Background: Diagnosis of the early phase of mycosis fungoides (MF) is sometimes difficult. Loss of CD7 expression is considered a distinguishing characteristic of MF. The aim of this study was to determine the range of CD7 expression in MF and compare the results with benign inflammatory dermatosis and equivocal cases of possible MF. Methods: During a period of 30 months, we examined 15 patient...

This paper presents a new method for embedding digital watermarks into Bézier polynomial patches. An object surface is supposed to be represented by multiple piecewise Bézier polynomial patches. A Bézier patch passes through its four-corner control points, which are called data points, and does not pass through the other control points. To embed a watermark, a Bézier patch is divided into two p...

Bandwidth of proximity fed E-shaped microstrip antenna has been increased by gap-coupling pair of rectangular slot cut rectangular microstrip antennas along its radiating edges. The patch and slot dimensions were optimized to cover 800 – 1200 MHz frequency band. In this paper, a detail analysis to study the effects of slot and patch dimension on the broadband response in desired frequency band ...

Studies of the effects of patch size and isolation on plant species density have yielded contrasting results. However, much of the available evidence comes from relatively recent anthropogenic forest fragments which have not reached equilibrium between extinction and immigration. This is a critical issue because the theory clearly states that only when equilibrium has been reached can the numbe...

Simple metapopulation models with random disturbances are used in species conservation or management, relying on the condition for persistence that the per-patch colonization rate be greater than the per-patch extinction rate. For a general model incorporating the role of succession or patch age-dependent extinction, I show that persistence requires the per-patch colonization rate to be greater...

This paper presents rectangular, fractal and proximity coupled patch antennas on a two layer substrate with the air-gap. The antennas have been designed on εr = 2.2, h = 1.5748 mm with initial dimension 49 x 41.01 mm of simple rectangular patch. The simulated resonant frequency of rectangular patch is 2.42 GHz. The fractal antenna and the Fractal antenna with Layered Stack shows the multi band ...

A microstrip patch antenna is designed that have metallic ring coplanar to radiation patch for gain enhancement is proposed. The design forces conversion of the surface wave energy into the space wave energy by the scattering of surface waves from metallic ring. The metallic ring is placed around the metal patch at a distance of d1 from the edges of the metal patch and width of metallic ring is...

A Comparative study of rectangular and circular shape microstrip fed patch antennas for bluetooth application is presented in this paper. The resonance frequency is chosen at 2.45 GHz which is suitable for industrial scientific and medical (ISM) band applications. Computer Simulation Technology (CST) microwave studio is used as the software environment to design and compare the performance of t...
