Asymptotic behaviour near extinction of continuous state branching processes [PDF]
arXiv, 2013 In this note, we study the asymptotic behaviour near extinction of (sub-) critical continuous state branching processes. In particular, we establish an analogue of Khintchin's law of the iterated logarithm near extinction time for a continuous state branching process whose branching mechanism satisfies a given condition and its reflected process at its

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

STUDY ON THE CRACK BRANCHING BEHAVIOR DURING CRACK PROPAGATION INFLUENCED BY CONSTRAINT
Jixie qiangdu, 2022 During the crack propagation process, the crack branching behavior makes fracture more unpredictable. In this work, three kinds of crack branching models were selected, and the FEM simulations based on GTN（Gurson-Tvergaard-Needleman） damage model were ...

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023 Background. When studying mathematical models of physical processes described by nonlinear equations with a parameter, situations are identified when the parameter reaches a certain critical value, which leads to a violation of unambiguity in the ...

A functional CLT for the occupation time of a state-dependent branching random walk
, 2007 We show that the centred occupation time process of the origin of a system of critical binary branching random walks in dimension $d\ge 3$, started off either from a Poisson field or in equilibrium, when suitably normalized, converges to a Brownian ...

Progressive Myoclonus Epilepsy: Distinctive MRI Changes in Cerebellar and Motor Networks
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Progressive myoclonus epilepsy (PME) is a rare generalized epilepsy syndrome with a well‐characterized genetic basis. The brain networks that are affected to give rise to the distinctive symptoms of PME are less well understood. Methods Eleven individuals with PME with a confirmed genetic diagnosis and 22 controls were studied.
