Adjustment of the electric current in pulsar magnetospheres and origin of subpulse modulation

, 2012
The subpulse modulation of pulsar radio emission goes to prove that the plasma flow in the open field line tube breaks into isolated narrow streams. I propose a model which attributes formation of streams to the process of the electric current adjustment

Additive Processing of Ti‐17 by Wire Arc Directed Energy Deposition: An Investigation of the Microstructure and Mechanical Properties

Advanced Engineering Materials, EarlyView.
This study focuses on processing the titanium alloy Ti‐17 using wire arc directed energy deposition (waDED), with an emphasis on the microstructure and mechanical properties. The waDED typical heat‐affected zone banding is characterized and related to the local mechanical properties.

Optimal Source Tracking and Beaming of LISA [PDF]

, 2006
We revisit the directionally optimal data streams of LISA first introduced in Nayak etal. It was shown that by using appropriate choice of Time delay interferometric (TDI) combinations, a monochromatic fixed source in the barycentric frame can be ...

LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

Advanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

Advanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Kinematically Detected Halo Streams

, 2016
Clues to the origins and evolution of our Galaxy can be found in the kinematics of stars around us. Remnants of accreted satellite galaxies produce over- densities in velocity-space, which can remain coherent for much longer than spatial over-densities ...
