We present a deep multi-colour CCD mosaic of the Coma cluster (Abell 1656), covering 5.2 deg in the B and r bands, and 1.3 deg in the U band. This large, homogeneous data set provides a valuable low redshift comparison sample for studies of galaxies in distant clusters. In this paper we present our survey, and study the dependence of the galaxy luminosity function (LF) on passband and radial di...

We present the influences of electronic and magnetic correlations doping evolution on groundstate properties recently discovered superconductor Ba$_{2}$CuO$_{4-\delta}$ by utilizing Kotliar-Ruckenstein slave boson method. Starting with an effective two-orbital Hubbard model (Scalapino {\it et al.} Phys. Rev. {\bf B 99}, 224515 (2019)), we demonstrate that increasing concentration, paramagnetic ...

A 72 year old woman presented with a suspected myocardial infarction. An echocardiograph showed no acute changes but her plasma creatine kinase (CK) activity was increased at 343 U/l (< 175 normal range). The apparent creatine kinase-MB activity by a CK-M subunit immunoinhibition assay was 350 U/l. In view of the discrepancy between the total creatine kinase and CK-MB activity plasma creatine k...

In this project a wideband E-shaped patch antenna using Uslots is to be described. A patch antenna, also known as a rectangular micro strip antenna, is an antenna with a low profile, can be mounted on a flat surface. A wide range of radiation pattern can be achieved with this antenna and it is inexpensive. The wide-band mechanism is explored by investigating the behavior of the currents on the ...

Wave concept iterative procedure (WCIP) is used to analyze dual-band and enhanced band frequency selective surfaces (FSS). In the metallic U-shaped simple FSS, a fine-tune of the two rejected bands is insured by varying independently the length of the two parallel U-shaped FSS strips. The dual band response can also be obtained from the two-level rectangular conducting patches FSS. An enhanced ...

A band pass filter with tilted ladder shaped patch and U-shaped geometries is proposed in this paper. Feed are connected at the end of open ended stubs. Presented filter is suitable for the application of wireless application in L-band range. A flat passband response can be achieved when it is employed to implement a bandpass filter. The resonator also exhibits attenuation poles close to the ed...

We use a combination of conventional density functional theory (DFT) and post-DFT methods, which include the local density approximation plus Hubbard U (LDA + U ), PBE0, and self-consistent GW, to study the electronic properties of Ni-substituted PbTiO3 (Ni-PTO) solid solutions. We find that LDA calculations yield unreasonable band structures, especially for Ni-PTO solid solutions that contain ...

Changes in the location of key ice facies/zones on the Greenland ice sheet are considered key indicators of global climate change, Microwave scatterometers are effective tools for monitoring these changes. Measurements for three Ku-band scatterometers, SASS (1978), NSCAT (1996), and SeaWinds (1999-present), span a 23 years period. while the ERS scatterometer (C-band) offers a continuous 9 year ...

A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28mm × 24mm × 1.6mm is excited by a 50Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on th...
