A robust TV logo detection method based on the modified single shot multibox detector (SSD) is presented. Unlike most other existing methods which can only detect the TV logo from video frames, the proposed method can also detect the TV logo from photo pictures taken by smartphones or other smart terminals. Firstly, using a simple and effective way of collecting and labelling TV logo, a large-scale TV logo dataset used to train the detection model is built. Then, parameters and loss function of SSD are modified to make it more suitable for the task of TV logo detection. Moreover, a soft-NMS algorithm is introduced to remove the redundant overlapping boxes and obtain the final output box. And also an approach for hard example mining is designed to improve the detection accuracy. Finally, extensive comparison experiments are carried out which take into consideration different image resolutions, logo positions and environmental factors existing in real-world applications. Experimental results demonstrate that the proposed method achieve superior performances in robustness compared to other state-of-the-art methods.

As semiconductor manufacturers march to thedrum beat of Moore's Law there is very little roomfor yield maverieks, especially those that can beprevented. Critical process errors are costly andphotolithography is one of the few processes insemiconductor manufacturing where there is anopportunity to correct errors. Small changes inphotoresist-dispensed volume may have severeimpact on film thickness uniformity and can ulti-mately affect patterning It is important to monitorphoto dispense conditions to detect real-timeevents that may have a direct negative impact onprocess yield and be able to react to these eventsas quickly as *** paper presents an evaluation of the IntelliGen Mini, a photoresist dispense system manufacturedby Entegris, inc. This system utilizes advancedequipment control software, known as dispenseconfirmation, to detect variations in photo dis-pense. These variations, caused by bubbles inthe dispense line, valve errors and accidentally-changed chemistries can all create maverick yieldevents that can go undetected until metrology,defeet inspection or wafer final testThe ability of an advanced dispense system todetect events and create alerts is a very powerfultool, but it can be most effective when that infor-mation is collected and analyzed by an automatedsystem. In a modern fabricator this is most likely astatistical process control chart that is monitoringa track's progress and is ready to stop the trackwhen a maverick event occurs or alert personnelto trends they may not otherwise catch with otherinline ntetrology data.

Purpose： The purpose of this study is to modernize previous work on science overlay maps by updating the underlying citation matrix, generating new clusters of scientific disciplines, enhancing visualizations, and providing more accessible means for analysts to generate their own maps Design/methodology/approach： We use the combined set of 2015 Journal Citation Reports for the Science Citation Index （n of journals = 8,778） and the Social Sciences Citation Index （n = 3,212） for a total of 11,365 journals. The set of Web of Science Categories in the Science Citation Index and the Social Sciences Citation Index inc.eased from 224 in 2010 to 227 in 2015. Using dedicated software, a matrix of 227 × 227 cells is generated on the basis of whole-number citation counting. We normalize this matrix using the cosine function. We first develop the citing-side, cosine-normalized map using 2015 data and VOSviewer visualization with default parameter values. A routine for making overlays on the basis of the map （＂wc ***＂） is available at http：//***/wc 15/***. Findings： Findings appear in the form of visuals throughout the manuscript. In Figures 1 9 we provide basemaps of science and science overlay maps for a number of companies, universities, and technologies. Research limitations： As Web of Science Categories change and/or are updated so is the need to update the routine we provide. Also, to apply the routine we provide users need access to the Web of Science. Practical implications： Visualization of science overlay maps is now more accurate and true to the 2015 Journal Citation Reports than was the case with the previous version of the routine advanced in our ***/value： The routine we advance allows users to visualize science overlay maps in VOSviewer using data from more recent Journal Citation Reports.

非同步通讯模式的统计模型为在二维网络上实现多模式通讯奠定了理论基础。在此基础上,一些应用的尝试也逐步展开。到目前为止,这些应用还都局限在人工产生通讯模式的范围内。提出了通讯过程决策树的严格的形式定义和依时间梢等概率树的递推性定义,以及诸如:全对称、完全、均匀、半均匀、殆半均匀等概念,并讨论了梢的概率分布,及其与各时刻各节点处概率分布的关系,证明了两个定理。这些概念和定义将为今后自动生成通讯模式建立一个理论框架。

作者：胡利云张浩亮贾芳陶向阳 Center for Quantum Science and Technology College of Physics and Communication Electronics Jiangxi Normal University

In this paper, we introduce a new way to obtain the Q-P （P-Q） ordering of quantum mechanical operators, i.e., from the classical correspondence of Q-P （P-Q） ordered operators by replacing q and p with coordinate and momentum operators, respectively. Some operator identities are derived concisely. As for its applications, the single （two-） mode squeezed operators and Fresnel operator are examined. It is shown that the classical correspondence of Fresnel operator’s Q-P （P-Q） ordering is just the integration kernel of Fresnel transformation. In addition, a new photo-counting formula is constructed by the Q-P ordering of operators.
