We investigate directed motion in non-adiabatically rocked ratchet systems sustaining few bands below the barrier. Upon restricting the dynamics to the lowest M bands, the total system-plus-bath Hamiltonian is mapped onto a discrete tight-binding model ...

Son of X–Shooter: a multi–band instrument for a multi–band universe [PDF]
Son Of X-Shooter (SOXS) will be a new instrument designed to be mounted at the Nasmyth–A focus of the ESO 3.5 m New Technology Telescope in La Silla site (Chile). SOXS is composed of two high-efficiency spectrographs with a resolution slit product 4500, working in the visible (350 - 850 nm) and NIR (800 - 2000 nm) range respectively, and a light imager

A useful extension to SWIFT (SWeep Imaging with Fourier Transformation) utilizing sidebands of the excitation pulse is introduced. This MRI method, called Multi-Band-SWIFT, achieves much higher bandwidth than standard SWIFT by using multiple segmented excitations (bands) of the field of view.

Multi-band modelling of appearance [PDF]
Earlier work has demonstrated generative models capable of synthesising near photo-realistic grey-scale images of objects. These models have been augmented with colour information, and recently with edge information. This paper extends the active appearance model framework by modelling the appearance of both derived feature bands and an intensity band.

Asynchrony in multi-band speech recognition [PDF]
In this paper, an algorithm for continuous speech recognition systems based on the Multi-Band principle is proposed. This algorithm allows the bands to be asynchronous and has a practical complexity that is very close to the complexity of the classical Viterbi algorithm.

THE MULTI-BAND EMISSION PROFILE IN GRB [PDF]
Gamma-ray burst (GRB) light curves generally are energy dependent, i.e., the higher the photon energy, the narrower the pulse. In addition, the peak of the pulse at lower energies is usually delayed compared with that in higher energy. The phenomenon even exists in some X-ray flares and following optical flares.

Multi-band OFDM for optical networking [PDF]
In this paper, we present a novel networking technique based on optical Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM). We highlight the interesting features of the solution with respect to existing ones (fully opaque optical networks and transparent networks) for optical metro and core networks.

Multi–Band Programmable Gain Raman Amplifier [PDF]
Optical communication systems, operating in C-band, are reaching their theoretically achievable capacity limits. An attractive and economically viable solution to satisfy the future data rate demands is to employ the transmission across the full low-loss spectrum encompassing O, E, S, C and L band of the single mode fibers (SMF).

Bayesian Fusion of Multi-Band Images [PDF]
In this paper, a Bayesian fusion technique for remotely sensed multi-band images is presented. The observed images are related to the high spectral and high spatial resolution image to be recovered through physical degradations, e.g., spatial and spectral blurring and/or subsampling defined by the sensor characteristics.

Holographic multi-band superconductor
We propose a gravity dual for the holographic superconductor with multi-band carriers. Moreover, the currents of these carriers are unified under a global flavored SO(3) symmetry, which is dual to the bulk SO(3) gauge symmetry. We study the phase diagram of our model, and find it qualitatively agrees with the one for the realistic 2-band superconductor,
