Contact dermatitis is an inflammatory skin disease due to contact with different substances and caused by two mechanisms: Allergy and irritation. Contact dermatitis is a common skin disease and the most common occupational dermatosis. Differentiating between allergic and irritant contact dermatitis is essential in the identification of etiologic factor(s) and hence, its control and prognosis. T...

Asthma affects a significant proportion of elderly patients, but unfortunately, it is responsible for a high asthma-related morbidity and mortality in this population. This may be related not only to the development of a more severe asthma phenotype compared to younger patients, with more marked airway obstruction and a more neutrophilic type of airway inflammation, but also to the presence of ...

One frequently needs to compare the performance of two or more parallel computers; but how should this be done? The most straightforward way to do this would be to rely upon a suite of benchmarks. Unfortunately, there are many problems and limitations with this approach. Therefore, one is frequently forced to rely upon a combination of approaches. Unfortunately, many of the alternative approach...

This paper deals with the security and efficiency issues of a cryptographic algorithm which utilizes the principles of Chaotic Neural Network (CNN). The algorithm that we consider is the Delayed CNNBased Encryption (DCBE), which is an encryption algorithm based on the Delayed CNN. Although the cryptographic algorithm has its own salient characteristics, our analysis show that, unfortunately, th...

Sand-swimming, a form of desert burrowing, offers interesting potential as a locomotion mode for robots operating in loose, granular environments. Unfortunately, the computational cost of modeling the relevant physics raises obstacles to a thorough exploration of the system dynamics. Geometric mechanics offers techniques for reducing the complexity of evaluating gaits, thereby offering the pote...

Multilingual computing is going to dominate the next era of Information Technology. Many Multilingual products are available in the market today. But, unfortunately most of the products are font based and not language based. We know that the E-mail facility is now being used extensively. But, unfortunately the usage of E-mail is limited within the people who know English. Even though some E-mai...

Unfortunately, first-order implementations lead to inaccuracies in computed traveltimes, which may lead to poor image focusing for migration applications. In addition, first-order traveltimes are not accurate enough for reliable amplitude calculations. This has lead to the development of the fast marching method on non-Cartesian (Alkhalifah and Fomel, 1997; Sun and Fomel, 1998), and even unstru...

Considerable progress has been made in the treatment of infections in neutropenic patients during the past three decades. A major contribution to this progress has been the discovery of effective new therapies and their prompt administration. Unfortunately, successful therapy of each important pathogen has resulted in the emergence of new pathogens, usually with unique patterns of antibiotic su...
