The Impact of Population III.1 Flash Reionization for CMB Polarization and Thomson Scattering Optical Depth

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | Summary:The Population III.1 theory for supermassive black hole (SMBH) formation predicts a very early ($zsim20-25$), transient phase, “The Flash”, of cosmic reionization powered by supermassive stars that are SMBH progenitors. The universe then quickly recombined to become mostly neutral, with this state persisting until galaxies begin to reionize intergalactic gas […]

Restoring Pruned Large Language Models via Lost Component Compensation

Posted by klaurent Cornell

Kavli Affiliate: Kinfai Mak | First 5 Authors: Zijian Feng, Zijian Feng, , , | Summary: Pruning is a widely used technique to reduce the size and inference cost of large language models (LLMs), but it often causes performance degradation. To mitigate this, existing restoration methods typically employ parameter-efficient fine-tuning (PEFT), such as LoRA, to […]

GigaBrain-0: A World Model-Powered Vision-Language-Action Model

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: GigaBrain Team, GigaBrain Team, , , | Summary: Training Vision-Language-Action (VLA) models for generalist robots typically requires large-scale real-world robot data, which is expensive and time-consuming to collect. The inefficiency of physical data collection severely limits the scalability, and generalization capacity of current VLA systems. To address […]

Charge distribution of the gauge-mediation type Q ball

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:We numerically study the formation of the gauge-mediation type Q balls in the logarithmic square potential on three-dimensional lattices. We obtain the broad charge distribution of the Q ball of this type for the first time, to the best of our knowledge. The charge of the Q ball at the […]

Control of out-of-plane anti-damping spin torque with a canted ferromagnetic spin source

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom| First 5 Authors: Xiaoxi Huang, Xiaoxi Huang, , , | Summary:To achieve efficient anti-damping switching of nanoscale magnetic memories with perpendicular magnetic anisotropy using spin-orbit torque requires that the anti-damping spin-orbit torque have a strong out-of-plane component. The spin anomalous Hall effect and the planar Hall effect spin current produced by […]

Impartial Selection with Predictions

Posted by klaurent Berkeley

Kavli Affiliate: Felix Fischer | Summary:We study the selection of agents based on mutual nominations, a theoretical problem with many applications from committee selection to AI alignment. As agents both select and are selected, they may be incentivized to misrepresent their true opinion about the eligibility of others to influence their own chances of selection. […]
