A compact and sharp rejection UWB microstrip bandpass filter is developed using left handed metamaterials. For realizing a backward-wave propagation medium, two split ring resonator (CSRR) in the back substrate side and also one series capacitor etched in the host line, are used to produce a negative effective ε and μ, simultaneously. Moreover, in the proposed structure, two doublets parallel c...

Abstract Background Coupling between RV contractile function and pulmonary circulation (PC) reflects the comprehensive performance of by integrating afterload contractility. RV-PC coupling is nowadays frequently expressed non-invasively measured ratios TAPSE/RVSP RVFWLS/RVSP. It has been shown that it decreases slightly during exercise, whereas no known data exist on how dobutamine does affect ...

The buried hetero-structure (BH) InGaAsP-InP waveguide is used for asystem of double microring resonators (DMR). The light transmission and location ofresonant peaks are determined for six different sets of ring radii with different ordermode numbers. The effect of changing middle coupling coefficient on the box likeresponse is studied. It is found that the surge of coupling coefficient to the ...

Meson-baryon couplings between positive and negative parity baryons are investigated using two point correlation functions in the soft meson limit. We find that the πN N * coupling vanishes due to chiral symmetry, while the ηN N * coupling remains finite. We perform an analysis based on the algebraic method for SU (2) and SU (3) chiral symmetry, and find that baryon axial charges play an essent...

in this paper deflection and free vibration of sandwich panel is studied. the core of sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of carbon fiber reinforced plastic and k-aryl/epoxy covering. the governing equations are deduced from the first order sheer deformation theory (fsdt) and they are solved using generalized differential quadrature metho...

the catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [pd{c6h2(ch2nh2-(ome)2,3,4}(µ-cl)]2)2) and [pd{c6h2(ch2nh2-(ome)2,3,4}cl(pph3)](3), was investigated in heck cross-coupling reaction. these complexes are more active and efficient catalysts for heck cross-coupling reaction. the palladium complexes 2 and 3 is employed in the heck cross-coupling reaction between styrene a...

Although evidence suggests that delta-beta coupling may provide a useful index of trait level cortico-subcortical cross talk in baseline contexts, there has been little work done to clarify the role of delta-beta coupling across contexts and in association with other physiological markers of emotion processing. We examined whether individual differences in coupling were visible across both posi...

finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.
