The capacity of oceanic crust to record geomagnetic polarity reversals makes sea-surface magnetic anomalies an essential tool study plate tectonics. are usually well-defined at magmatic spreading centers, but distorted and eventually disappear on magma-poor mid-ocean ridges such as the ultraslow Southwest Indian Ridge (SWIR), making their interpretation difficult. We attribute variability SWIR ...

Abstract A global study of subduction zone dynamics indicates that the thermal structure overriding plate may control arc location. fast convergence rate and a steep slab dip bring hotter mantle further into wedge corner, forming volcanoes closer to trench. Separately, laboratory numerical experiments showed development back‐arc spreading center (BASC) is driven by migration subducting hinge, e...

background : due to the crucial role of dental solid waste in the spreading of pathogens and threats to human health and the environment, its optimal management is very important. methods: this was a descriptive cross-sectional study. the study population consisted of 40 dental centers, from among which 11 dental centers were selected through random sampling. from each center, 3 samples were co...

[1] Abyssal-hill shape and orientation are related to the direction and spreading rate of paleo-spreading centers. Therefore analyzing abyssal-hill shape and trend is useful for constraining tectonic models of regions devoid of magnetic reversal anomalies. Detecting systematic changes of abyssal-hill shapes or trends, due to changes in spreading rate or direction, is not straightforward, which ...

Cultural competition has throughout our history shaped and reshaped the geography of boundaries between humans. Language and culture are intimately connected and linguists often use distinctive keywords to quantify the dynamics of information spreading in societies harboring strong culture centers. One prominent example, which is addressed here, is Kyoto's historical impact on Japanese culture....

Epithelial-to-mesenchymal transition (EMT) is a process by which cancer cells gain the ability to leave the primary tumor site and invade surrounding tissues. These metastatic cancer cells can further increase their plasticity by adopting an amoeboid-like morphology, by undergoing mesenchymal-to-amoeboid transition (MAT). We found that adhering cells produce spreading initiation centers (SICs),...
