Phylogeny of Tec Family Kinases: Identification of a Pre-Metazoan Origin of Btk, Bmx, Itk, Tec, Txk and the Btk Regulator SH3BP5 [PDF]

, 2008
It is generally considered mammals and birds have five Tec family kinases (TFKs): Btk, Bmx (also known as Etk), Itk, Tec, and Txk (also known as Rlk). Here, we discuss the domains and their functions and regulation in TFKs.

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Analysis of the altitudinal structure of Storm-enhanced density using Total Electron Content data of space-borne and ground-based GPS receivers

Antarctic Record, 2013
The altitudinal structure of Storm-enhanced density (SED) was studied using the Total Electron Content (TEC) data of the GPS receiver on the Gravity Recovery and Climate Experiment (GRACE) satellite and the ground-based GPS receivers.

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response

Advanced Science, EarlyView.
This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Local Variations of the Total Electron Content (TEC) of the Ionosphere as Measured in the North Caucasus Mountains

Вестник КРАУНЦ. Физико-математические науки, 2023
Состояние ионосферы является важным параметром характеризующим динамику Солнечно – Земных связей. Полное электронное содержание ионосферы (ПЭС) является одним из основных параметров её диагностики. Он измеряется по задержке радиосигналов со спутников системы ГНСС на пути до приёмников. Солнечное влияние на ионосферу имеет глобальный характер.

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

Advanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

On the short-term relationship between solar soft X-ray irradiances and equatorial total electron content (TEC) [PDF]

, 2006
[1] The relationship between total electron content (TEC) and the solar soft X-ray irradiances is presented. Three bands ( 2 - 7 nm, 6 - 19 nm, and 17 - 20 nm) of solar soft X-ray measurements from the Student Nitric Oxide Explorer (SNOE) satellite are ...
