Min Luo,Juanjuan Feng,Li Guan,Baolin Sun,Hua Chen 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.3

Network coding in Mobile Ad hoc Network (MANET) is well-known in reducing delay, increasing throughput, and improving transmission reliability. While the data throughput capacity of MANETs is unknown, the scaling of capacity with the number of nodes has recently received increasing attention. This paper proposes a Complex Field Network Coding-based Multipath Routing in MANETs (CFNC-MRM). The performance of this routing method is studied using NS2 and evaluated in terms of the packet overhead, packet delivery ratio, and packet loss ratio when a packet is transmitted. Simulation shows that the CFNC-MRM is efficient, providing reliable multipath, promising and applicable in MANETs.

Xuan Yu,Shouyuan Wu,Juanjuan Zhang,Yue Hu,Meng Luo,Hongmei Zhao,Xuping Song,Yaolong Chen,Xiaohui Wang 한국한의학연구원 2023 Integrative Medicine Research Vol.12 No.2

Clinical practice guidelines in Traditional Chinese Medicine (CPG-TCM) is the recommendation that aims to provide the best service to users by identifying and summarizing the rules of prevention, diagnosis, treatment, rehabilitation, and regression of diseases based on systematic reviews of evidence and balancing the advantages and disadvantages of different interventions for clinical questions of Traditional Chinese Medicine. Over the past 30 years, the concept and methods of evidence-based medicine have had a significant impact on the development of clinical practice guidelines in Western Medicine (CPG-WM), and their standardized guideline development methods are being adapted and used in the development of CPG-TCM. However, the quality of CPG-TCM is far from CPG-WM, and the methodological system for developing CPG-TCM is not yet fully established. Therefore, this study aims to explore the methodological differences between CPG-TCM and CPG-WM and to inform the development of high-quality CPGTCM.

Contribution of Shear Reinforcements and Concrete to the Shear Capacity of Interfaces between Concretes Cast at Different Times

Jie Liu,Yangmin Bu,Juanjuan Chen,Qing Wang 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.6

Currently, shear transfer models have diverse assumptions about the contribution of shear reinforcements and concrete to the shear capacity of interfaces between concretes cast at different times (that is, cold joints). Furthermore, the knowledge about the effect of high–strength shear reinforcements (HSSR) having a nominal yield strength exceeding 414 MPa (60 ksi), is still limited. This study aims to determine the extent to which shear reinforcements and concrete contribute to the shear capacity of cold joints and explore the effect of HSSR on shear transfer behavior. To this end, nine cold joint push–off specimens were tested to investigate the effects of yield strength of shear reinforcement (YSSR) and concrete compressive strength (CCS) on the interface shear strength and stiffness. In addition, code provisions evaluation was used to identify the degree of concrete contribution, based on a database of 108 cold joint push–off test results established in this study. Test results indicate that the increase of YSSR (rising from 400 MPa to 600 MPa) has no evident effect on the shear strength and stiffness of cold joints, whereas the increase of CCS can significantly increase them. Moreover, when CCS rises from 20 MPa to 50 MPa, the interface shear capacity of push–off specimens increases by approximately 110%, i.e., from 103.5 kN to 217.5 kN. Hence, concrete has a considerable contribution, whereas the contribution of shear reinforcements is not as great as expected. Code provisions evaluation results also indicate that concrete considerably contributes to the shear capacity in the form of cohesion. On the basis of these findings and current design equations, a shear capacity equation, which accounts for the effect of CCS and the limited participation of shear reinforcements, is proposed. This equation is found to provide reasonable prediction of cold joint shear capacity, especially for the cold joint composed of high–strength concrete.

Intensive potato continuous cropping (IPCC) results in low potato yields compared with non-intensive potato continuous cropping (PCC) and potato-maize rotation (PMRC). However, it is still unclear whether the degree of potato continuous cropping obstacle is related to the soil environment formed by the previous crop. To investigate the effect of planting potatoes and planting maize after harvesting the spring potatoes on soil chemical properties and soil microbial community structure, an experiment was carried out in the same origin soil environment over a period of seven years: (a) PCC, i.e., spring planting; (b) IPCC, i.e., autumn and spring planting (IPCC); (c) PMRC, i.e., spring potatoes and summer maize (PMRC), and (d) fallow (CK). We confirmed that the potato yield under PMRC was significantly higher than that under PCC and IPCC. Under IPCC, soil total phosphorus content was significantly higher than other treatments, whereas ammonium nitrogen content was the lowest. Compared with PCC and IPCC, PMRC had a higher ammonium nitrogen content and lower total phosphorus content. The significantly different fungal taxa in IPCC (Glomerellales, Plectosphaerella, Thelebolales) may threaten the health of the plant and positive correlated with soil total phosphorus, while other microbial taxa in PMRC (Bacillales, Polythrincium, Helotiales) can mainly promotes plant nitrogen uptake and protects plants against diseases. The PMRC-promoting taxa were positively correlated with the ammonium nitrogen content and negative correlated with soil total phosphorus content. In summary, the cropping systems might have affected potato yields by changed soil microorganism community structures – especially fungal community structures – and by the chemical properties of the soils that also depends on microbes.

Piezo channels in the urinary system

Li Xu,Hu Junwei,Zhao Xuedan,Li Juanjuan,Chen Yuelai 생화학분자생물학회 2022 Experimental and molecular medicine Vol.54 No.-

The Piezo channel family, including Piezo1 and Piezo2, includes essential mechanosensitive transduction molecules in mammals. Functioning in the conversion of mechanical signals to biological signals to regulate a plethora of physiological processes, Piezo channels, which have a unique homotrimeric three-blade propeller-shaped structure, utilize a cap-motion and plug-and-latch mechanism to gate their ion-conducting pathways. Piezo channels have a wide range of biological roles in various human systems, both in vitro and in vivo. Currently, there is a lack of comprehensive understanding of their antagonists and agonists, and therefore further investigation is needed. Remarkably, increasingly compelling evidence demonstrates that Piezo channel function in the urinary system is important. This review article systematically summarizes the existing evidence of the importance of Piezo channels, including protein structure, mechanogating mechanisms, and pharmacological characteristics, with a particular focus on their physiological and pathophysiological roles in the urinary system. Collectively, this review aims to provide a direction for future clinical applications in urinary system diseases.

Xiaonan Tang,Yueyun Li,Runhai Chen,Fanlian Min,Juanjuan Yang,Yunhui Dong 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.1

Loofah fiber, an economical adsorbent material, was first developed for the methyl green (MG) removalfrom aqueous solutions. The loofah fibers were characterized by SEM, FTIR, N2-BET and the potentiometric titration. The pH, contact time and temperature were examined extensively. The adsorption of MG on loofah fiber increasedvery quickly in the pH range 3.0 to 7.0, remaining a high level at pH>7.0. The kinetics of adsorption of MG on theloofah fiber was proved to coincide with pseudo-second-order kinetic models (r2>0.99) very well. Langmuir isothermwas demonstrated to fit the experimental data better than Freundlich isotherm model. Monolayer adsorption capacityincreased with the increase of temperature. Thermodynamic constants were evaluated, and the results indicated thatMG adsorption onto loofah fiber was feasible, spontaneous and endothermic. The high removal efficiency of MG onloofah fiber suggested that the loofah fiber was suitable material in MG pollution cleanup.

Ruilian Xiu,Jie Jia,Qing Zhang,Fengjiao Liu,Yaxin Jia,Yuanyuan Zhang,Beibei Song,Xiaodan Liu,Jingwei Chen,Dongyang Huang,Fan Zhang,Juanjuan Ma,Honglin Li,Xuan Zhang,Yunyun Geng 대한약리학회 2023 The Korean Journal of Physiology & Pharmacology Vol.27 No.6

Transmembrane protein TMEM16A, which encodes calcium-activated chloride channel has been implicated in tumorigenesis. Overexpression of TMEM16A is associated with poor prognosis and low overall survival in multiple cancers including lung adenocarcinoma, making it a promising biomarker and therapeutic target. In this study, three structure-related sesquiterpene lactones (mecheliolide, costunolide and dehydrocostus lactone) were extracted from the traditional Chinese medicine Aucklandiae Radix and identified as novel TMEM16A inhibitors with comparable inhibitory effects. Their effects on the proliferation and migration of lung adenocarcinoma cells were examined. Whole-cell patch clamp experiments showed that these sesquiterpene lactones potently inhibited recombinant TMEM16A currents in a concentration- dependent manner. The half-maximal concentration (IC50) values for three tested sesquiterpene lactones were 29.9 ± 1.1 μM, 19.7 ± 0.4 μM, and 24.5 ± 2.1 μM, while the maximal effect (Emax) values were 100.0% ± 2.8%, 85.8% ± 0.9%, and 88.3% ± 4.6%, respectively. These sesquiterpene lactones also significantly inhibited the endogenous TMEM16A currents and proliferation, and migration of LA795 lung cancer cells. These results demonstrate that mecheliolide, costunolide and dehydrocostus lactone are novel TMEM16A inhibitors and potential candidates for lung adenocarcinoma therapy.
