It is convenient to consider sexual problems according to their initial clinical presentation. They fall naturally into problems affecting primarily the male partner and those affecting primarily the female partner. When it comes to dealing with patients, however, it is a fundamental principle that both partners may be concerned in the aetiology of the disorder and both must be involved in trea...

The apparently haphazard way in which successive multiplications by a large integer K produce remainders after overflow makes the resulting numbers work surprisingly well for many Monte Carlo problems. Scores of papers have reported favorably on cycle length and statistical properties of such generators. The purpose of this note is to point out that all multiplicative congruential random number...

We examine the evaporation of a small black hole on a brane in a world with large extra dimensions. Since the masses of many Kaluza-Klein modes are much smaller than the Hawking temperature of the black hole, it has been claimed that most of the energy is radiated into these modes. We show that this is incorrect. Most of the energy goes into the modes on the brane. This raises the possibility o...
