A Stochastic Model of Active Cyber Defense Dynamics [PDF]
, 2016 The concept of active cyber defense has been proposed for years. However, there are no mathematical models for characterizing the effectiveness of active cyber defense.

Retrospective Higher-Order Markov Processes for User Trails
, 2017 Users form information trails as they browse the web, checkin with a geolocation, rate items, or consume media. A common problem is to predict what a user might do next for the purposes of guidance, recommendation, or prefetching.

Advanced Theory and Simulations, EarlyView.Binding energy and electronic structure calculations are used to assess the ability of metal–organic framework (MOF)‐TiO2 composite materials to detect volatile organic compounds found in human breath. Electronic structure changes are measured by comparing density of states profiles using Wasserstein distances.

Bayesian time‐varying autoregressive models of COVID‐19 epidemics
Biometrical Journal, Volume 65, Issue 1, January 2023., 2023 Abstract The COVID‐19 pandemic has highlighted the importance of reliable statistical models which, based on the available data, can provide accurate forecasts and impact analysis of alternative policy measures. Here we propose Bayesian time‐dependent Poisson autoregressive models that include time‐varying coefficients to estimate the effect of policy ...

Bayesian statistic methods and theri application in probabilistic simulation models
Farmeconomia: Health Economics and Therapeutic Pathways, 2007 Bayesian statistic methods are facing a rapidly growing level of interest and acceptance in the field of health economics. The reasons of this success are probably to be found on the theoretical fundaments of the discipline that make these techniques ...

Land use change modelling using a Markov model and remote sensing
, 2014 Land-use/land-cover (LU/LC) change is an important component of global environmental change. The need to understand LU/LC change is essential for regional development and land use management towards sustainable development.

Model checking for imprecise Markov chains. [PDF]
, 2013 We extend probabilistic computational tree logic for expressing properties of Markov chains to imprecise Markov chains, and provide an efficient algorithm for model checking of imprecise Markov chains.

Exact goodness-of-fit testing for the Ising model
, 2016 The Ising model is one of the simplest and most famous models of interacting systems. It was originally proposed to model ferromagnetic interactions in statistical physics and is now widely used to model spatial processes in many areas such as ecology ...

d'CARTESIAN, 2015 Hidden Markov Models (HMM) is a stochastic model and is essentially an extension of Markov Chain. In Hidden Markov Model (HMM) there are two types states: the observable states and the hidden states. The purpose of this research are to understand how hidden Markov model (HMM) and to understand how the solution of three basic problems on Hidden Markov ...

Advanced Science, EarlyView.A critical aspect of chromosomal remodeling in small molecule‐induced multilineage trans‐differentiation(iMT) is elucidated. A dynamic atlas spanning over 35 days profiles terminal trans‐differentiated cells, which reverted to a more youthful state. This study reveals parallels between iMT and other cell fate determination processes, emphasizing an ...
