Histologic diagnosis ultimately determines the prognosis and treatment of lesions causing spinal cord compression. Modern imaging techniques have revolutionized the procedure of localizing lesions presenting with signs and symptoms of spinal cord compression. As a result, these lesions are more accessible for fine needle aspiration and biopsy. A quick diagnosis is possible if cytologic preparat...

In this study, we determine the fine spectrum of the matrix operator ∆ defined by an upper triangle double band matrix acting on the sequence space c0 with respect to the Goldberg’s classification. As a new development, we give the approximate point spectrum, defect spectrum and compression spectrum of the matrix operator ∆ on c0. AMS subject classifications: 47A10, 47B37

In the modulation-filtering based speech enhancement method, noise suppression is achieved by bandpass filtering the temporal trajectories of the power spectrum. In the literature, some authors use the power spectrum directly for modulation filtering, while others use different compression functions for reducing the dynamic range of the power spectrum prior to its modulation filtering. This pap...

Lymphangiomas are benign lesions consisting of abnormal proliferations of lymphatic vessels. Lymphangiomas associated with bone involvement, particularly in vertebral bodies, accompanied by cord compression, are extremely rare, and our literature review yielded only a few relevant reports. We describe a 61-year-old man presenting with progressive paraparesis and sphincter disturbance of 5 month...

ICER-3D is a progressive, wavelet-based compressor for hyperspectral images. ICER-3D is derived from the ICER image compressor. ICER-3D can provide lossless and lossy compression, and incorporates an error-containment scheme to limit the effects of data loss during transmission. The three-dimensional wavelet decomposition structure used by ICER-3D exploits correlations in all three dimensions o...

—This paper presents a new approach for watermarking of digital video providing robustness against MPEG compression. The initial video is decomposed by one-dimensional 2 Level Wavelet Transform. The low pass filtered LL video stream is used for embedding the procedure. Every frame of this sequence undergoes a 16x16 block wise DCT before the embedding procedure is applied on selected coefficient...
