The procedure of point cloud preparation - data filtering and subsampling, as well as what file formats are available - is considered. ...
Abstract Cellular function in tissue is dependent on the local environment, requiring new methods for spatial mapping of biomolecules and cells in the tissue context1. The emergence of spatial transcriptomics has enabled genome-scale gene expression mapping2,3,4,5, but the ability to capture spatial epigenetic information of tissue at the cellular level and genome scale is lacking. Here we ...
Such manual analysis can be subjective, costly, and time-intensive, which causes delays in data availability, limits the breadth of application, and can result in poor subsampling of measurements. As a result, samplers capable of autonomous and continuous real-time (RT) or near-RT analysis have become increasingly common. ...
Waves breaking and bubbles popping at the Earth’s surface eject seawater droplets into the atmosphere 10’s of nanometers to 100’s of micrometers in diameter, called sea spray aerosol (SSA). These aerosols are tiny subsamples of the ocean’s surface, and the ocean has high numbers of heterotrophic bacteria, more than a million per milliliter, in addition to ...
The grain was removed from each cob and weighed. A subsample of 100 grains was selected from the grain from each cob and weighed to determine mean grain size per cob. ...
Compared to previous regional studies in Denmark, a general increase in extreme rainfall intensity for durations up to 1 hour is found, whereas for larger durations both increases and decreases are seen. A subsample analysis is conducted to evaluate the impacts of non-stationarities in the rainfall data. ...
A sewage water sample was divided in 2-μL subsamples for testing by all three culture-based methods. All growing colonies were harvested and subjected to 16S rRNA sequencing. ...
Period change analysis gives temperature and precipitation changes for 55 general circulation models which are then subsampled to produce four future states per basin. Results indicate an increase in temperature between 3.0 and 6.2 °C and an 18% decrease to 26% increase in precipitation. ...
Then, 635 1-L well water samples were divided into 100 mL subsamples for testing by all four methods. Test results showed that 70.5, 52.7, 36.4, and 23.3% of the non-E. coli total coliform strains and 94.7, 94.7, 89.5, and 89.5% of the 19 E. coli strains yielded a positive signal with the four methods, respectively. ...
Both systems enabled detection of endospores at a concentration level of 100 spores in 100 liters, by analyzing the totality of the volume, whereas the standard method did not highlight the presence of spores, analyzing only 100 mL subsamples. In addition, experiments on a sand filtration pilot confirmed that the concentration calculation using the standard method is not ...
Glochidia of 7 mussel species were isolated from females, placed in water, and subsampled daily for 2–5 d. Viability, when ≥ 90%, was generally a good predictor of infectivity; however, when viability was 90%. ...

Mixes were saturated, gravitationally drained, incubated under isothermal ventilation having mean vapor pressures of 1.78, 2.19, or 2.45 kPa, and reirrigated when matric tension exceeded 300 kPa. After 138 d, rootzone subsamples were eluted of particulate OM before measuring mineral-adsorbed hydrocarbon content (MAHC) by infrared spectroscopy. ...
Development of core collections is an effective tool to extensively characterize large germplasm collections, and the use of a mini-core subsampling strategy further increases the effectiveness of genetic diversity analysis at detailed phenotype and molecular levels. ...
Most methods require compositing several subsamples to control measurement error, and few are feasible with loose, dry soils. ...
Subsample wet weight is usually taken with a portable platform balance often times situated on the tailgate of a truck. ...
Kriging is proposed as a means to get insights into numerical data on local variances: large-volume samples in elemental analysis may be an approach to avoid problems due to subsampling and homogenisation. The data comparability is discussed in terms of geography-related variability in biomonitor vitality: the discussion underlines that the comparability in vitality should ...
However, this process is time consuming and is usually based on a relatively small subsample of pods from peanut fields. Research was conducted during 2003–2005 to determine if reflectance of the peanut canopy, using multispectral imaging (350–2500 nm), could be used as an indicator of pod maturation. ...
Abstract We collected 50 subsamples of the moss Scleropodium purum from each of three sampling sites and determined the concentrations of As, Cd, Cu, K, Hg, Ni, Pb, Se, and Zn in each subsample. We then calculated the number of subsamples required to determine significant differences in the mean concentrations of two sampling sites. ...
