Axion minicluster power spectrum and mass function [PDF]

, 2017
When Peccei-Quinn (PQ) symmetry breaking happens after inflation, the axion field takes random values in causally disconnected regions. This leads to fluctuations of order one in the axion energy density around the QCD epoch.

The apo LETM1 F‐EF‐hand adopts a closed conformation that underlies a multi‐modal sensory role in mitochondria

FEBS Letters, EarlyView.
We present the first solution structure of the Ca2+‐depleted LETM1 F‐EF‐hand through a D676A/N678A Ca2+ binding‐deficient mutant, revealing a closed hydrophobic cleft caused by a unique F1‐helix pivot. The apo LETM1 F‐EF‐hand exhibits regiospecific hot and cold unfolding, sensitivity to physiological pH changes and potential for promiscuous heterotypic

Golgi-targeting viscosity probe for the diagnosis of Alzheimer’s disease

Scientific Reports
Early diagnosis and intervention of Alzheimer’s disease (AD) are particularly important to delay the pathological progression. Although fluorescent probes have been widely employed for investigating and diagnosing AD, their biological applications are ...

Bound Electron Enhanced Radiosensitisation of Nimorazole upon Charge Transfer

Molecules, 2022
This novel work reports nimorazole (NIMO) radiosensitizer reduction upon electron transfer in collisions with neutral potassium (K) atoms in the lab frame energy range of 10–400 eV.

A geometric model of gravitating mass formation and baryon mass spectrum [PDF]

Gravitation and Cosmology. 2001. V.7. N.1. P.1-6, 2020
The operator of elementary particle mass spectrum is constructed on the basis of the postulate of a six-dimensional space-time manifold having a Riemann-Cartan space structure, proceeding only from its geometric properties. Special solutions found for this operator well describe the mass spectrum of the known quark triplet and hence of some baryon ...

Universal Spectrum Identifier for mass spectra [PDF]

Nature Methods, 2020
AbstractMass spectra provide the ultimate evidence for supporting the findings of mass spectrometry (MS) proteomics studies in publications, and it is therefore crucial to be able to trace the conclusions back to the spectra. The Universal Spectrum Identifier (USI) provides a standardized mechanism for encoding a virtual path to any mass spectrum ...

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones

FEBS Letters, EarlyView.
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Drug Content Uniformity: Quantifying Loratadine in Tablets Using a Created Raman Excipient Spectrum

Pharmaceutics, 2021
Raman spectroscopy has proven valuable for determining the composition of manufactured drug products, as well as identifying counterfeit drugs. Here we present a simple method to determine the active pharmaceutical ingredient (API) mass percent in a ...

Determination of the Linear Mass Power Spectrum From the Mass Function of Galaxy Clusters [PDF]

Mon.Not.Roy.Astron.Soc. 337 (2002) 161, 2002
We develop a new method to determine the linear mass power spectrum using the mass function of galaxy clusters. We obtain the rms mass fluctuation sigma (M) using the expression for the mass function in the Press & Schechter (1974), Sheth, Mo & Tormen (2001) and Jenkins et al. (2001) formalisms. We apply different techniques to recover the adimensional

N* Mass Spectrum from an Anisotropic Action [PDF]

, 2000
Results are reported for N* masses in the 1/2+ and 1/2- sectors on an anisotropic lattice. The gauge action is the usual plaquette plus rectangle type, the quark action is of the D234 type, both having tadpole-improved tree-level coefficients.
