We determine the p-rank of the incidence matrix of hyperplanes of PG(n, pe) and points of a nondegenerate quadric. This yields new bounds for ovoids and the size of caps in finite orthogonal spaces. In particular, we show the nonexistence of ovoids in O10(2e), O10(3e), O9(5e), O12(5e) and O12(7e). We also give slightly weaker bounds for more general finite classical polar spaces. Another applic...

Abstract. Coastal southeast South America is one of the classic locations where there are robust, spatially extensive records past high sea level. Sea-level proxies interpreted as last interglacial (Marine Isotope Stage 5e, MIS 5e) exist along length Uruguayan and Argentinian coast with exceptional preservation especially in Patagonia. Many coastal deposits correlated to 5e solely because they ...

The title compound, C(25)H(28)O(7), was prepared by the base-catalysed reaction of 3,4,5-trimethoxy-benzaldehyde with cyclo-penta-none. The mol-ecule has crystallographic twofold rotation symmetry and adopts an E-configuration about the central olefinic bonds. The two benzene rings and the central cyclo-penta-none ring are almost coplanar [dihedral angle = 4.7 (2)°].

Mutations of cilia-expressed proteins are associated with an attenuated shear-induced increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) in renal epithelial cell lines derived from murine models of autosomal recessive polycystic kidney disease (ARPKD). We hypothesized that human ARPKD cyst-lining renal epithelial cells also exhibited dysregulated mechanosensation. To test this, condit...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...

Adv. Mater. 2021, 33, 2005612 Mistakes in Figure 2a and 5e are corrected here. i) In 2a, the temperature should refer to 623 K, as is mentioned caption, instead of 723 which published image. ii) 5e, lower right inset, yellow atom represents Ge, rather than Sb quoted originally figure. The figures shown below.
