The cell fate decision of multi-potent pancreatic progenitor cells between the exocrine and endocrine lineages is regulated by Notch signalling, mediated by cell-cell interactions. However, canonical models of Notch-mediated lateral inhibition cannot explain the scattered spatial distribution of endocrine cells and the cell-type ratio in the developing pancreas. Based on evidence from acinar-to...

in this paper, chaotic motion analysis and its control for a non-planar non-linear cantilever beam with axial and lateral parametric excitation in the free end is accomplished. this is a new method for control of chaotic motion of a non-linear planar beam. in this survey, internal resonance of the beam is 2:1 and the initial resonance is in the outside of plane and it is assumed a sub-resonance...

in many structures, the applied lateral loads are comparable with gravity loads. these types of piles which are subject to high lateral load are usually divided into two categories including long and short piles. the general methods to estimate lateral bearing capacity of short and long piles are based on ultimate bearing capacity and allowable horizontal displacement respectively. in the prese...

The purpose of this work is to examine the possibility using multi-angle conventional ultrasound B-mode scanning in efficient 3-D imaging. In paper, volume an object reconstructed from vertical projections registered at fixed angular positions multi-element linear ultrasonic probe rotated relation submerged water. possible configurations are: lateral, top or bottom. lateral configuration, acqui...

Optimizing the LA-ICP-MS procedure to obtain 2D and 3D high-resolution multi-elemental imaging of heavily degraded Roman glass for studying weathering mechanisms by monitoring lateral in-depth distribution elements.
