1A Hybrid Forecasting Framework Based on Support Vector Regression with a Modified Genetic Algorithm and a Random Forest for Traffic Flow Prediction显示文摘The ability to perform short-term traffic flow forecasting is a crucial component of intelligent transportation systems. However, accurate and reliable traffic flow forecasting is still a significant issue due to the complexity and variability of real traffic systems. To improve the accuracy of short-term traffic flow forecasting, this paper presents a novel hybrid prediction framework based on Support Vector Regression(SVR) that uses a Random Forest(RF) to select the most informative feature subset and an enhanced Genetic Algorithm(GA) with chaotic characteristics to identify the optimal forecasting model parameters. The framework is evaluated with real-world traffic data collected from eight sensors located near the I-605 interstate highway in California. Results show that the proposed RFCGASVR model achieves better performance than other methods.Lizong Zhang Nawaf R Alharbe Guangchun Luo Zhiyuan Yao Ying Li 2018Tsinghua Science and Technology2018,23,4:19
2Use of scoring systems for assessing and reporting the outcome results from shoulder surgery and arthroplasty显示文摘To investigate shoulder scoring systems used in Europe and North America and how outcomes might be classified after shoulder joint replacement. All research papers published in four major journals in 2012 and 2013 were reviewed for the shoulder scoring systems used in their published papers. A method of identifying how outcomes after shoulder arthroplasty might be used to categorize patients into fair, good, very good and excellent outcomes was explored using the outcome evaluations from patients treated in our own unit. A total of 174 research articles that were published in the four journals used some form of shoulder scoring system. The outcome from shoulder arthroplasty in our unit has been evaluated using the constant score(CS) and the oxford shoulder score and these scores have been used to evaluate individual patient outcomes. CSs of < 30 = unsatisfactory; 30-39 = fair; 40-59 = good; 60-69 = very good; and 70 and over = excellent. The most popular shoulder scoring systems in North America were Simple Shoulder Test and American shoulder and elbow surgeons standard shoulder assessment form score and in Europe CS, Oxford Shoulder Score and DASH score.Simon Booker Nawaf Alfahad Martin Scott Ben Gooding W Angus Wallace 2015World Journal of Orthopedics2015,6,2:5

4Gastric malignancies in Northern Jordan with special emphasis on descriptive epidemiology显示文摘AIM: To study the epidemiology of gastric malignancies in Jordan as a model for Middle East countries where such data is scarce.METHODS: Pertinent epidemiological and clinicopathological data for 201 patients with gastric malignancy in north of Jordan between 1991 and 2001 were analyzed.RESULTS: Male: female ratio was 1.8:1. The mean age was 61.2 years, and 8.5% of the patients were younger than 40 years of age. The overall age-adjusted incidence was 5.82/100 000 population/year. The age specific incidence for males raised from 1.48 in those aged 30-39 years to 72.4 in those aged 70-79 years. Adenocarcinomas,gastric lymphomas, malignant stromal tumors, and carcinoids were found in 87.5%, 8%, 2.5%, and 2% respectively. There was an average of 10.1-month delay between the initial symptoms and the diagnosis. Only 82 patients underwent 'curative' gastrectomy. Among adenocarcinoma groups, Lauren intestinal type was the commonest (72.2%) and the distal third was the most common localization (48.9%). The mean follow up for patients with gastric adenocarcinoma was 25.1 mo (range 1-132 mo). The 5-year survival rates for stages Ⅰ (n=15),Ⅱ(n=41), Ⅲ (n=59), and Ⅳ (n=53) were 67.3%, 41.3%,5.7%, and 0% respectively (P=0.0001). The overall 5 year survival was 21.1%.CONCLUSION: Despite low incidence, some epidemiological features of gastric cancer in Jordan mimic those of highrisk areas. Patients are detected and treated after a relatively long delay. No justification in favor of a possibleg astric cancer screening effort in Jordan is supported byour study; rather, the need of an earlier diagnosis andsubsequent better care.Kamal E.Bani-Hani Rami J.Yaghan Hussein A.Heis Nawaf J.Shatnawi Ismail I.Matalka Amjad M.Bani-Hani Kamal A.Gharaibeh 2004World Journal of Gastroenterology2004,10,15:4
5Performance of American Society for Gastrointestinal Endoscopy guidelines for dyspepsia in Saudi population: Prospective observational study显示文摘AIM: To evaluate adherence of primary care physicians(PCPs) to international guidelines when referring patients for upper-gastrointestinal endoscopy(UGE), evaluate the importance of alarm symptoms and the performance of the American Society for Gastrointestinal Endoscopy(ASGE) guidelines in a Saudi population.METHODS: A prospective, observational cross-sectional study on dyspeptic patients undergoing UGE who were referred by PCPs over a 4 mo period. Refer-rals were classified as appropriate or inappropriate according to adherence to ASGE guidelines.RESULTS: Total of 221 dyspeptic patients was enrolled; 161 patients met our inclusion criteria. Mean age was 40.3 years(SD ± 18.1). Females comprised 70.1%. Alarm symptoms included low hemoglobin level(39%), weight loss(18%), vomiting(16%), loss of appetite(16%), difficulty swallowing(3%), and gastrointestinal bleeding(3%). Abnormal endoscopy findings included gastritis(52%), duodenitis(10%), hiatus hernia(7.8%), features suggestive of celiac disease(6.5%), ulcers(3.9%), malignancy(2.6%) and gastroesophageal reflux disease(GERD: 17%). Among patients who underwent UGE, 63% met ASGE guidelines, and 50% had abnormal endoscopic findings. Endoscopy was not indicated in remaining 37% of patients. Among the latter group, endoscopy was normal in 54% of patients. There was no difference in proportion of abnormal endoscopic findings between two groups(P = 0.639).CONCLUSION: Dyspeptic patients had a low prevalence of important endoscopic lesions, and none of the alarm symptoms could significantly predict abnormalendoscopic findings.Nahla A Azzam Majid A Almadi Hessah Hamad Alamar Lamis Atyah Almalki Rehab Nawaf Alrashedi Rawabi Saleh Alghamdi Waleed Al-hamoudi 2015World Journal of Gastroenterology2015,21,2:2

8Tranexamic acid for intracerebral haemorrhage within 2 hours of onset: protocol of a phase Ⅱ randomised placebo-controlled double-blind multicentre trial显示文摘Rationale Haematoma growth is common early after intracerebral haemorrhage(ICH),and is a key determinant of outcome.Tranexamic acid,a widely available antifibrinolytic agent with an excellent safety profile,may reduce haematoma growth.Methods and design Stopping intracerebral haemorrhage with tranexamic acid for hyperacute onset presentation including mobile stroke units(STOP-MSU)is a phase Ⅱ double-blind,randomised,placebo-controlled,multicentre,international investigator-led clinical trial,conducted within the estimand statistical framework.Hypothesis In patients with spontaneous ICH,treatment with tranexamic acid within 2 hours of onset will reduce haematoma expansion compared with placebo.Sample size estimates A sample size of 180 patients(90 in each arm)would be required to detect an absolute difference in the primary outcome of 20%(placebo 39%vs treatment 19%)under a two-tailed significance level of 0.05.An adaptive sample size re-estimation based on the outcomes of 144 patients will allow a possible increase to a prespecified maximum of 326 patients.Intervention Participants will receive 1 g intravenous tranexamic acid over 10 min,followed by 1 g intravenous tranexamic acid over 8 hours;or matching placebo.Primary efficacy measure The primary efficacy measure is the proportion of patients with haematoma growth by 24±6 hours,defined as either≥33%relative increase or≥6 mL absolute increase in haematoma volume between baseline and follow-up CT scan.Discussion We describe the rationale and protocol of STOP-MSU,a phase Ⅱ trial of tranexamic acid in patients with ICH within 2 hours from onset,based in participating mobile stroke units and emergency departments.Nawaf Yassi Henry Zhao Leonid Churilov Bruce C V Campbell Teddy Wu Henry Ma Andrew Cheung Timothy Kleinig Helen Brown Philip Choi Jiann-Shing Jeng Annemarei Ranta Hao-Kuang Wang Geoffrey C Cloud Rohan Grimley Darshan Shah Neil Spratt Der-Yang Cho Karim Mahawish Lauren Sanders John Worthington Ben Clissold Atte Meretoja Vignan Yogendrakumar Mai Duy Ton Duc Phuc Dang Nguyen Thai My Phuong Huy-Thang Nguyen Chung Y Hsu Gagan Sharma Peter J Mitchell Bernard Yan Mark W Parsons Christopher Levi Geoffrey A Donnan Stephen M Davis 2022Stroke & Vascular Neurology2022,7,2:1
