Parkinson’s disease is a neurodegenerative disorder that inflicts irreversible damage on humans.Some experimental data regarding Parkinson’s patients are redundant and irrelevant,posing significant challenges for disease detection.Therefore,there is a need to devise an effective method for the selective extraction of disease-specific information,ensuring both accuracy and the utilization of fewer features.In this paper,a Binary Hybrid Artificial Hummingbird and Flower Pollination Algorithm(FPA),called BFAHA,is proposed to solve the problem of Parkinson’s disease diagnosis based on speech signals.First,combining FPA with Artificial Hummingbird Algorithm(AHA)can take advantage of the strong global exploration ability possessed by FPA to improve the disadvantages of AHA,such as premature convergence and easy falling into local optimum.Second,the Hemming distance is used to determine the difference between the other individuals in the population and the optimal individual after each iteration,if the difference is too significant,the cross-mutation strategy in the genetic algorithm(GA)is used to induce the population individuals to keep approaching the optimal individual in the random search process to speed up finding the optimal solution.Finally,an S-shaped function converts the improved algorithm into a binary version to suit the characteristics of the feature selection(FS)tasks.In this paper,10 high-dimensional datasets from UCI and the ASU are used to test the performance of BFAHA and apply it to Parkinson’s disease diagnosis.Compared with other state-of-the-art algorithms,BFAHA shows excellent competitiveness in both the test datasets and the classification problem,indicating that the algorithm proposed in this study has apparent advantages in the field of feature selection.

Tissue engineering(TE)is critical in oral and craniofacial reconstruction.One of the most popular topics on the biomaterial-based tissue regeneration process may be the interaction between cells and scaffolds.An increasing number of studies have identified the variables affecting cell-scaffold interaction.The creation and investigation of new scaffolds for TE and regenerative medicine based on specific interactions have become possible owing to these findings.This review discusses the effects of various types of scaffold materials on cells in TE.Because the intrinsic properties of scaffolds are essential,the influence of the physical,chemical,mechanical,and biological characteristics of scaffold materials on cell-scaffold interaction that has been discovered in recent research is elaborated in this review.The components carried by scaffolds,the degradation process,and the role of degraded products in cell-scaffold interactions are examined.Further,the roles of cells,including cell types,functions,and adhesion mechanisms,and extracellular matrix are discussed.Finally,the latest research progress on cell-scaffold interactions among various engineered tissues or organs in the oral and craniofacial region is summarized.A deeper understanding of cell-scaffold interactions is anticipated to benefit the development of TE and regenerative medicine.

The ammonium exceedance discharge from sewage treatment plants has a great risk to the stable operation of subsequent constructed wetlands(CWs).The effects of high ammonium shocks on submerged macrophytes and epiphytic biofilms on the leaves of submerged macrophytes in CWs were rarely mentioned in previous studies.In this paper,the 16S rRNA sequencing method was used to investigate the variation of the microbial communities in biofilms on the leaves of Vallisneria natans plants while the growth characteristics of V.natans plants were measured at different initial ammonium concentrations.The results demonstrated that the total chlorophyll and soluble sugar synthesis of V.natans plants decreased by 51.45%and 57.16%,respectively,and malondialdehyde content increased threefold after8 days if the initial NH_(4)^(+)-N concentration was more than 5 mg/L.Algal density,bacterial quantity,dissolved oxygen,and pH increased with high ammonium shocks.The average removal efficiencies of total nitrogen and NH_(4)^(+)-N reached 73.26%and 83.94%,respectively.The heat map and relative abundance analysis represented that the relative abundances of phyla Proteobacteria,Cyanobacteria,and Bacteroidetes increased.The numbers of autotrophic nitrifiers and heterotrophic nitrification aerobic denitrification(HNAD)bacteria expanded in biofilms.In particular,HNAD bacteria of Flavobacterium,Hydrogenophaga,Acidovorax,Acinetobacter,Pseudomonas,Aeromonas,and Azospira had higher abundances than autotrophic nitrifiers because there were organic matters secreted from declining leaves of V.natans plants.The analysis of the nitrogen metabolic pathway showed aerobic denitrification was the main nitrogen removal pathway.Thus,the nitrification and denitrification bacterial communities increased in epiphytic biofilms on submerged macrophytes in constructed wetlands while submerged macrophytes declined under ammonium shock loading.

Regenerative endodontic procedures(REPs)is a biologic-based treatment modality for immature permanent teeth diagnosed with pulp necrosis.The ultimate objective of REPs is to regenerate the pulp-dentin complex,extend the tooth longevity and restore the normal function.Scientific evidence has demonstrated the efficacy of REPs in promotion of root development through case reports,case series,cohort studies,and randomized controlled studies.However,variations in clinical protocols for REPs exist due to the empirical nature of the original protocols and rapid advancements in the research field of regenerative endodontics.The heterogeneity in protocols may cause confusion among dental practitioners,thus guidelines and considerations of REPs should be explicated.This expert consensus mainly discusses the biological foundation,the available clinical protocols and current status of REPs in treating immature teeth with pulp necrosis,as well as the main complications of this treatment,aiming at refining the clinical management of REPs in accordance with the progress of basic researches and clinical studies,suggesting REPs may become a more consistently evidence-based option in dental treatment.

橡胶种植公司是近代上海股市中公司数量最多的一个行业板块,然而,相关研究一般仅限于清末“橡胶风潮”这一短暂时期,而忽略了这些公司的长期业绩表现。我们收集了1937年之前上海众业公所上市的所有橡胶公司的股价、股利和重组等信息,并在此基础上编制了1909一1936年的橡胶股年度业绩指数以及橡胶风潮时期的月度业绩指数。我们发现,橡胶风潮的影响主要限于二级市场的橡胶股价格和从事橡胶股投机的钱庄,并未给其他行业股价带来严重的负面影响。风潮之后,大部分橡胶公司的生产经营仍在正常开展。橡胶股尽管波动巨大,然而其长期收益率高于无风险利率,即使经过风险调整,橡胶股仍然存在一定的超额收益。本文从橡胶板块的视角为近代上海股市的收益和风险状况提供了新的定量化认识。
