This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

objective(s): the aim of this study was to determine the important molecules involved in apoptosis induction by opium in jurkat cell line. materials and methods: jurkat cells were incubated 48 hrs with2.86×10-5 g/ml concentration of opium and apoptosis as well as expression levels of related molecules weremeasured. results: our results demonstrated that 50.3±0.2 percent of opium treated jurkat ...

We present a method for  the construction of compactlysupported $left (begin{array}{lll}1 & 0 & -1\1 & 1 & 0 \1 &  0 & 1\end{array}right )$-wavelets  under a mild condition. Wavelets inherit thesymmetry of the corresponding scaling function and satisfies thevanishing moment condition originating in the symbols of the scalingfunction. As an application, an  example is  provided.

A novel VSP imaging method that only requires a local velocity model around the well is presented. This method is denoted as a ‘local migration’, where the modelbased forward propagation and backward propagation operators are computed using a local velocity model between the well and the the target body. The velocity model for the complex overburden and salt body are not needed, and the source-...

In this note, we first give necessary and sufficient conditionsfor the Hunvitz stability of the family A of polynomials 6(s) = Pm,_(s),where the polynomials F i ( s ) are fixed; and the polynomials Manuscript received July 20, 1990; revised April 18, 1991, and October4. 1991.
