In this thesis we study the problem of computing a straight-line representation of a planarization with a fixed combinatorial structure. By the results of Mnëv [Mnë88] and Shor [Sho91] this problem is as hard as the Existential Theory of the Reals (∃R-Complete). We present a heuristic called Geometric Planarization Drawing to compute a straight-line representation of a planarization. We take an...

The draw for the 2022 FIFA World Cup has been organised before identity of three winners play-offs is revealed. Seeding based on Ranking released 31 March but these teams have drawn from weakest Pot 4. We show that official seeding policy does not balance difficulty levels groups to extent possible: a better alternative would assign placeholders according highest-ranked potential winner, simila...

Clear cell sarcoma of the kidney (CCSK) is an uncommon renal neoplasm of childhood. It represents between 2% and 9% of all pediatric renal tumors, and generally arises before the age of 5 years. It often mimics other pediatric renal tumors. Presently described is the case of a 7-year-old girl who presented with complaints of vomiting and abdominal pain. Abdominal ultrasonography revealed a righ...

Relational databases have been used to represent lexical knowledge since the days of machine-readable dictionaries. However, although software engineering provides a methodological framework for the construction of databases, most developing efforts focus on content, implementation and timesaving issues, and forget about the software engineering aspects of database construction. We have defined...

From its start, the so-called Islamic State of Iraq and the Levant (ISIL/ISIS) has been successfully exploiting social media networks, most notoriously Twitter, to promote its propaganda and recruit new members, resulting in thousands of social media users adopting pro-ISIS stance every year. Automatic identification of pro-ISIS users on social media has, thus, become the centre of interest for...

BACKGROUND Fallopian tube torsion is a cause for acute low abdominal pain that is difficult to diagnose. The purpose of this article is to review the available data on and to update clinicians regarding its diagnosis and treatment in the era of laparoscopic surgery. METHODS We searched in MEDLINE and EMBASE and reviewed the lists of references. The keywords used were "laparoscopy," "fallopian...

Liver.?This showed marked areas of congestion. When I passed my hand into the abdominal cavity to get behind the liver 1113' fingers were arrested by what turned out to be bands of adhesion which bound about an inch of the upper surface of the liver to the abdominal wall^ of the diaphragm. These bands were about three-quarters of an inch in length. On cutting these bands I was able to draw up t...
