In cloud manufacturing environment, for a scheduling Job, there may be a lot of servicizing manufacturing resources and manufacturing capability that can be used to support for its realizing. Therefore, how to efficiently solve FJSS problem becomes more complex and significant. First, this paper uses disjunctive graph model to analyze the characteristic of FJSS problems, and then, focusing on machine selection sub problem, this paper designs multi-rules to solve machine selection conflicts in different scenarios. Finally, on this basis, an improved multi-rules-based ACO algorithm is proposed. The algorithm is applied to the typical examples of the flexible job-shop scheduling problem. Compared with other algorithms, final experimental results indicate that this algorithm is effective.

Objective: cAMP and mature promoting factor (MPF) play critical roles during the maturation of mammalian oocytes. The aim of this study was to produce the offspring from denuded oocytes (DOs) in mice by regulating cAMP and MPF. Methods: In this study, we used DOs at the germinal vesicle (GV) stage in mice and regulated levels of cAMP and MPF in DOs by adding Forskolin and PD166285 during in vitro maturation without follicle stimulating hormone and luteinizing hormone, respectively. Results: Combined use of 50 μM Forskolin for 3 h and 2.5 μM PD166285 for additional 21 h enhanced the developmental competence of DOs, maturation rate of DOs was 76.71%± 4.11%, blastocyst rate was 18.33%±4.44% after parthenogenetic activation (PA). The DOs could successfully be fertilized with sperm in vitro, cleavage rate was 17.02%±5.82% and blastocyst rate was 5.65%±3.10%. Besides, 2-cell in vitro fertilization embryos from DOs produced 4 normal live offspring (4/34). Conclusion: The results confirmed that the combination of Forskolin and PD166285 can induce DOs to complete meiosis process and produce normal offspring.

Decolorization and organic degradation of wastewater containing multiple dyes are still challenging inwastewater treatment. Magnetic biochar coupled with advanced oxidation is a potential solution to this issue. In this study,a series of magnetite-based biochar composites (Fe3O4@C) was prepared and compared for the removal of mixed dyes,including methyl orange (MO), rhodamine B (RhB), methylene blue (MB), and an organic macromolecule, humic acid(HA). The pyrolysis of watermelon rinds followed by precipitation of Fe3O4 onto the biochar was selected as the optimummethod to prepare an adsorbent and catalyst to couple binary oxidants (hypochlorite and persulfate) for color and totalorganic carbon removal. Persulfate was prone to degrade HA and MB, while hypochlorite was inclined to oxidize MO andRhB. Fe3O4@C exhibited better dye removal performance in coupling with binary oxidants than with a single oxidant. Formixed dye solutions with an initial concentration of 50 mg/l for each dye, the highest TOC (57.24±3.17 %) and the colorremoval efficiencies (94.13±1.68 %) for the mixed dye solution were achieved at a sorbent dosage of 1 g/l and an oxidantdosage of 5 mmol/l for both hypochlorite and persulfate. Multiple free radicals, including hydroxyl radicals, sulfateradicals, and hypochlorite-induced radicals, play critical roles in the degradation of mixed dyes and color removal. Theregeneratibility and reutilization of the magnetic Fe3O4@C composite were effective and stable. The results obtained inthis study show that the combined Fe3O4@C and binary oxidants technique is promising for the treatment of multi-dyewastewater.

Hybrid Recommendation Algorithm for User Satisfaction-oriented Privacy Model

Yinggang Sun,Hongguo Zhang,Luogang Zhang,Chao Ma,Hai Huang,Dongyang Zhan,Jiaxing Qu 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.10

Anonymization technology is an important technology for privacy protection in the process of data release. Usually, before publishing data, the data publisher needs to use anonymization technology to anonymize the original data, and then publish the anonymized data. However, for data publishers who do not have or have less anonymized technical knowledge background, how to configure appropriate parameters for data with different characteristics has become a more difficult problem. In response to this problem, this paper adds a historical configuration scheme resource pool on the basis of the traditional anonymization process, and configuration parameters can be automatically recommended through the historical configuration scheme resource pool. On this basis, a privacy model hybrid recommendation algorithm for user satisfaction is formed. The algorithm includes a forward recommendation process and a reverse recommendation process, which can respectively perform data anonymization processing for users with different anonymization technical knowledge backgrounds. The privacy model hybrid recommendation algorithm for user satisfaction described in this paper is suitable for a wider population, providing a simpler, more efficient and automated solution for data anonymization, reducing data processing time and improving the quality of anonymized data, which enhances data protection capabilities.

Objective: The aim of this study was to reveal the role and regulatory mechanism of miR-188-5p in the proliferation and differentiation of goat muscle satellite cells. Methods: Goat skeletal muscle satellite cells isolated in the pre-laboratory were used as the test material. First, the expression of miR-188-5p in goat muscle tissues at different developmental stages was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). In addition, miR-188-5p was transfected into goat skeletal muscle satellite cells by constructing mimics and inhibitors of miR-188-5p, respectively. The changes of differentiation marker gene expression were detected by qPCR method. Results: It was highly expressed in adult goat latissimus dorsi and leg muscles, goat fetal skeletal muscle, and at the differentiation stage of muscle satellite cells. Overexpression and interference of miR-188-5p showed that miR-188-5p inhibited the proliferation and promoted the differentiation of goat muscle satellite cells. Target gene prediction and dual luciferase assays showed that miR-188-5p could target the 3'untranslated region of the calcium/calmodulin dependent protein kinase II beta (CAMK2B) gene and inhibit luciferase activity. Further functional studies revealed that CAMK2B promoted the proliferation and inhibited the differentiation of goat muscle satellite cells, whereas si-CAMK2B restored the function of miR-188-5p inhibitor. Conclusion: These results suggest that miR-188-5p inhibits the proliferation and promotes the differentiation of goat muscle satellite cells by targeting CAMK2B. This study will provide a theoretical reference for future studies on the molecular mechanisms of skeletal muscle development in goats.

Objective: The purpose of this study was to explore the effect of sodium salicylate (SS) on semen preservation and metabolic regulation in goats. Methods: Under the condition of low temperature, SS was added to goat semen diluent to detect goat sperm motility, plasma membrane, acrosome, antioxidant capacity, mitochondrial membrane potential (MMP) and metabonomics. Results: The results show that at the 8th day of low-temperature storage, the sperm motility of the 20 μM SS group was 66.64%, and the integrity rates of the plasma membrane and acrosome were both above 60%, significantly higher than those of the other groups. The activities of catalase and superoxide dismutase in the sperm of the 20 μM SS group were significantly higher than those of the control group, the contents of reactive oxygen species and malondialdehyde were significantly lower than those in the control group, the MMP was significantly higher than that in the control group, and the contents of Ca2+ and total cholesterol were significantly higher than those in the control group. Through metabonomics analysis, there were significant metabolic differences between the control group and the 20 μM SS group. Twenty of the most significant metabolic markers were screened, mainly involving five metabolic pathways, of which nicotinic acid and nicotinamide metabolic pathways were the most significant. Conclusion: The results indicate that SS can effectively improve the low-temperature preservation quality of goat sperm.

Development of the vapor film thickness correlation in porous corrosion deposits on the cladding in PWR

Shen Yuan,Duan Zhengang,Lu Chuan,Ji Li,Jiao Caishan,Hou Hongguo,Chao Nan,Zhang Meng,Zhou Yu,Gao Yang 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.12

The porous corrosion deposits (known as CRUD) adhered to the cladding have an important effect on the heat transfer from fuel rods to coolant in PWRs. The vapor film is the main constituent in the two-phase film boiling model. This paper presents a vapor film thickness correlation, associated with CRUD porosity, CRUD chimney density, CRUD particle size, CRUD thickness and heat flux. The dependences of the vapor film thickness on the various influential factors can be intuitively reflected from this vapor film thickness correlation. The temperature, pressure, and boric acid concentration distributions in CRUD can be well predicted using the two-phase film boiling model coupled with the vapor film thickness correlation. It suggests that the vapor thickness correlation can estimate the vapor film thickness more conveniently than the previously reported vapor thickness calculation methods.

Hong Guo,Zisong Bai,Yangyang Xu,Xueqin Wu,Ning Li,Yan Zhu,Xiaoming Wang,Peng Zhang 대한약학회 2017 Archives of Pharmacal Research Vol.40 No.7

Pongamia pinnata (Linn.) Pierre has anti-inflammatory activity and could significantly decrease serum tumor necrosis factor-a and IL-10 in arthritic rats. Previous research indicated the typical chemical constituent in P. pinnata is furanoflavone. Guided by anti-inflammatory active assay and UPLC-HRESIMS chromatography, 22 compounds were isolated from the ethanol extract of P. pinnata seedpods. One novel furanoflavone, 40-hydroxypinnatin, was elucidated by HRESIMS, 1D- and 2D-NMR spectra. The 21 known compounds, including 9 furanoflavone, were identified by comparing their NMR data with the previous data in reference. In the known compounds, 5 were isolated for the first time from the species. The anti-inflammatory activities were assayed by assessing LPS-induced NO production in BV-2 cells. 12 compounds can inhibit the production of NO without cytotoxicity at concentration of 50 lM. Among them, compounds 4 can significantly inhibit the production of NO, with the IC50 value of 31.36 lM.
