Several proteins contain the domain homologous to the N-terminal half of band 4.1 protein, indicating the existence of a superfamily. The members of this 'band 4.1' superfamily are thought to play crucial roles in the regulation of cytoskeleton-plasma membrane interaction just beneath plasma membranes. We examined the structural diversity of this superfamily by means of the polymerase chain rea...

We present a C-band 6-mode 7-core fiber amplifier in an all-fiberized cladding-pumped configuration for space division multiplexed transmission supporting record 42 spatial channels. With optimized components (e.g. passively cooled pump laser diode, coupler, stripper), high power multimode light is coupled to the active without any noticeable thermal degradation and average gain of 18 dB noise ...

Abstract An isotropic tight-binding model with the nearest-neighbour hopping on a pyrochlore lattice gives rich variety of physical properties due to emergence flat-band. Moreover, by introducing spin-orbit coupling into this model, topological system changes significantly. This is well applicable some oxides called s1/s2 pyrochlores. In paper we apply an s2 oxide Pb 2 Ta O 7 and found characte...

We report resonant Raman scattering (RRS) by the TO, LO, and 2 LO modes of single wurtzite and zincblende GaAs nanowires. The optical band gap of wurtzite GaAs is 1.460 eV± 3meV at room temperature, and 35± 3meV larger than the GaAs zinc-blende band gap. Raman measurements using incoming light polarized parallel and perpendicular to the wire c axis allowed us to investigate the splitting of hea...

The results of the lowest frequency spectral survey carried out toward a molecular cloud and sensitive observations at selected frequencies are presented. The entire Arecibo C-band (4–6 GHz) was observed towards the cyanopolyyne peak of TMC-1 with an rms sensitivity of about 17–18 mK (about 2–2.5 mJy). In addition, a number of selected frequency ranges within the C-band and X-band (8–10 GHz) we...

In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed has short-sleeve shape, to expand impedance bandwidth, right left angles are subtracted symmetrically from lower half radiator. matching improved by etching slots in feed line adding L-shaped patches on both sides line. results sho...

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
