Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Ao Huang, Satoshi Hattori, , | Summary: The summary receiver operating characteristic (SROC) curve has been recommended as one important meta-analytical summary to represent the accuracy of a diagnostic test in the presence of heterogeneous cutoff values. However, selective publication of diagnostic studies for meta-analysis […]

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Dapeng Yao, Mamoru Matsuo, Takehito Yokoyama, , | Summary: The recent experiment [R. Nakajima, et al., Nature 613, 479 (2023)] has reported a pair of oppositely polarized spins under an alternating electric current in a superconductor with a chiral structure. However, these behaviors cannot be explained by […]

Kavli Affiliate: Cheng Peng | First 5 Authors: Xue Cheng, Peng Guo, Tai-ho Wang, , | Summary: The paper addresses the problem of meta order execution from a broker-dealer’s point of view in Almgren-Chriss model under order fill uncertainty. A broker-dealer agency is authorized to execute an order of trading on client’s behalf. The strategies […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Zhouchen Deng, Shi Chen, Yiwei Qiu, Tianlei Zang | Summary: In a phase-locked loop (PLL) synchronized inverter, due to the strong nonlinear coupling between the PLL’s parame-ters and the operation power angle, the equivalent damping coefficient will quickly deteriorate while the power angle is close […]

Kavli Affiliate: Long Zhang | First 5 Authors: Xinrun Mi, Kunya Yang, Yuhan Gan, Long Zhang, Aifeng Wang | Summary: The interplay between lattice geometry, band topology and electronic correlations in the newly discovered kagome compounds AV$_3$Sb$_5$ (A=K, Rb, Cs) makes this family a novel playground to investigate emergent quantum phenomena, such as unconventional superconductivity, […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Qi Zhang, Jiang Zhu, Fengzhong Qu, Zheng Zhu, De Wen Soh | Summary: Unlimited sampling was recently introduced to deal with the clipping or saturation of measurements where a modulo operator is applied before sampling. In this paper, we investigate the identifiability of the model where measurements […]

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Shunichiro Kinoshita, Norihiro Tanahashi, Shin Nakamura, Mamoru Matsuo | Summary: We study nonequilibrium spin dynamics in differentially rotating systems, deriving an effective Hamiltonian for conduction electrons in the comoving frame. In contrast to conventional spin current generation mechanisms that require vorticity, our theory describes spins […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yiwei Chen, Yan Huang, Qingxin Li, Bingbing Tong, Guangli Kuang | Summary: The fractional quantum Hall (FQH) states are exotic quantum many-body phases whose elementary charged excitations are neither bosons nor fermions but anyons, obeying fractional braiding statistics. While most FQH states are believed to have Abelian […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Yunqi Gu, Tao Zhou, Yizhe Zhang, Yi Zhou, Kelei He | Summary: Automatic polyp segmentation plays a crucial role in the early diagnosis and treatment of colorectal cancer (CRC). However, existing methods heavily rely on fully supervised training, which requires a large amount of labeled data with […]
