Semi-supervised approaches have been applied to conquer limitations of supervised and unsupervised methods when labeled data is scarce and obtaining large amounts of labeled data is expensive and time consuming [ 16, 17].
Since data from the Girona Registry was scarce, to obtain stable estimates of the Catalan survival functions by age group and disease extension, we derived the Catalan survival time (pdfs) from survival data for the US in calendar years 1975-1979.
"Nature is incredibly clever when it comes to obtaining scarce nutrients," says Sunda, whose work was described in the 6 October 2009 issue of the Proceedings of the National Academy of Sciences.
That is not so much the case in the United States, where airlines like Southwest have fought to obtain scarce takeoff and landing slots in congested cities like New York.
While this alone does not prove that Stylidium species are themselves carnivorous, the hypothesis is that the association arose because Stylidium species and the known carnivorous plants obtain scarce nutrients using the same source, namely captured insects.
In this association, the hyphae of the fungus permeate large volumes of soil and obtain scarce elements, especially phosphorus which is often limiting for plant growth which they pass on to the plant in exchange for metabolic products of the plant's photosynthesis.
As histopathological information on well-characterized SScPAH patients is scarce, the results obtained here provide valuable exploratory information.
Resources are kept perpetually scarce, while the procedures for obtaining them (achieving "platinum status," for example) are kept infernally confusing.
Particular attention is paid to shortage of information and to strategies for gaining control of scarce supplies of labor (through obtaining 'rights in people').
As BRNs are an especially scarce resource in nursing homes, obtaining more information on how to allocate them in the nursing home is desirable.
Biophysical methods are increasingly utilized in the structural studies of S-layers, and together with computer modelling-based methods they will probably allow for high-resolution structures of Lactobacillus S-layer proteins, which currently are scarce owing to difficulties in obtaining high-quality crystals for X-ray crystallography.
