RoboTransfer: Geometry-Consistent Video Diffusion for Robotic Visual Policy Transfer

Posted by dbos May 29, 2025June 9, 2025UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Liu Liu, Xiaofeng Wang, Guosheng Zhao, Keyu Li, Wenkang Qin | Summary: Imitation Learning has become a fundamental approach in robotic manipulation. However, collecting large-scale real-world robot demonstrations is prohibitively expensive. Simulators offer a cost-effective alternative, but the sim-to-real gap make it extremely challenging to scale. Therefore, […]

Theory of spin Seebeck effect activated by acoustic chiral phonons

Posted by klaurent May 29, 2025UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:We theoretically explore the generation of spin current driven by a temperature gradient in a junction between a chiral insulator and a normal metal. Based on the gyromagnetic response induced by microscopic acoustic-phonon-mediated lattice rotation, we derive a formula for the spin current when a finite temperature difference is imposed […]

DistMLIP: A Distributed Inference Platform for Machine Learning Interatomic Potentials

Posted by klaurent May 28, 2025Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:Large-scale atomistic simulations are essential to bridge computational materials and chemistry to realistic materials and drug discovery applications. In the past few years, rapid developments of machine learning interatomic potentials (MLIPs) have offered a solution to scale up quantum mechanical calculations. Parallelizing these interatomic potentials across multiple devices poses a challenging, […]

Population-level morphological analysis of paired CO2- and odor-sensing olfactory neurons in D. melanogaster via volume electron microscopy

Posted by dbos May 28, 2025June 9, 2025UCSD / Salk

Kavli Affiliate: Mark Ellisman | Authors: Jonathan Choy, Shadi Charara, Kalyani Cauwenberghs, Quintyn McKaughan, Keun-Young Kim, Mark Ellisman and Chih-Ying Su | Summary: Dendritic morphology is a defining characteristic of neuronal subtypes. In Drosophila, heterotypic olfactory receptor neurons (ORNs) expressing different receptors display diverse dendritic morphologies, but whether such diversity exists among homotypic ORNs remains […]

Spatiotemporal transcriptomic analysis during cold ischemic injury to the murine kidney reveals compartment-specific changes

Posted by dbos May 28, 2025June 9, 2025Hopkins

Kavli Affiliate: Jean Fan | Authors: Srujan Singh, Shishir Kumar Patel, Ryo Matsuura, Dee Velazquez, Zhaoli Sun, Sanjeev Noel, Hamid Rabb and Jean Fan | Summary: Kidney transplantation is the gold standard treatment strategy for end-stage renal disease. Deceased donor kidneys usually undergo cold storage until kidney transplantation, leading to cold ischemia injury that may […]

Optimized Theta Burst Stimulation with Extended Intervals Enhances Excitatory-Inhibitory Balance

Posted by dbos May 28, 2025June 9, 2025UCSD / Salk

Kavli Affiliate: Dhakshin Ramanathan and Jyoti Mishra | Authors: Morteza Salimi, Milad Nazari, Jonathan Mishler, Jennifer Rodger, Sahar Jomehpour, Jyoti Mishra and Dhakshin Ramanathan | Summary: Varying inter-train intervals (ITIs) during theta burst stimulation (TBS) differentially modulates neuronal activity in the medial prefrontal cortex. Short ITIs (e.g., ITI 4 s) induce strong glutamatergic excitation but […]

Sequential transcriptional gates in the thalamo-cortical circuit coordinate memory stabilization

Posted by dbos May 28, 2025June 9, 2025Rockefeller

Kavli Affiliate: Priya Rajasethupathy | Authors: Andrea Terceros, Celine Chen, Yujin Harada, Tim Eilers, Millennium Gebremedhin, Richard P Koche, Pierre-Jacques Hamard, Roshan Sharma and Priya Rajasethupathy | Summary: The molecular mechanisms that enable memories to persist over long time-scales from days to weeks and months are still poorly understood. To develop insights we created a […]

VidText: Towards Comprehensive Evaluation for Video Text Understanding

Posted by klaurent May 28, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Zhoufaran Yang, Zhoufaran Yang, , , | Summary: Visual texts embedded in videos carry rich semantic information, which is crucial for both holistic video understanding and fine-grained reasoning about local human actions. However, existing video understanding benchmarks largely overlook textual information, while OCR-specific benchmarks are constrained to […]

Basic Elements of Strong Gravitational Lensing

Posted by klaurent May 28, 2025MIT

Kavli Affiliate: Paul Schechter | Summary:Even when used to describe the same phenomenon, equations, graphics and words each give different perspectives and lead to complementary insights. The basic elements of strong gravitational lensing are introduced here favoring words and graphics over equations whenever possible. Fermat’s principle is the fundamental driver of strong lensing. Three "D’s” […]
