Age-stratified Assessment of Brain Volumetric Segmentation on the Indian Population Using Quantitative Magnetic Resonance Imaging.

Background And Purpose: Automated methods for quantifying brain tissue volumes have gained clinical interest for their objective assessment of neurological diseases. This study aimed to establish reference curves for brain volumes and fractions in the Indian population using Synthetic MRI (SyMRI), a quantitative imaging technique providing multiple contrast-weighted images through fast postprocessing.

Methods: The study included a cohort of 314 healthy individuals aged 15-65 years from multiple hospitals/centers across India.

Bias sputtering of granular L1-FePt films with hexagonal boron nitride grain boundaries.

In this paper, we present an experimental study of L1-FePt granular films with crystalline boron nitride (BN) grain boundary materials for heat assisted magnetic recording (HAMR). It is found that application of a RF substrate bias (V = -15 V) yields the formation of hexagonal boron nitride (h-BN) nanosheets in grain boundaries, facilitating the columnar growth of FePt grains during sputtering at high temperatures. The h-BN monolayers conform to the side surfaces of columnar FePt grains, completely encircling individual FePt grains.

Comparison of success rate of BlockBuster versus Fastrach LMA as conduit for blind endotracheal intubation: A prospective randomised trial.

Background And Aims: BlockBuster Laryngeal Mask Airway, a newer supraglottic airway device, is claimed to be an efficient conduit for endotracheal intubation. Intubating laryngeal mask airway (LMA) is an established device for the same. This randomised study was undertaken to evaluate the success rate of blind intubation using either of these LMAs.

All-optical control of ferromagnetic thin films and nanostructures.

The interplay of light and magnetism allowed light to be used as a probe of magnetic materials. Now the focus has shifted to use polarized light to alter or manipulate magnetism. Here, we demonstrate optical control of ferromagnetic materials ranging from magnetic thin films to multilayers and even granular films being explored for ultra-high-density magnetic recording.
