With the development of big data and social computing,large-scale group decisionmaking(LGDM)is nowmerging with social networks.Using social network analysis(SNA),this study proposes an LGDM consensus model that considers the trust relationship among decisionmakers(DMs).In the process of consensusmeasurement:the social network is constructed according to the social relationship among DMs,and the Louvain method is introduced to classify social networks to form subgroups.In this study,the weights of each decision maker and each subgroup are computed by comprehensive network weights and trust weights.In the process of consensus improvement:A feedback mechanism with four identification and two direction rules is designed to guide the consensus of the improvement process.Based on the trust relationship among DMs,the preferences are modified,and the corresponding social network is updated to accelerate the consensus.Compared with the previous research,the proposedmodel not only allows the subgroups to be reconstructed and updated during the adjustment process,but also improves the accuracy of the adjustment by the feedbackmechanism.Finally,an example analysis is conducted to verify the effectiveness and flexibility of the proposed method.Moreover,compared with previous studies,the superiority of the proposed method in solving the LGDM problem is highlighted.

In this study,a modified continuous-flow nitrifying reactor was successfully operated for rapid cultivation of micro-granules and achieving robust nitritation.Results showed that sludge granulation with mean size of ca.100μm was achieved within three weeks by gradually increasing settling velocity-based selection pressure from 0.48 to 0.9 m/hr.Though Nitrospira like nitrite-oxidizing bacteria(NOB)were enriched in the micro-granules with a ratio between ammonia-oxidizing bacteria(AOB)and NOB of 5.7%/6.5% on day 21,fast nitritation was achieved within one-week by gradually increasing of influent ammonium concentration(from 50 to 200 mg/L).Maintaining ammonium in-excess was the key for repressing NOB in the micro-granules.Interestingly,when the influent ammonium concentration switched back to 50 mg/L still with the residual ammonium of 15–25 mg/L,the nitrite accumulation efficiency increased from 90%to 98%.Experimental results suggested that the NOB repression was intensified by both oxygen and nitrite unavailability in the inner layers of micro-granules.Unexpectedly,continuous operation with ammonium in excess resulted in overproduction of extracellular polysaccharides and overgrowth of some bacteria(e.g.,Nitrosomonas,Arenimonas,and Flavobacterium),which deteriorated the micro-granule stability and drove the micro-granules aggregation into larger ones with irregular morphology.However,efficient nitritation was stably maintained with extremely high ammonium oxidation potential(>50 mg/g VSS/hr)and nearly complete washout of NOB was obtained.This suggested that smooth and spherical granule was not a prerequisite for achieving NOB wash-out and maintaining effective nitritation in the granular reactor.Overall,the microgranules exhibited a great practical potential for high-rate nitritation.

We report on deep-to-near-UV transient absorption spectra of core-shell Au∕SiO_(2) and Au∕TiO_(2) nanoparticles(NPs) excited at the surface plasmon resonance of the Au core, and of UV-excited bare anatase TiO_(2) NPs. The bleaching of the first excitonic transition of anatase TiO_(2) at ~3.8 e V is a signature of the presence of electrons/holes in the conduction band(CB)/valence band(VB) of the material. We find that while in bare anatase TiO_(2) NPs, two-photon excitation does not occur up to the highest used fluences(1.34 mJ∕cm^(2)), it takes place in the TiO_(2) shell at moderate fluences(0.18 mJ∕cm^(2)) in Au∕TiO_(2) core-shell NPs, as a result of an enhancement due to the plasmon resonance. We estimate the enhancement factor to be of the order of ~10~8–10~9. Remarkably, we observe that the bleach of the 3.8 eV band of TiO_(2) lives significantly longer than in bare TiO_(2), suggesting that the excess electrons/holes in the conduction/valence band are stored longer in this material.

Plasmon-generated hot electrons show great potential for driving chemical reactions.The utilization efficiency of hot electrons is highly dependent on the interaction of the electronic states at the interfaces between plasmonic nanoparticles and other materials/molecules.Strong interaction can produce new hybridized electron states,which permit direct hot-electron transfer,a more efficient transfer mechanism.However,Au usually has very weak interaction with most molecules because of its inertness,which makes direct hot-electron transfer impossible.Herein,the improvement of the hot-electron transfer efficiency from Au to N_(2)is demonstrated by introducing a Ru bridging layer.Both the N_(2)fixation rate and Faradic efficiency(FE)are enhanced by the excitation of plasmons.The enhancement of the N_(2)fixation rate is found to arise from plasmon-generated hot electrons.Theoretical calculations show that the strong interaction of the Ru electronic states with the N_(2)molecular orbitals produces new hybridized electronic states,and the Ru d electrons also strongly couple with the Au sp electrons.Such a bridging role of Ru makes direct hot-electron transfer from Au to N_(2)possible,improving the FE of nitrogen fixation.Our findings demonstrate a new approach to increasing the utilization efficiency of plasmonic hot electrons for chemical reactions and will be helpful to the design of plasmonic catalysts in the future.

Fibroblast activation protein(Fap)is a serine protease that degrades denatured type I collagen,α2-antiplasmin and FGF21.Fap is highly expressed in bone marrow stromal cells and functions as an osteogenic suppressor and can be inhibited by the bone growth factor Osteolectin(Oln).Fap is also expressed in synovial fibroblasts and positively correlated with the severity of rheumatoid arthritis(RA).However,whether Fap plays a critical role in osteoarthritis(OA)remains poorly understood.Here,we found that Fap is significantly elevated in osteoarthritic synovium,while the genetic deletion or pharmacological inhibition of Fap significantly ameliorated posttraumatic OA in mice.Mechanistically,we found that Fap degrades denatured type II collagen(Col II)and Mmp13-cleaved native Col II.Intra-articular injection of r Fap significantly accelerated Col II degradation and OA progression.In contrast,Oln is expressed in the superficial layer of articular cartilage and is significantly downregulated in OA.Genetic deletion of Oln significantly exacerbated OA progression,which was partially rescued by Fap deletion or inhibition.Intra-articular injection of r Oln significantly ameliorated OA progression.Taken together,these findings identify Fap as a critical pathogenic factor in OA that could be targeted by both synthetic and endogenous inhibitors to ameliorate articular cartilage degradation.

Objective: To critically evaluate and summarize the methodological quality of systematic reviews(SRs)and present objective and important outcomes on the effectiveness of traditional Chinese medicine(TCM) therapies, including Chinese herbal medicine(CHM), acupuncture, and moxibustion, for diarrheapredominant irritable bowel syndrome(IBS-D).Methods: We conducted a comprehensive literature search for SRs in 7 databases until April 16, 2022.Two reviewers independently extracted data and assessed the methodological quality of the reviews according to the Assessing the Methodological Quality of Systematic Reviews 2(AMSTAR-2), the Risk of Bias in Systematic reviews(ROBIS) tool, and the Preferred Reporting Item for Systematic Review and Meta-analysis(PRISMA) statement. The Grading of Recommendations, Assessment, Development, and Evaluation(GRADE) was used to rate the quality of evidence.Results: IBS-D patients included in 12 reviews were diagnosed in accordance with the Rome criteria, 9 reviews focused on CHM, 2 articles observed moxibustion and heat-sensitive moxibustion, 1 article studied acupuncture and CHM. The outcomes of the SRs were the effectiveness rate, the total effectiveness rate,global symptom improvement, and adverse effects. Based on AMSTAR-2, which measures the quality of methodology, all of the included studies were of low or critically low quality. According to the ROBIS tool, 10 SRs(83.33%) had a high risk of bias. With the PRISMA checklist, only 3 SRs reached over 90% compliance.Based on GRADE, most evidence was of low quality, and there was a moderate quality of evidence that the effectiveness rate of modified-Tongxie Yaofang was superior to Western medicine in the treatment of IBS-D.Conclusion: Given the suboptimal reporting and methodological quality of existing SRs, more studies are needed to clarify whether TCM therapies are more effective or safe than pharmacological medicine.Future studies should combine evidence-based medicine with TCM research according to the characteristics of TCM.

(Metal yolk)/(porous ceria shell)nanostructures for high-performance plasmonic photocatalysis under visible light

引用

Nano Research 2020年第5期13卷 1354-1362页

作者： Nina Jiang Danyang Li Lili Liang Qing Xu Lei Shao Shi-Bin wang Aizheng Chen jianfang wang College of Chemical Engineering Huaqiao UniversityXiamen 361021China Department of Physics The Chinese University of Hong KongShatinHong Kong SARChina Country Fujian Provincial Key Laboratory of Biochemical Technology(Huaqiao University) Xiamen 361021China

We describe a route to the preparation of(metal yolk)/(porous ceria shell)nanostructures through the heterogeneous growth of ceria on porous metal nanoparticles followed by the calcination-induced shrinkage of the nanoparticles.The approach allows for the control of the ceria shell thickness,the metal yolk composition and size,which is difficult to realize through common templating approaches.The yolk/shell nanostructures with monometallic Pt and bimetallic PtAg yolks featuring plasmon-induced broadband light absorption in the visible region are rationally designed and constructed.The superior photocatalytic activities of the obtained nanostructures are demonstrated by the selective oxidation of benzyl alcohol under visible light.The excellent activities are ascribed to the synergistic effects of the metal yolk and the ceria shell on the light absorption,electron-hole separation and efficient mass transfer.Our synthesis of the(metal yolk)/(porous ceria shell)nanostructures points out a way to the creation of sophisticated heteronanostructures for high-performance photocatalysis.

Mechanism on minimization of excess sludge in oxic-settling- anaerobic (OSA) process

引用

Frontiers of Environmental Science & Engineering 2008年第1期2卷 36-43页

作者： jianfang wang Qingliang ZHAO Wenbiao JIN Jikan LIN School of Municipal&Environmental Engineering Harbin Institute of TechnologyHarbin 150090China Harbin Institute of Technology Campus of Shenzhen University Town Shenzhen 518055China Bio-treat Technology Limited Dongguan 523581China

The oxic-settling-anaerobic(OSA)process is a promising wastewater treatment technique for efficiently reducing sludge production and improving the stability of process operation.In this paper,the possible factors of sludge reduction such as sludge decay,uncoupled metabol-ism,and anaerobic oxidation with low sludge production were discussed in the OSA process.It has been confirmed that sludge decay is the decisive cause in the OSA process,accounting for 66.7%of sludge production reduction.Sludge decay includes hydrolysis and acidogenesis of dead microorganisms and particle organic carbon adsorbed in sludge floc and endogenous metabolism.By batch experi-ments,it has been proven that there is energetic uncoupling in the OSA system since microorganisms were exposed to alternative anaerobic and aerobic environment.It accounts for about 7.5%of sludge production reduction.Soluble chemical oxygen demand(SCOD)released from the anaerobic sludge tank in the OSA process was used as the substrate for cryptic growth.The substrate was used for anoxic denitrifying,anaerobic phosphorus release,sulfate reduction,and methane production.These anaerobic reactions in the sludge anaerobic tank have lower sludge production than in the aerobic oxidation when equivalent SCOD is consumed,which may lead to approximately 23%of sludge reduction in the OSA process.It has been concluded that multiple causes resulted in the minimization of excess sludge in the OSA system.The microbial community structure and diversity of sludge samples from the CAS(conventional activated sludge)and OSA systems were investigated by 16 SrDNA PCR-DG-DGGE(poly-merase chain reaction-double gradient-denaturing gradient gel electrophoresis).DGGE profile and cluster analysis showed more abundant species in the OSA system contrasting to microbial communities in the CAS system.
