Two-dimensional electron energy-loss spectra of acrylonitrile are presented in the incident energy range 0.095-0.9 eV, where the incoming electron is temporarily captured in the lowest π* orbital. The cross section is plotted as a function of the incident electron energy that determines which vibrational resonant anion state is populated, and of the electron energy loss, that shows into which f...

We present a program that uses an optimization algorithm to fit rocking curves of ion-implanted semiconductors. This is an inverse problem that cannot be solved by simple methods. However, using recursion formulae for rocking curve calculations and a model of ion distribution after implantation, it is possible to fit experimental data with a general-purpose optimization method. In our case, we ...

We describe a rocking bed for use in incubators. Its effect was studied in 12 preterm infants with idiopathic apnoea, using each as his own control. All but one had less apnoea when the bed was rocking than when it was still. Apnoea associated with a significant fall in transcutaneous PO2 was less frequent, and fewer interventions were needed to terminate apnoeic attacks.

The KiK-net is a vertical array system, and seismic motions are recorded at the ground surface and in the borehole. With the peak acceleration of 24.5 m/s2 at AKTH04 (EW) and 38.7 m/s2 at IWTH25 (UD) during the Iwate–Miyagi Nairiku earthquake in 2008, the occurrence mechanism of large accelerations is investigated by the non-stationary Fourier spectra and the double integrated displacement prof...

We investigated the interwire distance dependence on the growth kinetics of vertical, high-yield InAs nanowire arrays on Si 111 grown by catalyst-free selective area molecular beam epitaxy MBE . Utilizing lithographically defined SiO2 nanomasks on Si 111 with regular hole patterns, catalyst-free and site-selective growth of vertically 111 -oriented InAs nanowires was achieved with very high yie...

In this work, we applied a Bayesian time-lapse (4D) seismic inversion to deep-water heavy oil field located in the Campos Basin (Brazil). procedure, differences of amplitudes baseline and repeated surveys are input calculate changes acoustic impedances. To ensure quality results, parametrization was performed by analyzing anomalies resolution signal-to-noise ratio with different values paramete...

Background: Mixing in traditional algae culture system consumes intensive electricity. This should be replaced by nature force to reduce energy cost and, more importantly, to realize positive energy balance of algal biofuel production. This study aims to develop a horizontal photobioreactor, in which mixing can be provided with rocking movement driven by nature force. Results: Simple boxes were...

In this paper we present several techniques for characterizing longitudinal impedances based on transient measurements of the growth rates and tune shifts of unstable coupled-bunch modes. These techniques are applicable to measurement of both fundamental and higher-order mode impedances and allow characterization of shunt impedances and quality factors of the HOMs. Methods presented here are co...
