We describe a stochastic model based on a branching process for analyzing surveillance data of infectious diseases that allows to make forecasts of the future development of the epidemic. The model is based on a Poisson branching process with immigration with additional adjustment for possible overdispersion. An extension to a longitudinal model for the multivariate case is described. The model...

Since 2002, the treatment of the branching ratios of the ψ(2S) and χc0,1,2 has undergone an important restructuring. When measuring a branching ratio experimentally, it is not always possible to normalize the number of events observed in the corresponding decay mode to the total number of particles produced. Therefore, the experimenters sometimes report the number of observed decays with respec...

We study the existence and some asymptotic properties of a conservative branching particle system for which birth and death are triggered by contact with a set. Sufficient conditions for the process to be non-explosive are given, solving a long standing open problem. With probability one, it is shown that only one ancestry survives. In special cases, the evolution of the surviving particle is s...

It has been shown that the size of myocardial infarction in rats created by coronary ligation technique is not uniform, varying from 4% to 65%. We hypothesized that infarct size variability induced by coronary artery ligation might be caused by coronary artery branching pattern. Coronary artery angiography was performed in 50 normal Lewis rats and in chronic myocardial infarction models in whic...

Background: It has been hypothesized that stable mother rotors may increase the stability of atrial fibrillation. Local shortening of action potential duration due to vagotonic activity may promote the formation of mother rotors. However, prior studies have shown that meandering rotors typically drift out of the region of short action potential duration (APD), making the formation of stable rot...

The short-finned eel ranavirus (SERV) was isolated from short-finned eel imported to Italy from New Zealand. Phylogenomic analyses revealed that SERV is a unique member of the genus Ranavirus, family Iridoviridae, branching at the base of the tree near other fish ranaviruses.

In the present study, influence of electron-beam irradiation on plasticity-controlled and crack-growth-controlled failure in high-density polyethylene (HDPE) is investigated effect both molecular weight distribution (MWD) short chain branching (SCB) content are taken into account. Size exclusion chromatography (SEC) used to study evolution MWD sol fraction as a function dose. Here, it seen that...

The radiative B → τ + τ − γ decay is investigated in the framework of the Standard Model. When only short (short and long together) distance contributions are taken into account, the Branching Ratio is found as 9.54 × 10 −9 (1.52 × 10 −8), for the value of the cut δ = 0.01 imposed on the photon energy.

We have succeeded in developing hollow branching structure in vitro commonly observed in lung airway using primary lung airway epithelial cells. Cell concentration gradient is the key factor that determines production of the branching cellular structures, as optimization of this component removes the need for heterotypic culture. The higher cell concentration leads to the more production of mor...

– The probability distribution P (k) of the sizes k of critical trees (branching ratio m = 1) is well known to show a power-law behavior k. Such behavior corresponds to the mean-field approximation for many critical and self-organized critical phenomena. Here we show numerically and analytically that also supercritical trees (branching ration m > 1) are ”critical” in that their size distributio...
