In this paper, we studied the global dynamics of a SEIR epidemic model in which the latent and immune state were infective. The basic reproductive rate, R0, is derived. If R0 6 1, the disease-free equilibrium is globally stable and the disease always dies out. If R0 > 1, there exists a unique endemic equilibrium which is locally stable. Furthermore, we proved the global stability of the unique ...

The purpose of this article is to articulate and provide detail about an interprofessional research collaboration at a public university in a rural area of western United States. This interprofessional research collaboration was organized to explore infant and maternal reciprocity. As a part of the organization and process portion of the collaborative effort, the authors identify the unique att...

This article provides an overview of the current development of information and communication technology (ICT) utilized in Chinese education since China joined the World Trade Organization (WTO). Specifically, the article describes and discusses the positive impacts ICT has on Chinese basic education (grade one to grade nine), as well as the existing problems in the application of ICT. The arti...

Patents do not always promote innovation, particularly when they restrict access to fundamental scientific discoveries and the tools of basic research. However, there are legal and policy approaches that may help to ameliorate problems associated with patenting these sorts of inventions.

Total protein content is a measurement common to many applications in basic science and clinical research. Several different fluorescent techniques are available that eliminate many of the problems associated with the traditional absorbance-based colorimetric methods to measure total protein content. Here we describe the use of fluorescamine to quantitate total protein using the BioTek FL600 fl...

In this paper we propose a new approach for the generation of visual scales for the visualization of scalar and multivariate data. Based on the speci cation of only a few correspondences between the data set and elements of a space of visual representations complex visualization mappings are produced. The foundation of this approach is the introduction of a multidimensional space of visual repr...

A n Internet search using the words healing and transformation leads one to many alternative and complementary therapy sites. Similarly, when examining scientific databases relatively little comes up. Has the focus on basic science, randomized clinical trials, and numbers needed to treat jettisoned the less measurable aspects of clinical practice, such as the patient-healer relationship, into t...

The present document aims at providing a short, didactical introduction to three standard versions of the Kalman filter, namely its variants identified as Basic, Extended , and Unscented. The application of these algorithms in three representative problems is discussed.

In the video indexing framework, we have developed a user assistance system in order to define concept models (i.e semantic index) according to features automatically extracted from the video. Because the manual indexing is a long and tedious task, we propose to focus the user attention on pre-selected prototypes that a priori correspond to the searched concepts. The proposed system is decompos...
