The 1992 magnitude 7.3 Landers earthquake triggered an exceptional number of additional earthquakes within California and as far north as Yellowstone and Montana. Since this observation, other large earthquakes have been shown to induce dynamic triggering at remote distances--for example, after the 1999 magnitude 7.1 Hector Mine and the 2002 magnitude 7.9(More)
It remains unknown how the small strains induced by seismic waves can trigger earthquakes at large distances, in some cases thousands of kilometres from the triggering earthquake, with failure often occurring long after the waves have passed. Earthquake nucleation is usually observed to take place at depths of 10-20 km, and so static overburden should be(More)
Replication-defective mutants of herpes simplex virus type 1 (HSV-1) may prove useful as vectors for gene transfer, particularly to nondividing cells. Cgal delta 3 is an immediate-early gene 3 (IE 3) deletion mutant of HSV-1 that expresses the lacZ gene of Escherichia coli from the human cytomegalovirus immediate-early control region but does not express(More)
The conventional wisdom is that postwar economic growth has been unpredictable. In the 1960s few observers accurately forecast which countries would grow quickly. In this paper we show that indexes of social development constructed in the early 1960s have considerable predictive power. These results indicate the importance of ''social capability'' for(More)
Derivatives of herpes simplex virus type 1 (HSV-1) have elicited considerable interest as gene transfer vectors because of their ability to infect a wide range of cell types efficiently, including fully differentiated neurons. However, it has been found that infection of many types of cell with vectors derived from replication-defective mutants of HSV-1 is(More)
W hy does income grow faster in some countries than others? Most empirical research addressing this question has in common that only a few explanatory variables are considered, but differs in the variables selected (e. Temple 2005). Researchers select explanatory variables because there are almost as many candidate variables as countries, and classical(More)
The aim of this study was to quantify the incidence of complications following inguinal herniotomy in small babies weighing 5 kg or less. This was a retrospective review of inguinal herniotomies performed in our unit between December 1997 and March 2002 on babies weighing 5 kg or less. A total of 154 patients underwent hernia repair, of which 125 patients(More)
Results are reported of the first systematic study of anomalous nonlinear fast dynamics and slow dynamics in a number of solids. Observations are presented from seven diverse materials showing that anomalous nonlinear fast dynamics (ANFD) and slow dynamics (SD) occur together, significantly expanding the nonlinear mesoscopic elasticity class. The materials(More)
