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, […]

Modeling Extensive Defects in Metals through Active Machine Learning and Automated Configuration Reconstruction

Posted by dbos Caltech, This Week: Nanoscience

Kavli Affiliate: Wei Gao | First 5 Authors: Fei Shuang, Kai Liu, Yucheng Ji, Wei Gao, Luca Laurenti | Summary: Extended defects such as dislocation networks and complex grain boundaries are ubiquitous in metals, and accurately modeling these extensive defects is crucial for understanding their deformation mechanisms. Existing machine learning interatomic potentials (MLIPs) often fall […]

Quantum Metrology for Gravitational Wave Astronomy

Posted by dbos MIT, This Week: Astrophysics

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Roman Schnabel, Nergis Mavalvala, David E. McClelland, Ping Koy Lam, | Summary: Einstein’s General Theory of Relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves have not been directly detected to date, but are expected to open […]

PICZL: Image-based Photometric Redshifts for AGN

Posted by dbos Peking, This Week: Astrophysics

Kavli Affiliate: Claudio Ricci | First 5 Authors: William Roster, Mara Salvato, Sven Krippendorf, Aman Saxena, Raphael Shirley | Summary: Computing photo-z for AGN is challenging, primarily due to the interplay of relative emissions associated with the SMBH and its host galaxy. SED fitting methods, effective in pencil-beam surveys, face limitations in all-sky surveys with […]
