3D seismic reflection data have been used to map 784 enigmatic ridge-furrow structures in water depths of 0.8–1.7 km offshore Angola. The are characterised by asymmetric ridges with intervening furrows, typically <0.5–5.5 long, a sinuous bifurcating planform. furrows well-imaged on profiles, and range from 60 80 m width, up 10 amplitude, 0.1–1 wavelength. furrow sets aggrade downslope direction...

examining the role of glaze \vare pottery in the social lives of the late precontact and early contact Pueblos. By tracing the circulation of spe­ cialized knowledge, raw materials, and the glaze-painted pots themselves, through interactive networks ofvarying sizes and scales, these researchers reveal how glaze ware production, distribution, and use articulated with a variety of dynamic histori...

OBJECTIVE To estimate the prevalence of metabolic syndrome by age, sex, and diabetes status in Northern Plains and Southwest American Indians. RESEARCH DESIGN AND METHODS Data for this analysis came from the Education and Research Toward Health (EARTH) study, a 5-year cross-sectional study of Southwest and Northern Plains American Indian adults. The National Cholesterol Education Program's Ad...

We report the unprecedented Lapita exploitation and subsequent extinction of large megafauna tortoises (?Meiolania damelipi) on tropical islands during the late Holocene over a 281,000 km2 region of the southwest Pacific spanning from the Vanuatu archipelago to Viti Levu in Fiji. Zooarchaeological analyses have identified seven early archaeological sites with the remains of this distinctive hor...

The importance of wild barley from Qinghai-Tibet Plateau in the origin and domestication of cultivated barley has long been underestimated. Population-based phylogenetic analyses were performed to study the origin and genetic diversity of Chinese domesticated barley, and address the possibility that the Tibetan region in China was an independent center of barley domestication. Wild barley (Hord...

Numerous studies have demonstrated that a complex distribution of water resources, regional development, and management mechanisms create significant challenges for transboundary river basins. We utilized diagnostic thinking to examine the issues 14 main watersheds in three regions (Northeast, Northwest, Southwest) China. Our four diagnosis points were quantity, quality, ecological stability hu...

Introduction: One of the most prominent features of Mars is the global south to north slope of ~0.036° [1] discovered by analysis of data from the Mars Orbiter Laser Altimeter (MOLA) aboard Mars Global Surveyor. In contrast, Isidis Planitia, the floor of Isidis basin, slopes southwest at an angle of ~0.02° [2]. It has been suggested [3] that deflection of the lithosphere under a load located in...

We present a Chandra study of the metal distribution in the X-ray bright compact group of galaxies HCG 62. We find that the diffuse X-ray emission is peaked at the core of the central galaxy NGC 4778, and is dominated by the contribution of the hot gas. The diffuse emission is roughly symmetric within ≃ 0.25, which is straddled by double-sided X-ray cavities aligned in the northeast-southwest d...

Doppler wind lidar measurements were used for the first time in Romania to analyse and turbulence statistics a peri-urban site located at Măgurele, southwest of Bucharest. Vertical scanning between December 2019 November 2021 processed using an existing toolbox. The over two-year period performed on seasonal diurnal cycle bases. analyses showed horizontal speed, with lower values during daytime...
