Accelerating the Sweep3D for a Graphic Processor Unit

Gong, Chunye,Liu, Jie,Chen, Haitao,Xie, Jing,Gong, Zhenghu Korea Information Processing Society 2011 Journal of information processing systems Vol.7 No.1

As a powerful and flexible processor, the Graphic Processing Unit (GPU) can offer a great faculty in solving many high-performance computing applications. Sweep3D, which simulates a single group time-independent discrete ordinates (Sn) neutron transport deterministically on 3D Cartesian geometry space, represents the key part of a real ASCI application. The wavefront process for parallel computation in Sweep3D limits the concurrent threads on the GPU. In this paper, we present multi-dimensional optimization methods for Sweep3D, which can be efficiently implemented on the finegrained parallel architecture of the GPU. Our results show that the overall performance of Sweep3D on the CPU-GPU hybrid platform can be improved up to 4.38 times as compared to the CPU-based implementation.

Applying the IS Success Model and Service Quality on e-Banking in China

꽁징(Gong, Jing),유인선(Yoo, In-Seon),이은곤(Lee, Un-Kon) 한국상품학회 2014 商品學硏究 Vol.32 No.3

연구목적: 최근 은행들은 e-뱅킹 시스템을 도입함으로써 경쟁자에 비해 자사의 서비스를 차별화하고 고객의 온라인 경험을 증진시키고자 시도하고 있으나, e-뱅킹 시스템을 어떻게 설계하여야 할지 가이드라인 없이 진행되고 있는 상황이다. 선행연구들은 정보시스템의 성공적 도입을 위해서는 3Q(시스템 품질, 정보 품질 및 서비스 품질)가 필수적으로 고려되어야 한다고 주장하고 있다. 그러나 3Q의 세부 구성 요소들이 정보시스템 성과에 어떤 영향을 미치는지, 그리고 e-뱅킹 시스템의 상황에서 이 관계를 실증적으로 분석하지 못하고 있다. 본 연구에서는 Delone & Mclean의 정보시스템 성과 모델을 중심으로 선행연구를 종합하여 3Q의 세부 구성 요소들을 조작화(operationalization)하고, 이를 중국 동북지역의 e-뱅킹 시스템 사례를 기반으로 검증하고자 하였다. 연구 설계 및 방법론: 총 350개의 자발적 참여자를 모집하였으며, 306개의 유효한 데이터를 설문지법을 활용하여 수집하였으며 PLS 알고리즘을 이용하여 분석을 진행하였다. 분석 및 연구 결과: 분석결과, 주로 거래 성공에 관한 품질 변수(보안, 정확성, 공감)들은 e-서비스 만족도와 e-신뢰 모두를 유의하게 증가시키는 것으로 조사되었으나, 보다 거래를 편리하게 이용하기 위한 품질 변수(편리성, 이용의 편이성, 응답가능성)은 e-서비스만족도만을 증가시키는 것으로 조사되었다. 동시에 유희적(hedonic) 품질 변수(심미적 디자인, 콘텐츠의 충실성)은 e-서비스만족도와 e-신뢰에 유의한 영향을 미치지 못하는 것으로 조사되었다. 선행 연구의 흐름과 같이 서비스만족도와 신뢰는 충성도에 유의한 영향을 미치는 것으로 나타났다. 시사점 및 연구의 한계점: e-뱅킹 서비스 이용자의 경우 거래의 성공과 편이성에 관한 품질 변수가 유희적 변수들에 비해 더욱 중요할 수 있다. 은행 경영진들은 거래의 성공과 편이성에 관한 품질 변수에 역점을 두어 e-뱅킹 시스템을 개선할 수 있을 것이라 판단된다. 본 연구는 중국 동부 지역의 대학생을 대상으로 자료를 수집한 바, 여타 온라인 서비스에 대한 비교 등 추가적인 연구가 필요할 것으로 판단된다. 향후 연구방향: e-뱅킹 서비스의 유희적 품질에 대한 추가 연구가 필요하다. 공헌점: 본 연구는 3Q라는 세 가지 차원의 e-서비스 품질 요소들을 종합하고, 이 요소들이 e-뱅킹 소비자의 경험에 어떠한 영향을 미치는 지 실증적으로 검증한 연구이다. Purpose: Banks try to adopt e-banking systems in order to differentiate their own services with competitors as well as, enhance customer online experiential value; however, these practices had been performed with minimal guidelines. Prior studies have suggested that 3Q (system quality, information quality, and service quality) could be essential in IS service success. Yet, only a few studies had investigated the detail components of the 3Q variables and empirically validated the effect of these components in the e-banking context. In this study, we tried to operationalize the detailed components of 3Q in e-banking adoption in China, based on DeLone and McLean's IS success model. Design/methodology/approach: Among 350 voluntary e-banking service users, 306 valid data had been collected and analyzed using PLS-SEM algorism. Results/findings: Transaction success factors (security, accuracy, and empathy) could significantly affect both e-satisfaction and e-trust; transaction convenience relationship (convenience, ease of use, and responsiveness) could significantly affect only e-satisfaction; transaction stability (fulfillment, timeliness, and assurance) could significantly affect only e-trust; however, hedonic elements (aesthetics and content) could not significantly affect both e-satisfaction and e-trust. Following the previous studies, satisfaction and trust could significantly affect loyalty. Research implications/limitations: Utilitarian value is more important than hedonic value for e-banking service users. Hence, bank managers should pay more attention to the utilitarian value related to quality components. However the model is tested in e-banking context and the fitness to other online service is not decided yet. Future work/research: Further study should be applied to the antecedents and consequences of hedonic value of e-service. Originality/value: This study combined 3Q with e-service quality dimension, and validated the effect between the detailed components of 3Q and customer experience in the e-banking context. Moreover, the hedonic value of e-banking service was discussed.

LY294002 Induces G0/G1 Cell Cycle Arrest and Apoptosis of Cancer Stem-like Cells from Human Osteosarcoma Via Down-regulation of PI3K Activity

Gong, Chen,Liao, Hui,Wang, Jiang,Lin, Yang,Qi, Jun,Qin, Liang,Tian, Lin-Qiang,Guo, Feng-Jing Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7

Osteosarcoma, the most common primary mesenchymal malignant tumor, usually has bad prognosis in man, with cancer stem-like cells (CSCs) considered to play a critical role in tumorigenesis and drug-resistance. It is known that phosphatidylinositol 3-kinase (PI3K) is involved in regulation of tumor cell fates, such as proliferation, cell cycling, survival and apoptosis. Whether and how PI3K and inhibitors might cooperate in human osteosarcoma CSCs is still unknown. We therefore evaluated the effects of LY294002, a PI3K inhibitor, on the cell cycle and apoptosis of osteosarcoma CSCs in vitro. LY294002 prevented phosphorylation of protein kinase B (PKB/Akt) by inhibition of PI3K phosphorylation activity, thereby inducing G0/G1 cell cycle arrest and apoptosis in osteosarcoma CSCs. Further studies also demonstrated that apoptosis induction by LY294002 is accompanied by activation of caspase-9, caspase-3 and PARP, which are involved in the mitochondrial apoptosis pathway. Therefore, our results indicate PI3K inhibitors may represent a potential strategy for managing human osteosarcoma via affecting CSCs.

SEUSS Integrates Gibberellin Signaling with Transcriptional Inputs from the SHR-SCR-SCL3 Module to Regulate Middle Cortex Formation in the Arabidopsis Root

Gong, Xue,Flores-Vergara, Miguel A.,Hong, Jing Han,Chu, Huangwei,Lim, Jun,Franks, Robert G.,Liu, Zhongchi,Xu, Jian American Society of Plant Biologists 2016 Plant Physiology Vol.170 No.3

<P>A decade of studies on middle cortex (MC) formation in the root endodermis of Arabidopsis (Arabidopsis thaliana) have revealed a complex regulatory network that is orchestrated by several GRAS family transcription factors, including SHORT-ROOT (SHR), SCARECROW (SCR), and SCARECROW-LIKE3 (SCL3). However, how their functions are regulated remains obscure. Here we show that mutations in the SEUSS (SEU) gene led to a higher frequency of MC formation. seu mutants had strongly reduced expression of SHR, SCR, and SCL3, suggesting that SEU positively regulates these genes. Our results further indicate that SEU physically associates with upstream regulatory sequences of SHR, SCR, and SCL3; and that SEU has distinct genetic interactions with these genes in the control of MC formation, with SCL3 being epistatic to SEU. Similar to SCL3, SEU was repressed by the phytohormone GA and induced by the GA biosynthesis inhibitor paclobutrazol, suggesting that SEU acts downstream of GA signaling to regulate MC formation. Consistently, we found that SEU mediates the regulation of SCL3 by GA signaling. Together, our study identifies SEU as a new critical player that integrates GA signaling with transcriptional inputs from the SHR-SCR-SCL3 module to regulate MC formation in the Arabidopsis root.</P>
