摘要：We consider the problem of learning a representation of both spatial relations and dependencies between objects for indoor scene *** propose a novel knowledge graph framework based on the entity-relation model for representation of facts in indoor scene design, and further develop a weaklysupervised algorithm for extracting the knowledge graph representation from a small dataset using both structure and parameter learning. The proposed framework is flexible, transferable, and readable. We present a variety of computer-aided indoor scene design applications using this representation, to show the usefulness and robustness of the proposed framework.

摘要：Bone tissue engineering (BTE) is a rapidly developing strategy for repairing critical-sized bone defects to address the unmet need for bone augmentation and skeletal repair. Effective therapies for bone regeneration primarily require the coordinated combination of innovative scaffolds, seed cells, and biological factors. However, current techniques in bone tissue engineering have not yet reached valid translation into clinical applications because of several limitations, such as weaker osteogenic differentiation, inadequate vascularization of scaffolds, and inefficient growth factor delivery. Therefore, further standardized protocols and innovative measures are required to overcome these shortcomings and facilitate the clinical application of these techniques to enhance bone regeneration. Given the deficiency of comprehensive studies in the development in BTE, our review systematically introduces the new types of biomimetic and bifunctional scaffolds. We describe the cell sources, biology of seed cells, growth factors, vascular development, and the interactions of relevant molecules. Furthermore, we discuss the challenges and perspectives that may propel the direction of future clinical delivery in bone regeneration.

摘要：Novel construction of a resonant-cavity-enhanced photodetector(RCE-PD) with monolithic high-contrast grating(HCG)is proposed to overcome the difficulty of fabricating a high reflective mirror of RCE-PD at 1 550 nm. In this structure,HCG serves as the top mirror of the RCE-PD, whereas InGaAs serves as a sacrificial layer to achieve monolithic *** the bandwidth optimization, the ratio of the thickness of the total intrinsic region and the absorption layer is introduced to realize the simultaneous optimization of the thickness of spacing layers and absorption layer. After structural optimization, the quantum efficiency of the device with diameter of 20 μm is 82% at 1 550 nm, and the 3-dB bandwidth is 34 GHz at a bias of 3 V.

摘要：This paper studies the problem of suboptimal state-feedback H-two/H-infinity control of stochastic systems with spectrum constraint. Concretely speaking, a mixed suboptimal H-two/H-infinity controller synthesis together with placing the spectrum into a strip region is considered, which is achieved via solving a convex optimization problem.

摘要：A Weighted Essentially Non-Oscillatory scheme(WENO) is a solution to hyperbolic conservation laws,suitable for solving high-density fluid interface instability with strong intermittency. These problems have a large and complex flow structure. To fully utilize the computing power of High Performance Computing(HPC) systems, it is necessary to develop specific methodologies to optimize the performance of applications based on the particular system’s architecture. The Sunway TaihuLight supercomputer is currently ranked as the fastest supercomputer in the world. This article presents a heterogeneous parallel algorithm design and performance optimization of a high-order WENO on Sunway TaihuLight. We analyzed characteristics of kernel functions, and proposed an appropriate heterogeneous parallel model. We also figured out the best division strategy for computing tasks,and implemented the parallel algorithm on Sunway TaihuLight. By using access optimization, data dependency elimination, and vectorization optimization, our parallel algorithm can achieve up to 172× speedup on one single node, and additional 58× speedup on 64 nodes, with nearly linear scalability.

摘要：This paper investigates a distributed recursive projection identification problem with binaryvalued observations built on a sensor network,where each sensor in the sensor network measures partial information of the unknown parameter only,but each sensor is allowed to communicate with its neighbors.A distributed recursive projection algorithm is proposed based on a specific projection operator and a diffusion *** authors establish the upper bound of the accumulated regrets of the adaptive predictor without any requirement of excitation ***,the convergence of the algorithm is given under the bounded cooperative excitation condition,which is more general than the previously imposed independence or persistent excitations on the system regressors and maybe the weakest one under binary observations.A numerical example is supplied to demonstrate the theoretical results and the cooperative effect of the sensors,which shows that the whole network can still fulfill the estimation task through exchanging information between sensors even if any individual sensor cannot.

摘要：电容式压力传感器是一种将压力转换成电信号的高效可靠的传感器,具有广泛的用途.柔性电容式压力传感器的结构可能会发生较大的变形,大变形下的灵敏度和线性度是柔性压力传感器的主要性能指标,无法用传统小变形理论进行分析。因此,建立能够准确预测外部压力下柔性压力传感器的变形和力-电耦合性能的理论模型对传感器的定量设计至关重要.在本文中,我们提出了一个力-电耦合理论模型,分析了柔性电极在弯曲大变形下的电容变化.该理论被用来预测柔性菱形电容式传感器的变形和电容变化关系,并通过数值模拟和实验进行了验证。该力-电耦合理论可用于对具有对称柔性/弧形电极的悬臂式电容器在对称载荷作用下的力-电性能进行分析和设计,并可退化为文献中的小变形理论.准确的理论分析模型可以促进电容式压力传感器和其他类似结构的研究和设计。

摘要：AIM： To present the rationale, design, methodology, and the baseline data of the beijing Desheng Diabetic Eye Study（BDDES）, and to determine the prevalence of diabetic retinopathy（DR） and possible risk factors in patients with type 2 diabetes mellitus（T2DM） in an urban community of beijing, ***： Community-based prospective cohort study of persons diagnosed with T2DM aged 30 y or older. The main variables of interest are the presence and progression of DR as determined by the standardized ETDRS grading of seven fields fundus photographs. The presence and severity of DR were analyzed for possible correlations to non-genetic and genetic ***： A total of 1438 participants with data available for analysis, the prevalence of any DR was 35.4%. The prevalence of mild non-proliferative diabetic retinopathy（NPDR）, moderate NPDR, severe NPDR, and proliferative diabetic retinopathy was 27.7%, 2.6%, 0.5% and 4.5%, respectively. By multiple logistic regression analysis, risk factors for the presence of any DR included male（P=0.031）, lower income level（P=0.011）, lower education background（P=0.022）, longer duration of diabetes（P=0.001）, younger age at diabetic onset（P=0.001）, higher systolic blood pressure（P=0.007）, higher glycosylated hemoglobin A1 c levels（P=0.001）, high albuminuria（P=0.03）, and use of insulin（P〈0.001）. For vision-threatening DR, four factors were significant： younger age at diabetic onset（P〈0.001）,higher systolic blood pressure（P=0.042）, high albuminuria（P〈0.001）, and use of insulin（P〈0.001）. CONCLUSION： The BDDES is the first large-scale ongoing cohort study of a Chinese urban population of persons with type 2 diabetes. Using standardized grading system comparable to large cohort studies from western populations, our baseline data shows that the prevalence of DR and major risk factors in this Chinese ethnic population are comparable to that found in the western population studies.
