In this paper, by using the idea of category, we investigate how the shape of the graph of h（x） affects the number of positive solutions to the following weighted nonlinear elliptic system： = （ N-2-2a 2. where 0 is a smooth bounded domain in ]1N （N 〉 3）, A, cr 〉 0 are parameters, 0 ≤ μ 〈 μa a 2 ＇ h（x）, KI（X） and K2（x） are positive continuous functions in , 1 〈 q 〈 2, a, β 〉 1 and a ＋ β = 2＊（a,b）（2＊（a, b） 2N = N-2（1＋a-b） is critical Sobolev-Hardy exponent）. We prove that the system has at least k nontrivial nonnegative solutions when the pair of the parameters （）, r） belongs to a certain subset of N2.

Background Although radial access for drug-eluting stent （DES） combined with rotational atherectomy （RA） in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary DES era. Methods ＆ Results This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial （TR） and transfemoral （TF） route in 126 consecutive patients （59 radial, 67 femoral） from 2009 to 2014. TR RA procedures were performed in 44/62 （71%） by the three TR operators, compared with 15/64 （23%） by the four TF operators in the present study. Significantly smaller diameter guide catheters and burrs （1.39 ± 0.16 mm vs. 1.53 ± 0.24 mm, P = 0.001） were used in the TR group. Procedural success rates were similar in both TR and TF groups. There was a significantly less major access site bleeding complications in favor of radial artery access （2% vs. 16%, P = 0.012）. The incidence of in-hospital death or myocardial infarction was low in both groups. Although a trend of lower adverse event rate was demonstrated in the TR group compared with the TF one, no statistical significance （21% vs. 27%, P = 0.135） was detected. Conclusions Radial access, a useful alternative to femoral access for RA and DES, can be safely and successfully performed on up to 71% of the patients with heavily calcified coronary lesions needing RA by experienced TR operators.

The mode serials of the Earth’s free oscillation provide some important information on the Earth’s deep structure and superconducting gravimeters （SG） can investigate the phenomena of the Earth’s free oscillations with high accuracy. The great Sumatra-Andaman earthquake fully excited the Earth’s free oscillations and these signals were perfectly recorded by five superconducting gravimeters in the globe. After the pre-treatment and spectral analysis on the SG observation data, we obtained the experimented mode serials of the Earth’s free oscillations consisting of 147 modes with GGP station data. These observed modes were themselves some new important data for the study of the Earth’s deep structure. On the basis of the discussions on some checked inner-core-sensitive modes, we distinguished three layers from the inner core, and the boundary of the upper layer was compatible with the formerly known transition zone in the inner core based on seismic body waves and supported that there were the hemispherical variation and very lower shear velocity zone in the lower inner core.

In the simulation of dynamics with curve-crossing, the states involved are close in energy, and the Born-Oppenheimer approximation breaks down. The dynamics is better described with diabatic states, which generally require additional conditions in their definition and description. Even though diabatic states are originally defined as the eigenstates of the kinetic energy operator, they are over-determined for systems with more than two atoms [1]. Thus, an alternative definition is necessary. Diabatic states are often defined as a state that retains certain key properties when the system moves along the reaction coordinate [2]. For example, the generalized Mulliken-Hush scheme, a useful method for for electron transfer, retains the dipole moment in the diabatic states [3]. The fragment excitation difference scheme is a similar method for energy transfer problems, in which the excitation population is localized to each fragment [4]. With a singlet exciton split into two triplet excitons, singlet fission has a great potential to increase the efficiency of solar cells. The Fragment Spin Difference（FSD） scheme was generalized to calculate the singlet fission coupling. Without manually including the CT components, the largest coupling strength obtained was 14.8 meV for two pentacenes in a crystal structure, or 33.7 meV for a transition-state structure, which yielded singlet fission lifetime of 239 or 37 fs, generally consistent to experimental result（80 fs）. We found that the charge on one fragment in the S1 diabatic state correlates well with FSD coupling, indicating the importance of the CT component. The FSD approach is a useful first-principle method for singlet fission coupling, without the need to include the CT component explicitly [5]. Further implementation for spin-completeness or a Restrictive Active Space（RAS） excitation improves the quality of excited states. The results predict well for a set of experimentally studied intramolecular singlet fission and tripl
