We give an outlook on the future of coherence theory and manybody quantum dynamics as experiments develop in the arena of ultra-cold atoms. Novel results on quantum heating of center-of-mass temperature in evaporative cooling and simulation methods for long-range interactions are obtained, using positive-P phase-space techniques. 1 Coherence theory in the 21st century One recognition of importa...

The use of the femtosecond laser in ophthalmic surgery over the last decade has resulted in the development of innovative procedures. The ultra-short infrared laser pulses of the femtosecond laser can be applied precisely and predictably with minimal collateral tissue damage, making it an ideal tool for highly precise ophthalmic surgery. Flap creation in laser in situ keratomileusis (LASIK) is ...

1. Introduction Two pioneering papers on the 2D (two-dimensional) carbon-based material graphene published in 2004 [1-2] ignited an enormous attention to this material and it did not take long before the electron device community showed interest in graphene [3-5]. Mainly graphene's excellent carrier transport properties have attracted device engineers and led to the expectation that graphene co...

Wide-field fluorescence microscopy is an essential tool in modern cell biology. Unfortunately the image quality of fluorescence microscopes is often significantly degraded due to aberrations that occur under normal imaging conditions. In this article, we examine the use of adaptive optics technology to dynamically correct these problems to achieve close to ideal diffraction limited performance....

Searches for physics beyond the Standard Model of particle physics are performed at accelerators worldwide. Although having poorer detection capabilities and large beam uncertainties, ultra high energy cosmic ray (UHECR) experiments present a unique opportunity to look for new physics far beyond the TeV. Nearly horizontal energetic neutrinos, seeing a large atmospheric target volume and with ne...

In this work we propose an orthogonal pulse waveform for wireless ultra wideband (UWB) transmission. The design is based on an ideal low-pass prototype filter having a windowed sinc impulse response. The frequency response of the prototype filter is transferred to the high frequency region using a specific sign modulator. The UWB pulse waveform comprises of the weighted summation of the left si...

We study solutions of the relativistic hydrodynamical equations, which describe spherical or cylindrical expansion of ideal fluid. We derived approximate solutions involving two arbitrary functions, which describe asymptotic behavior of expanding fireballs in ultra-relativistic limit. In case of a linear equation of state p(ε) = κε − c 1 , (0 < κ < 1) we show that the solution may be represente...

Ionic liquids (ILs) are finding technological applications as chemical reaction media and engineering fluids. Some emerging fields are those of lubrication, surface engineering and nanotechnology. ILs are thermally stable, non-flammable highly polar fluids with negligible volatility, these characteristics make them ideal candidates for new lubricants under severe conditions, were conventional o...

Sistemele de comunicaţii de banda ultralargă (ultra wideband – UWB) se dovedesc a fi sisteme noi şi sigure pentru comunicaţiile fără fir, datorită capacităţii lor de a asigura comunicaţii de putere scăzută, cu rată mare de transmisie pe distanţe scurte, într-un mediu aglomerat în care avem un număr mare de căi multiple de propagare. Vom analiza şi compara performanţele a trei tipuri de receptoa...
