Primates live in highly social environments, where prosocial behaviors promote social bonds and cohesion and contribute to group members' fitness. Despite a growing interest in the biological basis of nonhuman primates' social interactions, their underlying motivations remain a matter of debate. We report that macaque monkeys take into account the welfare of their peers when making behavioral c...

We present a new algorithm for reducing an arbitrary unitary matrix U into a sequence of elementary operations (operations such as controlled-nots and qubit rotations). Such a sequence of operations can be used to manipulate an array of quantum bits (i.e., a quantum computer). Our algorithm applies recursively a mathematical technique called the CS Decomposition to build a binary tree of matric...

In recent years the more frequent use of x-rays has revealed various congenital abnormalities of the lungs which had formerly passed undetected during life, since the clinical signs and symptoms may be minimal. An attempt is made here to elucidate the different pictures which may be seen in varying degrees of underdevelopment of the lungs. For clarity of description the following nomenclature i...

Rupture of the bronchus has become more common in the last decade, mainly due to an increase in road traffic accidents. In spite of this increase it is still relatively rare, and most thoracic surgeons do not have the personal experience of treating more than two or three cases in their life-time. In 1947 Kinsella and Johnsrud reviewed the world literature on intrathoracic rupture of the trache...

The diagnosis of bronchus cardiacus accessorius dexter (BCAD) has occurred in 25 cases during the bronchoscopic investigations of 30,000 adult patients of the authors. In most of the cases, this bronchial anomaly has been revealed as an accessory phenomenon, nevertheless, in one of the patients, it was the source of a considerable hemorrhage. In another case reported here in detail, it occurred...

Term, live abdominal pregnancy secondary to rupture of a uterine rudimentary horn is a rare condition. Pregnancies conceived in the rudimentary horn of the uterus usually rupture during early gestation and present as a catastrophic event. However, rarely, after rupture of the uterine horn the foetus may continue to grow in the abdominal cavity and reach term gestation. A primigravida with a ter...

Pregnancy in non-communicating rudimentary horn of unicornuate uterus is an uncommon form of ectopic pregnancy usually resulting in rupture during second trimester with grave consequences for the mother and fetus. We report a case of ruptured non-communicating rudimentary horn at 28 weeks of gestation in woman with previous Caesarean section in unicornuate uterus. She presented to emergency wit...

Pregnancy in a non-communicating rudimentary horn is very difficult to diagnose before it ruptures, leading to life -threatening intraperitoneal hemorrhage. A 22-year-old second gravida patient presented at the Emergency Center of the University Clinical Center of Kosova with a 16-week history of amenorrhea and acute onset of severe abdominal pain. She was resuscitated and taken for an emergenc...

Pregnancy in non-communicating rudimentary horn is rare. It occurs following transperitoneal migration of sperms or zygote. Uterine rupture usually occurs in 70-90% cases in the second trimester by 20 weeks. Diagnosis of rudimentary horn pregnancy and its rupture in a woman is difficult. It can be missed in routine ultrasound scan and in majority of cases it is detected after rupture. It requir...

Pregnancy in the rudimentary horn is rare and represents a form of ectopic gestation. Despite advances in ultrasound, prenatal diagnosis remains elusive, with confirmatory diagnosis being made at laparotomy. Because of variable muscular constitution of the wall of the rudimentary horn, pregnancy can be accommodated until late in pregnancy, when rupture occurs manifesting commonly as acute abdom...
