Calibration in atomic-absorption spectrometry is achieved by means of a concentrationgradient chamber using a single concentrated standard solution. Calibration is rapid and extends over the entire working concentration range of the analyte, irrespective of the shape of the conventionally obtained calibration curve. No curve-fitting approximations are involved. With well-designed apparatus, dev...

The aim of this paper is to review some of standard fact on Miura curves. We give some easy theorem in number theory to define Miura curves, then we present a new implementation of Arita algorithm for Miura curves. Keywords—Miura curve, discrete logarithm problem, algebraic curve cryptography, Jacobian group.

This application note describes the use and implementation of elliptic curve digital signature algorithm (ECDSA) on the MAXQ1103 microcontroller's modular arithmetic accelerator (MAA) module. Performance figures are given for a standard 160-bit curve specified in Standards for Efficient Cryptography published by Certicom®.

An account is given of asymptomatic diabetes mellitus. To determine the incidence in 200 patients with senile cataract 3 tests are described, namely, a modified standard glucose tolerance test, a provocative steroid glucose tolerance test, and a standard glucose tolerance test. Known diabetics and patients with a fasting blood glucose in excess of 5.5 mmol/l or glycosuria were excluded. Eighty-...

Fluorescent monitoring of DNA amplification is the basis of real-time PCR, from which target DNA concentration can be determined from the fractional cycle at which a threshold amount of amplicon DNA is produced. Absolute quantification can be achieved using a standard curve constructed by amplifying known amounts of target DNA. In this study, the mathematics of quantitative PCR are examined in ...

We propose a new Elliptic curve at a security level signi cantly greater than the standard 128 bits, that lls a gap in current proposals while bucking the expected security vs cost curve by exploiting the new trick recently described by Granger and Scott. This essentially reduces the cost of eld multiplication to that of a eld squaring.

Standard open economy models predict that openness to trade should exert a positive e¤ect on the slope of the output-in‡ation tradeo¤, or Phillips curve, but such a proposition …nds very little support in the existing empirical literature. We propose a new test of this hypothesis based on new measures of the slope of the Phillips curve and more general cross-country regression models. The resul...

We introduce equity forward variance term-structure models and derive the respective HJM-type arbitrage conditions. We then discuss finitedimensional Markovian representations of the infinite-dimensional fixed time-to-maturity forward variance swap curve and analyse examples of such variance curve functionals. The results are then applied to show that the speed of mean-reversion in standard sto...

varieties of st. john’s wort (hypericum perforatum l.) native to iran possess the largest percentage of hypercin in their leaves and flowers. isotherm curves show the relationship between the relative humidity and moisture content of the plant at a constant temperature. it is essential to understand the isotherms curves for successful storage and drying of the plant. this study used adsorption ...

following a magnetic survey in saghande yazd region, the existance of a relatively important dike shape anomaly was detected. in the present study, this anomaly has been interpreted by the werner deconvolution method and parker standard curves. the location and depth of the uper surface of magnetic dike has been calculated by the werner method using a series of profiles perpendicular to the str...
