In recent years, we have been developing optical coherence tomography (OCT) and polarized Raman spectroscopy (PRS) for the detection of early noncavitated dental caries. OCT provides high resolution morphological depth imaging of incipient caries. With OCT, early lesions can be readily identified as regions of high light backscattering with depth into the enamel as compared to health sound enam...

BACKGROUND Data for multiple common susceptibility alleles for breast cancer may be combined to identify women at different levels of breast cancer risk. Such stratification could guide preventive and screening strategies. However, empirical evidence for genetic risk stratification is lacking. METHODS We investigated the value of using 77 breast cancer-associated single nucleotide polymorphis...

OBJECTIVES To examine the association between rice intake, staple food patterns (measured by percentage of rice in staple food (PRS)), weight change and the risk of the metabolic syndrome development. METHODS We followed 1231 adults, aged 20 and older, from 2002 to 2007. Food intake was assessed using a food frequency questionnaire. Body weight, height, waist circumference, blood pressure and...

This article treats register constraints in high performance embedded VLIW computing, aiming to decouple register constraints from instruction scheduling. It extends the register saturation (RS) concept to periodic instruction schedules, i.e., software pipelining (SWP). We formally study an approach which consists in computing the exact upper-bound of the register need for all the valid SWP sch...

This paper describes a study which used a personal response system (PRS) for formative assessment and feedback during taught sessions. The aim of the study being to see whether there was a positive impact on the students‟ final grades in the end of module summative multiple choice question assessment. Previous research into the use of a PRS demonstrated the effectiveness of the tool to increase...

Abstract Polynomial Regression Surface (PRS) is a commonly used surrogate model for its simplicity, good interpretability, and computational efficiency. The performance of PRS largely dependent on basis functions. With limited samples, how to correctly select functions remains challenging problem. To improve prediction accuracy, modeling approach based multitask optimization ensemble (PRS-MOEM)...

Platelet-rich preparations have recently gained popularity in maxillofacial and dental surgery, but their beneficial effect is still under debate. Furthermore, very little is known about the effect of platelet preparations at the cellular level, and the underlying mechanisms. In this study, we tested the effect of platelet-released supernatant (PRS) on human mesenchymal stem cell (MSC) differen...

In the past years we have witnessed an explosive growth of the data and information on the World Wide Web, which makes it difficult for normal users to find the information that they are interested in. On the other hand, the majority of the data and resources are very unpopular, which can be considered as “hidden information”, and are very difficult to find. By building a bridge between the use...
