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

Outer measure analysis of topological lattice properties

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
Let X be a set and ℒ a lattice of subsets of X such that ∅, X∈ℒ. A(ℒ) is the algebra generated by ℒ, M(ℒ) the set of nontrivial, finite, normegative, finitely additive measures on A(ℒ) and I(ℒ) those elements of M(ℒ) which just assume the values zero and

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

On maxitive integration [PDF]

open access: yes, 2013
The Shilkret integral is maxitive (i.e., the integral of a pointwise supremum of functions is the supremum of their integrals), but defined only for nonnegative functions.

Lattice separation, coseparation and regular measures

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Let X be an arbitrary non-empty set, and let ℒ, ℒ1, ℒ2 be lattices of subsets of X containing ϕ and X. 𝒜(ℒ) designates the algebra generated by ℒ and M(ℒ), these finite, non-trivial, non-negative finitely additive measures on 𝒜(ℒ).

Normal‐Appearing White Matter Injury Mediates Chronic Deep Venous Hypoxia and Disease Progression in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

On invariant finitely additive measures for automorphism groups acting on tori [PDF]

open access: yes, 1985
Consider the natural action of a subgroup H of GL(n, Z) on Tn. We relate the H-invariant finitely additive measures on (Tn, L) where L is the class of all Lebesgue measurable sets, to invariant subtori C such that the H-action on either C or Tn/C factors

Normal characterizations of lattices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Let X be an arbitrary nonempty set and ℒ a lattice of subsets of X such that ∅, X∈ℒ. Let 𝒜(ℒ) denote the algebra generated by ℒ and I(ℒ) denote those nontrivial, zero-one valued, finitely additive measures on 𝒜(ℒ).

Temporal Interference Stimulation of Centromedian‐Parafascicular Complex in Disorders of Consciousness: A Pilot Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Treatment of disorders of consciousness (DoC) remains a major clinical challenge, and noninvasive, targeted modulation of deep brain structures has emerged as a promising therapeutic strategy. We aimed to evaluate the feasibility/safety and preliminary effects of thalamic temporal interference stimulation (TIS) targeting centromedian‐

On regular and sigma-smooth two valued measures and lattice generated topologies

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
Let X be an abstract set and L a lattice of subsets of X. I(L) denotes the non-trivial zero one valued finitely additive measures on A(L), the algebra generated by L, and IR(L) those elements of I(L) that are L-regular. It is known that I(L)=IR(L) if and
