Although shoot regeneration and transformation systems are well developed in rice callus, the regeneration frequency is commonly low and is cultivars-dependent (Huang et al., 2002; Khaleda and Al-Forkan 2006; Dabul et al., 2009).
Since RSS can have significant fluctuations even over short distances and/or small time intervals in a practical wireless environment due to complicated signal propagation mechanisms, therefore, the accuracy of RSS-based ranging is commonly low, which is also true for UWB signals.
Guidelines to prevent SSIs have been issued, but adherence is commonly low.
The number of men in the age group of 90 years and older is commonly low.
Primary B cell responses in the elderly are commonly low and short-lived, resulting in antibodies with low affinity [ 7].
Analysis is often hampered because TFs are known to be expressed at a very low level and fold changes are commonly low.
This facilitates mapping of gene-based markers, such as ESTs, which are commonly low in polymorphism [ 12] and are valuable tools for interspecies comparative studies.
Evidence of exposure can be high in pigs, chicken, and sheep raised outdoors; however, prevalence is commonly low in livestock raised in conventional high-biosecurity facilities [ 15, 16].
Second, scores in each QOL domain are commonly low, whereas the scores of females are much lower, indicating a poorer QOL than that of males.
While models that predict algal chlorophyll a as a function of nutrients can be useful, model strength is commonly low due to the overriding influence of stream habitat.
