[Purpose/Significance] Interdisciplinary research can creatively solve complex problems in natural environment and human society through knowledge integration and penetration. With the increase of interdisciplinary research results, the evaluation of interdisciplinarity becomes increasingly necessary. How to establish an effective method for interdisciplinarity measurement and achieve a comprehensive measurement of scientific research papers is an urgent problem to be solved. [Method/Process] Based on the above background, this study takes the data of scientific research papers as the analysis source, deconstructs the interdisciplinarity of scientific research papers from multiple dimensions, constructs the feature set of interdisciplinarity of scientific research papers, and on this basis proposes the method for measuring interdisciplinarity based on the adaptive method of machine learning, and conducts a comprehensive measurement of interdisciplinarity. This study has certain positive significance for researchers to understand the interdisciplinary papers in the field. The work process is as follows: First of all, the basic concepts of interdisciplinarity are sorted out and related concepts are discriminated, and the index of interdisciplinarity of different dimensions is analyzed. Based on the connotation and characteristics of interdisciplinary research, the characteristic index of interdisciplinarity of scientific research papers is extracted from three dimensions: subject attribute, knowledge network topology and knowledge integration text content. Secondly, an interdisciplinarity measurement method based on machine learning is constructed. By analyzing information gain and feature similarity of input indexes and data in feature sets, a feature selection calculation method based on adaptive feature selection is proposed, and the accuracy of feature classification is maximized by machine learning classifier. At the same time, the feature subset that can best express the interdisciplinary is selected based on the adaptive selection of the minimum number of features, and the selected adaptive feature set is used in the calculation of the interdisciplinary of the paper, and the results of the calculation of the original feature set are analyzed comprehensively. Finally, an empirical study was carried out in the field of plant nanobiotechnology to verify the effectiveness of the index system and adaptive feature selection listed above, identify and screen papers with high interdisciplinarity in the field, measure the interdisciplinarity of papers and identify key influencing factors based on the calculation of subject attributes, knowledge network topology and knowledge integration text content features. [Results/Conclusions] The main empirical results show that, among the subject attributes, the balance degree and the difference degree have a greater effect on the interdisciplinary evaluation. The overall effect of knowledge network topology structure features is satisfactory, the distribution breadth of knowledge integration text content features has a greater effect on interdisciplinary evaluation, and the calculation effect is further improved by fitness weighted summation of each feature. The results demonstrate that the adaptive feature selection proposed in this paper can effectively screen the interdisciplinary related feature indexes, improve the reliability of the results, and achieve a comprehensive and in-depth measurement of the interdisciplinary of scientific research papers. This measure method avoids the subjective defects that may occur in qualitative evaluation and the problems that different measure indicators may produce contradictory results. It provides a new idea and direction for interdisciplinary measurement. [ABSTRACT FROM AUTHOR]

The packaging carton papers of products need to be checked by quality control machine after printing. Thus,a stack of carton papers shall be taken out one by one and placed onto conveyor belt. A paper picking mechanism composed of two cams and five links（including vacuum suction cups） is designed. By alternate use of inversion-graphic method and fitting of analytical formula,the profile of two cams is obtained.With a higher revolution speed,the proposed paper-picking mechanism can steadily pick 1200 carton papers every minute. Driven by the cam-linkage mechanism,its paper-picking suction cup can move in complex trajectories. Instead of interfering with paper bin,the suction cup is completely fitted to paper bin during paper picking and pauses at the right time to provide negative pressure in harmony with gas path. In this way,a smooth and reliable paper picking process is guaranteed.

The film prepared from the paper-based material has the advantages of low cost, biodegradable, foldable. It exhibits good potential as the flexible substrate of the electronic device. However, the paper-based film is generally poorly resistant to water, and its mechanical properties are limited, which limits its development in the field of optoelectronic devices. In this paper, the water-resistant film was prepared by solvent casting with raw materials of tissue paper and polyvinyl alcohol (PVA). Glycerol was added as a plasticizer, and succinic acid was added as a water resistant modifier. The results showed that the PVA/paper-based film exhibited good water resistance with the addition of succinic acid of 20%. the mass loss rate of PVA/paper-based film after modification decreased by 25% from 30℃ to 150℃, and the tensile strength increased to 35 MPa. Interestingly, the modified film presented high optical transparency (88%) and high haze (86%) at 550 nm. The composite film shows potential applications in the field of optoelectronic devices such as an organic light emitting diode (OLED) and solar cells. [ABSTRACT FROM AUTHOR]

Using silver nanowires prepared by polyol method as conductive filler and kapok m i cro-fi brill at ed cellulose as carrier, the composite paper was prepared by vacuum filtration. The samples were characterized by scanning electron microscopy, X-ray diffractometer. X-ray photoelectron spectrometer, four-probe tester and vector network analyzer, and the effects of silver nanowire content on their electrical conductivity and electromagnetic interference shielding effectiveness were investigated. The results showed that the silver nanowires as one kind of one-dimensional silver elemental nanomaterial, were uniformly distributed in the composite paper and formed an excellent conductive network. When 2.5wt% of silver nanowires were added to the pure cellulose paper, the electrical resistance of the paper dropped from 470.57 MD • cm to 1.26 mH • cm. When the concentration of silver nano wires was increased from 2.5 wt% to 1 Owt%, the conductivity of the paper increased from 793.65 S/cm to 3039.51 SZcm, and the electromagnetic interference shielding effectiveness increased from 38.1 dB to 61.5 dB.

A high-precision mechanized seeding can greatly contribute to the vegetable production at present. In this study, a spotting glue-paper tape precision seeder was designed for the small seed vegetables, particularly combining the seed rope and printing seeding. Three components were also divided in the seeder, including the peristaltic pump glue, ratchet spotting glue, and seed metering device. Among them, the glue was a mixture of pregelatinized starch and water. Specifically, the glue volume and viscosity were the main factors affecting the number of adhered seeds. The glue point volume depended mainly on the rotation angle of the peristaltic pump during the movement. A pretest of seed adhesion was carried out to preliminarily determine the mass ratio of pregelatinized starch to water (less than 1:5), representing the glue viscosity. Furthermore, the frequency of pump and dispensing were analyzed to clarify the relationship between the peristaltic pump and ratchet speed, where the number of ratchet teeth was determined to be 4. As such, the matching was realized between the peristaltic pump and ratchet spotting glue. The ratchet profile was also designed, according to the spotting glue motion. A theoretical analysis was made on the movement of seeds in the seed guiding tube. It was found that the aggregation effect of seeds on the paper tape relied on the length and cross-sectional angle of the seed guiding tube, as well as the rotation speed of the socket wheel. The seed guiding tube was then optimized for the optimal structural parameters. A Box_Behnken test was also carried out, where the length and cross-sectional angle of the seed guiding tube, while the rotation speed of the socket wheel was taken as the test factors, whereas, the percentage of seeds in the effective area on the paper tape was taken as the test index. The results showed that the percentage of seeds in the effective area on the paper tape was 57.23%, when the length of the seed guiding tube was 56 mm, the section angle was 35°, and the rotation speed of the seed metering wheel was 30 r/min. An adhesion test was also performed on the Shanghai Qing 605 seeds with a diameter of 1.5-2.0 mm. The test factors were then selected as the roller angle of the peristaltic pump and the mass ratio of pregelatinized starch to water. An optimal combination of parameters was achieved, including the size of the glue point, and the mass ratio of pregelatinized starch to water. Once the roller rotation angle was 10° and the mass ratio of pre-gelatinized starch to water was 1:6, the single seed rate of glue point adhesion to seeds reached 97.4%. The adaptability test was also carried out on the whole machine on the working performance of different varieties of small seed vegetables. It was found that the single seed rates of Shanghai Qing 605 and Siji Chinese cabbage seeds were greater than 95% under the working speed of 0.5-1.5 m/s, whereas, the coefficient of variation of plant spacing was less than 10%, fully meeting the requirements of precision sowing indicators that specified in the standard NY/T1143-2006. Therefore, the single seed rate and the working efficiency of the improved seeder increased by 3.53%, and 50% than before. [ABSTRACT FROM AUTHOR]

50 nm ceramic membrane and 100 kD and 10 kD organic membrane were used to separate the reconstitution tobacco extract, the obtained fractions were analyzed by GC-MS analysis, principal component analysis of volatile components, evaluation cigarette paper flavoring, and particle composition analysis of flavoring cigarette smoke. The results showed that 68, 45, 45, 7 and 36 volatile components were detected in the unseparated component ( M0), 50 nm ceramic membrane interception component (M2), 100 kD organic membrane interception component ( M4), 10 kD organic membrane permeation component ( M5) and 10 kD organic membrane interception component ( M6), respectively, and the total volatile components were 1 109.03 µg/mL, 1 042. 14 µg/mL, 828. 02 µg/mL,92. 00 µg/mL,762. 42 µg/mL, widely existing in the five components were nicotine, 2,2'-meth-ylene bis-(4-methyl-6-tert-butylpheno. The unique components of M5 were 2-ethylhexanol and cis-1-(cyclohexylm-ethyl) -4-ethyl cyclohexane. The results of principal component analysis of M5 component were similar to M2 to a certain extent, but there were obvious differences with the other three components. The main components that affected the flavor of M5 were 2-ethylhexanol, cis-1-(cyclohexylmethyl)-4-ethyl cyclohexane. When M5 were added to cigarette paper, the sensory evaluation effect of cigarette was the best, the phenolic, alkane and benzene components in the smoked significantly increased, and the individual flavor components ( such as methyl cyclopen-taenol ketone, (+)-vanorene, etc. ) also increased, which had a significant flavoring effect.

Brenda Dervin presented a paper in 1983 titled “An Overview of Sense-Making Research: Concepts, Methods and Results to Date” at a conference. She presented the “Sense-Making Methodology (SMM)” in the 1983 paper with the introduction of its core concepts, methods, and applications. SMM is a user-centered theory for methodology and has been widely applied to a wide range of fields. The findings of this study show that the 1983 paper has a longterm influence on other research articles and its influence has expanded into more disciplines and topics over time. Most of 283 articles citing the 1983 paper were information behavior articles published in journals of library and information science. This study contributes to confirm that the primary influence of this 1983 paper was established by a few concepts related to SMM. Not all three basic concepts constructing the SMM, “gaps”, “situations”, and “uses”, were the most influential concepts in terms of number of citation contexts. “Gaps” was the most frequently cited concept related to SMM (17.5%), closely followed by “sense-making/nonsense-making (17.3%)”. However, “SMM” was the most influential concept in terms of number of research topics of citing articles.
