Mesoscale eddies play vital roles in ocean processes.Although previous studies focused on eddy surface features and individual three-dimensional(3D)eddy cases in the northwestern Pacific Ocean,the analysis of unique eddy3D regional characteristics is still lacking.A 3D eddy detection scheme is applied to 9 years(2000-2008)of eddyresolving Regional Ocean Modeling System(ROMS)output to obtain a 3D eddy dataset from the surface to a depth of 1000 m in the northwestern Pacific Ocean(15°-35°N,120°-145°E).The 3D characteristics of mesoscale eddies are analyzed in two regions,namely,Box1(Subtropical Countercurrent,15°-25°N,120°-145°E)and Box2(Southern Kuroshio Extension,25°-35°N,120°-145°E).In Box1,the current is characterized by strong vertical shear and weak horizontal shear.In Box2,the current is characterized by the strong Kuroshio,topographic effect,and the westward propagation of Rossby waves.The results indicate the importance of baroclinic instability in Box1,whereas in Box2,both the barotropic and baroclinic instability are important.Moreover,the mesoscale eddies’properties in Box1 and Box2 are distinct.The eddies in Box1 have larger number and radius but a shorter lifetime.By contrast,Box2 has fewer eddies,which have smaller radius but longer lifetime.Vertically,more eddies are detected at the subsurface than at the surface in both regions;the depth of 650 m is the turning point in Box1.Above this depth,the number of cyclonic eddies(CEs)is larger than that of anticyclonic eddies(AEs).In Box2,the number of CEs is dominant vertically.Eddy kinetic energy(EKE)and mean normalized relative vorticity in Box2are significantly higher than those in Box1.With increasing depth,the attenuation trend of EKE and relative vorticity of Box1 become greater than those of Box2.Furthermore,the upper ocean(about 300 m in depth)contains 68.6%of the eddies(instantaneous eddy).Only 16.6%of the eddies extend to 1000 m.In addition,about87%of the eddies are bowl-shaped eddies in the two regions.Only about 3%are cone-shaped eddies.With in

Aqueous zinc-ion batteries are attracting considerable attention because of their high safety compared with conventional lithium-ion batteries.Manganese-based materials have been widely developed for zinc-ion batteries cathode owning to their low cost,high security and simple preparation.However,the severe volume expansion and poor stability during charging and discharging limit the further development of manganese-based cathodes.Herein,superiorα-MnO_(2)@g-C_(3)N_(4)was successfully prepared for stable zinc-ion batteries(ZIBs)cathode by introducing g-C_(3)N_(4)nanosheets.Compared with pureα-MnO_(2),αMnO_(2)@g-C_(3)N_(4)has a specific capacity of 298 mAh·g^(-1)at 0.1 A·g^(-1).Even at 1 A·g^(-1),theα-MnO_(2)@g-C_(3)N_(4)still retains 100 mAh·g^(-1)(83.4%retention after 5000 cycles),implying its excellent cycling stability.Theα-MnO_(2)@gC_(3)N_(4)-based cathode has the highest energy density(563 Wh·kg^(-1))and power energy density(2170 W·kg^(-1)).This work provides new avenues for the development of a wider range of cathode materials for ZIBs.

Understanding cost data collection tools to improve economic evaluations of health interventions

引用

Stroke & Vascular Neurology 2019年第4期4卷 214-222页

作者： John M Chapel guijing Wang Division for Heart Disease and Stroke Prevention CDCAtlantaGeorgiaUSA

Micro-costing data collection tools often used in literature include standardized comprehensive templates,targeted questionnaires,activity logs,on-site administrative databases,and direct observation.These tools are not mutually exclusive and are often used in combination.Each tool has unique merits and limitations,and some may be more applicable than others under different circumstances.Proper application of micro-costing tools can produce quality cost estimates and enhance the usefulness of economic evaluations to inform resource allocation decisions.A common method to derive both fixed and variable costs of an intervention involves collecting data from the bottom up for each resource consumed(micro-costing).We scanned economic evaluation literature published in 2008-2018 and identified micro-costing data collection tools used.We categorized the identified tools and discuss their practical applications in an example study of health interventions,including their potential strengths and weaknesses.Sound economic evaluations of health interventions provide valuable information for justifying resource allocation decisions,planning for implementation,and enhancing the sustainability of the interventions.However,the quality of intervention cost estimates is seldom addressed in the literature.Reliable cost data forms the foundation of economic evaluations,and without reliable estimates,evaluation results,such as cost-effectiveness measures,could be misleading.In this project,we identified data collection tools often used to obtain reliable data for estimating costs of interventions that prevent and manage chronic conditions and considered practical applications to promote their use.

Stroke & Vascular Neurology 2016年第1期1卷 8-15页

作者： Heesoo Joo guijing Wang Mary G George IHRC Inc AtlantaGeorgiaUSA Division for Heart Disease and Stroke Prevention US Centers for Disease Control and Prevention(US CDC)AtlantaGeorgiaUSA

Introduction:Intravenous tissue plasminogen activator(IV tPA)is a globally recommended treatment for patients with acute ischaemic stroke.We examined IV tPA use among patients aged 18–64 years with a primary diagnosis of acute ischaemic stroke in the USA and inpatient costs per hospitalisation by IV tPA use status among these patients.Methods:Using the 2010–2013 MarketScan Commercial Claims and Encounters Inpatient Data,we identified 39149 hospitalisations with a primary diagnosis of acute ischaemic stroke.We verified those with and without IV tPA by ICD-9 procedure code 99.10.We estimated trends in IV tPA use by applying logistic regression.The average inpatient costs per acute ischaemic stroke hospitalisation were assessed for subpopulations.We examined costs per acute ischaemic stroke hospitalisation using multivariate regression models controlling for IV tPA status,age,gender,urbanisation,geographic region,Charlson comorbidity index,length of hospital stays(LOS)and discharge status.Results:2546 hospitalisations(6.5%)used IV tPA.IV tPA use increased over time(2010 vs 2013;OR 1.50).Average inpatient costs per acute ischaemic stroke hospitalisation were$20331($31369 for the IV tPA group,$19563 for the non-tPA group).From multivariate analyses,higher costs per acute ischaemic stroke hospitalisation were associated with longer LOS,non-home discharge destination,and IV tPA use,which might be correlated with severity of stroke.Conclusions:Findings suggest that IV tPA use has increased in recent years while the inpatient costs per acute ischaemic stroke hospitalisation using IV tPA are substantial.Those findings are useful in better understanding the overall economic burden of stroke,short-term cost implications of using IV tPA,and for estimating the accurate cost-effectiveness of stroke treatments.

A literature review of cost-effectiveness of intravenous recombinant tissue plasminogen activator for treating acute ischaemic stroke

引用

Stroke & Vascular Neurology 2017年第2期2卷 73-83页

作者： Heesoo Joo guijing Wang Mary G George Division for Heart Disease and Stroke Prevention CDCIHRC Inc.AtlantaGeorgiaUSA Division for Heart Disease and Stroke Prevention CDCAtlantaGeorgiaUSA

Background Intravenous recombinant tissue plasminogen activator(IV rtPA)is recommended treatment for patients with acute ischaemic stroke,but the cost-effectiveness of IV rtPA within different time windows after the onset of acute ischaemic stroke is not well reviewed.Aims To conduct a literature review of the cost-effectiveness studies about IV rtPA by treatment times.Summary of review A literature search was conducted using MEDLINE,EMBASE,CINAHL and Cochrane Library,with the keywords acute ischemic stroke,tissue plasminogen activator,cost,economic benefit,saving and incremental cost-effectiveness analysis.The review is limited to original research articles published during 1995-2016 in English-language peer-reviewed journals.We found 16 studies meeting our criteria for this review.Nine of them were cost-effectiveness studies of IV rtPA treatment within 0-3 hours after stroke onset,2 studies within 3-4.5 hours,3 studies within 0-4.5 hours and 2 studies within 0-6 hours.IV rtPA is a cost-saving or a cost-effectiveness strategy from most of the study results.Only one study showed incremental cost-effectiveness ratio of IV rtPA within 1 year was marginally above US$50000 per quality-adjusted life year threshold.IV rtPA within 0-3 hours after stroke led to cost savings for lifetime or 30 years and IV rtPA within 3-4.5 hours after stroke increased costs but still was cost-effective.Conclusions The literature generally showed that IV rtPA was a dominant or a cost-effective strategy compared with traditional treatment for patients with acute ischaemic stroke without IV rtPA.The findings from the literature lacked generalisability because of limited data and various assumptions.

Carbon Energy 2019年第2期1卷 253-275页

作者： Yanying Shi guijing Liu Rencheng Jin Hui Xu Qingyao Wang Shanmin Gao School of Chemistry and Materials Science Ludong UniversityYantaiChina

With the increasing energy demand together with the deteriorating environment and decreasing fossil fuel resources,the development of highly efficient energy conversion and storage devices is one of the key challenges of both fundamental and applied research in energy technology.Melamine sponges(MS)with low density,high nitrogen content,and high porosity have been used to design and obtain three‐dimensional porous carbon electrode materials.More importantly,they are inexpensive,environment‐friendly,and easy to synthesize.There have been many reports on the modification of carbonized MS and MS‐based composites for supercapacitor and lithium battery electrode materials.In this paper,recent studies on the fabrication of electrode materials using MS as raw materials have been mainly reviewed,including carbonation,doping activation,and composite modification of MS,and expectations for the development of porous carbon materials for energy storage as a reference with excellent performance,environment‐friendliness,and long life.
