Financial data includes "pre-trade" such as bid-ask data necessary to price a financial instrument and post-trade data such as the last trade price and other transaction data. From ticker tape to television cameras, from databases to websites this multibillion-dollar industry provides data utilized in the financial sector.
The color and size can vary a great deal among the subspecies described. Geographical location is a good key to establishing the subspecies, as each one has a distinct geographical range. The reticulated python lives in rainforests, woodlands, and nearby grasslands. It is also associated with rivers and is found in areas with nearby streams and ...
A table is an arrangement of columns and rows that organizes and positions data or images. Tables can be created on Wikipedia pages using special wikitext syntax, and many different styles and tricks can be used to customise them.
To quantify the number of cells in a culture, the cells can be simply plated on a petri dish with growth medium. If the cells are efficiently distributed on the plate, it can be generally assumed that each cell will give rise to a single colony or Colony Forming Unit (CFU). The colonies can then be counted, and based on the known volume of ...
Determining the viable cell count is important for calculating dilutions required for the passaging of cells, as well as determining the size and number of flasks needed during growth time. It is also vital when seeding plates for assays, such as the plaque assay , [ 2 ] because the plates need a known number of live replicating cells for the ...
It is important first, to homogenize milk, heating it in a water bath at 40 °C for somatic cells that float to the surface along with the fat. The laboratory apparatus must be clean but not necessarily sterile, since the method is based on cell count and asepsis is not accurate. If later it is going to make detailed microbiological analyzes on ...
Graphical examination of count data may be aided by the use of data transformations chosen to have the property of stabilising the sample variance. In particular, the square root transformation might be used when data can be approximated by a Poisson distribution (although other transformation have modestly improved properties), while an inverse sine transformation is available when a binomial ...
For data in which the maximum key size is significantly smaller than the number of data items, counting sort may be parallelized by splitting the input into subarrays of approximately equal size, processing each subarray in parallel to generate a separate count array for each subarray, and then merging the count arrays.
