Steve Simpson was born and grew up in Australia. After completing his undergraduate degree at the University of Queensland, he travelled to London where he undertook his PhD on locust feeding physiology. Steve then spent 22 years in Oxford, fi rst in Experimental Psychology and then in the Department of Zoology and the Natural History Museum, before being enticed back to Australia in 2005. Toge...

Fuzzy Newton-Cotes method for integration of fuzzy functions that was proposed by Ahmady in [1]. In this paper we construct error estimate of fuzzy Newton-Cotes method such as fuzzy Trapezoidal rule and fuzzy Simpson rule by using Taylor's series. The corresponding error terms are proven by two theorems. We prove that the fuzzy Trapezoidal rule is accurate for fuzzy polynomial of degree one and...

Simpson introduced the lattice P of Π 1 classes under Medvedev reducibility. Questions regarding completeness in P are related to questions about measure and randomness. We present a solution to a question of Simpson about Medvedev degrees of Π 1 classes of positive measure that was independently solved by Simpson and Slaman. We then proceed to discuss connections to constructive logic. In part...

The history of medicine division of the National Library of Medicine has in its manuscripts collection a body of correspondence that vividly describes the strong views held by James Y Simpson in espousing the use of obstetric anaesthesia. The collection consists of 31 letters written by Simpson, mostly from Edinburgh, to the London obstetrician Francis Henry Ramsbotham during the years 1844-53 ...

Recent progress in the theoretical treatment of electronically nonadiabatic processes is discussed. First we discuss the generalized Born-Oppenheimer approximation, which identifies a subset of strongly coupled states, and the relative advantages and disadvantages of adiabatic and diabatic representations of the coupled surfaces and their interactions are considered. Ab initio diabatic represen...
