A current growth industry is the organisation of meetings between scientists and those who are often referred to as 'soci-ety'. Behind the complicated but often stimulating discussions these meetings engender lies a profound schism between those close to science and technology and those who feel disenfranchised by it. There are many possible causes for this, including cryptic language, arroganc...

I am very pleased to support the nomination of Eric Fried-lander for the position of president of the American Mathematical Society. Eric has had an extremely distinguished career in our profession spanning almost four decades. Beyond a sterling research record his career is characterized by numerous and wide-ranging contributions to the mathematical enterprise. In my opinion his contributions ...

I n the body, some cells must sacrifi ce themselves for the greater good. Cell suicide (apoptosis) is essential for sculpting the body during development and for eliminating damaged or potentially dangerous cells that might cause disease. At his laboratory at New York University , Hyung Don Ryoo uses the fl y to study the molecular pathways that control apoptosis. His love for this model organi...

The public research sector is changing all over Europe. New semi-public research centers have emerged and now coexist with the traditional public research centers in the same organizational field. It is argued that these changes are mostly policy-driven and that the main mechanism is the emergence of new legitimation models of what research and research centers should be for, with a strong emph...

This paper is concerned with the null controllability of sys tems governed by semilinear parabolic equations The control is exerted either on a small subdomain or on a portion of the boundary We prove that the system is null controllable when the nonlinear term f s grows slower than s log jsj as jsj Introduction Assume a bounded and connected open set R with regular bound ary a nonempty open su...

This paper is based on study over twelve and a half years of 170 patients suffering from traumatic paraplegia or tetraplegia, ofwhom 162 survived for more than a month after injury, and of 103 patients with other lesions of the spinal cord. The patients in the second group were less suitable for analysis because in many the lesions were disseminated or incomplete: few could be compared with the...

A multidimensional version of the results of Koml os Ma jor and Tusn ady for the Gaussian approximation of the sequence of successive sums of independent random vectors with nite exponential moments is obtained Introduction The statement of the problem is well known It is required to construct on a probability space a sequence of independent random vectors X Xn with given distributions and a co...

Commentary Commentaire T he study of mortality among homeless women reported in this issue by Cheung and Hwang 1 (see page 1243) is a clarion call to our society and our health care community. The stunning 10-fold disparity in mortality rates between Toronto's homeless and housed women aged 18–44 is complemented by data from 7 other cities, which show that the risk of death among younger homele...
