We use the conformal group to study non-local operators in conformal field theories. A plane or a sphere (of any dimension) is mapped to itself by some subgroup of the conformal group, hence operators confined to that submanifold may be classified in representations of this subgroup. For local operators this gives the usual definition of conformal dimension and spin, but some conformal field th...

A printed circular open-loop antenna is introduced as a simple structure for producing circular polarization, the antenna is fed with a coaxial probe. By introducing a gap within the circular loop a traveling-wave current is excited and thus circularly polarized radiation can be achieved. An optimized circularly polarized antenna is designed through numerical analysis using a so-called parametr...

Nonmagnetostrictive CoFeSiB alloy wires were subjected to cold drawing processing followed by annealing under tension, in order to induce the formation of circular magnetic anisotropy. The axial (M Z – HZ) and circular (M f – Hf) hysteresis loops indicate the existence of induced transverse anisotropy, with the magnitude of the anisotropy field being dependent on the processing conditions, whil...

In 1963 by Dulbecco and Vogt (1963) and Weil and Vinograd (1963) discovered that doublestranded DNA of the polyoma virus exists in a closed circular form. At present it is generally acknowledged that this form is typical of bacterial DNA and of cytoplasmic DNA in animals. Furthermore, giant DNA molecules in higher organisms form loop structures held together by protein fasteners in which each l...

conclusions although dcl is rare, physicians should mind its occurrence it in any immunocompromised patient with diffuse cutaneous ulcers refractory to treatment. case presentation here is the report of a 43-year-old man referred to infectious diseases clinic in boo-ali hospital (zahedan city, southeastern iran) because of multiple chronic ulcers for five months. during the time, he had been vi...
