Spatial variance in the 12-lead ECG and mechanical dyssynchrony
Introduction: Electrical transmission disorders have a deleterious effect on cardiac depolarization, resulting in a disorganized ventricular contraction that reduces global mechanical efficiency; this mechanical dyssynchrony ...
Models for multi-environment yield trials with fixed and random block effects and homogeneous and heterogeneous residual variancesModelos para ensayos varietales multiambientales con efectos de bloques fijos y aleatorios y varianzas residuales homogéneas y heterogéneas

Reliability of maximum bite force measurements in age-varying populations
(WILEY-BLACKWELL PUBLISHING, INC, 2009-11-01)
Summary In order for bite forces to be used clinically, they must be reliable. While bite force transducers are accurate and precise during bench tests, widely varying reliabilities of intra-oral bite forces have been ...

Maximum genetic proportion of metric traits from different regions of the skull in ancient humanpopulations of Northwestern Argentina
(Sociedad Española de Anatomía, 2020-09)
In order to explain the evolutionary process of ancient human populations that inhabited a specific geographical region from quantitative skull traits, it is advisable to know the evolutionary potential of metric characters. ...
Effect of missing values on variance component estimates in multienvironment trials
(Crop Science Society of America, 2019-03)
Multienvironment trials (METs) are conducted to evaluate cultivars across locations and years with often incomplete data structure due to annual cultivar replacements. The imbalance could cause biased variance component ...
The Conditional Heterocedasticity on the Argentine Inflation: An Analysis for the Period from 1943 to 2013
(David Publishing, 2017-10)
Numerous economic time series do not have a constant mean and in practical situations, we often see that the variance of observational error is subject to a substantial variability over time. This phenomenon is known as ...
