background in order to detect nephropathy, measurement of total (24 hrs) urinary albumin or albumin/creatinin ratio in random urine samples is being recommended. but methods of albumin measurement are not available in all laboratories and also cost about 6 times more than that of urinary total protein measurement. objectives this study was performed to determine appropriate cut off point in 24 ...

In this article, we would like to show that there is no cut point of any point in a plane, but there exists the cut locus of a point in a flat torus. By the results, we would like to determine the structure of cut locus of a flat torus. Keywords—Cut locus, flat torus, geodesics.

Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...

conclusions herein we have described the stata package “adpredsurv” for calculation of the nam-d’agostino x2 goodness of fit test as well as cut point-free and cut point-based nri, relative and absolute idi, and survival-based regression analyses. we hope this work encourages the use of novel methods in examining predictive capacity of the emerging plethora of novel biomarkers. background a fun...

background: the homeostasis model assessment of insulin resistance (homa-ir) is a useful model for application at large epidemiologic studies. the aim of this study was to determine the homa cut off values to identify insulin resistance (ir) and metabolic syndrome (ms) in qazvin, central iran. methods: overall, 480 men and 502 women aged 20-72 yr attended in this cross sectional study from sept...

this study planned for finding the agreement dxa and quantitative ultrasound (qus) of phalanx in osteoporosis diagnosis and cut off point of qus for osteoporosis diagnosis in postmenopausal women. in 180 postmenopausal women, bmd of axial regions with dxa (dpx-md, ge, lunar, usa) and phalanx with qus (dbm-sonic 1200) measured. agreement of methods and cut off for qus in defining osteoporosis ob...
