Reevaluating Links Between Meteorite Impacts and Early Cenozoic Global Warming

open access: yesGeophysical Research Letters, 2022
The Paleocene‐Eocene Thermal Maximum (PETM) and the lower Chron 29n hyperthermal event were recently proposed to have been triggered by the meteorite impacts that formed the Marquez Dome (Texas, USA; 58.3 ± 3.1 Ma) and Boltysh (Ukraine; 65.39 ± 0.14 Ma ...

The Spectrum and Orbit of a Fireball Producing Mesospheric Irregularity and Implications for Meteor Mass Deposition

open access: yesThe Astrophysical Journal, 2023
The physical properties of meteoroids producing meteor plasma non-field-aligned irregularities (NFAI) in the Earth’s atmosphere are poorly known. Here we report a complete picture of a fireball and mesospheric NFAI that it produced for the first time ...

Observation of Vertically Ejected Plumes Generated by the Impact of Hollow Projectiles at Various Velocities

open access: yesThe Planetary Science Journal, 2023
Recently, impact experiments in space have been conducted in planetary exploration using hollow or internally structured projectiles. In laboratory experiments using hollow projectiles to investigate the differences in crater and ejecta from the case of ...

A Single Ejection Model of the DART/Dimorphos Debris Trail

open access: yesThe Astrophysical Journal Letters, 2023
The collision of the NASA DART spacecraft with asteroid Dimorphos resulted in the formation of a distinctive and long-lived debris trail, formed by the action of solar radiation pressure on ejected particles.

Impact of Aging Phenomena on Latches’ Robustness [PDF]

open access: yesIEEE Transactions on Nanotechnology, 2016
In this paper, we analyze the effects of aging mechanisms on the soft error susceptibility of both standard and robust latches. Particularly, we consider bias temperature instability (BTI) affecting both nMOS (positive BTI) and pMOS (negative BTI), which is considered the most critical aging mechanism threatening the reliability of ICs.

Magnetic Field Signatures of Intermediate-sized Impact Craters on Mars

open access: yesThe Astrophysical Journal, 2023
Magnetic field signatures over impact craters provide constraints for the history of the Martian dynamo. Due to limitations of the spatial resolution of magnetic field models, previous studies primarily focused on large impact craters (mostly ≥ 500 km in
