Stochastic Bifurcation Models

open access: yesThe Annals of Probability, 1999
We study an ordinary differential equation controlled by a stochastic process. We present results on existence and uniqueness of solutions, on associated local times (Trotter and Ray-Knight theorems), and on time and direction of bifurcation. A relationship with Lipschitz approximations to Brownian paths is also discussed.

Quantifying the consequences of nutritional strategies aimed at decreasing phosphorus excretion from pig populations: a modeling approach

open access: yesAnimal, 2016
There is a global imperative to reduce phosphorous (P) excretion from pig systems. In this study, a previously validated deterministic model was modified to be stochastic, in order to investigate the consequences of different management strategies on P ...

Mathematical Formulation of an Optimal Execution Problem with Uncertain Market Impact [PDF]

open access: yes, 2015
We study an optimal execution problem with uncertain market impact to derive a more realistic market model. We construct a discrete-time model as a value function for optimal execution.

Engineering Method for Calculating of an Axial Valve Separator With an External Location of the Locking Part

open access: yesFrontiers in Energy Research, 2020
The purpose of the work is to develop an analytical method for calculating the effective ranges of structural parameters of the throttle part of the axial valve with the external location of the locking shell based on the proposed stochastic models of ...

Fluctuations as stochastic deformation [PDF]

open access: yes, 2008
A notion of stochastic deformation is introduced and the corresponding algebraic deformation procedure is developed. This procedure is analogous to the deformation of an algebra of observables like deformation quantization, but for an imaginary ...

Antisense transcription‐dependent chromatin signature modulates sense transcript dynamics

open access: yesMolecular Systems Biology, 2018
Antisense transcription is widespread in genomes. Despite large differences in gene size and architecture, we find that yeast and human genes share a unique, antisense transcription‐associated chromatin signature.

Stochastic Frontier Models [PDF]

open access: yes, 2008
The stochastic frontier model was first proposed in the context of production function estimation to account for the effect of technical inefficiency. The inefficiency causes actual output to fall below the potential level (that is, the production frontier) and also raises production cost above the minimum level (that is, the cost frontier).

Risk Assessment of Human Consumption of Meat From Fenbendazole-Treated Pheasants

open access: yesFrontiers in Veterinary Science, 2021
Fenbendazole is a benzimidazole-class anthelmintic that is used for the control of immature and adult stages of internal parasites, such as nematodes and trematodes, in domestic food-animal species.
