Influence of cryogenic treatment on mechanical and ballistic properties of AA5754 alloy friction stir welded joints

Defence Technology
In the present study, the mechanical and ballistic properties of friction stir welded (FSW) aluminum alloy (AA5754) samples were investigated, both untreated and cryogenically treated, when impacted by a 7.62 mm armour-piercing (AP) bullet at an impact ...

Coulomb entangler and entanglement testing network for waveguide qubits

, 2005
We present a small network for the testing of the entanglement of two ballistic electron waveguide qubits. The network produces different output conditional on the presence or absence of entanglement.

Conditions for Adiabatic Spin Transport in Disordered Systems [PDF]

, 2003
We address the controversy concerning the necessary conditions for the observation of Berry phases in disordered mesoscopic conductors. For this purpose we calculate the spin-dependent conductance of disordered two-dimensional structures in the presence ...

Impact of particles on the Planck HFI detectors: Ground-based measurements and physical interpretation [PDF]

, 2014
The Planck High Frequency Instrument (HFI) surveyed the sky continuously from August 2009 to January 2012. Its noise and sensitivity performance were excellent, but the rate of cosmic ray impacts on the HFI detectors was unexpectedly high.
