Lacunary Series and Strong Approximation

open access: yesEntropy
Strong approximation, introduced by Strassen (1964), is one of the most powerful methods to prove limit theorems in probability and statistics. In this paper we use strong approximation of lacunary series with conditionally independent sequences to prove

Redundancy of Exchangeable Estimators

open access: yesEntropy, 2014
Exchangeable random partition processes are the basis for Bayesian approaches to statistical inference in large alphabet settings. On the other hand, the notion of the pattern of a sequence provides an information-theoretic framework for data compression

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.

The concept of exchangeability in ensemble forecasting [PDF]

open access: yesNonlinear Processes in Geophysics, 2011
A set of random variables is exchangeable if its joint distribution function is invariant under permutation of the arguments. The concept of exchangeability is discussed, with a view towards potential application in evaluating ensemble forecasts.

An elementary analysis of ridge regression with random design

open access: yesComptes Rendus. Mathématique, 2022
In this note, we provide an elementary analysis of the prediction error of ridge regression with random design. The proof is short and self-contained. In particular, it bypasses the use of Rudelson’s deviation inequality for covariance matrices, through ...

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.

Maximum asymmetry of copulas revisited

open access: yesDependence Modeling, 2018
Motivated by the nice characterization of copulas A for which d∞(A, At) is maximal as established independently by Nelsen [11] and Klement & Mesiar [7], we study maximum asymmetry with respect to the conditioning-based metric D1 going back to Trutschnig [

METHODOLOGY OF DETERMINING THE SIZE AND EXCHANGEABILITY OF CONTAINERS AT TERMINALS

open access: yesPromet (Zagreb), 2012
The paper analyzes the methodology of determining thesize of containers and their exchangeability in a terminal. Thesize of containers affects the exchangeability as well as the averageusability of capacity and the lack of uniformity in the deliveryof ...

EXCHANGE RATE PROTECTION AND EXCHANGE RATE CONFLICT

open access: yesOxford Economic Papers, 1988
OUR PURPOSE is to investigate in a simple model the consequences of the adoption of "exchange rate protection" by two countries trading with each other. Although very simplified and stylized in the present treatment, we believe that our model can throw light on some questions of practical importance. The present system of exchange rate setting has come

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 ...
