A probabilistic extension of UML statecharts: specification and verification [PDF]
, 2002 This paper is the extended technical report that corresponds to a published paper [14]. This paper introduces means to specify system randomness within UML statecharts, and to verify probabilistic temporal properties over such enhanced statecharts which ...

A Probabilistic Temporal Logic with Frequency Operators and Its Model Checking [PDF]
Electronic Proceedings in Theoretical Computer Science, 2011 Probabilistic Computation Tree Logic (PCTL) and Continuous Stochastic Logic (CSL) are often used to describe specifications of probabilistic properties for discrete time and continuous time, respectively.

A biased competition theory of cytotoxic T lymphocyte interaction with tumor nodules. [PDF]
PLoS ONE, 2015 The dynamics of the interaction between Cytotoxic T Lymphocytes (CTL) and tumor cells has been addressed in depth, in particular using numerical simulations.

Debugging of Markov Decision Processes (MDPs) Models [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 In model checking, a counterexample is considered as a valuable tool for debugging. In Probabilistic Model Checking (PMC), counterexample generation has a quantitative aspect. The counterexample in PMC is a set of paths in which a path formula holds, and

Qualitative Logics and Equivalences for Probabilistic Systems [PDF]
Logical Methods in Computer Science, 2009 We investigate logics and equivalence relations that capture the qualitative behavior of Markov Decision Processes (MDPs). We present Qualitative Randomized CTL (QRCTL): formulas of this logic can express the fact that certain temporal properties hold ...

Meditation effects within the hippocampal complex revealed by voxel-based morphometry and cytoarchitectonic probabilistic mapping. [PDF]
, 2013 Scientific studies addressing anatomical variations in meditators' brains have emerged rapidly over the last few years, where significant links are most frequently reported with respect to gray matter (GM).

Discrete-time rewards model-checked [PDF]
, 2003 This paper presents a model-checking approach for analyzing discrete-time Markov reward models. For this purpose, the temporal logic probabilistic CTL is extended with reward constraints.

Logic and model checking for hidden Markov models [PDF]
, 2005 The branching-time temporal logic PCTL* has been introduced to specify quantitative properties over probability systems, such as discrete-time Markov chains. Until now, however, no logics have been defined to specify properties over hidden Markov models (

Predicting progression of Alzheimer's disease using ordinal regression.
PLoS ONE, 2014 We propose a novel approach to predicting disease progression in Alzheimer's disease (AD)--multivariate ordinal regression--which inherently models the ordered nature of brain atrophy spanning normal aging (CTL) to mild cognitive impairment (MCI) to AD ...

A Markov Chain Model Checker [PDF]
, 2000 Markov chains are widely used in the context of performance and reliability evaluation of systems of various nature. Model checking of such chains with respect to a given (branching) temporal logic formula has been proposed for both the discrete [17,6 ...
