Finding Asteroids Down the Back of the Couch: A Novel Approach to the Minor Planet Linking Problem [PDF]
arXiv, 2018 We present a novel approach to the minor planet linking problem. Our heliocentric transformation-and-propagation algorithm clusters tracklets at common epochs, allowing for the efficient identification of tracklets that represent the same minor planet.

Understanding the Growth and Properties of Sputter‐Deposited Phase‐Change Superlattice Films
Advanced Materials Interfaces, EarlyView.The study explores the sputter deposition of highly textured chalcogenide superlattice films for phase‐change memory applications. It examines the effects of temperature, pressure, and seeding layer on film growth, constructing a pseudo‐phase diagram to understand the effect of each growth parameter.

Advanced Materials Technologies, EarlyView.In this work, spherical powders of refractory Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W high‐entropy alloys (R‐HEAs) have been fabricated in a single step by plasma‐assisted centrifugal atomization. Loss of the heaviest elements in the composition is observed only at rotational speeds higher than 13 000 rpm due to solid‐solid centrifugal separation.
