We proposed a novel framework for video content understanding that uses rules constructed from knowledge bases and multimedia ontologies. Our framework consists of an expert system that uses a rule-based engine, domain knowledge, visual detectors (for objects and scenes), and metadata (text from automatic speech recognition, related text, etc.). We introduce the idea of modal keywords, which ar...

Transglutaminases (denoted TG or TGM) are externalized from cells via an unknown unconventional secretory pathway. Here, we show for the first time that purinergic signaling regulates active secretion of TG2 (also known as TGM2), an enzyme with a pivotal role in stabilizing extracellular matrices and modulating cell-matrix interactions in tissue repair. Extracellular ATP promotes TG2 secretion ...

RATIONALE Liver X receptors (LXRs) are oxysterol-activated nuclear receptors that are involved in the control of cholesterol homeostasis and inflammatory response. Human monocytes and macrophages express high levels of these receptors and are appropriate cells to study the response to LXR agonists. OBJECTIVE The purpose of this study was to identify new LXR targets in human primary monocytes ...

The double-to-single photoionization cross-section ratios of deuterated benzene (C6H3 D3) have been obtained in the photon energy region between 25 and 160 eV. The measurements were carried out on the 6m-TGM (042) beamline using an ion time-offlight spectrometer. In a previous experiment we have observed a modulation in the double-to-single photoionization ratio of C60, which could be used to d...

To evaluate the environmental impacts from large scale mercury mining (LSMM) and artisanal mercury mining (AMM), total mercury (THg) and methyl mercury (MeHg) were determined in mine waste, ambient air, stream water and soil samples collected from Wuchuan mercury (Hg) mining area, Guizhou, Southwestern China. Mine wastes from both LSMM and AMM contained high THg concentrations, which are import...

The presence of methyl alcohol or methanol (CH3OH) in several astrophysical environments has been characterized by its high abundance that depends on both the production rate and the destruction rate. In the present work, the photoionization and photodissociation processes of methanol have been experimentally studied, employing soft X-ray photons (100-310 eV) from a toroidal grating monochromat...

In order to develop a possible animal model to study H L A linked diseases of man, we established HLA-B27 transgenic mice (TGM). As aberrant and overexpression of M H C molecules can be toxic for cells, we aimed at obtaining a physiological expression of the human antigen and used a genomic 25kb Sal I fragment for embryo injection, coding for the H L A B * 2705 heavy chain. Five independent fou...

Five regional scale models with a horizontal domain covering the European continent and its surrounding seas, one hemispheric and one global scale model participated in an atmospheric mercury modelling intercomparison study. Model-predicted concentrations in ambient air were compared against mercury species observed at four monitoring stations in Central and Northern Europe and a station on the...

The 274 tRNA genes in Saccharomyces cerevisiae are scattered throughout the linear maps of the 16 chromosomes, but the genes are clustered at the nucleolus when compacted in the nucleus. This clustering is dependent on intact nucleolar organization and contributes to tRNA gene-mediated (tgm) silencing of RNA polymerase II transcription near tRNA genes. After examination of the localization mech...

A traffic impact sketch planning (TISP) model is presented for the estimation of likely travel demand generated by a major land-use development or redevelopment project. The proposed approach overcomes problems with non-behavioral transportation-related studies used in practice assessing design impacts on local transportation system. architectural development, terms number and type dwellings, b...
