We study the performance over the last fifteen years of exports of typical, Made in Italy agri-food products. First, we estimate the aggregate elasticities of exports values with respect to world imports, export prices and the prices applied by our competitors. Second, we show that aggregate...

Hydrogen sorption using a manganese oxide anchored to PEEK (Poly(ether-ether-keton)) matrix was studied. The functionalization process and the obtained results on hydrogen storage capability of the synthesized polymer are reported. The functionalised polymer was characterised by Scanning...

We consider the low-temperature thermodynamic and magnetic properties of an ideal gas of particles obeying a generic fermion-like fractional statistics. The coefficients of the Sommerfeld expansion are calculated in terms of the central moments of the derivative of the density of entropy with...

We calculate the Hurst exponent H(t) of several time series by dynamical implementation of a recently proposed scaling technique: the detrending moving average (DMA). In order to assess the accuracy of the technique, we calculate the exponent H(t) for artificial series, simulating monofractal...

The f<Superscript>-γ</Superscript> sloped current noise power spectra, observed in organic semiconductors, have been interpreted within a variable range hopping mechanism of the fluctuations. The relative current noise power spectral density <InlineEquation ID="Equ1"> <EquationSource Format="TEX">${\cal S}(f)=S_I(f)/I^2$</EquationSource> </InlineEquation> exhibits a maximum at the trap-filling transition...</equationsource></inlineequation></superscript>

The study of behavioural and social phenomena has experienced a surge of interest over the last decade. One reason for this great attention is the huge amount of high quality data made available by the internet technologies. The many studies spanning concepts and problems belonging to economics,...

The ageing of farmers and lack of successors are major concerns for the future of the sector. The paper analyses the age structure of family workers with a twofold objective. The ageing dynamics is analyzed in order to seek out its inertial components as well as any new trends there may be. The...

We calculate the Shannon entropy of a time series by using the probability density functions of the characteristic sizes of the long-range correlated clusters introduced in [A. Carbone, G. Castelli, H.E. Stanley, Phys. Rev. E 69 (2004) 026105]. We define three different measures of the entropy...
