We consider an energy harvesting transmitter equipped with two batteries having finite storage capacities, communicating over an additive white Gaussian channel. The work is motivated by an observation that many practical batteries, when repeatedly charged after being partially discharged, suffer from degradation in the usable capacity. The capacity can be recovered by completely discharging th...

Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequencybroadened ‘white-light’ slowing and observe approximately ́ 6 104 CaF molecules in a single pulse with velocities 10 ± 4 m s. CaF is a candidate for collisional studies in the mK regime. This work represents a signifi...

S20 photocathodes have been grown by solid-source molecular-beam deposition (MBD). The unactivated absorbing layer exhibits a maximum response of 29 mA/W at 430 nm while the photocathode shows a sensitivity and a quantum efficiency of 74 mA/W and 22% at 430 nm. This corresponds to a white sensitivity of 200 mA/lm which is already comparable to commercial S20 photocathodes. In addition, the MBD ...

before inner-volume saturation (IVS), up-/downfield inversion for the metabolite cycling, and PRESS localization. They consist of a two dimensional selective excitation pulse exciting a pencil beam (r=30mm, l=120mm). Figure 1: Sagittal and axial T2 weighted turbo spinecho images of the cervical spinal cord showing the MRS voxel (red), the navigator (white), the innervolume saturation bands (blu...

We present a new method for multi-component power spectra estimation in multifrequency observations of the CMB. Our method is based on matching the cross and auto power spectra of observation maps to their expected values. All the component power spectra are estimated, as well as their mixing matrix. Noise power spectra are also estimated. The method has been applied to full-sky Planck simulati...

The authors report on a rubidium atomic magnetometer designed for use in a shielded environment. Operating in the spin-exchange relaxation-free regime, the magnetometer utilizes parametric modulation of the z-magnetic field to suppress noise associated with airflow through the oven and to simultaneously detect x- and y-field components, using a single probe beam, with minimal loss of sensitivit...

We analytically demonstrate the existence of white light solitons in logarithmically saturable noninstantaneous nonlinear media. This incoherent soliton has elliptic Gaussian intensity profile, and elliptic Gaussian spatial correlation statistics. The existence curve of the soliton connects the strength of the nonlinearity, the spatial correlation distance as a function of frequency, and the ch...

We report on the experimental and theoretical investigation of polarization conversion of linearly polarized Gaussian beam propagating in perpendicularly cut homogeneous uniaxial crystals. We derive analytical expressions, in good agreement with experimental data, for power transfer between components at normal incidence accompanied by the generation of a topological quadrupole. We extend the r...

To visualize the grain boundary role on the shape memory property of Cu-Zn-A1 alloy, we have followed the austenitic structure evolution, of crystals submitted to a training treatment, by synchrotron X-ray topography in white beam. Single crystals, tricrystals and polycrystalline samples have been studied. The comparison of results shows that in polycrystalline samples large, non recoverable st...

For the additive white Gaussian noise channel with average power constraint, sparse superposition codes, proposed by Barron and Joseph in 2010, achieve the capacity. While the codewords of the original sparse superposition codes are made with a dictionary matrix drawn from a Gaussian distribution, we consider the case that it is drawn from a Bernoulli distribution. We show an improved upper bou...
