It has been proposed that the capacity to code the 'like me' analogy between self and others constitutes a basic prerequisite and a starting point for social cognition. It is by means of this self/other equivalence that meaningful social bonds can be established, that we can recognize others as similar to us, and that imitation can take place. In this article I discuss recent neurophysiological...

Coronary pressure-flow relations during autoregulated and vasodilated flow states were compared between eight dogs with renovascular hypertension and left ventricular hypertrophy and 12 normal dogs. Each relation was constructed from serial steady-state measurements of end-diastolic coronary pressure and flow during perfusion of the circumflex artery by an extracorporeal circuit at controlled d...

Although in situ end-systolic pressure-volume relations (ESPVRs) are approximately linear throughout a limited load range, they often yield seemingly "1negative" volume axis intercepts (V0) and V0 shifts with inotropic interventions. We tested whether or not these findings could stem from in situ ESPVR nonlinearity, and we examined the physiologic meaning and limitations of linearized ESPVR var...

Diastolic function of the left ventricle was analysed in patients with different cardiac diseases: acute and chronic volume overload (in aortic and mitral incompetence), pressure overload and inappropriate ventricular hypertrophy (aortic stenosis and hypertrophic cardiomyopathy), congestive cardiomyopathy, and constrictive pericarditis. Most patients were receiving digitalis therapy at the time...

PVT relations in liquid and solid T2 near the melting curve were measured over 20.5 K-22.1 K and 0 MPa-7 MPa (0 bar-70 bar) with a cell that used diaphragms for pressure and volume variation and measurement. Because of ortho-para self conversion, the melting pressure Pm and the liquid molar volume Vlm increased with time. The rates were consistent with a second order reaction similar to that fo...

The exponential fall of the pulmonary pressure curve from its systolic peak to left atrial pressure previously described in the presence of normal intraventricular conduction has been investigated in patients with right bundle-branch block. We have been able to show once more that the pulmonary artery diastolic pressure seeks the left atrial level: when right ventricular systole is delayed the ...

Introduction: the EU and national industrial relations A paradox has emerged in the last two decades in Europe. Interest in comparing employment relations has increased, under international pressure to increase productivity, employment rates and competitiveness and to attract foreign investors and foreign skilled workers. International organisations, governments, trade unions, multinational com...

Using the Fresnel relations as axioms, we derive a generalized electromagnetic momentum for a piecewise homogeneous medium and a different generalized momentum for a medium with a spatially varying refractive index in the Wentzel-Kramers-Brillouin (WKB) limit. Both generalized momenta depend linearly on the field, but the refractive index appears to different powers due to the difference in tra...

BACKGROUND AND PURPOSE The pressure-flow relation has been characterized in normal cerebrum, but it has not been studied in cerebrum dependent on collateral flow. The purpose of this investigation was to examine the relation between systemic pressure, regional cerebral blood flow, and middle cerebral artery branch pressure in collateral-dependent and normal brain. METHODS In 10 anesthetized d...
