Sustainable Growth in China’s Communications Field: Trend Analysis of Impact of China’s Academic Publications

China＇s cormaaunications industry is an important part of the electronic information industry, and plays a significant role in the national informatization process. In 2006, China issued its National Plans for Medium and Long-term Development of Science and Technology （2006-2020） （NPMLDST）. Since 2006, there has been a rapid increase in the number of citations of China＇s interna- tional papers in the field of communications. In accordance with the goals listed in the NPMLDST, China needs to over- take several competitors by 2020 to be among the top five countries in the field of natural science field. By comparing two Essential Science Indicators （ESI） （i.e., the total number of citations and the number of citations per paper） for China and other countries, China＇s annual growth rate is found to exceed that of other influential countries in the field of sci- ence and technology, and exhibits evident growth-type characteristics. Besides, our study also shows that the short- age of high-quality academic papers in China is the main obstacle to improving the impact of China＇s academic publications.

Magnetized Micropillar-Enabled Wearable Sensors for Touchless and Intelligent Information Communication

The wearable sensors have recently attracted considerable attentions as communication interfaces through the information perception,decoding,and conveying process.However,it is still challenging to obtain a sensor that can convert detectable signals into multiple outputs for convenient,e cient,cryptic,and high-capacity information transmission.Herein,we present a capacitive sensor of magnetic field based on a tilted flexible micromagnet array(t-FMA)as the proposed interaction interface.With the bidirectional bending capability of t-FMA actuated by magnetic torque,the sensor can recognize both the magnitude and orientation of magnetic field in real time with non-overlapping capacitance signals.The optimized sensor exhibits the high sensitivity of over 1.3 T-1 and detection limit down to 1 mT with excellent durability.As a proof of concept,the sensor has been successfully demonstrated for convenient,e cient,and programmable interaction systems,e.g.,touchless Morse code and Braille communication.The distinguishable recognition of the magnetic field orientation and magnitude further enables the sensor unit as a high-capacity transmitter for cryptic information interaction(e.g.,encoded ID recognition)and multi-control instruction outputting.We believe that the proposed magnetic field sensor can open up a potential avenue for future applications including information communication,virtual reality device,and interactive robotics.

An Interactive Model for Analyzing the Development of the Communication Discipline： Israel as a Case Study

Our paper presents an interactive four-dimensional model for studying the long- and short-term development of the communication discipline with Israel serving as a case study： institutional-contextual, institutional-in-field, intellectual-contextual, and intellectual-in-field. Our empirical analysis utilized personal interviews, archive documents, and statistical data. Four main processes were discerned： transition from integration to alienation between institutions of higher learning and the larger political and ideological context; a shift from Hebrew University Institute of Communication＇s institutional monopoly to a multiplicity of increasingly competitive communication schools/departments; transition from intellectual hegemony to limited intellectual diversity; and gradually improving status for the communication field among social science disciplines. Our case-study analysis validated the interactive relationship among the model＇s conceptual dimensions, calling for future cross-national comparisons.

Water clusters in plants.Fast channel plant communications.Planet influence

In tubers of two potato cultivars and in one apple cultivar, water clusters, consisting of 11 ± 1, 100, 178, 280, 402, 545, 715, 903, 119, 1351, 1606 and 1889 molecules, were directly (in-vivo) analyzed by gravitation spectroscopy. The clusters’ interactions with their surroundings during plant growth in summer 2006 in Germany were described where a model represents the states of water clusters in bio matrices. Furthermore, a comparison with clusters in irrigation water (river, rain) is given. To achieve a high and good quality yield it is necessary to choose the right irrigation water that has to correspond with the water cluster super structure in plants. The formation energy for the (H2O)280 cluster during plant growth is between 0.4 and 1.3 kJ/mol. Water clusters were found to communicate with surroundings by resonance field oscillations. The main cluster parameters which were investigated are intensities of oscillations, average molecular masses, rate of collapsed clusters, and total number of clusters in ensemble during potato (apple) growth. A correlation between the change of water cluster ensembles in plants with molecular masses of all clusters in isolated starch (in-vitro) during plant growth process is discussed. In particular for potato tubers’ growth, there was observed a correlation between water cluster development and average molecular masses of amylopectin super coils. The com-munication of plants with each other and with surroundings proceeds by resonance field of oscillating water clusters. Planet gravitation was found to influence the water cluster structure in plants.
