Study of de-aggregation of mechanochemically synthesized ZnSe nanoparticles by re-milling in the presence of ZnCl2 solution [PDF]

Acta Montanistica Slovaca, 2013
Conventional mechanochemical synthesis of zinc selenide, ZnSe nanoparticles was performed in a planetary ball mill by high-energy milling of zinc (Zn) and selenium (Se) powders. Mechanochemically synthesized ZnSe was subsequently re-milled in circulation

Gamma rays in L-B coordinates at CORONAS-I altitude [PDF]

Annales Geophysicae, 2005
We present here observations of gamma rays in the energy range between 3.0 and 8.3 MeV gathered by the SONG instrument aboard low-altitude polar-orbiting satellite CORONAS-I throughout the period March-June 1994.

Influence of rootstocks for Sangiovese vineyards in a high-altitude region of Santa Catarina State, Brazil: Impact on sensory and quality characteristics of wines

Semina: Ciências Agrárias, 2023
Adapting grape varieties to new viticultural regions requires studying the influence of rootstock on wine quality. This study aimed to identify rootstocks that most enhance the enological characteristics of grapes of the Sangiovese variety grown in the ...

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

Canadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Improving Genotype Imputation in High‐Dimensional Pharmacogenomics Using Multiple Imputation: Evaluation with Machine Learning Approaches

Clinical Pharmacology &Therapeutics, EarlyView.
Multiple imputation is well‐established for handling missing data, yet its use in high‐dimensional genetic datasets remains limited. Using pharmacokinetic tuberculosis simulations and SNP data (1000 Genomes Project), we compared machine learning (ML) and traditional approaches (e.g., mean imputation and complete‐case analysis) for imputation and ...

Validity and Reliability of the Self-Administered Timed Up and Go Test in Assessing Fall Risk in Community-Dwelling Older Adults

Geriatrics
Objectives: This study aimed to evaluate the validity and reliability of the self-administered Timed Up and Go (TUG) test—a gold standard for fall risk screening—by comparing it to the traditional face-to-face assessment conducted by a physiotherapist ...

A Redox‐Buffering System for Stabilizing the Lattice Oxygen Mechanism in CeO2/FeOOH Heterostructure Electrocatalysts for Highly Stable Anion Exchange Membrane Water Electrolyzers

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The CeO2/FeOOH heterostructure catalyst was synthesized via a facile co‐precipitation strategy. The work‐function disparity between CeO2 and FeOOH drives interfacial electron redistribution, thereby optimizing the OER pathway. Moreover, the interfacial Ce3+/Ce4+ couple establishes a “redox‐buffering system” that suppresses Fe dissolution and enhances ...
