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 ...

Cuban scientific production on diabetes, 2000–2017: Peer-reviewed Publications, Collaboration and Impact

, 2019
INTRODUCTION The steadily increasing prevalence of diabetes globally has captured researchers’ attention. Cuban production of scientific articles on diabetes has not been studied from a bibliometric perspective. OBJECTIVE Characterize the production and

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Reliability and Quality of Complex Systems

Надежность и качество сложных систем
Background. Prolonged operation of gas pipeline shut-off valves leads to gradual wear of the sealing elements of ball valves and, as a result, to their leakiness.

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

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
