The D dimensional quasi exact solutions for the singular even power anharmonic potential V (q) = aq2 + bq−4 + cq−6 are reported. We show that whilst Dong and Ma’s [5] quasi exact ground state solution (in D=2) is beyond doubt, their solution for the first excited state is exotic. Quasi exact solutions for the ground and first excited states are also given for the above potential confined to an ...

Perovskite Solar Cells In article 2208061, Lukas E. Lehner, Martin Kaltenbrunner, and co-workers report the controlled nucleation of quasi-2D perovskites at liquid–air interface precursor solution. Restricting initial crystal growth to surface liquid results in highly aligned perovskite thin films with improved charge transport, enabling efficient solar cells excellent stability.

In this paper, we consider the system of vector quasi-equilibrium problems with or without involving -condensing maps and prove the existence of its solution. Consequently, we get existence results for a solution to the system of vector quasi-variational-like inequalities. We also prove the equivalence between the system of vector quasi-variational-like inequalities and the Debreu type equilibr...

We have developed, implemented and validated a set of flexible and efficient iterative image reconstruction (IIR) and processing methods for clinical positron emission tomography (PET) static or dynamic studies. IIR techniques are shown to produce images of better contrast and signal-to-noise ratio than the conventional filtered back-projection (FBP). Their high computational cost has been a si...

The most recent trend in the Information and Communication Technology world is toward an ever growing demand of mobile heterogeneous services that imply the management of different quality of service requirements and priorities among different type of users. The long-term evolution (LTE)/LTE-advanced standards have been introduced aiming to cope with this challenge. In particular, the resource ...
