An enzymatic assay for plasma homocysteine was developed that uses a crude lysate of E. coli containing the recombinant enzyme, methionine γ-lyase. The assay uses a commercially available fluorophore and 96-well microtiter plates; it can be performed manually or with the TECAN automated analyzer. The CVs for within-run and between-run precision are <10%. Close correlation (r >0.9) was obtained ...

Recycled concrete from construction waste used as road material is a current sustainable approach. To provide feasible suggestions for civil engineers to prepare recycled with high flexural strength (FS) the pavement, present study proposed three hybrid machine learning models by combining support vector (SVM), decision tree (DT) and multiple linear regression (MLR) firefly algorithm (FA) compu...

Az utóbbi 5-10 évben sorra épülnek világszerte az egyre magasabb fa magasházak, „tömegfa” (mass timber) tartószerkezetű épületek, és Franciaország sem akar ebből kimaradni. Ez a szerethető kisebb épület egy párizsi foghíjtelekre épült, kis karbonlábnyommal.

We present a new model-based monaural speech separation technique for separating two speech signals from a single recording of their mixture. This work is an attempt to solve a fundamental limitation in current model-based monaural speech separation techniques in which it is assumed that the data used in the training and test phases of the separation model have the same energy level. To overcom...

14 NOTICES OF THE AMS VOLUME 50, NUMBER 1 I mage processing, traditionally an engineering field, has attracted the attention of many mathematicians during the past two decades. From the point of view of vision and cognitive science, image processing is a basic tool used to reconstruct the relative order, geometry, topology, patterns, and dynamics of the three-dimensional (3-D) world from two-di...

Statistic classifiers operate on features that generally include both, useful and useless information. These two types of information are difficult to separate in feature domain. Recently, a new paradigm based on Factor Analysis (FA) proposed a model decomposition into useful and useless components. This method has successfully been applied to speaker recognition tasks. In this paper, we study ...
