Invariance principle for diffusions in random environment

open access: yesCondensed Matter Physics, 2008
We will show an invariance principle for the diffusive motion of a particle interacting with a random frozen configuration of infinitely many other particles in Rd.

Random Environment INAR Models of Higher Order

open access: yesRevstat Statistical Journal, 2019
Two different random environment INAR models of higher order, RrNGINARmax(p) and RrNGINAR1(p), are introduced. Both of them are of variable order, which is not a random variable.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Branching processes in random environment [PDF]

open access: yes, 2011
In der folgenden Arbeit werden Eigenschaften von Verzweigungsprozessen in zufälliger Umgebung (engl. branching processes in random environment, kurz BPREs) untersucht. Das Modell geht auf Smith (1969) und Athreya (1971) zurück. Ein BPRE ist ein einfaches

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.

Random walk on the range of random walk [PDF]

open access: yes
We study the random walk X on the range of a simple random walk on ℤ d in dimensions d≥4. When d≥5 we establish quenched and annealed scaling limits for the process X, which show that the intersections of the original simple random walk path are ...

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

Limiting behaviour of random spatial graphs and asymptotically homogeneous RWRE [PDF]

open access: yes, 2005
We consider several random spatial graphs of the nearest-neighbour type, including the k- nearest neighbours graph, the on-line nearest-neighbour graph, and the minimal directed spanning tree.

Performance Modeling of Cloud Systems by an Infinite-Server Queue Operating in Rarely Changing Random Environment

open access: yesFuture Internet
This paper considers a heterogeneous queuing system with an unlimited number of servers, where the parameters are determined by a random environment. A distinctive feature is that the parameters of the exponential distribution of the request processing ...
