Tumor volume has been considered an important variable in determining the probability of prostate-specific antigen (PSA) recurrence in prostatic adenocarcinoma. There have been many studies that have tried to determine an appropriate method of calculating tumor volume, but no single methodology has been agreed upon. We tested the hypothesis that the ratio of tumor positive tissue blocks to the ...

mean total dose of 0.5 per cent bupivacaine injected epiduraUy was 8.1 +0.26 ml (range 5-10 ml). The subarachnoid block usually extended from $5 to T7 dermatomes. The usual upper level of the CSE block after injection of local anaesthetic via the epidural catheter was T4. In six patients (25 per cent) the subarachnoid block reached the T4-5 level and further extension of block by epidural injec...

A detail study on the experience of agricultural extension in Nepal was done by discussion with experts, academicians and involved agricultural officers of Nepal along with review of different documents, books and articles on the subject matter. Since from the first effort of extension service, Training and visit, Integrated Rural Development Approach, Tuki Approach, Farming System Research and...

Sub-block oriented media processor architecture is presented. A block oriented instruction set extension is proposed to process and transfer 1D or 2D data blocks. Two programmable processors are employed to perform sequential processing and block oriented processing respectively. We evaluated the performance potential of the media processor architecture using a special FPGA card, and an image F...

We present a case of a middle-aged male who manifested with low-grade fever and lower back pain. MRI and bone scan of the spine were suggestive of vertebral osteomyelitis. Blood cultures were persistently positive for Enterococcus faecalis and echocardiogram revealed tricuspid valve endocarditis. There was no history of IV drug use and urine toxicology was negative. EKG showed Mobitz type II AV...

An extension to the JPEG standard (ISO/IEC DIS 10918-3) allows spatial adaptive coding of still images. As with baseline JPEG coding, one quantization matrix applies to an entire image channel, but in addition the user may specify a multiplier for each 8x8 block, which multiplies the quantization matrix, yielding the new matrix for that block. WEG 1 and 2 use much the same scheme, except there ...

Linear cryptanalysis, along with differential cryptanalysis, is an important tool to evaluate the security of block ciphers. This work introduces a novel extension of linear cryptanalysis: zero-correlation linear cryptanalysis, a technique applicable to many block cipher constructions. It is based on linear approximations with a correlation value of exactly zero. For a permutation on n bits, an...
