widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/l in effluent to µg/l concentrations in surface water. in a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the tennessee river, usa and its tributaries. in order to address the need for risk assessment of environmentally relevant pharmaceutical mixtures, da...

objective: ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...

background: birth weight and gestational age are two important variables in obstetric research. the primary measure of gestational age is based on a mother's recall of her last menstrual period. this recall may cause random or systematic errors. therefore, the objective of this study is to utilize bayesian mixture model in order to identify implausible gestational age.   methods: in this cross-...

abstract statement of problem: the ph of the human abscess has been measured as low as 5.0. this low ph could potentially inhibit setting reactions, affect adhesion, or increase the solubility of root end filling materials hence affect the compressive strength. moreover, root end filling materials might expose or even mix with lidocaine hcl during periapical surgery. objectives: the aim of this...

it has been reported that several members of convolvulaceae family such as convolvulus arvensis possess cytotoxic activity on some tumor cell lines. proteoglycan mixture, the water extract of c. arvensis with high molecular weight, has potent anti-angiogenesis and stimulating effects. in this study, arial parts of c. arvensis were collected and identified, and the cytotoxic effects of chlorofor...

This paper presents an output combination approach for noiserobust speech recognition. The aim of this work is to improve recognition performance for adverse conditions which contain both stationary and non-stationary noise. In the proposed method, both discrete-mixture HMMs (DMHMMs) and continuous-mixture HMMs (CMHMMs) are used as acoustic models. In the DMHMM, subvector quantization is used i...

This article address a novel emotion recognition system based on the Truncated Gaussian mixture model .The proposed system has been experimented over an gender independent emotion recognition database In the recent past, many models have been listed in the literature based on the emotion recognition, but these papers are more focused towards the speech, ignoring the emotion of the speaker at th...

Correct functioning of cyber-physical systems is of critical importance. This is more so in the case of safety critical systems such as in medical, automotive and many other applications. Since verification of correctness, in general, is infeasible and testing is not exhaustive, it is of critical importance to monitor such system during their operation and detect erroneous behaviors to be acted...

The Cluster-Weighted Modeling (CWM) is emerging as a versatile tool for modeling dynamical systems. It is a mixture density estimator around local models. To be specific, the input regions together with output regions are treated to be Gaussian serving as local models. These models are linked by a linear or non-linear function involving the mixture of densities of local models. The present work...

From the philosophical viewpoint, two interpretations of the quantum measurement process are possible: According to the first interpretation, when we measure an observable, the measured system moves into one of the eigenstates of this observable (“the wave function collapses”); in other words, the Universe “branches” by itself, due to the very measurement procedure, even if we do not use the re...
