Edge Detection and Ridge Detection with Automatic Scale Selection

by Tony Lindeberg - CVPR'96 , 1996
"... When extracting features from image data, the type of information that can be extracted may be strongly dependent on the scales at which the feature detectors are applied. This article presents a systematic methodology for addressing this problem. A mechanism is presented for automatic selection of ..."

of the strength of the edge response is locally maximal over scales. An important property of this definition is that it allows the scale levels to vary along the edge. Two specific measures of edge strength are analysed in detail. It is shown that by expressing these in terms of &

Dendritic cells use macropinocytosis and the mannose receptor to concentrate macromolecules in the major histocompatibility complex class II compartment: down-regulation by cytokines and bacterial products.J. Exp. Mecl

by Federica Sallusto, R Marina Cella, Carlo Danieli, Antonio , 1995
"... We have previously demonstrated that human peripheral blood low density mononuclear cells cultured in granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4 develop into dendritic cells (DCs) that are extremely efficient in presenting soluble antigens to T ceils. To identif ..."

uptake via macropinocytosis. In contrast to what has been found with other cell types, macropinocytosis in DCs is constitutive and allows continuous internalization of large volumes of fluid. The second mechanism of capture is mediated via the mannose receptor (MR), which is expressed at high levels

Thematic relations as links between nominal reference and temporal constitution

by Manfred Krifka , 1992
"... This paper treats the correspondence between the reference type of NPs (i.e., mass nouns, count nouns, measure constructions, plurals) and the temporal constitution of verbal predicates (i.e., activities, accomplish-ments). A theory will be developed that handles the well known influence of the refe ..."

of the reference type of NPs in argument positions on the temporal consti-tution of the verbal expressions, assuming an event semantics with lattice structures and thematic roles as primitive relations between events and ob-jects. Some consequences for the theory of thematic roles will be discussed, and the effect

Nominal Reference, Temporal Constitution and Quantification in Event Semantics

by Manfred Krifka - Semantics and Contextual Expression, Foris, Dordrecht , 1989
"... It is by now a well-known topic in semantics that there are striking similarities between the meanings of nominal and verbal expressions, insofar as the mass:count distinction in the nominal domain is reflected in the ate1ic:telic distinction in the verbal domain (cf. Leisi 1953, Taylor 1977, ..."

A Network of Local and Redundant Gene Regulation Governs Arabidopsis Seed Maturation

by François Parcy A
"... [LEC1], and LEC2) control most aspects of seed maturation, such as accumulation of storage compounds, cotyledon identity, acquisition of desiccation tolerance, and dormancy. The molecular basis for complex genetic interactions among these regulators is poorly understood. By analyzing ABI3 and FUS3 e ..."
Abstract - Add to MetaCart
lec2 phenotypes can be rescued by ABI3 or FUS3 constitutive expression. In addition, ABI3 and FUS3 positively regulate themselves and each other, thereby forming feedback loops essential for their sustained and uniform expression in the embryo. Finally, LEC1 also positively regulates ABI3 and FUS3

Design patterns: Abstraction and reuse of object-oriented design

by Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides - ECOOP '93 , 1993
"... We propose design patterns as a new mechanism for expressing object-oriented design experience. Design patterns identify, name, and abstract common themes in objectoriented design. They capture the intent behind a design by identifying objects, their collaborations, and the distribution of responsi ..."

Cytotoxic T lymphocyte-associated antigen 4 plays an essential role

by Simon Read, Vivianne Malmström, Fiona Powrie - in the function of CD25 � CD4 , 2000
"... It is now clear that functionally specialized regulatory T (Treg) cells exist as part of the normal immune repertoire, preventing the development of pathogenic responses to both self- and intestinal antigens. Here, we report that the Treg cells that control intestinal inflammation express the same p ..."

cytotoxic T lymphocyte–associated antigen 4 (CTLA-4), as well as secretion of the immune-suppressive cytokine transforming growth factor �. Strikingly, constitutive expression of CTLA-4 among CD4 � cells was restricted primarily to Treg cells, suggesting that CTLA-4 expression by these cells is involved

The nuclear DNA base 5-hydroxymethylcytosine is present

by Skirmantas Kriaucionis, Nathaniel Heintz - in Purkinje neurons and the brain. Science 324:929–30
"... Despite the importance of epigenetic regulation in neurological disorders, little is known about neuronal chromatin. Cerebellar Purkinje neurons have large and euchromatic nuclei, whereas granule cell nuclei are small and have a more typical heterochromatin distribution. While comparing the abundanc ..."

the abundance of 5-methylcytosine in Purkinje and granule cell nuclei, we detected the presence of an unusual DNA nucleotide. Using thin-layer chromatography, high-pressure liquid chromatography, andmass spectrometry, we identified the nucleotide as 5-hydroxymethyl-2′-deoxycytidine (hmdC). hmdC constitutes 0

Data complexity of query answering in description logics

In particular, we are interested in characterizing the FOL-reducibility and the polynomial tractability boundaries of conjunctive query answering, dependi ..."

Mammalian transcription factor ATF6 is synthesized as a transmembrane protein and activated by proteolysis in response to endoplasmic reticulum stress

by Kyosuke Haze, Hiderou Yoshida, Hideki Yanagi, Takashi Yura, Kazutoshi Mori - Mol. Biol. Cell , 1999
"... The unfolded protein response (UPR) controls the levels of molecular chaperones and enzymes involved in protein folding in the endoplasmic reticulum (ER). We recently isolated ATF6 as a candidate for mammalian UPR-specific transcription factor. We report here that ATF6 constitutively expressed as a ..."
