Hybrid Hierarchical Particle Swarm Optimization with Evolutionary Artificial Bee Colony Algorithm for Task Scheduling in Cloud Computing

Task scheduling plays a key role in effectively managing and allocating computing resources to meet various computing tasks in a cloud computing environment.Short execution time and low load imbalance may be the challenges for some algorithms in resource scheduling scenarios.In this work,the Hierarchical Particle Swarm Optimization-Evolutionary Artificial Bee Colony Algorithm(HPSO-EABC)has been proposed,which hybrids our presented Evolutionary Artificial Bee Colony(EABC),and Hierarchical Particle Swarm Optimization(HPSO)algorithm.The HPSO-EABC algorithm incorporates both the advantages of the HPSO and the EABC algorithm.Comprehensive testing including evaluations of algorithm convergence speed,resource execution time,load balancing,and operational costs has been done.The results indicate that the EABC algorithm exhibits greater parallelism compared to the Artificial Bee Colony algorithm.Compared with the Particle Swarm Optimization algorithm,the HPSO algorithmnot only improves the global search capability but also effectively mitigates getting stuck in local optima.As a result,the hybrid HPSO-EABC algorithm demonstrates significant improvements in terms of stability and convergence speed.Moreover,it exhibits enhanced resource scheduling performance in both homogeneous and heterogeneous environments,effectively reducing execution time and cost,which also is verified by the ablation experimental.

Graph CA: Learning From Graph Counterfactual Augmentation for Knowledge Tracing

With the popularity of online learning in educational settings, knowledge tracing(KT) plays an increasingly significant role. The task of KT is to help students learn more effectively by predicting their next mastery of knowledge based on their historical exercise sequences. Nowadays, many related works have emerged in this field, such as Bayesian knowledge tracing and deep knowledge tracing methods. Despite the progress that has been made in KT, existing techniques still have the following limitations: 1) Previous studies address KT by only exploring the observational sparsity data distribution, and the counterfactual data distribution has been largely ignored. 2) Current works designed for KT only consider either the entity relationships between questions and concepts, or the relations between two concepts, and none of them investigates the relations among students, questions, and concepts, simultaneously, leading to inaccurate student modeling. To address the above limitations,we propose a graph counterfactual augmentation method for knowledge tracing. Concretely, to consider the multiple relationships among different entities, we first uniform students, questions, and concepts in graphs, and then leverage a heterogeneous graph convolutional network to conduct representation learning.To model the counterfactual world, we conduct counterfactual transformations on students’ learning graphs by changing the corresponding treatments and then exploit the counterfactual outcomes in a contrastive learning framework. We conduct extensive experiments on three real-world datasets, and the experimental results demonstrate the superiority of our proposed Graph CA method compared with several state-of-the-art baselines.

Efficient Simultaneous Detection of Metabolites Based on Electroenzymatic Assembly Strategy

Objective and Impact Statement:We describe an electroenzymatic mediator(EM)sensor based on an electroenzymatic assembly peak separation strategy,which can efficiently realize the simultaneous detection of 3 typical cardiovascular disease(CVD)metabolites in 5μl of plasma under one test.This work has substantial implications toward improving the efficiency of chronic CVD assessment.Introduction:Monitoring CVD of metabolites is strongly associated with disease risk.Independent and time-consuming detection in hospitals is unfavorable for chronic CVD management.Methods:The EM was flexibly designed by the cross-linking of electron mediators and enzymes,and 3 EM layers with different characteristics were assembled on one electrode.Electrons were transferred under tunable potential;3 metabolites were quantitatively detected by 3 peak currents that correlated with metabolite concentrations.Results:In this study,the EM sensor showed high sensitivity for the simultaneous detection of 3 metabolites with a lower limit of 0.01 mM.The linear correlation between the sensor and clinical was greater than 0.980 for 242 patients,and the consistency of risk assessment was 94.6%.Conclusion:Metabolites could be expanded by the EM,and the sensor could be a promising candidate as a home healthcare tool for CVD risk assessment.

Identification and fine mapping of two blast resistance genes in rice cultivar 93-11

Rice blast, caused by Magnaporthe oryzae, is a major disease of rice almost worldwide. The Chinese indica cultivar 93-11 is resistant to numerous isolates of the blast fungus in China, and can be used as broad-spectrum resistance resource, particularly in japonica rice breeding programs. In this study, we identified and mapped two blast resistance genes, Pi60(t) and Pi61(t), in cv. 93-11 using F2 and F3 populations derived from a cross between the susceptible cv. Lijiangxintuanheigu(LTH) and resistant cv. 93-11 and inoculated with M. oryzae isolates from different geographic origins. Pi60(t) was delimited to a 274 kb region on the short arm of chromosome 11, flanked by InDel markers K1-4 and E12 and cosegregated with InDel markers B1 and Y10. Pi61(t) was mapped to a 200 kb region on the short arm(near the centromere) of chromosome 12, flanked by InDel markers M2 and S29 and cosegregating with InDel marker M9. In the 274 kb region of Pi60(t), 93-11 contains six NBS-LRR genes including the two Pia/ PiCO39 alleles(BGIOSGA034263 and BGIOSGA035032) which are quite close to the two Pia/ PiCO39 alleles(SasRGA4 and SasRGA5) in Sasanishiki and CO39, with only nine amino acids differing in the protein sequences of BGIOSGA035032 and SasRGA5. In the 200 kb region of Pi61(t), 93-11 contains four NBS-LRR genes, all of which show high identities in protein sequence with their corresponding NBS-LRR alleles in susceptible cv. Nipponbare. Comparison of the response spectra and physical positions between the target genes and other R genes in the same chromosome regions indicated that Pi60(t) could be Pia/PiCO39 or its allele, whereas Pi61(t) appears to be different from Pita, Pita-2, Pi19(t), Pi39(t) and Pi42(t) in the same R gene cluster. DNA markers tightly linked to Pi60(t) and Pi61(t) will enable marker-assisted breeding and map-based cloning.

A comparison of zooplankton assemblages in Nansi Lake and Hongze Lake,potential influences of the East Route of the South-to-North Water Transfer Project,China

Nansi Lake and Hongze Lake are both water storage lakes along the East Route of the South-to-North Water Transfer project(ESNT).Frequent changes in hydrologic properties are responsible factors for controlling the zooplankton community assemblages in both lakes,so we studied the possible influence of water transfer and environmental factors on zooplankton community structure and abundance.Zooplankton assemblages were investigated seasonally for one year in both lakes;a total of 133 and 122 zooplankton taxa were identified in Nansi Lake and Hongze Lake,respectively.The most dominant rotifer species were littoral,e.g.,Keratella tecta,Keratella valga and Lecane lunaris in Nansi Lake and Brachionus angularis,Brachionus forficula and Polyarthra vulgaris in Hongze Lake.Comparatively,Nansi Lake had a higher Shannon-Wiener diversity index value(5.13),while Hongze Lake had a higher species richness index(4.21).The average number of zooplankton across seasons in Nansi Lake(protozoa:774±63 ind./L,rotifers:4817±212 ind./L,cladocerans:896±14 ind./L,copepod:435±42 ind./L)was comparatively lower than Hongze Lake(protozoa:1238±63 ind./L,rotifers:6576±112 ind./L,cladocerans:1013±20 ind./L,copepod:534±25 ind./L).Canonical correspondence analysis identified differing environmental gradients that were most responsible for influencing zooplankton communities in the two lakes(Hongze Lake:NH4-N,total nitrogen,transparency and pH;Nansi:pH,temperature and total phosphorus).Frequent changes related to water transfer in lakes favoured the diversity of rotifers and protozoa communities.Zooplankton habitat preference,changes in community structure and opportunistic peaks and extinction of certain taxa were also observed in the study lakes.

Diagnosis and Treatment of a Case of Femoral Neck Fracture in Cat

Simple femoral neck fractures in dogs and cats are rare in clinic. The cause of the fracture is that the pelvis or femur is directly or indirectly subjected to external force,and it often occurs secondarily to osteoporosis caused by dysplasia of the hip joint. This paper described the diagnosis and treatment of a blue cat with femora neck fracture.

In-vivo Mutagenicity of Protein-modified Enterococcus faecalis

The mutagenicity of the protein-modified Enterococcus faecalis was evaluated by a mouse bone marrow micronucleus test and a mouse sperm abnormality test.The test substance was designed with three dose groups (1,2 and 5 g/kg·bw) and intragastrically administrated,with cyclophosphamide as a positive control and normal saline as a normal control.The micronucleus rate and sperm abnormality rate were measured.The results showed that the micronucleus rates and sperm abnormality rates in the different dose groups were not significantly different from those in normal control group ( P >0.05),while the positive control group was significantly higher than the normal control group ( P <0.01).The conclusion is that the protein-modified E.faecalis was tested to be negative in both the mouse bone marrow micronucleus test and mouse sperm abnormality test,suggesting that it has no mutagenicity in vivo.

Ames Test of Protein-modified Enterococcus faecalis

The potential mutagenicity of protein-modified Enterococcus faecalis was evaluated by the Ames test. The test subject was designed with 0. 05,0. 5,5. 0,and 50. 0 mg/dish doses,and a control group was set. With Salmonella typhimurium mutant strains TA97,TA98,TA100 and TA102 as test strains,the Ames test was carried out with( +) or without(-) S9,and the number of revertant colonies was counted. The results showed that for the protein-modified E. faecalis in the case of + S9 and-S9,the average numbers of revertant colonies of the four test strains were less than two times of that of the negative control group,and no dose-response relationship was observed. The protein-modified E. faecalis was tested to be negative in the Ames test,indicating that the test substance was not mutagenic in vitro.

Diagnosis and Treatment of a Case of Canine Infectious Venereal Tumor

Canine infectious venereal disease tumor( CTVT) is mainly due to a canine infectious intercourse tumor disease which is infected during mating.It is a malignant tumor originating from reticuloendodermis.After infection,the mucosal surface or prepuce of the urogenital tract is destroyed and bleed for a long time after being invaded by tumor tissue,which leads to inflammation of the urogenital tract and long-term blood loss,seriously affecting the health of dogs.In this paper,the clinical diagnosis and treatment of a canine infectious venereal disease( STD) tumor are described,with emphasis on the course of chemotherapy for the disease.

Effects of Benzo[a]pyrene on SOD and CAT in Kidneys from Carps

With carps as the object of study, the effects of benzo[a]pyrene concentration on SOD and CAT in carp kidneys were studied. There were three treatment groups and one control group. The exposure method was the static method. The superoxide dismutase （SOD） and catalase （CAT） activity was determined 30 d later. The results showed that after exposing to different concentrations of benzo[a]pyrene （0, 0.1, 0.5 and 1.0 μg /L） for 30 d, the SOD activity was higher in the low concentration group （0.1 μg/L） than in the control group; the 0.5 μg/L benzo[a]pyrene group had no significant difference from the control group; and under the concentration of 1.0 μg/L, the SOD activity decreased remarkably. The CAT activity was higher in the 0.1 μg/L group than in the control group, and decreased significantly in the 1.0 μg/L benzo[a]pyrene group compared with the control group. The results showed that benzo[a]pyrene had certain effects on the antioxidant enzymes in carp kidneys. This study provides a theoretical basis for water environmental pollution.

Data quality assessment for studies investigating microplastics and nanoplastics in food products: Are current data reliable?

Data on the occurrence of microplastics and nanoplastics(MP/NPs)in foods have been used to assess the human health risk caused by the consumption of MP/NPs.The reliability of the data,however,remains unclear because of the lack of international standards for the analysis of MP/NPs in foods.Therefore,the data quality needs to be assessed for accurate health risk assessment.This study developed 10 criteria applicable to the quality assessment of data on MP/NPs in foods.Accordingly,the reliability of 71 data records(69 of them only focused on MPs)was assessed by assigning a score of 2(reliable without restrictions),1(reliable but with restrictions),or 0(unreliable)on each criterion.The results showed that only three data records scored 2 or 1 on all criteria,and six data records scored 0 on as many as six criteria.A total of 58 data records did not include information on positive controls,and 12 data records did not conduct the polymer identification,which could result in the overestimation or underestimation of MP/NPs.Our results also indicated that the data quality of unprocessed foods was more reliable than that of processed foods.Furthermore,we proposed a quality assurance and quality control protocol to investigate MP/NPs in foods.Notably,the characteristics of MP/NPs used in toxicological studies and those existing in foods showed a remarkable discrepancy,causing the uncertainty of health risk assessment.Therefore,both the estimated exposure of MP/NPs and the claimed potential health risks should be treated with caution.
