Impact of half-wave plate systematics on the measurement of CMB $B$-mode polarization

Posted by dbos Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Marta Monelli, Eiichiro Komatsu, Tommaso Ghigna, Tomotake Matsumura, Giampaolo Pisano | Summary: Polarization of the cosmic microwave background (CMB) can help probe the fundamental physics behind cosmic inflation via the measurement of primordial $B$ modes. As this requires exquisite control over instrumental systematics, some next-generation CMB experiments […]

Explicit Change Relation Learning for Change Detection in VHR Remote Sensing Images

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Dalong Zheng, Zebin Wu, Jia Liu, Chih-Cheng Hung, Zhihui Wei | Summary: Change detection has always been a concerned task in the interpretation of remote sensing images. It is essentially a unique binary classification task with two inputs, and there is a change relationship between these two […]

Detecting Dark Matter Induced Power in Quantum Devices

Posted by dbos Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: In the past few years, many mesoscale systems have been proposed as possible detectors of sub-GeV dark matter particles. In this work, we point out the feasibility of probing dark matter-nucleon scattering cross section using superconductor-based quantum […]

Engineered Secretory Immunoglobulin A provides insights on antibody-based effector mechanisms targeting Clostridiodes difficile

Posted by dbos Hopkins

Kavli Affiliate: Michael Miller | Authors: Sonya Kumar Bharathkar, Michael J. Miller and Beth M. Stadtmueller | Summary: Secretory (S) Immunoglobin (Ig) A is the predominant mucosal antibody, which mediates host interactions with commensal and pathogenic microbes, including Clostridioides difficile. SIgA adopts a polymeric IgA structure that is bound by secretory component (SC). Despite significance, […]

Speed of sound in methane under conditions of planetary interiors

Posted by dbos Stanford

Kavli Affiliate: Peter Graham | First 5 Authors: Thomas G. White, Hannah Poole, Emma E. McBride, Matthew Oliver, Adrien Descamps | Summary: We present direct observations of acoustic waves in warm dense matter. We analyze wave-number- and energy-resolved x-ray spectra taken from warm dense methane created by laser heating a cryogenic liquid jet. X-ray diffraction […]

Constraints on Dark Matter from Dynamical Heating of Stars in Ultrafaint Dwarfs. Part 1: MACHOs and Primordial Black Holes

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: We place limits on dark matter made up of compact objects significantly heavier than a solar mass, such as MACHOs or primordial black holes (PBHs). In galaxies, the gas of such objects is generally hotter than the […]
