Sequential Notch signalling at the boundary of fringe expressing and non-expressing cells. [PDF]

PLoS ONE, 2012
Wing development in Drosophila requires the activation of Wingless (Wg) in a small stripe along the boundary of Fringe (Fng) expressing and non-expressing cells (FB), which coincides with the dorso-ventral (D/V) boundary of the wing imaginal disc.

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.

Experimental Investigation of Fracture Performances of SBHS500, SM570 and SM490 Steel Specimens with Notches

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,

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.

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.
