There are two main approaches, conservative and optimistic, for maintaining consistency in distributed network games. Under the conservative approach, players may experience network latency, depending on packet transfer delay caused by the send-and-wait and acknowledging processes. Under the optimistic approach, the processes do not wait for other players’ packets and advance to their own frame...

Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...

BACKGROUND Obstructive sleep apnea (OSA) is a major risk factor for perioperative adverse events. However, no screening tool for OSA has been validated in surgical patients. This study was conducted to develop and validate a concise and easy-to-use questionnaire for OSA screening in surgical patients. METHODS After hospital ethics approval, preoperative patients aged 18 yr or older and withou...

Recent research has demonstrated that minority drivers receive disparate traffic stop outcomes compared with similarly situated White drivers. This research, however, is often not grounded within a theoretical framework and fails to examine specific combinations of driver demographics. This study addresses those shortcomings by examining research questions based on the social conditioning model...

conclusions: premature stop codon in the s gene was observed in all countries with evaluable hbv genome sequences. co-existence of detectable hepatitis b surface antigen (hbsag) and s gene premature stop codon was inconsistent with other studies. investigations on yield truncated hbsag are suggested to determine if they can affect elisa hbsag results. background: we have previously reported on ...
