Effect of the addition of yacon flour (Smallanthus sonchifolius) and freezing on baking performance

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Yacon (Smallanthus sonchifolius), a tuber rich in fructans, presents potential for application in breadmaking due to its nutritional properties and cryoprotectant activity. The aim of this study was to evaluate the incorporation of yacon flour in bread formulations (50 g/kg and 100 g/kg on flour mixture basis) and its impact on ...

Long‐term follow‐up and combined Phase 2 results of eprenetapopt and azacitidine in patients with TP53 mutant MDS/AML

HemaSphere
TP53 gene mutations (mTP53) represent a distinct molecular cohort with poor outcomes. Eprenetapopt (APR‐246) is a novel, first‐in‐class small molecule that reactivates p53 and targets cellular redox balance, ultimately inducing apoptosis and ferroptosis ...

Stability Analysis and Improvement Mechanism of Grid‐Forming Converter Connected to a Low‐Impedance Grid

High Voltage, EarlyView.
ABSTRACT This paper investigates the stability and improvement mechanisms of a grid‐forming (GFM) converter connected to a low‐impedance grid. Initially, a state‐space model of the GFM converter integrated into an AC grid is developed for stability analysis.
