  • system
  • This system may be more efficacious at stopping a cluster headache attack than the currently prescribed oxygen delivery system. (clinicaltrials.gov)
  • This delivery system may be better at stopping a cluster headache attack than the continuous flow model as it can support hyperventilation which can enhance cerebral arterial vasoconstriction via a state of hyperoxia and hypocapnia. (clinicaltrials.gov)
  • minutes
  • In the currently recommended dosing strategy of continuous flow 100% oxygen given via a non-rebreather face mask at 7-15L/min, the time to improvement can sometimes take upwards of 20-30 minutes and is not effective for all cluster headache sufferers. (clinicaltrials.gov)
  • intervals
  • This study evaluates the clustering of hospitalization rates for stroke and compares this clustering with two different time intervals 2009-2010 and 2012-2013, corresponding to the beginning of the French National Stroke Plan 2010-2014. (hindawi.com)

  • methodology
  • It develops a methodology for clustering a large number of developing countries, identifying and ranking their welfare regimes, assessing their stability over the decade 1990-2000, and relating these to important structural variables. (bath.ac.uk)
  • depend
  • The appropriate clustering algorithm and parameter settings (including parameters such as the distance function to use, a density threshold or the number of expected clusters) depend on the individual data set and intended use of the results. (wikipedia.org)
  • The specifics of the transformation from r̂ to Ĉ and the structure of C depend on the clustering method. (pnas.org)
  • neural networks
  • the most well known unsupervised neural network is the self-organizing map and these models can usually be characterized as similar to one or more of the above models, and including subspace models when neural networks implement a form of Principal Component Analysis or Independent Component Analysis . (wikipedia.org)
  • genes
  • The approach utilizes an analysis of variance model to achieve normalization and estimate differential expression of genes across multiple conditions. (pnas.org)
  • Specifically, an assortment of clustering techniques have been developed and applied to identify groups of genes with similar patterns of expression ( 3 - 6 ). (pnas.org)
  • Consider two genes that cluster together. (pnas.org)
  • Are the patterns of expression for these genes sufficiently similar beyond any reasonable doubts raised by the uncertainty of the estimates, or could these genes have clustered together by chance? (pnas.org)
  • By "clustering" genes, we mean organizing genes into groups, which may be predefined or data-driven, or organizing genes into a structure to represent some measure of distance between them. (pnas.org)
  • This is the case for our example below, where genes are clustered by calculating the correlation of an observed profile with a collection of fixed target profiles. (pnas.org)
  • displaystyle
  • These functions are both determined by finding the smallest cluster C {\displaystyle C} that contains both item i {\displaystyle i} and at least one larger-numbered item. (wikipedia.org)
  • Quantitative
  • Analysis of quantitative trait loci, or QTL, is a more recent addition to quantitative genetics, linking it more directly to molecular genetics. (wikipedia.org)

  • species
  • We can visualize the result of running it by turning the object to a dendrogram and making several adjustments to the object, such as: changing the labels, coloring the labels based on the real species category, and coloring the branches based on cutting the tree into three clusters.

  • The Soviet Army has based much of its post-war doctrine on the war experience, and had devoted considerable resources to the analysis of troop density, including these in almost all considerations of wartime operations. (wikipedia.org)
  • The physical density of troops in the area of combat is not reflective of the average value for any given command because dispersion of troops tends to follow terrain and tactical considerations of the combat planning, and actual location of troops tends to be in clusters of positions.
