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 dbos 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 | 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 objects on K3 surfaces, where each summand is a categorical Hall […]

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

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | Summary:In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important roles in categorical wall-crossing formulas. In this paper, we make the […]

Quasi-BPS categories for symmetric quivers with potential

Posted by klaurent Tokyo

Kavli Affiliate: 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 are categorical Hall products of quasi-BPS categories. These results generalize our […]
