Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS 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.

Analytical design of optical color filter using bi-layered chiral liquid crystal
, 2022 We introduce an optically controllable color filter model using bi-layered CLC structure. From mathematical parameter sweep analysis using 4×4 matrix method, wavelength controls of red, green, and blue optical color filters and tailored tuning of optical

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Two-Way Optical Time and Frequency Transfer Over a 20-km Fiber Link Based on Optical Frequency Combs
IEEE Photonics Journal, 2019 Traditional high-precision long-distance time–frequency transmission requires a complex compensation structure and a continuous optical link, which make high-precision transmission difficult.

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
, 2007 The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence
