In the nervous system, axonal pathways are shaped by repulsive cues provided by ligands of the semaphorin family that are sensed by migrating neuronal growth cones through plexin receptors.
Such interactions are ubiquitous in highly volume-occupied physiological fluid media, and result in significant size- and shape-dependent repulsive contributions to the chemical potential of each macromolecular species that tend to stabilize more compact conformations relative to less-compact conformations [12], [13].
In order to achieve this defined architecture, the embryo integrates a multitude of attractive and repulsive cues to guide and shape the developing vasculature.
To get analytical expressions for elementary scattering amplitudes in the N-I-n-S structure, we model barrier I by a short-range repulsive potential of a rectangular shape U x) = U 0 and the thickness d I.
The CNTs did not aggregate and form the cylindrical shape because of the similar repulsive interaction parameter between the CNT and PE polymers.
Rotting flesh is merely repulsive, not aesthetically repulsive.
The spherical shape of the particles allows us to suggest on repulsive forces between P3HT and PMMA, where amorphous ("liquid-like") phase of P3HT tends to separate from PMMA matrix into compact particles possessing a minimal surface.
A low-resolution shape complementarity search translates and rotates the ligand optimizing attractive and repulsive score terms.
The competition between these potentials can generate a repulsive or attractive bending in the total potential since their sum will determine the shape of this bending inside the well.
The time-out mechanism or repulsive velocity-loss mechanism is necessary for these eyespots to be fixed in a typical shape.
Realizing the importance we explore the excitation kinetics of a repulsive impurity doped quantum dot induced by an electromagnetic pulsed field of various pulse shapes.
