We propose a variant of a slotted cavity for high-current gyrotrons based on the coupling of modes with proportional azimuthal indexes and close eigenvalues. A finite-element method simulation is presented, which confirm its high selectivity. 3D PIC

We present the main development stages of a sub-GW Ka-band gyrotron with TM51 operating mode. For discrimination of TE-type modes, an axial-slit resonator is proposed. The analytic theory of its cavity is developed and calculations using finite-eleme

We discovered a specific property of the eigenmodes of a cylindrical waveguide, due to which efficient mode excitation at ultrahigh (s=4n+1, n is integer) multiples of the gyrofrequency can be provided by a polyhelical weakly relativistic electron be

Gap junctions are clusters of intercellular channels directly connecting the cytoplasm of adjacent cells. These channels are formed by proteins named connexins and are present in all metazoan organisms where they serve diverse functions ranging from

Vertebrate gap junctions are aggregates of transmembrane channels which are composed of connexin (Cx) proteins encoded by at least fourteen distinct genes in mammals. Since the same Cx type can be expressed in different tissues and more than one Cx t

Based on a single mode distributed non-stationary model of the gyrotron, we investigate the influence of the non-uniformity of the guiding magnetic field on the processes of rogue-wave generation. We estimate the allowable level of non-uniformity at

Gap Junctions in the Nervous System
Synapses are classically defined as close connections between two nerve cells or between a neuronal cell and a muscle or gland cell across which a chemical signal (i.e., a neurotransmitter) and/or an electrical signal (i.e., current-carrying ions) ca

Introduction Delayed renal graft function (DGF) is associated with various factors and with a higher complication rate in the posttransplant period. Determination of center-specific risk factors may help to reduce the incidence of DGF and improve tra
