From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Tests and Simulation Research on the Output Energy of Microdetonators [PDF]

open access: yesIEEE Access, 2019
To make up for the deficiencies in the present method of measuring microdetonator output energy, this paper uses PVDF (Polyvinylidene Fluoride) piezoelectric films as sensors and designs a system to test the output pressure of microdetonators with a 2.5 mm diameter. The average measured output pressure was 9.87GPa.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Predicting Output Power for Nearshore Wave Energy Harvesting

open access: yesApplied Sciences, 2018
Energy harvested from a Wave Energy Converter (WEC) varies greatly with the location of its installation. Determining an optimal location that can result in maximum output power is therefore critical.
