Availability of a Periodically Inspected System Maintained through Several Minimal Repairs before a Replacement or a Perfect Repair [PDF]

Abstract and Applied Analysis, 2013
The instantaneous availability of a periodically inspected system with several minimal repairs before a replacement or a perfect repair is studied. First, we investigate two concrete minimal repair models with periodic inspection and constant repair time

System Maintenance Using Several Imperfect Repairs Before a Perfect Repair

Statistics, Optimization & Information Computing, 2021
Allowing several imperfect repairs before a perfect repair can lead to a highly reliable and efficient system by reducing repair time and repair cost. Assuming exponential lifetime and exponential repair time, we determine the optimal probability $p$ of choosing a perfect repair over an imperfect repair after each failure.

Cas9 exo-endonuclease eliminates chromosomal translocations during genome editing

Nature Communications, 2022
Chromosomal structural variations induced by CRISPR/Cas hinder its application in clinics. Here, the authors fuse Cas9 with optimized TREX2 to generate Cas9TX, which can prevent perfect repair and inhibit repeated cleavage.

Interactions Between Immunomodulatory Biomaterials and Immune Microenvironment: Cues for Immunomodulation Strategies in Tissue Repair

Frontiers in Bioengineering and Biotechnology, 2022
The foreign body response (FBR) caused by biomaterials can essentially be understood as the interaction between the immune microenvironment and biomaterials, which has severely impeded the application of biomaterials in tissue repair.
