<P>Herein, a three-dimensional (3D) reduced graphene oxide hydrogel (rGOH) was fabricated by crosslinking ethylene diamine (EDA) and the functional groups of GO in the presence of one-dimensional (1D) Ag nanowires (NWs). The Ag NWs increased the electrical conductivity and the pore size of the final 3D structures. The capacitance of Ag-rGOH (369 F g(-1)) was 1.7 times higher than that of EDA-rGOH (218 F g(-1)) and 1.3 times higher than that of a physically mixed sample with the same Ag content. Moreover, the Ag-rGOH electrode also exhibits excellent long-term stability with a capacitance retention of more than 90% over 1,000 cycles and a high energy of 2.2 Wh kg(-1) at 900 W kg(-1).</P>

Objective Stereotactic Body Radiation Therapy (SBRT) was indicated for early-stage non-small cell lung cancer (NSCLC) patients inoperable. The purpose of the study was evaluated the result of SBRT in stage I NSCLC patients (T1-2aN0M0) with peripheral tumors. Methods Prospective, follow-up 23 patients with stage T1-2aN0M0 NSCLC with peripheral tumor, who were received SBRT, followup and evaluated from January, 2015 to January, 2020. The primary endpoints were Objective Response Rate (ORR), Disease Control Rate (DCR), Progression Free Survival (PFS), the second endpoints were Overall Survival (OS) and Toxicity. Results The average age was 65.13 years-old, the mean of diameter was 3.31cm, the mean of SUVmax value was 7.77. The stage of the tumor is mostly T2a (60,9%). The median of follow-up was 26 months, ORR was 91.3%, DCR was 95.7%. The median PFS was 26 months, median OS was 58 months, the ratio of OS in 1 year, 2 years, 3 years, 4 years, 5 years were 95.7%, 65.2%, 39.1%, 26.1% and 17.4%, respectively. The common of adverse events was pneumonitis due to SBRT at 9 patients, but mainly was grade 1, no patients have pneumonitis grade 4 and 5. No clinically significant changes in pulmonary function following SBRT for earlystage NSCLC. Conclusion SBRT was a good option for patients with stage I NSCLC, there was no significant difference in survival between patients who refused surgery and those who have medical inoperable and this is a safe treatment for patients.
Application of Independent Finance Certification Agency in the Decision Process of Vendor Selection
Luan Chunxiao 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.5
This paper introduces independent finance certification agency to supervise the vendor selection process under the circumstance of the dynamic and incomplete information market. Using the signaling theory under unsymmetric information of game theory, a multidimension signaling model of the strategic choice is established. The game model is set up and the equilibrium calculated out following the description of the key elements of the buyer and vendor in above market. Upon separating equilibrium, the provider dispatches the signal stands for his actual category to maintain the performance of the market. Upon pool equilibrium, the inefficient provider rather than efficient one occupies the core position which results in loss of the latter. Case result shows that the buyer can adopt the signals from the Independent finance certification agency as a significant element when making decision. As a result the introduction of independent finance certification agency can effectively and efficiently supervise the vendor selection process in incomplete information market.

<P><B>Abstract</B></P> <P>Unlike the stretchable physical sensors such as stretchable pressure sensors, strain sensors, and temperature sensors, few works have been reported on the stretchable gas sensors. This study presents that stretchable gas sensors can be fabricated by decorating reduced graphene oxide/silver nanowires (rGO/AgNWs) hybrids on the porous polyurethane (PU) sponges using a facile dip-coating method. The sensors show good room-temperature responses to NO<SUB>2</SUB> gas under both a bending strain (r = 3 mm) and a large tensile strain up to 60%. The response of about −15% is measured at a 50 ppm of NO<SUB>2</SUB> under a 60% strain. Furthermore, reducing gases like acetone and ethanol can also be detected under the large strains. The results of this study offer a new insight into realization of highly stretchable and easy-to-fabricate gas sensors.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Highly stretchable gas sensors are fabricated by the dip-coating method. </LI> <LI> The electrical properties of the sensors can be easily tuned. </LI> <LI> The sensors can detect an oxidizing gas, NO<SUB>2</SUB>, and reducing gases, acetone and ethanol. </LI> <LI> The stretchable gas sensors work stably even under large strains up to 60%. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
Overview of Environmental Issues in China
Luan, Sheng Ji 대한원격탐사학회 2000 International Symposium on Remote Sensing Vol.16 No.1
This report assesses several environmental problems in which environmental pollution plays a major role in China. The focus of this report is on the delivery of information on pressures, state and impact. Furthermore the trends in the main driving forces are described influencing the state of the environment. For each problem, the DPSIR approach is followed in this report.
Gene Expression Profiling in the Pituitary Gland of Laying Period and Ceased Period Huoyan Geese

Huoyan goose is a Chinese local breed famous for its higher laying performance, but the problems of variety degeneration have emerged recently, especially a decrease in the number of eggs laid. In order to better understand the molecular mechanism that underlies egg laying in Huoyan geese, gene profiles in the pituitary gland of Huoyan geese taken during the laying period and ceased period were investigated using the suppression subtractive hybridization (SSH) method. Total RNA was extracted from pituitary glands of ceased period and laying period geese. The cDNA in the pituitary glands of ceased geese was subtracted from the cDNA in the pituitary glands of laying geese (forward subtraction); the reverse subtraction was also performed. After sequencing and annotation, a total of 30 and 24 up and down-regulated genes were obtained from the forward and reverse SSH libraries, respectively. These genes mostly related to biosynthetic process, cellular nitrogen compound metabolic process, transport, cell differentiation, cellular protein modification process, signal transduction, small molecule metabolic process. Furthermore, eleven genes were selected for further analyses by quantitative real-time PCR (qRT-PCR). The qRT-PCR results for the most part were consistent with the SSH results. Among these genes, Synaptotagmin-1 (SYT1) and Stathmin-2 (STMN2) were substantially over-expressed in laying period compared to ceased period. These results could serve as an important reference for elucidating the molecular mechanism of higher laying performance in Huoyan geese.
