Monitoring the Birth of an Electronic Wavepacket in a Neutral Molecule with Attosecond Time-Resolved Photoelectron Spectroscopy

Numerical simulations are presented to validate the possible use of cutting-edge attosecond time- resolved photoelectron spectroscopy to observe in real time the creation of an electronic wavepacket and subsequent electronic motion in a neutral molecule photoexcited by a UV pump pulse within a few femtoseconds

Key Competences in Europe: Opening Doors For Lifelong Learners Across the School Curriculum and Teacher Education

The aim of the study is to provide a comparative overview of policy and practice concerning the development and implementation of key competences in the education systems of the 27 Member States of the European Union. In particular, the study assesses the implementation of the 8 key competences contained in the European Reference Framework of Key Competences in primary and secondary schools across the EU as well as the extent to which initial and in-service education and training of teachers equips them with the skills and competences necessary to deliver key competences effectively.key competences, lifelong learning, cross-curricular, competence

Detecting transcriptionally active regions using genomic tiling arrays

We have developed a method for interpreting genomic tiling array data, implemented as the program TranscriptionDetector. Probed loci expressed above background are identified by combining replicates in a way that makes minimal assumptions about the data. We performed medium-resolution Anopheles gambiae tiling array experiments and found extensive transcription of both coding and non-coding regions. Our method also showed improved detection of transcriptional units when applied to high-density tiling array data for ten human chromosomes

OZONE PHOTOLYSIS: STRONG ISOTOPOLOGUE/ISOTOPOMER SELECTIVITY IN THE STRATOSPHERE

Author Institution: CTMM Institut Charles Gerhardt UMR-CNRS 5253; University of Montpellier, France; Univ. Grenoble 1 / CNRS, LIPhy UMR 5588, Grenoble, F-38041, France; Department of Information Technology, University of Debrecen, P.O. Box 12, H-4010 Debrecen, HungaryUsing the visible-UV absorption cross section (Abs. XS) of five ozone isotopologues and an averaged actinic flux, we have calculated the contribution of the atmospheric ozone photolysis to the oxygen isotope and ozone isotopologue/isotopomer enrichment. Five ozone isotopologues/isotopomers are considered among which three are symmetric, $O^{16}3$ (noted 666), $O^{16}O^{17}O^{16}$ (676) and $O^{16}O^{18}O^{16}$ (686), and two are asymmetric, $O^{17}O^{16}_2$ (667) and $O^{18}O^{16}_2$ (668). The photolysis rates of the five ozone isotopologues have been calculated as a function of altitude. The Multi Configuration Time Dependent Hartree (MCTDH) method and the potential energy surfaces calculates by R. Schinke and {\it coworkers} have been used. We have used experimental actinic fluxes, averaged for latitude and season, for altitudes varying by step of 4km up to 80km. Below ~35km, the contribution of the Hartley band to the photolysis rates is restricted to its low energy range, named the Huggins band, which has strong isotopologue/isotopomer selectivity and then induces strong enrichment. Consequently, the isotopologue enrichment's due to ozone photolysis are strongly dependent of the altitude, with pronounced enrichment peaks around 35 km, the altitude corresponding to the maximum relative contribution of the Huggins band. \vspace{1em} We will also present some new simulations for the simulation of laser-induced quantum dynamics of the electronic and nuclear motion in the ozone molecule on the attosecond time scale. \vspace{1em
