The Tile Calorimeter (TileCal) is the central section of the hadronic calorimeter of ATLAS experiment of the Large Hadron Collider (LHC) and has about 10,000 eletronic channels. An Optimal Filter (OF) has been used to estimate the energy sampled by the calorimeter and applies a Quality Factor (QF) for signal acceptance. An approach using Matched Filter (MF) has also been pursued. In order to co...

Thermal atomic layer-deposited (ALD) aluminum oxide (Al2O3) acquires high negative fixed charge density (Qf) and sufficiently low interface trap density after annealing, which enables excellent surface passivation for crystalline silicon. Qf can be controlled by varying the annealing temperatures. In this study, the effect of the annealing temperature of thermal ALD Al2O3 films on p-type Czochr...

OBJECTIVE To compare equations for predicting peak quadriceps femoris (QF) muscle force; to determine the agreement among the equations in identifying QF muscle weakness in COPD patients; and to assess the differences in characteristics among the groups of patients classified as having or not having QF muscle weakness by each equation. METHODS Fifty-six COPD patients underwent assessment of p...

INTRODUCTION QF PCR has recently entered diagnostic practice as a possible way to bypass culturing of the fetal cells, as well as to provide a rapid response following amniocentesis. MATERIAL AND METHODS The effective value of the QF PCR remains a much debated issue, positions ranging from that it makes classic kayotyping obsolete except in special occasions, to that it is no more than a guid...

First we discuss briefly our former characterization theorem for positive interpolation quadrature formulas (abbreviated qf), provide an equivalent characterization in terms of Jacobi matrices, and give links and applications to other qf, in particular to Gauss-Kronrod quadratures and recent rediscoveries. Then for any polynomial tn which generates a positive qf, a weight function (depending on...

Rate control plays an essential role in video coding and transmission to provide the best video quality at the receiver’s end given the constraint of certain network conditions. In 17 this paper, a rate control algorithm using the Quality Factor (QF ) optimization method is proposed for the wavelet-based video codec and implemented on an open source Dirac 19 video encoder. A mathematical model ...

OBJECTIVE To validate quantitative fluorescent polymerase chain reaction (QF-PCR) via chorionic villus sampling (CVS) for the diagnosis of fetal aneuploidies. METHODS We retrospectively reviewed the medical records of consecutive pregnant women who had undergone CVS at Cheil General Hospital between December 2009 and June 2014. Only cases with reported QF-PCR before long-term culture (LTC) fo...
