Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States
ABSTRACT It is known that the attractive singular potential gives rise to the quantum collapse in the framework of the three‐dimensional (3D) linear Schrödinger equation. This article summarizes theoretical results which demonstrate suppression of the collapse caused by this sing...

Denitrative Cyanation of Nitroalkanes by Nucleophilic Substitution through Anion–Radical Coupling
Abstract We report a photocatalytic denitrative cyanation to directly convert nitroalkanes into nitriles under mild conditions. The reaction proceeds rapidly under blue LED irradiation and exhibits broad functional-group tolerance. Mechanistic investigations support an anion–radi...

Stringy Constraints on Modular Flavor Models
Abstract We investigate stringy constraints on moduli spaces in modular flavor models by analyzing moduli-dependent threshold corrections in heterotic string vacua. While moduli play a crucial role in determining the flavor structure of fermions predicted by modular flavor models...

Experimental and CFD investigation of heat transfer in high-power avionics equipment
Reliable thermal verification of high-power-density avionics is challenging because densely packed circuit boards and narrow cooling passages complicate detailed modeling and experimental validation. This study evaluates the thermal performance of an avionics enclosure using an i...

Complete strategy spaces reveal hidden pathways to cooperation
Understanding how cooperation emerges and persists is a central challenge in evolutionary game theory. However, models of communication often rely on restricted strategy sets, making it unclear whether omitted behaviours alter cooperation. Here, we study the complete deterministi...
