Identification of a Ternary Nitride TiCuN with a Unique Structure Type.

This study presents the synthesis and detailed structural analysis of the ternary nitride TiCuN. Initially identified as TiCuN within the Ti-Cu-N ternary phase diagram, its crystal structure remained unresolved and was characterized solely as belonging to the tetragonal crystal system.

Multilevel Latent Differential Structural Equation Model with Short Time Series and Time-Varying Covariates: A Comparison of Frequentist and Bayesian Estimators.

Continuous-time modeling using differential equations is a promising technique to model change processes with longitudinal data. Among ways to fit this model, the Latent Differential Structural Equation Modeling (LDSEM) approach defines latent derivative variables within a structural equation modeling (SEM) framework, thereby allowing researchers to leverage advantages of the SEM framework for model building, estimation, inference, and comparison purposes. Still, a few issues remain unresolved, including performance of multilevel variations of the LDSEM under short time lengths (e.

From intention to behavior: Within- and between-person moderators of the relationship between intention and physical activity.

Intention is a proximal predictor of behavior in many theories of behavior change, but intentions to be physically active do not always translate to actual physical activity. Little research has examined intensive longitudinal changes in physical activity and corresponding within-person moderators needed to elucidate the mechanisms, hurdles, and facilitators of individuals' everyday physical activity behaviors. The present study set out to evaluate the possible moderators of the intention-physical activity relationship across within-person and between-person levels, including cross-level interactions.

In Study I, hypothyroidism, thyroiditis, autoimmune thyroiditis, hyperthyroidism, and Graves' disease showed positive associations with thyroid cancer.

Design of V-Substituted TiFe-Based Alloy for Target Pressure Range and Easy Activation.

Titanium iron (TiFe) alloy is a room-temperature hydrogen-storage material, and it absorbs hydrogen via a two-step process to form TiFeH and then TiFeH. The effect of V addition in TiFe alloy was recently elucidated. The V substitution for Ti sublattice lowers / ratio, where and are the equilibrium plateau pressure for TiFe/TiFeH and TiFeH/TiFeH, respectively, and thus restricts the two-step hydrogenation within a narrow pressure range.

Nanofiber Channel Organic Electrochemical Transistors for Low-Power Neuromorphic Computing and Wide-Bandwidth Sensing Platforms.
