Entanglement robustness via spatial deformation of identical particle wave functions

2021

We address the problem of entanglement protection against surrounding noise by a procedure suitably exploiting spatial indistinguishability of identical subsystems. To this purpose, we take two initially separated and entangled identical qubits interacting with two independent noisy environments. Three typical models of environments are considered: amplitude damping channel, phase damping channel and depolarizing channel. After the interaction, we deform the wave functions of the two qubits to make them spatially overlap before performing spatially localized operations and classical communication (sLOCC) and eventually computing the entanglement of the resulting state. This way, we show tha…

Comparison of tritium measurement techniques for a laser cleaned JET tile

2014

Abstract Over the last 7–8 years, two quantitative analyzing methods—accelerator mass spectrometry (AMS) and full combustion (FC) followed by scintillation detection have been applied for determining the tritium activity concentrations in JET divertor tiles. These methods have two main differences – the range of detection and the spatial resolution – and are thus complementary. However, these differences can also complicate the comparison of the two techniques for typical JET divertor samples. Therefore a cross comparison exercise for tritium measurements was performed between the two methods using specially produced identical standard samples. The cross comparison measurements were perform…

Am I riskier if I rescue my banks? Beyond the effects of bailouts

2021

Abstract We examine the relationship between bank bailouts and sovereign risk in 35 countries and 19 bailouts from 2005 to 2015. Bailouts negatively affect sovereign ratings, with rating agencies consistently perceiving higher risk when a country’s banking system has been rescued (risk-increasing effect). The increase in public debt as a result of the bank bailouts is the main mechanism through which the risk-increasing effect occurs. Moreover, financial soundness and banking market structure shape the impact of bailouts on sovereign risk. In particular, proactiveness in undertaking public bailouts for banking systems that are largely distressed – that is, risky and low profitable – and hig…

Am I riskier if I rescue my banks? The unintended effects of bailouts

2021

We examine the relationship between bank bailouts and sovereign risk in 35 countries and 19 bailouts during 2005–2015. Bailouts negatively affect sovereign ratings, with rating agencies consistently perceiving higher risk when the country’s banking system has been rescued (risk-increasing effect). Financial soundness and banking market structure shape the impact of bailouts on sovereign risk. In particular, proactiveness in undertaking public bailouts for banking systems that are largely distressed -risky and low profitable- and highly concentrated seems to lead to lower increases in sovereign risk. However, the strength of the connection between the public sector and the banking system nei…

Quantifying Mean Shape and Variability of Footprints Using Mean Sets

2005

This paper1 presents an application of several definitions of a mean set for use in footwear design. For a given size, footprint pressure images corresponding to different individuals constitute our raw data. Appropriate footwear design needs to have knowledge of some kind of typical footprint. Former methods based on contour relevant points are highly sensitive to contour noise; moreover, they lack repeatability because of the need for the intervention of human designers. The method proposed in this paper is based on using mean sets on the thresholded images of the pressure footprints. Three definitions are used, two of them from Vorob’ev and Baddeley-Molchanov and one morphological mean p…

Existence of a traveling wave solution in a free interface problem with fractional order kinetics

2021

Abstract In this paper we consider a system of two reaction-diffusion equations that models diffusional-thermal combustion with stepwise ignition-temperature kinetics and fractional reaction order 0 α 1 . We turn the free interface problem into a scalar free boundary problem coupled with an integral equation. The main intermediary step is to reduce the scalar problem to the study of a non-Lipschitz vector field in dimension 2. The latter is treated by qualitative topological methods based on the Poincare-Bendixson Theorem. The phase portrait is determined and the existence of a stable manifold at the origin is proved. A significant result is that the settling time to reach the origin is fin…

Raccordo tra pianificazione forestale e pianificazione antincendi boschivi.

2014

Il lavoro esamina le relazioni tra pianificazione forestale a livello regionale e locale(PFR e piani di assestamento forestale) e la relativa pianificazione antincendio. in particolare si evidenzia l'importanza della relazione con il livello locale nella programmazione di azioni selvicolturali volte a diminuire il livello di rischio e gestire il combustibile, nella possibilità di aumentare la resilienza dei sistemi.

Iteratively reweighted least squares in crystal structure refinements

2011

The use of robust techniques in crystal structure multipole refinements of small molecules as an alternative to the commonly adopted weighted least squares is presented and discussed. As is well known, the main disadvantage of least-squares fitting is its sensitivity to outliers. The elimination from the data set of the most aberrant reflections (due to both experimental errors and incompleteness of the model) is an effective practice that could yield satisfactory results, but it is often complicated in the presence of a great number of bad data points, whose one-by-one elimination could become unattainable. This problem can be circumvented by means of a robust least-squares regression that…
