Axion-like Particle Effects on Photon Polarization in High-Energy Astrophysics

Universe
In this review, we present a self-contained introduction to axion-like particles (ALPs) with a particular focus on their effects on photon polarization: both theoretical and phenomenological aspects are discussed.

Innovation Diffusion Among Case‐Based Decision‐Makers

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes a model of innovation diffusion with case‐based individuals a la Gilboa and Schmeidler, who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion patterns change with individual characteristics, innovation characteristics,

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Models in Decision‐Making Under Risk and Uncertainty

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

Where Have All the Little Red Dots Gone? Supermassive Black Hole Binary Dynamics and Its Impact on Galaxy Properties

The Astrophysical Journal Letters
Recent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts z  ≳ 6, characterized by extremely high central stellar densities and overmassive central supermassive black holes (SMBHs), “little red dots” (LRDs). A

Women Directors and R&D Investment in Family Firms: The Mediating Role of Debt Financing

Journal of Product Innovation Management, EarlyView.
ABSTRACT Although research examining the role of women directors in fostering innovation within family firms continues to expand, the mechanisms underlying their influence remain insufficiently understood. This study examines the mediating role of debt financing in the relationship between women directors and R&D investment.

SN 2022oqm: A Bright and Multipeaked Calcium-rich Transient

The Astrophysical Journal
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multipeaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875.
