Magnonics is gaining momentum as an emerging technology for information processing. The wave character and Joule heating-free propagation of spin-waves hold promises for highly efficient computing platforms, based on integrated magnonic circuits. The realization of such nanoscale circuitry is crucial, although extremely challenging due to the difficulty of tailoring the nanoscopic magnetic properties with conventional approaches. Here we experimentally realize a nanoscale reconfigurable spin-wave circuitry by using patterned spin-textures. By space and time-resolved scanning transmission X-ray microscopy imaging, we directly visualize the channeling and steering of propagating spin-waves in arbitrarily shaped nanomagnonic waveguides, with no need for external magnetic fields or currents. Furthermore, we demonstrate a prototypic circuit based on two converging nanowaveguides, allowing for the tunable spatial superposition and interference of confined spin-waves modes. This work paves the way to the use of engineered spin-textures as building blocks of spin-wave based computing devices.

Published: September 2018

Quantum memory capable of stopping flying photons and storing their quantum coherence is essential for scalable quantum technologies. A room-temperature broadband quantum memory will enable the implementation of large-scale quantum systems for real-life applications. Due to either intrinsic high noises or short lifetime, it is still challenging to find a room-temperature broadband quantum memory beyond conceptual demonstration. Here, we present a far off-resonance Duan–Lukin–Cirac–Zoller (FORD) protocol and demonstrate the broadband quantum memory in room-temperature atoms. We observe a low unconditional noise level of 10−4 and a cross-correlation up to 28. A strong violation of Cauchy–Schwarz inequality indicates high-fidelity generation and preservation of non-classical correlation. Furthermore, the achieved cross-correlation in room-temperature atoms exceeds the key boundary of 6, above which quantum correlation is able to violate Bell’s inequality. Our results open up the door to an entirely new realm of memory-enabled quantum applications at ambient conditions.

Authors: Pratihast Manisha , Al‐Ani Ahmed , Chai Rifai , Su Steven , Naik Ganesh
Published: September 2018

The goal of this research was to investigate the effect of wearing high‐heeled shoes (HHS) on lower limb muscle synchronisation during walking, using beta band (15–30 Hz) coherence analysis. Fifteen females with no previous neuromuscular disorders volunteered in this study. Surface electromyography in frequency domain was studied from rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM) and semitendinosus (ST) muscles during walking by subjects wearing HHS of three different heel heights (low – 4 cm, medium – 6 cm and high – 10 cm). Average coherence values were calculated for RF‐VL, RF‐VM and RF‐ST muscles in beta band to analyse muscle pair synchronisation. In this study, significant increase in beta band coherence was found in all three muscle pairs during walking on HHS of different heel heights (p<0.05). Increased beta band coherence obtained from this study suggested that walking on HHS demands higher muscle pair synchronisation, to maintain stability around the knee joint.
Secure communications with untrusted relays: a multi‐pair two‐way relaying approach
Authors: Zhao Tantan , Li Guobing , Lv Gangming , Zhang Yizhen
Published: September 2018

Physical‐layer security is usually ensured by the injection of artificial noise (AN) at the legitimate source or destination when relays are cooperative but untrusted. In this work, in order to avoid the power‐consuming AN at the legitimate user pairs, the authors investigate multi‐pair two‐way relaying as a solution for secure transmission in wireless relay networks with untrusted relays. They formulate a generalised problem for the joint design of cooperative beamforming (CB) and AN at relays to maximise the secrecy sum‐rate in wireless networks with multi‐pair legal users, multiple untrusted relays as well as multiple non‐colluding eavesdroppers. Further, they reformulate, approximate and relax the original non‐convex problem into a sequence of convex sub‐problems based on semi‐definite relaxation (SDR) and Taylor series approximation. Particularly, for the reformulated problem they prove that the SDR is in fact tight, and hence propose an iterative algorithm for CB and AN design at the relays. In the simulations, they demonstrate the fast convergence and high achievable secrecy sum‐rate of the proposed algorithm. Also, they simulate and discuss the impact of the number of user pairs on the secrecy sum‐rate, and reveal the change of performance gain with the number of multiple user pairs.
Altitude measurement based on characteristics reversal by deep neural network for VHF radar
Authors: Xiang Houhong , Chen Baixiao , Yang Minglei , Li Cunxu
Published: September 2018

A novel direction of arrival (DOA) estimation method is proposed for very high‐frequency (VHF) radar by the deep neural network (DNN) under strong multipath effect and complex terrain environment. The classical methods are all based on the classical multipath signal model, hence, it often causes the problem of model mismatch and results in poor performance in estimation. It is generally considered that the serious multipath effect reduces the precision of elevation estimation. However, the characteristics of the multipath signal are exploited and used to improve the precision in this study. This is the highlight of the proposed method. The approach of the deep neural network is applied to learn the received data's characteristics from a different elevation. A new characteristic space is constructed in the training procedure. In the test procedure, the characteristic of data is extracted by the well‐trained network and projected into the constructed characteristic space. Reversing the DOA is finished at last. The results of simulation data verify the validity of the proposed method. The results of the practical data show the practicability of the proposed method for the low‐elevation target under the serious multipath effect. Combining the DNN approach with altitude measurement of a low‐elevation target for VHF radar is meaningful to explore.
DOA estimation for coprime EMVS arrays via minimum distance criterion based on PARAFAC analysis
Authors: Ahmed Tanveer , Xiaofei Zhang , Wang Zheng
Published: September 2018

This study presents a minimum distance‐based direction‐of‐arrival (DOA) estimation algorithm for coprime electromagnetic vector sensor (EMVS) arrays. The idea is to split‐up the coprime array into two uniform linear arrays (ULAs) of vector sensors and arrange the received ULA data in the form of a three‐way array suitable for parallel factor (PARAFAC) analysis, which fits least‐square models to the received source signal mixtures of ULAs and thus enables to retrieve the model matrices corresponding to each ULA. Nevertheless, because of the array splitting the estimated DOAs from these matrices are not unique. To uniquely determine the DOA, the authors state and prove a theorem which is fundamental to the proposed algorithm and provides a means to find an estimate based on the minimum distance criterion. Efficacy of the proposed algorithm is demonstrated through performance comparison with other existing algorithms such as Estimation of Signal Parameters via Rotational Invariance Technique (ESPRIT), long vector MUltiple SIgnal Classification (MUSIC), conventional PARAFAC and the propagator method being simulated for an equivalent element ULA of EMVS and spaced half a wavelength apart. Numerical simulations reveal that the proposed algorithm outperforms the others.

Published: September 2018

After 50 years of exploitation, Block A has entered the development stage of the ultra-high water cut stage. Although the layer series of development has been subdivided and adjusted, the interlayer interference is still serious, imposing difficulties in development adjustment. Based on dynamic production data and monitoring data analysis, this paper applies multi-disciplinary reservoir description technology and introduces economic evaluation indicators to quantitatively analyze the variation coefficient of permeability within subdivided layer sections, the number of monolayer breakthrough series and sections, the number of small layers within a layer section, and the effect of sandstone thickness on the subdivision and adjustment effect, analyze the influence of well test period and operation costs on the economic benefits, and the optimize combined parameters of subdivision water injection layer sections.

Nitrous oxide (N2O) is a common greenhouse gas and urgent need to be contained. Direct catalytic decomposition of N2O by high activity catalyst into N2 and O2 is a low-cost and harmless method. Bimetallic catalysts show good catalytic activity in many classes of reactions, and plasma technologies, applied to prepare of catalyst, are considered to be a promising method. In our contribution, DBD cold plasma is applied to synthesize Rhodium and Cobalt bimetallic catalysts for catalytic N2O decomposition. The influence of cobalt and rhodium content on N2O decomposition activity shows that the optimal amount of metal is determined as 5wt. % cobalt and 0.5wt. % rhodium loaded on Al2O3. The best working voltage is determined as 18kV. The results indicated that the Rh/Al2O3 catalysts prepared by atmospheric-pressure DBD cold plasma showed smaller size and high dispersion of Rh particles, so that the metal-support interaction and the catalytic activity are enhanced. Atmospheric-pressure DBD cold plasma is proved to be an environmentally friendly and efficient method for preparing high performance Rhodium and Cobalt bimetallic catalysts for catalytic N2O decomposition.

Published: September 2018

The environmental and resource constraints on economic growth are increasingly evident. China urgently needs to reshape its economic growth momentum. The increase in green total factor productivity is particularly necessary for the growth of the quantity and quality of the economy. This paper selects the provincial panel data of 30 provinces in China from 2001 to 2015, and establishes a panel exchangeable errors model to analyze the impact of eight indicators on green total factor productivity (GTFP) and verifies its effectiveness. Empirical analysis shows that inter-provincial government competition, environmental regulation, energy consumption, and capital stock have a significant impact on green total factor productivity. The influence of foreign direct investment, industrial structure, and industrialization level on the total factor productivity of green is not significant. Therefore, the government should adopt suitable, flexible and diverse environmental regulation policies, promote energy-saving emission reduction and technology innovations through policies such as taxes and subsidies, strengthen the linkage mechanism between industrial structure upgrading and energy efficiency, to increase green total factor productivity.

Authors: Zhang Haiyue , Chen Yang , Qin Qing
Published: September 2018

In Urumqi, China, the occupancy rate of hotels during the low season is quite different from that of high season. This phenomenon can result in wasting energy. However, most energy saving design standards don't take seasonal use characteristics of buildings into consideration. This paper focused on the energy saving design based on seasonal use patterns for big hotels in Urumqi. Combining time-variation characteristics with the unique climate this study explored a different approach to energy management. Design strategies for big hotels in the Urumqi region were developed according to use patterns and climatic conditions, considering thermal, wind and luminous factors. This study provides design ideas for big hotels in temperate continental climate areas based on this alternative approach.

Published: September 2018

The development of new energy is not only an objective need for sustainable development of mankind, but also an important breakthrough for the world to foster new economic growth points. The focus of this article is on what kind of fiscal and tax policies the government implements can better guide the development of new energy and have a more favorable impact on the economy. This paper, taking wind power and solar photovoltaic power industries in the Inner Mongolia as an example, using the dynamic 3ED-CGE model, explored the economic impacts of different financial subsidies and preferential tax policies on new energy enterprises. And then this paper provided suggestions for the formulation of fiscal and tax policies. The study founded that compared with the fixed subsidy mechanism financial subsidies by the fall-off mechanism could be better to promote the growth of GDP, residents' welfare and employment. If the government didn't subsidize the new energy electric power's sales price to network after 2020, it would not have a negative impact. The 15% income tax rate was more effective in promoting the development of economic than 25%. 8.5% and 6% value-added tax rate exerted similar effects on the economy, but 6% value-added tax rate had a significant promotion on optimized adjustment the consumption structure of fossil energy and electric energy.
Can constraint energy-saving policy facilitate industrial green production performance in China?
Authors: Yao Yue , Jiao Jianling , Han Xiaofei
Published: September 2018

The role of constraint energy-saving policy (ESP) playing in the coordinated development of energy conservation, emission reduction, and economic growth is of great significance to the country's sustainable progress. Applying a non-radial and non-oriented DEA model incorporating innovation output and multiple undesirable outputs, this paper measures the green production performance (GPP) of China's industrial sectors from 2002 to 2015. And then the effect of implementing energy-saving policy on GPP is investigated through Quasi-difference-in-differences (Quasi-DID) method. The results show that China's industrial GPP rises during 2002-2004 and then declines with fluctuations. Technology change (TC) is the dominant driver. Energy-saving policy positively affects industrial GPP in general yet further dynamic analysis reveals that such a positive effect remains unstable and finally manifests a reverse impact at the end of every five-year-plan period. Therefore, China should properly introduce market mechanisms, formulate comprehensive policy mix strategies to balance sustainable improvement of industrial economy and ecological environment.

Published: September 2018

When disaster strikes, close relationships form between governments, businesses, and people. Since hazardous materials industries are dangerous, it is important to enhance their disaster prevention efforts. We examined the literature on hazardous materials management, business risk management, corporate social responsibility, and the promotion of disaster management in Taiwan. The study deals with these topics in five dimensions: “organization,” “law,” “consultation,” “financial aid,” and “education.” These dimensions were used to create a questionnaire. An investigation of hazardous materials industries in Taiwan was conducted to explore the factors that could be used to promote their disaster management and improve their willingness. After the data were analyzed, the findings indicated the following: (1) Company capital affected motivation toward disaster management, especially as an organizational factor. (2) A company's employee population affected its selection of motivation factors. (3) When the government made disaster management policies, the differences between the hazardous materials industries and consultation and support persons were the main viewpoints related to the promotion of policies. (4) Two background variables, company capital and employee population, had an interaction on the motivation factor of organization. (5) Three motivation factors—“organization,” “consultation,” and “financial aid”—could effectively predict an industry's intention toward business continuity management.
