Kavli Affiliate: Eiichiro Komatsu | Summary:The polarized light of the cosmic microwave background is sensitive to new physics that violates parity symmetry. For example, the interaction of photons with the fields of elusive dark matter and dark energy could cause a uniform rotation of the plane of linear polarization across the sky, an effect known […]
Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]
Kavli Affiliate: Long Zhang | First 5 Authors: Guangzi Feng, Guangzi Feng, , , | Summary: We report on a high-power mid-infrared femtosecond master oscillator power amplifier (MOPA) system, employing Cr:ZnS and Cr:ZnSe polycrystals with fine-tuned doping profiles. Based on the soft-aperture Kerr-lens mode-locking in the soliton regime, the seed oscillator generates ~40-fs pulses with […]
Kavli Affiliate: Anna Frebel | Summary:Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following their ejection from stars. In this work, we test the common assumption of instantaneous and homogeneous metal mixing during the formation of […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yinlong Bai, Yinlong Bai, , , | Summary: Recent advancements in 3D Gaussian Splatting (3DGS) have made a significant impact on rendering and reconstruction techniques. Current research predominantly focuses on improving rendering performance and reconstruction quality using high-performance desktop GPUs, largely overlooking applications for embedded platforms like […]
Kavli Affiliate: Gerbrand Ceder| Summary:Understanding the moisture stability of oxide Li-ion conductors is important for their practical applications in solid-state batteries. Unlike sulfide or halide conductors, oxide conductors generally better resist degradation when in contact with water, but can still undergo topotactic chLi+/chH+ exchange (LHX). Here, we combine density functional theory (DFT) calculations with a […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Yule Ma, Yule Ma, , , | Summary: Thermalization in isolated quantum systems is governed by the eigenstate thermalization hypothesis, while strong disorder can induce its breakdown via many-body localization. Here we show that disorder can also generate a narrow band of thermal eigenstates embedded in an […]
Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Recent interpretability methods have proposed to translate LLM internal representations into natural language descriptions using a second verbalizer LLM. This is intended to illuminate how the target model represents and operates on inputs. But do such activation verbalization approaches actually provide privileged […]
Kavli Affiliate: Robert Edwards | Authors: Vijini Mallawaarachchi, George Bouras, Ryan R. Wick, Susanna R. Grigson, Bhavya Papudeshi and Robert A. Edwards | Summary: Assembly graphs are a fundamental data structure used by genome and metagenome assemblers to represent sequences and their overlap information, facilitating the assembler to construct longer genomic fragments. Apart from their […]
Kavli Affiliate: Darcy Peterka and Michael Shadlen | Authors: Jia Shen, Nuttida Rungratsameetaweemana, Prayshita Sharma, Darcy S. Peterka, Herbert Zheng Wu and Michael N. Shadlen | Summary: Cognitive operations often require flexible implementation of stimulus–response contingencies, depending on context. We developed an olfactory task in which mice learned to associate a test odor with a […]
