Variable Coupling Scheme for High-Frequency Electron Spin Resonance Resonators Using Asymmetric Meshes
TL;DR: This work reports on a novel asymmetric mesh structure that achieves continuously variable coupling by rotating the mesh in its own plane about the millimeter-wave transmission-line optical axis and quantifies the performance of this device with nitroxide spin label spectra in both a lossy aqueous solution and a low-loss solid-state system.

A cryostat for investigating spin polarized hydrogen
TL;DR: A low temperature spin polarized hydrogen apparatus is discussed in this article, where fluxes into the hydrogen cell of 10 14 atoms/sec have been achieved and hydrogen atom concentrations of 1 × 10 16 atoms/cm 3 have been observed in fields of 9 Tesla and at 06 K, as determined by strain gauge measurements and calorimetric methods

SARS-CoV-2 Fusion Peptide has a Greater Membrane Perturbating Effect than SARS-CoV with Highly Specific Dependence on Ca2+
Alex L. Lai,Jack H. Freed +1 more
TL;DR: In this paper, the authors used sequence alignment to identify the SARS-2 fusion peptide and studied its membrane ordering effect, which showed that Ca2+ is an important regulator that interacts with the Sars-2 FP and thus plays a significant role in SARS2 viral entry.
