CIBER 4th flight fluctuation analysis: Pseudo-power spectrum formalism, improved source masking and validation on mocks

Posted by dbos Caltech

Kavli Affiliate: James J. Bock | First 5 Authors: Richard M. Feder, James J. Bock, Yun-Ting Cheng, Asantha Cooray, Phillip M. Korngut | Summary: Precise, unbiased measurements of extragalactic background anisotropies require careful treatment of systematic effects in fluctuation-based, broad-band intensity mapping measurements. In this paper we detail improvements in methodology for the Cosmic Infrared […]

Phage defense and genome editing using novel retrons sourced from isolated environmental bacteria

Posted by dbos UCSF

Kavli Affiliate: Seth Shipman | Authors: Kazuo Nakamura, Karen Zhang, Mario R Mestre, Matias Rojas-Montero and Seth Shipman | Summary: Retrons are bacterial immune systems that protect a bacterial population against phages by killing infected hosts. Retrons typically comprise a reverse transcriptase, a template noncoding RNA that is partially reverse transcribed into RT-DNA, and a […]

Quantum oscillations in a dipolar excitonic insulator

Posted by dbos Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Bo Zou, Kenji Watanabe, Takashi Taniguchi | Summary: Quantum oscillations in magnetization or resistivity are a defining feature of metals subject to an external magnetic field. The phenomenon is generally not expected in insulators without a Fermi surface. The observations of quantum […]

Segmentation-Aware Generative Reinforcement Network (GRN) for Tissue Layer Segmentation in 3-D Ultrasound Images for Chronic Low-back Pain (cLBP) Assessment

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Zixue Zeng, Xiaoyan Zhao, Matthew Cartier, Tong Yu, Jing Wang | Summary: We introduce a novel segmentation-aware joint training framework called generative reinforcement network (GRN) that integrates segmentation loss feedback to optimize both image generation and segmentation performance in a single stage. An image enhancement technique called […]

Byzantine-Robust Federated Learning over Ring-All-Reduce Distributed Computing

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Minghong Fang, Zhuqing Liu, Xuecen Zhao, Jia Liu, | Summary: Federated learning (FL) has gained attention as a distributed learning paradigm for its data privacy benefits and accelerated convergence through parallel computation. Traditional FL relies on a server-client (SC) architecture, where a central server coordinates multiple clients […]

The impact of cosmic ray feedback during the epoch of reionisation

Posted by dbos Cambridge

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Marion Farcy, Joakim Rosdahl, Yohan Dubois, Jérémy Blaizot, Sergio Martin-Alvarez | Summary: Galaxies form and evolve via a multitude of complex physics. In this work, we investigate the role of cosmic ray (CR) feedback in galaxy evolution and reionisation, by examining its impact on the escape of […]

Phonon-mediated electron attraction in SrTiO$_3$ via the generalized Fröhlich and deformation potential mechanisms

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Norm M. Tubman, Christopher J. N. Coveney, Chih-En Hsu, Andres Montoya-Castillo, Marina R. Filip | Summary: Superconductivity in doped SrTiO$_3$ was discovered in 1964, the first superconducting transition observed in a doped semiconductor. However, the mechanism behind electron pairing in SrTiO$_3$ remains a subject of debate. […]
