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 ...

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.

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 ...
