Background: A thermistor is a nonlinear sensor requiring precise calibration technique to achieve accurate temperature measurements. This paper attempts design employing artificial neural network (ANN) algorithms. The present work fulfills the following objectives: (i) cover 100% input range in linearity measurement; (ii) make measurement adaptiv...

With the rise in antibiotic resistance amongst pathogenic bacteria, the study of antibiotic activity and transport across cell membranes is gaining widespread importance. We present a novel, label-free microfluidic assay that quantifies the permeability coefficient of a broad spectrum fluoroquinolone antibiotic, norfloxacin, across lipid membranes using the UV autofluorescence of the drug. We u...

To observe the effects of insulin resistance on gonadal steroid hormone stimulation and the myometrial growth of female rats in order to elucidate the relationship between insulin resistance and the development of uterine leiomyomas. We divided 180 nonpregnant female Wistar rats into three groups as follows: group A, as the control group; group B, as the "model by exogenous sex hormone" group; ...

At room temperature, YBCO possesses a relatively high temperature coefficient of resistance, −3.5% K−1, and a high pyroelectric coefficient, up to 20 μC cm−2 K−1. In this work, we report on the cryogenic characterization of semiconducting Y–Ba–Cu–O thin films on substrates in response to 100 fs optical pulses at 810 nm and suspended thin film pixels in response to chopped broadband infrared rad...

The hierarchical structure of spider dragline silk is composed of two major constituents, the amorphous phase and crystalline units, and its mechanical response has been attributed to these prime constituents. Silk mechanics, however, might also be influenced by the resistance against sliding of these two phases relative to each other under load. We here used atomistic molecular dynamics (MD) s...

UNLABELLED Studying biomechanical properties of the fibrous tunic of the eye meets current clinical demands. Previous studies have proved bidirectional corneal applanation suitable for this purpose. The so called corneal elasticity coefficient is more informative in terms of corneal elastance than the two other parameters measured during bidirectional corneal applanation, namely, corneal resist...

Normal reference values for the resistance index, A/B ratio and pulsatility index of the umbilical artery obtained by Doppler ultrasonography are presented. The resistance index and A/B ratio values are very similar to those previously published, indicating no need to formulate normal values for different populations. The pulsatility index differed from other published values, probably reflecti...

OBJECTIVES To determine how important governmental, social, and economic factors are in driving antibiotic resistance compared to the factors usually considered the main driving factors-antibiotic usage and levels of economic development. DESIGN A retrospective multivariate analysis of the variation of antibiotic resistance in Europe in terms of human antibiotic usage, private health care exp...
