In this study we report about the investigation of the spectral region 1.22-1.32 µm of the night side of Venus, observed by the VIRTIS instrument (Visible and InfraRed Spectral Imaging Spectrometer) on board the Venus Express spacecraft. This spectral region is characterized by the presence of the extensively studied (a1Δg – X3Σg-) (0,0) O2 nightglow band, the most intense emission observed on the night side of Venus. However, the comparison between data and synthetic spectra from the (0,0) band only, lacks a good match at wavelengths longer than 1.27 μm, especially in the region around 1.28-1.29 μm. The effects of temperature, CO2 and the (8,5) OH emission at 1.28 µm were investigated as a possible cause to the spectral disagreement, but they all are not enough to explain the observed difference. Instrumental effects were also excluded as possible cause of the mismatch. We found that the inclusion of the (1,1) band O2 emission in the synthetic spectra, originating from the upper vibrational level ν=1 of the (a1Δg – X3Σg-) transition centered at 1.28 μm, in addition to the (0,0), significantly improves the agreement between simulated spectra and observed data in the region at 1.28-1.29 μm. A synthetic spectrum, including the (0,0) and the (1,1) is produced and compared to 4 observed VIRTIS spectra, as an example. From the analyzed data, it results that the (1,1) band with an intensity ranging from the 8 to 15% of the (0,0) band is required to best reproduce the observed VIRTIS spectra. This corresponds to a (1,1) band intensity equal to 3.1-5.8 MR, in limb view, in agreement with the upper limit set by Connes et al., (1979), on their ground-based observations of the oxygen nightglow of Venus.

Convergence analysis of consensus algorithms is revisited in the light of the Hilbert distance. The Lyapunov function used in the early analysis by Tsitsiklis is shown to be the Hilbert distance to consensus in log coordinates. Birkhoff theorem, which proves contraction of the Hilbert metric for any positive homogeneous monotone map, provides an early yet general convergence result for consensus algorithms. Because Birkhoff theorem holds in arbitrary cones, we extend consensus algorithms to the cone of positive definite matrices. The proposed generalization finds applications in the convergence analysis of quantum stochastic maps, which are a generalization of stochastic maps to non-commutative probability spaces. [less ▲]

This paper proposes simple feedback loops, inspired from extremum-seeking, that use the photon emission times of a single quantum system following quantum Monte-Carlo trajectories in order to lock in real time a probe frequency to the system’s transition frequency. Two specific settings are addressed: a 3-level system coupling one ground to two excited states (one highly unstable and one metastable) and a 3-level system coupling one excited to two ground states (both metastable). Analytical proofs and simulations show the accurate and robust convergence of probe frequency to system-transition frequency in the two cases. [less ▲]

Background: Human cytomegalovirus (HCMV) has established itself as the most significant cause of congenital infection in the developed world. The objective of this research was prenatal identification of pregnant women at risk for developing active infection due to HCMV as well as to diagnose congenitally infected newborns. Methods: A diagnostic algorithm based on specific immunoglobulin G (IgG), IgM, and, IgG avidity was used to screen serum from 1131 pregnant women enrolled prospectively from 3 municipalities from Havana City, Cuba during 2007–2008. Qualitative multiplex nested PCR and quantitative real time-based PCR testing for HCMV DNA were performed on urine and saliva specimens from women detected with active infection and from their newborns. Results: Most women were seropositive to HCMV (92.7%), with 2.38% (27 women) having active infection. Primary infection was detected in 20 pregnant women (1.77%) while 7 patients (0.62%) had active nonprimary infection. HCMV DNA was detected in specimens from 9 of the 27 pregnant women by both PCR methods. HCMV congenital infection was diagnosed in 12 (1.06%) of the 26 live children born from 25 mothers with active infection, for a vertical transmission rate of 46.2%. Two fetal deaths were reported from 2 women with active infection; furthermore 2 newborns were symptomatic at birth and 2 showed sequelae during the follow-up done until 6 months age. Conclusions: Mothers with active infection during the pregnancy and with HCMV excretion had significant risks, RR = 1.16 and RR = 1.35, respectively, to have congenitally infected children. [less ▲]

We studied the identification of key habitat parameters for two specialist woodpecker species (middle spotted woodpecker Dendrocopos medius and lesser spotted woodpecker D. minor) associated with mature broadleaved forests ecosystems in Europe, and the modelling of their specific requirements with a view to assist forest managers. The study was conducted in four beech and oak-dominated forests (Haut-Fays, Halma, Gembes and Croix-Scaille) located in the Ardennes Region of Southern Belgium. The study sites covered a total area of ca. 20 km². A census of woodpecker occurrence (presenceabsence) was implemented from 2000 to 2003 within 255 1-ha plots. Habitat variables describing stand age, tree density, snag density, stand composition and vertical vegetation structure were also sampled at the same plots to develop both logistic and autologistic regression models describing habitat use.Middle spotted woodpecker (MSW) uses the oak-rich locations (mean basal area of 15.6 m²/ha), with selection of areas with the largest, oldest oak trees (mean circumference > 150 cm), and with a high diversity of tree species in the overstory. Similarly, the lesser spotted woodpecker (LSW) was detected in areas presenting the highest percentage cover of oak trees but with a selection of younger stands, with a high density of snags and dead wood (mean of 9 m³/ha). The integration of an autocorrelation term improved model performance for the LSW but not for MSW. Our results highlight the importance of a high disponibility of oak trees for these two sympatric species. The climax forest in northwest Europe is beech so that public and private owners must develop appropriate forest management plans to prevent the conversion of oak to beech forests. In particular, forest managers can promote an active oakregeneration management to obtain a balanced representation of age classes. They must also aim to maintain/increase the volume of dead wood resources by reserving all trees produced by storms or any other cause of natural mortality. [less ▲]

La population nicheuse de balbuzards pêcheurs en région Centre, principalement établie en forêt d'Orléans et en Sologne, a fait l'objet d'une prémière étude sur le choix des proies et la stratégie alimentaire. L'analyse a été menée sur un échantillon d'une quinzaine de couples. Les premiers résultats montrent que les rapaces consomment une large gamme de poissons, évaluéenà plus de 20 espèces. Quels que soient la méthode utilisée et le nid étudié, ce sont les cyprinidés qui constituent la grande majorité des proies. En période d'étiage, les espèces de poisson de fond viennent également enrichir le régime alimentaire en raison de la faible profondeur de l'eau. [less ▲]
