Driver identification in intelligent transport systems has immense demand,considering the safety and convenience of traveling in a vehicle.The rapid growth of driver assistance systems(DAS)and driver identification system propels the need for understanding the root causes of automobile accidents.Also,in the case of insurance,it is necessary to track the number of drivers who commonly drive a car in terms of insurance pricing.It is observed that drivers with frequent records of paying“fines”are compelled to pay higher insurance payments than drivers without any penalty records.Thus driver identification act as an important information source for the intelligent transport system.This study focuses on a similar objective to implement a machine learning-based approach for driver identification.Raw data is collected from in-vehicle sensors using the controller area network(CAN)and then converted to binary form using a one-hot encoding technique.Then,the transformed data is dimensionally reduced using the Principal Component Analysis(PCA)technique,and further optimal parameters from the dataset are selected using Whale Optimization Algorithm(WOA).The most relevant features are selected and then fed into a Convolutional Neural Network(CNN)model.The proposed model is evaluated against four different use cases of driver behavior.The results show that the best prediction accuracy is achieved in the case of drivers without glasses.The proposed model yielded optimal accuracy when evaluated against the K-Nearest Neighbors(KNN)and Support Vector Machines(SVM)models with and without using dimensionality reduction approaches.

Precise and controlled drug delivery to treat periodontitis in patients with diabetes remains a significant clinical challenge.Nanoparticle-based drug delivery systems offer a potential therapeutic strategy;however,the low loading efficiency,non-responsiveness,and single effect of conventional nanoparticles hinder their clinical application.In this study,we designed a novel self-assembled,dual responsive,and dual drug-loading nanocarrier system,which comprised two parts:the hydrophobic lipid core formed by 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine-Poly(ethylene glycol)(DSPE-PEG)loaded with alpha-lipoic acid(ALA);and a hydrophilic shell comprising a poly(amidoamine)dendrimer(PAMAM)that electrostatically adsorbed minocycline hydrochloride(Mino).This unique design allows the controlled release of antioxidant/ALA under lipase stimulation from periodontal pathogens and antimicrobial/Mino under the low pH of the inflammatory microenvironment.In vivo and in vitro studies confirmed that this dual nanocarrier could inhibit the formation of subgingival microbial colonies while promoting osteogenic differentiation of cells under diabetic pathological conditions,and ameliorated periodontal bone resorption.This effective and versatile drug-delivery strategy has good potential applications to inhibit diabetes-associated periodontal bone loss.

经过了天宝战争及随后的军事扩张,位于唐代中国西南边疆的南诏国在较短的时期先后建置了拓东、开南、镇西、宁北四个王国边境的重要治所城镇,其中开南城与拓南城的考释自元末以后已多现舛误,造成了史实混淆。事实上,唐代中国西南边疆的拓南城与开南城确为南诏国开拓建置的两座新城,而非“开南亦称拓南”,元末以后,“拓南”名号逐渐隐没于原地,同时被移置于“开南”地望,开始混用一起。厘清二城地望考释,不难发现拓南城的建置开拓了南诏国的西南辖境,开南城的建置开拓了南诏国的南境,从而把中原的“郡县制”文化辐射到了西南边境区域,客观上促进了区域内各民族的交往交流交融,奠定了唐代及后世中国西南边境、边界形成和发展的历史基础,为唐代中国西南边境区域各民族铸牢中华民族共同体意识做出了贡献。

Comparison of Success Rate and Radiological Bone Loss in Patients with Mini-Implant versus Conventional-Sized Implant Removable Prostheses: A Meta-Analysis

引用

Open Journal of Stomatology 2021年第2期11卷 65-76页

Abubaker yuzhou li Sheng Yang College of Stomatology Chongqing Medical University Chongqing China College of Stomatology Chongqing Medical University Chongqing Key Laboratory of Oral Diseases and Biomedical Sciences Chongqing China College of Stomatology Chongqing Medical University Chongqing Municipal Key Laboratory of Oral Biomedical Engineering of Higher Education Chongqing China

Background: The objective of this meta-analysis was to assess whether mini-implants have added benefit in terms of implants success rate and average bone loss over conventional-sized implants after one year of follow-up. Methods: An electronic search of randomized clinical trials was conducted in MEDLINE (via PubMed), Cochrane Central Register of Clinical Trials (CENTRAL) and Web of Science for studies including complete or partial edentulous patients requiring two or four mini-implants or conventional/ standard-sized implants in the maxilla or mandible for implant-supported removable prostheses who completed 12 months of follow-up. Results: The search provided 194 unique articles which were screened for title and abstract. Screening generated 12 articles which went through full-text analysis using eligibility criteria, and 4 articles were included for meta-analysis. Meta-analysis of these studies indicated a non-significant difference in the success rate between the two interventions (OR = 1.69 [0.74, 3.85;p = 0.21]). Bone loss estimates resulted in a significant bone reduction (Mean Difference = -0.74 [-0.95, -0.53;p - with two conventional-sized implants, the estimates were non-significant (Mean Difference = -0.24 [-0.69, 0.20;p = 0.29]). Conclusion: The current evidence does not provide solid evidence of the benefits of one intervention over the other. More studies with follow-up times of 10 and more years are needed as current studies have described the short-term outcomes.

Ribonucleotide reductase M2(RRM2)is a small subunit in ribonucleotide reduc-tases,which participate in nucleotide metabolism and catalyze the conversion of nucleotides to deoxynucleotides,maintaining the dNTP pools for DNA biosynthesis,repair,and replication.RRM2 performs a critical role in the malignant biological behaviors of cancers.The structure,regulation,and function of RRM2 and its inhibitors were discussed.RRM2 gene can produce two transcripts encoding the same ORF.RRM2 expression is regulated at multiple levels during the processes from transcription to translation.Moreover,this gene is associated with resistance,regulated cell death,and tumor immunity.In order to develop and design inhibitors of RRM2,appropriate strategies can be adopted based on different mechanisms.Thus,a greater appreciation of the characteristics of RRM2 is a benefit for understanding tumorigenesis,resistance in cancer,and tumor microenvironment.Moreover,RRM2-targeted therapy will be more attention in future therapeutic approaches for enhancement of treatment effects and amelioration of the dismal prognosis.

Fairness-based joint call admission control for heterogeneous wireless networks:an SMDP approach

引用

Science China(Information Sciences) 2014年第8期57卷 66-77页

作者： liU GuoQing SHENG Min WANG XiJun li Ying li yuzhou State Key Laboratory of Integrated Service Networks Xidian University

In heterogeneous wireless networks,both terminal heterogeneity and network heterogeneity give rise to the fairness problem of resource allocation.Due to the capability of exploiting the resources of multiple networks,the behavior of multi-mode terminals will have a great effect on single-mode terminals,and this influence becomes more severe when considering the different demands of different traffic.In this article,we propose a novel joint call admission control(JCAC)scheme to address this problem.The JCAC problem is modeled as a semi-Markov decision process(SMDP)with the aim of maximizing the average network revenue under the constraints of the fairness among different terminals and traffic classes.Based on the SMDP,we design an algorithm to achieve a good tradeoff between revenue and fairness by dynamically adjusting the threshold of fairness constraints imposed on heterogeneous terminals.Simulation results show that the proposed scheme can significantly improve the fairness among heterogeneous terminals and guarantee the priority and fairness among different traffic classes with little loss of network revenue compared with other schemes.

End-to-end delay estimation for multi-hop wireless networks with random access policy

引用

Science China(Information Sciences) 2014年第6期57卷 141-153页

作者： JIAO WanGuo SHENG Min SHI Yan li yuzhou The State Key Lab of Integrated Services Networks Xidian University

End-to-end delay analysis is an important element of network performance analysis in multi-hop wireless networks.In this paper,we propose an analytical model for estimating the end-to-end delay performance of wireless networks employing a random access policy for managing node’transmissions on shared channels with time-varying capacity.To obtain the closed form expression,a new concept of residual effective capacity is presented using the definitions of effective bandwidth theory and effective capacity theory.This allows us to calculate the cumulative distribution function of the queuing delay.Based on this concept,we derive a formula to calculate the average end-to-end delay for multi-hop wireless networks,with the result including the effect of a random access protocol,which has not previously been considered.Finally,we validate our analysis through simulations and provide an example application for our results.
