| 1 | Intelligent Task Offloading and Collaborative Computation over D2D Communication显示文摘In this paper,the problem of computation offloading in the edge server is studied in a mobile edge computation(MEC)-enabled cell networks that consists of a base station(BS)integrating edge servers,several terminal devices and collaborators.In the considered networks,we develop an intelligent task offloading and collaborative computation scheme to achieve the optimal computation offloading.First,a distance-based collaborator screening method is proposed to get collaborators within the distance threshold and with high power.Second,based on the Lyapunov stochastic optimization theory,the system stability problem is transformed into a queue stability issue,and the optimal computation offloading is obtained by solving these three sub-problems:task allocation control,task execution control and queue update,respectively.Moreover,rigorous experimental simulation shows that our proposed computation offloading algorithm can achieve the joint optimization among the system efficiency,energy consumption and time delay compared to the mobility-aware and migration-enabled approach,Full BS and Full local. | Cuili Jiang Tengfei Cao Jianfeng Guan | 2021 | China Communications2021，18，3： | 3 |
| 2 | Stabilized multifunctional phase change materials based on carbonized Cu-coated melamine foam/reduced graphene oxide framework for multiple energy conversion and storage显示文摘The leakage of organic phase change materials(OPCMs)at temperatures above their melting point severely limits their large-scale application.The introduction of porous supports has been identified as an efficient leakageproofing method.In this study,a novel carbonized Cu-coated melamine foam(MF)/reduced graphene oxide(rGO)framework(MF/rGO/Cu-C)is constructed as a support for fabricating stabilized multifunctional OPCMs.MF serves as the supporting material,while rGO and Cu act as functional reinforcements.As a thermal energy storage material,polyethylene glycol(PEG)is encapsulated into MF/rGO/Cu-C through a vacuum-assisted impregnation method to obtain PEG@MF/rGO/Cu-C composite with excellent comprehensive performance.PEG@MF/rGO/Cu-C exhibits high phase change enthalpies of 148.3 J g^(-1)(melting)and 143.9 J g^(-1)(crystallization),corresponding to a high energy storage capability of 92.7%.Simultaneously,MF/rGO/Cu-C endues the composite with an enhanced thermal conductivity of 0.4621Wm^(-1) K^(-1),which increases by 463%compared to that of PEG@MF.Furthermore,PEG@MF/rGO/Cu-C displays great light-to-thermal and electric-to-thermal conversion capabilities,thermal cycle stability,light-tothermal cycle stability,and shape stability,showing promising application prospects in different aspects. | Zhicong Hu Yongjin Zou Cuili Xiang Lixian Sun Fen Xu Menghe Jiang Sensen Yu | 2022 | Carbon Energy2022，4，6： | 0 |
| 3 | How does Street Vending Economy Help Rural to Urban Migrants Integrate into Cities?显示文摘Street vending is a form of informal economy.The main participants of street vending economy consist of exploited workers,rural-urban migrants who are in low level of socioeconomic households,common workers,and some individual households.Most of the studies and articles have explored how to regulate the street vending economy and how to facilitate the relationship between vendors and city authorities,but the important constitute of street vending economies,rural migrants,has received little attention from scholars and there is little research about it.What role does street vending economy play in the lives of this segment of this population which itself faces a number of challenges in migrating and integrating into the city?We have found out that street vending functions as a platform which helps these people to better integrate into the cities.Through desktop research and case studies,this paper explores how street vending economy helps rural to urban migrants integrate into the city from four perspectives:identity integration,integrating in economic level,integrating in social level,and females'empowerment. | Qianxun Jiang Cuili Luan | 2021 | Macro Management & Public Policies2021，3，3： | 0 |

| 5 | Lipopolysaccharide-induced podocyte injury is regulated by calcineurin/NFAT and TLR4/MyD88/NF-κB signaling pathways through angiopoietin-like protein 4显示文摘Podocyte injury is an important cause of proteinuria.Angiopoietin-like protein 4(Angptl4)is a secreted glycoprotein and has a role in proteinuria.However,the exact role of Angptl4 in podocyte injury and its upstream regulators has not been clarified.In this study,we used lipopolysaccharide(LPS)-induced mice and cultured podocytes as podocyte injury models.Our results indicated that LPS increased the expression of podocyte Angptl4 in vivo and in vitro.Furthermore,we showed that Angptl4 overexpression deteriorated LPS-induced podocyte injury by inducing podocyte cytoskeleton rearrangement,reducing the expression of synaptopodin while Angptl4 knockdown alleviated LPS-induced podocyte injury.In addition,we found that inhibitors and siRNA targeting TLR4/MyD88/NF-κB signaling inhibited the upregulation of Angptl4 in LPS-induced podocytes.Moreover,inhibitors and siRNA targeting calcineurin/NFAT signaling also relieved LPS-induced Angptl4 expression and podocyte injury in vivo and in vitro.Taken together,our study has elucidated that both of the TLR4/MyD88/NF-κB and calcineurin/NFAT signaling mediate the upregulation of Angptl4 in LPS-induced podocytes,which has important implications for further understanding the molecular mechanism of LPS-induced podocyte injury. | Xiujin Shen Chunhua Weng Yucheng Wang Cuili Wang Shi Feng Xiayu Li Heng Li Hong Jiang Haibing Wang Jianghua Chen | 2022 | Genes & Diseases2022，9，2： | 0 |
| 6 | Telomere shortening in patients on long-term hemodialysis显示文摘Background:Leukocyte telomere length shortening is a characteristic of premature senescence,a process that can be accelerated by oxidative stress.In general,patients with end-stage renal disease undergoing regular hemodialysis(HD)are repeatedly exposed to oxidative stress.Patients undergoing HD tend to have cardiovascular diseases associated with oxidative stress and inflammation.Therefore,we assumed that telomere length is associated with HD vintage and the degree of vascular calcification.Methods:A total of 144 patients undergoing regular HD before kidney transplantation and 62 patients on hemodialysis,but not undergoing kidney transplantation,were enrolled.We measured common laboratory values,such as calcium,phosphate,and hemoglobin levels,and assessed the degree of vascular calcification in the patients.The leukocyte telomere length was measured using reverse transcription polymerase chain reaction,and Spearman correlation was used for correlation analysis.Results:The leukocyte telomere length was negatively associated with age(rho=-0.306,P<0.01);it was shorter in middle-aged patients than in young patients(13.48±4.80 vs.15.86±4.51,P<0.01).The telomere length was significantly different among patients aged 52-74 years in groups with different HD vintages.Additionally,the telomere length was positively associated with serum hemoglobin(Hb)levels in all patients(rho=0.290,P<0.01).There was a significant difference among patients divided into three groups according to the degree of anemia(17.09±5.64 vs.14.40±4.07 vs.13.99±3.95,P<0.01).Further,a significant difference was observed in the telomere length among patients with different degrees of vascular calcification(16.79±4.91 vs.13.61±2.82 vs.14.62±3.63 vs.10.71±3.74,P<0.01).The telomere length was shorter in the patients on hemodialysis who did not receive a kidney transplant than in the surgical patients(8.12±1.83 vs.14.33±4.63,P<0.01).Conclusion:This study demonstrated that the telomere length was significantly correlated with HD vintage in patients of a certain age group.The telomere length was shorter in patients on hemodialysis who matched for age and dialysis vintage with kidney transplant patients.It was also associated with vascular calcification and serum Hb levels in all patients undergoing HD. | Yucheng Wang Siyu Chen Shi Feng Cuili Wang Hong Jiang Song Rong Haller Hermann Jianghua Chen Ping Zhang | 2021 | Chronic Diseases and Translational Medicine2021，7，4： | 0 |
