These are all the fundamental particles that have been directly discovered; with the exception of a few of the bosons, all particles have mass.
In SemLinker, because the global concepts of ({mathcal{G}}) are predefined independently from the data sources, it is likely that a source schema is semantically incompatible with the concepts of ({mathcal{G}}), and therefore no implicit mappings can be directly discovered between a source schema S ij and a tagging concept g.
Nitrate also appears in this list but, in the form NO3−, has not yet been directly discovered on Mars.
In general, sequence-based searches are more efficient than function-based screening in prospecting for novel enzymes, since target genes can be directly discovered from metagenomic datasets using bioinformatics tools [ 33].
For the latter, target genes are cloned after being amplified from metagenomic DNA by using polymerase chain reaction with conserved sequences as primers; alternatively, they may be directly discovered from metagenome sequence databases using bioinformatics tools, subsequently amplified, and cloned in the appropriate expression systems.
More recently, a new adipokine, named retinol binding protein-4, has been discovered that is directly linked to the level of obesity-induced insulin resistance, both in cross-sectional [ 54, 55] and longitudinal studies [ 54, 56– 58].
The motor cortex a part of the cerebral cortex that is directly associated with movement—had been discovered only a century earlier, in 1870, when two researchers in Berlin probed the brains of dogs strapped to a dressing table, provoking muscle twitches in response.
As a student at Oxford in the late 1650s, he joined the laboratory of Robert Boyle, where, working with springs, he discovered that stress is directly proportional to strain--Hooke's law.
Remembering his old self and discovering that Sahjhan is directly responsible for all the pain he has endured, Connor slips to his original persona of 'demon-killer' and dispatches Sahjhan with ease.
We recently discovered "RNautophagy," an autophagic pathway in which RNA is directly taken up by lysosomes and degraded.
