In this study, we discuss the magnetic moment of Pcs(4338) and Pcs(4459) hidden-charmed pentaquarks, which are closely related to their substructures. The moments these states calculated with help QCD light-cone sum rules method quantum numbers I(JP)=0(1/2?) I(JP)=0(3/2?) for Pcs(4459), respectively. Our predictions ?Pcs=0.34±0.12?N state, ?Pcs=?1.67±0.58?N state. As a by-product, isospin?1 par...
This paper presents a new design of a CPW-Fed multi bands planar antenna. This antenna can be integrated easily with passive and active elements. The proposed antenna is suitable to operate for GPS, PCS and WiMAX bands. Its entire area is 52.3x52.6mm2 and is employed on an FR-4 epoxy substrate and fed by a 50 Ohm coplanar line. The antenna parameters have been analyzed and optimized by using AD...
In multiple sclerosis Oligodendrocytes are obliterated by the immune system. neural stem/ progenitor cells (NS/P Cs) have the capacity to differentiate into mature myelinating oligodendrocytes. In embryonic mouse cortex oligodendrocyte progenitor cells (OPCs) are more abundant than the ganglionic eminence. Doing gene set enrichment analysis using DAVID and Panther websites it was shown that Gpr...
A novel fractal called Fractal Clover Leaf (FCL) is introduced and shown to have well miniaturization capabilities. The proposed patches are fed by L-shape probe to achieve wide bandwidth operation in PCS band. A numerical parametric study on the proposed antenna is presented. It is found that the antenna can attain more than 72% size reduction as well as 17% impedance bandwidth (VSWR<2), in co...
Abstract In the wide world of 2D materials, hexagonal boron nitride (hBN) holds a special place due to its excellent characteristics. addition thermal, chemical and mechanical stability, hBN demonstrates high thermal conductivity, low compressibility, band gap around 6 eV, making it promising candidate for many groundbreaking applications more specifically in van der Waals heterostructures. Mil...
A slot line fed planar dipole antenna with a parasitic strip for wide band applications is presented. The presented antenna offers a 2:1 VSWR bandwidth from 1.66 to 2.71 GHz covering the DCS/ PCS/UMTS and IEEE 802.11b/g bands with a gain better than 6.5 dBi. The uniplanar design, simple feeding, and high gain make it a versatile antenna for wireless applications. © 2009 Wiley Periodicals, Inc. ...
A compact multiband handset antenna including MIMO antenna operation for LTE 13 band (746 ∼ 787MHz) applications is proposed. The proposed antennas are separately located on the top and bottom portions of a mobile handset in order to use the antenna area more effectively. The proposed antenna achieves isolations of higher than 14 dB, enveloped correlation coefficients (ECC) of less than 0.25, a...
In this paper the design of a new multistandard antenna is proposed suitable for major cellular bands. A C-shaped radiator with a microstrip feed line is proposed which supports major cellular communication band like AWS, DCS, DECT, PCS, PHS, 3G, UMTS, DSR, Wi-Bro, ISM, and DMB in the range of 1.7-2.9 GHz. The designed antenna is simulated using CST Microwave Studio to achieve such wide frequen...
