Conditional expectations associated with quantum states
, 2010 An extension of the conditional expectations (those under a given subalgebra of events and not the simple ones under a single event) from the classical to the quantum case is presented. In the classical case, the conditional expectations always exist; in

Ecography, EarlyView.The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

SEMI – MARKOV MODEL OF THE FUNCTIONING PROCESS MEASURING INSTRUMENTS
Измерение, мониторинг, управление, контроль, 2022 Background. To substantiate the value of the interval between verifications and to calculate the performance indicators of functioning when measuring instruments (MI) are used for their intended purpose, various models of the functioning of the means ...

Perturbation theory for semi-Markov control problems [PDF]
, 1991 In earlier work, the authors considered the perturbation of systems undergoing Markov processes in which the times between two consecutive decision time points were equidistant.

European Eating Disorders Review, EarlyView.ABSTRACT Objective The early response effect, defined as a reliable symptomatic improvement during the initial phase of treatment, is the most robust predictor of recovery following eating disorder treatment. This study aimed to investigate which symptom domains mostly influence the early response effect. Methods Data from N = 232 adult patients (90.8%

Statistical estimation models for rail line reliability indicators
Transportation and Information Technologies in RussiaBackground. Conducting joints of rail lines are a critical element for the operation of railway automation and telemechanics devices. Their failures lead to malfunctions in track circuits, distorting information about train locations and creating safety ...

On Relationship between Ergodic Sojourn Time and Ergodic Residual Exit Time for Semi-Markov Processes [PDF]
, 2008 For Markov chains in continuous time Keilson(1979) has shown thatthe relationship between the ergodic exit time TE and the ergodic sojourn timeTV is identical to the relationship between the residual lifetime and the underlyinglifetime at ergodicity in ...

Comparison of Semi-Markov and Markov Processes
The Annals of Mathematical Statistics, 1971 Conditions are given under which a semi-Markov process $Z(t)$ can be obtained from a Markov process $Y(t)$ by a time change (i.e. $Z(t) = Y(\gamma(t))$). Estimates are given for $P\{\sup_{s\leqq t} |s - \gamma(s)| > \varepsilon\}$ and the construction is used to give conditions under which a sequence of semi-Markov processes will have the same ...
