background: integrons are mobile genetic elements able to obtain the antibiotic resistance gene cassettes. the prevalence of integrons in the enterobacteriaceae family has been varied and played an important role in the development of the drug resistant bacteria. the present study aimed to investigate the contribution of class 2 and 3 integrons in drug resistant diarrheagenic escherichia coli s...

In a recent article [J. C. Brown, "Calculation of a Constant Q Spectral Transform," J. Acoust. Soc. Am. 89, 425-434 ( 1991 ) ], the calculation of a constant Q spectral transform that gives a constant pattern in the log frequency domain for sounds with harmonic frequency components has been described. This property has been utilized in calculating the cross-correlation function of spectra of so...

This paper proposes a class of parametric correlation models that apply a twolayer autoregressive-moving-average structure to the dynamics of correlation matrices. The proposed model contains the Dynamic Conditional Correlation model of Engle (2002) and the Varying Correlation model of Tse and Tsui (2002) as special cases and offers greater flexibility in a parsimonious way. Performance of the ...

OBJECTIVE The objective of this study was to investigate the differences in masticatory efficiency among patients with different Angle's classes of malocclusion and to assess the correlation between masticatory efficiency and the occlusal contact area. METHODS The mixing ability index (MAI) was calculated for measuring masticatory efficiency of 61 adult patients according to Angle's classific...

Objective: Chloride is the major plasma anion. There are several methods available for the determination of serum chloride levels. Unfortunately these methods are sometimes not available in the urgent setting where values are needed. Here we describe...
