We globally optimize a terawatt-laser-driven wakefield accelerator by systematically varying laser and target parameters to achieve 100 MeV electrons, 10% energy spread, 100 pC charge, 4 mrad divergence and 10 mrad pointing ...

The controversy between the theory and experiment in explaining the origin of enhanced flexoelectricity is removed by taking into account the pseudo Jahn-Teller effect (PJTE) which, under certain conditions, creates local ...

Behind-armor debris that results from tungsten rods penetrating armor steel at 2 km/s was studied by analysis of recovered fragments. Fragment recovery was by means of particle board. Individual fragments were analyzed by ...

The electronic structure and magnetism of Cobalt doped BaTiO3 (BaTi1-xCoxO3) is investigated. Substitutional Nitrogen on an Oxygen site is found to play an important role in inducing net magnetic moments in the system. The ...

Continual scaling of devices and on-chip wiring has brought significant challenges for materials and processes beyond the 32-nm technology node in microelectronics. Recently, three-dimensional (3-D) integration with ...

The eclipsing low-mass X-ray binary 4U 1822-371 is the prototypical accretion disk corona (ADC) system. We have obtained new time-resolved UV spectrograms of 4U 1822-371 with the Hubble Space Telescope and new V- and J-band ...

The effect of line scaling on Cu grain structures has been investigated by using both plan-view and cross-sectional transmission electron microscopy (TEM) techniques. Cu damascene lines with three different line widths of ...

We have investigated the growth of self-assembled InAs quantum dots using bismuth as a surfactant to control the dot size and density. We find that the bismuth surfactant increases the quantum dot density, size, and ...

Electron self-injection into a laser-plasma accelerator (LPA) driven by the Texas Petawatt (TPW) laser is reported at plasma densities 1.7 - 6.2 x 10(17) cm(-3). Energy and charge of the electron beam, ranging from 0.5 GeV ...

A 2-way integral equation coupled mode (IECM) approach is used to examine the physics of scattering from a rough seabed. Roughness realizations for the seabed are generated from a wavenumber power spectrum whose parameterization ...
