We introduce a property of forcing notions, called the anti-R1,א1 , which comes from Aronszajn trees. This property canonically defines a new chain condition stronger than the countable chain condition, which is called the property R1,א1 . In this paper, we investigate the property R1,א1 . For example, we show that a forcing notion with the property R1,א1 does not add random reals. We prove tha...
In this paper, we prove that for a bounded domain Ω in a rank-1 symmetric space, the first non-zero Neumann eigenvalue μ1(Ω) ≤ μ1(B(r1)) where B(r1) denotes the geodesic ball of radius r1 such that vol(Ω) = vol(B(r1)) and equality holds iff Ω = B(r1). This result generalises the works of Szego, Weinberger and Ashbaugh-Benguria for bounded domains in the spaces of constant curvature.
The self-assembly in solution and adsorption at the air-water interface, measured by small-angle neutron scattering, SANS, and neutron reflectivity, NR, of the monorhamnose and dirhamnose rhamnolipids (R1, R2) and their mixtures, are discussed. The production of the deuterium-labeled rhamnolipids (required for the NR studies) from a Pseudomonas aeruginosa culture and their separation into the p...
Notoginsenoside R1 (R1) is the main bioactive component in Panax notoginseng, an old herb medicine widely used in Asian countries in the treatment of microcirculatory diseases. However, little is known about the effect of R1 on inflammatory bowel disease (IBD). The present study demonstrated that R1 alleviated the severity of dextran sulfate sodium–induced colitis in mice by decreasing the acti...
Mobile advertising was early identified as an application for mobile data. Up to today the involved players, the mobile telecommunications companies and the advertising industry are looking for innovative concepts and new revenue streams. It therefore is not obvious why current mobile advertising and marketing approaches are lacking the predicted success. Taking the German market as object for ...

POLYMORPHIC PIPELINE ARRAY: A FLEXIBLE MULTICORE ACCELERATOR FOR MOBILE MULTIMEDIA APPLICATIONS
The hydraulic resistance of the leaf (R1) is a major bottleneck in the whole plant water transport pathway and may thus be linked with the enormous variation in leaf structure and function among tropical rain forest trees. A previous study found that R1 varied by an order of magnitude across 10 tree species of Panamanian tropical lowland rain forest. Here, correlations were tested between R1 an...
OBJECTIVES To examine whether the maternal serum concentration of the soluble receptor-1 of tumor necrosis factor-alpha (TNF-R1) at 11-13 weeks of gestation in pregnancies that subsequently develop pre-eclampsia is different from that in women without this complication. METHODS The concentration of TNF-R1 at 11 + 0 to 13 + 6 weeks was measured in samples from 128 cases that subsequently devel...
