Sharp interfaces in p+-AlGaAs/n-GaAs epitaxial structures obtained by MOCVD

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014
The complexity of forming sharp and high-quality boundaries in p+AlGaAs/n-GaAs systems by MOCVD method is caused by differing on 80–120°С optimal crystallization temperature of GaAs layers and n-AlGaAs solid solutions.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Features of designing internal power supply circuits for micropower ICs based on injection logic elements

Технологія та конструювання в електронній апаратурі, 2008
Control of the ohmic resistance of “hidden layers” of the n+-type using a mathematical model based on an elementary cell of equivalent lumped conductance with partitioning along two coordinates makes it possible to significantly reduce the variation of ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

FEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Curcuit-design solutions for producing devices of feed water flow rate control systems

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
Creation of a low-noise water flow control systems apparatus is the main objective of the research. The technique of carrying out the tests is based on the principles of acoustics, flow mechanics and the control theory. The main schemes of regulating the

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
