The example of the ‘‘absent-minded driver’’ was introduced by Piccione and Rubinstein in the context of games and decision problems with imperfect recall. They claim that a ‘‘paradox’’ or ‘‘inconsistency’’ arises when the decision reached at the ‘‘planning stage’’ is compared with that at the ‘‘action stage.’’ Though the example is provocative and worth having, their analysis is questionable. A...

Two experiments were conducted to explore Gillam and Borsting's (1988, Perception 17 603-608) report that uncorrelated monocular texture facilitates stereopsis by shortening the latency to see depth in random-dot stereograms. Experiment 1 used stereograms similar, in pattern but not disparity, to Gillam and Borsting's with monocular texture present or absent. A third condition, where monocular ...

Absent or abnormal laxity of splenic ligaments may give rise to a rare condition called wandering spleen. This can be difficult diagnose due its non-specific symptoms and clinical findings which are often missed the patient presents late with life-threatening complication.

Patient presentation: An otherwise healthy 29-year-old white woman presented to our emergency department with leg pain and edema. She was well until 2 weeks before, when she developed lower back pain following a 3-hour flight. Her pain progressed despite treatment with ice packs, nonsteroidal anti-inflammatory drugs, and stretching, and it became so severe that she was unable to sit comfortably...

Biological proteins are known to fold into specific 3D conformations. However, the fundamental question has remained: Do they fold because they are biological, and evolution has selected sequences which fold? Or is folding a common trait, widespread throughout sequence space? To address this question arbitrary, unevolved, random-sequence proteins were examined for structural features found in f...

Empty sella turcica is a condition in which the pituitary gland absent completely or partially from fossa. The patient may be asymptomatic with empty as an incidental finding, have symptoms of hormones deficiency. Perioperative management these patients depends on and signs hormonal deficiencies replacement treatment.

Complete absence of the nose (arhinia) is an extremely rare congenital condition with very few cases having been reported in the literature1-23. Many children born with this condition do not survive past infancy as the associated malformations are often not compatible with life 24. Rosen 25 classified partial arhinia as that condition where the rhinencephalon is present, while in total arhinia,...
