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: Zheng Zhu | First 5 Authors: Qi Zhang, Jiang Zhu, Fengzhong Qu, Zheng Zhu, De Wen Soh | Summary: Modulo sampling (MS) has been recently introduced to enhance the dynamic range of conventional ADCs by applying a modulo operator before sampling. This paper examines the identifiability of a measurement model where measurements are […]
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 […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yunqi Gu, Tao Zhou, Yizhe Zhang, Yi Zhou, Kelei He | Summary: Medical image segmentation plays a crucial role in computer-aided diagnosis. However, existing methods heavily rely on fully supervised training, which requires a large amount of labeled data with time-consuming pixel-wise annotations. Moreover, accurately segmenting lesions […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Bingzhi Liu, Yin Cao, Haohe Liu, Yi Zhou, | Summary: Diffusion models have demonstrated promising results in text-to-audio generation tasks. However, their practical usability is hindered by slow sampling speeds, limiting their applicability in high-throughput scenarios. To address this challenge, progressive distillation methods have been effective in […]
Kavli Affiliate: Bo Gu | First 5 Authors: Jia-Wen Li, Gang Su, Bo Gu, , | Summary: To realize room temperature ferromagnetic semiconductors is still a challenge in spintronics. Recent experiments have obtained two-dimensional (2D) room temperature ferromagnetic metals, such as monolayer MnSe2. In this paper, we proposed a way to obtain room temperature ferromagnetic […]
