The Hilbert transform is one of the most successful approaches to tracking the varying nature of vibration of a large class of nonlinear systems thanks to the extraction of backbone curves from experimental data. Because signals with multiple frequency components do not admit a well-behaved Hilbert transform, it is inherently limited to the analysis of single-degree-of-freedom systems. In this study, the joint application of the complexification-averaging method and the empirical mode decomposition enables us to develop a new technique, the slow-flow model identification method. Through numerical and experimental applications, we demonstrate that the proposed method is adequate for characterizing and identifying multi-degree-offreedom nonlinear systems. [less ▲]

We have investigated the hypothesis that pyrimidine dinucleotides are avoided in light-exposed genomes as the result of selective pressure due to high ultraviolet (UV) exposure. The main damage to DNA produced by UV radiation is known to be the formation of pyrimidine photoproducts: it is estimated that about 10 dimers per minute are formed in an Escherichia coli chromosome exposed to the UV light in direct overhead sunlight at sea level. It is also known that on an E. coli chromosome exposed to UVb wavelengths (290-320 nm), pyrimidine photoproducts are formed in the following proportions: 59 TpT, 7 CpC, and 34 CpT plus TpC. We have analyzed all available complete prokaryotic genomes and the model organism Prochlorococcus marinus and have found that pyrimidine dinucleotides are not systematically avoided. This suggests that prokaryotes must have sufficiently effective protection and repair systems for UV exposure to not affect their dinucleotide composition. [less ▲]

Poly(epsilon-caprolactone) foams were prepared, via a batch process, by using supercritical CO(2) as foaming agent. Their porous structure was characterized through helium and mercury pycnometry, scanning electron microscopy (SEM) and X-ray microtomography observations coupled with image analysis. The pore size distributions obtained by these two latter techniques show that the pore structure is more homogeneous when the foaming process is performed under a high CO(2) saturation pressure (higher than 250 bars).

The Venus airglow has been observed from spectrometers on board rockets probes and satellites such as OUVS on Pioneer Venus Venera Galileo HUT on the Space Shuttle and quite recently SPICAV on Venus Express The spectrum is dominated by emissions from helium hydrogen oxygen and carbon lines and CO bands Localized emissions of OI at 1304 and 1356 A have been sporadically observed on the nightside and are likely caused by precipitation of auroral electrons in the wake of the planet We have developed a Monte Carlo code solving the Boltzmann equation for energetic electrons to calculate the energy distribution function and fluxes of primary and secondary auroral electrons and for photoelectrons The model is used to calculate the vertical distribution of the excitation rate of various excited states For optically thick transitions such as the 3P-3S triplet at 1304 A a radiative transfert code is used to calculate the emergent emission rate We find that the relative intensity of the oxygen and CO Cameron band emissions is a sensitive indicator of the energy of auroral electrons The observed values indicate that the mean energy is on the order of 10-50 eV Dayglow intensity and distributions are also compared with observed characteristics [less ▲]
