Annual Review of Ecology and Systematics, 1985
Hybrid zones are, roughly speaking, narrow regions in which genetically distinct populations meet, mate, and produce hybrids. They are often only a few hundred meters wide and yet may be several hundred kilometers long. They are found in a wide variety of organisms: Tables 1 and 2 list about 150 reasonably clear examples, in which there is a spatial ...

THE ANALYSIS OF MEIOSIS IN HYBRIDS. IV. PENTAPLOID HYBRIDS
Canadian Journal of Genetics and Cytology, 1981Models are developed which simulate expected chromosome pairing in pentaploid hybrids. Comparison of the various models with observed meiotic data allow the measurement of genomic affinity and therefore a new investigation of species and evolutionary relationships.

Optics and Lasers in Engineering, 1999
The synergism obtained by combining experimental information with numerical and/or theoretical concepts to stress analyze components made of isotropic and orthotropic (composite) materials is illustrated. Although applicable to a variety of experimental techniques, the paper emphasizes the use of measured moire, holographic, laser Doppler ...

Hybrid approaches for sentiment analysis
2011Sentiment Analysis is the task of extracting and classifying opinionated content in natural language texts. Common subtasks are the distinction between opinionated and factual texts, the classification of polarity in opinionated texts, and the extraction of the participating entities of an opinion(-event), i.e. the source from which an opinion emanates

pyHybrid Analysis: A Package for Semantics Analysis of Hybrid Systems
2013 Euromicro Conference on Digital System Design, 2013Hybrid automata naturally represent systems that exhibit a mixed discrete-continuous behaviours. The undecidability of the reach ability problem over them constrains the chances of punctually investigating this kind of formalism. Established that this negative result and the presence of artifacts, which do not correspond to any observable phenomena ...

Cancer Genetics and Cytogenetics, 2005
In order to characterize the chromosomal alterations in ameloblastomas, a combination of comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) techniques was performed on 9 tumors. Chromosomal alterations including a gain at 1q and losses at 1pter, 10q, and 22q could be detected by CGH only in 1 tumor.

An Analysis of Hybridization in Liatris
Brittonia, 1967Liatris aspera andL. spicata are remotely related species, and rarely have an opportunity to hybridize because of different flowering periods and ecological tolerances. Seasonal and ecological barriers have been surmounted in a population in southern Cook County, Illinois, which has resulted in extensive hybridization.

Segmentation of hybrid motions via hybrid quadratic surface analysis
Tenth IEEE International Conference on Computer Vision (ICCV'05) Volume 1, 2005In this paper, we investigate the mathematical problem underlying segmentation of hybrid motions: given a series of tracked feature correspondences between two (perspective) images, we seek to segment and estimate multiple motions, possibly of different types (e.g., affine, epipolar, and homography).

Analysis of hybrid Petri nets based on the hybrid state equation
SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002In this paper we are interested in a mathematical description of the class of hybrid systems, which can be modelled by hybrid Petri nets (HPN). A state space model using the conventional algebra for the continuous subsystem and the minplus algebra for the discrete subsystem is given, This model is used in the analysis of a special class of HPN.

Comparative genomic hybridization analysis of hepatoblastomas
Genes, Chromosomes and Cancer, 2000Prior cytogenetic analyses of hepatoblastomas have shown the most common recurring abnormalities to be trisomy for chromosomes 2 and 20, and a recurrent translocation involving chromosomes 1 and 4 identified in a minority of cases. Four cases have shown double minute chromosomes, which provide cytogenetic evidence for gene amplification, although no ...
