Published: February 2021

At the end of Qing Dynasty, with the opening of Yingkou port, the economic exchanges between Northeast China and foreign countries were exported. The transportation of goods was more convenient by water than by land. Liaohe river has become an important road of trade transportation, At the same time, it has also become an important way to culture introduction. Therefore, there are nearly three times more ports along the Liaohe river than before. With each port as the core, gathering the resources of the region becomes the core of transportation. The agglomeration of transportation promotes the emergence of corresponding service facilities and the rapid development of economy.
Among them, Tianzhuangtai, located in the southern edge of Panjin City, bordering Liaohe river in the East and Bohai Sea in the west, is a typical representative of these traditional settlements. It has entered a period of rapid development from a military important town to a trade center since ancient times. The following changes in the settlement space have also shown a trend of development against the tradition, and the evolution of a series of patterns is also the materialization of the special political, economic and cultural influence of the Northeast in modern times.

Published: February 2021

Abstract
Background The World Health Organisation (WHO) declared coronavirus disease 2019 (COVID-19) as a global pandemic February 2020 after it emerged from Wuhan city of China and spread to most of the world. The most common psychological symptoms found during the pandemics are fear, anxiety, loss of sleep, depression, suicidal tendency, etc.
Aim To collect various psychological symptoms, the people are presenting during this type of situations and their proposed homoeopathic treatment.
Methodology A web-based survey was conducted to assess the mental health burden in public during the outbreak of COVID-19 pandemic and also to explore the potential influencing factors. The data of 314 volunteers were collected and assessed.
Results It was found that the overall proportion of depression and anxiety was 34.4 and 31.21% respectively. About 23.9% of participants had both depression and anxiety. The proportion of depression and anxiety was more in males and age group of 21 to 30 years. Healthcare providers reported more depression and anxiety as compared with other occupations. Among the influencing factors, regular Yoga practice and adequate sleep of 7 hours in the day had good effects in controlling depression and anxiety. Spending time in social media for more than 3 hours a day regularly was also an influencing factor for more depression and anxiety. It was also found that people who frequently got worried about their own health and of near and dear ones had developed more anxiety. The participants who had taken homoeopathic medicines during last month reported less depressive symptoms in comparison to others.
Conclusion Homoeopathy has many remedies which can relieve these psychological symptoms as the principle of homoeopathy is based on individualisation which constitutes the physical as well as the mental sphere.
Total Ankle Replacement Requiring Distal Tibiofibular Arthrodesis in a Dog
Authors: Burton Neil J. , Krukowski Maciej 
Published: February 2021

AbstractThis case report describes distal tibiofibular arthrodesis as a technique for achieving increased confluent bone support for the placement of oversized arthroplasty components for talocrural arthroplasty in an 18-month-old Labrador Retriever with talocrural osteoarthritis secondary to talar osteochondrosis. Computed tomography assessment for suitability for BioMedtrix canine ankle replacement surgery revealed the tibia to be undersized relative to the tibial component. Distal tibiofibular arthrodesis was performed to increase lateral bone support to permit placement of an otherwise oversized prosthesis. Subjective assessment of outcome with owner Liverpool Osteoarthritis in Dogs questionnaire to 6 months postoperatively as well as radiological assessment to 4 months postoperatively documented significant improvement in lameness in the operated limb with no complications. Distal tibiofibular arthrodesis is a means by which to achieve increased bone support prior to BioMedtrix canine total ankle replacement surgery. The surgical technique described herein permitted placement of an oversized talocrural prosthesis in this patient with good clinical function. This technique may permit use of this arthroplasty system in otherwise undersized patients until such a time that smaller implants are available from the manufacturer.

Published: February 2021

The review aims to present a classification and applicability analysis of methods for preliminary molecular modelling for targeted organic, catalytic and biocatalytic synthesis. The following three main approaches are considered as a primary classification of the methods: modelling of the target – ligand coordination without structural information on both the target and the resulting complex; calculations based on experimentally obtained structural information about the target; and dynamic simulation of the target – ligand complex and the reaction mechanism with calculation of the free energy of the reaction. The review is meant for synthetic chemists to be used as a guide for building an algorithm for preliminary modelling and synthesis of structures with specified properties.

SignificanceAlthough a role for β-adrenergic receptor (ADRB) in cancer progression was suggested a long time ago, our serendipitous observation of the propranolol efficacy in treating infantile hemangioma (IH) has driven attention in exploring the antitumor properties of β-blockers. We identified Aquaporine-1 (AQP1) as a player in antitumor propranolol response and as a histological marker of IH vascular structures including telocytes, which are dendritic cells that form a distinctive peripheral layer in IH. We conclude that IH sensitivity to propranolol may rely, at least in part, on a cross talk between lesional vascular cells and stromal telocytes.

Published: February 2021

SignificanceThe basal forebrain (BF) is traditionally recognized as a brain structure crucial for arousal, attention, learning, and memory. Here, we discovered a causal role of the BF in the control of prosocial behavior, which is fundamental for our daily life. We showed in mice that the BF somatostatin-expressing inhibitory neurons predominantly target GABA neurons and disinhibit dopamine neurons in the ventral tegmental area and thereby increase dopamine release in the nucleus accumbens. This disinhibitory circuitry played an essential role in promoting social interaction behavior. Our findings identify a previously unknown function of the BF in social behavior regulation and suggest a potential therapeutic target for social deficits commonly observed in major neuropsychiatric disorders.
Underwater acoustic multiplexing communication by pentamode metasurface

Published: February 2021

Abstract
As the dominant information carrier in water, the acoustic wave is widely used for underwater detection, communication and imaging. Even though underwater acoustic communication has been greatly improved in the past decades, it still suffers from slow transmission speeds and low information capacity. The recently developed acoustic orbital angular momentum (OAM) multiplexing communication promises a high efficiency, large capacity and fast transmission speed for acoustic communication. However, the current works on OAM multiplexing communication mainly appear in airborne acoustics. The application of acoustic OAM for underwater communication remains to be further explored and studied. In this paper, an impedance matching pentamode demultiplexing metasurface is designed to realize multiplexing and demultiplexing in underwater acoustic communication. The impedance matching of the metasurface ensures high transmission of the transmitted information. The information encoded into two different OAM beams as two independent channels is numerically demonstrated by realizing real-time picture transfer. The simulation shows the effectiveness of the system for underwater acoustic multiplexing communication. This work paves the way for experimental demonstration and practical application of OAM multiplexing for underwater acoustic communication.
An improved projector calibration method for structured-light 3D measurement systems
Authors: Yu Jing , Zhang Yaqin , Cai Zewei , Tang Qijian , Liu Xiaoli , Xi Jiangtao , Peng Xiang 
Published: February 2021

Abstract
In a structured-light three-dimensional measurement system, understanding the optical configuration of the projector and suppressing the eccentricity error caused by the camera perspective projection are critical to realize high-precision measurement. In this paper, we analyze the special offset optical structure in commercial projectors, where a larger diameter lens is used to ensure the quality of the projected image, and the position of the principal point has been shifted. Meanwhile, a projector calibration strategy that makes the camera’s optical axis perpendicular to the target plane is proposed to avoid the pollution of perspective projection distortion. The sub-pixel correspondence based on homography transformation is performed by relying on the phase value of the fringe, and bundle adjustment optimization is used to further improve the accuracy and robustness of projector calibration. The experimental results demonstrate that the proposed calibration method can improve the calibration accuracy by 52.52%.

Abstract
The integration of electrical contact into 2D heterostructure is an essential approach to high-quality electronic nano-devices, especially field-effect transistors. However, high contact resistance with transition metal dichalcogenides such as molybdenum disulphide (MoS2)-based devices has been a significant fabrication impediment to their potential applications. Here, we have demonstrated the advantage of 1D indium metal contact with fully encapsulated MoS2 within hexagonal boron nitride. The electrical measurements of the device exhibit ambipolar transport with an on/off ratio of

Furthermore, we have also analysed the charge-transport mechanism at the interface and have calculated the Schottky barrier height from the temperature-dependent measurement.

Authors: Lagerev A V , Tarichko V I , Lagerev I A 
Published: February 2021

Abstract
Cargo aerial ropeways are an efficient mode of transport in mining industry. The purpose of the paper is to develop a method for modeling kinematic and hydrodynamic processes in the mechanisms of movement of carrying-pulling ropes equipped with hydraulic drives with frequency-throttle control at all stages of work such as acceleration of the transported load, steady motion and braking. The options of sequential installation (one-way and two-way) of adjustable throttles relative to the hydraulic motor are considered. The developed mathematical model provides computer modeling in time of the main characteristics of the hydraulic drive - the pressures and volumetric flow rates of the fluid at the characteristic points of the hydraulic system, as well as the kinematic and power parameters of the movement of carrying-pulling ropes (traveled distance, linear velocity and acceleration, required power, surmounted operating loads). For a specific option of mobile rope complex, the calculations of the indicated hydrodynamic, kinematic and force parameters are carried out and the obtained results are analyzed.
Synthesis of the CNC machine control algorithms optimized with respect to the contour error using the genetic algorithm
Authors: Lyubich V K , Kurmashev A D , Frolov V Y 
Published: February 2021

Abstract
Traditionally control systems of CNC machines are built using the positional system structure, e.g. the uncoupled system (US) tuned on the symmetrical optimum. These systems have a relatively small contouring quality factor–the ratio of the contour speed to the contour error. To increase the quality factor of such systems, we proposed two new algorithms: the US tuned on the contour error optimum (US-C) and the neural coordinated control algorithm (NCCA). Both algorithms were tuned on a non-convex criterion using the genetic algorithm which allowed us to reduce the tuning time and acquire better optimal values of the criterion in comparison to the gradient descent method. The experiments were conducted using a mathematical model of a CNC machine based on real servo motors and lead screws. The results of the experiments showed that the usage of the proposed algorithms led to a significant increase in the quality factor, which has a positive effect on the overall productivity of the CNC machine. Furthermore, the NCCA use available resources better than the other tested algorithms which can be seen in the experiments with a lower initial contour error, a lower radius of the circle, and a higher contour speed. Besides, the US-C can maintain the contour speed better than other tested algorithms.

Authors: Musteykis A I , Levikhin A A , Anistratov K Y 
Published: February 2021

AbstractThe jet drilling method has significant advantages over mechanical ones. The article presents the results of the theoretical and experimental jet drilling apparatus for drilling blast holes in hard rocks granite and gneiss studies using the developed test rig. The main difference between the studied device and traditional thermal spallation drills is the low temperature of the working fluid. The specific energy consumption method was proposed to evaluate parameters of the jet drilling apparatus for various rocks types. It has been shown that minimal specific energy consumption for hard rocks is obtained with minimal chamber pressure sufficient for reaching certain Mach number at the nozzle exit. The developed test rig has experimentally shown a stable drilling process and, at the same time, a long durability of the apparatus.
Autonomous wheeled mobile robot maneuvering in constraint environment. Trajectory tracking quality criteria
Authors: Shabanov D V , Kozlovich A V , Valiev R R , Kochneva O V 
Published: February 2021

Abstract
In this article the problem of control system synthesis for differential drive wheeled mobile robots operating within constraint environment is considered. The proposed approaches of solving trajectory tracking problem take into account the geometric features of both the robot and the transported cargo. The collision avoidance problem is solved at the controller level, without any changes to the planned trajectory. Three approaches are proposed: minimizing the distance to the trajectory, minimizing the distance to the reference position, and maximizing the distance to obstacles. In these approaches the constant analysis of position of each point of robot’s body outline contour is used. Negative influence of the position of these points on qualitative trajectory pass is represented in vector form. For each of the approaches formalized tracking quality criteria are determined, methods of implementation of control systems and controllers taking into account these criteria are proposed. The part of the control signal responsible for taking into account geometry of the robot and avoiding collisions is defined via the force-moment vector representation. Results of simulation modeling prove the efficiency of the proposed approaches. A comparison of the proposed approaches is presented. Potential ways of more efficient use of these approaches are given.

Published: February 2021

Abstract
The relevance of the wide use of diagnostic equipment to assess and predict the condition of mining machineries of potash mines is presented in this paper. A promising method of diagnosing the base components of mining machineries (load frames and integral body), which involves an analysis of excited vibrations, is described. The equipment for its implementation is presented. An example of assessing the condition of steelwork of the body of a self-propelled loader bunker BPS-25 is given in the paper. The implementation of an analyzer of the synchronous vibrations «Kamerton» manufactured by Scientific-Production Enterprise «ROS» LLC (Perm) is instrumental in determining the presence of structural changes in a body’s steel of a loader bunker and in confining the position of fatigue cracks. It is shown that the wear of the sides and body’s floor pan of the loader bunker is not uniform. The limiting values of the loss of metal on the sides and floor pan are determined. In this paper, the search for faults was carried out in the entire metal volume of the examined unit. The evidence that the use of «Kamerton» equipment allows reducing material and time costs for the assessment of the mechanical condition of the structural steelwork of mining machineries is presented.
