The paper investigates experimentally the flow past a flat-back, taller than wide Ahmed body having rectangular base aspect ratio $H/W=1.11$ in context of ground vehicle aerodynamics. Parametric studies at Reynolds number $2.1\times 10^5$ explore sensitivity aerodynamic force and pressure distribution with respect to varying conditions defined from variable clearance $C$ (taken mid-distance fro...

Caudolateral curvilinear osteophytes (CCOs) are considered to be an important finding for the early detection of canine hip dysplasia. The objective of this study was to determine the association between the radiographic and anatomic appearance of CCOs, and to determine whether CCOs are indicative of osteoarthritis. One hundred canine femurs were used to determine the topographical location of ...

A new computer program, HYPER, has been developed for automated analysis of protein dihedral angle values and C beta H2 stereospecific assignments from NMR data. HYPER uses a hierarchical grid-search algorithm to determine allowed values of phi, psi, and chi 1 dihedral angles and C beta H2 stereospecific assignments based on a set of NMR-derived distance and/or scalar-coupling constraints. Dihe...

The hydrophobic effect is the main thermodynamic driving force in the folding of water-soluble proteins. Exclusion of nonpolar moieties from aqueous solvent results in the formation of a hydrophobic core in a protein, which has been generally considered essential for specifying and stabilizing the folded structures of proteins. Outer surface protein A (OspA) from Borrelia burgdorferi contains a...

purpose: to evaluate visual outcomes and intraocular pressure (iop) after single-site phacotrabeculectomy with mitomycin c in patients with senile cataract and primary open angle glaucoma (poag), pseudoexfoliative glaucoma (pxg), or chronic angle closure glaucoma (cacg). methods: in this retrospective study, patients older than 50 years who had significant cataracts (bcva £ 20/60) and uncontrol...

Taking the recently reported non-zero rotation angle of cosmic microwave background (CMB) linear polarization $\beta=0.35\pm0.14{\rm\, deg}$ as hint for a pseudo Nambu-Goldstone boson quintessence dark energy (DE), we study electroweak (EW) axion DE model where mass is generated by EW instantons. We find that observed value $\beta$ implies non-trivial $U(1)$ electromagnetic anomaly coefficient ...

Motivated by problems of hyperbolic stochastic geometry we introduce and study the class beta-star polytopes. A polytope is defined as convex hull an inhomogeneous Poisson processes on complement unit ball in Rd with density proportional to (‖x‖2−1)−β, where ‖x‖>1 β>d/2. Explicit formulas for various geometric combinatorial functionals associated polytopes are provided, including expected numbe...

We report the case of a 75-year-old woman who developed an acute bilateral angle-closure associated with choroidal effusion a day after an uneventful cataract surgery. The same patient had undergone a similarly uneventful cataract surgery two weeks before, under the same protocol, with no postoperative complication in the other eye. Medical treatment, including the use of oral sulfamide-related...
