Integrating Time‐Adjusted Imaging Instability Into Functional Outcome Prediction After Intracerebral Hemorrhage: Development and Validation of the HAGIV Score

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early risk stratification may support clinical decision‐making in spontaneous intracerebral hemorrhage (ICH). We aimed to develop and internally validate HAGIV, a score integrating frequency of imaging markers (FIM), a time‐adjusted non‐contrast computed tomography (CT) metric of hematoma expansion, with established predictors for 90‐

Advancing Stroke Clinical Trials Using Community Engagement and Implementation Science Approaches

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Stroke clinical trials are essential for advancing stroke care but can face challenges with recruitment, retention, clinical relevance, and translation into real‐world practice. We propose that integrating community engagement and implementation science approaches into stroke trials can help address these needs.

Factors Associated With the Rising Trend in Self‐Reported Cognitive Disability Among U.S. Adults Aged 18–39 From 2013–2024

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Building on our prior Behavioral Risk Factor Surveillance System analysis identifying adults aged 18–39 as the primary driver of the national increase in self‐reported cognitive disability, we examined factors associated with this rise using 2013–2024 U.S. BRFSS data. Methods We analyzed U.S.

Continuity of Generalized Entropy

2020 IEEE International Symposium on Information Theory (ISIT), 2020
We study the continuity property of the generalized entropy as a functional of probability distribution, defined with an action space and a loss function. Upper and lower bounds for the entropy difference of two distributions are derived in terms of several commonly used f-divergences, the Wasserstein distance, and a distance that depends on the action

GENERAL ENTROPY OF GENERAL MEASURES

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2002
The concept of entropy is an important part of the theory of additive measures. In this paper, a definition of entropy is introduced for general (not necessarily additive) measures as the infinum of the Shannon entropies of "subordinate" additive measures. Several properties of the general entropy are discussed and proved.

On a Geometric Generalization of Entropy

Problems of Information Transmission, 2003
The geometrized entropy is introduced as a generalization of Shannon's entropy and some of its properties are studied.

ON GENERALIZED CUMULATIVE ENTROPIES

Probability in the Engineering and Informational Sciences, 2016
In the present paper, we introduce a generalization of the cumulative entropy proposed by Di Crescenzo and Longobardi [8]. This new notion is related to the lower records and the reversed relevation transform. Dynamic version of the newly proposed measure is considered.

Generalized entropies

Mathematical Notes, 1996
The purpose of this note is to study Renyi entropies from the ergodic theory viewpoint. Applications of the Renyi entropies to dynamical systems seem to have first appeared in the physical literature in order to define chaotic behaviour numerically. Here the authors present an elegant and mathematically rigorous approach to Renyi entropies.

A generalization of entropy equation: homogeneous entropies

Kybernetika, 1985
The general continuous, positively homogeneous (of degree \(\alpha\), \(\alpha >0)\) and symmetric solutions of the equation \[ H(x,y,z)- H(x+y,0,z) =G(x,y) \qquad (x\geq 0, y\geq 0, z\geq 0, xy+yz+zx>0) \] are determined by means of distributions (in the sense of Schwartz). The corresponding homogeneous entropies are defined and characterized.

Entropies, Generalized Entropies, Inequalities, and the Maximum Entropy Principle

1987
Different entropy concepts (increasingly general or particular depending on one’s point of view), the underlying knowledge (conditions, information) and inequalities associated to them are reviewed. Among the latter is the maximum entropy principle. It is proposed that entropies (in particular newly introduced ones) should be justified by showing that ...
