Branching processes in random environment

, 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

Problems in random walks in random environments

, 2011
Recent years have seen progress in the analysis of the heat kernel for certain reversible random walks in random environments. In particular the work of Barlow(2004) showed that the heat kernel for the random walk on the infinite component of ...

Erythropoietin modulates hepatic inflammation, glucose homeostasis, and soluble epoxide hydrolase and epoxides in high‐fat diet‐induced obese mice

FEBS Open Bio, EarlyView.
Erythropoietin administration suppresses hepatic soluble epoxide hydrolase (sEH) expression, leading to increased CYP‐derived epoxides. This is associated with a shift in hepatic macrophage polarization characterized by reduced M1 markers and increased M2 markers, along with reduced hepatic inflammation, suppressed hepatic lipogenesis, and attenuated ...

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

FEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

Formation of spatial vegetation patterns in heterogeneous environments.

PLoS ONE
Functioning of many resource-limited ecosystems is facilitated through spatial patterns. Patterns can indicate ecosystems productivity and resilience, but the interpretation of a pattern requires good understanding of its structure and underlying ...

On convergence of population processes in random environments to the stochastic heat equation with colored noise [PDF]

, 2002
We consider the stochastic heat equation with a multiplicative colored noise term on ℝ2 d ≥ 1 in dimensions greater or equal to one. First, we prove convergence of a branching particle system in a random environment, to the stochastic heat equation with ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Processes in space-time random environments

, 2022
Consideramos um passeio aleatório de média nula em Z^d a tempo contínuo num ambiente espaço-temporal em Z^d x R_+ dado por processos de nascimento e morte independentes e identicamente distribuídos; de modo que as taxas de salto do passeio, meio ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
