| 2 | THE CONVERGENCE OF BROYDEN ALGORITHMS FOR LC GRADIENT FUNCTION显示文摘In this paper, we discuss the convergence of Broyden algorithms for the functions which are non-twice differentiable, but have LC gradient. We prove that the rate of convergence of the algorithms is linear for uniformly convex functions. We also demonstrate that under some mild conditions the algorithms are superlinsarly convergent. | 濮定国 | 2000 | Acta Mathematicae Applicatae Sinica2000，16，3： | 1 |
| 3 | VIDEO CODING SCHEME FOR ATM NETWORKS显示文摘A new variable bit rate layered coding scheme based on subband coding is given in this paper. It can make full use of the merits of ATM transmission, as well as compensation for the quality degradation caused by cell loss, which is an inherent problem of ATM networks, and thus a stable, high quality video transmission is achieved. This paper presents the coding scheme, cell construction and simulation results. | 陈霈 贾文辉 沈兰荪 | 1995 | Journal of Electronics(China)1995，12，3： | 1 |

| 5 | Exponential inequalities for associated random variables and strong laws of large numbers显示文摘Some exponential inequalities for partial sums of associated random variables are established. These inequalities improve the corresponding results obtained by Ioannides and Roussas (1999), and Oliveira (2005). As application, some strong laws of large numbers are given. For the case of geometrically decreasing covariances, we obtain the rate of convergence n-1/2(log log n)1/2(logn) which is close to the optimal achievable convergence rate for independent random variables under an iterated logarithm, while Ioannides and Roussas (1999), and Oliveira (2005) only got n-1/3(logn)2/3 and n-1/3(logn)5/3, separately. | Shan-chao YANG & Min CHEN Deptartment of Mathematics, Guangxi Normal University, Guilin 541004, China Academy of Mathematics and Systems Science, Chinese Academy of Sciences, Beijing 100080, China | 2007 | Science China Mathematics2007，50，5： | 1 |

| 7 | A Network Calculus Approach for the Analysis of Packet-switching Networks显示文摘Network calculus is an evolving new methodology for backlog and delay analysis of packet-switching networks. With network calculus we are able to compute tight bounds on delays,backlogs,and effective bandwidths in a lossless setting applicable to packet-switching networks and better understand some physical properties of networks. In this paper,the basic network calculus concepts of arrival curves and service curves are introduced.Then we provide the approach for modeling leaky-bucket,generic cell rate algorithm(GCRA),constant bit rate(CBR)flow, variable bit rate(VBR) flow with arrival curve.It is shown that all rate-based packet schedulers can be by a simple rate latency service curve.And by applying these fundamental rules of network calculus,bounds on delay, buffer,effective bandwidth for leaky bucket,GCRA,CBR and VBR can be derived and some practical examples are given.Finally,we compare all the results obtained and conclude this paper. | Li, Minghui Tan, Xianhai | 2007 | China Communications2007，4，2： | 0 |
| 8 | Asymptotic Stability of Memory-Type Euler-Bernoulli Plate with Variable Coefficients and Time Delay显示文摘This paper considers a viscoelastic Euler-Bernoulli plate system with variable coefficients and time-varying delay. By the multiplier method, Riemannian geometry method, and under suitable assumptions on viscoelastic term and time delay, the authors obtain the general stability of the solution for the system which depends on the behavior of the relaxation function. | WANG Peipei HAO Jianghao | 2019 | Journal of Systems Science & Complexity2019，32，5： | 0 |
| 9 | Study on Site-specific Nutrient Management in Cotton Field显示文摘The study on the characteristics of spatial variability of soil nutrients and fertilizer recommendations in cotton field under certain conditions of agricultural management was conducted with GIS and systematic approach for soil nutrient constrains. The results showed that of the spatial variability of soil nutrient was greatly related to the management condition of previous crops. Grid sampling and variable rate application technology (VRAT) were the tools that would hopefully increase fertilizer efficiency. The fertilizers were applied where they were needed and at proper rate. Balance fertilization demonstration showed that fertilizer recommendations according to the available nutrient level in soil could decrease fertilizer cost with 657.4 yuan / ha and increase seed cotton yield by 19.8%. A net profit of the balanced fertilization was 5314.9 yuan / ha higher than that of local fertilization practice. | YANG Li-ping JIANG Cheng JIN Ji-yun ZHANG Feng-ming | 2001 | Agricultural Sciences in China2001，，1： | 0 |
| 10 | Variable selection procedures from multiple testing显示文摘Variable selection has played an important role in statistical learning and scienti?c discoveries during the past ten years, and multiple testing is a fundamental problem in statistical inference and also has wide applications in many scienti?c ?elds. Signi?cant advances have been achieved in both areas. This study attempts to ?nd a connection between the adaptive LASSO(least absolute shrinkage and selection operator) and multiple testing procedures in linear regression models. We also propose procedures based on multiple testing methods to select variables and control the selection error rate, i.e., the false discovery rate. Simulation studies demonstrate that the proposed methods show good performance relative to controlling the selection error rate under a wide range of settings. | Baoxue Zhang Guanghui Cheng Chunming Zhang Shurong Zheng | 2019 | Science China Mathematics2019，62，4： | 0 |
