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.

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

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 ...
