Perovskite-based tandem solar cells are of increasing interest as they approach commercialization. Here we use experimental parameters from optical spectroscopy measurements to calculate the limiting efficiency perovskite–silicon and all-perovskite two-terminal tandems, employing currently available bandgap materials, 42.0% 40.8%, respectively. We show luminescence coupling between subcells (th...

As more and more container terminals open up all over the world, competition for business is becoming very intense for container terminal operators. They are finding out that even to keep their existing Sea Line customers, they have to make them happy by offering higher quality service. The quality of service they can provide depends on their operating policies and the design of the terminal la...

In the perspective of biomedical applications, consider a re- current event situation with a relatively low degree of recurrence. In this setting, the focus is placed on successive inter-event gap times which are observed in the presence of both a terminal event like death and inde- pendent censoring. The terminal event is potentially related to recurrent events while the censoring process is a...

Sheep (ovine) pulmonary adenocarcinoma (SPA), also known as ovine pulmonary adneomatosis (OPA),jaagsiekte and ovine pulmonary carcinoma (OPC) is a contagious lung tumor in sheep and, more rarely, ingoats. This study was carried out in Khuzestan, in the southwest of Iran for a period of six months. A totalnumber of 3985 native breed goats were clinically inspected and postmortem examination was ...
