OBJECTIVE At present, the evidence regarding the type of mattress that is the best for preventing pressure ulcers is not convincing. In a single center, prospective, controlled trial we compared a static air overlay mattress (no electric pump needed) on top of a cold foam mattress with a cold foam mattress alone on pressure ulcer incidence in nursing home residents. METHODS 83 Patients were i...

Diagnosis exercise plays an important role in developing educational plans. It is the diagnosis through which the main problems are identified and areas and focus groups that need attention are known. A variety of information is required to undertake rigorous diagnosis exercise. The data in its original form cannot be used to draw inferences. It needs to be converted in the form of indicators s...

For solving the uncertain parameter selection, the highly spatiotemporal complexity and the difficulty of effectively extracting feature in manifold learning algorithm processing higher-dimension of human action sequence, human action recognition algorithm based on random spectral regression (RSPR) is presented. The algorithm has three steps. Firstly, according to uniform distribution of human ...

We have studied the group and phase speed structure of long-range acoustic arrivals using linear acoustics. Here we present a preliminary study of some of these same paths but now we consider a higher amplitude source necessitating a nonlinear acoustic treatment. This research involves the eventual coupling of the Nonlinear Progressive Wave Equation (NPE) with an Adiabatic Normal Mode (ANM) Mod...


 The Norton product is defined on each eigenspace of a distance regular graph by the orthogonal projection entry-wise product. resulting algebra, known as commutative nonassociative algebra that useful in group theory due to its interesting automorphism group. We provide formula for Hamming using linear characters. construct large subgroup automorphisms and completely describe some cases....

This paper presents FPE (Formatpreserving Encryption) for character data in both fixed-width and variable-width encoding. Previous researches only studied FPE for fixed-width character data. In this paper, FPE for character data is categorized into NPE (Number-preserving Encryption) and LPE (Length-preserving Encryption). The schemes related to NPE and LPE are proposed to encrypt fixed-width an...

Flexocleaners.com and The Sierra Club urge the Environmental Protection Agency (EPA), state agencies and corporations to eliminate the use of the cleaning agent, nonylphenol ethoxylates (NPEs), in the industrial and domestic laundry detergent used in the United States. NPE metabolites often pass through wastewater treatment plants at a concentration that has been shown to cause harmful effects ...

In this paper, a novel supervised feature extraction and classification fusion algorithm based on neighborhood preserving embedding (NPE) and sparse representation is proposed. Specifically, an optimal dictionary is adaptively learned to bate the trivial information of the original training data; then, in order to obtain the sparse representation coefficients, a sparse preserving embedding map ...
