Pulmonary thromboembolism: a retrospective study on the examination of 991 patients by ventilation/perfusion SPECT using Technegas

Nuklearmedizin, 2001
Summary Purpose: Conventional planar ventilation/perfusion (V/P)- imaging in those patients suspected of suffering from pulmonary thromboembolism (PTE) is of limited diagnostic value. It is the purpose of this retrospective study to determine whether the

The peculiar type I supernova in NGC 991.

, 1985
A spectrum of the recent supernova SN 1984l in NGC 991 taken near maximum light is presented. The spectrum is very similar to that of SN 1983n in M83, thus establishing a class of precisely defined peculiar Type I supernova.

Impact of end‐capped engineering on the optoelectronic characteristics of pyrene‐based non‐fullerene acceptors for organic photovoltaics

International Journal of Quantum Chemistry
Pyrene‐based molecules are being explored as prospective fullerene‐free acceptors for organic solar cells (OSCs), due to their easy accessibility, structural planarity, and excellent electron delocalization.

11% Efficient Perovskite Solar Cell Based on ZnO Nanorods: An Effective Charge Collection System

, 2014
A perovskite solar cell based on ZnO nanorods was prepared, and its photovoltaic performance was investigated. ZnO nanorods were grown on the ZnO seed layer from solution, and their diameters and lengths were controlled by precursor concentration and ...

Full crop protection from an insect pest by expression of long double-stranded RNAs in plastids

Science, 2015
Bypassing a plant's defense for pest defense Colorado potato beetles can skeletonize the leaves on a potato plant, devastating crop yields. Insecticides are increasingly useless as the beetle evolves resistance. Zhang et al. used RNA interference to take

Variation of sensitivity, specificity, likelihood ratios and predictive values with disease prevalence by H. Brenner and O. Gefeller, Statistics in Medicine, 16, 981-991 (1997)

Statistics in Medicine, 1998
Recently, Brenner and Gefeller presented calculations in which the basic efficacy measures of diagnostic tests, sensitivity, specificity and likelihood ratios, vary strongly with disease prevalence. The calculations are based upon the situation where the
