DOI: 10.1007/s10840-021-00999-9
Abstract: Electrical transmission disorders have a deleterious effect on cardiac depolarization, resulting in a disorganized ventricular contraction that reduces global mechanical efficiency; this mechanical dyssynchrony can be corrected by cardiac resynchronization therapy. However, despite adjustments in… read more here.

DOI: 10.1016/j.celrep.2019.08.077
Abstract: Summary Technological advances enable assaying multiplexed spatially resolved RNA and protein expression profiling of individual cells, thereby capturing molecular variations in physiological contexts. While these methods are increasingly accessible, computational approaches for studying the interplay… read more here.

DOI: 10.1038/s41467-019-13365-1
Abstract: Leaf unfolding in temperate forests is driven by spring temperature, but little is known about the spatial variance of that temperature dependency. Here we use in situ leaf unfolding observations for eight deciduous tree species… read more here.

DOI: 10.1080/13658816.2022.2048388
Abstract: Abstract The concept of local variance is used in the literature on image processing, and, to a lesser extent, in spatial analyses of local heterogeneity. Ord and Getis’ local statistic of heterogeneity (LOSH) is used… read more here.

DOI: 10.1111/1365-2745.12696
Abstract: 1.State transitions are changes in ecosystem structure and self-reinforcing feedbacks that are initiated when an exogenous driver variable crosses a threshold. Reversing state transitions is difficult and costly. While some state transitions are relatively rapid,… read more here.

DOI: 10.3390/app9091786
Abstract: Poisson distributions have the characteristic of equality between their variance and mean values. By constructing a calculation model of the temporal variance and spatial variance, the relationship between the variance and mean values of lidar… read more here.
