The death occurred on the 2nd November, at 4-59 a.m. at his residence, in the little village of Ayot St. Lawrence, of this great man of arts, letters, philosophy, satire and controversy, at the ripe old age of 94. In living to this age, G. B. S. divorced age from senility successfully. Our interest no. 1 lies in recording this fact. Longevity without senility is the objective of to-day's medici...

As measured by the pace of city growth in western Europe from 1000 to 1800, absolutist monarchs stunted the growth of commerce and industry. A region ruled by an absolutist prince saw its total urban population shrink by one hundred thousand people per century relative to a region without absolutist government. This might be explained by higher rates of taxation under revenue-maximizing absolut...

Several mathematical models of tumor growth are now commonly used to explain medical observations and predict cancer evolution based on images. These models incorporate mechanical laws for tissue compression combined with rules for nutrients availability which can differ depending on the situation under consideration, in vivo or in vitro. Numerical solutions exhibit, as expected from medical ob...

The authors’ purpose in this study was to identify social structural predictors of receiving emotional support from parents early in life and structural factors responsible for variations in the associations between early parental support and adult health status. Data from a US representative sample of 2,786 adults aged 25–74 years suggest that men, non-Whites, and individuals from socioeconomi...

Various models of tumor growth are available in the litterature. A first class describes the evolution of the cell number density when considered as a continuous visco-elastic material with growth. A second class, describes the tumor as a set and rules for the free boundary are given related to the classical Hele-Shaw model of fluid dynamics. Following the lines of previous papers where the mat...

Preface One of the most influential works in Fluid Dynamics at the edge of the 19-th century was a short paper [130] written by Henry Selby Hele-Shaw (1854–1941). There Hele-Shaw first described his famous cell that became a subject of deep investigation only more than 50 years later. A Hele-Shaw cell is a device for investigating two-dimensional flow of a viscous fluid in a narrow gap between ...
