The formation and development of large-scale structures are primary research subjects in the study of turbulent mixing layers. Visualizing these structures based on published experimental data enhances the understanding of complex flow behaviors, which is the main objective of this article. The authors employed a two-point statistical correlation method to evaluate the size of large vortex structures along the interaction region.

The study which applies quantitative methods along with the support of EVIEWS software points out a statistical significance relationship. Firstly, the CS has a contrariwise impact on ROA but no effect on ROE and ROS. Secondly, among control variables (asset structure, expenditure ratio, revenue), the expenditure ratio is the only one showing a contrariwise impact on ROS and the rest has no statistical significance.

This study aimed to assess the QoL of elderly patients with T2DM at Thai Binh Provincial General Hospital and identify associated factors influencing their QoL. Method: A total of 303 elderly patients aged 60 and above were recruited. QoL was measured using SF-36 questionnaire. Socio-demographic data, nutritional status, and comorbidities were also collected. Statistical analyses were conducted to evaluate associations between these variables and QoL scores.

The modelling of traffic flow using methods and models from physics has a long history. In recent years especially cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other hand, these systems are interesting for physicists since they allow to observe genuine nonequilibrium effects. Here the current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e.g. phase transitions) induced by on- and off-ramps.
