Allosteric regulation of the tyrosine phosphatase PTP1B by a protein-protein interaction

Posted by dbos Columbia, This Week: Neuroscience

Kavli Affiliate: Ann McDermott | Authors: Cassandra A Chartier, Virgil A Woods, Yunyao Xu, Anne E van Vlimmeren, Marko Jovanovic, Ann E McDermott, Daniel A Keedy and Neel H Shah | Summary: The rapid identification of protein-protein interactions has been significantly enabled by mass spectrometry (MS) proteomics-based methods, including affinity purification-MS, crosslinking-MS, and proximity-labeling proteomics. […]

Crunch from AdS bubble collapse in unbounded potentials

Posted by dbos This Week: Astrophysics, Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, , , | Summary: We consider a scalar field theory with a Minkowski false vacuum and an unbounded (or very deep) true vacuum. We show compelling evidence that an AdS bubble of vanishing total energy, embedded in asymptotically flat spacetime, generically undergoes […]

Real-time propagation of adaptive sampling selected configuration interaction wave function

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Avijit Shee, Zhen Huang, Martin Head-Gordon, K. Birgitta Whaley, | Summary: We have developed a new time propagation method, time-dependent adaptive sampling configuration interaction (TD-ASCI), to describe the dynamics of a strongly correlated system. We employ the short iterative Lanczos (SIL) method as the time-integrator, which provides […]

Two-dimensional room temperature ferromagnetic semiconductors

Posted by dbos This Week: Theoretical Physics, UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Jia-Wen Li, Gang Su, Bo Gu, , | Summary: To realize ferromagnetic semiconductors with high Curie temperature TC is still a challenge in spintronics. Recent experiments have obtained two-dimensional (2D) room temperature ferromagnetic metals, such as monolayers MnSe2 and Cr3Te6. In this paper, by the density functional […]

A halo model approach for mock catalogs of time-variable strong gravitational lenses

Posted by dbos Stanford, This Week: Astrophysics

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Katsuya T. Abe, Masamune Oguri, Simon Birrer, Narayan Khadka, Philip J. Marshall | Summary: Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadenced surveys, such as the LSST, […]
