Doppler echocardiography was used to measure stroke volume, peak flow velocity, and acceleration of flow in the ascending aorta in 10 healthy young volunteers during unlimited supine bicycle exercise and upright treadmill exercise. High quality studies were obtained in all subjects through the suprasternal notch acoustic window; there was no appreciable degradation in Doppler signal caused by i...

The seasonal variations in gravity wave (GW) vertical fluxes of zonal momentum and heat the mesopause region are calculated using nearly 10 years (from 2012 to 2021) temperature wind observations by a narrowband sodium lidar located Hefei, China (32°N, 117°E). Except summer, GW mostly westward, with ∼80% contributed short-period (10 min–1 hr) GWs, anticorrelate eastward wind. mean westward spri...

BACKGROUND The vacuolating cytotoxin and the cytotoxinassociated protein, encoded by vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori. OBJECTIVE The aim of this study was to perform vacA genotyping and evaluate its association with cagA genotype and clinical outcome. METHODS One hundred and twenty H. pylori strains were isolated from dyspeptic patient...

Current observations from a shelf sea, continental slopes and the abyssal North-East Atlantic Ocean are all dominated by the semidiurnal lunar (M2) tide. It is shown that motions at M2 vary at usually large barotropic and coherent baroclinic scales, >50 km horizontally and >0.5 H vertically. H represents the waterdepth. Such M2-scales are observed even close to topography, the potential source ...

Let M2 be the Igusa compactification of the Siegel modular variety of degree 2 and level 2. In earlier work with R. Lee, we carefully investigated this variety. Subvarieties Dl (compactification divisors) and H∆ (Humbert surface of discriminant 1) play a prominent role in its structure; in particular their fundamental classes span H4(M2;Z). We return to this variety and consider another class o...
