Evaluation of the Vibration Signal during Milling Vertical Thin-Walled Structures from Aerospace Materials (open access)

Evaluation of the Vibration Signal during Milling Vertical Thin-Walled Structures from Aerospace Materials

Article describes how the main functions of thin-walled structures are to reduce the weight of the finished product and to increase the rigidity of the structure. The authors compared the vibration signal for different approaches to machining thin walled-components with vertical walls made of Ti6AI4V titanium alloy and Inconel 625 nickel alloy.

Tracing the accretion history of supermassive black holes through X-ray variability: results from the Chandra Deep Field-South (open access)

Tracing the accretion history of supermassive black holes through X-ray variability: results from the Chandra Deep Field-South

This article studies the X-ray variability properties of distant active galactic nuclei (AGNs) in the Chandra Deep Field-South region over 17 yr, up to z ~ 4, and compare them with those predicted by models based on local samples.

Stromatolites: why do we care? (open access)

Stromatolites: why do we care?

Article discussing stromatolites. The authors apply the method of Diffusion Entropy (DE) to the study of stromatolites by means of a two-dimensional procedure that makes it possible for us to compare the DE analysis to the results of a compression method.
