The stable bound state, the quasi-bound state and the diffusion state are predicted. The thresholds for transition between the different states are obtained and the stability diagram in parameter space is presented. The tunnelling dynamics of the system in different states is revealed. The shape of the potential well and the atomic interaction play important role and have coupled effect on the tunnelling dynamics of the system. Furthermore, the resonant tunnelling phenomenon in the parametrically modulated shallow trap is observed. The results show that when the modulating frequency approaches the dipolar mode of the system, resonant tunnelling occurs and the whole system is unstable. Our results provide a theoretical evidence for studying the tunnelling dynamics of the ultracold atomic system.

Family dinner frequency, family relationship, life satisfaction (LS), self-perceived health and anxiety were assessed by validated questionnaires. Of 14,274 participants, 50.6% were boys and 71.4% were urban residents, with a mean (SD) age of 12.28 (3.16) years. Family dinner frequency was significantly correlated with LS (boys: β = 0.27, p
In this study we explored the use of a natural compound rubusoside (RUB) as a solubilizer to enhance the solubility of a fluorescence-labeled C6-Ceramide (NBD C6-Ceramide) and to characterize its pharmacokinetics and tissue distribution in an animal model. RUB significantly enhanced the solubility of NBD C6-Ceramide by forming nanomicelles, and efficiently delivered NBD C6-Ceramide in rats by oral and intravenous administration. RUB loaded 1.96% of NBD C6-Ceramide in the nanomicelles and solubilized it to a concentration of 3.6 mg/mL in water. NBD C6-Ceramide in nanomicelles remained stable in aqueous solutions, all...

ConteAbstractInflammation ensuing from vascular injury promotes intimal hyperplasia (IH) and restenosis. Resolvin D1 (RvD1) is a lipid mediator that attenuates IH in vivo when delivered locally to the vessel wall in animal models. We tested the hypothesis that peri-procedural oral administration of RvD1 could blunt the local inflammatory response to angioplasty, and attenuate downstream IH. Carotid angioplasty was per...
