Mapping the uncertainty of 19th century West African slave origins using a Markov decision process model [PDF]
arXiv, 2019 The advent of modern computers has added an increased emphasis on channeling computational power and statistical methods into digital humanities. Including increased statistical rigor in history poses unique challenges due to the inherent uncertainties of word-of-mouth and poorly recorded data.

Slave-particle quantization and sum rules in the t-J model [PDF]
, 1995 In the framework of constrained systems, we give the classical Hamiltonian formulation of slave-particle models and their correct quantization. The electron-momentum distribution function in the t-J and Hubbard models is then studied in the framework of slave-particle approaches and within the decoupling scheme.

On the number of genealogical ancestors tracing to the source groups of an admixed population [PDF]
arXiv, 2022 In genetically admixed populations, admixed individuals possess ancestry from multiple source groups. Studies of human genetic admixture frequently estimate ancestry components corresponding to fractions of individual genomes that trace to specific ancestral populations.

Advanced Intelligent Systems, EarlyView.A novel soft, wearable haptic device integrates pneumatic and electromagnetic actuators to improve tactile signal transmission. Optimized with finite elements method simulations, it accurately transmits high‐frequency (texture) and low‐frequency (shape) signals. Experimental validation shows its suitability for applications in master–slave robotics and
