Contagion : How it spreads and How it can be stopped ?
Recent events have drawn attention to the issue of contagion. Dependencies among countries, including through trade links, will cause shocks to an individual country (or group of countries) to affect other countries, often on a regional basis. Such linkages are not contagion, but an increase in cross-market linkages after a shock to one country could be contagion. Weak countries’ economic funda...
متن کاملTraumatic brain injury: can the consequences be stopped?
Traumatic brain injury is a leading cause of morbidity and death in both industrialized and developing countries. To date, there is no targeted pharmacological treatment that effectively limits the progression of secondary injury. The delayed progression of deterioration of grey and white matter gives hope that a meaningful intervention can be applied in a realistic timeframe following initial ...
متن کاملCan the Salecker–wigner Clock Be Microscopic?
Title: Can the Salecker–Wigner clock be microscopic? Author: Andor Frenkel (Institute for Particle and Nuclear Physics, Bu-dapest, Hungary) Half a century ago H. Salecker and E. P. Wigner examined the functioning of a quantum clock of very simple construction [1]. They raised the question whether such a clock can be microscopic or not, but no clear-cut answer has been reached in [1] (see also [...

متن کاملDates from the molecular clock: how wrong can we be?
Large discrepancies have been found in dates of evolutionary events obtained using the molecular clock. Twofold differences have been reported between the dates estimated from molecular data and those from the fossil record; furthermore, different molecular methods can give dates that differ 20-fold. New software attempts to incorporate appropriate allowances for this uncertainty into the calcu...
