The combinational structure of non-homogeneous Markov chains with countable states
International Journal of Mathematics and Mathematical Sciences, 1983 Let P(s,t) denote a non-homogeneous continuous parameter Markov chain with countable state space E and parameter space [a,b], −∞

Health Economics, EarlyView.ABSTRACT Economic evaluations carried out from a societal perspective ought to account for the opportunity cost of a range of resources, including those committed by care recipients. People's time is such a resource: it is limited, valuable and it has an opportunity cost that should be reflected in cost calculations.

Journal of Applied Philosophy, EarlyView.ABSTRACT Gender and race have received significant philosophical attention recently; they are the paradigm cases of social kinds in most philosophical accounts. I argue for the inclusion of caste as a social kind because it affects the lives of many people, and because it presents itself as an important test case for philosophers of social kinds.

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

Obesity, EarlyView.ABSTRACT Objective This study compared the efficacy of metabolic/bariatric surgery (MBS) and GLP‐1 receptor agonists (GLP‐1 RAs), including dual GLP‐1/GIP analogues, for weight and metabolic outcomes in adults with obesity. Methods A network meta‐analysis of randomized controlled trials compared MBS or GLP‐1 RAs versus lifestyle intervention in adults ...

A characterization of soluble groups in which normality is a transitive relation [PDF]
International Journal of Group Theory, 2017 A subgroup $X$ of a group $G$ is said to be an H-subgroup if NG(X) ∩ Xg ≤ X for each element $g$ belonging to $G$. In [M. Bianchi and e.a., On finite soluble groups in which normality is a transitive relation, J.

Reachability relations, transitive digraphs and groups
Ars Mathematica Contemporanea, 2014 In A. Malnic, D. Marusic, N. Seifter, P. Sparl and B. Zgrablic, Reachability relations in digraphs, Europ. J. Combin. 29 (2008), 1566–1581, it was shown that properties of digraphs such as growth, property Z , and number of ends are reflected by the properties of certain reachability relations defined on the vertices of the corresponding digraphs.

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics
Quarterly Journal of the Royal Meteorological Society, EarlyView.Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.
