An End-to-End Robust Point Cloud Semantic Segmentation Network with Single-Step Conditional Diffusion Models

Posted by dbos Peking, This Week: Astrophysics

Kavli Affiliate: Jing Wang | First 5 Authors: Wentao Qu, Jing Wang, YongShun Gong, Xiaoshui Huang, Liang Xiao | Summary: Existing conditional Denoising Diffusion Probabilistic Models (DDPMs) with a Noise-Conditional Framework (NCF) remain challenging for 3D scene understanding tasks, as the complex geometric details in scenes increase the difficulty of fitting the gradients of the […]

Charge-induced energy shift of a single-spin qubit under a magnetic-field gradient

Posted by dbos Delft, This Week: Nanoscience

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Takashi Kobayashi, Akito Noiri, Takashi Nakajima, Kenta Takeda, Leon C. Camenzind | Summary: An electron confined by a semiconductor quantum dot (QD) can be displaced by changes in electron occupations of surrounding QDs owing to the Coulomb interaction. For a single-spin qubit in an inhomogeneous magnetic field, […]

The fate of EMRI-IMRI pairs in AGN accretion disks: hydrodynamic and three body simulations

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Peng Peng, Alessia Franchini, Matteo Bonetti, Alberto Sesana, Xian Chen | Summary: Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs) are important gravitational wave (GW) sources for the Laser Interferometer Space Antenna (LISA). It has been recently suggested that EMRIs and IMRIs can both form in the accretion […]

A 44-minute periodic radio transient in a supernova remnant

Posted by dbos Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Di Li, Mao Yuan, Lin Wu, Jingye Yan, Xuning Lv | Summary: Long-period radio transients (LPTs) are a newly discovered class of radio emitters with yet incomprehensibly long rotation periods, ranging from minutes to hours. The astrophysical nature of their isolated counterparts remains undetermined. We report a […]

Strassen’s local law of the iterated logarithm for the generalized fractional Brownian motion

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: Let $X:={X(t)}_{tge0}$ be a generalized fractional Brownian motion: $$ {X(t)}_{tge0}overset{d}{=}left{ int_{mathbb R} left((t-u)_+^{alpha}-(-u)_+^{alpha} right) |u|^{-gamma/2} B(du) right}_{tge0}, $$ with parameters $gamma in (0, 1)$ and $alphain left(-1/2+ gamma/2, , 1/2+ gamma/2 right)$. This is a self-similar Gaussian process introduced […]

Magnon spintronics with Van der Waals magnets: from fundamentals to devices

Posted by dbos Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Samuel Mañas-Valero, Toeno van der Sar, Rembert A. Duine, Bart van Wees, | Summary: Spintronics is concerned with replacing charge current with current of spin, the electron’s intrinsic angular momentum. In magnetic insulators, spin currents are carried by magnons, the quanta of spin-wave excitations on […]

Morph: A Motion-free Physics Optimization Framework for Human Motion Generation

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Mingshuang Luo, Ruibing Hou, Xin Zhao, Hao Liu | Summary: Human motion generation plays a vital role in applications such as digital humans and humanoid robot control. However, most existing approaches disregard physics constraints, leading to the frequent production of physically implausible motions with pronounced […]

Bayesian inference of strangeon matter using the measurements of J0437-4751 and GW190814

Posted by dbos Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Wen-Li Yuan, Chun Huang, Chen Zhang, Enping Zhou, Renxin Xu | Summary: The observations of compact star inspirals from LIGO/Virgo combined with mass and radius measurements from NICER provide a valuable tool to study the highly uncertain equation of state (EOS) of dense matter at the densities […]
