Log-Determinant Divergences Revisited: Alpha-Beta and Gamma Log-Det Divergences
Entropy, 2015 This work reviews and extends a family of log-determinant (log-det) divergences for symmetric positive definite (SPD) matrices and discusses their fundamental properties.

British Journal of Clinical Psychology, Volume 65, Issue 2, Page 671-688, June 2026.Abstract Objectives A cohesive sense of self depends on intact autobiographical memory, both of which are impaired in dissociative disorders. Maladaptive daydreaming (MD), a recently proposed dissociative condition, involves excessive immersion in fantastical inner worlds, often at the expense of real‐life engagement, leading to distress and functional

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

European Journal of Neurology, Volume 33, Issue 6, June 2026.Presymptomatic genetic testing for genetic Creutzfeldt‐Jakob disease requires careful balancing of autonomy, psychological preparedness, and potential familial implications. Based on multidisciplinary experience in Israel, we propose a structured framework including pre‐test counseling, psychological appraisal, genetic testing, in‐person results ...

Isotopy and equivalence of knots in 3‐manifolds
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Two knots K$K$ and J$J$ in S3$S^3$ are isotopic if and only if they are related by an orientation‐preserving diffeomorphism of S3$S^3$. This claim follows from the fact that any orientation‐preserving self‐diffeomorphism of S3$S^3$ is isotopic to the identity. We show that this same idea applies to any prime oriented closed 3‐manifold.

Statistical Analysis of Distance Estimators with Density Differences and Density Ratios
Entropy, 2014 Estimating a discrepancy between two probability distributions from samples is an important task in statistics and machine learning. There are mainly two classes of discrepancy measures: distance measures based on the density difference, such as the Lp ...

General H-theorem and Entropies that Violate the Second Law
Entropy, 2014 H-theorem states that the entropy production is nonnegative and, therefore, the entropy of a closed system should monotonically change in time. In information processing, the entropy production is positive for random transformation of signals (the ...

On the Centroids of Symmetrized Bregman Divergences
CoRR, 2007 In this paper, we generalize the notions of centroids and barycenters to the broad class of information-theoretic distortion measures called Bregman divergences. Bregman divergences are versatile, and unify quadratic geometric distances with various statistical entropic measures.
