Dynamics of dark solitons in elongated Bose-Einstein condensates [PDF]
, 2001 We find two types of moving dark soliton textures in elongated Bose-Einstein condensates: non-stationary kinks and proper dark solitons. The former have a curved notch region and rapidly decay by emitting phonons and/or proper dark solitons.

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.

Arteriogenesis of the Spinal Cord—The Network Challenge
Cells, 2020 Spinal cord ischemia (SCI) is a clinical complication following aortic repair that significantly impairs the quality and expectancy of life. Despite some strategies, like cerebrospinal fluid drainage, the occurrence of neurological symptoms, such as ...

Gene regulatory network subcircuit controlling a dynamic spatial pattern of signaling in the sea urchin embryo [PDF]
, 2008 We dissect the transcriptional regulatory relationships coordinating the dynamic expression patterns of two signaling genes, wnt8 and delta, which are central to specification of the sea urchin embryo endomesoderm.

YAP/TAZ link cell mechanics to Notch signalling to control epidermal stem cell fate
Nature Communications, 2017 How the behaviour of somatic stem cells (SCs) is influenced by mechanical signals remains a black-box in cell biology. Here we show that YAP/TAZ regulation by cell shape and rigidity of the extracellular matrix (ECM) dictates a pivotal SC decision: to ...

Short crack initiation and growth at 600 °C in notched specimens of Inconel718
, 2003 The natural initiation and growth of short cracks in Inconel®718 U-notch specimens has been studied at 600 °C in air. U notches were introduced through broaching, and hardness traces and optical microscopy on cross-sections through the U notch broaching ...

Barriers to Investment Abroad as Tools of Payments Policy [PDF]
, 1969 The thesis examines the fatigue life of weld ends, where very little usable research previously has been conducted, and often the weld ends are the critical parts of the weld.

Using XFEM Techniques to Predict the Damage of aluminum 2024T3 notched under tensile load
Fracture and Structural Integrity, 2019 The objective of this work is to analyze some geometrical effect to predict the damage of aluminum 2024T3 structure after validate numerical model by experimental test. The mechanical of damage behaviour under tensile tests of several plates with notches
