Neural mechanisms underlying the effects of cognitive fatigue on physical effort-based decision-making Michael Dryzer and Vikram S. Chib

Posted by dbos Hopkins

Kavli Affiliate: Vikram Chib | Authors: Michael Dryzer and Vikram S. Chib | Summary: Fatigue is a state of exhaustion that influences our willingness to engage in effortful tasks. While both physical and cognitive exertion can cause fatigue, there is a limited understanding of how fatigue in one exertion domain (e.g., cognitive) affects decisions to […]

Dynamical evolution of massless particles in star clusters with NBODY6++GPU-MASSLESS: I. Free-floating MLPs

Posted by dbos Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Flammini Dotti, M. B. N. Kouwenhoven, Peter Berczik, Qi Shu, Rainer Spurzem | Summary: Context. Low-mass bodies, such as comets, asteroids, planetesimals, and free-floating planets, are continuously injected into the intra-cluster environment after expulsion from their host planetary systems. These can be modeled as massless particles […]

A mechanical quantum memory for microwave photons

Posted by dbos Caltech

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkım B. Bozkurt, Omid Golami, Yue Yu, Hao Tian, Mohammad Mirhosseini | Summary: Long-lived mechanical oscillators are actively pursued as critical resources for quantum storage, sensing, and transduction. However, achieving deterministic quantum control while limiting mechanical dissipation remains a persistent challenge. Here, we demonstrate strong coupling between […]

Extended red wings and the visibility of reionization-epoch Lyman-$α$ emitters

Posted by dbos Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Yuxuan Yuan, Sergio Martin-Alvarez, Martin G. Haehnelt, Thibault Garel, Laura Keating | Summary: The visibility of the Lyman-$alpha$ (Ly$alpha$) emission from reionization-epoch galaxies depends sensitively on the extent of the intrinsic lya emission redwards of 1215.67~AA. The prominent red peak resulting from resonant radiative transfer in the […]

NICER Spectral and Timing Analysis of 4U 1630$-$47 and its Heartbeat State

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Ningyue Fan, James F. Steiner, Cosimo Bambi, Erin Kara, Yuexin Zhang | Summary: We present a spectral and timing analysis of NICER observations of the black hole X-ray binary 4U 1630-47 from 2018 to 2024. We find relativistic reflection features in the hard and soft intermediate states, […]

MoDULA: Mixture of Domain-Specific and Universal LoRA for Multi-Task Learning

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Yufei Ma, Zihan Liang, Huangyu Dai, Ben Chen, Dehong Gao | Summary: The growing demand for larger-scale models in the development of textbf{L}arge textbf{L}anguage textbf{M}odels (LLMs) poses challenges for efficient training within limited computational resources. Traditional fine-tuning methods often exhibit instability in multi-task learning and rely heavily […]

Development of a bipolar 50 V output digital-to-analog converter system for ion-shuttling operations

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: T. Oshio, R. Nishimoto, T. Higuchi, K. Hayasaka, K. Koike | Summary: The quantum charge-coupled device (QCCD) is one of the notable architectures to achieve large-scale trapped-ion quantum computers. To realize QCCD architecture, ions must be transported quickly while minimizing motional excitation. High-voltage sources are necessary to […]
