Circumnuclear Dust in Luminous Early-Type Galaxies — I. Sample Properties and Stellar Luminosity Models

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jared R. Davidson, Benjamin D. Boizelle, Jonelle L. Walsh, Aaron J. Barth, Emma Rasmussen | Summary: Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of ETGs, Atacama Large Millimeter/sub-millimeter Array (ALMA) CO imaging and […]

Derivations of Bloch (Majorana–Bloch) equation, von Neumann equation, and Schrödinger–Pauli equation

Posted by dbos Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, , , , | Summary: The transition from classical physics to quantum mechanics has been mysterious. Here, we derive the space-independent von Neumann equation for electron spin mathematically from the classical Bloch or Majorana–Bloch equation, which is also derived. Subsequently, the space-independent Schr"odinger–Pauli […]

Mobius Assembly for Plant Systems uncovers combinatorial interactions among promoters, coding sequences, and terminators in gene regulation

Posted by dbos Hopkins

Kavli Affiliate: Andreas Andreou | Authors: Elif Gediz Kocaoglan, Andreas Andreou, Jessica Nirkko, Marisol Ochoa-Villarreal, Gary Loake and Naomi Nakayama | Summary: Plants are the primary biological platforms for producing food, energy, and materials in agriculture; however, they are largely untouched by synthetic biology-driven transformation in bioproduction technologies. Molecular tools for complex, multigene engineering are […]

Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, William McClymont, Nicolas Laporte, Guido Roberts-Borsani, Debora Sijacki | Summary: While JWST has observed galaxies assembling as early as $zsim14$, evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) — the descendants of these earliest galaxies — are few and […]

Information dynamics in decohered quantum memory with repeated syndrome measurements: a dual approach

Posted by dbos UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Jacob Hauser, Yimu Bao, Shengqi Sang, Ali Lavasani, Utkarsh Agrawal | Summary: Measurements can detect errors in a decohered quantum memory allowing active error correction to increase the memory time. Previous understanding of this mechanism has focused on evaluating the performance of error correction algorithms […]
