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

open access: yesFEBS 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

"Uniform Measures On Inverse Limit Spaces" [PDF]

open access: yes
Motivated by problems from dynamic economic models, we consider the problem of defining a uniform measure on inverse limit spaces. Let f be a function from a compact metric space X into itself where f is continuous, onto and piecewise one-to-one.

Adaptive wavelet estimations for the derivative of a density in GARCH-type model

open access: yesJournal of Inequalities and Applications, 2019
Recently, Rao investigated the estimations for the derivative of a density in GARCH-type model S=σ2Z $S=\sigma ^{2}Z$ over L2 $L^{2}$-risk (Commun. Stat., Theory Methods 46:2396–2410, 2017).

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

open access: yesFEBS 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

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

open access: yesFEBS 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 ...

Existence of competitive equilibrium in a single-sector growth model with heterogeneous agents and endogenous leisure [PDF]

open access: yes
We prove the existence of competitive equilibrium in a single-sector dynamic economy with heterogeneous agents and elastic labor supply. The method of proof relies on exploiting the existence of Lagrange multipliers in infinite dimensional spaces and the

The issue of carrier space and the spatial characteristics of Edo middle-lower samurai residences from a space syntax perspective: reinterpreting spatial evolution in modern Japanese urban housing

open access: yesJournal of Asian Architecture and Building Engineering
This study analyzes the spatial configuration of Edo middle-lower class samurai residences using space syntax theory, focusing on the relationship between internal and external spaces.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

A Model Category for Local Po-spaces [PDF]

open access: yes, 2006
Locally partial-ordered spaces (local po-spaces) have been used to model concurrent systems. We provide equivalences for these spaces by constructing a model category containing the category of local po-spaces.
