A Lemma on Continuous Functions [PDF]

open access: yesCanadian Mathematical Bulletin, 1960
The point of this note is to get a lemma which is useful in treating homotopy between paths in a topological space [1].As explained in the reference, two paths joining a given pair of points in a space E are homotopic if there exists a mapping F: I x I →E (I being the closed interval [0,1] ) which deforms one path continuously into the other.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Characteristic function estimation of Ornstein-Uhlenbeck-based stochastic volatility models. [PDF]

open access: yes
Continuous-time stochastic volatility models are becoming increasingly popular in finance because of their flexibility in accommodating most stylized facts of financial time series.

Symmetrically approximately continuous functions, consistent density theorems, and Fubini type inequalities [PDF]

open access: yes, 2005
Using the continuum hypothesis, Sierpinski constructed a non-measurable function f such that {h : f( x + h) not equal f(x - h)} is countable for every x: Clearly, such a function is symmetrically approximately continuous everywhere.Here we to show that ...

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

open access: yesFEBS 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 ...

Continuous Uniform Finite Time Stabilization of Planar Controllable Systems [PDF]

open access: yes, 2015
Continuous homogeneous controllers are utilized in a full state feedback setting for the uniform finite time stabilization of a perturbed double integrator in the presence of uniformly decaying piecewise continuous disturbances.

A Generalised Stock-Out Function for Continuous Production Variables

open access: yesPromet (Zagreb), 2012
This paper follows up a previous study for optimising a production-inventory system when external demand is stochastic.A modified stock-out function is presented to cover more generalsituation when cumulative production may be a continuousvariable ...

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

open access: yesFEBS 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.

A note on a semicontinuous and darboux continuous function [PDF]

open access: yes, 2015
Present alternate proof for a function that is zero almost every­where, not indentically zero, of Baire class 1 (and indeed upper semi-continuous), and Darboux ...
