Pancreatic neuroendocrine tumors (PNET) are fairly uncommon. Recent data highlight the importance of EUS in diagnosis of PNET. With this background, we decided to review our experience from a tertiary cancer center with regard to the presentation and clinical features of PNET and the diagnostic utility of EUS-FNA in this scenario. We identified patients who(More)
In this paper, a single element receiver for short-range shallow water communication is proposed as an alternative to costly beamformer structures by utilizing state-of-the-art iterative demodulation techniques. The proposed receiver structure employs an adaptive decision feedback equalizer (DFE) and bit interleaved coded modulation with iterative decoding(More)
An adaptive iterative receiver structure for the shallow underwater acoustic channel (UAC) is proposed using a decision feedback equalizer (DFE) and employing bit-interleaved coded modulation with iterative decoding (BICM-ID) in conjunction with adaptive Doppler compensation. Experimental results obtained from a sea trial demonstrate that the proposed(More)
We present extrinsic information transfer (EXIT) chart analysis of iterative equalizer implemented using adaptive decision feedback equalizers (DFE) and bit-interleaved coded modulation with iterative decoding (BICM-ID) to analyse the performance. It is shown from the EXIT chart analysis that the performance of the BICM-ID based receiver strongly depends on(More)
Background: Tuberculosis is a major contributor of exudative pleural effusion which is the second most common extra-pulmonary manifestation of tuberculosis following tubercular lymphadenitis. Tuberculous pleural effusion is lymphocytic and exudative characteristics. The analysis adenosine deaminase (ADA) activity is a very useful diagnostic approach to(More)
Background: Cholesteatoma is potentially dangerous condition as it can extend and erode into adjacent structures and can cause various serious complications. HRCT temporal bone very clearly depicts the anatomy of various small important structures in middle and inner ear cavity. Hence it is an excellent modality and investigation of choice in diagnosing and(More)
