Convolutional RNN: an Enhanced Model for Extracting Features from Sequential Data [PDF]

open access: yes, 2016
Traditional convolutional layers extract features from patches of data by applying a non-linearity on an affine function of the input. We propose a model that enhances this feature extraction process for the case of sequential data, by feeding patches of

Bioavailability of heavy metals in the soil of Doustbaglu region (Meshginshahr) and determining toxic species by sequential extraction and Visual Minteq software [PDF]

open access: yesعلوم محیطی, 2022
Introduction: Oxidation of sulfide mineralized zones during the weathering processes is intensified by biological and chemical reactions and the resulting Acid Mine Drainage (AMD) causes the release and mobility of toxic and heavy metals from the parent ...

Fractionation of lead in soil by isotopic dilution and sequential extraction [PDF]

open access: yes, 2011
‘Reactivity’ or ‘lability’ of lead is difficult to measure using traditional methods. We investigated the use of isotopic dilution with 204Pb to determine metal reactivity in four soils historically contaminated with contrasting sources of Pb, including (

Extractable information capacity in sequential measurements metrology

open access: yesPhysical Review Research, 2023
The conventional formulation of quantum sensing is based on the assumption that the probe is reset to its initial state after each measurement. In a very distinct approach, one can also pursue a sequential measurement scheme in which time-consuming resetting is avoided.

Determinação de Cu, Fe, Mn, Zn e do teor de proteína total em amostras de trigo e soja após procedimento de extração sequencial

open access: yesQuímica Nova, 2012
A sequential extraction procedure was applied to wheat and soybean seed samples. The total protein content (determined by two distinct methods: Bradford and bicinchoninic acid-BCA) and distribution of Cu, Fe, Mn and Zn in each fraction was determined ...

Testing sequential quantum measurements: how can maximal knowledge be extracted? [PDF]

open access: yes, 2011
The extraction of information from a quantum system unavoidably implies a modification of the measured system itself. It has been demonstrated recently that partial measurements can be carried out in order to extract only a portion of the information ...

Manganese and zinc in acidic agricultural soils from Central Spain: Distribution and phytoavailability prediction with chemical extraction tests [PDF]

open access: yes, 2009
The extractability and distribution of manganese (Mn) and zinc (Zn) were evaluated in acidic agricultural soils from Central Spain. Both single (0.1 M hydrochloride [HCl] and 0.05 M ethylenediaminetetraacetate [EDTA]) and sequential extraction procedures
