Case 1, a white male aged 42, was first seen in July, 1943, suffering from secondary syphilis. He was admitted to hospital and was treated with twice weekly injections of N.A.B. and bismuth (total 4 5 g. and 1 2 g. respectively); 4 months later he had become sero-negative but he was given a second course of injections in November/December, 1943 (Mapharside 0-5 g. and bismuth 1-2 g.). Further S....

We re–investigate the construction of half–supersymmetric seven–brane solutions of IIB supergavity. In contrast to previous approaches we allow the occurrence of objects with monodromy Tr Λ 6= 2. We obtain non-trivial information from the requirement of a globally well–defined Killing spinor and by including SL(2,Z)–invariant source terms.

The purpose of this presentation is to introduce both the concept of risk and the precautionary principle, that is a major policy principle in present-day risk management. Since risk has been the subject of many misconceptions I will do this in large part by criticizing seven views on risk that I believe to have caused considerable confusion both among scientists and policy-makers. But before l...

During the last several years, a large class of computer programs, called “ Intelligent Agents” (IAs), has emerged as a result of intensive research efforts in various countries. There is ongoing discussion how to classify the individual types of intelligent agents and how to distinguish between them and a subclass called “Sapient Agents” (SAs). In this paper, seven approaches are proposed to d...

My problem is that I have been persecuted by an integer. For seven years this number has followed me around, has intruded in my most private data, and has assaulted me from the pages of our most public journals. This number assumes a variety of disguises, being sometimes a little larger and sometimes a little smaller than usual, but never changing so much as to be unrecognizable. The persistenc...

0. Introduction When the Handbook of Integer Sequences came out in 1973, Philip Morrison gave it an enthusiastic review in the Scientific American and Martin Gardner was kind enough to say in hisMathematical Games column for July 1974 that “every recreational mathematician should buy a copy forthwith.” That book contained 2372 sequences. Today the On-Line Encyclopedia of Integer Sequences (or O...

as this does nothing to support the thesis that the members of the two tribes share any important moral beliefs and would not help the absolutist in arguing against relativism. The claim of the absolutist about the Crow and the . . thing is not at all clear. If the relativist contention is expressed as “what is right and what is wrong varies fiom culture to culture,” then whether we are to asse...

Sik,?It was with great interest that I read in J01'1 issue Colonel Wimberley's article on the out iea Dengue-like fever amongst the 15tli Sikhs, It struck me that if there is a differential diagnosis a < between ' Breakbone Dengue ' and the Seven-Day I e\ei c cribed by Major Leonard Rogers?then these interesting cases must fall under the latter heading?and this, in spi e the fact that the fever...
