BACKGROUND Porcine reproductive and respiratory syndrome virus (PRRSV) is recognized worldwide as an important and economically devastating pathogen in pig production. Although PRRSV is widespread in domestic swine, there is a lack of information regarding PRRSV infection in European wild boars (Sus scrofa). Currently available information does not provide conclusive evidence that wild boars ar...

We developed an assay for the detection and quantitation of norovirus with the LightCycler SYBR Green-based real-time reverse transcription-PCR (real-time LC RT-PCR) and previously published primers in the capsid and the polymerase gene. One hundred thirty-two stool specimens from the Provincial Laboratory for Public Health (Microbiology), Alberta, Canada, and the Centers for Disease Control an...

Despite high-level evidence, the benefit of postmastectomy RT in these patients in recent years has not been fully elucidated. We investigated postmastectomy radiotherapy (RT) use and evaluated clinicopathologic and treatment factors influencing RT use in Korean women with pT1-2N1 breast cancer.We identified women diagnosed with pT1-2N1 breast cancer between 1994 and 2009 using the Korean Breas...

this study was undertaken to investigate the effect of long-term reduced tillage on grain yield, grain quality, and weed infestation of spring wheat. the experimental variables were three tillage systems: (a) conventional tillage (ct): shallow ploughing (10-12 cm) and harrowing after harvest of the previous crop, ploughing (25-30 cm) in the autumn; (b) reduced tillage (rt): only a cultivator (1...

Under a suitable sparsity condition on the exponents Λ = {λk = τk+ iσk}, it is shown that the individual terms cT = {ck ek} can be obtained from observation of the L function f(t) = ∑ ck e iλkt through the ‘window’ t ∈ [0, δ] — with an ` estimate (uniform for such Λ) asymptotically as T, δ → 0. Some applications are given to control theory for partial differential equations.

Let Ea : y 2 + xy = x + ax + 1/F2m be a Koblitz curve. The window τ -adic nonadjacent-form (window τNAF) is currently the standard representation system to perform scalar multiplications on Ea by utilizing the Frobenius map τ . Pre-computation is an important part for the window τNAF. In this paper, we first introduce μτ̄ -operations in lambda coordinates (μ = (−1)1−a and τ̄ is the complex conjug...

Introduction: Breast conserving surgery followed by adjuvant radiotherapy (RT) of the whole breast is accepted as the treatment of choice in early stage breast cancer. Due to breast irregularities, it is difficult to access homogenous dose distribution with conventional techniques. Currently, it is possible to use varied breast irradiation techniques, such as field- in-field (F...

BACKGROUND Parental height data are essential in the assessment of linear growth in children. A number of studies have documented inaccuracy in self-reported adult height. AIMS To determine whether there is a tendency for men to overestimate and women to underestimate their height. METHODS Heights of parents of children attending outpatient clinics were measured (MHt) and compared with repo...
