Sentence examples for variations can exist from inspiring English sources

To explore PFC-NA synchrony with a better temporal resolution (to determine whether brief variations can exist), we assessed cross-covariance of membrane potential values in NA neurons with LFPs in the PFC using a ±200 ms sliding window (Figure 5B).

First, dysfunctions of lipid metabolism pathway caused by genetic variations can exist in those types.

These studies indicate that: striking Id variation can exist at diagnosis in untreated patients, the percentage of tumor represented by an individual variant may change with time and may differ between tumor sampled from different anatomical locations, and somatic variation appears to be responsible for the observed heterogeneity.

This technique typically leaves non-synaptic membranes (e.g. plasma membranes, neurotubules and vesicles) unstained, though considerable variation can exist from sample to sample.

Some variation can exist for good reasons such as differences in health needs or client preferences such as request for pain relief or planned place of birth.

The presence of two divergent haplotypes at a locus involved in pheromone biosynthesis illustrates how genetic variation can exist in moth mating systems without directly affecting patterns of reproduction.

Using single varieties as representatives for both barley and wheat may to some extent be an oversimplification as it is known that considerable variation can exist among varieties of the same species.

Once thought to manifest only in transient, exquisite, developmental gene expression programmes that were reset in the germ line, the discovery of transgenerational stability of novel epigenetic states showed that natural variation can exist outside the DNA sequence and cause heritable variation in phenotypes even in the absence of genetic variation (Richards et al. 2010; Ledón-Rettig 2013).

Such "nested' levels of variation can exist between closely related species, between populations of the same species, or even between sexes in ways that all contribute substantially to ecological success (Robinson et al. 1996; Foster et al. 1998; Jonsson and Skulason 2000; Parsons and Robinson 2007; Paradis and Magnan 2005; Riopel et al. 2008; Cooper et al. 2010).

Because considerable variation can exist in reported 2C values of CEN among studies (reviewed in Bennett and Leitch 1995 and references therein), we estimated 2C value of CEN by using H. deserticola (one of the sunflower hybrid species) as an external standard.

Further, variation can exist at the level of sequence and expression changes for these invasion ligands, suggesting a molecular basis for switching between the use of different invasion pathways, either for immune evasion, to change the parasite multiplication rate, and/or RBC selectivity.
