We relate the canonical basis of the Fock space representation of the quantum affine algebra Uq(ĝln), as defined by Leclerc and Thibon [LT], to the canonical basis of its restriction to Uq(sln), regarded as a based module in the sense of Lusztig. More generally we consider the restriction to any Levi subalgebra. We deduce results on decomposition numbers and branching coefficients of Schur alge...

OBJECTIVE To assess reliability and validity of the objectively-structured clinical examination (OSCE) applied in postgraduate certification processes by the Mexican Board of Rheumatology. METHOD Thirty-two (2013) and 38 (2014) Rheumatology trainees (RTs) underwent an OSCE consisting of 12 and 15 stations respectively, scored according to a validated check-list, as well as 300-multiple-choice...

The three likelihood-based tests, namely, likelihood ratio test, Rao score test, and Wald test and two more asymptotic tests which use Srivastava’s estimator of intraclass correlation coefficient are considered to test the null hypothesis of equality of intraclass correlation coefficients when the families have unequal number of children. Methods are illustrated on Galton’s data set. Using simu...

BACKGROUND AND OBJECTIVE The STarT Back Tool uses prognostic indicators to classify patients with low back pain into three risk groups to guide early secondary prevention in primary care. The present study aimed to evaluate the psychometric properties of the Japanese version of the tool (STarT-J). METHODS An online survey was conducted among Japanese patients with low back pain aged 20-64 yea...

OBJECTIVE Attention-deficit/hyperactivity disorder (ADHD) is often associated with reduced IQ and high levels of externalizing behavior (EB). This study tested if DRD4 7-repeat allele and DAT1 10-repeat allele homozygosity interact in modulating correlations between IQ and EB in affected boys. METHODS Boys (n=130) between 6 and 12 years of age diagnosed with ADHD were included in the study. I...

BACKGROUND For real-time assessment of the probability of survival (Ps) of blunt trauma victims at emergency centers, this study aimed to establish regression models for estimating Ps using simplified coefficients. METHODS The data of 10,210 blunt trauma patients not missing both the binary outcome data about survival and the data necessary for Ps calculation by The Trauma and Injury Severity...

We develop an efficient general-purpose blind/no-reference image quality assessment (IQA) algorithm using a natural scene statistics (NSS) model of discrete cosine transform (DCT) coefficients. The algorithm is computationally appealing, given the availability of platforms optimized for DCT computation. The approach relies on a simple Bayesian inference model to predict image quality scores giv...

OBJECTIVE To identify the best anthropometric index that predicts cardiometabolic risk factors.Design and settingCross-sectional study in Turkey, in 2003. SUBJECTS Turkish men and women aged 18 years and over (n 1692) were examined. Body weight, height, waist and hip circumferences, blood pressure, total cholesterol, HDL cholesterol, TAG, glucose and insulin were measured. Metabolic syndrome ...

We construct an indicator variable (HighScore) to aggregate and summarize four recall characteristics that we expect to be associated with higher overall recall costs, including greater loss of reputation and future sales as well as higher expected litigation costs.1 We employ the dichotomous variable, HighScore, because it is easy to interpret and because the relation between the individual re...

This paper presents the single channel speech enhancement system using subband Kalman filtering by estimating optimal Autoregressive (AR) coefficients and variance for speech and noise, using Weighted Linear Prediction (WLP) and Noise Weighting Function (NWF). The system is applied for normal and Oesophageal speech signals. The method is evaluated by Perceptual Evaluation of Speech Quality (PES...
