Abstract： The study on systematic identification of “Sleeping Beauty” (SB) publications and on their awaking mechanisms will promote the strategic preservation of documents in libraries, and provide implications for identifying potential “ahead of time” discoveries or transformative research, and shortening time lag for original research to get recognized. Based on the data analysis and case studies, this paper figured out some key characteristics of SB publications. The content of SB papers tends to be multi-discipline research and most of which tend to be published in prestigious multidisciplinary journals with higher impact and wider scope. One is perhaps more inclined to believe that SB relate to more fundamental and basic, and less to application-oriented work. But a surprising finding is that half of the SBs are application oriented and significantly more cited in patents than ‘normal’ papers, which demonstrated the potential technical and application-research properties of SB. The key publications and pioneering works of the recent Nobel Prize winners for physiology and medicine are delayed-cited rather early-cited in the entire citation life-time of an article. We further suggested several clues for early identifying SB. First, Transformative research tend to be neglected or resisted by the scientific community initially and this neglect or resistance could be regarded as the key clue for the early prediction of SB literature. Publications belonging to so-called transformative research, even when less frequently cited than others, should be given special attention as early as possible, because they may suddenly attract many citations after a period of sleep. One could identify transformative research through some text terms (such as "disagree", "overcome", "break", "dispute"...). In order to discern such potential transformative research, we could observe whether the relevant documents get early citation from patents or not, because many SB documents tend to be technical research in nature and application-oriented. Second, the Bcp index proposed in our foregoing paper is more sensitive in identifying the “lower level SBs”, which refers to the case when the total citations and the maximum annual citations of SBs are not so high in comparison with other typical SBs. This index may be used to identify the papers at the sleeping-awakening interface, which provided new tools for arousing attention of the science community to previously overlooked but important research. We also pondered some policy implications about the associations of SB publications with transformative research, research front and research evaluation.

Abstract：[目的/意义] 通过优化提出一个可精准识别睡美人文献的简易无参数指标。[方法/过程] 借鉴睡美人指数（B指数）基本框架，通过将考察对象“年度被引次数”优化为“年度被引次数累积百分比”，提出Bcp指数，重新定义唤醒时间、睡眠深度和唤醒强度。并通过识别Science和Nature上的睡美人文献进行检验。[结果/结论] Bcp指数继承了B指数对那些非常显著的睡美人文献高度敏感的优点。Bcp指数框架下计算出的唤醒时间更符合实际情况，而B指数框架下的唤醒时间易被延迟估计。Bcp指数考虑了观察期内论文全部的引文曲线，规避了B指数无法反映年度被引次数达到最大值以后的引文曲线的缺点。Bcp指数对论文发表之初被引次数的约束效力显著高于B指数，更符合睡美人文献早期零被引和低被引的特征。Bcp指数对年龄大、总被引次数和年度被引次数相对较低的睡美人文献更敏感，有利于挖掘平常易被忽视的非高被引文献中睡美人文献的存在规律。Bcp指数规避了人为参数主观界定的不足，以及不同学科领域论文被引规模差异对睡美人文献统一定义的干扰。

Abstract： This paper proposes a new method of deriving the launch and landing locations based on the orbital motion characteristics of the missiles and elevation database. In this method, the DEM support is introduced to change the assumption of the earth from the reference ellipsoid to a more real shape. The method to improve the prediction accuracy of the position and time of the launch and landing points is discussed. The results with DEM (Digital Elevation Model) indicate the accuracy can be improved by adding a few elevation iterations on the original method. The higher the elevation of the starting and landing points, the better the result would be.

Abstract： The gaze cues of the eyes of others in the environment is an important social information that can guide the individual's attention and further affect the individual's cognitive processing and memory of the object being looked at. More importantly, gaze clues can also give some new characteristics to the object being looked at, which affects the individual's judgment and attitude towards the value of the object. The gaze cue effect and the gaze liking effect respectively reflect how the gaze cues affect the individual's cognition and attitude, and further draw on the views of the theory of mind and the shared signal theory to explain the impact of the gaze cues on the consumer's cognition and attitude. Among them, the influence of gaze cues on consumer cognition is mainly reflected in three aspects: (1) Guide consumers to pay attention. Gaze cues, as an indicative clue, can effectively guide consumers' attention. When consumers see the gaze direction of others, they tend to follow the gaze of others and look in the same direction or things. (2) Affect the depth of information processing by consumers. The study found that the gaze direction affects consumers' attention to the brand and text information in the advertisement. When the model in the advertisement is looking towards the product, consumers will look at the brand and text information in the advertisement for a longer time. The length of the gaze reflects the depth of the participants’ processing of the advertisement information, the gaze cues affect the depth of consumer information processing. (3) Affect consumers' memory of advertisements and other information. When the model in the advertisement is facing the product, it will enhance the consumer's memory effect of the brand and advertisement content, and the participants scored higher on the implicit test. The influence of gaze cues on consumer attitudes is mainly reflected in three aspects: (1) influence consumers' evaluation of products/advertising (2) influence consumers' willingness to buy. Regarding how different gaze cues affect consumers' product evaluation or purchase intention, the current research conclusions are not uniform, and there should be more research to further explore possible moderating variables in the future. (3) Affect consumers' evaluation or perception of spokespersons/service personnel. When the front desk staff look directly at the customers, the customers have a better impression of the front desk staff, believing that they are more friendly, warmer, and more trustworthy, and therefore have a better evaluation of the service quality. Future research can start from the following aspects: (1) Starting from product-related factors, investigate the moderating effect of product types on the effect of gaze cues. (2) From the consumer's point of view, examine whether different gaze cues will further affect consumers' attitudes or impressions towards models/spokespersons, and even their attitudes towards products when consumers feel different levels of loneliness? (3) From the perspective of consumption scenarios, explore how gaze cues affect consumer perceptions and attitudes in a crowded shopping environment? (4) From the perspective of the initiator of the gaze cues, can the gaze cues of the anthropomorphic image have the same effect as the human gaze cues? What impact will the anthropomorphic gaze cues have on consumers?

Abstract： [Purpose/significance] Based on the author's descriptive evaluation of his research and the critical citations of later researchers, the abstract and citation corpus of the breakthrough research are used to extract the feature words. Feature words can be used to understand the abstract and citation corpus features of the breakthrough research and contribute to the identification of breakthrough research. [Method/process] Key documents selected by Science as "Breakthrough of the Year" and "key publications" of Nobel Prize winners were selected as breakthrough research corpus data. Feature words were extracted by integrating abstracts and citation corpus of the paper. In the feature word extraction, the Stanford CoreNlp tool was used to perform word frequency statistics on the corpus, and the feature words were filtered in combination with expert opinions. Then we used the semantic relationship of medical texts to semantically expand feature words, which were used as the seed words. Finally, the retrieval and recognition effects of the abstract and citation feature words were further compared by the recall rate and the precision rate. [Result/conclusion] In the breakthrough research corpus, we selected 8 feature tokens of abstract corpora and 8 feature tokens of citation corpora. In the retrieval and recognition of feature words, the recall rate of the extended feature words of abstracts and citations is the highest, the precision of citation feature words is the highest. The comprehensive effect of the recall rate and precision of citation expansion feature words are better.

Abstract： Quantification of non-structural carbohydrates (NSC) contents of plants is of great significance to the exploration of its growth and adaptive strategies. However, various pretreating methods often lead to the poor comparability among different results. In this paper, four typical psammophytes on the coast of South China including Casuarina equisetifolia, Spinifex littoreus, Ipomoea pes-caprae and Sesuvium portulacastrum were studied, and the effects of pretreating methods on the determination of non-structural carbohydrates contents of plants by phenol-concentrated sulfuric acid method were analyzed, including the existence of the peel and mesh size. The results showed that: (1) When peeled, NSC, soluble sugar and starch contents of the Casuarina equisetifolia samples all had a decreasing trend compared with the control group, especially significant in the soluble sugar contents of the young-aged forest and the middle-aged forest(P<0.05),butmade nodifference in both theirstarch contentsand all componentcontentsin adult ones. The smaller the age of samples, the greater the effect of peeling pretreatment on NSC andits componentcontentsin trees,especially affectedonsoluble sugar,so we suggestto preserve tree bark when samples processed. (2) The contents of NSC and its components of different psammophytes’s branches (stem) all raised with the increase of mesh size, and there were significant differences between the Casuarina equisetifolia and Spinifex littoreus’branches (stem) samples which passed through the 100 and 18 mesh sieve (P<0.05). Except the Spinifex littoreus, all psammophytes’ leaves (assimilating branches) samples hadn’t changed much under different mush sizes and had no significant difference. The higher the content of mechanical tissue in the samples, the more significant difference in the content of NSC and its components extracted by different mesh size, considering the difficulty in obtaining samples and the accuracy of the determination of NSC content, thus we suggest that all branches and leaves of psammophytes should be processed by 100 mesh sieve. The conclusion of this study can guide the sample processing methods of related research in South China Coast, standardize experimental methods andimprove thecomparabilitybetweendifferentstudies.

Abstract： The data-fusion orbit determination software SPODFMD (Space debris Precise Orbit Determination fusing Multi-source Data) is developed with the purpose of cataloging space debris, characterized by integrating pure numerical integrators and given birth in the lab of SPOD (Satellite Precise Orbit Determination) at PMO (Purple Mountain Observatory). At the initial stage of the birth, developers fully investigated national space debris monitoring equipment, fully understood the orbit and physical complexity of numerous space debris, fully recognized the requirement for high efficiency when renewing orbits for lots of debris, and fully considered the robustness requirement in engineering. In addition, SPODFMD integrates several algorithms with indigenous intellectual property rights, including a rapid and non-singular algorithm for computing the Earth's gravitational potential and its derivatives, analytical and non-singular expressions for the DTM94 thermosphere model and its derivatives, an accurate and efficient method for calculating dense ephemeris of high-eccentricity orbit, and a robust adaptive weighting method. Integrating these advanced algorithms by applying software engineering theory, SPODFMD can freely fuse observation data from 14 kinds of equipment, achieving a second-level computation efficiency in a majority of typical orbit determination cases. Moreover, the software shows similar performance for GEO (Geosynchronous Equatorial Orbit), MEO (Medium Earth Orbit), LEO (Low Earth Orbit), and HEO (Highly Elliptical Orbit) objects without computation and pole singularity. It is tested and proved to be multi-source, efficient, general, and robust.

Abstract： In order to solve the problem that the use of Softmax as a long-short-term memory network classifier leads to the lack of generalization ability of the entity relationship recognition model, it is not suitable for the extraction of TCM entity relationships. This paper proposed a bidirectional long short-term memory (BILSTM) relational identification algorithm (BILSTM-GBDT) that incorporates a gradient boosting decision tree (GBDT) . Firstly, The Chinese medicine text vector is trained by word2vec, then the high-order features are extracted by the Bidirectional Long Short-Term Memory network based on the attention mechanism. Finally, the integrated classification model gradient lifting tree is used as the feature classifier to improve the relationship recognition effect. Experimental results on multiple relational corpora such as Chinese medicine show that the model has higher accuracy, recall and F value than traditional SVM method, GBDT method and deep learning method.

Abstract： The discrete binary particle swarm optimization algorithm has many advantages in various discrete optimization problems, but it is very easy to fall into the local optimal solution due to the nonlinear problem, and the best feature subset cannot be obtained. The noise reduction self-encoder can be mapped and reconstructed through a multi-layer nonlinear network, which has a good effect on Chinese medicine data. This paper proposes a feature combination method of fusion noise reduction self-encoder and BPSO. This method mainly uses noise reduction self-encoder to perform nonlinear mapping of features to form super-complete basis, and then searches in super-complete basis through BPSO. To get the best feature subset. The clinical diabetes datasets and UCI datasets were used for analysis and processing. The experimental results showed that the combination of fused-noise self-encoder and BPSO features a good adaptability to clinical experimental data of TCM.

Abstract： The traditional partial least squares method only considers the importance of single features and it exists the redundancy and multicollinearity among the features. The statistical correlation between features is involved into the traditional partial least squares analysis, and constructed the model of PLS feature selection based on feature correlation. Firstly, the feature group is pre-selected by using of the feature relevance, and then put into the partial least squares model for training to assess whether the feature group is desirable. Combining with the greedy search strategy, the candidate features are evaluated one by one, and the candidate features with the smallest objective function are added to the selected features. Respectively, using the data of the maxingshigan decoction of the monarch drug to treat the asthma or cough and UCI data sets to analyze . The experimental results show that the feature selection method can find an optimal feature group.
