No limits on restriction

No Provable Limits Tòscientiic Knowledge'

In an article concerning problems that are impossible to solve exactly, but which can be computed in an average sense, J. F. Traub and H. Wozniakowski raised a challenge: \We believe it is time to up the ante and try to prove there are unanswerable scientiic questions. In other words, we would like to establish a physical GG odel's theorem.""1]. Out of this idea grew a workshop and computer sci...

No . 2596 COMFORT LIMITS FOR HEATECEILI NGSD

The purpose of the present study is to determine the limits of overhead radiation to which man in thermal neutrality can be exposed without feeling discomfort . Thermal neutrality for a person is defined as a condition in which he prefers neither a higher nor a lower ambient temperature level . Thermal neutrality is a necessary condition for a person to attain thermal comfort . However, this co...

Zeolite nanosystems: Imagination has no limits.

Fetal growth restriction at the limits of viability.

The outcome of early small-for-gestational age and/or intrauterine growth-restricted fetuses is reviewed. In these fetuses the outcome appears to be considerably poorer than that of appropriately grown fetuses and this seems mainly to be caused by intrauterine malnutrition rather than by hypoxemia. Active management of intrauterine growth restriction at the limits of viability may not be commen...

Restriction categories III: colimits, partial limits and extensivity

A restriction category is an abstract formulation for a category of partial maps, defined in terms of certain specified idempotents called the restriction idempotents. All categories of partial maps are restriction categories; conversely, a restriction category is a category of partial maps if and only if the restriction idempotents split. Restriction categories facilitate reasoning about parti...
