Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Mathematical modelling of forecasting the results of knowledge testing / Žinių tikrinimo rezultatų prognozės matematinis modeliavimas

open access: yesTechnological and Economic Development of Economy, 2008
In this paper a mathematical model for obtaining probability distribution of the knowledge testing results is proposed. Differences and similarities of this model and Item Response Theory (IRT) logistic model are discussed.

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.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

The search for a prime-generating function

open access: yes, 1974
The theory of prime numbers contains several questions that remained unanswered for more than two thousand years. From the time that the concept of prime numbers was first developed until the early twentieth century, mathematicians were unable to find a ...

Continued fraction representation of the generating function of Bernoulli polynomials

open access: yes, 2022
Continued fraction and quasi-reciprocal continued fraction expansions of the generating function of Bernoulli numbers have been obtained. The convergence and uniform convergence of continued fraction expansions have been proved.

Recurrence Formulas for Choulet Sequences

open access: yesMathematics
In this paper, we consider the so-called Choulet sequence an, n=0,1,2,3,… For any complex numbers a0,a1,k,l, it is defined by the formula an+1=∑j=0najan−j+k(n+1)+l for n=1,2,3,… We derive the recurrence formula of the form (n+1)an+∑j=15(uj+nvj)an−j=0 for
