Abstract. Although the anthropogenic emissions of SO2 have decreased significantly in China, decrease SO42- PM2.5 is much smaller than that SO2. This implies an enhanced formation rate ambient air, and mechanism still under debate. work investigated particulate sulfate based on statistical analysis long-term observations Shijiazhuang Beijing supported with flow tube experiments. Our main findin...

The paper is concerned with variants of the successive overrelaxation method (SOR method) for solving the linear system Au = b. Necessary and sufficient conditions are given for the convergence of the symmetric and unsymmetric SOR methods when A is symmetric. The modified SOR, symmetric SOR, and unsymmetric SOR methods are also considered for systems of the form DiHt — Cau2 = b¡, — CLui + D2u2 ...

The clinical evaluation of failure to thrive (FTT) includes a thorough history and physical examination; observation of parent–child interactions; observation and documentation of the child’s feeding patterns; and a home visit by an appropriately trained health care professional (Strength of Recommendation [SOR]: C). Further diagnostic testing should be performed as indicated by positive fi ndi...

Evidence-Based Answer Daily sunscreen use reduces the incidence of squamous cell carcinoma but not the incidence of basal cell carcinoma. (Strength of Recommendation [SOR]: B, based on a single randomized controlled trial with less than 13 years of follow-up). It is unclear whether there are longer-term effects. There is no consistent, conclusive evidence that sunscreen use prevents melanoma. (...

Yes. brushing twice daily with topical fluoride toothpaste decreases the incidence of dental caries in infants and toddlers (strength of recommendation [Sor]: a, based on meta-analyses of randomized controlled trials [rCts]). High-concentration fluoride toothpaste delivers superior caries protection, but causes more dental fluorosis. use of high-concentration fluoride toothpaste should be targe...

In this paper, we propose the SOR network with fuzzy inference based evaluation inspired by brain function. In the proposed method, controller design and knowledge acquisition are achieved simultaneously. All the designer has to do is to describe evaluation rules for the input/output data set sampled by trial and error. In the description process, only designer’s commonsense knowledge is requir...

No evidence clearly supports the practice of increased fetal surveillance in the pregnancies of women with well-controlled (ie, fasting blood sugar <105 mg/dL) class A1 gestational diabetes (strength of recommendation [SOR]: B, consistent retrospective cohort studies). However, a number of guidelines recommend beginning surveillance of some kind between 32 and 40 weeks based on cumulative risk ...

Rationale This study explored subtypes of sensory processing disorder (SPD) by examining the clinical presentations of cluster groups that emerged from scores of children with SPD on the Sensory Processing 3-Dimension (SP-3D) Inventory. Method A nonexperimental design was used involving data extraction from the records of 252 children with SPD. Exploratory cluster analyses were conducted with...

A curious phenomenon when it comes to solving the linear system formulation of the PageRank problem is that while the convergence rate of Gauss–Seidel shows an improvement over Jacobi by a factor of approximately two, successive overrelaxation (SOR) does not seem to offer a meaningful improvement over Gauss–Seidel. This has been observed experimentally and noted in the literature, but to the be...
