A Hierarchical Framework for explaining the Cosmic Ray Spectrum using Diffusive Shock Acceleration

Posted by klaurent Stanford

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Paul Simeon, Noémie Globus, Payel Mukhopadhyay, Enrico Peretti | Summary: The hypothesis that the entire cosmic ray spectrum, from $lesssim1,{rm GeV}$ to $gtrsim100,{rm EeV}$ energy, can be accounted for by diffusive shock acceleration on increasingly large scales is critically examined. Specifically, it is conjectured that […]

Ventromedial Prefrontal Cortex and Basolateral Amygdala Projections to Ventromedial Striatum Encode Active Avoidance Behavior

Posted by klaurent UCSF

Kavli Affiliate: Lisa Gunaydin | Authors: Teagan E Bullock and Lisa A. Gunaydin | Summary: Active avoidance is a fundamental defensive behavior, defined as performing a voluntary action to escape a noxious stimulus. Active avoidance serves as an adaptive response to threat, ensuring safety. In individuals with anxiety disorders and post-traumatic stress disorder, avoidance behavior […]

What can galaxy shapes tell us about physics beyond the standard model?

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Oliver H. E. Philcox, Morgane J. König, Stephon Alexander, David N. Spergel, | Summary: The shapes of galaxies trace scalar physics in the late-Universe through the large-scale gravitational potential. Are they also sensitive to higher-spin physics? We present a general study into the observational consequences of […]

Quasi-BPS categories for K3 surfaces

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We introduce and begin the study of quasi-BPS categories for K3 surfaces, which are a categorical version of the BPS cohomologies for K3 surfaces. We construct semiorthogonal decompositions of derived categories of coherent sheaves on moduli stacks of semistable […]

Topological K-theory of quasi-BPS categories of symmetric quivers with potential

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous work, we studied quasi-BPS categories (of symmetric quivers with potential, of preprojective algebras, of surfaces) and showed they have properties analogous to those of BPS invariants/ cohomologies. For example, quasi-BPS categories are used to formulate categorical analogues […]

Quasi-BPS categories for symmetric quivers with potential

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We study certain categories associated to symmetric quivers with potential, called quasi-BPS categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands […]
