Authors: Sharovarova E P , Alekhin V N , Avdonina L I 
Published: November 2020

Abstract
The problem of conservation of energy sources is actual in many countries. The energy strategies of developed countries are aimed at renewable energy sources. For instance, European Union has already developed a long-term strategy ENERGYSTRATEGY 2050 aimed to reduce greenhouse gas emission by more than 80-95% from 1990 levels. Russian Federation has also developed the national program “Energy saving and improvement of energy efficiency for the period until 2030”. The distinctive feature of Russian energy system development is decentralized energy supply on large territories. Therefore, the renewable energy development is urgent. This article describes prospective directions of development of renewable energy generation systems in underpopulated and isolated territories of the Russian Federation where energy supply is decentralized.

Published: November 2020

Abstract
The urban planning information platform, including the “digital twin” model, has become the basis for the integration of various urban planning and sector-wide approaches and a tool for progressive spatial planning, design, and management of the sustainable development of territories. The study resulted in the identification of several “smart urban planning” aspects as a promising direction in the development of the theory and practice of urban planning. The article gives a brief description of the modern global experience in digital forecasting, programming, and design of the spatial system. It discloses the provisions of strategic urban planning, modeling the graphic identity of a territory, and master planning taking into account digital information systems and information and communication technologies. The authors propose to separate the concepts of “territorial” and “spatial”, taking into account their differences and tasks. They determine perspective tasks in the field of the development of urban planning information systems and “digital twins” aimed at spatial planning and modeling. They consider the theoretical provisions of predictive probabilistic modeling; initiative, institutional and participatory planning, taking into account the interests of residents, business, scientific and public institutions, as well as the tasks of creating a comfortable, safe and landscaped living environment.

Complex construction: urban design principles and the basis of sustainable development
Authors: Puchkov M V 
Published: November 2020

Abstract
This article evaluates the basic principles of the spatial organization of complex development projects on the city’s territory and characteristics of some modern commercially successful projects. Today complex development projects are one of the main types of constructions, which can be a part of sustainable urban development. “The XXI century – time of the cities”, sounded in the decision of the congress of the International Union of architects of 1999 in Beijing. More than a half of the population of Earth lives in the urbanized territories, and this share will grow in the future only, at the expense of a proceeding “explosive” urbanization of developing countries. Basing on the analysis of several modern Russian examples, we made some conclusions about the most important strategic decisions in the areas of planning, zoning and architecture, which provide integrated development project creating a high quality urban environment.
The origins of the formation and features of the manifestation of the Chinese Europeanized Architecture in mid-19th–second half of the 20th century
Authors: Kim A A 
Published: November 2020

Abstract
This article will look at the main preexisting architectural influences lying behind the development of Sino-Western architecture, fine examples of which exist in the southern (diaolou and qilou), central (shikumen) and Manchurian provinces (Chinese baroque). The first group consists of European architecture, as seen in the construction of European settlements and possessions in China, as well as the European-influenced buildings of Southeast Asia. The second group is the traditional architecture of China itself, which is a variation of the main type of Chinese residential buildings-siheyuan. The manifestation of the European influence in urban planning, space-planning decisions and decorative design of facades will be analyzed. It will be pointed out that the smallest changes affected city-planning decisions, which practically did not change. Functional and planning schemes of traditional Chinese buildings continued to dominate in the space-planning structure until the late stages of development. In the decorative design, from the first stages of development, an active borrowing of foreign elements can be traced, while their transformation occurred due to attempts to adapt them to traditional architectural forms and the local builders’ ignorance of the canons of European architecture.

Published: November 2020

Abstract
Wells turbine is very adept at converting pneumatic power from ocean waves into mechanical energy. However, such turbines incur from low performance, limited operating range and low efficiency. The present study introduces a method to enhance the power produced from Wells turbine by implementing rectangular Gurney flap (GF). The Gurney flap is placed on both pressure and suction sides of the trailing edge (TE) and perpendicular to the chord line without change chord length. GF increases the lift coefficient by altering the Kutta condition at the TE. The turbine performance is herein evaluated by solving numerically 3D incompressible Reynolds Averaged Navier–Stokes equations (RANS) by using ANSYS Fluent 19.0. The performance is demonstrated according to the flow coefficient, torque coefficient, total pressure loss coefficient, and the turbine efficiency, as well as the velocity and pressure fields around the turbine blades. The validation of the present work was achieved using previous experimental work and CFD work by using SST k – ω turbulence model. The present work showed that the Wells turbine augmented with GF increases the torque coefficient by 41.98%. Besides, the stall has been delayed compared with the conventional Wells turbine.

Authors: Abdelhamed M , Ata W G , Salem A M , Khafagy A Z 
Published: November 2020

Abstract
Magnetorheological (MR) dampers are a semi active control device that becoming a promising actuators in vibration mitigation. The unique properties of MR fluids are used to control the damping force without consuming large power source. Despite MR dampers are fail-safe, efficient, and robustness devices, they poses significant nonlinear characteristics. A well-known Bouc-Wen models and their extension modified Bouc-Wen are the most accurate models that predict the hysteresis of the MR dampers. However, these models suffer from some complexity and limitations and they miss a good fitting to the measured data. In this paper, the existing modified Bouc-Wen (MBW) models are introduced and their dynamic characteristics are simulated using MATLAB Simulink environment. The robustness of the model is judged by a comparison between the experimental tests of the MR damper (on and off state) on the MTS damper test machine in MTC and the simulated characteristics. To better understand the damper nonlinearity, an investigation into the effect of the model parameters on the dynamic characteristics of the damper is studied. A parametric study is proposed to identify the optimal model parameters that best fits the experimental data. The response of the model with the obtained parameters is validated across the measured MR damper characteristics under different sinusoidal excitations and command current. The results show a good agreement between the simulated and measured responses of the MR damper.

Abstract
Piezoelectric energy harvesting applications have been highly impacted research area recently. Numerical investigations for bistable piezoelectric cantilevers have great importance to understand its dynamic performance. This paper aims to develop comprehensive numerical models to simulate the dynamic response of aunimorph piezoelectric bender under bistability effect for enhanced energy harvesting. To this end, the equivalent stiffness, damping, electromagnetic coupling and capacitance coefficients of a bistable piezoelectric cantilever have been numerically developed. Besides, finite element models are developed to determine the bistability repulsion force between magnets. The resulting simulations are then implemented in an electromechanical model to predict the output voltage and power over a range of load resistance.

Authors: Louis M A , Roman M R , Mahmoud O E , Sedrak M F 
Published: November 2020

Abstract
In several food processing and chemical industries, liquid is pumped and kept in interrelating coupled tanks. However, automatic regulation of the liquid level and flow control between these tanks is a challenging problem because of the complexity and high non linearity of such system. This paper deals with the liquid level control of two horizontal coupled tanks system. A comprehensive comparative study is made for most popular sliding mode control (SMC) algorithms found in literature, namely Proportional-Derivative Sliding Mode Control (PD-SMC), Proportional-Integral-Derivative SMC (PID-SMC), Fractional Order SMC and finally dynamic SMC. Special emphasis is put on the effect of the sensor noise on the controller performance. Simulated experiments including robustness to variation in plant parameters and step input disturbances are made. Control algorithms parameters are selected to optimize designed performance indices by using MATLAB optimization toolbox. Simulation results reveal that dynamic SMC is superior to other control algorithms in the presence of sensor noise and has a significant reduction in the actuator chattering phenomenon.

Published: November 2020

Abstract
Epitaxial graphene (EG) on semi-insulating SiC prepared by a thermal decomposition method is the most promising strategy for graphene application in large-scale integrated circuits due to compatibility with current semiconductor processes. In this study, high-quality few-layer graphene (FLG) was epitaxially grown on the semi-insulating on-axis 4H-SiC by microwave plasma chemical vapor deposition (MPCVD). Both sides of the SiC substrate were etched with H2 plasma at ∼1000 °C to promote the nucleation and the growth of graphite before epitaxial growth. The surface morphology and properties of EG on SiC (0001) were measured by energy-dispersive x-ray (EDX), x-ray photoelectron spectrogram (XPS), and atomic force microscope (AFM). The qualities of EG grown on the two surfaces of SiC at various temperatures were checked by Raman spectroscopy. Furthermore, the EG growth was controlled by the effect of Ar plasma in the MPCVD and the few-layer (1–3 layers) high-quality EG films were formed on SiC (000

Published: November 2020

Abstract
Terahertz (THz) in vivo reflection imaging can be used to assess the water content of the surface of the skin. This study presents the results of treating 20 subjects with aqueous, anhydrous and water-oil emulsion samples and observing the changes induced in the skin using THz sensing. These regions were also measured with a corneometer, the present gold standard for skin hydration assessment within the cosmetics industry. We find that THz sensing is effective at observing the presence of oil and water on the surface of the skin, these results can be verified with the measurements of capacitance taken by the corneometer. The THz measurements reveal a distinction between the responses of subjects with initially dry or well hydrated skin, this observation is particularly noticeable with the oil-based samples. Additionally, moderate correlation was found between the THz reflected amplitude and capacitance of untreated skin with a correlation coefficient of r = −0.66, suggesting THz sensing has promising potential for assessing skin hydration.

Abstract
Here we develop the first optical neuromorphic processor for frequency-multiplexed and multi-channel signals and demonstrate its application for orthogonal frequency-division multiplexing and wavelength-division multiplexing. The presented architecture supports multichannel operation through incorporation of the optical Fourier transform and dispersion-managed fiber echo state network analogue enabling processing of dual-quadrature high bandwidth signals. We demonstrate applicability of the design for prediction and equalization tasks. The proposed technology paves the way to multi-channel neuromorphic signal processing.
Multifractal characterization of femtosecond laser-induced herringbone patterns
Authors: Mitra Vramori , Garcell Erik M , ElKabbash Mohamed , Neogi Anupam , Guo Chunlei 
Published: November 2020

Abstract
Analysis of surface structures formed due to femtosecond laser surface ablation is usually done through subjective assessment of the surface images. Here, we analyze the evolution of femtosecond laser-induced surface structures using multifractal analysis. We computed the singularity spectrum to characterize the behavior of laser-induced herringbone patterns. The surface morphology of the ablated surface shows a polarization dependent multifractal nature. The singularity spectrum depicts three distinct morphological phases that sequentially form as a function of the laser pulse number. We objectively characterize the laser-dependent morphological properties of herringbone structures. Multifractal analysis was able to reflect the hierarchy, uniformity, and roughness of the formed structures and their dependence on the pulse number and polarization.

Controlling photoluminescence spectra of hBN color centers by selective phonon-assisted excitation: a theoretical proposal
Authors: Groll Daniel , Hahn Thilo , Machnikowski Paweł , Wigger Daniel , Kuhn Tilmann 
Published: November 2020

Abstract
Color centers in hexagonal boron nitride show stable single photon emission even at room temperature, making these systems a promising candidate for quantum information applications. Besides this remarkable property, also their interaction with longitudinal optical (LO) phonons is quite unique because they lead to dominant phonon sidebands, well separated from the zero phonon line. In this work we utilize this clear spectral separation to theoretically investigate the influence of phonon decay dynamics on time-dependent photoluminescence (PL) signals. Our simulations show, that by using tailored optical excitation schemes it is possible to create a superposition between the two LO modes, leading to a phonon quantum beat that manifests in the time-dependent PL signal.

CB1R Promotes Chronic Alcohol-Induced Neuronal Necroptosis in Mice Prefrontal Cortex
Authors: Ye Lin , Li Shuhao , Liu Xiaochen , Zhang Dingang , Li Liliang , Jiang Yan 
Published: November 2020

Abstract

Aims
Alcohol abuse induces multiple neuropathology and causes global burden to human health. Prefrontal cortex (PFC) is one of the most susceptible regions to alcohol-induced neuropathology. However, precise mechanisms underlying these effects on PFC remain to be elucidated. Herein, we investigated whether RIP1/RIP3/MLKL-mediated necroptosis was involved in the alcohol-induced PFC injury, and explored the effect that cannabinoid receptors (CBRs) exerted on the neurotoxicity of alcohol.

Methods
In this study, dynamic development of neuronal necroptosis in the PFC region was monitored after 95% (v/v) alcohol vapor administration for 15 and 30 days, respectively. Selective CBRs agonists or inverse agonists were pretreated according to the experimental design. All the PFC tissues were isolated and further examined by biochemical and histopathological analyses.

Results
It was found that chronic alcohol exposure increased the protein level of MLKL and also the phosphorylated levels of RIP1, RIP3 and MLKL in a time-dependent manner, all of which indicated the activation of necroptosis signaling. Particularly, compared to astrocytes, neurons from the PFC showed more prototypical necrotic morphology in response to alcohol insults. In parallel, an increased protein level of CB1R was also found after 15 and 30 days alcohol exposure. Administration of specific inverse agonists of CB1R (AM251 and AM281), but not its agonists or CB2R modulators, significantly alleviated the RIP1/RIP3/MLKL-mediated neuronal necroptosis.

Conclusion
We reported the involvement of RIP1/RIP3/MLKL-mediated necroptosis in alcohol-induced PFC neurotoxicity, and identified CB1R as a critical regulator of neuronal necroptosis that enhanced our understanding of alcohol-induced neuropathology in the PFC.
