Aiming at solving the fusion problem of multifocus, a novel image fusion algorithm is presented in this paper. Firstly, the multiwavelet is combined with the direction filter bank (DFB) to construct the proposed MDFB transform to overcome defect of the contourlet transform. Secondly, the source multifocus images are decomposed into lowpass coefficients and highpass coefficients. Thirdly, the lo...

1. Iron spicules found in the brains of general paretic patients are formed from endogenous brain iron normally present in another form. This supports our earlier view that the micro value of 16,000 obtained in advanced paretics for alpha brain wave frequencies as a measure of cortical respiration comes about from the slowing of an iron catalyzed link in cortical respiration such as would resul...

Recently, focus on maintenance strategies has been shifted towards prognostic health management (PHM) and a number of state of the art algorithms based on data-driven prognostics have been developed to predict the health states of degrading components based on sensory data. Amongst these algorithms, Multiclass Support Vector Machines (MC-SVM) has gained popularity due to its relatively high cla...

A chemical active medium on the base of Belousov-Zhabotinsky (BZ) medium was used to design a “chemical diode”. This system, similar to a semiconductor diode, shows unidirectional propagation of chemical pulses and may be possible to be used to construct a massively parallel computational medium. The system of two mesoporous glass plates with ferroin loaded at the surface was covered by BZ solu...

Some authors in fact refer to episodes as chemical arachnoiditis. Jolles et al. at the National Institute for Medical Research, London, ( [1] ) discussed Drug-induced aseptic meningitis (DIAM), which they denoted as "uncommon." The authors remarked that most of the literature comprises anecdotal case reports. The major types of causative drugs are nonsteroidal anti-inflammatory drugs ...

An attempt to condense the important knowledge in a broad field into a small volume is fraught with danger. It is particularly hazardous when the field at issue is one which straddles two established disciplines such as biochemistry and microbiology. A. H. Rose is aware of the problems inherent in his task, and it is probably due in no small part to this awareness that he brings it off so well....

We show how to include a chemical potential µ in perfect lattice actions. It turns out that the standard procedure of multiplying the quark fields Ψ, ¯ Ψ at Euclidean time t by exp(±µt), respectively, is perfect. As an example, the case of free fermions with chemical potential is worked out explicitly. Even after truncation, cutoff effects in the pressure and the baryon density are small. Using...

Chemical Cocktails Are Mixed Pesticides More Potent? Increasing evidence suggests that environmental chemicals that interact with the endocrine system harm the health of humans and animals. More recent studies suggest further that these chemicals act synergistically, meaning that their combined effect is greater than the sum of their individual effects. While few scientists doubt that endocrine...
