Bayesian clustering of multivariate extremes

Canadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Patient‐ and Clinician‐Related Factors Associated With the Reduction in Opioid Use Among Adults With Chronic Non‐Cancer Pain: A Systematic Review

Clinical Pharmacology &Therapeutics, EarlyView.
Despite known risks, opioids are widely used for chronic non‐cancer pain (CNCP). Clinical guidelines now recommend deprescribing, but factors predicting success are poorly understood. This systematic review aimed to identify clinician and patient factors associated with attaining successful opioid dose reduction or discontinuation in adults with CNCP ...

National Identity Meaning and Attitudes Toward War, Peace, and the Future of Ukraine

Conflict Resolution Quarterly, EarlyView.
ABSTRACT The link between attitudes and social identity is complex, influencing perceptions, motivations, and actions. Social psychological research mainly focused on the role of attitude in identity formation, particularly in the contexts of social movements and collective action.

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

A New Strategy to Design Reconfigurable Rivest–Shamir–Adleman (RSA) Accelerators

International Journal of Circuit Theory and Applications, EarlyView.
A reconfigurable FPGA‐based RSA accelerator is proposed using compression‐based modular multipliers combined with pseudomoduli arithmetic. The approach maps modular exponentiation to low‐cost arithmetic domains and applies a correction stage, achieving significant improvements in delay, operating frequency, and delay–area efficiency compared with ...
