Generation of over 1000 Diffraction Spots from 2D Graded Photonic Super-Crystals (open access)

Generation of over 1000 Diffraction Spots from 2D Graded Photonic Super-Crystals

Discusses a project in which researchers were able to generate over 1000 diffraction spots from a graded photonic super-crystal with a unit super-cell size of 12a × 12a where a is the lattice constant and hole radii are gradually changed in dual directions.

High-Throughput Computational Search for Half-Metallic Oxides (open access)

High-Throughput Computational Search for Half-Metallic Oxides

The article describes a high-throughput computational search for half-metallic compounds. The analysis of calculated electronic properties of thousands of materials from the inorganic crystal structure database allowed the authors to identify potential half metals. They found over two-hundred strong half-metallic oxides; several of them have never been reported before.

Prescriptions for Correcting Ultraviolet-based Redshifts for Luminous Quasars at High Redshift (open access)

Prescriptions for Correcting Ultraviolet-based Redshifts for Luminous Quasars at High Redshift

This article presents near-infrared spectroscopy of 18 luminous quasars at 2.15 < z < 3.70 that allows the authors to obtain reliable systemic redshifts for these sources.

Topological View of Flows Inside the BOLD Spontaneous Activity of the Human Brain (open access)

Topological View of Flows Inside the BOLD Spontaneous Activity of the Human Brain

Article describes study which found that persistent, recurring blood oxygen level dependent (BOLD) signals in triangulated rs-fMRI videoframes display previously undetected topological findings, i.e., vortex structures that cover brain activated regions.
