Problem of the reference height of the projectile trajectory as a reduced meteo-ballistic weighting factor

Defence Technology, 2014
This paper deals with the issue of preparation of the aiming angles with the use of tabular firing tables and needed determination of the ballistic elements μB (ballistic wind wB, wxB, wZB, ballistic (virtual) temperature τB, ballistic density ρB) from ...

Analytical model of 1D Carbon-based Schottky-Barrier Transistors [PDF]

, 2009
Nanotransistors typically operate in far-from-equilibrium (FFE) conditions, that cannot be described neither by drift-diffusion, nor by purely ballistic models.

Direct observation of shift and ballistic photovoltaic currents

Science Advances, 2019
Shift and ballistic photovoltaic currents, previously indistinguishable experimentally, can now be separated. The quantum phenomenon of shift photovoltaic current was predicted decades ago, but this effect was never observed directly because shift and ...

Mechanical analysis of helmeted headforms under ballistic impact with implications in performance evaluation of ballistic helmets

Frontiers in Mechanical Engineering, 2023
Behind helmet blunt trauma is a significant health concern in modern warfare. The ballistic response of the human head under ballistic impact is highly sought. Towards this end, we conducted ballistic experiments on three different headforms.

Initial Distance‐Dependent Mean Force Drives Synaptic Vesicle Motion Toward Fusion Sites in Stimulated Hippocampal Neurons

Advanced Science, EarlyView.
Synaptic vesicle (SV) motion and exocytosis dynamics in the presynaptic terminals of live neurons are intimately linked to synaptic transmission during neuronal activity. In this work, it is revealed that, during electrical stimulation, SVs located farther from their fusion sites exhibit greater straightness and experience larger mean forces directed ...

Programmable Nanoscale Motion via Molecular Patterning on DNA Origami

Angewandte Chemie, EarlyView.
DNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.

Ballistic and hydrodynamic magnetotransport in narrow channels [PDF]

Physical review B, 2019
An increasing number of low carrier density materials exhibit a surprisingly large transport mean free path due to inefficient momentum relaxation. Consequently, charge transport in these systems is markedly non-ohmic but rather ballistic or hydrodynamic,
