Indirect Ballistic Injury Resulting in Non-ST-Segment Elevation Myocardial Infarction. [PDF]
JACC Case RepGunshot-related myocardial injuries typically result from direct penetrating injury by the traversing bullet. We present a case of gunshot-related myocardial injury in the absence of direct penetrating injury to the cardiac structures and describe alternative mechanisms for ballistic-induced injury.

The effects of temperature and body mass on jump performance of the locust Locusta migratoria. [PDF]
PLoS ONE, 2013 Locusts jump by rapidly releasing energy from cuticular springs built into the hind femur that deform when the femur muscle contracts. This study is the first to examine the effect of temperature on jump energy at each life stage of any orthopteran ...

Signatures of non-local conductivity in near-field microscopy [PDF]
Phys. Rev. B 107, 205409 (2023), 2022 We propose and theoretically substantiate a new method to study the non-local conductivity of two-dimensional electron systems (2DES) using the tools of near-field microscopy. We show that the height dependence of induced dipole moment of illuminated near-field probe is substantially different for various transport regimes of charge carriers in 2DES ...

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 875-889, December 2022., 2022 Effective management of invasive species requires rapid detection and dynamic monitoring. To meet these demands, we applied deep learning neural networks to Worldview‐2 and Planetscope satellite imagery in an effort to detect the invasive plant, leafy spurge (Euphorbia virgata), across a heterogeneous landscape in Minnesota, USA.

Imaging Hydrodynamic Electrons Flowing Without Landauer-Sharvin Resistance [PDF]
, 2021 Electrical resistance usually originates from lattice imperfections. However, even a perfect lattice has a fundamental resistance limit, given by the Landauer conductance caused by a finite number of propagating electron modes. This resistance, shown by Sharvin to appear at the contacts of electronic devices, sets the ultimate conductance limit of non ...

Phonon Engineering of Micro‐ and Nanophononic Crystals and Acoustic Metamaterials: A Review
Small Science, Volume 3, Issue 1, January 2023., 2023 Phononic crystals and acoustic metamaterials with phonon wave manipulation capabilities have attracted considerable attention. This review summarizes the progress and identifies gaps in phonon engineering at the micro‐ and nanoscales using phononic crystals and metamaterials due to their potential significance in modern electronic applications.

Wildlife Society Bulletin, Volume 46, Issue 5, December 2022., 2022 Culling white‐tailed deer populations in oak forests in northwestern Ohio, USA, rapidly reduced browse damage on native tree seedlings and increased cover and species richness of deer‐sensitive plants. Rhizomatous, clonally reproducing species showed the largest increases after deer culling.

A ballistics module as a part of the fire control system
Vojnotehnički Glasnik, 2013 This article presents a ballistics module as a part of the fire control system of weapons for fire support (mortars, artillery weapons and rocket launchers). The software is "open" with the prominence of autonomy work.
