We investigate the critical current I_{C} of ballistic Josephson junctions made of encapsulated graphene-boron-nitride heterostructures. We observe a crossover from the short to the long junction regimes as the length of the device increases. In long ballistic junctions, I_{C} is found to scale as ∝exp(-k_{B}T/δE). The extracted energies δE are independent of the carrier density and proportiona...

In the present study the impulse Ib transmitted by a hemispherical contact charge is calculated analytically and compared with experimental measurements. The impulse is measured experimentally with the use of a ballistic pendulum. The explosive charge is placed on a disk shaped striking mass. The mass is in contact with a nondeformable tubular structure placed on an instrumented base on a balli...

We present the first attempt of charge carrier transport modeling in III-nitride multipleQW light-emitting diode structures which takes into consideration ballistic overshoot of the device active region. For the purpose of this study, the drift-diffusion based Transport module of our software package has been complemented by a simple model of ballistic carrier transport which proved to be essen...

The Department of Defense conducts ballistic resistance testing to estimate the probability that a projectile will perforate the armor of a system under test. Ballistic resistance testing routinely employs sensitivity experiment techniques in which sequential test designs are used to estimate armor performance. Statistical procedures used to estimate the ballistic resistance of armor in the DoD...

We have measured mass transport of normal liquid He through an array of submicron diameter apertures in a thin membrane. As the temperature is decreased we observe the crossover from viscous flow to ballistic effusion transport by quasiparticles. In this ballistic regime the quasiparticle mean free path is large compared to both the aperture diameter and the membrane thickness, and the flow con...

With the help of the methods developed in [21], we highlight condition (T ) as a source of new examples of ’ballistic’ diffusions in a random environment when d ≥ 2 (’ballistic’ means that a strong law of large numbers with non-vanishing limiting velocity holds). In particular we are able to treat the case of non-constant diffusion coefficients, a feature that causes problems. Further we recove...

Imaging and reconstruction of developing neurons require cells that are labeled in a way that distinguishes them from their neighbors. This can be achieved with ballistic labeling, which refers to the delivery of a cell label by means of carrier particles (tungsten or gold) propelled from a pressurized gun. Ballistic delivery can reach many dispersed cells in one shot and can deploy a wide vari...

Common movements like reaching, striking, etc. observed during surveillance have highly variable target locations. This puts appearance-based techniques at a disadvantage for modelling and recognizing them. Psychological studies indicate that these actions are ballistic in nature. Their trajectories have simple structures and are determined to a great degree by the starting and ending positions...

Progress in manufacturing technology has allowed us to probe the behavior of devices on a smaller and faster scale than ever before. With increasing miniaturization, quantum effects come to dominate the transport properties of these devices, between collisions, carriers undergo ballistic motion under the influence of local electric and magnetic fields. The often surprising properties of quantum...
