Debonding criterion for the piezoelectric fibre push-out test [PDF]

open access: yesPhilosophical Magazine Letters, 2006
A theoretical model of piezoelectric fibre push-out is developed within the framework of a modified shear-lag theory to study stress and electrical field transfer. Based on the model, a debonding criterion for the piezoelectric effect is presented utilizing a fracture-mechanics approach to investigate the debonding process of piezoelectric fibre in the

Observation-Based Modeling for Testing and Verifying Highly Dependable Systems – A Practitioner’s Approach [PDF]

open access: yes, 2009
Model-based testing (MBT) can reduce the cost of making test cases for critical applications significantly. Depending on the formality of the models, they can also be used for verification.

Modeling of the Steel-Concrete Push-Out Test

open access: yesProcedia Engineering, 2012
In steel-concrete composite structures, the behavior of the shear connections is of great importance. This behavior is generally characterized by the load-slip curve obtained from experimental push-out tests, however these tests are expensive and time-consuming. In this study, a numerical model is developed to represent the behavior of a push-out test.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
