Mercury fractionation in sediments downstream of the abandoned mine site of La Soterraña (Asturias, Spain)

open access: yesE3S Web of Conferences, 2013
Asturias (Northern Spain) has been an important mercury mining area during the twentieth century. The mining and smelting of ore has been the responsible for the large release of mercury to the aquatic and terrestrial environments in the area.

Parallel waveform extraction algorithms for the Cherenkov Telescope Array Real-Time Analysis [PDF]

open access: yes, 2015
The Cherenkov Telescope Array (CTA) is the next generation observatory for the study of very high-energy gamma rays from about 20 GeV up to 300 TeV. Thanks to the large effective area and field of view, the CTA observatory will be characterized by an ...

Time-sequential extraction of motion layers [PDF]

open access: yes2008 15th IEEE International Conference on Image Processing, 2008
A new time-sequential approach for motion layer extraction is presented. We assume that the scene can be described by a set of layers associated to affine motion models. In one or more key frames, the segmentation is obtained using a semi-automatic method.

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Isolation and characterization of acetylated LM-pectins extracted from okra pods [PDF]

open access: yes, 2014
Pectin was isolated by aqueous extraction at pH 6.0 or 2.0 from okra (Abelmoschus esculentus L.) pods. An isolation protocol was designed to extract pectin and to study the influence of the extraction pH on their composition and physicochemical ...

Keyphrase Extraction using Sequential Labeling

open access: yes, 2016
Keyphrases efficiently summarize a document's content and are used in various document processing and retrieval tasks. Several unsupervised techniques and classifiers exist for extracting keyphrases from text documents. Most of these methods operate at a phrase-level and rely on part-of-speech (POS) filters for candidate phrase generation. In addition,
