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.

Investigation of The Effect of Notch Tip Radius on Fracture Energy of Charpy in 7075 Aluminium Alloy [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2020 In the present study Charpy impact tests on a 7075-T651 aluminium alloy with full size (55×10×10 mm) with different notch tip radius (range of 0.19 to 0.40 mm) were conducted and the fracture energy was measured.

Metals, 2022 High-strength steels (HSSs) with nominal yield stress not less than 460 MPa have been increasingly employed in bridge structures. Compared with SM490 normal-strength steel (NSS), HSSs, including SBHS500 and SM570, have higher strength but lower ductility,

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.

The Evolution of the Maine Lobster V-Notch Practice: Cooperation in a Prisoner's Dilemma Game
Ecology and Society, 2011 The Maine lobster industry is experiencing record high catches because, in all probability, of an effective management program. One of the most important conservation measures is the V-notch program that allows fishermen to conserve proven breeding ...

Experimental investigation of fatigue crack initiation from notch for 2024 T351 Al-alloy
Fracture and Structural Integrity, 2020 In this investigation, fatigue criterion was established to predict crack-initiation at the tip of a notch in aged hardening aluminum alloy. This criterion was used to predict the residual lifetime in aeronautical structures using concept of local stress

Evaluation of the threshold values for the propagation of a fatigue crack starting at a V-notch
Computer Assisted Methods in Engineering and Science, 2023 This paper presents a simple method for evaluating the threshold value for fatigue cracks that emanate from a V-notch. The proposed method is based on the similarities between the elastic-stress fields around the tip of a crack and the tip of a V-notch.

JSES International, 2023 Background: The morphology of the suprascapular (SS) notch is a very important factor in treatment of suprascapular nerve (SSN) palsy. Several studies have reported SS notch morphology in cadavers or using a three-dimensional computed tomography (3D-CT);

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 ...
