Based on reconstructions of Prochlorococcus evolution from molecular phylogenies along with ecological observations, the emergence of the eNATL2A lineage coincided with the ability of Prochlorococcus to invade the surface mixed layer, albeit only in instances of deep vertical mixing that minimize the lengths of exposure to high light [17].
Number of days from emergence to date of observation was used to estimate age of first foraging.
The feedback between lateral root initiation and development/emergence was consistent with our analysis of plants with modified rates of initiation using gravistimulations [15], with the added observation that emergence was enhanced by gravistimulation.
This simulation behavior can be used to explain the well-known biological observation of emergence of phenotypically distinct subgroups within an isogenic (Kaern et al., 2005) cell population in response to an input stimuli (such as on exposure to external ligands).
The variations of the chromospheric line-of-sight velocity in the active region NOAA 11024 are studied before, during, and after a solar microflare on 2009 July 4. At the day of the observations the main emergence phase was in this active region.
An epidemiological analysis based on entropy is shown to explain empirical observations regarding the emergence of less pathogenic strains of human influenza during the antigenic drift phase.
The 7-valent pneumococcal conjugate vaccine (PCV7) markedly decreased resistant S. pneumoniae infections [8], [9], but recent observations suggest the emergence of non-vaccine serotypes with high levels of resistance to all approved antibiotics [10].
Without that flipping, the diffraction wouldn't have occurred, so observation confirms the emergence of the up-down-up-down pattern, Hulet says.
During a two-year ethnography of 47 older solo dwellers, this term captured one of the distinctive traits of the experience of living alone in older age in the U.S. The findings from semi-structured interviews and participant observation highlight the emergence of the notion of precariousness along three levels of analysis.
This observation supports the emergence of an original concept according to which biological order (cell patterning) leads to the optimized control of a downstream biological process (an apoptosis cascade).
