Algorithms for the quantitative Lock/Key model of cytoplasmic incompatibility

open access: yesAlgorithms for Molecular Biology, 2020
Cytoplasmic incompatibility (CI) relates to the manipulation by the parasite Wolbachia of its host reproduction. Despite its widespread occurrence, the molecular basis of CI remains unclear and theoretical models have been proposed to understand the ...

Two-piece obturator using “lock-and-key” mechanism

open access: yesThe Journal of Indian Prosthodontic Society, 2017
This paper describes a method used for the fabrication of a two-piece denture obturator for a patient who had surgical removal of the premaxilla due to squamous cell carcinoma. The patient had been wearing a two-piece obturator but encountered difficulty

A new model and method for understanding Wolbachia-induced cytoplasmic incompatibility. [PDF]

open access: yesPLoS ONE, 2011
Wolbachia are intracellular bacteria transmitted almost exclusively vertically through eggs. In response to this mode of transmission, Wolbachia strategically manipulate their insect hosts' reproduction.

CAS-Lock: A Security-Corruptibility Trade-off Resilient Logic Locking Scheme

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2019
Logic locking has recently been proposed as a solution for protecting gatelevel semiconductor intellectual property (IP). However, numerous attacks have been mounted on this technique, which either compromise the locking key or restore the original ...

Investigating Information Dynamics in Living Systems through the Structure and Function of Enzymes. [PDF]

open access: yesPLoS ONE, 2016
Enzymes are proteins that accelerate intracellular chemical reactions often by factors of 105-1012s-1. We propose the structure and function of enzymes represent the thermodynamic expression of heritable information encoded in DNA with post-translational

Wear analysis of finger locks with different design parameters for landing gear

open access: yesScience Progress, 2020
The finger lock in the retractable actuator of the landing gear will wear during repeated unlocking and locking. Therefore, the effects of six parameters including the material of the finger lock, the length of the finger lock, the diameter of the finger
