His argument is based on the assumption that women’s utility is higher if they are married. Thus, extending the lifespan of men would benefit women. Using life sa...

We present a model for (not necessarily universal) quantum computation given in terms of a quantum neural network, based in turn on the interactions of Posner molecules, as described in a recent article by Matthew P. A. Fisher.

THE s'yndrome of glaucomatocycitic crises occupies a unique and important position among the many and heterogeneous types of glaucoma associated with uveitis. Its ominous onset, often highlighted by very high tension, is belied by the benign course it follows if treated with discretion. If the ophthalmologist is aware of this condition, he will be spared needless worry, and, more important, the...

Attention is the mechanism that allows us to selectively process the vast amount of information that we receive and to guide our behaviour. Visual spatial attention can be deployed overtly, accompanied by eye movements to the relevant location, or covertly, without eye movements (Helmholtz 1910/1925, Posner 1980).

A 56-year-old man with a rotator cuff injury, scheduled for arthroscopic reconstruction surgery, had a history of recurrent symptoms of eyeball pain and blurred vision for several years. After close examination, he was diagnosed with Posner-Schlossman syndrome. Three weeks before the scheduled surgery, his intraocular pressure (IOP) increased (> 30 mmHg) and he became extremely anxious about th...
