Abstract:

We address the problem of topic mining and labelling in the domain of retail customer communications to summarize the subject of customers inquiries. The performance of two popular topic mining algorithms - Non-Negative Matrix Factorization (NMF) and Latent Dirichlet Allocation (LDA) &ndash; were compared, and a novel method to assign topic subject labels to the customer inquiries in an automated way was proposed. Experiments using a retailer&rsquo;s call center data verify the efficacy and efficiency of the proposed topic labelling algorithm. Furthermore, the evaluation of results fro

Abstract:

Printmaking, as an artistic and varied technique, involves a particular proofing and labelling process that ensures the reliability and quality of multiple impressions derived from a matrix. Printmakers face persistent challenges in achieving consistent print quality and accurate reproduction of the original design. The need for standard proofing and labelling procedures and tools for assessing and improving these issues poses a barrier to achieving the desired level of precision and consistency in print editions. This research aims to identify the standard proofing and labelling process termi

Abstract The reconstruction of a matrix having a pre-defined structure from given spectral data is known as an inverse eigenvalue problem (IEP). In this paper, we consider two IEPs involving the reconstruction of matrices whose graph is a special type of tree called a centipede. We introduce a special type of centipede called dense centipede.We study two IEPs concerning the reconstruction of matrices whose graph is a dense centipede from given partial eigen data. In order to solve these IEPs, a new system of nomenclature of dense centipedes is developed and a new scheme is adopted for labellin

Abstract:

Nutrition labelling is any description intended to inform consumers about the nutritional properties of a food product and has focused primarily on nutrients. However, literature has shown that the nutritional quality of packaged foods is not limited to the amount of nutrients, considering that individuals do not consume only nutrients separately, but rather the entire food matrix. Therefore, to analyze the nutritional quality of a packaged food, it is necessary to read its ingredients. This scoping review aims to discuss (1) the list of ingredients as a source of health and nutrition informat

Ultrastructural cytochemical tests demonstrate different domains in the matrix. Cell wall and matrix components are similar

Several experiments suggested that the reaction is increasing with time. Phosphate Buffer turned out to be a better option compared to Tris Buffer in terms of protein solubilization.

The results show that the spots as seen just after the labelling persist distinctly over the mitotic chromosomes as well as in the nuclei of the following cell cycles up to 44 hours after the pulse. Moreover, they are also present in the nuclei of differentiating cells. The spots over the mitotic

The objective of this study was to determine if differences in chondrocyte and ASC pellet growth result from differences in cell proliferation or in deposition of extracellular matrix.

With the increasingly urgent demand for map conflation and timely data updating, data matching has become a crucial issue in big data and the GIS community.

Abstract:

We show that the mechanism of fibronectin fibril formation on the blastocoel roof of the Xenopus embryo is comparable to that in other systems. Fibril assembly is inhibited by RGD peptide, by an amino-terminal fragment of fibronectin, and by cytochalasin B. When added exogenously, intact fibronectin, but not a 110 kDa cell binding fragment of fibronectin, is incorporated into fibrils. Thus, the blastocoel roof of Xenopus represents a valid model system for the study of fibronectin fibril formation in situ. Moreover, we show that fibril formation can be induced experimentally in this system. Ex

Abstract:

We have investigated biochemical and ultrastructural aspects of the nuclear matrix during the naturally synchronous cell cycle of Physarum polycephalum. The morphology of the in situ nuclear matrix exhibited significant cell cycle changes as revealed by electron microscopic examination, especially during the progression of nuclei through mitosis and S-phase. In mitosis the interchromatin matrix was found to be retracted to the nuclear periphery; during S-phase this interchromatin matrix gradually resembled, concomitant with the reconstruction of a nucleolar remnant structure. During the G2-per

Abstract. In this study we present a combined soil/canopy chamber system that allows the investigation of carbon flow through the atmosphere-plant-soil system via a 13CO2 canopy labelling approach – especially when using short vegetation such as tree saplings. The developed chamber system clearly separates soil and canopy compartment in order to (a) prevent physical diffusion of 13C tracer into the soil chamber during a 13CO2 canopy pulse labelling (b) study stable isotope processes in soil and canopy individually and independently. In combination with novel laser spectrometry, measuring CO2 (

Abstract:

Many aspects of the design of efficient crowdsourcing processes, such as defining workers bonuses, fair prices and time limits of the tasks, involve knowledge of the likely duration of the task at hand. In this work we introduce a new timesensitive Bayesian aggregation method that simultaneously estimates a tasks duration and obtains reliable aggregations of crowdsourced judgments. Our method, called BCCTime, uses latent variables to represent the uncertainty about the workers completion time, the tasks duration and the workers accuracy. To relate the quality of a judgment to the time a

Abstract:

Neuronal networks are balanced by mechanisms of homeostatic plasticity, which adjusts synaptic strength via molecular and morphological changes in the pre- and post-synapse. Here, we wondered whether the hyaluronic acid-based extracellular matrix (ECM) of the brain is involved in mechanisms of homeostatic plasticity. We hypothesized that the ECM, being rich in chondroitin sulfate proteoglycans such as brevican, which are suggested to stabilize synapses by their inhibitory effect on structural plasticity, must be remodelled to allow for structural and molecular changes during conditions of home

Abstract:

Specific antibody labelling indicates that phosphoproteins are present at microtubule-organizing centres, including the centrosome. We have employed electron spectroscopic imaging techniques that permit high-resolution elemental analysis of thin sections of intact cells to investigate the precise distribution of phosphorus and therefore phosphoproteins at the centrosome of Indian muntjac cells. We report that these proteins are localized to both the pericentriolar matrix and the centriole. The matrix contains an abundance of phosphorus and is associated with microtubule elements.

Abstract:

Soybean trypsin inhibitor (SBTI) inhibits the catalytic activity of serine proteases, and has been shown to bind to acrosin, an acrosomal hydrolase which is not exposed on the surface of macaque sperm until after the acrosome reaction. Following activation with caffeine and dibutyryl cAMP, cynomolgus macaque sperm were induced to acrosome react with calcium ionophore A23187 in the presence of SBTI and were fixed for ultrastructural observation. Transmission electron microscopy (TEM) revealed secondary labelling of anti-SBTI-IgG with colloidal gold in association with the acrosomal matrix and f
