quantitative and model-based prediction of security in the architecture design stage facilitates early detection of design faults hence reducing modification costs in subsequent stages of software life cycle. however, an important question arises with respect to the accuracy of input parameters. in practice, security parameters can rarely be estimated accurately due to the lack of sufficient kn...

In this paper a study is accomplished on behavior in a mercury electrode, of the phytohormone abscisic acid and of the conditions of accumulation in a HMDE. A mechanism is proposed of reduction based on its electrochemical behavior and proving the product of the reduction through mass spectrometry of bulks. A method is proposed for the determination of Abscisic acid (ABA) with a quantification ...

We report on the determination of creatinine in human serum using a point-of-care device suitable for the use by untrained operators, the Medimate Multireader®. This device is based on electrophoretic separation and conductivity detection and its prefilled microfluidic chip has a single opening for sample introduction. The device was originally developed for the determination of lithium in bloo...

A simple and rapid quantification method was developed for determining nisoldipine in plasma. After a simple protein precipitation with a mixture of 10% of zinc sulfate and methanol, the analytes were chromatographed on a reversed-phase C(18) column, and detected by MS/MS. The assay precision was less than 10.7%, and the accuracy ranged from 86 to 112%. The limit of quantification was 0.1 ng/ml...

In this paper we demonstrate the only available scalable information bounds for quantities of interest of high dimensional probabilistic models. Scalability of inequalities allows us to (a) obtain uncertainty quantification bounds for quantities of interest in the large degree of freedom limit and/or at long time regimes; (b) assess the impact of large model perturbations as in nonlinear respon...

A multivariate quantitative data is often summarized into a general index as a weighted sum when each variate has a prescribed order. Although the sum of standardized scores is a sensible choice of index, it may have negative correlation with some of the variates. In this paper, a general index that has positive correlation with all the variates is constructed. The index is applied to study the...

A simple, rapid, and ultra sensitive dispersive solid phase extraction based on nano graphene oxide was developed for simultaneous measurement of trace amounts of metformin (MET) and linagliptin (LIN) in plasma samples by HPLC-UV-Vis. Affecting factors on the extraction of these drugs, including adsorbent weight, extraction time, organic solvent type, desorption situations, and composition of s...
