The artery pulsation has a strong correlation with the blood flow in the newborn baby head and tissuemotion has a relationship with artery pulsation. In this paper, we propose a novel method to estimate the tissuemotion quantitatively by combining local and global motion estimation methods, namely combined local-global (CLG) optical flow technique in cranial ultrasonogram of newborn babies. Tis...

Bombardier beetles (Brachinini) use a rapid series of discrete explosions inside their pygidial gland reaction chambers to produce a hot, pulsed, quinone-based defensive spray. The mechanism of brachinines' spray pulsation was explored using anatomical studies and direct observation of explosions inside living beetles using synchrotron x-ray imaging. Quantification of the dynamics of vapor insi...

the linear adiabatic pulsation-periods of mira variable stars have been derived. approximately 2701[1]models were calculated for m = 0.7 mθ to 2 mθ stars with radii from 180 rθ to 340 rθ and luminosities from 2800 lθ to 10,000 lθ. the chemical composition of all models is (x,z) = (0.7,0.02). from the result of this study, linear relations on luminosity-period-mass relationship and luminosity-pe...

were uniform and roundish with visible pulsation. On palpation the skin was freely movable over them, and the pulsation was found to be expansile. Pulsation was practically abolished by pressure of the superficial temporal artery over the zygoma. On keeping up this pressure and again palpating, it was found that the sacs could not be emptied, were resistant to pressure, and fairly freely movabl...

A new precise method for measuring magnetic fields on Zeeman plates of the southern cepheid W Sgr is reviewed. Ten plates over the 7_6 period of pulsation show two extrema in the measured values of the effective magnetic field. The method has a precision of ±0.4_ in the Zeeman shift corresponding to ±50 gauss (g). A negative "spike" of -220g occurred at the time of arrival of the compressional ...

Intraoperative spinal sonography was used during cervical anterior approach procedures for cervical discectomy and osteophytectomy to demonstrate spinal pulsation, the protruded disc or osteophyte, the anterior subarachnoid space, and the spinal cord. Spinal pulsation was recognized in some cases before removal of the disc but the anterior subarachnoid space and spinal cord could not be observe...

was marked, and gave the impression of a large vessel. In the three boys' cases?aged respectively six, ten and eleven years? nasal obstruction, with enlarged tonsils and adenoids, existed. In one of the boys the pulsation was bilateral and very marked, communicating a heaving impulse to the left tonsil, which was hypertrophied. Connal reminds us that most observers have ascribed the pulsation t...

Three presumptive cardiac tissues from aborted human embryos which ranged in length from 2 mm to 4 mm and in age from 53 days to 71 days were maintained in culture beating rhythmically for 18-88 days. Medium renewal, temperature increases (from 31° to 38°C), and pH increases (from 6.92 to 7.75) raised the pulsation rate. Excess potassium stopped the pulsation. Sympathomimetic drugs increased th...

It has long been known that rotation can have an appreciable impact on stellar pulsation — by modifying the usual p and g modes found in the non-rotating case, and by introducing new classes of mode. However, its only relatively recently that advances in numerical simulations and complementary theoretical treatments have enabled us to model these phenomena in any great detail. In this talk I’ll...
