Intermediate regimes in granular Brownian motion: Superdiffusion and subdiffusion
, 2012 Brownian motion in a granular gas in a homogeneous cooling state is studied theoretically and by means of molecular dynamics. We use the simplest first-principle model for the impact-velocity dependent restitution coefficient, as it follows for the model

Experimental verification of numerical simulation of projectile impact on ballistic shields
Archive of Mechanical Engineering, 2013 Abstract In this work, the author presents experimental verification of numerical simulation of projectile impact on constructional shields. The experimental tests were performed at a unified test stand to investigate ballistic resistance of materials in field conditions.

How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition
Wildlife Biology, EarlyView.Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Conservation Laws and Thermodynamic Efficiencies
, 2013 We show that generic systems with a single relevant conserved quantity reach the Carnot efficiency in the thermodynamic limit. Such a general result is illustrated by means of a diatomic chain of hard-point elastically colliding particles where the total

Journal of Forensic Sciences, EarlyView.Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Mechanical Behavior of FV535 Steel against Ballistic Impact at High temperatures [PDF]
, 2010 This paper presents the results of a wide experimental of ballistic tests against FV535 plates at temperatures from room to 700ºC. Those tests have been done using a light gas gun shooting round balls up to 800m/s.

Shot noise suppression in quasi one-dimensional Field Effect Transistors
, 2009 We present a novel method for the evaluation of shot noise in quasi one-dimensional field-effect transistors, such as those based on carbon nanotubes and silicon nanowires.

Adaptive Optical Layers: Efficient Tall Cell Grids for Liquid Simulation
Computer Graphics Forum, EarlyView.Abstract Tall cell grids have been proposed as an efficient approach to accelerate large‐scale liquid simulation. In this framework, regions near the liquid surface are discretized with regular grids, while regions farther away are represented by elongated rectangular cells.

Experimental Physiology, EarlyView.Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...
