hereby we report a patient with thalassemia major having extradural cord compression at t3-t9 levels due to a mass of extramedullary hematopoiesis (emh) tissue, whose treatment was successful with hypertransfusion therapy alone. the patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. he suffered from paraparesis with a history of progre...

Five patients who underwent cardiopulmonary resuscitation (CPR) were studied by two-dimensional echocardiography to assess valve motion. The mitral valve remained open throughout the entire compression-release cycle of CPR. The aortic valve opened during the compression phase of CPR and closed during the release phase. The pulmonic valve moved toward the closed position during the compression p...

--The paper presents the lossless image compression based on prediction and contourlet transform methods in image processing. The lossless compression usually a less bandwidth or less memory and low compression ratio at the cost of image quality degradation. In the paper presents prediction and Contourlet transform methods are used. In prediction method, convert the color image to YVU and then ...

In intact chronically instrumented dogs, left ventricular dynamics were studied during cardiopulmonary resuscitation (CPR). Electromagnetic flow probes measured cardiac output and coronary blood flow, ultrasonic transducers measured cardiac dimensions, and micromanometers measured left ventricular, right ventricular, aortic, and intrathoracic pressures. The dogs were anesthetized with morphine,...

We present a method for both lossless and lossy compression of bi-level images that consist mostly of printed or typed text. The key feature of the method is soft pattern matching, a way of making use of the information in previously encountered characters without risking the introduction of character substitution errors. We can obtain lossless compression which is about 20% better than that of...

This paper presents a neural network based technique that may be applied to data compression. The proposed technique breaks down large images into smaller windows and eliminates redundant information. Finally, the technique uses a neural network trained by direct solution methods. Conventional techniques such as Huffman coding and the Shannon Fano method are discussed as well as more recent met...

In this paper, we consider the compression of high-definition video sequences for bandwidth sensitive applications. We show that down-sampling the image sequence prior to encoding and then up-sampling the decoded frames increases compression efficiency. This is particularly true at lower bit-rates, as direct encoding of the high-definition sequence requires a large number of blocks to be signal...

Osteoporotic Vertebral compression fractures (OVCFs) constitute a major health care problem in western countries, not only because of the high incidence of these lesions but also due to their direct and indirect negative consequences for patient health-related quality of life and the costs to the health care system. Compression fractures lead to a loss of height of the vertebral segment, and th...

In many imaging applications, mobile agents—such as untethered reconnaissance robots and micro air vehicles—transmit and receive bandwidth-intensive image data over wireless networks. A key issue in developing small, mobile agents is minimizing their power requirements. Compressing the data before transmission is a direct way to significantly decrease power requirements; thus, effective image c...
