We present the clustering of DEEP2 galaxies at 0.7 < z < 1.4 around quasars identified using both the SDSS and DEEP2 surveys. We measure the two-point cross-correlation of a sample of 36 opticallyselected, spectroscopically-identified quasars from the SDSS and 16 more found in the DEEP2 survey with the full DEEP2 galaxy sample over scales 0.1 < rp < 10 h −1 Mpc. The clustering amplitude is foun...
We determine the three-dimensional shear wave velocity structure of the crust and upper mantle in China using Green’s functions obtained from seismic ambient noise cross-correlation. The data we use are from the China National Seismic Network, global and regional networks and PASSCAL stations in the region. We first acquire cross-correlation seismograms between all possible station pairs. We t...
OBJECTIVE To transculturally adapt the Spanish version of Pregnancy Physical Activity Questionnaire (PPAQ) analyzing its psychometric properties. METHODS The PPAQ was transculturally adapted into Spanish. Test-retest reliability was evaluated in a subsample of 109 pregnant women. The validity was evaluated in a sample of 208 pregnant women who answered the questionnaire and wore the multi-sen...
Objectives: To determine the relationship between script concordance test scores obtained at the end of clerkship rotation in ob-gyn and global performance measures for the entire curriculum as expressed by a preclinical and clerkship score in the Dean’s Letter. The relationship also considered two other existing instruments. Methods: A cross-sectional study was carried out on a convenience sam...
Background and purpose: Breast cancer is the most common type of cancer in women and the second cause of cancer death in Iran. Widespread use of mammography and sonography could increase survival in patients with early detection. Sensitivity and specificity of mammography and sonography are different in various sources. This study aimed at assessing the concordance of mammography-sonography rep...
About 28% of genes appear to have an expression pattern that follows a mixture distribution. We use first- and second-order partial correlation coefficients to identify trios and quartets of non-sex-linked genes that are highly associated and that are also mixtures. We identified 18 trio and 35 quartet mixtures and evaluated their mixture distribution concordance. Concordance was defined as the...
OBJECTIVES To assess the accuracy and correlation between Colposcopically Directed Biopsy (CDB) and Large Loop Excision of the Transformation Zone (LLETZ) and the influence of age. MATERIAL AND METHOD A comparative analysis was conducted from the 352 women referred to Rajavithi Hospital from January 1998 to December 2003, to compare between CDB and LLETZ. Correlation was assessed by the perce...
Interprofessional collaboration between doctors and nurses is based on team mental models, in particular for each professional's roles. Our objective was to identify factors influencing concordance on the expectations of doctors' and nurses' roles and responsibilities in an Internal Medicine ward. Using a dataset of 196 doctor-nurse pairs (14x14 = 196), we analyzed choices and prioritized manag...
OBJECTIVE To determine the validity of adult body weights and heights recorded in electronic medical records (EMRs) in the course of routine medical care. BACKGROUND EMRs allow the potential use of data collected in the course of routine medical care for a variety of research applications in many fields including epidemiology and comparative effectiveness studies. However, researchers familia...
