Optimal dividends for a NatCat insurer in the presence of a climate tipping point

Canadian Journal of Statistics, EarlyView.
Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Self‐Similar Blowup for the Cubic Schrödinger Equation

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

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

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Social Comparison and Its Association With Disordered Eating Symptoms: A Systematic Review and Meta‐Analysis

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Social comparison has been widely implicated in the etiology and maintenance of body dissatisfaction and eating disorders. At the same time, however, the magnitude of this relationship remains unclear, with existing studies varying widely in methodology, measurement, and sample characteristics.

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Controlled Nanoarchitecture of Aligned Electrospinning Fiber Composite Electrolyte Based on Plant and Animal Biopolymers for Safe Na‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aligned Electrospun Composite Electrolyte. The resurgence of solid‐state Na+ battery, sustained through lithium deficiency and mounting costs, offers an auspicious alternative to solid‐state Li+ battery. This study introduces a nanoarchitectural approach that integrates electrospinning with a simple solution casting technique to develop a mechanically ...

Researching Attitude–Identity Dynamics to Understand Social Conflict and Change

European Journal of Social Psychology, EarlyView.
Abstract Societies undergo constant change, manifested in various ways such as technological developments, economic transitions, reorganization of cultural values and beliefs, or changes in social structures. Individuals play an active role in shaping social and societal change by interactively negotiating its manifestation.
