^{0} 蟺^+$ at Belle and Belle II </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Belle"> Belle</a>, <a href="/search/?searchtype=author&query=Collaborations%2C+B+I">Belle II Collaborations</a>, <a href="/search/?searchtype=author&query=%3A"> :</a>, <a href="/search/?searchtype=author&query=Adachi%2C+I">I.

It is well-known that an orthogonally invariant matrix function is an extended-real-value function defined on ${\mathbb M}_{m,n}\,(n \leqslant m)$ of the form $f \circ 蟽$ for an absolutely symmetric function $f \colon \R^n \rightarrow [-\infty,+\infty]$ and the singular values $蟽\colon {\mathbb M}_{m,n} \rightarrow \R^{n}$. We establish several second-order properties of orthogonally invariant matrix functions, such as parabolic epi-differentiability, parabolic regularity, and twice epi-differentiability when their associated absolutely symmetric functions enjoy some properties. Specifically, we show that the nuclear norm of a real $m \times n$ matrix is twice epi-differentiable and we derive an explicit expression of its second-order epi-derivative. Moreover, for a convex orthogonally invariant matrix function, we calculate its second subderivative and present sufficient conditions for twice epi-differentiability. This enables us to establish second-order optimality conditions for a class of matrix optimization problems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.09898v1-abstract-full').style.display = 'none'; document.getElementById('2412.09898v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2412.06409">arXiv:2412.06409</a> <span> [<a href="https://arxiv.org/pdf/2412.06409">pdf</a>, <a href="https://arxiv.org/ps/2412.06409">ps</a>, <a href="https://arxiv.org/format/2412.06409">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Study of the decay 蠄(3686) \to 危^{0}\bar危^{0}蠁 </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/?searchtype=author&query=Ablikim%2C+M">M.

LLM-based approaches can either insert the correct code or directly generate patches when provided with buggy methods. However, most of LLM-based APR methods rely on a single type of software information, without fully leveraging different software artifacts. Despite this, many LLM-based approaches do not explore which specific types of information best assist in APR. Addressing this gap is crucial for advancing LLM-based APR techniques. We propose DEVLoRe to use issue content (description and message) and stack error traces to localize buggy methods, then rely on debug information in buggy methods and issue content and stack error to localize buggy lines and generate plausible patches which can pass all unit tests. The results show that while issue content is particularly effective in assisting LLMs with fault localization and program repair, different types of software artifacts complement each other. By incorporating different artifacts, DEVLoRe successfully locates 49.3% and 47.6% of single and non-single buggy methods and generates 56.0% and 14.5% plausible patches for the Defects4J v2.0 dataset, respectively. This outperforms current state-of-the-art APR methods.

However, seamless, coherent speech remains elusive, and clinical efficacy is still unproven. Here, we present an AI-driven intelligent throat (IT) system that integrates throat muscle vibrations and carotid pulse signal sensors with large language model (LLM) processing to enable fluent, emotionally expressive communication. The system utilizes ultrasensitive textile strain sensors to capture high-quality signals from the neck area and supports token-level processing for real-time, continuous speech decoding, enabling seamless, delay-free communication. In tests with five stroke patients with dysarthria, IT's LLM agents intelligently corrected token errors and enriched sentence-level emotional and logical coherence, achieving low error rates (4.2% word error rate, 2.9% sentence error rate) and a 55% increase in user satisfaction. This work establishes a portable, intuitive communication platform for patients with dysarthria with the potential to be applied broadly across different neurological conditions and in multi-language support systems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.18266v2-abstract-full').style.display = 'none';
