Exploring classical correlations in noise to recover quantum information using local filtering
Authors: Jones Daniel E , Kirby Brian T , Riccardi Gabriele , Antonelli Cristian , Brodsky Michael 
Published: June 2020

Abstract
A general quantum channel consisting of a decohering and a filtering element carries one qubit of an entangled photon pair. As we apply a local filter to the other qubit, some mutual quantum information between the two qubits is restored depending on the properties of the noise mixed into the signal. We demonstrate a drastic difference between channels with bit-flip and phase-flip noise and further suggest a scheme for maximal recovery of the quantum information.

Authors: Hocini A , Maache M , Khedrouche D 
Published: June 2020

Abstract
We present a novel type of slow-light photonic crystal waveguide prepared by changing only the position of the second rows of holes in the direction of light propagation of a line-defect photonic crystal waveguide. A nearly constant group index is achieved of 30, 31 and 32 over wavelength ranges of 10.4 nm, 13.5 nm and 14.5 nm, respectively. In addition, a large normalized-delay-bandwidth product ranging from 0.201 to 0.300 is obtained at the operation wavelength of 1550 nm.

Authors: Kolev St , Paunska Ts , Trenchev G , Bogaerts A 
Published: June 2020

Abstract
CO2 dissociation and its subsequent conversion into added-value chemicals is a promising strategy for recycling CO2 gas into reusable products. One of the possible methods is direct plasma-induced dissociation. In this work we study the efficiency of CO2 dissociation in pulsed atmospheric-pressure gas discharge between two conducting electrodes by a 0-D numerical plasma model. The purpose of the study is to provide results on the optimal conditions of CO2 conversion with respect to the energy efficiency and dissociation by varying the maximum power density value and the pulse length. The power density is directly related to the discharge current and the reduced electric field in the discharge. We consider pulse lengths in the range from hundreds of nanosecond up to milliseconds. The results obtained show that the dissociation degree and energy efficiency are sensitive to the pulse length (duration) and the power density, so that a considerable improvement of the discharge performance can be achieved by fine-tuning these parameters. The study is intended to provide guidance in designing an experimental set-up and a power supply with the characteristics necessary to achieve optimal conversion.

Authors: Koleva E , Koleva L , Mladenov G , Trushnikov D , Andonov A 
Published: June 2020

Abstract
The electron beam processes – 3D selective melting (3D printing), welding, etc. are complex processes with many processing variables, which require integration of interfaces for control of the processes on different levels through hierarchical equipment models, functional data and operation control models. We developed a user interface software application for controlling the electron-beam motion along several types of trajectories and a free complex shape trajectory by controlling the deflection system parameters. Several types of motion patterns with different velocities are realized, together with the possibility of choosing a free trajectory by defining the electron-beam path by a graphical image.
Estimation of HTS electrodes properties for use in piezoelectric resonators
Authors: Nurgaliev T , Beshkova M 
Published: June 2020

Abstract
The microwave (MW) impedance of piezoelectric (PE) resonators with high-temperature superconducting (HTS) and with metal electrodes operating at a longitudinal acoustic waves (AW) frequency of ~2 GHz was modeled using Mason’s and the acoustic transmission line models. The MW impedances of the electrodes were also included into the model and the modeling parameters were chosen so as to be close to those of AlN (PE part of the resonator) and of HTS YBCO, Ag, and Pt (electrodes). It was shown that the limiting Q-factor value due to electric losses in the electrodes (computed under the assumption of small losses in the PE) is very high (~6×105) if even very thin (20 nm) HTS electrodes are used in the resonator at 77 K. The limiting Q-factor value is several thousand in the case of using similar metal electrodes. Thus, the HTS YBCO electrodes can be considered as attractive alternatives for application in PE resonators at low temperatures as they are characterized by low MW losses and affect weakly the resonance frequency.

Published: June 2020

Abstract
We report a study of p-Si(100) surface layers modified by plasma immersion ion implantation (PIII) and dry oxidation. This is expected to allow one to engineer near-surface layers with different thicknesses and levels of amorphization. Hydrogen ions were introduced into a shallow near-surface Si region through PIII with energy of 2 keV and doses ranging from 1013 ion/cm2 to 1015 ion/cm2. The implanted Si surface was subjected to oxidation in dry oxygen atmosphere at temperatures ranging from 700 °C to 800 °C. The optical and structural properties of the modified Si layers were studied in detail by spectroscopic ellipsometry (SE) in the IR spectral range of 300 – 4000 cm−1. The surface morphology was examined by atomic force microscopy (AFM) imaging at different scales and by fractal analysis. Through decomposition of the main Si-O bands into Gaussian peaks, different Si oxidation states were identified, suggesting non-stoichiometric oxide layer composition.

Excitation dependent emission of terbium aluminium garnet doped with gadolinium
Authors: Kaur Jasmeen , Rani Suman , Lal Bansi 
Published: June 2020

Abstract
This study reports the emission (400-700nm) properties of Gd (0.1, 0.5, 1.0 mol%) doped TAG nanophosphor synthesized by sol gel technique. Powder XRD spectra of doped TAG were indexed using JCPDS file No. 17-0735 implying that the basic structure of TAG remained unchanged on doping. The emission was excited with 280, 380 and 460nm radiation from a Xe lamp. The spectral features of the emission spectra were almost independent of both the doping as well as the excitation radiation. However, Gd concentration dependent variations in the emission intensity were observed. The observed emission intensity was maximum in TAG doped with 0.5mol% Gd while quenching was observed at 1.0mol% concentration level. This concentration dependent intensity variation which also depended on the wavelength of the excitation radiation could be due to energy exchange between Gd and Tb ions.
A COMPREHENSIVE REVIEW ON GRAPH PEBBLING AND RUBBLING
Authors: Sreedevi S , Anilkumar M.S 
Published: June 2020

Abstract
A graph pebbling is a combinatorial game played over a fixed graph and a pebbling move is the method of removing two pebbles from one endpoint and sets one pebble at the other endpoint, while the remaining pebble is dropped. A graph’s rubbling number is the smallest number necessary to ensure that any vertex can be reached from any pebble distribution of pebbles. A vertex is reachable if a pebble can be placed using pebbling or rubbling moves. In this paper we have attempted to give a summary of how graph pebbling have undergone a lot of challenges to derive many strong results in proof complexity. A comprehensive review of the existing works in pebbling and rubbling is carried out in a sequential order.

Abstract
Yellow fever is a vector borne disease caused by infected mosquitoes. It is a life threatening disease which is endemic in many parts of the world. Continuous efforts to eradicate and minimize the disease burden are being done using theoretical and statistical models. In this paper, we have considered a mathematical model for transmission of yellow fever for human and mosquito populations. Vaccination and insect repellent are introduced in the model as control measures. Stability analysis for disease free equilibrium is being done. The threshold parameter, that is, reproduction number is calculated which will predict the direction in which disease can be eliminated.

Authors: Ahmad Aijaz , Dutta Joydeep 
Published: June 2020

Abstract
Presences of antibiotics in water bodies have received widespread attention due to their potential toxicity. In this study, adsorption efficiency of synthesized beads was investigated, which were prepared by using chitosan, almond and walnut shell powder. The properties of the beads were characterized using Fourier-transform infrared spectroscopy analyses (FTIR), Scanning Electron Microscope (SEM) and energy dispersive X-ray analysis (EDX). The functioning of beads was attributed towards its antibiotic adsorption. To study the effect of dosage, pH, initial concentration and time on antibiotic adsorption, a batch adsorption experiment was conducted. Adsorption isotherms and kinetics were also studied. The adsorption isotherm experimental data is aligned with Langmuir for AWC (50% almond shell: 25% walnut shell: 25% chitosan) and CAW (50% chitosan: 25% almond shell: 25% walnut shell) beads. Whereas, WAC (50% walnut: 25% almond shell: 25% chitosan) beads follow Freundlich isotherm. The experimental data was fitted by pseudo-second order. In this study, Low initial concentration of beads was promising material for antibiotic adsorption from contaminated water.

Authors: Singh Jagdev , Mohan Dr Anand 
Published: June 2020

Abstract
The study was conducted to investigate the bioaccumulation of heavy metals (As, Cd,Cr and Pb) and their effect on the antioxidant level and activity in vegetables Raphanus sativus, Spinacea oleracea, Brassica oleracea and Lycopersicum esculentum irrigated with heavy metal loaded waste water of Buddha Nullah. The results of the study revealed bioaccumulation of heavy metals in vegetables and the level of non-enzymatic antioxidants, ascorbic acid and proline and enzymatic antioxidants, catalase and peroxidase was found to be much higher in waste water irrigated vegetables in comarison to the level of bioaccumulation of heavy metals as well as antioxidants in same vegetables irrigated with normal borewell water as control. This indicates that heavy metals induce oxidative stress (ROS) in the plants at cellular level and to nullify the toxic effect these heavy metals the cell mechanism increase the production and activity of both non-enzymatic and enzymatic antioxidants.

Authors: Shukla Bishnu Kant , Sharma Pushpendra Kumar , Goel Arun 
Published: June 2020

Abstract
Mechanical aerators are most commonly used for aeration process in treatment of waste water. Oxygen exchange mechanism by plunging jet of water is a superior method to transfer oxygen into pool of water than regular systems. Surface jet aerators, which are closed and simple systems, are uncomplicated in design, working and maintenance. In this study, experiments were conducted on models of solid jet aerators having circular shaped opening with variable jet lengths and area for different discharges. Penetration depth, oxygen transfer factor and Oxygenation efficiency were measured for different jet lengths, corresponding to each area and discharge. It was observed that penetration depth and oxygen transfer efficiency increments with increase in discharge and jet length in air whereas oxygen transfer factor increases with jet length in air only. With the results achieved, an efficient aerator model was suggested for a given set of inflow and environmental conditions.
A Simulation of Nominal Group Technique using Particle Swarm Optimization
Authors: An Zhenzhou , Yang Yang , Ma Yu , Zhang Jun , Zhou Hui 
Published: June 2020

Abstract
The nominal group technique (NGT) is a pattern of group decision-making technique in organizational behavior. Its research work is mainly focused on applications in different fields, and there is less research on algorithm simulation. In this paper, a method of NGTPSO is proposed in which NGT will be introduced into PSO and an attempt will be made to simulate NGT using PSO. From the perspective of PSO, PSO using NGT adds group decision-making technique. It characterizes the activity of individual and group through the grouping, individual optimizing, small-group discussion operation, large-group discussion operation and large-group decision operation. From the perspective of NGT, the decision process of NGT is simulated by PSO. The results show that the simulations of the algorithm are effective. The simulations show that small-group decision is better than or equal to individual decision and large-group decision is better than or equal to small-group decision. This is consistent with the basic principles of organizational behavior and it provides a good explanation for the relationship between NGT and PSO.
Anomaly Detection for Internet of Things Based on Compressed Sensing and Online Extreme Learning Machine Autoencoder
Authors: Yu Yun , Wu Xiaojun , Yuan Sheng 
Published: June 2020

Abstract
Abnormal events refer to specific events, such as forest fire, occurring in the wireless sensor networks of the Internet of Things (IoT), whose behaviors are quite different from normal events. By learning the underlying structure of sensor data, users can be helped to learn about the occurrence of these events as soon as possible. Due to the large number of sensors in the IoT and the periodic collections of data, sensor data has the problems of high dimensions and large amount, and the transmission of a large amount of data in the network is not a small challenge for bandwidth. In addition, the sensor data is unlabeled, so it is time-consuming and unrealistic to manually label all the data. Abnormal events in the IoT require low delay, such as gas concentration monitoring, In the IoT, data is generated continuously, so a well-trained model cannot remain unchanged, and features of new data need to be continuously learned. On account of the limitation of hardware, edge nodes cannot undertake the complicated and time-consuming task of model training and detection. None of the existing algorithms can meet the above requirements well, so this paper proposed an algorithm based on Compressed Sensing and Online Extreme Learning Machine Autoencoder named COELMAE. The proposed algorithm can carry out anomaly detection in low delay, unsupervised and online learning, and also has low computational complexity. What’s more, the algorithm can reduce the amount of data transferred about 60%.

Published: June 2020

Abstract
A multi-layered non-volatile solid-state reflective display pixel structure composed of a Fabry-Perot type resonance cavity and an ultrathin phase change material film has been fabricated and analysed. By electrically switching the phase states of a phase-changing Ge2Sb2Te5 (GST) film using an electric micro-heater under the stack, a pronounced colour change in pixel structures is observed, which is attributed to the change in the resonance condition of the multi-layered stack. Furthermore, the range of attainable colour can be widened by exploiting a spatial colour mixing structure.
A Study of English-Chinese Translation of Commercial Advertisements under the Background of “Internet +”
Authors: Chen Guoping 
Published: June 2020

Abstract
Under the implementation of the national strategy, “Internet +” is closely integrated with various traditional industries and has become one of the main driving forces for the economic development of the industry. For industrial development, “Internet +” provides technical tools, basic platforms, and link elements for building an ecosystem. The translation of commercial advertisements between English and Chinese is an important part of the language service industry. It is a major member of the cultural industry and guarantees the demand for commercial advertisement language services under the “Belt and Road” strategy in China. The combination of “Internet +” and commercial English-Chinese translation can promote the transformation and upgrading of commercial English-Chinese translation services. When translating commercial advertisements between English and Chinese, it is not only just a simple conversion of corresponding code symbols, but also needs to comprehensively consider the language background of national culture, customs and social development. In the context of “Internet +”, the translation needs to reorganize the original information on the premise of ensuring that the semantics are basically equivalent and the functions are similar. With the help of modern computer network technology and cloud computing platform technology, this article builds an Internet-based translation platform to provide support for the translation, thereby achieving good translation results.
