Purpose: Consumption patterns are shifting with digital virtualization to form new marketing models, and App icon design is the key to differentiation in the digital marketing process for companies. The aim of this study is to investigate the effect of App authenticity and App authority on App attractiveness and App loyalty. In addition, The moderating effects of App features and nationality differences on app authenticity, App authority, and App loyalty in a relationship mediated by App attractiveness are also explored. The study is dedicated to providing useful information for companies to understand the Korean market and Chinese market customers from the perspective of App digital marketing and to develop strategies to attract more customers. Research design, data, and methodology: In order to achieve the research purpose, Using App icon features as the entry point, App authenticity and App authority as independent variables, and introducing App attractiveness as a mediating variable, this study verified the impact on the dependent variable App loyalty using data from a survey of 334 Korean and Chinese consumers. Results: The empirical results are summarized as follows. Firstly, App Authenticity has a positive (+) impact on App attractiveness. Secondly, App Authority has a positive (+) effect on App Attractiveness and App Loyalty. Third, App attractiveness has a positive (+) effect on App loyalty. Fourthly, all relationships between App attractiveness App authenticity, and App loyalty are partial mediating effect. Fifth, only a partial mediating effect of Graphic-Korea exists between App attractiveness in terms of App authority and App loyalty. Sixth, only the hypothesis of a moderating effect between App authority * App features, and App authenticity * nationality is valid. Implications: When designing applications, companies should express the concept of the brand with maximum accuracy, communicate the values of the company and maintain the inherent symbolic image of the brand. Respect the consumer, respect the cultural differences of different countries and approach them with Authenticity. The results of the study help companies to design App icons more precisely to help improve App attractiveness, and App loyalty and this study provides a theoretical basis for the development of digital marketing for brands.
PIAS: Practical Information-Agnostic Flow Scheduling for Commodity Data Centers
Bai, Wei,Chen, Li,Chen, Kai,Han, Dongsu,Tian, Chen,Wang, Hao IEEE 2017 IEEE/ACM transactions on networking Vol.25 No.4
<P>Many existing data center network (DCN) flow scheduling schemes, that minimize flow completion times (FCT) assume prior knowledge of flows and custom switch functions, making them superior in performance but hard to implement in practice. By contrast, we seek to minimize FCT with no prior knowledge and existing commodity switch hardware. To this end, we present PIAS, a DCN flow scheduling mechanism that aims to minimize FCT by mimicking shortest job first (SJF) on the premise that flow size is not known a priori. At its heart, PIAS leverages multiple priority queues available in existing commodity switches to implement a multiple level feedback queue, in which a PIAS flow is gradually demoted from higher-priority queues to lower-priority queues based on the number of bytes it has sent. As a result, short flows are likely to be finished in the first few high-priority queues and thus be prioritized over long flows in general, which enables PIAS to emulate SJF without knowing flow sizes beforehand. We have implemented a PIAS prototype and evaluated PIAS through both testbed experiments and ns-2 simulations. We show that PIAS is readily deployable with commodity switches and backward compatible with legacy TCP/IP stacks. Our evaluation results show that PIAS significantly outperforms existing information-agnostic schemes, for example, it reduces FCT by up to 50% compared to DCTCP [11] and L2DCT [32]; and it only has a 1.1% performance gap to an ideal information-aware scheme, pFabric [13], for short flows under a production DCN workload.</P>

Background: Previous studies accessing the association of CYP2C19 with outcomes of patients using tamoxifen for breast cancer have yielded conflicting results. The aim of this meta-analysis is to obtain a more precise estimate of effects of CYP2C19 polymorphisms and to clarify their effects on survival of the breast cancer patients using tamoxifen. Materials and Methods: A systematic search of PubMed and Embase was performed, comparing patients with or without $CYP2C19^*2$ and $CYP2C19^*17$, relevant articles searched for. The following outcomes were included from the eligible studies: disease-free survival (DFS) and overall survival (OS), expressed by hazard ratios (HR) with corresponding 95% confidence interval (CI). Subgroup analysis by genotypes was also performed. Pooled estimates were calculated using random-effect model in accordance to the heterogeneity. Results: Six studies met the inclusion criteria. The integrated OR on the association between CYP2C19 and DFS, calculated by the random-effect model, was 0.54 (95%CI=0.34-0.84, p=0.013). Subgroup analysis showed that both $CYP2C19^*2$ and $CYP2C19^*17$ were associated with increased survival. The pooled results of two studies for OS were OR=0.46 (95%CI=0.21-1.01, p=0.233). Conclusions: This meta-analysis suggests that the $CYP2C19^*2$ and $CYP2C19^*17$ genotypes are associated with increased survival in breast cancer patients using tamoxifen.

In most industrial environments, the real process data points are usually subject to contamination from a variety of noises. Most of the traditional methods assume that the process noise is Gaussian white noise, which can lead to poor robustness of the model to abnormal data. In this paper, we consider an ARX model with multi-Gaussian white noises, assuming that the collected data is affected by different noise models and switching of noise model follows Markov chain probability. The parameters of the model are estimated by Expectation-Maximization (EM) algorithm. A numerical example and a continuous stirred tank reactor are employed to verify the effectiveness of the proposed algorithm.

Ru Bai,Ju Zhang,Changwang Yan,Shuguang Liu,Xiaoxiao Wang,Zhijie Yang,Hao Jing 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.6
Using pulverized calcium silicate slag (CSS) to replace part of Portland cement (PC) as composite cementitious material is the most energy-saving and clean treatment method. The main objective of this study was to investigate the delayed strength development of the CSS-PC composite cementitious. The compressive strength of the composite cementitious with 10% to 40% CSS was tested, the delayed strength was calculated, and the delayed age was analyzed. Results showed that the delayed strength and delayed age increased with the increase in the substitution rate of CSS, which was determined by the ratio of C2S and C3S. Moreover, a compressive strength prediction model of CSS–PC composite cementitious was established based on the “core-shell” hydration model. The calculated value was compared with the specification value of each country to analyze whether the compressive strength of CSS-PC composite cementitious meets the engineering requirements.
Novel Robust High Dynamic Range Image Watermarking Algorithm Against Tone Mapping
( Yongqiang Bai ),( Gangyi Jiang ),( Hao Jiang ),( Mei Yu ),( Fen Chen ),( Zhongjie Zhu ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.9
High dynamic range (HDR) images are becoming pervasive due to capturing or rendering of a wider range of luminance, but their special display equipment is difficult to be popularized because of high cost and technological problem. Thus, HDR images must be adapted to the conventional display devices by applying tone mapping (TM) operation, which puts forward higher requirements for intellectual property protection of HDR images. As the robustness presents regional diversity in the low dynamic range (LDR) watermarked image after TM, which is different from the traditional watermarking technologies, a concept of watermarking activity is defined and used to distinguish the essential distinction of watermarking between LDR image and HDR image in this paper. Then, a novel robust HDR image watermarking algorithm is proposed against TM operations. Firstly, based on the hybrid processing of redundant discrete wavelet transform and singular value decomposition, the watermark is embedded by modifying the structure information of the HDR image. Distinguished from LDR image watermarking, the high embedding strength can cause more obvious distortion in the high brightness regions of HDR image than the low brightness regions. Thus, a perceptual brightness mask with low complexity is designed to improve the imperceptibility further. Experimental results show that the proposed algorithm is robust to the existing TM operations, with taking into account the imperceptibility and embedded capacity, which is superior to the current state-of-art HDR image watermarking algorithms.
