We use non-parametric and semi-parametric scale readjustment methods as well as a more sophisticated Compound Hierarchical Ordered Probit (CHOPIT) model in order to compare these results against the ones obtained using the non-adjusted measure.
And most tires are made of sophisticated rubber compounds that can withstand heat and friction.
Traces of a large amount of blood that had been cleaned up were detected by police using a sophisticated chemical compound, she said.
A further consequence is also that simple substructure searching, e.g. using the androstane scaffold as a substructure query, will lead to wrong classifications and should not be used for sophisticated ontological compound classification tasks.
With today's sophisticated methods, chemical compounds can be determined in parts per billion.
— and drug use has moved from basic amphetamines to compounds so sophisticated that they defy detection.
Analysts say the group, which surfaced in Egypt's restive Sinai Peninsula last year, is probably responsible for most of the more complex and sophisticated operations against security compounds in Egypt since the military coup.
He and his colleagues went on to elucidate the chemistry of boron compounds, using sophisticated quantum mechanical calculations to describe the structure of molecules and to predict how they would react chemically.
From a technical viewpoint, the performance of our method could be improved by using more sophisticated similarity functions for compounds and proteins, such as kernel functions designed for genomic sequences and chemical structures (Schölkopf et al., 2004).
Dissatisfied with the research at the time, which measured toxic substances outside the body and then made inferences about their effects, she began using sophisticated molecular techniques to measure compounds called polycyclic aromatic hydrocarbons, or PAH — which are plentiful in tobacco smoke — in the body.
In the end, the map analogy is important here–just as world maps do not have the resolution necessary to show trees and houses, large-scale exploratory mapping of the chemical universe is not going to translate into sophisticated predictive models for all compounds captured, and the intended application very much determines the computational approach used.
