Biomimetic Growth of Calcium Oxalate Hydrates: Shape Development and Structures in Agar Gel Matrices
Chemistry – A European Journal, EarlyView.The biomimetic growth of calcium oxalate hydrates is conducted using a double diffusion technique in agar gel. The results reveal the shape development of calcium oxalate monohydrate (COM) and dihydrate (COD), resembling biominerals of kidney stones. The pH variations influence phase selection, with COM forming at lower pH and COD at higher pH.

Chemistry – A European Journal, Accepted Article.Short amyloidogenic oligopeptides (APRs) are proposed as early macromolecules capable of forming solvent‐separated nanosystems under prebiotic conditions. This study provides experimental evidence that APRs, such as the aggregation‐prone oligopeptide A (APR‐A), can undergo mutational transitions to form distinct variants, and convert to APR‐B, either ...

Fast and scalable inference for spatial extreme value models
Canadian Journal of Statistics, EarlyView.Abstract The generalized extreme value (GEV) distribution is a popular model for analyzing and forecasting extreme weather data. To increase prediction accuracy, spatial information is often pooled via a latent Gaussian process (GP) on the GEV parameters. Inference for GEV‐GP models is typically carried out using Markov Chain Monte Carlo (MCMC) methods,

A parameter transformation of the anisotropic Matérn covariance function
Canadian Journal of Statistics, EarlyView.Abstract We describe a polar coordinate transformation of the anisotropy parameters of the Matérn covariance function, which provides two benefits over the standard parameterization. First, it identifies a single point (the origin) with the special case of isotropy.

An introduction to causal inference for pharmacometricians
CPT: Pharmacometrics &Systems Pharmacology, Volume 12, Issue 1, Page 27-40, January 2023., 2023 Abstract As formal causal inference begins to play a greater role in disciplines that intersect with pharmacometrics, such as biostatistics, epidemiology, and artificial intelligence/machine learning, pharmacometricians may increasingly benefit from a basic fluency in foundational causal inference concepts.

Dynamics Data Encryption Based on Chaotic Functions and Elliptic Curves: Application to Text Data
Al-Mustansiriyah Journal of ScienceBackground: Given the vast amount of data generated daily on the Internet, numerous cryptosystems have been developed to ensure data confidentiality using symmetric, asymmetric, or hybrid encryption techniques. However, many of these systems suffer from

The PP2A‐B56 Binding Site LxxIxE Contributes to Asp‐Mediated Spindle Pole Stability
Cytoskeleton, EarlyView.ABSTRACT The organization of microtubules into a mitotic spindle is critical for animal cell proliferation and involves the cooperation of hundreds of proteins whose molecular roles and regulation are not fully understood. The protein product of the Drosophila gene abnormal spindle, Asp, is a microtubule‐associated protein required for correct mitotic ...
