Benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo BPPV is a disorder arising from a problem in the inner ear Symptoms are repeated brief periods of vertigo with movement characterized by a spinning sensation upon changes in the position of the head This can occur with turning in bed or changing position Each episode of vertigo typically lasts less than one minute...

Spatial distribution of environmental DNA in a nearshore

Nov 29 2016 0183 32 We calculated two measures of diversity richness and evenness to ask if aggregate metrics of the eDNA community showed evidence of spatial patterning Richness is a measure of the number of distinct types of organisms present and so ranges from 1 only one taxon observed to S the number of taxa observed across all sampl...

Spatial Representations Are Specific to Different Domains

The prevailing use of aggregate data analysis has masked individual differences in the spatial representation of number and pitch The demonstration of subgroups with different response patterns likely accounts for the large variability and small differences between compatible and incompatible trials reported in previous SNARC and SMARC studies...

Spatial patterns of CTCF sites define the anatomy of TADs

Aug 12 2020 0183 32 Finally ignoring the top 25 of CTCF sites largely preserved the depletion of short-range 10 3 to 10 5 bp convergent patterns indicating that CTCF clusters made of the lowest three quartiles of CTCF sites still follow the same global spatial distribution imbalances as those made with the 25 top-ranking CTCF binding sites compare...

Spatial aggregation and soil process modelling

Apr 01 1999 0183 32 1 IntroductionThe modelling of soil processes takes place at various spatial scal For instance models of soil acidification have been built for the scale of plots regions and continents de Vries et al 1998 In a recent workshop of the International Soil Science Society Finke et al 1998 it was recognised that models describing the same process at different spatial scales can be...

Hyperspectral imaging applied to the waste recycling

Apr 30 2019 0183 32 The authors look at two important areas of recycling of waste materials concrete and plastics If aggregates are to be recycled from concrete the presence of pollutants plastics foams brick etc and the degree of removal of cement mortar from the aggregates must be assessed and monitored NIR hyperspectral imaging with PLS does a good job of both tasks...

Efficient aggregation over objects with extent

Finally we introduce the DA-tree that combines the advantages from each ECDF-B-tree We run experiments comparing the performance of the ECDF-B-trees the BA-tree and a traditional R -tree which has been augmented to include aggregation information on its index nodes over spatial datasets...

Algorithms for Fundamental Spatial Aggregate Operations

Spatial analysis

Spatial association is the degree to which things are similarly arranged in space Analysis of the distribution patterns of two phenomena is done by map overlay If the distributions are similar then the spatial association is strong and vice versa In a Geographic Information System the analysis can be done quantitativelyFor example a set of observations as points or extracted from...

Abstract Writing packet-processing programs for programmable switch pipelines is challenging because of their all-or-nothing nature a program either runs at line rate if it can fit within pipeline resources or does not run at all It is the compiler s responsibility to fit programs into pipeline resourc However switch compilers which use rewrite rules to generate switch machine code...
