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.

Xenogeneic, extracorporeal liver perfusion in primates improves the ratio of branched-chain amino acids to aromatic amino acids (Fischer's ratio) [PDF]

open access: yes, 1999
In fulminant hepatic failure (FHF), the development of hepatic encephalopathy is associated with grossly abnormal concentrations of plasma amino acids (PAA).

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.

Feedback Reliability Ratio of an Intrusion Detection System

open access: yesJournal of Information Security, 2012
The behavior and nature of attacks and threats to computer network systems have been evolving rapidly with the advances in computer security technology. At the same time however, computer criminals and other malicious elements find ways and methods to thwart such protective measures and find techniques of penetrating such secure systems.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Likelihood Ratio Derivative Estimators For Stochastic Systems [PDF]

open access: yes1989 Winter Simulation Conference Proceedings, 1989
This paper discusses Iikelihood--ratio--derivative estimation techniques for stochastic systems. After a brief review of the basic concepts, likelihood-ratio-derivative estimators are presented for the following classes of stochastic processes: time homogeneous discrete-time Markov chains, non-time-homogeneous discrete-time Markov chains, time ...

Public policy failures related to China ́s Wind Power Development

open access: yes, 2019
An anecdote about the failure of the Soviet economic system tells about a factory which were evaluated based on tons of nails produced – unsurprisingly the nails became heavy. China is currently hailed as the worlds primer wind power producer; however, a
