tight junctions are required for the formation of tissue barriers and function as suppressors of signalling mechanisms that control gene expression and cell behaviour; however, little is known about the physiological and developmental importance of such signalling functions. here, we demonstrate that depletion of marve... | control of neural crest induction by marveld3-mediated attenuation of jnk signalling |
some carbon-rich wolf-rayet stars are permanent dust producers, as seen by their infrared excess. in famous targets like wr104, the dust is found in the form of a pinwheel nebula around the central source, providing an indirect evidence of binarity. wr104 has been studied in details with the keck, and more recently wit... | sharp images of wr104 |
soft clay formations are extensively located in many coastal areas around the world. the significant high compressibility and low shear strength of these formations impose challenging engineering problems. the deep cement/lime-mix-in-place method is one of the ground improvement techniques exhibiting successful use in ... | engineering properties of cement/lime-stabilized egyptian soft clay |
the al shomou silicilyte member (athel formation) in the south oman salt basin shares many of the characteristics of a light, tight-oil (lto) reservoir: it is a prolific source rock mature for light oil, it produces light oil from a very tight matrix and reservoir, and hydraulic fracking technology is required to produ... | diagenesis of a light, tight-oil chert reservoir at the ediacaran/cambrian boundary, sultanate of oman |
matisse (multi aperture mid-infrared spectroscopic experiment) is the spectro-interferometer for the vlti of the european southern observatory (eso), operating in the l-, m- and n- spectral bands, and combining up to four beams from the unit or the auxiliary telescopes (uts or ats). matisse will offer new breakthroughs... | matisse: performance in laboratory, results of aiv in paranal, and first results on sky |
the fluctuating climatic conditions of the saharo-arabian desert belt are increasingly important for both palaeoclimatic and palaeoanthropological debates. currently, saharo-arabia acts as a vast biogeographic barrier between the afrotropical and palaearctic realms. on orbital timescales, northward incursions of the af... | last interglacial saharo-arabian palaeoclimate variability and homo sapiens dispersal: insights from the speleothem record of southern arabia |
the oman drilling project (omandp) is a major, multidisciplinary scientific research program investigating processes preserved and occurring in the rocks of the samail ophiolite, oman; the largest and best subaerial exposure of ancient fast spread ocean crust and upper mantle the overarching goals of omandp are to unde... | introduction to the oman drilling project |
carbon dioxide mineralization via co2-fluid-rock reactions provides the most permanent solution for geologic co2 storage. basalts, onshore or offshore, have the potential to store million metric tons of co2 as (ca, mg, fe) carbonates [1, 2]. however, as of today it was unclear how fast co2 is converted to carbonate min... | carbfix i: rapid co2 mineralization in basalt for permanent carbon storage |
this atlas presents mid-infrared interferometric spectra of 82 low- and intermediate-mass young stellar objects (ysos). the data were taken from the archive of the mid-infrared interferometric instrument (midi) on the very large telescope interferometer. our sample contains 82 objects, of which 45 are t tauri stars, 11... | vizier online data catalog: midi atlas of low- and intermediate-mass ysos (varga+, 2018) |
synchronous dynamics of populations reduces metapopulation persistence. thus, determining sources of synchrony is important for understanding metapopulations and biodiversity patterns in response to environmental disturbance. previously, we found that the experimental extinction of two contiguous subpopulations of the ... | population extinction and metapopulation synchrony: a reassessment |
