The measurement of ionospheric absorption using extraterrestrial radio waves [PDF]
, 1957 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.

FEBS Letters, EarlyView.In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

The effect of surface heterogeneity on cloud absorption estimates [PDF]
, 2004 This study presents a systematic and quantitative analysis of the effect of inhomogeneous surface albedo on shortwave cloud absorption estimates. We used 3D radiative transfer modeling over a checkerboard surface albedo to calculate cloud absorption.

White mold detection in common beans through leaf reflectance spectroscopy [PDF]
Engenharia Agrícola, 2015 This study aimed to identify wavelengths based on leaf reflectance (400-1050 nm) to estimate white mold severity in common beans at different seasons. Two experiments were carried out, one during fall and another in winter.

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase
FEBS Letters, EarlyView.The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.

Damped Lyman-alpha Absorption Associated with an Early-Type Galaxy at Redshift z = 0.16377
, 1997 We report new HST and ground-based observations of a damped Lyman-alpha absorption system toward the QSO 0850+4400. The redshift of the absorption system is z = 0.163770 and the neutral hydrogen column density of the absorption system is log N = 19.81 cm*

Molecular Oncology, EarlyView.TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.

Synopsis of Mid-latitude Radio Wave Absorption in Europe [PDF]
, 1984 Radio wave absorption data covering almost two years from Europe to Central Asia are presented. They are normalized by relating them to a reference absorption. Every day these normalized data are fitted to a mathematical function of geographical location
