Statistical optimization of the growth factors for Chaetoceros neogracile using fractional factorial design and central composite design.

Journal of microbiology and biotechnology, 2009
Statistical experimental designs; involving (i) a fractional factorial design (FFD) and (ii) a central composite design (CCD) were applied to optimize the culture medium constituents for production of a unique antifreeze protein by the Antartic microalgae Chaetoceros neogracile.

Textural characterization of agar–agar and guar gum‐based hydrocolloids in vegan gummies: Effects of acid and sugar

Food Biomacromolecules, EarlyView.
Abstract This study explores the potential of replacing gelatin with vegan hydrocolloids as gelling agents in gummies. The goal was to create a gelatin‐free, vegan gummy using natural plant‐based hydrocolloids such as agar–agar and guar gum, which provide a chewy texture similar to gelatin.

A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

Journal of Forecasting, EarlyView.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.

Impacts of tillage on soil properties and interactions with drainage when reseeding permanent pasture

Grassland Research, EarlyView.
Effect of three‐way interaction between soil tillage, drainage and depths on soil properties in reseeded pastures. Abstract Background Grassland reseeding typically requires intensive tillage. This disrupts soil nutrient dynamics, especially under varying drainage conditions. Methods This study evaluated the combined effects of tillage legacy, drainage

Development and psychometric properties of a general cancer stigma scale

International Journal of Cancer, EarlyView.
What's New? Cancer‐related stigma can fuel anxiety and depression and lead to self‐isolation, delayed treatment, and decreased quality of life. The extent to which stigma impacts cancer patients, however, remains uncertain. This study applied mixed methods in high‐ and low‐income settings, with cohorts in the U.S. state of Utah and Lilongwe, Malawi, to
