Cracks, joints, fluids, and other pore-scale structures have long been hypothesized to be the cause of the large elastic nonlinearity observed in rocks. It is difficult to definitively say which pore-scale features are most important, however, because of the difficulty in isolating the source of the nonlinear interaction. In this work, we focus on the influence of cracks on the recorded nonline...

Since isospin symmetry is only approximate, the discrepancy in this relation, D ; fCEX 2 sf1 2 f2dy p 2, is expected to be nonzero. Interesting physics lies in the violation of this relation beyond effects due to the hadronic mass differences and the Coulomb interaction. It is the purpose of this Letter to demonstrate that recent experimental data at low energies require a residual contribution...

The P wave of the electrocardiogram has been investigated in great detail in normal subjects (Shipley and Hallaran, 1936; Graybiel et al., 1944; Stewart and Manning, 1944; Thomas and Dejong, 1954) and in various types of cardiac disease (Wood and Selzer, 1939; Thomas and Dejong, 1954; Martins de Oliveira and Zimmerman, 1959). There have been few studies of the P wave in hypertension, however, a...

Title: Unfiltered signal averaged P wave analysis-further validation of the method Authors:

BACKGROUND Detection of characteristic waves, such as QRS complex, P wave and T wave, is one of the essential tasks in the cardiovascular arrhythmia recognition from Electrocardiogram (ECG). METHODS A multiscale morphological derivative (MMD) transform-based singularity detector, is developed for the detection of fiducial points in ECG signal, where these points are related to the characteris...

We consider a single impurity immersed in a Fermi sea close to an interspecies p-wave Feshbach resonance. We calculate its dispersion and spectral response to a radio frequency pulse. In a magnetic field, dipolar interactions split the resonance and two novel features with respect to the s-wave case appear: a third polaron branch in the excitation spectrum, in addition to the usual attractive a...

We have produced and detected molecules using a p-wave Feshbach resonance between 40K atoms. We have measured the binding energy and lifetime for these molecules and we find that the binding energy scales approximately linearly with the magnetic field near the resonance. The lifetime of bound p-wave molecules is measured to be 1.0+/-0.1 ms and 2.3+/-0.2 ms for the ml=+/-1 and ml=0 angular momen...
