From Electronic Heterogeneity to Extreme Residence Times: A Multiscale Model of Energetic Stabilization, Stochastic Trapping, and Transport

Persistent local states can arise without a uniform reduction in system-wide mobility.Here, we develop a minimal multiscale model to examine whether mi-croscopic electronic heterogeneity can propagate through energetic stabi-lization into extreme local residence-time statistics.A four-state effective Hamiltonian was us...

Robotic Hand‐Arm Coordinated Skill Learning for Tool Manipulation Tasks

ABSTRACT This paper focuses on the specific scenario of tool manipulation and presents a novel framework enabling robots to acquire tool manipulation skills through learning from human demonstrations. While there have been numerous studies on robotic manipulation skill learning, most of them fail to fully leverage the...

Identifiable Transport Groups and Bayesian Experimental Design in Finite Bath Dyeing

Finite bath dyeing models can fit trajectories precisely while obscuring geometric ambiguity and binding error. We derive a conservative diffusion–binding model with uncertain thickness, pore volume, film transfer and optical scale. An exact scaling symmetry identifies Dref/L² and kf/L as observable transport groups. A...

Review of: "AVID: Adapting Video Diffusion Models to World Models"

Renewable Energy Explained: Power Systems, Storage & Sustainable Technologies

Renewable Energy Explained: Power Systems, Storage & Sustainable Technologies is a publication-grade Open Educational Resource (OER) module covering the thermodynamic principles, electrochemical modeling, conversion technologies, and grid integration of sustainable power systems. Serving as an integral core module with...

Poisson Spacetime Discreteness and Unimodular Gravity: Consistency Conditions and Exact Past-Cone Statistics of a Fluctuating Cosmological Term in the TSGT Framework

Abstract Can Poisson discreteness of spacetime supply gravitational dynamics or a fluctuating cosmological term? We examine this question for the framework previously called Topological String-Gradient Theory (TSGT) and then make its statistical proposal quantitative. A random counting measure, its metric-dependent mea...

Digital Transformation in Banking and Financial Performance of Commercial Banks in Uasin Gishu County, Kenya.

Digital banking adoption refers to the integration and use of electronic platforms such as mobile banking, internet banking, agency banking and automated teller machines (ATMs) to deliver financial services. It is increasingly regarded as a critical driver of efficiency, service delivery and financial performance in th...

A Low-Latency Multi-Agent Architecture for Statistical Arbitrage, Market Making, and Volatility-Conditioned Leverage Scaling Across Asset Classes

This institutional research memorandum presents the architecture, theoretical design, and empirical evaluation of a systematic, multi-asset intraday trading system designed for statistical arbitrage and market making across cryptocurrency perpetual derivatives, equity index derivatives, and CME futures. The system comb...

MOSAIC: Learning Graph Node Embeddings from Spectrally Isolated Dominant Subspaces of Accumulated Diffusion Operators

Biomedical knowledge graphs can connect information across genes, phenotypes, tissues, pathways, experiments, and clinical resources, but they are difficult to query correctly without detailed knowledge of the graph. Large language models can help write Cypher code for knowledge graphs, yet a query focused on a bioinfo...

الانكليزية كرمز للمكانة: تحليل نقدي لخطاب استخدام اللغة الانكليزية في القنوات الفضائية العراقية

Since 2003, Iraqi satellite television has been one of the public spheres where English is spoken, displayed and performed, and at the moment, many Iraqi channels broadcast talk shows, entertainment programs, morning shows and lifestyle programs where presenters and guests use English words and phrases as part of their...

Replication Data and Python Code for: Pathwise Concentration in Regime-Switching Fractional Diffusions

This repository contains the S&P 500 dataset (n=4{,}211 daily logarithmic returns) and Python code used to empirically motivate the regime-switching framework in the associated manuscript. The code implements the scaled forward--backward EM algorithm to fit a two-state Gaussian hidden Markov model, generating maximum l...
