COMPUTER STUDIES OF THE DYNAMIC STRENGTH OF CERAMICS [PDF]

open access: yesLe Journal de Physique IV, 1991
Using a new constitutive model, computer studies were performed concerning the dynamic yield strength of six ceramics, SiC, TiB2, AlN, two types of B4C, and partially stabilized zirconia. The relative importance of the thermomechanical variables, strain, strain-rate, pressure, and temperature, as well as the Bauschinger effect, is demonstrated in ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Change in Acoustic Parameters of Electric Guitar Strings Under Dynamic Loading

open access: yesSensors
The aim of our work was to investigate how electric guitar strings wear out. There are many myths about string wear. We decided to investigate what the wear process looks like in real life.

Dynamic strength of molecular adhesion bonds

open access: yesBiophysical Journal, 1997
In biology, molecular linkages at, within, and beneath cell interfaces arise mainly from weak noncovalent interactions. These bonds will fail under any level of pulling force if held for sufficient time. Thus, when tested with ultrasensitive force probes, we expect cohesive material strength and strength of adhesion at interfaces to be time- and ...
