Minimizing power consumption in bandwidth limited optical traffic grooming networks is presented as a two-objective optimization problem. Since the main objective is to route a connection, the network throughput is maximized first, and then the minimum power consumption solution is found for this maximized throughput. Both transparent IP over WDM (Tp-IPoWDM) and translucent IP over WDM (Tl-IPoWDM) network may be applied to examine such bi-objective algorithms. Simulations show that the bi-objective algorithms are more energy-efficient than the single objective algorithms where only the throughput is optimized. For a Tp-IPoWDM network, both link based ILP (LB-ILP) and path based ILP (PB-ILP) methods are formulated and solved. Simulation results show that PB-ILP can save more power than LB-ILP because PB-ILP has more path selections when lightpath lengths are limited. For a Tl-IPoWDM network, only PB-ILP is formulated and we show that the Tl-IPoWDM network consumes less energy than the Tp-IPoWDM network, especially under a sparse network topology. For both kinds of networks, it is shown that network energy efficiency can be improved by over-provisioning wavelengths, which gives the network more path choices.

ZHOU HUIZHUO,Yang, Zijian 한국비즈니스학회 2024 비즈니스융복합연구 Vol.9 No.1

The purpose of this study is to analyze the impact of customer participation on customer behavior intention under the O2O mode of fast fashion brands. This study collected data from 232 customers with experience using fast fashion brands O2O mode. The results showed that customer participation (advance preparation, information sharing and interpersonal interaction) and the relationship between functional value had a positive effect. Customer participation (advance preparation, information sharing, cooperative behavior and interpersonal interaction) and the relationship between emotional value had a positive effect. Customer experiential value (functional value and emotional value) had a significant positive impact on customer behavior intentions (repurchase intention and word-of-mouth intention). Based on the research findings, this study suggests that fast fashion brand O2O e-commerce enterprises should recognize the necessity of close interaction and collaboration with customers. It is essential to produce products or services that truly meet customers' needs and advocate the customer-centric business philosophy.

PURPOSE: In this study, high content ligustilide plant extract was supplemented to monitor the changes of physical fitness and physiological function of athletes, and to explore the effect of ligustilide plant extract on physical function and physical fitness of athletes. METHODS: Thirty five high-level basketball players from Zhengzhou University were selected and divided into two groups randomly: nutritional supplement group (S, n = 18) and control group (C, n=17). This study was approved by the Ethics Committee of Zhengzhou University. Informed consent was obtained from each subject. The intervention period was 8 weeks, six days per week. The training method adopted the small cycle plate training scheme. We measured changes of the scores of rating of perceived exertion (RPE), physical fitness test (15m running, 30m running, 400m running) and routine blood test (mainly including red blood cell count, hemoglobin concentration and average erythrocyte hemoglobin concentration, etc.) before and after training. RESULTS: In group S, the percentage of RPE (grade 6-11) and RPE (grade 12-18) before experiment was 37.5% and 62.5%. After 8 weeks of experiment, 62.5% of RPE (grade 6-11) and 37.5% of RPE (grade 12-18). In group C, 14% of RPE (grade 6-11), 86% of slight RPE (grade 12-18), and 100% of RPE (grade 12-18) after 8 weeks of experiment. It was found that after 8 weeks of training, the number of red blood cells, the concentration of hemoglobin and the average concentration of red blood cell hemoglobin in group S were significantly higher than those before the experiment (p <0.05). According to the comparison of the physical fitness test results of the athletes in group S, it was found that the performance of 400m after 4 weeks and 8 weeks was significantly higher compared with pre-experiment (p<0.05). The changes of 30m and 15m were not significant different (p>0.05). The 400-meter test performance of athletes in group C was significantly higher than that before the experiment only after 8 weeks of training (p<0.05). CONCLUSIONS: Ligustilide supplementation can increase the number of red blood cell and hemoglobin concentration of athletes and has a positive impact on the physical fitness of athletes and the recovery of fatigue.

Participates in actin remodeling through Rac and receptor endocytosis via Rab5. Here, we used yeast two-hybrid system with Eps8 as bait to screen a human brain cDNA library. ITSN2 was identified as the novel binding factor of Eps8. The interaction between ITSN2 and Eps8 was demonstrated by the in vivo co-immunoprecipitation and colocalization assays and the in vitro GST pull-down assays. Furthermore, we mapped the interaction domains to the region between amino acids 260-306 of Eps8 and the coiled-coil domain of ITSN2. In addition, protein stability assays and immunofluorescence analysis showed ITSN2 overexpression induced the degradation of Eps8 proteins, which was markedly alleviated with the lysosome inhibitor NH4Cl treatment. Taken together, our results suggested ITSN2 interacts with Eps8 and stimulates the degradation of Eps8 proteins. [BMB reports 2012; 45(3): 183-188]

Bin Zhang,Yuanfu Zhou,Xuefu Zhang,Zijian Wang,Wei Yang,Yixuan Ban 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.4

Grouting technology is an important method that has been widely adopted for the crack repair of tunnel lining, but the diffusion law of grouting slurry is still uncertain in tunnel lining cracks. For the sake of exploring the grouting diffusion law of tunnel lining cracks, this paper investigated the grouting diffusion shape and the relation between the diffusion radius and time with different crack widths in tunnel lining which by means of laboratory experiments and statistical analysis. Meanwhile, the diffusion equation of grouting in lining cracks has been established on basis of the grouting diffusion shape and experimental data. Furthermore, it is analyzed the correlation between the experimental values and the calculated values. The results revealed that the diffusion shape can be divided into a circular zone, excessive zone, and elliptical zone in the tunnel lining cracks, and the calculated values of the equation of grouting diffusion are highly correlated with the experimental values. Additionally, it is shown that the diffusion equation can accurately describe the relationship between diffusion radius and time of grouting in tunnel lining cracks. The study results would provide a theoretical basis for the prediction of diffusion radius on grouting repair for tunnel lining cracks.

Effect of kaolin additive on PM_2.5 reduction during pulverized coal combustion: Importance of sodium and its occurrence in coal

Si, Junping,Liu, Xiaowei,Xu, Minghou,Sheng, Lei,Zhou, Zijian,Wang, Chao,Zhang, Yang,Seo, Yong-Chil Elsevier 2014 APPLIED ENERGY Vol.114 No.-

<P><B>Abstract</B></P> <P>Little work has been performed on the importance of sodium and its occurrence in coal to PM<SUB>2.5</SUB> (particles less than 2.5μm in aerodynamic diameter) reduction by kaolin during O<SUB>2</SUB>/N<SUB>2</SUB> combustion and O<SUB>2</SUB>/CO<SUB>2</SUB> combustion at high temperatures. In this study, the combustion experiment of a treated low-sodium coal with sodium aluminosilicate additive was conducted in a lab-scale drop tube furnace (DTF) at 1500°C to reveal the contribution of mineral melting and coalescence to PM<SUB>2.5</SUB> reduction. Meanwhile, two typical Na-loaded coals (in which the sodium was loaded in the form of NaCl and sodium carboxylate, respectively) with kaolin added were also burnt under O<SUB>2</SUB>/N<SUB>2</SUB> and O<SUB>2</SUB>/CO<SUB>2</SUB> atmospheres to investigate the effect of interaction between kaolin and different chemical form sodium on PM<SUB>2.5</SUB> reduction. The results show that sodium aluminosilicate is able to promote the migration of PM<SUB>0.5–2.5</SUB> (particles in aerodynamic diameter of 0.5–2.5μm) to form coarse particles. Due to the stronger reactivity of sodium carboxylate reacting with kaolin than that of NaCl, PM<SUB>0.2–0.5</SUB> (particles in aerodynamic diameter of 0.2–0.5μm) decreases more significantly in the combustion when adding kaolin into the NaAc-loaded coal than into NaCl-loaded coal. In addition, the PM<SUB>0.2–0.5</SUB> reduction in O<SUB>2</SUB>/CO<SUB>2</SUB> combustion is lower than that in O<SUB>2</SUB>/N<SUB>2</SUB> combustion owing to the less vaporization of metals and the slower diffusion rate of vapors in the O<SUB>2</SUB>/CO<SUB>2</SUB> atmosphere in comparison to those in the O<SUB>2</SUB>/N<SUB>2</SUB> atmosphere. The mineral coalescence varied in interactions of kaolin with NaAc and NaCl. Besides, the PM<SUB>0.5–2.5</SUB> emission differed as a result of differences in coal characteristic and the atmosphere, and this would cause the difference of collision frequency between particles and additive. With the joint actions of mineral coalescence and particle collision, the NaAc-loaded coal has a higher PM<SUB>0.5–2.5</SUB> reduction by kaolin than NaCl-loaded coal, especially under the O<SUB>2</SUB>/N<SUB>2</SUB> combustion. An expression describing the relationship of PM<SUB>0.5–2.5</SUB> reduction, mineral coalescence and particle collision was fitted and it is found that the mineral coalescence has a stronger influence than particle collision on PM<SUB>0.5–2.5</SUB> reduction by kaolin.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The sodium aluminosilicate plays an important role in PM<SUB>2.5</SUB> reduction by kaolin. </LI> <LI> The capability of kaolin to reduce PM<SUB>2.5</SUB> depends on the sodium occurrence in coals. </LI> <LI> The effect of kaolin on PM<SUB>2.5</SUB> reduction becomes weaker during O<SUB>2</SUB>/CO<SUB>2</SUB> combustion. </LI> <LI> Particle collision may be taken into consideration for PM<SUB>2.5</SUB> reduction. </LI> </UL> </P>
