We analyse the data for the proton structure function F2 over the entire Q 2 domain, including especially low Q 2 , in terms of perturbative and non-perturbative QCD contributions. The small distance configurations are given by perturbative QCD, while the large distance contributions are given by the vector dominance model and, for the higher mass qq states, by the additive quark approach.

ABSTRACT A new current-mode universal active-RC filter is proposed. The proposed circuit is based on a new universal passive filter topology. Two Fully Differential Current Conveyors (FDCCII) are used to construct a universal active-RC filter from this passive filter. The FDCCII based proposed filter has only grounded resistances and capacitors as the passive elements. The circuit simultaneousl...

My paper addresses an issue that is rarely discussed in the economics literature: how does the economic actors’ trust in each other and in the legal and political institutions affect a country’s economic performance? The first part of the paper is an empirical analysis of the interrelationship between confidence in institutions in different countries, the economic actors’ willingness to coopera...

Using the concept of nullors, an unified methodology is presented which can be used for realizing fully differential current mode filters using a variety of building blocks which can be represented by nullators and norators. The workability of the proposed approach is verified by the SPICE simulation results of an exemplary universal biquad made from multiple-output-currentconveyors. This exemp...

This paper reports a multitude of HSPICE simulation results corresponding to high-order (fifth, sixth and tenth) differential classA log-domain lowpass and bandpass ladder filter topologies. The designs are elliptically approximated and were obtained by means of an appropriately extended version of the XFILTER filter compiler. The non-desirable effect of the BJT finite beta is shown; circuit mo...

The recent progress of BSIM (Berkeley Short-channel IGFET Model) SPICE models extended for SOI transistors are reviewed. The models cover partially depleted (PD), fully depleted (FD) and dynamic depletion (FD) (automatically transition between PD and FD). The key concept of dynamic depletion will be discussed.
