The phrase "are characterized at a" is not correct in standard written English.
It seems to be a misconstruction and does not convey a clear meaning.
Example: "The species are characterized at a specific stage of development."
Alternatives: "are defined by" or "are described at".
The types were characterized at a resolution of 1 km2 based on elevation, relief amplitude, land cover, and ethnic population density.
Agricultural landscape types were characterized at a 1 km2 resolution based on Europe-wide datasets that represent land cover, landscape structure and land management intensity.
Synchronization can be characterized at a more refined level by looking at specific aspects of the shared consistent view of uniquely referenced objects: timeliness, currency, latency, consistency, coherence, and deterministic data access.
11C-Labeled tracers were characterized at a fundamental level involving isolation and mass detection of extremely low-abundance carbon-11 species along with the M + 1 carrier counterpart.
Figure 2 XRD patterns of the Co 3 O 4 nanoparticles and reference Co 3 O 4. The electrochemical properties of the air electrodes containing Co3O4 nanoparticles were characterized at a constant current density of 0.4 mA·cm-2 at 30°C. Figure 3a shows the initial voltage profile of the electrodes containing the Co3O4 nanoparticles in the voltage range of 4.35 to 2.3 V.
Mouse knockouts and a Zebrafish germline Dicer mutant have revealed important functions for microRNAs in the coordination of normal embryonic development [18], [19], but the individual vertebrate microRNAs are in general still enigmatic genetic objects and only a few have been characterized at a functional level.
The biochemical cascade that executes autophagy has originally been characterized at a molecular level in yeast (Saccharomyces cerevisiae) [ 7, 8].
Recent studies are beginning to shed light on how mycobacteria respond to nitrogen limitation and several regulators (e.g., GlnR, PII) have been characterized at a molecular level.
This suggests the existence of a mechanism, probably indirect and which remains to be characterized at a molecular level, of a coordinate regulation of these two important biological processes.
Of those that have been characterized at a mechanistic level, the Afterhours (Afh) mutant displayed considerably lengthened activity profiles under constant lighting conditions, with a free-running period of approximately 27 h (102, 103).
