BACKGROUND High-risk human papillomavirus (hrHPV) testing has higher sensitivity but lower specificity than cytology for cervical (pre)-cancerous lesions. Therefore, triage of hrHPV-positive women is needed in cervical cancer screening. METHODS A cohort of 1,100 hrHPV-positive women, from a population-based screening trial (POBASCAM: n = 44,938; 29-61 years), was used to evaluate 10 triage st...

BACKGROUND Exercise training is of benefit for patients with restrictive lung disease. However, it tends to be intolerable for those with severe disease. We examined whether providing ventilatory assistance by using negative pressure ventilators (NPV) during exercise training is feasible for such patients and the effects of training. METHODS 36 patients with restrictive lung disease were pros...

ABSTRACT: We report on a strategy for achieving negative phase velocity (NPV) in a homogenized composite medium (HCM) conceptualized using the Bruggeman formalism. The constituent material phases of the HCM do not support NPV propagation. The HCM and its constituent phases are isotropic dielectric–magnetic mediums; the real parts of their permittivities/permeabilities are negative–valued wherea...

We generalize the hyper-systolic algorithm proposed in [1] for abstract data structures on massive parallel computers with np processors. For a problem of size V the communication complexity of the hyper-systolic algorithm is proportional to √ npV , to be compared with npV for the systolic case. The implementation technique is explained in detail and the example of the parallel matrix-matrix mu...
