Randomly Weighted Averages on Multivariate Dirichlet Distributions with Generalized Parameters

Revstat Statistical Journal
We study the distributional properties of the product of random stochastic matrices by using the Dirichlet distribution. Our observations widely generalize some known results on the randomly weighted averages about multivariate Dirichlet ...

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Hyperprior on symmetric Dirichlet distribution

CoRR, 2017
In this article we introduce how to put vague hyperprior on Dirichlet distribution, and we update the parameter of it by adaptive rejection sampling (ARS). Finally we analyze this hyperprior in an over-fitted mixture model by some synthetic experiments.

Charting Endocrine Progenitors Across Species and Organs

Advanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.

Comparative evaluation of alternative Bayesian semi-parametric spatial crash frequency models

Journal of Traffic and Transportation Engineering (English ed. Online)
Albeit with the notable benefits associated with Dirichlet crash frequency models and spatial ones, there is little research dedicated to exploring their combined advantages.

Anisotropic Memristive Switching in NbOCl2 Enabled by Directional Oxygen Ion Migration

Advanced Science, EarlyView.
This study investigates strongly orientation‐dependent memristive switching in anisotropic NbOCl2, observed exclusively along the in‐plane c‐axis. The switching originates from direction‐selective oxygen‐ion migration and vacancy propagation that modulate the Pd/NbOCl2 Schottky barrier, enabling short‐term plasticity.

Amorphous, Highly Conductive Pr0.7Ca0.3MnO3 for Area‐Dependent Resistive Switching AlOx Bilayer Devices

Advanced Electronic Materials, EarlyView.
High‐conductive amorphous Pr0.7Ca0.3MnO3 (PCMO) is explored as an alternative to polycrystalline PCMO for memristive heterostructures with back‐end‐of‐line compatibility, targeting neuromorphic hardware integration. Structural, electrical, and band alignment analyzes are correlated with the electrical characterization of area‐dependent resistive ...

Riemann zeta fractional derivative—functional equation and link with primes

Advances in Difference Equations, 2019
This paper outlines further properties concerning the fractional derivative of the Riemann ζ function. The functional equation, computed by the introduction of the Grünwald–Letnikov fractional derivative, is rewritten in a simplified form that reduces ...

Determinants of Knowledge and Usage of Generative Artificial Intelligence in Agricultural Extension: Evidence From Tennessee Extension Personnel

Agribusiness, EarlyView.
ABSTRACT This paper examines the determinants of generative AI (GenAI) knowledge and usage among agricultural extension professionals. Drawing on survey data from agricultural extension personnel in Tennessee, we employ regression analyses and latent Dirichlet allocation (LDA) for topic modeling of open‐ended responses to study the knowledge and usage ...
