From enhanced diffusion to ultrafast ballistic motion of hybrid light–matter excitations
Nature Materials, 2022The authors study ultrafast spatiotemporal dynamics of polaritons formed by mixing surface-bound optical waves with excitons observing a mobility transition from diffusive to ballistic transport flow at two-thirds the speed of light.

Potential of Natural Fibers in Composites for Ballistic Applications – A Review
Journal of Natural Fibers, 2020In this paper, a review of natural fibers composites used in protective armors for ballistic applications like bulletproof vests is presented. It seeks to compile the results and establish natural fiber composites as an alternative to absolute synthetic ...

Annals of Emergency Medicine, 1986
Wound profiles made under controlled conditions in the wound ballistics laboratory at the Letterman Army Institute of Research showed the location along their tissue path at which projectiles cause tissue disruption and the type of disruption (crush from direct contact with the projectile or stretch from temporary cavitation).

Modeling and simulation of impact behavior of 3D woven solid structure for ballistic application
Journal of Industrial Textiles, 2020This study was carried out to understand and evaluate the response of 3 D woven fabrics upon the simulated ballistic forces. Under the low-velocity impact, analytical and numerical models were developed for determining the impact energy, which was used ...

Understanding Ballistic Injuries
Radiologic Clinics of North America, 2023Understanding the pathophysiology of a disease allows physicians to make a diagnosis, alter its natural course, and develop and implement appropriate preventative and management strategies. With ballistic injuries, an understanding of how the mechanism of injury translates to the injuries observed makes it possible to make sense of what can, at times ...

Thermal Spreading Resistance in Ballistic-Diffusive Regime for GaN HEMTs
IEEE Transactions on Electron Devices, 2019To develop an efficient thermal design for gallium-nitride (GaN) high-electron-mobility transistors (HEMTs) that usually hold a super-high-power density, it is essential to accurately predict the junction temperature.

Canadian Association of Radiologists Journal, 2020
Here in Canada, we often think of gun violence as confined to conflict zones, terrorism, and more of a problem for our southern neighbor. However, in recent years, it has also become a Canadian problem with increased gun violence related to criminal activity presenting in daily practice. Radiologists play a critical role in the evaluation of ballistic

Ballistic performance of multi-metal systems
, 2020Ballistic resistance enhancement of armours and structures has been a prominent area of research over the years. Monolithic metallic plates have been the preferred choice for armours against high-velocity projectiles.

Physical Review E, 1996
We introduce and investigate the scaling properties of a random walker that moves ballistically on a two-dimensional square lattice. The walker is scattered (changes direction randomly) every time it reaches a previously unvisited site, and follows ballistic trajectories between two scattering events.

Ballistic Trauma: Overview and Statistics – Wound Ballistics
2016Wound ballistics is the specialty in ballistics dealing with the interaction of bullet and tissue, resulting in lesions when humans or animals are hit. The lesions depend on the velocity and mass of the bullet as well as its design. Bullets are divided into low- and high-velocity bullets.
