Coherent master equation for laser modelocking

2020

Modelocked lasers constitute the fundamental source of optically-coherent ultrashort-pulsed radiation, with huge impact in science and technology. Their modeling largely rests on the master equation (ME) approach introduced in 1975 by Hermann A. Haus. However, that description fails when the medium dynamics is fast and, ultimately, when light-matter quantum coherence is relevant. Here we set a rigorous and general ME framework, the coherent ME (CME), that overcomes both limitations. The CME predicts strong deviations from Haus ME, which we substantiate through an amplitude-modulated semiconductor laser experiment. Accounting for coherent effects, like the Risken-Nummedal-Graham-Haken multim…

Factors determining pedagogic efficiency of secondary: school critical analysis of academic failure in Burkina Faso

2007

The increase in the rate of school counter-performance raises nowadays, the necessity to apprehend the mechanisms from which this failure stems and is cared for. The collected data revealed the content and worrying side of the academic failure at secondary schools level. The econometric tests have allowed identifying the fundamental role of social background and the initial stage through the type of institution as an explanation to the mass failure, the feeble congruency between the different evaluations during the schooling process, as well as the inefficiency of the school organization through the training of the primary school leavers and the management of secondary schools. Finally, sch…

Engineering 3D ordered molecular thin films by a nanoscale control

2010

This perspective aims to report on experimental preparation and investigation tools for engineering molecular thin films with a three-dimensional (3D) nanoscale control that is of relevant interest for different emerging applications as well as for the development of calibration standards. Such thin films may be obtained by man-made methods, self-assembly or spatio-temporal self-organization and/or by the combination of these last approaches with external tools. Understanding the main features and the physical-chemistry underlying the related ordering phenomena is in due course and a theoretical framework is under development. In this respect it is of fundamental importance to achieve the a…

Debito e ingratitudine: la sovversione del tumulo donum nelle Troades di Seneca

2017

Il contributo indaga il sovvertimento delle dinamiche di dono e debito nelle Troades senecane, alla luce dei modelli etici illustrati nel De beneficiis. Nella tragedia, Seneca riscrive la relazione di reciprocità vigente tra Achille e i Greci secondo il modello analogico del debito. L’ombra di Achille, infatti, accusa gli Achei di sottrarre gli honores dovuti ai suoi Mani, dando prova di ingratitudine. Come praemium, l’eroe esige quindi il sacrificio di Polissena, che rappresenta un sovvertimento della pratica rituale dei doni ai morti. Per comprendere il significato antropologico di questa lettura, si opererà un confronto ragionato tra la rappresentazione della prassi cultuale con cui a Ro…

Circulating miR-21, miR-146a and Fas ligand respond to postmenopausal estrogen-based hormone replacement therapy--a study with monozygotic twin pairs.

2014

Biological aging is associated with physiological deteriorations and its’ remodeling, which are partly due to changes in the hormonal profile. MicroRNAs are known to post-transcriptionally regulate various cellular processes associated with cell senescence; differentiation, replication and apoptosis. Measured from the serum, microRNAs have the potential to serve as noninvasive markers for diagnostics/prognostics and therapeutic targets. We analysed the association of estrogen-based hormone replacement therapy (HRT) with selected microRNAs and inflammation markers from the serum, leukocytes and muscle tissue biopsy samples obtained from 54-62 year-old postmenopausal monozygotic twins (n=11 p…

Novel bioactive bromopyrrole alkaloids from the Mediterranean sponge Axinella verrucosa

2005

The Mediterranean sponge Axinella verrucosa has been investigated for its alkaloid composition and has been found to produce a complex mixture of bromopyrrole alkaloids. Along with the previously isolated compounds 5-18, four novel alkaloids of this class, compounds 1-4, have been isolated, and their structures established through spectroscopic methods. Compounds 1-4 were found to display neuroprotective activity against the agonists serotonin and glutamate in vitro.
