A Fragile Points Method, with an interface debonding model, to simulate damage and fracture of U‐notched structures [PDF]
International Journal for Numerical Methods in Engineering, 2022 AbstractNotched components are commonly used in engineering structures, where stress concentration may easily lead to crack initiation and development. The main goal of this work is to develop a simple numerical method to predict the strength and crack‐growth‐path of U‐notched specimens made of brittle materials.

Notch promotes neural lineage entry by pluripotent embryonic stem cells [PDF]
, 2006 A central challenge in embryonic stem (ES) cell biology is to understand how to impose direction on primary lineage commitment. In basal culture conditions, the majority of ES cells convert asynchronously into neural cells.

An extension of the Equivalent Material Concept applied to fracture of U-notched solids
Procedia Structural Integrity, 2020 Abstract The Equivalent Material Concept is a tool that allows the fracture behavior of notched components in elastoplastic materials to be analyzed by transforming them into fictitious linear elastic ones, defining a fictitious failure stress. The combination of a failure criterion with this approach offers a methodology for predicting the maximum ...

Notch activates Wnt-4 signalling to control medio-lateral patterning of the pronephros [PDF]
, 2009 Previous studies have highlighted a role for the Notch signalling pathway during pronephrogenesis in the amphibian Xenopus laevis, and in nephron development in the mammalian metanephros, yet a mechanism for this function remains elusive.

Numb is not a critical regulator of Notch-mediated cell fate decisions in the developing chick inner ear. [PDF]
, 2015 The Notch signaling pathway controls differentiation of hair cells and supporting cells in the vertebrate inner ear. Here, we have investigated whether Numb, a known regulator of Notch activity in Drosophila, is involved in this process in the embryonic ...
