Sudden death is well documented as an unexpected occurrence in trained long distance runners, skiers, and swimmers.”2 On post-mortem examination in such cases, the abnormal findings may include unsuspected congenital anomalies or unrecognized coronary atherosclerosis or cardiomyopathy. In many cases, no abnormality is found, and here, recourse for an explanation involves the prevalence of cardi...

Intravascular haemolysis has been found to result from prolonged endurance competition, rigorous military training and participation in impact sports. Haematological research involving the recreational runner is sparse. Recreational runners frequently vary their training to avoid monotony and improve endurance capacity. This study investigated the haematological effects of a typical day of incr...

Parkinson's disease is characterized by α-synuclein pathology in the form of Lewy bodies and Lewy neurites. Braak et al described the spatial and temporal spread of α-synuclein pathology in Parkinson's disease. Recent experimental studies have demonstrated that α-synuclein can transfer from cell to cell. In this review, we highlight the involvement of α-synuclein in Parkinson's disease and in B...

The Lonely Runner Conjecture of J. Wills asserts the following. For any vector v ∈ (R−{0})n−1 there exists t ∈ R such that every component of tv has distance at least 1/n to the nearest integer. We study those vectors v for which the bound of this conjecture is attained. In particular, we construct an infinite family of such tight vectors. This family, plus three sporadic examples, constitute a...

Exclusive patents sacrifice product competition to provide firms incentives to innovate. We characterize an alternative mechanism whereby later inventors are allowed to share the patent if they discover within a certain time period of the first inventor. These runner-up patents increase social welfare under very general conditions. Furthermore, we show that the time window during which later in...

Abstract In this note we develop a linear programming framework to produce upper and lower bounds for the lonely runner problem.

With the increase in jogging and distance running as a means of attaining and maintaining fitness, and in the light of the difficulty in advising certain groups of patients about their capacity for such exercise, we report on several potentially avoidable factors in the death of a 45 year old Sheffield Marathon runner in June 1983.

This is an introduction to a probabilistic model for the arithmetic of elliptic curves, a model developed in a series of articles of the author with Bhargava, Kane, Lenstra, Park, Rains, Voight, and Wood. We discuss the theoretical evidence for the model, and we make predictions about elliptic curves based on corresponding theorems proved about the model. In particular, the model suggests that ...

This article will present what we know of the life and times of an important alchemist, Ibn Umayl. It is entitled ‘Towards a Context’ because I have not yet consulted a number of his treatises, which are mostly only available as manuscripts. Ibn Umayl’s position in alchemy accords with Hermetic doctrines, and may have developed as a traditionalist reaction to developments in alchemy around the ...
