Let XR be the zero locus in RP n of one or two independently and Weyl distributed random real quadratic forms. Denoting by XC the complex part in CP n of XR and by b(XR) and b(XC) the sums of their Betti numbers, we prove that: (1) lim n→∞ Eb(XR) n = 1. In particular for one quadric hypersurface asymptotically Smith’s inequality b(XR) ≤ b(XC) is expected to be sharp. The methods we use combine ...

The atypical antipsychotic quetiapine fumarate is available both as an immediate release (IR) and as an extended release (XR) formulation allowing flexibility of dosing for individual patients. Approved uses of quetiapine XR include the treatment of schizophrenia (including maintenance therapy for prevention of relapse), the treatment of bipolar disorder (manic and depressive episodes), and the...

OBJECTIVE We investigated low dose digital tomosynthesis (DT) for the evaluation of the paranasal sinus (PNS), and compared its diagnostic accuracy with a PNS radiography series (XR). MATERIALS AND METHODS We enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo simulation software. Two radiologists perfo...

BACKGROUND The production of ethanol and other fuels and chemicals from lignocellulosic materials is dependent of efficient xylose conversion. Xylose fermentation capacity in yeasts is usually linked to xylose reductase (XR) accepting NADH as cofactor. The XR from Scheffersomyces stipitis, which is able to use NADH as cofactor but still prefers NADPH, has been used to generate recombinant xylos...

We consider codes defined over an affine algebra A = R[X1, . . . , Xr]/ 〈t1(X1), . . . , tr(Xr)〉, where ti(Xi) is a monic univariate polynomial over a finite commutative chain ring R. Namely, we study the A−submodules of A (l ∈ N). These codes generalize both the codes over finite quotients of polynomial rings and the multivariable codes over finite chain rings. Some codes over Frobenius local ...

In most RTP-based multicast applications, the RTP source sends interrelated data. Due to this interdependency, randomly joining RTP receivers usually cannot start consuming the multicast data right after they join the session. Thus, they often experience a random acquisition delay. An RTP receiver can use one or more different approaches to achieve rapid acquisition. Yet, due to various factors...

OBJECTIVE To compare 5mm slice computerized tomography (CT) and conventional x-ray (XR) in the detection of bone metastases in breast carcinoma patients. METHODS Ninety-eight female breast cancer patients treated in Ankara Oncology Hospital, Ankara, Turkey between September 1997 and March 2002 were assigned into 3 groups with respect to their Tc bone scan (Sc) results. Group 1 included patien...

For a general class of distributions some characterizations through the properties of conditional expectations of order statistics and progressively TypeII censored order statistics are given. Let X1 n X2 n Xn n be the order statistics of the sample X1 X2 Xn from a continuous distribution and XR 1 m n X R 2 m n X R m m n be the progressively Type-II censored order statistics with the progressiv...

A series of well-defined poly(oxy(11-phosphorylcholineundecylthiomethyl)ethylene-ran-oxy(n-dodecylthiomethyl)ethylene) (PECH-PCm: m = 0-100 mol% phosphorylcholine (PC)) polymers were used to prepare nanoscale thin films that were characterized by synchrotron X-ray reflectivity (XR) analysis. The quantitative XR analysis provided structural insights into the PECH-PCm thin films. The PECH-PC0 pol...

ABSTRACf Let us consider the linear model Y = XO + E in the usual matrix notation, where the errors are independent and identically distributed. Our main objective is to develop robust Wald-type tests for a large class of hypotheses on OJ by 'robust' we mean robustness in terms of size and power against long tailed error distributions. First, assume that the error distribution is symmetric abou...
