Novae and supernovae are among the most violent explosive events known in nature. They can arise in two ways: from single star evolution, as Type II supernovae; or from binary star evolution, as novae and Type Ia Supernovae. The possible evolutionary link between the two latter classes will be addressed, together with some major results from multiwavelength observations of SN 1987A and of recen...

Wireless networks are often modelled using geometric graphs. Using only local geometric information to compute a sequence of distributed forwarding decisions that send a message to its destination, routing algorithms can succeed on several common classes of geometric graphs. These graphs’ geometric properties provide navigational cues that allow routing to succeed using only limited local infor...

Background: Breast reconstruction by using the rectus abdominis muscle (transverse rectus abdominis myocutaneous, TRAM) flaps is a common procedure that has been per­ formed since the 1990s. Ipsilateral TRAM flaps were proven to be as safe as contralateral flaps for breast reconstruction. However, studies comparing the aesthetic outcomes of the two procedures are poorly described in the literat...

Introduction: Although many factors can affect the choice of destination in medical tourism, some factors are indispensable to medical tourists and medical tourism. The aim of this study was to analyze important factors affecting the selection of a destination by potential medical tourists. Methods: This descriptive, cross-sectional study, conducted in Tu...
