In this document we illustrate the module preservation statistics on simulated data. We describe the simulation method and seven simulation studies in more detail than in the main text. The design and main results of the simulations are summarized in Figure 8 of the main article which we reproduce here for convenience in Figure 1. A complete table of results can be found in the accompanying Sup...
OBJECTIVES We aimed to validate a new flow convergence (FC) method that eliminated the need to locate the regurgitant orifice and that could be performed semiautomatedly. BACKGROUND Complex and time-consuming features of previously validated color Doppler methods for determining mitral regurgitant volume (MRV) have prevented their widespread clinical use. METHODS Thirty-nine different hemod...

Amphibolitic rocks are the main part of the north of Khoy metamorphic complex. Petrographicaly these rocks are normal amphibolite, muscovite amphibolite, biotite amphibolite, garnet amphibolite and pyroxene amphibolite. The protolith of these rocks is mainly igneous. These rocks belong to tholeiitic and calc-alkaline series and Ocean Floor Basalt and Arc tectonic setting. These two distinctive ...
The Etive igneous complex has intruded into Dalradian and Moine meta-sedimentary rocks in Devonian. Main rock types of the complex are granodiorite, monzodiorite, monzogranite, granite and diorite. Geochemical studies show that the magmas were of high K calc-alkaline, I-type and metaluminous nature. Application of discriminant diagrams to the Etive rocks indicates a possible within-plate tecton...
Mehrabad bentonite deposit appears to be derived from the volcano- sedimentary materials of Oligo-Miocene age by transformation in a lagoon environment. Based on analysis, bentonite samples contain minerals such as montmorillonite, albite, clinoptilolite, quartz, cristobalite, calcite, gypsum, halite, muscovite and nantronite. Conversion of shard glasses to bentonite and zeolite has occurred un...
