Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

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 ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Sub-Synchronous Oscillation Suppression Based on VSG Virtual Impedance Feasible Domains

open access: yes南方能源建设
[Objective] The virtual synchronous generator (VSG) system exhibits negative damping characteristics under weak grid connection, which triggers subsynchronous oscillations and leads to system instability.

Collision-Free Path Planning for Cooperative Aerial Manipulators Under Velocity and Curvature Constraints

open access: yesIEEE Access, 2019
This paper presents a path planning problem with velocity and curvature constraints for cooperative aerial manipulators in obstacle environments. While potential-flow-based path planning approaches can help generate smooth paths in which cooperative ...
