We discuss the main characteristics that must be satisfied by Josephson junctions for metrological applications and, specifically, in the development of voltage standards of new generation. Data reported in the literature for the most established technologies, like SNS (Superconductor-Normal conductor-Superconductor), SINIS (SuperconductorInsulator-Normal conductor-Insulator-Superconductor) and...

In [6], S. Bloch conjectures a formula for the Artin conductor of the l-adic etale cohomology of a regular model of a variety over a local field and proves it for a curve. The formula, which we call the conductor formula of Bloch, enables us to compute the conductor that measures the wild ramification by using the sheaf of differential 1-forms. In this paper, we prove the formula in arbitrary d...

We experimentally demonstrate the validity of nonequilibrium fluctuation relations by using a quantum coherent conductor. In equilibrium the fluctuation-dissipation relation leads to the correlation between current and current noise at the conductor, namely, the Johnson-Nyquist relation. When the conductor is voltage biased so that the nonlinear regime is entered, the fluctuation theorem has pr...

Coordinated action between music orchestra performance, driven by a conductor, is a remarkable instance of interaction/communication. However, a rigorous testing of inter-individual coordination in an ecological scenario poses a series of technical problems. Here we recorded violinists' and conductor's movements kinematics in an ecological interactive scenario. We searched for directed influenc...

We investigate the conductance of normal-conductor/graphene/normal-conductor NGN junctions for arbitrary on-site potentials in the normal and graphitic parts of the system. We find that a ballistic NGN junction can display insulating behavior even when the charge-carrier density in the graphene part is finite. This effect originates in the different k intervals supporting propagating modes in g...

Following the construction of two hybrid magnets, we intend to build up a third hybrid magnet which will produce about 30 T. A prereacted multifilamentary Nb Sn conductor will be employed for the 12 T superconducting part of the hybrid. As a first step for the project, we have designed, constructed and tested a magnet which consists of 14 double-pancakes made of a prereacted multifilamentary Nb...

Transient eddy current problem is solved in the present paper by the method of the Laplace transform for the case of a double conductor line located parallel to a conducting half-space. The Fourier sine and cosine integral transforms are used in order to find the Laplace transform of the solution. The inverse Laplace transform of the solution is found in closed form. The integrated electromotiv...

Different dynamic line rating systems have been developed for monitoring overhead lines. The aim of these systems is to estimate the actual rating of electric lines and use all the available capacity to achieve a more efficient use of the existing lines. Some systems have been installed in a distribution pilot line to evaluate the different uncertainty levels. Systems that measure weather param...

The high-sensitive micro eddy-current testing (ECT) probe composed of planar meander coil as an exciter and spin-valve giant magneto-resistance (SV-GMR) sensor as a magnetic sensor for bare printed circuit board (PCB) inspection is proposed in this paper. The high-sensitive micro ECT probe detects the magnetic field distribution on the bare PCB and the image processing technique analyzes output...

trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...
