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...

This paper presents a framework to study countries’ export potentials. It uses gravity model develop measures of and trade policy potentials at the aggregate, bilateral, industry levels. The methodology is applied case Turkey. analysis finds that Turkey was moderately under-exporting over 2010-17. United States, China, Japan are important untapped destination markets, accounting for US$29 bil...
