This paper addresses the problem of cluster control for multi-biomimetic robotic fish. First, the mechanical design and system configuration of the biomimetic robotic fish are briefly introduced. In order to deal with the challenging problem of cluster control, a cluster control system is proposed based on WiFi technology. Specifically, host computer can transmit wireless signals (IEEE 802.11 signal) to surrounding space as access point (AP), while multi-biomimetic robotic fish can connect to the wireless local area network as station (STA). Then multiple transmission control protocol (TCP) connections can be established with host computer as TCP client and multi-biomimetic robotic fish as TCP server. In this way, host computer can control the multi-biomimetic robotic fish cluster simultaneously. In the end, experimental results demonstrate the feasibility and effectiveness of the designed cluster control system.

Manipulating the superconducting states of high-Tc cuprate superconductors in an efficient and reliable way is of great importance for their applications in next-generation electronics. Traditional methods are mostly based on a trial-and-error method that is difficult to implement and time consuming. Here, employing ionic liquid gating, a selective control of volatile and non-volatile superconductivity is achieved in pristine insulating Pr2CuO4±δ film, based on two distinct mechanisms: 1) with positive electric fields, the film can be reversibly switched between non-superconducting and superconducting states, attributed to the carrier doping effect. 2) The film becomes more resistive by applying negative bias voltage up to -4 V, but strikingly, a non-volatile superconductivity is achieved once the gate voltage is removed. Such a persistent superconducting state represents a novel phenomenon in copper oxides, resulting from the doping healing of oxygen vacancies in copper-oxygen planes as unraveled by high-resolution scanning transmission electron microscope and in-situ x-ray diffraction experiments. The effective manipulation and mastering of volatile/non-volatile superconductivity in the same parent cuprate opens the door to more functionalities for superconducting electronics, as well as supplies flexible samples for investigating the nature of quantum phase transitions in high-Tc superconductors.

In this paper we propose a method named spacetime stereo phase-shift for fast 3D shape measurement. It combines the advantages of the spacetime stereo approach and phase-shift approach. We first generate two different binary random patterns. In each projection cycle, four patterns including three phase-shift patterns and one binary random pattern are projected. In the two adjacent projection cycles, the two random patterns are switched alternatively, which is the main feature distinguishing the proposed approach with other approaches. As a result, we can use five image pairs for reconstruction without increasing the number of the patterns. Detailedly, we use the two image pairs of the random patterns (one of them is from the previous projection cycle) to establish the dense and subpixel-level correspondences by combining the wrapped phase maps from the three-step phase-shift method in the spacetime stereo framework. With an extra random pattern, the discrimination of the matching window can be enhanced greatly so that a simple local stereo matching method using the normalized cross correlation (NCC) can be utilized to acquire reliable matching. Experimental results show that the proposed method can improve the reconstruction results evidently. © 2017 IEEE.

For the lack of process data of the Gas-Steam combined cycle power plant in initial operating stage, this article presents a method for the output power prediction of CCPP using the Fuzzy Analytical Hierarchy Process(FAHP). Firstly, based on the analysis of the main factors that affect the CCPP output, a hierarchical structure for the prediction of CCPP output is established by combining with Analytical Hierarchy Process and calculating weight vectors according to experts' experience. Then, analyze and correct the operating characteristic curves of CCPP, which will be taken as the input and output membership functions. Finally, the output prediction model can be established, and the effectiveness of output prediction model of CCPP based on improved FAHP is demonstrated by the data set from a real case.

We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling evidence for the presence of a numerous population of neutron stars has been reported in the literature, turning this region into a very interesting place to look for CWs. In this search, data from the full O3 LIGO-Virgo run in the detector frequency band [10,2000] Hz have been used. No significant detection was found and 95% confidence level upper limits on the signal strain amplitude were computed, over the full search band, with the deepest limit of about 7.6×10−26 at ≃142 Hz. These results are significantly more constraining than those reported in previous searches. We use these limits to put constraints on the fiducial neutron star ellipticity and r-mode amplitude. These limits can be also translated into constraints in the black hole mass–boson mass plane for a hypothetical population of boson clouds around spinning black holes located in the GC.

Trait-based ecology claims to offer a mechanistic approach for explaining the drivers that structure biological diversity and predicting the responses of species, trophic interactions and ecosystems to environmental change. However, support for this claim is lacking across broad taxonomic groups. A framework for defining ecosystem processes in terms of the functional traits of their constituent taxa across large spatial scales is needed. Here, we provide a comprehensive assessment of the linkages between climate, plant traits and soil microbial traits at many sites spanning a broad latitudinal temperature gradient from tropical to subalpine forests. Our results show that temperature drives coordinated shifts in most plant and soil bacterial traits but these relationships are not observed for most fungal traits. Shifts in plant traits are mechanistically associated with soil bacterial functional traits related to carbon (C), nitrogen (N) and phosphorus (P) cycling, indicating that microbial processes are tightly linked to variation in plant traits that influence rates of ecosystem decomposition and nutrient cycling. Our results are consistent with hypotheses that diversity gradients reflect shifts in phenotypic optima signifying local temperature adaptation mediated by soil nutrient availability and metabolism. They underscore the importance of temperature in structuring the functional diversity of plants and soil microbes in forest ecosystems and how this is coupled to biogeochemical processes via functional traits.

The high resolution earth observation system project of China will coordinate the construction of high resolution geodetic systems based on satellites, stratospheric airships and aircraft, forming an all-weather, all-day, global coverage of ground-based observing capabilities. Intelligent interpretation of remote sensing images refers to the image detection, recognition and classification using computers, determining the object attributes or characteristics of the images. And then analyses and describes the various structures and relationships in the image, and explains the attributes, categories and relationships of the images, explains the variation of the various objects in time and space and the correspondence between them. In this paper, we propose a small object detection method based on deep Residual Network and Super-Vector coding. In our method, a variation of ResNet with fewer layers is defined to increase the resolution of the feature map and multi-level convolutional features are merged into an informative feature description for region proposal. Meanwhile, we extract histogram of oriented gradient (HOG) with SV coding from each region of interest, which assist convolutional features to complete object classification. We comprehensively evaluate the proposed method on our small-size object dataset. The experimental results show that our method outperforms top-performing methods on small object detection with higher accuracy and less time consuming. © 2018 International Astronautical Federation IAF.
