A length k Newman polynomial is any polynomial of the form za1 + · · ·+zak (where a1 < · · · < ak). Some Newman polynomials are reducible over the rationals, and some are not. Some Newman polynomials have roots on the unit circle, and some do not. Defining, in a natural way, what we mean by the “proportion” of length k Newman polynomials with a given property, we prove that • 1/4 of length 3 Ne...

background: we presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (cabg) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. therefore, we examined whether the surgeon himself has an impact on the intensive care unit (icu) stay of isolated cabg patients. methods: we prospectively studied a tota...

-In storm waterways and at dam outlets, high-velocity supercritical flows are characterized by substantial air bubble entrainment. The entrainment of fine air bubbles and the strong turbulent mixing contribute both to the air-water transfer of volatile gases (e.g. oxygen, nitrogen, VOC). The paper describes new experimental data obtained in a 25 m long channel with a 4 ° slope. The analysis of ...

conclusions the patient cost increased as the length of stay increased due to the policy of bundle pricing. results the female/male ratio was 2.55. the mean age of the 71 poisoned patients was 28.92 ± 11.51 years. most of the poisoning agents were pharmaceuticals (68 cases). among the pharmaceuticals, antidepressants were involved most often, followed by analgesics. there was no statistically s...

INTRODUCTION Documentation and billing for laceration repair involves a description of wound length. We designed this study to test the hypothesis that emergency department (ED) personnel can accurately estimate wound lengths without the aid of a measuring device. METHODS This was a single-center prospective observational study performed in an academic ED. Seven wounds of varying lengths were...

PURPOSE To compare marginal and internal gaps of zirconia substructure of single crowns with those of three-unit fixed dental prostheses. MATERIALS AND METHODS Standardized Co-Cr alloy simulated second premolar and second molar abutments were fabricated and subsequently duplicated into type-III dental stone for working casts. After that, all zirconia substructures were made using Lava™ system...

T his paper is to examine the mean reverting properties of inflation rates for Iran’s 25 provinces over the period from 1990:4 to 2017:7. To the end, we use various conventional univariate linear and non-linear unit root tests, as well as quantile unit root test by Koenker and Xiao (2004). Results of conventional unit root tests indicate that the null hypothesis of the unit root test...

A rectangular drawing of a planar graph G is in which vertices are mapped to grid points, edges horizontal and vertical straight-line segments, faces drawn as rectangles. Sometimes this latter constraint relaxed for the outer face. In paper, we study drawings have unit length. We show complexity dichotomy problem deciding existence unit-length drawing, depending on whether face must also be rec...
