Optimization is essential in many scientific and economical areas, but it is often too complex to be tackled by simple straightforward calculations or by trial and error. Two well-known methods to find low-lying minima in such complex systems are simulated annealing and the genetic algorithm. In these methods artificial fluctuations control the probability of the system to overcome a local mini...

A polynomial-based division algorithm and a corresponding hardware structure are proposed. The proposed algorithm is shown to be competitive to other conventional algorithms like the Newton-Raphson algorithm for up to about 32 bits accuracy. For example, using Newton-Raphson with less than 12 bits accuracy of the initial approximation, requires 33% more general multiplications than the proposed...

The 6 = 3 × 2 huge Lie algebra Ξ of all local and non local differential operators on a circle is applied to the standard Adler-Kostant-Symes (AKS) R-bracket sckeme. It is shown in particular that there exist three additional Lie structures, associated to three graded modified classical YangBaxter(GMCYB) equations. As we know from the standard case, these structures can be used to classify in a...

This note analyzes the distribution of fixed-weight vectors obtained by the following procedure: generate a sequence of uniform random integers with a moderate number of bits; force the bottom bits of the sequence to be a standard fixed-weight vector; sort the sequence; and extract the bottom bits. This note shows, for example, that this procedure with 32-bit integers produces any particular we...

Binary descriptors of image patches are increasingly popular given that they require less storage and enable faster processing. This, however, comes at a price of lower recognition performances. To boost these performances, we project the image patches to a more discriminative subspace, and threshold their coordinates to build our binary descriptor. However, applying complex projections to the ...

OBJECTIVE The aim of this study was to assess the oral dryness in postmenopausal women and to correlate the salivary flow rate determined by sialometry with the clinical oral dryness score (CODS) obtained from Challacombe Scale. To correlate between subjective and objective oral dryness and relationship of salivary flow rate with that of the duration of menopause. MATERIALS AND METHODS Sixty ...

Objective: To examine the prevalence of mental health disorder and its related factors among Thai nurses. Material and Method: This was cross-sectional descriptive study of 390 female nurses. They were asked to complete the questionnaire which covered personal history, working conditions, job stress and general health. Multiple logistic regression was used to estimate the odds ratio (OR) for me...

Background: Internet disease management has the promise of improving care in patients with heart failure but evidence supporting its use is limited. We have designed a Heart Failure Internet Communication Tool (HFICT), allowing patients to enter messages for clinicians, as well as their daily symptoms, weight, blood pressure and heart rate. Clinicians review the information on the same day and ...

This review describes the progress of the development of surface chemical reactions for themodification of self-assembled monolayers (SAMs) and the fabrication of surface chemical gradients. Various chemical reactions can be carried out on SAMs to introduce new functionalities. “Click” reactions, which are highly efficient and selective, have largely contributed to the development and implement...
