[1] A decade-long satellite altimeter data set is used to analyze the annual variations in the sea surface height (SSH) field northeast of the Hawaiian Islands. The annual harmonic amplitudes for the SSH and the along-island geostrophic flow are 2–4 cm and 2–4 cm s , respectively. Although these values are an order of magnitude smaller than the regional mesoscale eddy signals, the annual SSH si...

introduction: opiates cause dependency via affect on central nervous system. locus coeruleus nucleus is a main group of noradrenergic neurons in the brain that plays an important role in the expression of opioid withdrawal signs. during opioid withdrawal, brain waves change in addition to physical and behavioral signs. in this study, we examined the effects of locus coeruleus electrical stimula...

The effect of extracorporeal shock waves on hemoglobin release from red blood cells was recently found to be minimized under minute static excess pressure. It was proposed that this can be explained by shock wave-gas bubble interaction. We substantiated this further by two experiments by applying shock waves to suspended human RBC in a lithotripter at a lower frequency (1 pulse every 5 s) and b...

We experimentally demonstrate the generation of 1.024-Tb/s Nyquist-WDM phase-conjugated vector twin waves (PCTWs), consisting of eight 128-Gb/s polarization-division-multiplexed QPSK signals and their idlers, by a broadband polarization-insensitive fiber optic parametric amplifier. This novel all-optical signal processing approach to generate WDM-PCTWs enables a 2-fold reduction in the needed o...

Dynamic Brillouin gratings (DBGs), inscribed by comodulating two writing pump waves with a perfect Golomb code, are demonstrated and characterized experimentally. Compared with pseudo-random bit sequence (PRBS) modulation of the pump waves, the Golomb code provides lower off-peak reflectivity due to the unique properties of its cyclic autocorrelation function. Golomb-coded DBGs allow the long v...

the velocity data of seismic waves in a region has an important role in locating occurred events. information such as velocity ratio of vp/vs and velocity curves for pg, pn, sg, and sn phases directly affect the locating results. it is well known that the vp/vs ratio can be used to predict lithology, and that s-waves are sensitive to microcracks aligned by the present day stress field. also, th...

Paucisynaptic connections between n. lateralis posterior (LP) and dorsal hippocampus (Hip) have been demonstrated in acute experiments. In the free moving cats, with chronic implanted electrodes on the neocortex, in LP, pulvinar (Pul), VA and VL nuclei of the thalamus and in the dorsal hippocampus (Hip), the theta waves recorded in LP, Pul and Hip were not of the same frequency and origin. In w...

Slow waves are known to originate orally in the stomach and to propagate toward the antrum, but the exact location of the pacemaker and the precise pattern of propagation have not yet been studied. Using assemblies of 240 extracellular electrodes, simultaneous recordings of electrical activity were made on the fundus, corpus, and antrum in open abdominal anesthetized dogs. The signals were anal...

The Sommerfeld factor for arbitrary partial wave processes is derived in the non-relativistic limit. The s-wave and p-wave numerical results are presented for the case of Yukawa interactions. An approximate analytic expression is also found for the Sommerfeld factor of Yukawa interactions with arbitrary partial waves, which is exact in the Coulomb limit. It is demonstrated that this result is a...

The purpose of this study is to demonstrate the feasibility of kinematic MR imaging in visualizing peristaltic activity in the reconstructed gastrointestinal tract with quantitative measurements. Sixteen patients with gastrointestinal reconstruction were studied with kinematic MR imaging using HASTE and/or true FISP. Peristaltic waves were noted in the retrosternal gastric segment after gastric...
