Abstract We prove a general estimate for the Weyl remainder of an elliptic, semiclassical pseudodifferential operator in terms volumes recurrence sets Hamilton flow its principal symbol. This quantifies earlier results Volovoy (Comm Partial Differential Equations 15:1509–1563, 1990; Ann Global Anal Geom 8:127–136, 1990). Our result particularly improves exponents compact Lie groups and surfaces...

Objectives: 1to evaluate the ability of the power spectrum of brain electrical activity to discriminate between age matched normal children and children diagnosed as learning disabled (LD) and, 2to correlate brain electrical activity with intelligence, school achievement and neuropsychological performance test scores. Methods: Electrical potentials (EEG) were recorded from 19 channels in a rest...

Photoplethysmogram (PPG) monitoring is not only essential for critically ill patients in hospitals or at home, but also for those undergoing exercise testing. However, processing PPG signals measured after exercise is challenging, especially if the environment is hot and humid. In this paper, we propose a novel algorithm that can detect systolic peaks under challenging conditions, as in the cas...

A 'mole' at the Bristol Royal Infirmary tells me that at the last Hospital Committee Meeting it was explained to the assembled consultants that under the rules of the new Special Trust, when they have fulfilled the Provider contract for the number of patients to be seen in a particular week, they will not be allowed to see any more.
