background a strong association between obesity and non-alcoholic fatty liver disease (nafld) has been reported. objectives this study was conducted to evaluate if new obesity indices, including a body shape index (absi) and body roundness index (bri), have stronger associations with nafld than waist-to-hip ratio (whr) and waist-to-height ratio (whtr). methods in this cross-sectional study, we ...

background: to determine a cut-off point of tpsa and psad to prevent unnecessary invasive cancer-diagnosing tests in the community. methods: this study was performed on 688 consecutive patients referred to our center due to prostatism, suspicious lesions on digital rectal examination and/or elevated serum psa levels. all patients underwent transrectal ultrasound guided biopsies and obtained psa...

In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

During the last decade various techniques have been proposed to extract the ground surface from airborne LIDAR data. The basic problem is the separation of terrain points from off-terrain points which are both recorded by the LIDAR sensor. In particular geometry driven filtering, detection or classification procedures are developed which use knowledge to find points, e.g. on buildings or vegeta...

background unlike developed countries, data from the developing world regarding motor developmental disorders is scarce. objectives in the present study, we used the infant neurological international battery (infanib) test to determine the prevalence of motor impairment in 4-18 month-old infants in alborz province, iran, in 2010. patients and methods this study was a descriptive-analytic study ...

BACKGROUND Body mass index (BMI) and waist circumference (WC) are used to define cardiovascular and type 2 diabetes risk. We aimed to derive appropriate BMI and WC obesity cut-off points in a migrant South Asian population. METHODS 4688 White Europeans and 1333 South Asians resident in the UK aged 40-75 years inclusive were screened for type 2 diabetes. Principal components analysis was used ...

Encoding/decoding off-axis points with discrete orbital angular momentum (OAM) modes is investigated. On-axis Laguerre-Gaussian (LG) beams are expanded into off-axis OAM spectra, with which off-axis points are encoded. The influence of the mode and the displacement of the LG beam on the spread of the OAM spectrum is analysed. The results show that not only the conventional on-axis point, but al...
