Molecular and patho-physiological basis of syndromes with developmental anomalies and intellectual disability

2013

Intellectual disability (ID) corresponds to abnormal intellectual performances and adaptive functions, beginning in childhood. It is estimated that 2-3% of individuals develop a ID, which represents a significant medical challenge since people with ID are frequently in situations of social dependence. Overall, a critical involvement of genetic factors in this disease is suspected. To date, several hundreds of genes are known to be responsible for ID. The ID is particularly characterized by extreme clinical and genetic heterogeneity, that made it resistant to conventional genetic studies. However, it is classicaly separated between syndromic ID, which may be clinically recognizable due to as…

A Stackelberg-game approach to support the design of logistic terminals

2014

This paper deals with the design of logistic terminals taking Sicily, in the South of Italy, as a case study. It focuses on consolidation terminals for truckers and addresses the problem of optimising location pattern and public share in investments. This problem is solved through a Stackelberg game between the designer and the collective of road carriers. So a bilevel approach combines a system-optimum problem, at the upper level, with the carrier equilibrium problem, at the lower level. The choice behaviour of the lower-level player is simulated by a random utility model. The output of the game suggests that private companies and society should share the investments and the public contrib…

Spontaneous emission of a sodium Rydberg atom close to an optical nanofibre

2019

International audience; We report on numerical calculations of the spontaneous emission rate of a Rydberg-excited sodium atom in the vicinity of an optical nanobre. In particular, we study how this rate varies with the distance of the atom to the bre, the bre's radius, the symmetry s or p of the Rydberg state as well as its principal quantum number. We nd that a fraction of the spontaneously emitted light can be captured and guided along the bre. This suggests that such a setup could be used for networking atomic ensembles, manipulated in a collective way due to the Rydberg blockade phenomenon.

Ultrafast ionization and rotational dynamics of molecules in strong laser fields

2021

The investigation of ultrafast molecular dynamics is of great importance towards the understanding of a variety of natural phenomena in physical and chemical sciences. With the rapid development of femtosecond laser systems and precision detection technologies, it is possible now to visualize and steer the motion of molecules in matter as well as the ultrafast dynamics of electrons and nuclei in molecules on a microscopic timescale. When a molecule is exposed to a strong laser field, its electrons can be freed or excited, which often triggers a rapid dissociation of the system, in which the released electrons and nuclei exhibit a strong correlation, while the electronic motion on attosecond…

Strongly confined atomic localization by Rydberg coherent population trapping

2020

In this letter we investigate the possibility to attain strongly confined atomic localization using interacting Rydberg atoms in a Coherent Population Trapping (CPT) ladder configuration, where a standing-wave (SW) is used as a coupling field in the second leg of the ladder. Depending on the degree of compensation of the Rydberg level energy shift induced by the van der Waals (vdW) interaction, by the coupling field detuning, we distinguish between two antiblockade regimes, i.e. a partial antiblockade (PA) and a full antiblockade (FA). While a periodic pattern of tightly localized regions can be achieved for both regimes, the PA allows much faster converge of spatial confinement yielding a …

Ultraprecise Rydberg atomic localization using optical vortices

2020

We propose a robust localization of the highly-excited Rydberg atoms, interacting with doughnut-shaped optical vortices. Compared with the earlier standing-wave (SW)-based localization methods, a vortex beam can provide an ultrahigh-precision two-dimensional localization solely in the zero-intensity center, within a confined excitation region down to the nanometer scale. We show that the presence of the Rydberg-Rydberg interaction permits counter-intuitively much stronger confinement towards a high spatial resolution when it is partially compensated by a suitable detuning. In addition, applying an auxiliary SW modulation to the two-photon detuning allows a three-dimensional confinement of R…

Kiedy sacrum sprofanowano, czyli sanktuarium św. Anny w czasie II wojny światowej

2016

The anastazy Piotr Polanko’s monograph “The Franciscans in annaberg during second World War” is anew publication concerning the history of the annaberg’s cloister just before the2ndWorld War and during the war. It has been published by st. antony’s Franciscan Publisher in 2013. It was elaborated on the basis of archives of annaberg’s Franciscan cloister. The author had to make an effort to translate the remaining documents from German. In his book he presents biographies of friars who lived in the cloister during first years of war, their ministry work with number of statistics regarding trips, sermons, retreats, pilgrimage movement, and then the moment of their exile from annaberg and gain…

Fridays for Future Wants to Save the World : But What Do People Think about the Movement?

2023

Fridays for Future is a movement initiated by Greta Thunberg designed to alert millions around the globe that we are amid a climate crisis by organising Friday protests. Led by Greta Thunberg, Fridays for Future has generated a lot of press in recent years: Greta has been listed among the World’s 100 Most Powerful Women as well as being twice nominated for the Nobel Prize. Greta was also named Time Magazine Person of the Year 2019. While her cause may be noble, many criticise the Fridays for Future movement—others simply do not believe in its global warming message. Twitter is a powerful electronic word of mouth (eWOM) platform, which, as a form of peer-to-peer communication, has the power …
