Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

KIF1A‐Mediated Axonal Transport of Netrin‐1 in iPSC‐Derived Human Forebrain Neurons

Cytoskeleton, EarlyView.
ABSTRACT Netrin‐1 is a secreted laminin‐like protein that functions as a guidance cue for axon pathfinding in development. Netrin‐1 also modulates synapse formation in developing neurons and long‐term potentiation in mature neurons. Netrin‐1 is expressed in human neurons; however, its intracellular distribution and trafficking have not been assessed ...

A Control Strategy With Hybrid Compressor Modeling for Electric Vehicle CO2 Heat Pump Systems

Energy Science &Engineering, EarlyView.
A hybrid PSO‐BP compressor sub‐model is developed and embedded in a MATLAB/Simscape physical model of a transcritical CO2 heat pump system for electric vehicles. Based on this high‐fidelity platform, a phased variable‐PTC cooperative control strategy is proposed and evaluated.

Urinary and Faecal Amino‐Acids as Biomarkers for Colorectal Neoplasia in Lynch Syndrome—A Prospective Longitudinal Study

International Journal of Cancer, EarlyView.
ABSTRACT In Lynch syndrome, colonoscopy surveillance for colorectal cancer (CRC) is burdensome and post‐colonoscopy CRCs still occur. Unlike the faecal immunochemical test (FIT), gut metabolomic alterations including amino‐acids have shown potential as non‐invasive biomarkers for detecting both advanced and non‐advanced sporadic colorectal neoplasia ...

Characterization of cocoa butter diversity in Theobroma cacao L. in Trinidad.: implications for genetic improvement and chocolate quality

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Cocoa butter, the lipid fraction of Theobroma cacao L. seeds, is essential for chocolate quality and functionality, yet the full extent of natural variation in cocoa butter traits across cacao genetic diversity remains poorly characterized.
