Yin Ren,Aihuang Guo,Chunlin Song 한국인터넷정보학회 2023 KSII Transactions on Internet and Information Syst Vol.17 No.3

The rapid development of mobile communication not only has made the industry gradually diversified, but also has enhanced the service quality requirements of users. In this regard, it is imperative to consider jointly network slicing and mobile edge computing. The former mainly ensures the requirements of varied vertical services preferably, and the latter solves the conflict between the user's own energy and harsh latency. At present, the integration of the two faces many challenges and need to carry out at different levels. The main target of the paper is to minimize the energy consumption of the system, and introduce a multi-slice joint task offloading and resource allocation scheme for massive multiple input multiple output enabled heterogeneous networks. The problem is formulated by collaborative optimizing offloading ratios, user association, transmission power and resource slicing, while being limited by the dissimilar latency and rate of multi-slice. To solve it, assign the optimal problem to two sub-problems of offloading decision and resource allocation, then solve them separately by exploiting the alternative optimization technique and Karush-Kuhn-Tucker conditions. Finally, a novel slices task offloading and resource allocation algorithm is proposed to get the offloading and resource allocation strategies. Numerous simulation results manifest that the proposed scheme has certain feasibility and effectiveness, and its performance is better than the other baseline scheme.

Ren, Yang-Wu,Yin, Zhi-Hua,Wan, Yan,Guan, Peng,Wu, Wei,Li, Xue-Lian,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Background: Cell cycle deregulation is a major component of carcinogenesis. The p53 tumor suppressor gene plays an important role in regulating cell cycle arrest, and mouse double minute 2 (MDM2) is a key regulator of p53 activity and degradation. Abnormal expression of p53 and MDM2 occurs in various cancers including lung cancer. Methods: We investigated the distribution of the p53 Arg72Pro (rs1042522) and MDM2 SNP309 (rs2279744) genotypes in patients and healthy control subjects to assess whether these single nucleotide polymorphisms (SNPs) are associated with an increased risk of lung adenocarcinomas in Chinese female non-smokers. Genotypes of 764 patients and 983 healthy controls were determined using the TaqMan SNP genotyping assay. Results: The p53 Pro/Pro genotype (adjusted OR = 1.55, 95% CI = 1.17-2.06) significantly correlated with an increased risk of lung adenocarcinoma, compared with the Arg/Arg genotype. An increased risk was also noted for MDM2 GG genotype (adjusted OR = 1.68, 95% CI = 1.27-2.21) compared with the TT genotype. Combined p53 Pro/Pro and MDM2 GG genotypes (adjusted OR = 2.66, 95% CI = 1.54-4.60) had a supermultiplicative interaction with respect to lung adenocarcinoma risk. We also found that cooking oil fumes, fuel smoke, and passive smoking may increase the risk of lung adenocarcinomas in Chinese female non-smokers who carry p53 or MDM2 mutant alleles. Conclusions: P53 Arg72Pro and MDM2 SNP309 polymorphisms, either alone or in combination, are associated with an increased lung adenocarcinoma risk in Chinese female non-smokers.

Objective: Compared to Mimas pigeons, Shiqi pigeons exhibit greater tolerance to coarse feeding because of their abundant gut microbiota. Here, to investigate the potential of utilizing intestinal flora derived from Shiqi pigeons, the intestinal flora and body indices of Mimas squabs were evaluated after fecal microbiota transplantation (FMT) from donors.Methods: A total of 90 one-day-old squabs were randomly divided into the control group (CON), the low-concentration group (LC) and the high-concentration group (HC): gavaged with 200 μL of bacterial solution at concentrations of 0, 0.1, and 0.2 g/15 mL, respectively.Results: The results suggested that FMT improved the body weight of Mimas squabs in the HC and LC groups (p<0.01), and 0.1 g/15 mL was the optimal dose during FMT. After 16S rRNA sequencing was performed, compared to those in the CON group, the abundance levels of microflora, especially Lactobacillus, Muribaculaceae, and Megasphaera (p<0.05), in the FMT-treated groups were markedly greater. Random forest analysis indicated that the main functions of key microbes involve pathways associated with metabolism, further illustrating their important role in the host body.Conclusion: FMT has been determined to be a viable method for augmenting the weight and intestinal microbiota of squabs, representing a unique avenue for enhancing the economic feasibility of squab breeding.

Yin, Q.Q.,Chang, J.,Zuo, R.Y.,Chen, L.Y.,Chen, Q.X.,Wei, X.Y.,Guan, Q.F.,Sun, J.W.,Zheng, Q.H.,Yang, X.,Ren, G.Z. Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.2

In order to improve the availability of phytase and probiotics together, a phytase gene from Aspergillus ficuum has been expressed in Lactobacillus. In this study, the transformed Lactobacillus with phytase gene was fed to pigs to determine its effect on pig production, feed conversion and gut microbes. Forty eight, 60-day-old, castrated pigs (Duroc${\times}$Landrace${\times}$Pietrain) were assigned to 6 groups, 8 pigs for each group. Group 1 was the control, group 2 was added with chlortetracycline (500 mg/kg), group 3 was added with the transformed Lactobacillus (500 mg/kg) with 20% (w/w) of calcium monohydrogen phosphate (CMP, $CaHPO_{4}$) removed, group 4 was added with the natural Lactobacillus (500 mg/kg) with 20% (w/w) of CMP removed, group 5 was added with the transformed Lactobacillus (500 mg/kg) with 40% (w/w) of CMP removed, group 6 was added with phytase (500 mg/kg) with 40% (w/w) of CMP removed. The results showed: i) the average daily gain (ADG) was improved in groups 2, 3 and 4 (p<0.05); ii) the diarrhea rates in the groups added with Lactobacillus were lower than in the other groups (p<0.05), in which the transformed Lactobacillus had more effect on reducing digestive disease; iii) the transformed Lactobacillus was most effective in improving the digestibilities of crude protein (CP), calcium (Ca), phosphorus (P), compared with the other groups (p<0.05); iv) Lactobacillus could increase lactic acid bacterium number and ammonia concentrations, and decrease pH values and E. coli number in pig feces (p<0.05); v) the phytase activity in the feces of pigs fed with the transformed Lactobacillus was 133.32 U/g, which was higher than in group 4 (9.58 U/g, p<0.05), and was almost the same as group 6 (135.94 U/g); vi) the transformed Lactobacillus could increase serum concentrations of IgA, triglyceride, and glutamic oxaloacetic transaminase activity (p<0.05), and had no significant effect on other serum indexes (p>0.05).

Yin, Zhi-Hua,Cui, Zhi-Gang,Ren, Yang-Wu,Su, Meng,Ma, Rui,He, Qin-Cheng,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Background: Genetic polymorphisms of TP63 have been suggested to influence susceptibility to lung adenocarcinoma development in East Asian populations. This study aimed to investigate the relationship between common polymorphisms in the TP63 gene and the risk of lung adenocarcinoma, as well as interactions of the polymorphisms with environmental risk factors in Chinese non-smoking females. Methods: A case-control study of 260 cases and 318 controls was conducted. Data concerning demographic and risk factors were obtained for each subject. The genetic polymorphisms were determined by Taqman real-time PCR and statistical analyses were performed using SPSS software. Results: For 10937405, carriers of the CT genotype or at least one T allele (CT/TT) had lower risks of lung adenocarcinoma compared with the homozygous wild CC genotype in Chinese nonsmoking females (adjusted ORs were 0.68 and 0.69, 95%CIs were 0.48-0.97 and 0.50-0.97, P values were 0.033 and 0.030, respectively). Allele comparison showed that the T allele of rs10937405 was associated with a decreased risk of lung adenocarcinoma with an OR of 0.78 (95%CI=0.60-1.01, P=0.059). Our results showed that exposure to cooking oil fumes was associated with increased risk of lung adenocarcinoma in Chinese nonsmoking females (adjusted OR=1.58, 95%CI=1.11-2.25, P=0.011). However, we did not observe a significant interaction of cooking oil fumes and TP63 polymorphisms. Conclusion: TP63 polymorphism might be a genetic susceptibility factor for lung adenocarcinoma in Chinese non-smoking females, but no significant interaction was found with cooking oil fume exposure.

Sweetness or Mouthfeel: A corpus-based study of the conceptualization of taste

( Yin Zhong ),( Chu-ren Huang ) 경희대학교 언어정보연구소 2020 언어연구 Vol.37 No.3

The sensory lexicon plays a pivotal role in bridging our cognitive system to the physical world. In this role, it has been the focus of recent interdisciplinary investigations on cognition, language, culture, and their interactions. Recent studies on linguistic synesthesia and sensory modality exclusivity showed unequivocally that cross-modality usages of sensory words are the norm rather than the exception. Given the dominance of cross-modality uses, the null hypothesis that the five senses are separate but equal modules merits a closer examination. In this paper, we focus on the gustatory quality of sweetness because of its universal appeal as well as the well-attested cultural influence on the gustatory lexicon. Based on an analysis of online food reviews containing descriptions of desserts, we show that mouthfeel, a multisensory concept, is strongly preferred over sweetness. Mouthfeel is associated with words from all the sensory domains, including both sensory and abstract (e.g., mental state) concepts. The highly non-exclusive characteristic of gustatory sensation suggests that it might be the most connected sensory modality, and the cross-modality expressions indicating personal preferences further imply the subjective propensity of the gustatory sense. Our study adds to the existing literature the interrelationship among sensory modalities through language use, and further sheds light on the interactions between language, cognition, and culture.

Effect of Iron Ore Tailings Replacing Porous Basalt on Properties of Cement Stabilized Macadam

Qifang Ren,Fan Bu,Qinglin Huang,Haijun Yin,Yuelei Zhu,Rui Ma,Yi Ding,Libing Zhang,Jingchun Li,Lin Ju,Yanyan Wang,Wei Xu,Haixia Ji,Won-Chun Oh 한국재료학회 2024 한국재료학회지 Vol.34 No.6

In this paper, iron ore tailings (IOT) were separated from the tailings field and used to prepare cement stabilized macadam (CSM) with porous basalt aggregate. First, the basic properties of the raw materials were studied. Porous basalt was replaced by IOT at ratios of 0, 20 %, 40 %, 60 %, 80 %, and 100 % as fine aggregate to prepare CSM, and the effects of different cement dosage (4 %, 5 %, 6 %) on CSM performance were also investigated. CSM’s durability and mechanical performance with ages of 7 d, 28 d, and 90 d were studied with the unconfined compression strength test, splitting tensile strength test, compressive modulus test and freeze-thaw test, respectively. The changes in Ca2+ content in CSM of different ages and different IOT ratios were analyzed by the ethylene diamine tetraacetic acid (EDTA) titration method, and the micro-morphology of CSM with different ages and different IOT replaced ratio were observed by scanning electron microscopy (SEM). It was found that with the same cement dosage, the strengths of the IOT-replaced CSM were weaker than that of the porous basalt aggregate at early stage, and the strength was highest at the replaced ratio of 60 %. With a cement dosage of 4 %, the unconfined compressive strength of CSM without IOT was increased by 6.78 % at ages from 28 d to 90 d, while the splitting tensile strength increased by 7.89 %. However, once the IOT replaced ratio reached 100 %, the values increased by about 76.24 % and 17.78 %, which was better than 0 % IOT. The CSM-IOT performed better than the porous basalt CSM at 90 d age. This means IOT can replace porous basalt fine aggregate as a pavement base.

Classification of blade’s leading edge based on neural networks in adaptive machining of near-net-shaped blade

Zikai Yin,Junxue Ren,Yongshou Liang 한국정밀공학회 2021 International Journal of Precision Engineering and Vol.22 No.11

The near-net-shaped blade is adopted in the aero engine as it’s material-saving and efficient. However, the leading edge shape’s curvature is sharply changed in its machining process and the deformation trend of each cross section has slight differences. Using the traditional machining method is exhausting and time-consuming. Furthermore, it brings more errors during the whole machining process. Therefore, adaptive machining is imported in the machining of the near-net-shaped blade and the leading edge is to be reconstructed during this process. Besides, it is necessary to know whether the reconstructed leading edge is qualified. To address these two issues, a novel approach is proposed to discriminate and classify leading edges. In this paper, we trained a style transform model of generative adversarial networks with theoretical leading edges and used its discriminator network to evaluate the similarity of reconstructed leading edges we had accomplished in our previous work to establish a standard for the qualified reconstructed leading edge. Then, as the curvature of the near-net-shaped blade changes sharply and has complex features, which requires high accuracy of classification, different DenseNet models were adopted to classify whether these reconstructed images are qualified. We experimented on our LDEG dataset and the highest accuracy on the test set was 88.7%. The experiment results demonstrated that the proposed method is effective in evaluating and classifying leading edges in the machining process.

Alloy and Core-Shell Nanoclusters Formed by Sequential Ion Implantation and Thermal Annealing

Feng Ren,Chang-Zhong Jiang,Chang Liu,Jian-Bo Wang,Yin Shi 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1

Ag-Cu alloy nanoclusters have been formed by sequential ion implantation. As the as-implanted sample is annealed in a reducing atmosphere, the optical absorption spectrum displays a new shoul- der peak. Transmission electron microscopy bright-¯eld image, selected area electron diraction pattern and high-angle annular dark ¯eld scanning transmission electron microscopy image analy-ses show that core-shell nanoclusters have been fabricated. The evolution of core-shell nanoclusters at elevated temperature was also studied.

Yunbao Yin,Bo Luo,Hongbin Ren,Qiang Fang,Chunsheng Zhang 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.12

The control performance of the vehicle will degrade due to the uncertain dynamics between the mathematical nominal plant description and the actual physical system. A robust control scheme is designed for an active suspension system so as to improve the system control performance. In the design of a robust control scheme, the real parametric uncertainties, as well as the structural uncertainty and time delay of the actuator, are taken into account, which is more realistic than the traditional control methods. Robustness performance and stability of the system are investigated and discussed in the paper. The μ synthesis controller is designed and compared with the H∞ control algorithm as well as the traditional passive suspension system. The control performance is validate under two typical road excitation conditions including the random road and the speed bump road. Simulation results show the effectiveness of the proposed control schemes compared to a H∞ approach.
