We present the first upper limit on gravitational wave (GW) backgrounds at an unexplored frequency of 0.2 Hz using a torsion-bar antenna (TOBA). A TOBA was proposed to search for low-frequency GWs. We have developed a small-scaled TOBA and successfully found Ω(gw)(f)<4.3×10(17) at 0.2 Hz as demonstration of the TOBA's capabilities, where Ω(gw)(f) is the GW energy density per logarithmic frequen...
Recently, superconductivity was discovered in the infinite layer of hole-doped nickelates NdNiO$_{2}$. Contrary to this, LaNiO$_{2}$ is still under debate. This indicates crucial role played by $f$ electrons on electronic structure and pairing mechanism infinite-layer nickelates. Here we discuss electron correlations states their influence structure. We show that lattice parameters are good agr...
A small 3-Dimensional (3-D) multi-band antenna of “F” shape is proposed for portable phones’ applications. The designed configuration of the proposed antenna is different from traditional Planar Inverted-F Antenna (PIFA) radiators. The proposed antenna has the good characteristics of wide band. The ratio of impedance bandwidth to the central frequencies 2.5 and 5.1GHz is 28.6% and 9%, respectiv...
This paper proposes a microstrip patch antenna for 2.45 GHz Industrial Scientific Medical (ISM) band Wireless Body Area Network (WBAN) applications. To enhance the front-to-back ratio (F/B) and specific absorption rate (SAR), an electrically coupled LC resonator is introduced. The overall dimensions of the proposed antenna are 54 mm × 45 mm × 2.4 mm and it has a gain of over 1 dBi for the entir...
We show that there do not exist adaptive confidence bands for curve estimation except under very restrictive assumptions. We propose instead to construct adaptive bands that cover a surrogate function f which is close to, but simpler than, f . The surrogate captures the significant features in f . We establish lower bounds on the width for any confidence band for f and construct a procedure tha...
The wide-band circularly polarised (CP) monopole antenna structure described in this article combines a defective ground plane with an f-shaped radiating that is intended for impedance bandwidth and high axial ratio (IBW). faulty etched as twin rectangular slots, F-shaped slot, square slot corner cut off. proposed 25 × 1.6 mm3 total. prototype of the optimised antenna’s far-field characteristic...
Let M be a map on a surface F . A geometric realization of M is an embedding of F 2 into a Euclidian 3space R with no self-intersection such that each face ofM is a flat polygon. In our talk, we shall prove that every triangulation G on the projective plane has a face f such that the triangulation of the Möbius band obtained from G by removing the interior of f has a geometric realization.
