Superior Vena Cava Syndrome (SVCS) is caused by gradual compression of the Superior Vena Cava (SVC), a major vessel in the superior mediastinum that collects venous return to the heart from the head, arms and the upper torso [1]. In clinical practice, SVCS is predominantly associated with malignancies that cause extrinsic compression. The commonly documented malignancies are lung carcinoma and ...

In this paper we introduce dictionary-symbolwise data compression schemes. We describe a method that, under some natural hypothesis, allows to obtain an optimal parse of any input or of any part of an input. This method can also be used to approximate the optimal parse in the general case and, under some additional hypothesis, it gives rise to on-line data compression algorithms. Therefore it c...

This paper addresses the problem of low memory wavelet image compression. While wavelet or subband coding of images has been shown to be superior to more traditional transform coding techniques, little attention has been paid until recently to the important issue of whether both the wavelet transforms and the subsequent coding can be implemented in low memory without significant loss in perform...

SPIHT (Set Partitioning In hierachical trees), being an efficient coding method for wavelet coefficients, has acquired more and more widely application, especially in image/video compression fields. But, conventional SPHIT have some obvious limitions. For example, when for the color image compression, polarmetric SAR image compression, or multispectrum image compression and other multi-channel ...

The encoding of image partitions plays a key role in the overall efficiency of the so-called region-based image coding techniques. Recently, a method based on the novel concept of “transition point” was proposed for the lossless encoding of arbitrary contour maps. This paper addresses the problem of partition simplification in the context of this new encoding method. A new simplification approa...

background: phic31 integrase is a dna site-specific recombinase integrates dna into the chromosomes between the two sites of attb and attp. several pseudo attps have been identified in mammalian genomes with critical features for long-term expression of transgene. in this manuscript, we report a novel intrinsic pseudo attp site named chol1 in the chinese hamster genome implementing an inverse p...

operating an engine with homogeneous charge compression ignition (hcci) technique is a promising technique to lower nox and pm emissions of engines while achieving high efficiency and lower fuel consumption. nevertheless, applications for hcci are still limited due to the absence of a definite means to control ignition timing and narrow operating region. a single cylinder diesel engine with com...

The peak power delivered by the klystrons in the NLCTA (Next Linear Collider Test Accelerator) now under construction at SLAC is enhanced by a factor of four in a SLED-II type of R.F. pulse compression system (pulse width compression ratio of six). To achieve the desired output pulse duration of 250 ns, a delay line constructed from a 36 m length of circular waveguide is used. Future colliders,...

Advanced brain-chip interfaces with numerous recording sites bear great potential for investigation of neuroprosthetic applications. The bottleneck towards achieving an efficient bio-electronic link is the real-time processing of neuronal signals, which imposes excessive requirements on bandwidth, energy and computation capacity. Here we present a unique concept where the intrinsic properties o...
