Bisimulation Relations Between Automata, Stochastic Differential Equations and Petri Nets [PDF]

, 2010
Two formal stochastic models are said to be bisimilar if their solutions as a stochastic process are probabilistically equivalent. Bisimilarity between two stochastic model formalisms means that the strengths of one stochastic model formalism can be used

A new smoothing modified three-term conjugate gradient method for l1 $l_{1}$-norm minimization problem

Journal of Inequalities and Applications, 2018
We consider a kind of nonsmooth optimization problems with l1 $l_{1}$-norm minimization, which has many applications in compressed sensing, signal reconstruction, and the related engineering problems.

Local linear approach: Conditional density estimate for functional and censored data

Demonstratio Mathematica, 2022
Let YY be a random real response, which is subject to right censoring by another random variable CC. In this paper, we study the nonparametric local linear estimation of the conditional density of a scalar response variable and when the covariable takes ...

Optimal Maintenance Policy for a Technical System Subject to Hidden Faults and Randomly Occurring Hazards [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2021
The paper presents a method of finding the optimal time between inspections for a system subject to degradation-related faults which make the system vulnerable to randomly occurring external hazards that may cause its damage.

Graph regularized non-negative matrix factorization with prior knowledge consistency constraint for drug–target interactions prediction

BMC Bioinformatics, 2022
Background Identifying drug–target interactions (DTIs) plays a key role in drug development. Traditional wet experiments to identify DTIs are expensive and time consuming. Effective computational methods to predict DTIs are useful to narrow the searching

A toolbox to demystify probabilistic and statistical paradoxes

Frontiers in Education, 2023
There is a variety of empirical evidence that the coverage of paradoxes in mathematics education helps to support thorough understanding of probabilistic and statistical concepts.

Stochastic gravity [PDF]

Physical Review D, 1997
Gravity is treated as a stochastic phenomenon based on fluctuations of the metric tensor of general relativity. By using a (3+1) slicing of spacetime, a Langevin equation for the dynamical conjugate momentum and a Fokker-Planck equation for its probability distribution are derived.

Stochastic desertification [PDF]

EPL (Europhysics Letters), 2014
The process of desertification is usually modeled as a first order transition, where a change of an external parameter (e.g. precipitation) leads to a catastrophic bifurcation followed by an ecological regime shift. However, vegetation elements like shrubs and trees undergo a stochastic birth-death process with an absorbing state; such a process ...
