Some neuromyotonia cases do not only improve after plasma exchange but they may also have antibodies in their serum samples against voltage-gated potassium channels.

A very small proportion of cases with NMT may develop central nervous system findings in their clinical course, causing a disorder called Morvan's syndrome and they may also have antibodies against potassium channels in their serum samples.

When these samples are independent observations of the same random event they can be called independent identically distributed random variables.

Firms with superior software thus have an incentive to offer samples, except if their product is already well known, or if they do not want to be listed in direct competition with other products on shareware repositories.

The use of any parametric model is viewed skeptically by most experts in sampling human populations: " most sampling statisticians, when they deal with confidence intervals at all, limit themselves to statements about based on very large samples, where the central limit theorem ensures that these will have distributions that are nearly normal.

The task of summarising statistical data in conventional forms ( also known as descriptive statistics ) is considered in theoretical statistics as a problem of defining what aspects of statistical samples need to be described and how well they can be described from a typically limited sample of data.

" In / Flux ", with its mixed up bpms, spoken word samples, strings, melodies, bizarre noises, prominent bass, and slow beats, gave the listener the impression they were on a musical trip, according to Pemberton.

* The following samples presumably predate the Lord of the Rings, but they were not explicitly dated: DTS 16, DTS 17, DTS 18 – Elvish Script Sample I, II, III, with parts of the English poems Errantry and Bombadil, first published in the Silmarillion Calendar 1978, later in Pictures by J. R. R. Tolkien, as well as DTS 23 – So Lúthien, a page of the English Lay of Leithan text facsimiled in The Lays of Beleriand: 299.

The suggested subspecies were never widely used or validated by field biologists ; the described morphological differences were small enough that they could have resulted from simple variation in non-representative samples.

These estimators have a significant drawback in that they will drop a significant amount of sample data as only 1 / n of the available samples is being used.

Formant synthesizers are usually smaller programs than concatenative systems because they do not have a database of speech samples.

Composite samples were collected at weekly intervals.

The composite samples were normally collected over a 6-hr. period, but an occasional 24-hr. composite was made.

Grab samples were collected from the existing oxidation pond to determine its operating conditions.

On the surface, Young and Duke collected of lunar samples for return to Earth, while Command Module Pilot Ken Mattingly orbited in the Command / Service Module above to perform observations.

After ALSEP deployment, Young and Duke collected samples in the vicinity.

After opening the hatch and reuniting with Mattingly, the crew transferred the samples Young and Duke had collected on the surface into the CSM for transfer to Earth.

Stool and swab samples collected in the acute stage of the disease, before antibiotics have been administered, are the most useful specimens for laboratory diagnosis.

An analysis of the sediment samples collected by Kaiko found large numbers of simple organisms at.

After an oil drilling operation in 1903 in Dexter, Kansas, produced a gas geyser that would not burn, Kansas state geologist Erasmus Haworth collected samples of the escaping gas and took them back to the University of Kansas at Lawrence where, with the help of chemists Hamilton Cady and David McFarland, he discovered that the gas consisted of, by volume, 72 % nitrogen, 15 % methane ( a combustible percentage only with sufficient oxygen ), 1 % hydrogen, and 12 % an unidentifiable gas.

He found the gas in each of the 50 air samples that he collected but, not realising that the breakdown of CFCs in the stratosphere would release chlorine that posed a threat to the ozone layer, concluded that the level of CFCs constituted " no conceivable hazard ".

During the second expedition, the unmanned vehicle Kaikō collected mud samples from the seabed.

Apart from meteorites fallen onto the Earth, two tiny fragments of asteroids were found among the samples collected on the Moon ; these were the Bench Crater meteorite ( Apollo 12, 1969 ) and the Hadley Rille meteorite ( Apollo 15, 1971 ).

Samples are collected and statistics are calculated from the samples so that one can make inferences or extrapolations from the sample to the population.

Radiocarbon results obtained from samples collected during these excavations indicate that occupation of Skara Brae began about 3180 BCE with occupation continuing for about six hundred years.

Mass correlation spectrometry can be performed as an office-based test since breath samples are continuously collected, and results are provided immediately within minutes.

During 1996 – 1997 water samples were collected at various points throughout the caves and showed different chemical compositions.

Isolates collected from the three children and from samples taken at the farm were indistinguishable, demonstrating evidence of the link between the farm and the children's illness.

The conclusion was supported by a case-control study, environmental sampling, and laboratory analysis of samples collected from the fair and members of the outbreak.

Depending on the specific parameters unique to each patient's diagnostic plan, samples collected for analysis can range from whole blood, urine, plasma, serum, to even packed red blood cells.
