The Effects of the Local Environment on a Compact Radio Interferometer I: Cross-coupling in the Tianlai Dish Pathfinder Array

Posted by dbos Chicago

Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]

Quantifying Interstellar Extinction at High Galactic Latitudes

Posted by klaurent Cambridge

Kavli Affiliate: Kaisey Mandel | Summary:A detailed map of the distribution of dust at high Galactic latitudes is essential for future cosmic microwave background (CMB) polarization experiments because the dust, while diffuse, remains a significant foreground in these regions. We develop a Bayesian model to identify a region of the Hertzsprung-Russell (HR) diagram suited to […]

Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]

Contexts facilitate dynamic value encoding in the mesolimbic dopamine system

Posted by dbos Hopkins

Kavli Affiliate: Patricia Janak | Authors: Kurt Michael Fraser, Val L Collins, Amy R Wolff, David J Ottenheimer, Kaisa N Bornhoft, Fiona Pat, Bridget J Chen, Patricia H Janak and Benjamin T Saunders | Summary: Adaptive behavior in a dynamic environment often requires rapid revaluation of stimuli that deviates from well-learned associations. The divergence between […]

Electric fields determine carbapenemase activity in class A β-lactamases

Posted by dbos Hopkins

Kavli Affiliate: Michael Beer | Authors: Hira Jabeen, Michael Beer, James Spencer, Marc W van der Kamp, H Adrian Bunzel and Adrian J Mulholland | Summary: MAntimicrobial resistance is a public health crisis. Limited understanding of the catalytic drivers in resistance-mediating enzymes such as β-lactamases hinders our ability to combat this crisis. Here, we dissect […]

Male-male interactions shape mate selection in Drosophila

Posted by dbos Rockefeller

Kavli Affiliate: Vanessa Ruta | Authors: Tom Hindmarsh Sten, Rufei Li, Florian Hollunder, Shadé Eleazer and Vanessa Ruta | Summary: Males of many species have evolved behavioral traits to both attract females and repel rivals. Here, we explore mate selection in Drosophila from both the male and female perspective to shed light on how these […]

Very Local Impact on the Spectrum of Cosmic-Ray Nuclei below 100 TeV

Posted by klaurent Stanford

Kavli Affiliate: Igor Moskalenko | Summary:Recent measurements of primary and secondary CR spectra, their arrival directions, and our improved knowledge of the magnetic field geometry around the heliosphere allow us to set a bound on the distance beyond which a puzzling 10-TeV “bump” and certain related spectral features emphcannot originate. The sharpness of the spectral […]
