However, the interaction between PS brushes and PEG substrate is repulsive [19, 20].
We illustrate with three one-dimensional examples —a time-dependent harmonic oscillator, a double-well anharmonic oscillator, and the repulsive 1x2 potential and find good agreement between the numerically calculated and exact paths where analytical results are available for comparison.
In addition, electrostatic and van der Waals energy of mannose are repulsive (5.6 and 2.6 kcal/mol, respectively), whereas for taurolidine they are the most negative (−103.4 and −5.6 kcal/mol respectively) in Table 1; it is clear that the affinity of mannose for the active site of FimH is mainly due to its several H-bonds, Figure 11.
We showed that these substrate-bound repulsive ephrinA5 gradients elicit a stop reaction for temporal RGC axons.
(C ) Chemotaxis performance of wild-type young (day 1) and aged (day 5) adults towards a point source of repulsive 2-nonanone odor.
Responses in the repulsive DM5 glomerulus are decreased, at the same time as responses in the attractive DM1 glomerulus are increased.
In a specular fashion, activation of the repulsive EphA2 receptor in prostate carcinoma cells is accompanied by reduced Rac1 activity and attenuated generation of ROS, which leads to LMW-PTP activation, p190RhoGAP dephosphorylation and to an increase of Rho signaling [ 83, 96].
With 4,4-difluoropentan-2-ol E, the higher stabilization of the g− g + g− (g + ) vs. g− g + t (g + ) conformers is explained by the attractive CH⋅⋅⋅F contribution in the former replaced by a repulsive CH⋅⋅⋅CH3 interaction in the latter.
Recall that for the deterministic (1.2) with a repulsive potential ((theta>0)), Carles [4] proved that the potential could prevent the blow-up of the solution.
While F4TCNQ molecules are known to form cohesive 3D solids, the intermolecular interactions that are attractive for F4TCNQ in 3D are repulsive in 2D.
Our calculation also supported the limited charge transfer due to strong intermolecular repulsive interaction [35, 36].
