Jul 15, 2019
The rapid development of fluorescent probes for monitoring target enzymes is still a great challenge owing to the lack of efficient ways to optimize a specific fluorophore. Herein, a practical two-dimensional strategy was...
Mechanisms of Choice in X-Chromosome Inactivation.
Early in development, placental and marsupial mammals harbouring at least two X chromosomes per nucleus are faced with a choice that affects the rest of their lives: which of those X chromosomes to transcriptionally inactivate....

Structural diversity and electronic properties of Cu(2)SnX(3) (X = S, Se)
The ternary semiconductors Cu(2)SnX(3) (X = S, Se) are found frequently as secondary phases in synthesized Cu(2)ZnSnS(4) and Cu(2)ZnSnSe(4) samples, but previous reports on their crystal structures and electronic band gaps are...

Multienergy X-ray detection is critical to effectively differentiate materials in a variety of diagnostic radiology and nondestructive testing applications. Silicon and selenium X-ray detectors are the most common for...
Criteria for Dynamical Timescale Mass Transfer of Metal-poor Intermediate-mass Stars
Abstract
The stability criteria of rapid mass transfer and common-envelope evolution are fundamental in binary star evolution. They determine the mass, mass ratio, and orbital...
Birefringent Anti-Resonant Hollow-Core Fiber
Stephanos Yerolatsitis, Riley Shurvinton, Peng Song, Yaping Zhang, Robert Francis-Jones, Kristina Rusimova
Sep 15, 2020
Hollow-core fibers have demonstrated record performance in applications such as high-power pulse delivery, quantum computing, and sensing. However, their routine use is yet to become reality. A major obstacle is the ability...
Searching for axion-like particles with X-ray polarimeters
X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction between photons and axion-like particles (ALPs)....
An Invariant Arginine in Common with MHC Class II Allows Extension at the C-Terminal End of Peptides Bound to Chicken MHC Class I.
