During the first 2 years of Geoffrey Harris’ tenure as Fitzmary Professor of Physiology, University of London (1952–1962), I was one of the four fellows in his laboratory based in the ‘Huts’, two prefabricated buildings on the grounds of Maudsley Hospital, South London. Peter Fawcett, a later collaborator, remarked, ‘It was an enigma to me why this eminent man should be stuck in a bunch of ex-a...

A case of hereditary angio-oedema is described together with the family history and manifestations in the father of the patient. The problems encountered in his management are discussed, including tracheostomy and genetic counselling.

background: intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. dynamic hip screw (dhs) is still considered the gold standard for treating intertrochanteric fractures by many. not many studies compare the dhs with proximal femoral nail (pfn), in type ii intertrochanteric ...

One way to optimize social learning is to be selective when choosing from what sources to accept information. Preschoolers prefer to learn from previously accurate or competent sources, rather than from unreliable ones (e.g., Koenig, Clément, & Harris, 2004). The current study extends this work by comparing the ability to monitor an actor’s success in two species: children and chimpanzees. Memb...

When my son Jason was an economics Ph.D. student at Harvard in the 1990s, he said: “I have observed that only two economists can push you around, Milton Friedman and Gary Becker.” I agreed but argued that it was a good thing. Everyone needed heroes, and Gary had only Milton. Milton had no one, except Ronald Reagan in the 1980s, but Reagan did not really qualify as an economist. Arthur Burns may...

The last decade has witnessed many clever constructions of parameterized families of pairing-friendly elliptic curves that now enable implementors targeting a particular security level to gather suitable curves in bulk. However, choosing the best curves from a (usually very large) set of candidates belonging to any particular family involves juggling a number of efficiency issues, such as the n...
