Purpose: Real-time ultrasound is indicated for hemodialysis catheters’ insertion in internal jugular veins. We evaluated unsuccessful implantation of short-term hemodialysis catheters in internal jugular veins using real-time ultrasound between patients with and without previous short-term catheters. Methods: Observational open-label study of unsuccessful implantation of short-term hemodialysis catheters in internal jugular veins using real-time ultrasound from July 2013 to August 2014. Results: A total of 185 procedures were compared in 122 individuals; 120 (64.86%) had previously used short-term catheters. There were 5 (8%) unsuccessful implantation among 62 catheterizations without previous short-term catheter and 41 (33.6%) among 122 with previous short-term catheter (p = 0.001 Pearson’s chi-squared, odds ratio = 5.77, 95% confidence interval = 2.15–15.50, p = 0.001). Non-progressing guidewire occurred in 2 (3.2%) of 62 patients without previous short-term catheter and in 18 (14.8%) of 122 with previous short-term catheter (p = 0.018 Pearson’s chi-squared, odds ratio = 5.19, 95% confidence interval = 1.16–23.15, p = 0.031). No difference was observed between size of the veins with or without non-progressing guidewire. All 11 cases of venous thrombosis occurred in patients who had previous short-term catheter removed due to infection. Conclusion: Previous use of short-term catheter is pivotal in the occurrence of unsuccessful implantation of short-term catheter in internal jugular veins using real-time ultrasound.

Rts Game

In a real-time strategy (RTS) game, StarCraft II, players need to know the consequences before making a decision in combat. We propose a combat outcome predictor which utilizes terrain information as well as squad information. For training the model, we generated a StarCraft II combat dataset by simulating diverse and large-scale combat situations. The overall accuracy of our model was 89.7%. Our predictor can be integrated into the artificial intelligence agent for RTS games as a short-term decision-making module.

World economic aggregates are compiled infrequently and released after considerable lags. There are, however, many potentially relevant series released in a timely manner and at a higher frequency that could provide significant information about the evolution of global aggregates. The challenge is then to extract the relevant information from this multitude of indicators and combine it to track the real-time evolution of the target variables. We develop a methodology based on dynamic factor models adapted for variables with heterogeneous frequencies, ragged ends and missing data. We apply this methodology to nowcast global trade in goods in goods and services. In addition to monitoring these variables in real time, this method can also be used to obtain short-term forecasts based on the most up-to-date values of the underlying indicators.

In order to improve the prediction precision of the short-term traffic flow, a prediction method of short-term traffic flow based on cloud model was proposed. The traffic flow was fit by cloud model. The history cloud and the present cloud were built by historical traffic flow and present traffic flow. The forecast cloud is produced by both clouds. Then, combining with the volume of the short-term traffic flow of an intersection in Guangzhou City, the model was calculated and simulated through programming. Max Absolute Error (MAE) and Mean Absolute percent Error (MAPE) were used to estimate the effect of prediction. The simulation results indicate that this prediction method is effective and advanced. The change of the historical and real time traffic flow is taken into account in this method. Because the short-term traffic flow is dealt with as a whole, the error of prediction is avoided. The prediction precision and real-time prediction are satisfied.
