Approximately 2 million persons in the United States have epilepsy, and 3 percent of persons in the general population will have epilepsy at some point in their lives. 1 In recent years, important advances have been made in the diagnosis and treatment o...

We derive the averaged equations describing a series array of Josephson junctions shunted by a parallel inductor-resistor-capacitor load. We assume that the junctions have negligable capacitance (β = 0), and derive averaged equations which turn out to be completely tractable: in particular the stability of both in-phase and splay states depends on a single parameter, δ. We find an explicit expr...

This article examines the development of the educational and vocational careers of 1257 subjects born between 1961 and 1969 as a function of economic circumstances in the Netherlands during the eighties. Subjects were expected to attend school longer in times of recession, to have a higher level of education, while getting a suitable, high-quality job (in terms of number of hours, appointment t...

ANOSA, VICTOR 0. Postsplenectomy blood values, marrow cytology, erythrocyte life-span, and sequestration in mice. Am. J. Physiol. 231(4): 1254-1257. 1976. -Studies in mice indicated that splenectomy influenced neither the erythrocyte and leukocyte total and differential values nor the erythrocyte survival. The right femoral marrow erythrocyte and nucleated cell counts were also not altered by s...

We reviewed the records of 1257 patients having 1625 total knee arthroplasties; all had pre-operative and postoperative perfusion lung scans and postoperative venograms which were classified as showing no thrombi, calf thrombi or proximal thrombi. Patients with calf thrombi were found to have a significantly greater risk for both symptomatic and asymptomatic pulmonary embolism compared with pat...

Seed longevity, a fundamental plant trait for ex situ conservation and persistence in the soil of many species, varies across populations and generations that experience different climates. Mondoni et al. (pp. 1257–1263) study seeds from alpine and lowland populations of Silene vulgaris and show that seed longevity has a genetic basis but may show strong adaptive responses, which are associated...

Physical inactivity is a public health problem in Saudi Arabia. A cross-sectional study was carried out to evaluate the pattern of physical activity, predictors of physical inactivity and perceived barriers to physical activity among health college students in King Khalid University. A total of 1257 students (426 males and 831 females) were recruited. The Arabic short form of the International ...
