The branch process of cosmic strings [PDF]
Journal of Mathematical Physics, 2000 In light of the φ-mapping method and the topological tensor current theory, the topological structure and the topological quantization of topological defects are obtained under the condition that Jacobian J(φ/v)≠0. When J(φ/v)=0, it is shown that there exists the crucial case of branch process.

Branching Processes - A General Concept
Latin American Journal of Probability and Mathematical Statistics, 2021 The paper has four goals. First, we want to generalize the classical concept of the branching property so that it becomes applicable for historical and genealogical processes (using the coding of genealogies by ($V$-marked) ultrametric measure spaces leading to state spaces $\mathbb{U}$ resp. $\mathbb{U}^V$).

Branching-stable point processes [PDF]
Electronic Journal of Probability, 2015 The notion of stability can be generalised to point processes by defining the scaling operation in a randomised way: scaling a configuration by $t$ corresponds to letting such a configuration evolve according to a Markov branching particle system for -$\log t$ time.

The total mass of super-Brownian motion upon exiting balls and Sheu's compact support condition [PDF]
, 2013 We study the total mass of a d-dimensional super-Brownian motion as it first exits an increasing sequence of balls. The process of the total mass is a time-inhomogeneous continuous-state branching process, where the increasing radii of the balls are ...

Dendritic cells steering antigen and leukocyte traffic in lymph nodes
FEBS Letters, EarlyView.Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Parton Branching Process with Supersymmetric Particles at LHC Energies [PDF]
EPJ Web of Conferences, 2019 A 2-step parton branching model is proposed to describe the potential presence of supersymmetric particles in multiplicity distributions. This model gives a reasonable description of the data obtained at 13TeV by the ATLAS Collaboration across the ...

Genealogy of catalytic branching models
, 2009 We consider catalytic branching populations. They consist of a catalyst population evolving according to a critical binary branching process in continuous time with a constant branching rate and a reactant population with a branching rate proportional to

FEBS Letters, Volume 599, Issue 7, Page 1055-1074, April 2025.Hermansky‐Pudlak syndrome type 1 (HPS‐1) is a rare, autosomal recessive disorder with poorly understood renal involvement. Urinary extracellular vesicle (uEV) proteomics and a novel Hps1 mouse model reveal mitochondrial abnormalities and lipid accumulation in HPS‐1 kidney proximal tubule cells. Serum ApoA1 correlates with kidney function in our patient

Network-level reproduction number and extinction threshold for vector-borne diseases
Mathematical Biosciences and Engineering, 2014 The basic reproduction number of deterministic models is an essential quantity to predict whether an epidemic will spread or not. Thresholds for disease extinction contribute crucial knowledge of disease control, elimination, and mitigation of ...

General branching processes conditioned on extinction are still branching processes [PDF]
Electronic Communications in Probability, 2008 It is well known that a simple, supercritical Bienayme-Galton-Watson process turns into a subcritical such process, if conditioned to die out. We prove that the corresponding holds true for general, multi-type branching, where child-bearing may occur at different ages, life span may depend upon reproduction, and the whole course of events is thus ...
