Diamonds and their inclusions are unique probes into the deep Earth, tracking the deep carbon cycle to >800 km. Understanding the mechanisms of carbon mobilization and freezing is a prerequisite for quantifying the fluxes of carbon in the deep Earth. Here we show direct evidence for the formation of diamond by redox reactions involving FeNi sulfides. Transmission Kikuchi Diffraction identifies ...

The purpose of the article is to analyze frameworks for artificial intelligence applications. In particular, effectiveness, time-consumption and resources requirement. Linear regression, random forests k nearest neighbors models were created each framework. learning data a dataset containing informations about diamonds their prices. Each model was designed learn diamonds’ prices then make predi...

The problem of counting numbers of tilings of certain regions has long interested researchers in a variety of disciplines. In recent years, many beautiful results have been obtained related to the enumeration of tilings of particular regions called Aztec diamonds. Problems currently under investigation include counting the tilings of related regions with holes and describing the behavior of ran...

% context {Nano-diamonds are an enticing and enigmatic dust component yet their origin is still unclear. They have been unequivocally detected in only a few astronomical objects, they the most abundant of pre-solar grains, both terms mass number.} %aims {Our goal to derive viable set nano-diamond optical constants properties enable modelling any type astrophysical object where, primarily, local...
