A Late Paleocene age for Greenland's Hiawatha impact structure. [PDF]
Sci Adv, 2022 The ~31-km-wide Hiawatha structure, located beneath Hiawatha Glacier in northwestern Greenland, has been proposed as an impact structure that may have formed after the Pleistocene inception of the Greenland Ice Sheet.

Globally distributed iridium layer preserved within the Chicxulub impact structure. [PDF]
Sci Adv, 2021 The preservation of the iridium-rich layer within the Chicxulub crater captures the timing of the K-Pg boundary events. The Cretaceous-Paleogene (K-Pg) mass extinction is marked globally by elevated concentrations of iridium, emplaced by a hypervelocity ...

Precise radiometric age establishes Yarrabubba, Western Australia, as Earth's oldest recognised meteorite impact structure. [PDF]
Nat Commun, 2020 The ~70 km-diameter Yarrabubba impact structure in Western Australia is regarded as among Earth’s oldest, but has hitherto lacked precise age constraints. Here we present U–Pb ages for impact-driven shock-recrystallised accessory minerals.

Impact of Community Structure on Cascades [PDF]
Proceedings of the 2016 ACM Conference on Economics and Computation, 2020 The threshold model is widely used to study the propagation of opinions and technologies in social networks. In this model, individuals adopt the new behavior based on how many neighbors have already chosen it.

Impact‐Induced Porosity and Microfracturing at the Chicxulub Impact Structure
Journal of Geophysical Research: Planets, 2019 Porosity and its distribution in impact craters has an important effect on the petrophysical properties of impactites: seismic wave speeds and reflectivity, rock permeability, strength, and density.

Stress and Displacement of Cylindrical Lithium-Ion Power Battery during Charging and Discharging
Energies, 2022 During the charging and discharging process of a lithium-ion power battery, the intercalation and deintercalation of lithium-ion can cause volume change in the jellyroll and internal stress change in batteries as well, which may lead to battery failures ...

Effect of Deformation on Safety and Capacity of Li-Ion Batteries
Batteries, 2022 Deformations in lithium-ion batteries, which may lead to thermal runaway, can occur during storage and transportation handling, as well as in road use. In this study, both radial and axial compression deformation were produced experimentally to analyze ...
