background: two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (ungal) in detection of acute kidney injury (aki) in children have remained unanswered; first, which cut-off point of ungal has the highest value in detection of aki; and second when is the best time for measuring this biomarker in a patient? accordingly, the present study aimed to conduct a syst...

introduction: group a beta-hemolytic streptococcus (gabhs) can induce pandas (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). gabhs is the most important and common bacterial cause of acute pharyngitis in iranian children. we studied the role of gabhs (anti-streptococcal antibodies) in suspected cases of pandas in a cross sectional studies. methods: acr...

This study aimed to find cut-off scores for the Montgomery-Asberg rating scale (MADRS) and the Beck depression inventory (BDI) that can relate to specific clinical diagnoses of depression in Parkinson s disease (PD). Mild and moderate PD patients (n=46) were evaluated for depression according to the DSM IV criteria. All patients were assessed with the MADRS and the BDI. A "receiver operating ch...

Background: Iron deficiency (ID) is the most common micronutrient deficiency in the world. If left untreated, ID will lead to iron deficiency anemia (IDA) and other irreversible consequences. The American Academy of Pediatrics recommended reticulocyte hemoglobin content (Ret-He) as an alternative laboratory examination to screen and detect ID. We aimed to compare Ret-He with other laboratory pa...

CIRCUMVENTINGTHE CUT-OFF FOR ENRICHMENTANALYSIS Abstract Three tools for threshold-free enrichment analysis of microarray data are introduced: GSEA (gene set enrichment analysis), ermineJ and DRIM (discovering rank imbalanced motifs).GSEA offers an interface to a specific algorithm and a well-defined pipeline for the identifying enrichment in diverse gene sets and the creation of signature prof...

We clarify the relationship between black hole entropy and the number of degrees of freedom in the dual QFT with a cutoff. We show that simple gravity arguments predict the correct cutoff procedure.

Verifying that a parameterized system satisfies certain desired properties amounts to verifying an infinite family of the system instances. This problem is undecidable in general, and as such a number of sound and incomplete techniques have been proposed to address it. Existing techniques typically focus on parameterized systems with a single parameter, (i.e., on systems where the number of pro...

If L is the combinatorial Laplacian of a graph, exp(−L t) converges to a matrix with identical coefficients. The speed of convergence is measured by the maximal entropy distance. When the graph is the sum of a large number of components, a cut-off phenomenon may occur: before some instant the distance to equilibrium tends to infinity; after that instant it tends to 0. A sufficient condition for...

ASTRONOMY AND ASTROPHYSICS Cutoff radii of galactic disks A new statistical study on the truncation of galactic disks Abstract. We present the analysis of a CCD survey of 31 nearby (≤ 110 Mpc) edge-on spiral galaxies. The three-dimensional one-component best fit models provide their disk-scalelengths h and for the first time their disk cutoff radii R co. We confirm for this sample the existence...
