Already in the early studies of the nuclear current oper- ators, the prominent role of the chiral symmetry (symmetry of QCD if the quark masses are set to zero) in the nuclear forces and currents was well appreciated [27]. Basically in all realistic models the longest range interactions are...

In this review, after a general introduction to the Effective String Theory (EST) description of confinement in pure gauge theories, we discuss the behaviour of EST as the temperature is increased. We show that, as the deconfinement point is approached from below, several universal features of ...
The output signal-to-noise ratio (SNR) of a monostatic radar system is simply the ratio of the power Pr received at the input terminals of the receiver to the noise power of the system: (1.4)SNR=PrkTB=(PTG4πR2)(Aeσ4πR2)(1kTB)(10−0.2αR) where R = the radar range or the...
6. Both the neat PMMA and PMMA/GNP composite are found to be nearly transparent to the THz waves, with SE values always lower than 0.2 dB in the experimental frequency range. Indeed, the EMI shielding of the polymer-CVD graphene nanolaminates originates from the intrinsic high electrical ...
The effective parameters are further used for the dispersion analysis of surface plasmons localized at the metasurface. The obtained effective conductivity describes correctly the dispersion law of both quasi-TE and quasi-TM plasmons in a wide range of optical frequencies as well as the peculiarities ...
