The Slight Surprise of Integration
Western hospitals of some size are characterized by a proliferation of nonintegrated information systems, resulting in considerable frustration both among users and information technology personnel. Consequently there have been many integration efforts. Such efforts typically include some or all of the four principle classes of hospital-based systems: electronic patient records, laboratory syst...
متن کاملA Slight Sharpening of LMN
Linial, Mansour and Nisan [7] proved that a function computed by a small-depth circuit of limited size has most of its Fourier support on small sets. We improve their bounds. When the bottom fanin is bounded we use essentially their argument, but to reduce the general case to this case without a loss in the asymptotic bounds requires a new argument. Warning: Essentially this paper is accepted f...
متن کاملGuided Waves in Slight, Azimuthally
A method of calculating dispersion curves for guided waves in slight, azimuthally anisotropic formations is developed with perturbation theory. The fluid is assumed to be inviscid, the formation perfectly elastic and homogeneous, and the ·borehole wall cylindrical. The first step is calculating the elastic moduli for a transversely isotropic formation whose moduli are close to those for the azi...
متن کاملCardiovascular risk perception in women: true unawareness or risk miscalculation?
Assessing the 'accuracy' of cardiovascular risk perception is a worthy scientific goal that may lead to targeted interventions aimed at improving risk communication and health outcomes. Current cardiovascular risk scores, however, have shown poor calibration when used in populations that differ temporally and/or geographically from the derivation sample, limiting their reliability as the refere...
متن کاملElectrocardiographic patterns in slight coronary attacks.
The seriousness of cardiac infarction can be assessed on clinical grounds. Prolonged pain refractory to morphia, severe shock with fall of blood pressure to dangerous levels, and the early onset of cardiac failure are unequivocal signs of a severe attack. In many patients regarded as suffering from cardiac infarction there are none of these signs, and the diagnosis is based on coronary pain acc...
