J wave is getting more and more important in the clinical diagnosis as a new index of the electrocardiogram (ECG) of ventricular bipolar, but its signal often mixed in normal ST segment, using the traditional electrocardiograph, and diagnosed by experience cannot meet the practical requirements. Therefore, a new method of multilayer nonnegative matrix factorization (NMF) in this paper is put fo...

A large eddy simulation (LES) is used to explore the effects of high frequency actuation on a wall-mounted hump geometry. Low frequency forcing at F ∼ O(1) has been shown to increase entrainment through regular shedding of large-scale structures. Using a LES technique previously validated on the baseline and controlled flow over the wall-mounted hump geometry, the effectiveness of high frequenc...

Two related problems on scalar (2+1)-dimensional solitons in a saturable nonlinear medium are investigated. The first one is the internal oscillations of fundamental (single-hump) solitons. Internal modes which cause these oscillations, both with and without angular dependence, are discovered. The visual effect of angle-dependent internal modes on the soliton can be a rotation or spatially unev...

Recent studies on Laffer curves (tax revenue curves) find that the curve for consumption tax might not be hump-shaped, but monotonically increasing, whereas labor income is hump-shaped. This study investigates cause of this difference in shapes two curves, by decomposing effects an increase a rate base as product parts: (i) relative price leisure (RPL), and (ii) substitution effects. It shown f...

DOI: 10.1590/S1679-45082015AI2979 NRS, a woman, 71-year-old, who born in São Paulo, Brazil, sought our care service complaining of progressive low visual and metamorphopsia in the right eyes (RE) for 3 months. She had no-history of comorbidities, ophthalmologic surgeries or eye diseases. Upon examination her best-corrected visual acuity was 20/80 in the RE and 20/20 in the left eye. Funduscopy ...

In this paper we consider the entry and exit of firms in a Ramsey model with capital and an endogenous labour supply. At the firm level, there is a fixed cost combined with increasing marginal cost, which gives a standard U-shaped cost curve with optimal firm size. The costs of entry (exit) are quadratic in the flow of new firms. The number of firms becomes a second state variable and the entry...

Charge movement was measured in frog cut twitch fibers with the double Vaseline gap technique. Five manipulations listed below were appl ied to investigate their effects on the hump component (Iv) in the ON segments of TEST minus CONTROL current traces. When external CIwas replaced by MeSO~ to eliminate CI current, I v peaked earlier due to a few millivolts shift of the voltage dependence of I ...

Background The goals of Scoliosis Specific Schroth Physiotherapy (SSSPT) are to restore muscle balance, reshape the rib cage and reduce the rib hump to improve the esthetic of the patient, to increase the breathing areas and vital capacity, to reduce the Cobb angles, and to avoid spinal fusion surgery. Measuring the Cobb angles on P-A radiographs, assessing the sagittal profile on lateral radio...

This paper studies the evolution of life satisfaction over the life course in Germany. It clarifies the causal interpretation of the econometric model by discussing the choice of control variables and the underidentification between age, cohort and time effects. The empirical part analyzes the distribution of life satisfaction over the life course at the aggregated, subgroup and individual leve...
