On the extinction of Continuous State Branching Processes with catastrophes [PDF]
, 2013 We consider continuous state branching processes (CSBP) with additional multiplicative jumps modeling dramatic events in a random environment. These jumps are described by a L\'evy process with bounded variation paths.

Network-based analysis of a small Ebola outbreak
Mathematical Biosciences and Engineering, 2017 We present a method for estimating epidemic parameters in network-based stochastic epidemic models when the total number of infections is assumed to be small. We illustrate the method by reanalyzing the data from the 2014 Democratic Republic of the Congo

Continuous flows driving branching processes and their nonlinear evolution equations
Advances in Nonlinear Analysis, 2022 We consider on M(ℝd) (the set of all finite measures on ℝd) the evolution equation associated with the nonlinear operator F↦ΔF′+∑k⩾1bkFkF \mapsto \Delta F' + \sum\nolimits_{k \geqslant 1} b_k F^k , where F′ is the variational derivative of F and we show

Factorial moments of the critical Markov branching process with geometric reproduction of particles
Modern Stochastics: Theory and Applications, 2022 The factorial moments of any Markov branching process describe the behaviour of its probability generating function $F(t,s)$ in the neighbourhood of the point $s=1$.

Limit theorems for Markov processes indexed by continuous time Galton--Watson trees [PDF]
, 2011 We study the evolution of a particle system whose genealogy is given by a supercritical continuous time Galton--Watson tree. The particles move independently according to a Markov process and when a branching event occurs, the offspring locations depend ...

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

On thermodynamic states of the Ising model on scale-free graphs
Condensed Matter Physics, 2013 There is proposed a model of scale-free random graphs which are locally close to the uncorrelated complex random networks with divergent studied in, e.g., S. N. Dorogovtsev et al, Rev. Mod. Phys., 80, 1275 (2008). It is shown that the Ising model on the

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 ...

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 ...

Branching Bisimilarity Checking for PRS
, 2014 Recent studies reveal that branching bisimilarity is decidable for both nBPP (normed Basic Parallel Process) and nBPA (normed Basic Process Algebra).
