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

STRUCTURAL PROBLEMS IN MECHANISMS THAT GENERATES POLYSOMAL CURVES

Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2018
It defines the polysomal curves based on literature data and presents some mechanisms that generate such curves given in [1]. These mechanisms are constructed on the basis of geometric properties, their analysis being simple as geometric particular cases.

Potential Impacts of Subprime Carbon on Australia’s Impending Carbon Market [PDF]

This paper examines the potential impacts of subprime carbon credits on the impending Australian carbon market. Subprime carbon could potentially be created in carbon offset markets that lack adequate regulation, as projects face risks that can overstate

Enhancement of Synchronization in a Hybrid Neural Circuit by Spike-Timing Dependent Plasticity

, 2003
Synchronization of neural activity is fundamental for many functions of the brain. We demonstrate that spike-timing dependent plasticity (STDP) enhances synchronization (entrainment) in a hybrid circuit composed of a spike generator, a dynamic clamp ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

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 ...

GENERATION MECHANISM OF RAIL CORRUGATION AT CURVED TRACKS HAVING SHORT RADIUS

Doboku Gakkai Ronbunshu, 1991
Rail corrugation is one of the most serious problems of modern railway tracks, which may cause prompt destruction of tracks. This paper presents theoretically a generation mechanism of rail corrugation at curved tracks having short radius based on rolling-slipping dynamics of running wheels.
