The impact on the nominal power pattern of random and not a-priori known errors affecting the excitation amplitudes of real linear arrays is analyzed by means of an analytic approach based on the interval analysis math. Starting from the expressions of the pattern bounds as a function of the excitation tolerances modeling the saturation in the amplifiers of the array feeding network, the effect...

The fusion evaporation-residue cross sections for 32 S+ 184 W have been mea-246, and 257 MeV using the ATLAS Fragment Mass Analyzer. The data are compared with Statistical Model calculations and it is found that a nuclear dissipation strength, which increases with the excitation energy is required to reproduce the excitation function. A comparison with previously published data shows that the d...

We have implemented simultaneous picosecond pulsed two- and three-photon excitation of near-UV and visible absorbing fluorophores in a scanning near-field optical microscope (SNOM). The 1064-nm emission from a pulsed Nd:YVO4 laser was used to excite the visible mitochondrial specific dye MitoTracker Orange CM-H2TMRos or a Cy3-labeled antibody by two-photon excitation, and the UV absorbing DNA d...

Energy transfer and the primary charge separation process are studied as a function of excitation wavelength in membrane-bound reaction centers of Rhodobacter sphaeroides in which the excitonically coupled bacteriochlorophyll homodimer is converted to a bacteriochlorophyll-bacteriopheophytin heterodimer, denoted D [Bylina, E. J., and Youvan, D. C. (1988) Proc. Natl. Acad. Sci. U.S. A. 85, 7226]...

A torque tracking and parameter identification scheme using a receding horizon optimization is developed for an over-actuated spacecraft Reaction Wheel Array (RWA). Additional actuator motion, constrained to the null-space of the array, is provided in order to enhance persistence of excitation. Therefore, the system parameters are learned without inducing large perturbations to the controllable...

Aims. We study an unknown, or very poorly known, interstellar H  component in the Magellanic Clouds. This is the first study ever devoted to this class of objects, which we call Low-excitation blobs (LEBs). Methods. We used low-dispersion spectroscopy carried out at ESO to obtain emission line intensities of Hα, Hβ, and [O ] (λλ 4959+ 5007) for 15 objects in the Large Magellanic Cloud and ...

The excitation energy and the nuclear density at the time of breakup are extracted for the α + Au reaction at beam energies of 1 and 3.6 GeV/nucleon. These quantities are calculated from the average relative velocity of intermediate mass fragments (IMF) at large correlation angles as a function of the multiplicity of IMFs using a statistical model coupled with many-body Coulomb trajectory calcu...

Resonant vibrational and rotation–vibration excitation cross sections for electron–CO scattering are calculated in the 0–10 eV energy range for all 81 vibrational states of CO, assuming that the excitation occurs via the 2 shape resonance. Static exchange plus polarization calculations performed using the R-matrix method are used to estimate resonance positions and widths as functions of intern...

: We investigate the effects of coupling between a molecular exciton, which consists of an electron and a hole in a molecule, and a surface plasmon (exciton-plasmon coupling) on the electron transitions of the molecule using nonequilibrium Green's function method. Due to the exciton-plasmon coupling, excitation channels of the molecule arise in the energy range lower than the electronic excitat...

In this work, we present an experimental study of dissociative excitation of CH4 utilizing a crossed electron molecular beam experiment. Methane was excited by nearly monochromatic electrons generated by a trochoidal electron monochromator. The dissociative products were identified on the basis of the emission spectra in the ultraviolet–visible (UV/VIS) spectral range. The excitation functions ...
