In this paper we cluster and analyse temporal user behaviour in online communities. We adapt a simple unsupervised clustering algorithm to an evolutionary setting where we cluster users into prototypical behavioural roles based on features derived from their ego-centric reply-graphs. We then analyse changes in the role membership of the users over time, the change in role composition of forums ...

Takayasu arteritis (TA) is a chronic large-vessel vasculitis of unclear pathogenesis. A recent genome-wide association study (GWAS) has revealed that the FCGR2A/FCGR3A, EEFSEC, RPS9/LILRB3, RIPPLY2 and MLX genes confer susceptibility to TA. We investigated the linkage between presumptive TA-related genes (FCGR2A/FCGR3A, EEFSEC, RPS9/LILRB3, RIPPLY2 and MLX) and TA in the Han Chinese population....

We consider the security of Identity-Based Encryption (IBE) in the setting of multiple Trusted Authorities (TAs). In this multi-TA setting, we envisage multiple TAs sharing some common parameters, but each TA generating its own master secrets and master public keys. We provide security notions and security models for the multi-TA setting which can be seen as natural extensions of existing notio...

OBJECTIVES The aim was to compare continuous and on-demand NSAID treatment with respect to their ability to suppress radiographic progression in subgroups of patients with high/elevated CRP-levels, ESR, ASDAS-levels or BASDAI-levels in comparison to patients with normal levels. METHODS Post-hoc analyses were performed in a randomized trial comparing continuous and on-demand NSAID treatment. R...

BACKGROUND In recent years, catheter ablation has increasingly been used for ablation of idiopathic premature ventricular complexes (PVCs) or ventricular tachycardias (IVTs). However, the mapping and catheter ablation of the arrhythmias originating from the vicinity of tricuspid annulus (TA) may not be fully understood. This study aimed to investigate electrophysiologic characteristics and effe...

The present research aims to design strategic management model in technical and vocational training. The research has qualitative design and for data analysis and classification, thematic Analysis Method (Thematic Network) was applied. The statistical population of the study consisted of experts of the Iran Technical and Vocational Training Organization. The number of 13 participants were selec...

We investigate reachability (or equivalently, safety) for timed systems modelled as Timed Automata (TA) under notions of “robustness”, i.e., when the clocks of the TA may drift by small amounts. Our contributions are two-fold: (1) We first consider the model of clock-drift introduced by Puri [1] and subsequently studied in other works [2, 3, 4]. We show that the standard zone-based forward reac...

The importance rating of the technical skills and their related knowledge of industrial engineering and business management graduates are developed. A survey was conducted at the Faculty of Economics of the Budapest Tech to measure and evaluate 17 technical skills required by employers. The study utilized questionnaires to rate and rank these skills based on student assessment. The research was...

OBJECTIVE We analyzed the concordance between two methods for measuring treatment adherence (TA) and studied the determinants of TA in patients with type 2 diabetes mellitus. METHODS We conducted a cross-sectional descriptive study in a primary care center, involving 320 diabetic patients. TA was measured using the Haynes-Sackett (H-S) adherence test during the patient interview and based on ...
