Tokamaks with weak to moderate reversed central shear in which the minimum rotational transform

q_{min}

is in the neighbourhood of unity can trigger bifurcated MagnetoHydrodynamic (MHD) equilibrium states, one of which is similar to a saturated ideal ...

Increased Speed: 3D Silicon Sensors; Fast Current Amplifiers

Matthieu Despeisse

The authors describe techniques to make fast, sub-nanosecond time resolution solid-state detector systems using sensors with 3D electrodes, current amplifiers, constant-fraction comparators or fast wave-form recorders, and some of the next steps to reach s ...

Models of non-relativistic quantum gravity: the good, the bad and the healthy

Sergey Sibiryakov, Diego Blas Temino

Horava's proposal for non-relativistic quantum gravity introduces a preferred time foliation of space-time which violates the local Lorentz invariance. The foliation is encoded in a dynamical scalar field which we call 'khronon'. The dynamics of the khrono ...

One-loop adjoint masses for non-supersymmetric intersecting branes

Alessandro Vichi

We consider breaking of supersymmetry in intersecting D-brane configurations by slight deviation of the angles from their supersymmetric values. We compute the masses generated by radiative corrections for the ad joint scalars on the brane world-volumes. I ...

Emergency Vehicle Prioritization using Vehicle-To-Vehicle Communication

Emergency vehicles need to reach their destination as fast as possible. They deserve the highest priority at intersections. Therefore, they are allowed to use bus lanes and pass red lights at traffic light systems. Nevertheless, for emergency vehicles it i ...

Drift Stabilisation of Ballooning Modes in an Inward-Shifted LHD Configuration

Jonathan Graves, Wilfred Anthony Cooper, Lucie Brocher

A drift-magnetohydrodynamic theory is applied to a background anisotropic pressure equilibrium state to generate a drift corrected ballooning mode equation. The ratio of the mode frequency to the hot particle drift frequency constitutes the critical expans ...

Robust Ultrasound Travel-time Tomography Using the Bent Ray Model

Martin Vetterli, Olivier Roy, Ali Hormati, Ivana Jovanovic

We present a bent ray reconstruction algorithm for an ultrasound tomography (UT) scanner designed for breast screening. The scanner consists of a circular array of transmitters and receivers which encloses the object to be imaged. By solving a nonlinear sy ...

Energy's and amplitudes' positivity

Riccardo Rattazzi

In QFT, the null energy condition (NEC) for a classical field configuration is usually associated with that configuration's stability against small perturbations, and with the sub-luminality of these. Here, we exhibit an effective field theory that allows ...

TURN SPECIFIC VS. LINK BASED TRAVEL TIMES CALCULATED FROM FLOATING CAR DATA

Floating car data (FCD) meanwhile is a widely available and affordable data source. The given GPS data – delivered in frequencies of some seconds or sometimes only a few minutes – are typically matched to some digital road network and mainly the traffic va ...
