Receiver functions derived from teleseismic body waves recorded by ocean-bottom seismometers on the southern East Pacific Rise reveal shear waves converted from compressional waves at the mantle discontinuities near 410- and 660-kilometer depth. The thickness of the mantle transition zone between the two discontinuities is normal relative to the global average and indicates that upwelling benea...

Scenario: The following ECG waveform was obtained in an 85-year-old male patient admitted to the telemetry unit for evaluation of syncope. His pertinent medical history includes hypertension, coronary artery disease, and prior inferior/lateral myocardial infarction (MI). ECG PUZZLER A regular feature of the American Journal of Critical Care, the ECG Puzzler addresses ECG interpretation for clin...

Scenario: The patient is a 52-year-old woman who presents to her physician’s office with complaints of general malaise and a low-grade fever. The patient presented to an acute care clinic 3 weeks prior for a sore throat, which was diagnosed as strep throat (streptococcal pharyngitis). Appropriately, she was started on oral penicillin but admitted to not finishing the prescription since she “fel...

in the present work properties of rossby and inertia gravity waves are investigated based on proper orthogonal decomposition (pod) functions. the pod functions are constructed using analytical, experimental or numerical data recorded as snapshots. the pod basis can be carried out to make a reduced order model by galerkin projection of governing equations onto these functions. in this paper, the...

We present a method for simulating local water waves caused by obstacles in water streams for real-time graphics applications. Given a low-resolution water surface and velocity field, our method is able to decorate the input water surface with high resolution detail for the animated waves around obstacles. We construct and animate a vector representation of the waves. It is then converted to fe...

Electric dipole radiation consists of traveling and evanescent plane waves. When radiation is detected in the far field, only the traveling waves will contribute to the intensity distribution, as the evanescent waves decay exponentially. We propose a method to spatially separate the traveling and evanescent waves before detection. It is shown that when the radiation passes through an interface,...
