针对光伏电池单二极管参数的提取中，蛇优化算法收敛速度慢、收敛精度低、易于陷入局部最优的问题，提出一种混沌自适应权重改进蛇优化算法。混沌的初始化以及自适应权重的设置可动态地改善算法在寻找食物、战斗、交配中的比例。通过对比不同光强和温度下理论与实验伏安数据，验证了改进算法的有效性。结果表明，相比于蛇优化算法，改进算法在收敛速度方面提高约219.7%，精度提高约58.40%，稳定性提高约49.57%。且发现光强对光生电流的影响比温度大，温度对反向饱和电流、串联电阻、并联电阻、理想因子的影响比光强大。

As a semiconductor material with a 2 D-laminate structure, g-C_(3)N_(4)(bandwidth 2.7 e V) has a similar structure and excellent performance to graphene. However, high surface energy and photogenerated e–h recombination of g-C_(3)N_(4)seriously hinder its application in the field of marine anticorrosion and *** solve these problems, we synthesized the g-C_(3)N_(4)nanosheets decorated with Zn O nanoring via chemical etching technology. Whether the NR Zn O-CNNs have surface protection performance among the pure EP on the corrosion protection for metal substrate were investigated. The antifouling properties NR Zn OCNNs hybrid were also estimated through photocatalytic bacterial and algae resistance tests. Combined with the electrochemical results, it was found that the impedance modulus of NR Zn O-CNNs/EP within 45 days showed two orders of magnitude higher than that of pure EP in the 3.5 wt% Na Cl solution. Besides, Local electrochemical impedance spectroscopy(LEIS) further explored the anticorrosion behavior of NR Zn O-CNNs/EP coating, which indicated that the NR Zn O-CNNs/EP coating with a scratch maintained an excellent corrosion resistance between 0–24 h. Under the visible light conditions, the lifetime of photogenerated e–h was prolonged due to the formation of NR Zn O-CNNs heterojunction structure, it was observed that the antibacterial rate against Bacillus subtilis reached 100% within 8 h. An Antialgae test was performed on chlorella seawater solution, which indicated that 5 mg/m L of NR Zn O-CNNs hybrid could make chlorella sharply reduce within 4 days. Simultaneously, the corrosion protection and photocatalytic antifouling mechanisms of NR Zn O-CNNs were proposed, thus it provided a broader platform for the design of versatile marine protection materials.

There are favorable exploration prospects in igneous rock reservoirs. However, problems of borehole instability occur frequently during drilling igneous formations, which is a serious impediment to oil and gas exploration and production. The lack of systematic understanding of the inherent instability mechanisms is an important problem. A series of experiments were conducted on several igneous rock samples taken from the sloughing formations in the Tuha area in an attempt to reveal the inherent mechanisms of wellbore instability when drilling in fractured igneous rocks. Research methods involved slurry chemistry, analysis of micro-geological features （Micro-CT imaging, SEM）, and rock mechanics testing. The experimental results indicated that clay minerals were widely distributed in the intergranular space of the diagenetic minerals, crystal defects, and microcracks. Drilling fluid filtrate would invade the rock along the microcracks. Tile invasion amount gradually increased over time, which constantly intensified the hydration and swelling of clay minerals, leading to changes in the microscopic structure of igneous rocks. Primary and secondary microcracks can propagate and merge into single cracks and thus reducing rock cohesion and the binding force along cleavage planes. Based on this result the authors propose that a key towards solving wellbore instability in igneous formations is that specific micro-geological characteristics of the igneous rocks should be taken into consideration in the design of antisloughing drilling muds.

Traditional data driven fault detection methods assume that the process operates in a single mode so that they cannot perform well in processes with multiple operating modes. To monitor multimode processes effectively,this paper proposes a novel process monitoring scheme based on orthogonal nonnegative matrix factorization(ONMF) and hidden Markov model(HMM). The new clustering technique ONMF is employed to separate data from different process modes. The multiple HMMs for various operating modes lead to higher modeling *** proposed approach does not presume the distribution of data in each mode because the process uncertainty and dynamics can be well interpreted through the hidden Markov estimation. The HMM-based monitoring indication named negative log likelihood probability is utilized for fault detection. In order to assess the proposed monitoring strategy, a numerical example and the Tennessee Eastman process are used. The results demonstrate that this method provides efficient fault detection performance.

卷积神经网络作为深度学习的典型代表,是计算机视觉等任务中最常用的神经网络,然而,卷积运算通常占整个卷积神经网络运行时的90%以上,成为卷积神经网络的性能瓶颈。此外,由于当下硬件的复杂性及工作负载的多样性,之前工作中的一些特定优化往往缺乏性能可移植性。对此,作者提出BlazerML,一个基于张量虚拟机(TVM)模板代码自动生成的开源卷积计算库,可为任何输入形状自动生成高性能的卷积实现。BlazerML是基于Winograd算法实现的,因为该算法是快速卷积算法中性能最高的算法。实验结果表明:BlazerML显著优于当下最先进的开源库。在x86 CPU上运行常见的深度学习网络前向推理分别比OnnxRuntime、MNN和TVM社区版本快1.18~2.47倍、1.18~2.27倍和1.01~1.66倍。在ARMCPU上运行常见深度学习网络的单层推理分别比ACL和FastConv快1.26~6.11倍、1.04~4.28倍。

Systemic lupus erythematosus （SLE） is a complex autoimmune disease characterized by the production of autoantibodies to a broad range of self-antigens. Profiling the autoantibody repertoire using array-based technology has emerged as a powerful tool for the identification of biomarkers in SLE and other autoimmune diseases. Proteomic microarray has the capacity to hold large number of self-antigens on a solid surface and serve as a high-throughput screening method for the determination of autoantibody specificities. The autoantigen arrays carrying a wide variety of self-antigens, such as cell nuclear components （nucleic acids and associated proteins）, cytoplas- mic proteins, phospholipid proteins, cell matrix proteins, mucosal/secreted proteins, glomeruli, and other tissue-specific proteins, have been used for screening of autoantibody specificities associated with different manifestations of SLE. Arrays containing synthetic peptides and molecular modified proteins are also being utilized for identification of autoantibodies targeting to special antigenic epi- topes. Different isotypes of autoantibodies, including IgG, IgM, IgA, and IgE, as well as other Ig subtypes, can be detected simultaneously with multi-color labeled secondary antibodies. Serum and plasma are the most common biologic materials for autoantibody detection, but other body fluids such as cerebrospinal fluid, synovial fluid, and saliva can also be a source of autoantibody detection.
