The incidence of prostate cancer (PCA) was evaluated in 155 patients with isolated Atypical Small Acinar Proliferation (ASAP) found on initial prostate biopsy, after a medium-term follow-up (40 months) with at least one re-biopsy. Clinical and histological data were analysed. Cancer was detected in 81 of 155 (52.3%). The cancer detection rate was 71.6%, 91.3%, 97.5%, 100% at the 1st re-biopsy, ...

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

Background: Karyotype analysis has been the standard and reliable procedure for prenatal cytogenetic diagnosis since the 1970s. However, the major limitation remains requirement for cell culture, resulting in a delay of as much as 14 days to get the test results.CGH array technology has proven to be useful in detecting causative genomic imbalances or genetic mutations in as many as 15% of child...

In this paper a novel method for computing the radiation pattern and also the input impedance of a planar rectangular micro-strip antenna array with consideration of mutual coupling and mutual impedance is presented. Each two triangles with a common edge make an Edge element or RWG. Any such edge element is considered as an infinitesimal dipole. The electrical currents over each dipole can be c...

background: although the imbalance of cytokines in head and neck squamous cell carcinoma (hnscc) is well known, there is scarce data regarding its occurrence during dysplasia, before the malignant transformation. objective: to determine whether laryngeal dysplasia patients show a different cytokine profile than patients with cancer and healthy controls. methods: seventeen newly diagnosed, untre...

multiple input multiple output (mimo) radars are new generation of array radars that employ orthogonal waveforms for their transmit probing signals. despite of several advantages, this strategy results in transmission of uniform power in all angle of array’s viewing field. therefore, possibility of transmit beamforming and achieving coherent processing gain will be lost. many efforts have been ...
