Changes in subjective acoustical indicators in halls with long and short reverberation times
Investigations of acoustics of halls of different types and volumes have disclosed good or acceptable values of the music sound clarity index C80, while the reverberation times of these halls were found to be either very short or very long. Subjectively,

A generalized inverse for graphs with absorption [PDF]
We consider weighted, directed graphs with a notion of absorption on the vertices, related to absorbing random walks on graphs. We define a generalized inverse of the graph Laplacian, called the absorption inverse, that reflects both the graph structure as well as the absorption rates on the vertices.

Detection of OH absorption against PSR B1849+00
We have searched for OH absorption against seven pulsars using the Arecibo telescope. In both OH mainlines (at 1665 and 1667 MHz), deep and narrow absorption features were detected toward PSR B1849+00. In addition, we have detected several absorption and

Mitochondria contain two mitoribosome rescue factors, ICT1 and MTRFR (C12orf65). ICT1 also functions as a mitoribosomal protein in mice and humans, and its loss is lethal. Although Mtrfr knockout mice could not be generated, knockout zebrafish lines for ict1 and mtrfr were established.

An analytical nonadiabatic approach has been developed to study the dimerization gap and the optical absorption coefficient of the Su-Schrieffer-Heeger model where the electrons interact with dispersive quantum phonons.

Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

The measurement of ionospheric absorption using extraterrestrial radio waves [PDF]
Introduction: The discovery by Jansky in 1932 of the presence of radio waves incident upon the earth from outer space has led to several new methods of studying the earth's upper atmosphere.

Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli
BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.
