Consider estimating the mean vector from data Nn( ; I) with lq norm loss, q 1, when is known to lie in an n-dimensional lp ball, p 2 (0;1). For large n, the ratio of minimax linear risk to minimax risk can be arbitrarily large if p < q. Obvious exceptions aside, the limiting ratio equals 1 only if p = q = 2. Our arguments are mostly indirect, involving a reduction to a univariate Bayes minimax ...

In common with many other specialities in medicine urology continues not only to evolve but to do so at an increasingly rapid pace. Diseases of the urinary tract are an extremely common cause of morbidity and in some respects are likely to become more so. With the rising proportion of the population represented by the elderly, manifestations of urological conditions in this age group is already...

In this work, we study the volume ratio of the projective tensor products `p ⊗π `q ⊗π `r with 1 ≤ p ≤ q ≤ r ≤ ∞. We obtain asymptotic formulas that are sharp in almost all cases. As a consequence of our estimates, these spaces allow for a nearly Euclidean decomposition of Kašin type whenever 1 ≤ p ≤ q ≤ r ≤ 2 or 1 ≤ p ≤ 2 ≤ r ≤ ∞ and q = 2. Also, from the Bourgain-Milman bound on the volume rat...

We complete the next-to-next-to-leading-order QCD calculation of the branching ratio for B̄ → Xsll including recent results for the three-loop anomalous dimension matrix and two-loop matrix elements. These new contributions modify the branching ratio in the low-q region, BRll, by about +2% and −2%, respectively. We furthermore discuss the appropriate normalization of the electromagnetic coupling...

This research work presents the study on fracture behavior of Al6061 with graphite particulate composite produced by the stir casting technique. The materials selected for the proposed work is Al6061 and graphite particles. Compact tension (CT) specimens were utilized to determine fracture toughness for different thickness of composite. In the present work, optimizing the parameters of the comp...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

BACKGROUND The acute coronary syndrome diagnosis includes different classifications of myocardial infarction, which have been shown to differ in their pathology, as well as their early and late prognosis. These differences may relate to the underlying extent of infarction and/or residual myocardial ischemia. The study aim was to compare scar and ischemia mass between acute non-ST elevation myoc...

Bicelles are model membranes generally made of long-chain dimyristoylphosphatidylcholine (DMPC) and short-chain dihexanoyl-PC (DHPC). They are extensively used in the study of membrane interactions and structure determination of membrane-associated peptides, since their composition and morphology mimic the widespread PC-rich natural eukaryotic membranes. At low DMPC/DHPC (q) molar ratios, fast-...

Background and Aims: Q fever is a public health concern in many countries especially in recent years. There are a few studies in Iran. This study aimed to determine the seropositivity for Q fever among veterinary staff in southern Khorasan, Iran. Methods: 92 serum samples were obtained from all veterinary employees and tested using an indirect enzyme-linked immunosorbent assay (ELISA). The data...
