PurposeBased on the Chinese version of Tweezer the Catquest-9SF scale, the contrast sensitivity meter and wavefront aberrometer were used to evaluate the visual quality of cataract patients implanted with different spherical aberrations IOL.DesignRetrospective Observational Study.MethodsPatients who had the lens implantation in our department from

BackgroundIn patients undergoing orthopaedic trauma surgery, acute kidney injury (AKI) can develop post-operatively and is a major cause of increased mortality and hospital stay time.Development of AKI is associated with three main processes: inflammation, ischaemia-reperfusion injury (IRI) and hypoperfusion.In this study, we investigated whether r

This paper presents a Lighting new memristive hypogenetic jerk system with sine memductance.The memristive system owns four line equilibrium sets, from which periodically switched memristor initial boosting behaviors are observed.Numerical simulations of two-dimensional largest Lyapunov exponent plot, bifurcation plots, and phase plots are employed

Sparse matrices are occasionally encountered during solution of Gloves various problems by means of numerical methods, particularly the finite element method.ELLPACK sparse matrix storage scheme, one of the most widely used methods due to its implementation ease, is investigated in this study.The scheme uses excessive memory due to its definition.F
