An alternative approach for fluorescence measurements is to use small fiber optic probes that utilize a single optical fiber to both deliver excitation light and collect emitted fluorescence [ 5, 17– 21]; such a measurement results in a localized sampling volume, with the majority of the collected signal originating very close to the probe face [ 18].
While mid-Cretaceous Laurasia may not have supported modern tropical rain forest as we know it today in terms of composition and diversity, the evolutionary histories captured in multiple tropical rain forest-restricted lineages suggest that the tropical rain forest biome, or something very close to it, originated well before the end of the Cretaceous (65 Ma).
These currents, originating in active membrane, are functionally significant very close to their site of origin but must be considered incidental at any distance from it.
These species were represented by 539 sequences, of which 221 lineages were identified after discarding 318 redundant sequences that corresponded to sequences belonging to already included lineages and originating from the same or very close localities as those already in the analysis (Table S1).
As a written record, Tweets are very close to the originating thoughts.
Mr. McGuinness, who joined the crowd, denied that he was carrying a gun at the time of the shootings and said that the allegation originated with "British agents or with people who were very close to British agents".
In each population, the parents that gave rise to the F1 male originated from the same barn, or from locations in very close proximity to each other.
Most of the chemical shifts originating from amino acids in both complexes are almost exactly the same, except for those very close to the site of complexation, i.e., originating from the two last glutamic acid moieties.
Four cDNA isoforms were isolated and sequenced, that originate from an alternative usage of three variants of exon 4, revealing a size very close to the major human FHIT cDNAs.
