OMICS data are increasingly available to biomedical researchers, and (biological) replications are more and more affordable for gene microarray experiments or proteomics experiments. The functional relationship between a pair of genes or proteins are often inferred by calculating correlation coefficient between their expression profiles. Classical correlation estimation techniques, such as Pear...

The purpose of this study was to determine if a pharmacology medical history assignment would enable dental students to demonstrate improved knowledge and understanding of pharmacology by researching the drugs their patients were taking and recording pharmacological information in their patients' health records. The study followed a pretest-posttest design and evaluated students' knowledge of t...

the current study examined interrelation of affectivity, emotional intelligence and personality and their roles in sport coaches’ transformational leadership style using their disposition. data are collected from 206 sport coaches. pearson correlation coefficient was used to analyze data. the results showed a positive deep relationship between positive affectivity with personality (r=0.251, p

It is widely appreciated that many studies in psychological science suffer from low statistical power. One of the consequences analyzing underpowered with thresholds significance a high risk finding exaggerated effect size estimates, right or wrong direction. These inferential risks can be directly quantified terms Type M (magnitude) error and S (sign) error, which communicate design choices on...

Background. Protein dihedral angles provide a detailed description of protein local conformation. Predicted dihedral angles can be used to narrow down the conformational space of the whole polypeptide chain significantly, thus aiding protein tertiary structure prediction. However, direct angle prediction from sequence alone is challenging. Method. In this study, we present a novel method to pre...

A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the...

BACKGROUND Assessment of treatment response by measuring tumor size is known to be a late and potentially confounded response index. Serial diffusion MRI has shown potential for allowing earlier and possibly more reliable response assessment in adult patients, with limited experience in clinical settings and in pediatric brain cancer. We present a retrospective study of clinical MRI data in chi...

In this paper, the predictive capability of surface and untargeted intramuscular electromyography (EMG) was compared with respect to wrist-joint torque to quantify which type of measurement better represents joint torque during multiple degrees-of-freedom (DoF) movements for possible application in prosthetic control. Ten able-bodied subjects participated in the study. Surface and intramuscular...

BACKGROUND One of the most immediate and important functional consequences of many oral disorders is a reduction in chewing ability. The ability to chew is not only an important dimension of oral health, but is increasingly recognized as being associated with general health status. Whether perceived chewing ability and oral health-related quality of life (OHRQoL) are correlated to a similar deg...
