Even if patient-ventilator asynchrony is very common, studying this phenomenon remains a challenge in daily clinical practice [ 8].
As convergence motivates us to study absolute and strong convergence, similarly it was very common to study the ideas of absolute almost and strong almost convergence after the concept of almost convergence.
To identify microemulsion phase boundary, it is very common to study phase behavior in the laboratory.
In dielectrics, glasses and networked liquids it is very common to study noise spectra with extended power-law regions to gather useful information.
Although the use of alginic acid derivatives is very common, many studies on amino acid polycations have been changing during the last 25 years (Calafiore and Basta 2014).
In AECOPD, ECG changes are very common, and studies demonstrate a high frequency of finding a new abnormality on ECG from baseline.
Such data have become very common in studies because of the increased interest in qualitative variables and probably also because of the WHO recommendation of quality-of-life assessments in research and clinical practice.
However, if all men harbouring a focal carcinoma in their prostates were classified as false negative, the situation would change dramatically as this has been very common in studies based on autopsy (Breslow et al, 1977; Kabalin et al, 1989) and cystoprostatectomy specimens or prostate tissue removed in transurethral prostatectomy (Montie et al, 1989; Merrill and Wiggins, 2002).
The LAM family was the most frequent pattern involved in relapse, which is expected as this family was the most common in the study and it is very common in the study area as well as in Brazil [ 14– 16].
Heterogeneity across samples of previous studies was very common, since several studies comprised mixed samples [ 10, 18, 21, 40, 65] and others showed great differences in illness phase.
