Material and thermal properties of MgCl2 molten salt by ab initio and machine-learning molecular-dynamics simulations

We study the structural, thermophysical, and dynamical properties of molten MgCl2 over a wide temperature range using Ab Initio Molecular Dynamics (AIMD) and molecular dynamics simulations based on machine-learning interaction potentials (MLIPs). MLIPs can achieve near-AIMD accur...

Weaker Coherence, Weaker Reciprocity: Comparing the Semantic and Social Organization of Moltbook and Reddit

Large language models enable the creation of autonomous agents that interact in social environments, raising the question of whether agent-based platforms reproduce the organizational properties of human social networks. We compare Moltbook, a social network populated by AI agent...

Thermodynamic Description of Wealth Inequality in the World

According to the recent Wealth Thermalization Hypothesis (WTH), the wealth inequality in the world is described by the Rayleigh–Jeans (RJ) thermal distribution of interacting agents in a society with social stratification. In this concept, the wealth layers of society are associa...

Characterization of Anisotropic Optical Behavior in Phase‐Change Material Sb 2 Se 3

ABSTRACT Phase‐change materials with ultralow optical losses are enabling a new generation of reconfigurable photonic devices. Sb 2 Se 3 has emerged as a leading candidate owing to its negligible optical losses across the visible and infrared, yet how polycrystallinity translates...

Expanding the Neurological Phenotype of ZTTK Syndrome: A Case of Recurrent Acute Confusional Migraine

Acute confusional migraine (ACM) is an uncommon pediatric migraine variant characterized by transient confusion and agitation, nonspecific electroencephalographic changes, and normal bloodwork and neuroimaging. We present the first case of ACM in a child with Zhu-Tokita-Takenouch...
