Saturation and coherence effects in the modified KGBJS equation

2013

We solve the modified non-linear extension of the CCFM equati on KGBJS equation numerically for certain initial conditions and compare the resulting gl uon Green functions with those obtained from solving the original CCFM equation and the BFKL and BK equations for the same initial conditions. We improve the low transversal momentum behaviour of the KGBJS equation by a small modification.

Burnout prevalence in pediatricians of general hospitals

2008

OBJETIVO: Analizar la prevalencia del síndrome de quemarse por el trabajo (burnout) en pediatras de hospitales generales siguiendo criterios de diferentes países. MÉTODOS: Estudio transversal, no aleatorio, realizado en Buenos Aires, Argentina, en 2006. La muestra la formaron 123 pediatras que trabajaban en Servicios de Pediatría de hospitales generales, 89 fueron mujeres (72,4%) y 34 hombres (27,6%). Los datos fueron recogidos mediante un cuestionario anónimo y autoadministrado. El SQT fue diagnosticado utilizando el Maslach Burnout Inventory, con diferentes criterios para establecer su prevalencia. RESULTADOS: La prevalencia del SQT, varió en función del criterio utilizado: siguiendo los …

Highly tunable optically switched time delay line for transversal filtering

2003

A novel tunable dispersion device, based on two chirped fibre gratings subjected to non-uniform magnetic fields, is presented. A large degree of tunability is achieved from 250 to 750 ps/nm. This is used to demonstrate RF filtering in the 3-11 GHz range.

Advanced Optical Processing of Microwave Signals

2005

The authors present a review on the recent approaches proposed to implement transversal RF filters. Different tunable transversal filters consisting of wavelength tunable optical taps and those employing the tunability of dispersive devices are presented showing their high-performance characteristics. A comprehensive review of the fundamentals and a discussion on the main limitation of these structures are also included.

Preparing students to participate to the didactic activities of university teacher

2016

«Student Voice» è un movimento pedagogico nato negli anni Novanta nei Paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia): esso sostiene la partecipazione attiva e responsabile degli studenti che frequentano la scuola e l’università nella didattica dei docenti, nella ricerca universitaria e nelle politiche educative e culturali che li riguardano. Nella ricerca sperimentale qui presentata, si è voluta prestare attenzione alla partecipazione degli studenti universitari (n. 33) alle attività didattiche di un docente di pedagogia sperimentale. Si è scelto di adottare due metodi d’intervento: la scrittura espressiva, come metodo di analisi del futuro prefigurato nelle aspettat…

Glassy dynamics in confinement: planar and bulk limits of the mode-coupling theory.

2014

We demonstrate how the matrix-valued mode-coupling theory of the glass transition and glassy dynamics in planar confinement converges to the corresponding theory for two-dimensional (2D) planar and the three-dimensional bulk liquid, provided the wall potential satisfies certain conditions. Since the mode-coupling theory relies on the static properties as input, the emergence of a homogeneous limit for the matrix-valued intermediate scattering functions is directly connected to the convergence of the corresponding static quantities to their conventional counterparts. We show that the 2D limit is more subtle than the bulk limit, in particular, the in-planar dynamics decouples from the motion …

Efficiencies of logical Bell measurements on Calderbank-Shor-Steane codes with static linear optics

2019

We show how the efficiency of a logical Bell measurement (BM) can be calculated for arbitrary Calderbank-Shor-Steane (CSS) codes with the experimentally important constraint of using only transversal static linear-optical BMs on the physical single-photon qubit level. For this purpose, we utilize the codes' description in terms of stabilizers in order to calculate general efficiencies for the loss-free case, but also for specific cases including photon loss. These efficiencies can be, for instance, used for obtaining transmission rates of all-optical quantum repeaters. In the loss-free case, we demonstrate that the important class of CSS codes with identical physical-qubit support for the t…

Fluids in extreme confinement.

2012

For extremely confined fluids with two-dimensional density $n$ in slit geometry of accessible width $L$, we prove that in the limit $L\to 0$ the lateral and transversal degrees of freedom decouple, and the latter become ideal-gas-like. For small wall separation the transverse degrees of freedom can be integrated out and renormalize the interaction potential. We identify $n L^2 $ as hidden smallness parameter of the confinement problem and evaluate the effective two-body potential analytically, which allows calculating the leading correction to the free energy exactly. Explicitly, we map a fluid of hard spheres in extreme confinement onto a 2d-fluid of disks with an effective hard-core diame…
