Influence of priors in Bayesian estimation of genetic parameters for multivariate threshold models using Gibbs sampling

open access: yesGenetics Selection Evolution, 2007
Simulated data were used to investigate the influence of the choice of priors on estimation of genetic parameters in multivariate threshold models using Gibbs sampling.

Rate‐Adaptive Site Transformation Catalyst for Parallel Water Dissociation and Hydrogen Adsorption in Alkaline Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Boltzmann-Gibbs Entropy to measure Fluctuation of Stock Index

open access: yesIndonesian Journal of Applied Physics
The disorder of a physical system can be measured based on the entropy of the system. The greater the entropy value of a system, the more disorder the system increases. In Physics, the disorder of system is measured by Boltzmann-Gibbs Entropy.

Existence of random gradient states

open access: yes, 2006
We consider two versions of random gradient models. In model A the interface feels a bulk term of random fields while in model B the disorder enters through the potential acting on the gradients. It is well known that for gradient models without disorder

Engineering Hydrogen‐Down Water Configurations for Ampere‐Level Electrochemical CO2 Reduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

Instrumental Variable Bayesian Model Averaging via Conditional Bayes Factors [PDF]

open access: yes, 2012
We develop a method to perform model averaging in two-stage linear regression systems subject to endogeneity. Our method extends an existing Gibbs sampler for instrumental variables to incorporate a component of model uncertainty.

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

open access: yesAdvanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Human tissue models in cancer research: looking beyond the mouse

open access: yesDisease Models & Mechanisms, 2017
Mouse models, including patient-derived xenograft mice, are widely used to address questions in cancer research. However, there are documented flaws in these models that can result in the misrepresentation of human tumour biology and limit the ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
