AnABlast: Re-searching for Protein-Coding Sequences in Genomic Regions
2019
AnABlast is a computational tool that highlights protein-coding regions within intergenic and intronic DNA sequences which escape detection by standard gene prediction algorithms. DNA sequences with small protein-coding genes or exons, complex intron-containing genes, or degenerated DNA fragments are efficiently targeted by AnABlast. Furthermore, this algorithm is particularly useful in detecting protein-coding sequences with nonsignificant homologs to sequences in databases. AnABlast can be executed online at http://www.bioinfocabd.upo.es/anablast/ .
A Combined Fuzzy and Probabilistic Data Descriptor for Distributed CBIR
2009
With the wide diffusion of digital image acquisition devices, the cost of managing hundreds of digital images is quickly increasing. Currently, the main way to search digital image libraries is by keywords given by the user. However, users usually add ambiguos keywords for large set of images. A content-based system intended to automatically find a query image, or similar images, within the whole collection is needed. In our work we address the scenario where medical image collections, which nowadays are rapidly expanding in quantity and heterogeneity, are shared in a distributed system to support diagnostic and preventive medicine. Our goal is to produce an efficient content-based descript…
Clustering techniques for personal photo album management
2009
In this work we propose a novel approach for the automatic representation of pictures achieving at more effective organization of personal photo albums. Images are analyzed and described in multiple representation spaces, namely, faces, background and time of capture. Faces are automatically detected, rectified and represented projecting the face itself in a common low-dimensional eigenspace. Backgrounds are represented with low-level visual features based on RGB histogram and Gabor filter bank. Faces, time and background information of each image in the collection is automatically organized using a mean-shift clustering technique. Given the particular domain of personal photo libraries, wh…
CellLineNavigator: a workbench for cancer cell line analysis
2012
The CellLineNavigator database, freely available at http://www.medicalgenomics.org/celllinenavigator, is a web-based workbench for large scale comparisons of a large collection of diverse cell lines. It aims to support experimental design in the fields of genomics, systems biology and translational biomedical research. Currently, this compendium holds genome wide expression profiles of 317 different cancer cell lines, categorized into 57 different pathological states and 28 individual tissues. To enlarge the scope of CellLineNavigator, the database was furthermore closely linked to commonly used bioinformatics databases and knowledge repositories. To ensure easy data access and search abili…
Graph-grammar semantics of a higher-order programming language for distributed systems
1994
We will consider a new tiny, yet powerful, programming language for distributed systems, called DHOP, which has its operational semantics given as algebraic graph rewrite rules in a certain category of labeled graphs. Our approach allows to separate actions which affect several processes from local changes such as variable bindings. We also sketch how to derive an implementation from this specification.
Jugement de la couleur des carcasses en abattoir. Eléments d’objectivation de la notation experte de la couleur des viandes de gros bovins Charolais
2016
Evaluation of carcass color at the slaughterhouse Expert notation is the reference method for the evaluation of bovine meat color, notably for quality. A total of 140 Charolais carcasses were scored at the slaughterhouse on a color scale going from 1 (too light) to 5 (too dark). These expert scores were compared to three types of instrumental data (L*a*b / RVB referential; image shooting with image processing / chromameter). Amongst the instrumental measurements, the values obtained after image processing of the whole muscle seems to be better associated with the scores obtained for color by experts than the scores obtained with the chromameter for which the zone of the muscle analyzed is m…
Selective MicroRNA-Offset RNA Expression in Human Embryonic Stem Cells
2015
Small RNA molecules, including microRNAs (miRNAs), play critical roles in regulating pluri-potency, proliferation and differentiation of embryonic stem cells. miRNA-offset RNAs (moRNAs) are similar in length to miRNAs, align to miRNA precursor (pre-miRNA) loci and are therefore believed to derive from processing of the pre-miRNA hairpin sequence. Recent next generation sequencing (NGS) studies have reported the presence of moRNAs in human neurons and cancer cells and in several tissues in mouse, including pluripotent stem cells. In order to gain additional knowledge about human moRNAs and their putative development-related expression, we applied NGS of small RNAs in human embryonic stem cel…
Some observations on the use of HamNoSys (Hamburg Notation System for Sign Languages) in the context of the phonetic transcription of children’s sign…
2005
This paper discusses the use of the HamNoSys notation (Hamburg Notation System for Sign Languages) for the transcription of children’s signing. The notation system will be briefly described and some former descriptions of the acquisition of sign language phonology presented. The project in which HamNoSys was used is then described briefly followed by a description of the problems encountered while using the notation. Furthermore some proposals as to how to further develop the notation will be made. In conclusion the instrument can be said to be useful and, especially if revised, will be invaluable in further research.
Comfort, the acceptable face of luxury - an eighteenth-century cultural etymology
2014
The introduction of modern amenities into European homes has been extensively studied by sociologists and historians, who have stressed the rise in consumption during the Georgian period.1 Some objects, such as mirrors, stoves, or umbrellas, were made available by technical innovations; others, such as tea, sugar, or mahogany furniture, became accessible thanks to the expansion of global trade. Other amenities, such as carpets, curtains, or marble chimney-pieces, were no longer restricted to the aristocracy, as living standards rose.2 As the British nation became richer, the number of affluent households grew as did their capacity to spend more on material objects. This signaled a change in…
Database to Ontology Mapping Patterns in RDB2OWL Lite
2016
We describe the RDB2OWL Lite language for relational database to RDF/OWL mapping specification and discuss the architectural and content specification patterns arising in mapping definition. RDB2OWL Lite is a simplification of original RDB2OWL with aggregation possibilities and order-based filters removed, while providing in-mapping SQL view definition possibilities. The mapping constructs and their usage patterns are illustrated on mapping examples from medical domain: medicine registries and hospital information system. The RDB2OWL Lite mapping implementation is offered both via translation into D2RQ and into standard R2RML mapping notations.
