a group g is said to be a (pf)c-group or to have polycyclic-by-finite conjugacy classes, if g/c_{g}(x^{g}) is a polycyclic-by-finite group for all xin g. this is a generalization of the familiar property of being an fc-group. de falco et al. (respectively, de giovanni and trombetti) studied groups whose proper subgroups of infinite rank have finite (respectively, polycyclic) conjugacy classes. ...

Abstract Multi-photon entangled graph states are a fundamental resource in quantum communication networks, distributed computing, and sensing. These can principle be created deterministically from emitters such as optically active dots or defects, atomic systems, superconducting qubits. However, finding efficient schemes to produce has been long-standing challenge. Here, we present an algorithm...

background: magnetite (fe3o4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. to use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. functionalization of magnetite nanoparticles is performed by different surfactant...

objectives: the idiopathic minimal change nephritic syndrome (nephrosis) is responsible in 80% of nephritic syndromes in children. it is a clinical entity characterized by inter and outer renal parameters. main factor in glomerolar damages is proteinuria and the role of ige is possible. aim: in this research, serum ige concentrations were measured in children with nephrosis in three stages: rel...
