The Association Between Levels of Post‐Discharge Care Continuity and Long‐Term Treatment Adherence and Anxiety‐Depressive Symptoms in Myocardial Infarction Patients: A Retrospective Cohort Study [PDF]

Nursing Open
Background Post‐discharge care continuity represents a modifiable factor influencing outcomes in myocardial infarction survivors, yet its multidimensional relationship with treatment adherence and psychological morbidity remains underexplored.

Existence and Approximation of Densities of Chord Length- and Cross Section Area Distributions

Image Analysis and Stereology, 2023
In various stereological problems a n-dimensional convex body is intersected with an (n−1)-dimensional Isotropic Uniformly Random (IUR) hyperplane. In this paper the cumulative distribution function associated with the (n−1)-dimensional volume of such a ...

ABSOLUTELY CONTINUOUS COMPENSATORS [PDF]

International Journal of Theoretical and Applied Finance, 2011
We give sufficient conditions on the underlying filtration such that all totally inaccessible stopping times have compensators which are absolutely continuous. If a semimartingale, strong Markov process X has a representation as a solution of a stochastic differential equation driven by a Wiener process, Lebesgue measure, and a Poisson random measure ...

Coefficients of multiple Fourier-Haar series and variational modulus of continuity

Қарағанды университетінің хабаршысы. Математика сериясы, 2023
In this paper, we introduce the concept of a variational modulus of continuity for functions of several variables, give an estimate for the sum of the coefficients of a multiple Fourier-Haar series in terms of the variational modulus of continuity, and ...

Diagonal sections of copulas, multivariate conditional hazard rates and distributions of order statistics for minimally stable lifetimes

Dependence Modeling, 2021
As a motivating problem, we aim to study some special aspects of the marginal distributions of the order statistics for exchangeable and (more generally) for minimally stable non-negative random variables T1, ..., Tr. In any case, we assume that T1, ...,

Absolute Continuity of Fuzzy Measures and Convergence of Sequence of Measurable Functions

Mathematics, 2020
In this note, the convergence of the sum of two convergent sequences of measurable functions is studied by means of two types of absolute continuity of fuzzy measures, i.e., strong absolute continuity of Type I, and Type VI.

Delta-Convexity With Given Weights

Annales Mathematicae Silesianae, 2020
Some differentiability results from the paper of D.Ş. Marinescu & M. Monea [7] on delta-convex mappings, obtained for real functions, are extended for mappings with values in a normed linear space.
