Shannon’s rate distortion theory demonstrates that the optimal distortion rate can be achieved by quantizing blocks of arbitrary large dimensions. In practice, however, most image compression coders rely on the principle of transform coding combined with scalar quantization and lossless coding. Transform coding consists in applying a linear transformation to an N-dimensional block of data. The ...

We give a model-independent analysis of CP violating lepton polarization in the exclusive semileptonic B decay of B → D(∗)lν̄ including dimension six four-fermion tensor interactions at the heavy quark limit. It is shown that the tensor interactions should not be neglected if the associated couplings are comparable to others. The effect of tensor interactions on the transverse lepton polarizatio...

Renal and urogenital disease is a prevalent finding of extrapulmonary Mycobacterium tuberculosis. Patients can present with unusual complaints not immediately suspicious for tuberculosis. We describe a 38-year-old man who presented with vomiting and an acute kidney injury. Imaging studies showed nodules throughout the lungs, retroperitoneum, abdominal viscera, and kidneys. Asymmetrical hydronep...

Of all the upsets which can happen to the infant or child, it would be safe to say that none is as alarming to the parents as a convulsion. A good knowledge of the causes of convulsions is therefore essential, if one is to handle the situation well, and relieve the parental anxiety with authority. The diagnosis may sometimes be difficult, for even 'windy pains ' with screaming may simulate a co...

In this paper we describe how methods of concept (classi cation) learning can be used to solve constraint satisfaction problems in the spatial domain, for example if a set of numerical constraints de nes a complicated region in the physical or feature (parameter) space. In this case it is in general not easy or even not possible to nd explicit boundary descriptions by some kind of formula manip...

Clock skew is an increasing concern for high-speed circuit designers. Circuit designers use transparent latches and skew-tolerant domino circuits to hide clock skew from the critical path and take advantage of shared portions of the clock network to budget less skew between nearby elements than across the entire die, but current timing analysis algorithms do not handle correlated clock skews. T...

Growing evidence indicates parasite inclusion in food-web analyses is a logical default. Comparisons of food webs including and excluding host-parasite interactions demonstrate the influence of parasites on community dynamics. Although including parasites is undoubtedly informative, the necessary level of detail exists for only a handful of systems. In a recent Ecology Letters article, Lafferty...

CASSCF/MRCI/aug-cc-pVQZ~no g! and RCCSD~T!/aug-cc-pVQZ potential energy functions were reported for the à B1 and X̃ A1 states of CF2 , respectively. Vibrational wave functions of the symmetric stretching and bending modes of the two states of CF2 were obtained in variational calculations, employing Watson’s Hamiltonian for a nonlinear molecule and anharmonic vibrational wave functions expressed ...

This paper reviews major issues in the implementation of e-manufacturing, particularly the design aspects. It will examine recent progress, drawing out particular issues that are being addressed. Use will be made of the work by the author and colleagues to devise rule-based design and Internet-based control of machines to illustrate how these developments affect the integrated e-manufacturing e...
