In our paper at OOPSLA 2003 we discussed the design and implementation of a new atomic keyword as an extension to the Java programming language. It allows programs to perform a series of heap accesses atomically without needing to use mutual exclusion locks. We showed that data structures built using it could perform well and scale to large multi-processor systems. In this paper we extend our s...

Integral distinguisher is the main factor of integral attack. Conventionally, higher order integral distinguisher is obtained as an extension of first order integral (conventional algorithm). The algorithm was applied to many subblock-based block ciphers, however, the conventional algorithm has some problems. We find other integral distinguisher of two sub block-based block ciphers, TWINE and L...

The IEEE 802.11e standard extension for medium access control protocol in wireless local area networks enhances the existing IEEE 802.11 protocol specification towards support for quality of service and improved spectrum management. We look in this paper specifically into an 802.11e concept that is referred to as block acknowledgment. Unlike the original 802.11, where every frame reception must...

Six hemiparetic stroke patients presenting with a stiff-legged gait underwent a motor branch block of rectus femoris (RF). A gait analysis, including synchronous kinematic, dynamic, energetic recordings was performed before and after motor branch block of RF. The electrical activity of RF, Vastus Medialis, Vastus Lateralis, Vastus Intermedius was also recorded. Before nerve block, the sagittal ...

Block-oriented signal processing techniques have exceptional role due to the availability of fast algorithms. However , if larger data segments are to be evaluated in real-time, the delay caused by the block-oriented approach is not always tolerable especially if the response time of our evaluating system is also specied. This can be exceptionally critical if the signal processing is related to...

| This paper presents a new VLSI architecture of the Motion Estimation in MPEG-2. Previously , a number of full search block matching algorithms (BMA) and architectures using systolic array have been proposed for motion estimation. However, the architectures have an ineeciently large number of external memory access. Recently, to reduce the number of accesses in one candidate block, a block mat...

<p class="abstract">Proximal radio ulnar synostosis is a rare entity presenting with restriction of supination and pronation. Among the various types, type 4 variety even more-rare its presentation, can pose diagnostic challenge specially, if history trauma. Radiologically, it usually overlooked as malunited radial neck therefore needs thorough evaluation. We presented case 15-year-old ma...
