No full textThe chapter deals with a decision issued by the CJEU (Cadeddu) and two pending cases (HB v INPS and IC v INPS; Société Génerale) dealing with the application of EU primary and secondary law in the filed of direct taxation. With regard to Cadeddu, the analysis is purported at testing the reasoning underlying the decision of the Court against the generally accepted rules of interpretation applicable to EU law and the previous case law of the CJEU. With regard to the two pending cases, the chapter aims at proving readers with a possible outcome thereof, based on the prior decisions of the Court in similar cases and the general principles of EU law

No full textDirectionality in Dark Matter search
No full textThe potentialities of an argon Dark Matter detector with real-time directional information located at Laboratori Nazionali del Gran Sasso (LNGS) are discussed. Columnar recombination combined with a dual-phase Liquid Argon Time Projection Chamber (TPC) provides a promising approach for a directional detector. Even in the case of a minimal angular resolution, a very clear signature of WIMP scattering on target nuclei is shown to be expected. Indeed, the ratio of horizontal to vertical events changes by a factor of four during the day and has a characteristic sidereal-day periodicity. Demonstration of a directional sensitivity in a large Liquid Argon TPC could have high impact on the future experiments in the field, opening up the potential to find conclusive evidence for dark matter or disprove the WIMP hypothesis at and above the mass range explored by planned accelerator experiments
The diet problem, a mathematical approach
No full textBackground and aim: Differential equations have always been used to modelize physical phenomena from other branches of science: physics, biology, chemistry, engineering, computer science etc. The aim of this paper is to find a simple mathematical model that can describe the variation of weight depending on
time and calories intake. The idea is simple and is based on the so-called Malthus mathematical model, an ordinary differential equation associated to an initial condition, which studies the growth of a population with respect to a certain phenomenon or under the influence of external/internal factors. Methods: The most basic and intuitive Malthus model is formalized as follows: given P=P(t) the function that describes the size of a population, the ordinary differential equation P’(t)=rP expresses the fact that the rate of change of the size of the population (i.e. the derivative P’(t) with respect to the time t) depends directly on the size of the population itself multiplied by a factor r that represents the population growth rate, sometimes called Malthusian parameter. The equation needs to be associated to an initial condition, say P0 = P(0), which represents the size of the population at the time t=0. The solution of this problem can be calculated explicitly and this allows to
precisely link the weight loss (or gain) according to calories intake, expected time, gender, kind of physical activity etc. Results: Our model considers age, gender and physical activity and allows us to discuss how to calculate a reasonable diet plan depending on different variables. Morever, it can give an idea, by studying the
asymptotic behaviour of the solution, why the so-called miracle-diets can’t work, why long diet plans usually fail and how to deal with severe obesity. Conclusions: The results obtained by means of this mathematical model shed new light on how to approach the creation of a reasonable diet plan. These results can be improved
by introducing numerical simulations, which is the aim of a subsequent paper
Reinterpreting the weak mixing angle from atomic parity violation in view of the Cs neutron rms radius measurement from COHERENT
No full textUsing the first model independent average neutron rms radius of Cs133 and I127 obtained from the analysis of the coherent elastic neutrino-nucleus scattering data of the COHERENT experiment, we show the effect on the weak mixing angle measurement from the atomic parity violation (APV) in cesium. Despite that the large uncertainty on the neutron skin measurement makes it difficult to draw statistically significant conclusions on the weak mixing angle, we exploit the fact that the APV result is highly sensitive to the cesium neutron rms radius, Rn, to combine the APV and the COHERENT measurements in order to get a better determination of Rn, assuming that the standard model is correct. The value of Rn=5.42±0.31 fm is obtained, improving significantly the current uncertainty. This result allows to infer a meaningful value of the cesium neutron skin, the difference between the neutron and proton distribution radii, equal to ΔRnp=0.62±0.31 fm, showing for the first time a 2σ deviation from zero
