A geometric algebra approach to coincidence site lattices

Abstract When a lattice in Rn is superimposed on a rotated copy with coincident origins, coincidence points may arise for specific rotations, forming a coincidence site lattice (CSL). In crystallography, particularly in two and three dimensions, CSL theory is fundamental for desc...

Close relationship and role of fractal dimension, heterogeneous nucleation, dynamic transformations and cooperativity mechanisms in unperturbed tumor growth

<title>Abstract</title> The cancer is the second leading cause of death worldwide and remains an enigma for researchers and medical doctors. The aim of this study is to propose a novel methodology that demonstrates the close relationship and role of fractal dimension, heterogeneo...

Contrasting eruptive dynamics and hazards of two Holocene andesitic sub-Plinian to Plinian eruptions, Lower and Upper Citlaltépetl, at Pico de Orizaba, Mexico

Abstract Pico de Orizaba (Citlaltépetl) stratovolcano, eastern Mexico, preserves a complex Holocene explosive record, yet the eruptive dynamics, source parameters, styles, and hazard implications of individual eruptive episodes remain poorly constrained. Here, we examine the 9600...
