Thus in our procedure from time to time new clusters will be formed, composed only by a few data points, not sufficient to obtain a positive definite estimate of the corresponding covariance matrix using the classical sample covariance estimator.
The hydrocarbon molecules would compose only a very small part of the migrating fluids, a few hundred parts per million.
Like those found elsewhere on Okinawa, but not on mainland Japan, the cemeteries were composed of only a few plots; they consisted of mausoleums made of large, gray slabs of stone with rounded roofs resembling a turtle's shell.
The only exception is that the naive OLS yields a slightly higher failure rate when the portfolio under consideration is composed of only a few stocks.
The smaller particles are more susceptible to the effect of surface plasma treatment, since they are composed of only a few cells (between 1 and 3).
A rapid and efficient exfoliation process of protonated layered ferrititanates with lepidocrocite-like structure and formation of organic inorganic nanohybrids is performed starting from the nanosheets composed of only a few host layers and nanometric lateral dimensions using quaternary ammonium compounds.
Two of these lineages exhibit a general domed morphology, while the third, which is probably composed of only a few individuals at present, possesses the saddleback morphology (see [17] for a description of the domed and saddleback morphologies).
The number of repeat units is polymorphic in the general population, and an array can be composed of only a few to over one hundred repeat units, and therefore can encompass large genomic intervals.
However, most of these studies used mixtures composed of only a few odorants, even though the vast majority of scents that honeybees encounter in their natural environment are floral scents, which are complex blends of chemicals [9].
A total of 103 isolates gave no amplification or tDNA-PCR patterns composed of only a few and short tRNA intergenic spacers.
