Article Synopsis
- The research discusses an unsupervised classification method using a latent variable to categorize a scalar response into multiple components in a mixture model that includes both scalar and functional covariates.
- It suggests a hierarchical modeling approach, where the first level uses parametric distributions for the scalar response and the second level utilizes a generalized linear model to handle the mixture probabilities.
- Additionally, the method addresses issues with conventional approaches that treat functional covariates as vectors, proposing a Bayesian approach that reduces dimensionality through basis expansions, with practical applications in clinical trials and agricultural settings.
Novel materials using biowaste as adsorbents in wastewater treatment have been allocated considerable interest. Herein, we present the synthesis of different hydrogels of crosslinked polyacrylamide in presence of hemicelluloses with/ without bentonite, using a soft reaction condition. The structure of new hydrogels was characterized by spectroscopic, thermal and microscopic experiments.

Patients and families are also concerned about practical considerations regarding shoe wear and the appearance of the calf. The purpose of this study was to quantify whether children treated for idiopathic clubfoot have symmetry differences in shoe size and calf girth when presenting with unilateral versus bilateral involvement.

The modification in the CNFs was carried out with three simple routes using a low molecular weight polylactic acid synthesized in our laboratory (PLA1). The first step comprises of protection of the hydroxyl groups of PLA1 through a benzoylation (PLA1Bz).

- Gamma radiation offers a cost-effective and efficient method for producing starch nanoparticles (SNP), which are scalable and easy to make.
- Starch nanoparticles with sizes around 20-30 nm were successfully created from cassava and waxy maize starch using a gamma radiation dose of 20 kGy, demonstrating similar thermal properties to those obtained via acid hydrolysis.
- When used as nanofillers in a cassava matrix, the inclusion of just 2.5 wt.% of these SNP significantly increased the material's storage modulus by 102%, indicating their potential for enhancing starch-based materials.
Purpose: To investigate the effect of treated clubfoot disorder on gross motor skill level measured by the Alberta Infant Motor Scale (AIMS).
Methods: Fifty-two babies participated: 26 were treated for idiopathic clubfoot (12 with the Ponseti treatment method, 9 with the French physical therapy technique, and 5 with a combination of both methods); 26 were babies who were typically developing and without medical diagnoses. The AIMS was administered at 3-month intervals.
