Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Notching on Cancer’s Door: Notch Signaling in Brain Tumors [PDF]
Frontiers in Oncology, 2015 Notch receptors play an essential role in the regulation of central cellular processes during embryonic and postnatal development. The mammalian genome encodes for four Notch paralogs (Notch 1-4), which are activated by three Delta-like (Dll1/3/4) and two Serrate-like (Jagged1/2) ligands.

Car Notches: Strategic Automaker Responses to Fuel Economy Policy [PDF]
Notches --- where small changes in behavior lead to large changes in a tax or subsidy --- figure prominently in many policies, but have been rarely examined by economists.

core
Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Effect of micro-notches on fatigue strength of electrodeposited nanocrystalline nickel thin films
MATEC Web of Conferences, 2018 The effect of micro-notches on the fatigue strength of nickel thin films was studied. Two types of thin films with 10 μm thickness were produced by electrodeposition using sulfamate solution without and with brightener: ultra-fine grained film (UFG) with

Minima in cubic distortion-product otoacoustic emission input/output functions due to distributed primary sources [PDF]
JASA Express LettersInput/output (I/O) functions of distortion-product otoacoustic emissions (DPOAEs) may contain sudden amplitude minima (notches) although they are measured in animals with a negligible reflection source.

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales
Advanced Engineering Materials, EarlyView.Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

"Notch-Off": a perspective on the termination of Notch signalling
The International Journal of Developmental Biology, 2009 During Notch mediated lateral inhibition, interacting cells establish or amplify differences in Notch signalling, which are then translated into distinct cell fate decisions according to the developmental context. In recent years, several mechanisms that increase the signalling capacity of interacting cells have been uncovered (reviewed in Bray, 2006 ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
