While it is difficult to devise human-computer interfaces which work well, it is even more difficult to determine why a good interface is good. In programming and database query languages, many human factors experiments have been performed. These experiments have led to little hard knowledge about the nature of learnin... |
Abstract: Sliding mode control is a very attractive control scheme because of its robustness against modelling imperfections and external disturbances. It has been successfully employed to the dynamic positioning of remotely operated underwater vehicles. In such situations, the discontinuities in the control law must b... |
In the past, scholars of academic dependency have tended to focus their discussions on social sciences while treating other fields as separate. They suggest that in order to escape dependency, alternative discourse and autonomy should be developed. In this paper, we examine the Public Health Liberation (PHL) movement i... |

BACKGROUND |
Precision prevention is increasingly important in HIV prevention research to move beyond universal interventions to those tailored for high-risk individuals. The current study was designed to develop machine learning algorithms for predicting adolescent HIV risk behaviours. |
METHODS |
Comprehensive longitudinal data on adolescent risk behaviours, perceptions, peer and family influence, and neighbourhood risk factors were collected from 2564 grade-10 students at baseline followed for 24 months over 2008-2012. Machine learning techniques [support vector machine (SVM) and random forests] were applied t... |
RESULTS |
The SVM model with cost-sensitive learning achieved the highest sensitivity, at 79.1%, specificity of 75.4% with AUC of 0.86 in predicting multiple sex partners on the training data (10-fold cross-validation), and sensitivity of 79.7%, specificity of 76.5% with AUC of 0.86 on the testing data. The random forest model o... |
CONCLUSION |
Machine learning methods can be used to build effective prediction model(s) to identify adolescents who are likely to engage in HIV risk behaviours. This study builds a foundation for targeted intervention strategies and informs precision prevention efforts in school-setting.[Fine-structure and function of the primary ... |
Results obtained by mechanical isolation of neuroblasts from the primary proliferative layer of the central nervous system in chick embryos by the aid of an original method and by electronmicroscopic investigations are consistent with Sauer's concept on neuroepithelial cell proliferation. The bipolar form of the undiff... |
Calcium phosphate (Ca-P) coating on the Ti-6Al-4V alloy enhances osteoblast adhesion and tissue formation at the bone implant interface. In light of this, in the current work a laser-based coating technique was used to synthesize two different micro-textured (100 µm and 200 µm spaced line patterns) Ca-P coatings on the... |

Atrial fibrillation (AF) is frequently observed in hypertrophic cardiomyopathy (HCM) and is associated with poor clinical outcome. Total atrial conduction time, estimated by tissue Doppler imaging (TDI), the so-called PA-TDI duration, reflects the left atrial (LA) structural and electrical remodelling. The aim of this ... |
METHODS AND RESULTS |
From a large cohort of patients with HCM, 208 patients (64% male, mean age 53 ± 14 years) without AF were selected. PA-TDI duration was measured from the onset P wave on electrocardiogram to the peak A' wave of the lateral LA wall using TDI. The incidence of new-onset AF was 20% over a median follow-up of 7.3 (3.5-10.5... |
