| 1 | Nonlinear Measurement Function in the Ensemble Kalman Filter显示文摘The optimal Kalman gain was analyzed in a rigorous statistical framework. Emphasis was placed on a comprehensive understanding and interpretation of the current algorithm, especially when the measurement function is nonlinear. It is argued that when the measurement function is nonlinear, the current ensemble Kalman Filter algorithm seems to contain implicit assumptions: the forecast of the measurement function is unbiased or the nonlinear measurement function is linearized.While the forecast of the model state is assumed to be unbiased, the two assumptions are actually equivalent.On the above basis, we present two modified Kalman gain algorithms. Compared to the current Kalman gain algorithm,the modified ones remove the above assumptions, thereby leading to smaller estimated errors. This outcome was confirmed experimentally, in which we used the simple Lorenz 3-component model as the test-bed. It was found that in such a simple nonlinear dynamical system, the modified Kalman gain can perform better than the current one. However, the application of the modified schemes to realistic models involving nonlinear measurement functions needs to be further investigated. | Youmin TANG Jaison AMBANDAN Dake CHEN | 2014 | Advances in Atmospheric Sciences2014，31，3： | 2 |

| 11 | Drug utilization evaluation of medications used in the management of neurological disorders显示文摘Background and object:The burden of neurological disorders in India is expected to increase due to the rapid demographic and epidemiological transition,with irrational drug use,which is also a global concern.Thus,drug utilization evaluation is designed to ensure appropriate medicine use within the healthcare settings.The aim of the study was to assess the rate and pattern of drug utilization in the management of neurological disorders.Materials and methods:A hospital-based cross-sectional drug utilization evaluation study on neurological drugs was carried out at the Department of Neurology over a span of six months.All legible prescriptions consisting neurological medications irrespective of patient's gender,aged≥18 years were included for the study.The World Health Organization(WHO)core drug use indicators were used to assess the drug prescribing and utilization patterns.Results:A total of 310 prescriptions were reviewed,where male predominance was found to be 56.45%.Out of 310 prescriptions,drugs belonging to 26 neurological classes were prescribed for the management of various neurological disorders.The majority of patients were diagnosed with epilepsy and the most prescribed drugs per patient were phenytoin(14.8%)and valproic acid(6.45%).By following the WHO core drug prescribing indicators,65.47%of drugs prescribed from the India National List of Essential Medicines,2022,followed by 29.83%of drugs prescribed in generic name and 10.86%of prescriptions including injections.Conclusion:The study findings showed that the prescribing pattern in the Department of Neurology was in accordance with the WHO core prescribing indicators.But,the extent of polypharmacy prescriptions was very high.Therefore,interventions are very necessary to promote rational drug prescribing patterns and thus clinical pharmacists can contribute to assess and review the drug utilization pattern to optimize the drug therapy and improvement in patient safety. | Meghana Upadhya Nivya Jimmy Jesslyn Maria Jaison Shahal Sidheque Harsha Sundaramurthy Nemichandra S c Shasthara Paneyala Madhan Ramesh Jehath Syed Nikita Pal Sri Harsha Chalasani | 2023 | Global Health Journal2023，7，3： | 1 |

| 17 | Prevalence of internet addiction among college students in the Indian setting:a systematic review and meta-analysis显示文摘Background The internet is an integral part of everyone’s life.College going adolescents are highly vulnerable to the misuse of the internet.Aims To estimate the pooled prevalence of internet addiction(IA)among college students in India.Methods Literature databases(PubMed,Web of Science,Scopus,EMBASE,PsycINFO and Google Scholar)were searched for studies assessing IA using the Young Internet Addiction Test(Y-IAT)among adolescents from India,published in the English language up to December 2020.We included studies from 2010 to 2020 as this is the marked era of momentum in wireless internet connectivity in India.The methodological quality of each study was scored,and data were extracted from the published reports.Pooled prevalence was estimated using the fixed-effects model.Publication bias was evaluated using Egger’s test and visual inspection of the symmetry in funnel plots.Results Fifty studies conducted in 19 states of India estimated the prevalence of IA and the overall prevalence of IA as 19.9%(95%CI:19.3%to 20.5%)and 40.7%(95%CI:38.7%to 42.8%)based on the Y-IAT cut-off scores of 50 and 40,respectively.The estimated prevalence of severe IA was significantly higher in the Y-IAT cut-off points of 70 than 80(12.7%(95%CI:11.2%to 14.3%)vs 4.6%(95%CI:4.1%to 5.2%)).The sampling method and quality of included studies had a significant effect on the estimation of prevalence in which studies using non-probability sampling and low risk of bias(total quality score≥7)reported lower prevalence.The overall quality of evidence was rated as‘moderate’based on the Grading of Recommendations Assessment,Development and Evaluation criteria.Conclusions Our nationally representative data suggest that about 20%to 40%of college students in India are at risk for IA.There is a need for further research in the reconsideration of Y-IAT cut-off points among Indian college students. | Jaison Joseph Abin Varghese Vijay VR Manju Dhandapani Sandeep Grover Suresh Sharma Deepika Khakha Sucheta Mann Biji P Varkey | 2021 | General Psychiatry2021，34，4： | 1 |
