Compressed sensing enables the acquisition of sparse signals at a rate that is much lower than the Nyquist rate. Compressed sensing initially adopted [Formula: see text] minimization for signal reconstruction which is computationally expensive. Several greedy recovery algorithms have been recently proposed for signal reconstruction at a lower computational complexity compared to the optimal [Fo...

Inflation and the Current Bargaining Climate With inflation rates high and recovery rates low, it should not be surprising that many unions are interested in improving their COLA clauses. The most common COLA formula calls for a wage-rate increase of one cent per hour for each 0.3 point change in the price index. Under such a formula it may be impossible to prevent erosions in real wages. Suppo...

OBJECTIVE To investigate the differences in four formulae for heart rate correction of the QT interval in serial ECG recordings in healthy children undergoing a graded exercise test. SUBJECTS 54 healthy children, median age 9.9 years (range 5.05-14.9 years), subjected to graded physical exercise (on a bicycle ergometer or treadmill) until heart rate reached > 85% of expected maximum for age. ...

6-min walk tests (6MWT) are routinely performed in patients with chronic obstructive pulmonary disease (COPD). Oxygen uptake ([Formula: see text]) kinetics during 6MWT can be modeled and derived parameters provide indicators of patients' exercise capacity. Post-exercise [Formula: see text] recovery also provides important parameters of patients' fitness which has not been extensively investigat...

Intracellular pH (pHi) and its basolateral regulation were studied in isolated proximal-proximal and distal-proximal segments of garter snake ( Thamnophis spp.) renal tubules with oil-filled lumens in HEPES-buffered and in HEPES-[Formula: see text]-buffered media (pH 7.4 at 25°C). pHi was measured with the pH-sensitive fluorescent dye 2',7'-bis(2-carboxyethyl)-5,6-carboxyfluorescein (BCECF) und...
