Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the short-term activity of host stars.
Aims. The HARPS-N red Dwarf Exoplanet Survey programme is a long-term project at the Telescopio Nazionale Galileo aimed at monitoring nearby, early-type, M dwarfs, using the HARPS-N spectrograph to search for small, rocky planets.
Methods. A total of 174 HARPS-N spectroscopic observations of the M0.5V-type star GJ 9689 taken over the past seven years have been analysed. We combined these data with photometric measurements to disentangle signals related to the stellar activity of the star from possible Keplerian signals in the radial velocity data. We ran an MCMC analysis, applying Gaussian process regression techniques to model the signals present in the data.
Results. We identify two periodic signals in the radial velocity time series, with periods of 18.27 and 39.31 d. The analysis of the activity indexes, photometric data, and wavelength dependency of the signals reveals that the 39.31 d signal corresponds to the stellar rotation period. On the other hand, the 18.27 d signal shows no relation to any activity proxy or the first harmonic of the rotation period. We, therefore, identify it as a genuine Keplerian signal. The best-fit model describing the newly found planet, GJ 9689 b, corresponds to an orbital period of Pb = 18.27 ± 0.01 d and a minimum mass of MP sini = 9.65 ± 1.41 M⊕.

Magnetic field amplification to gigagauss scale via hydrodynamic flows and dynamos driven by femtosecond lasers
Authors: Jiang K , Pukhov A , Zhou C T 
Published: May 2021

Abstract
Reaching gigagauss magnetic fields opens new horizons both in atomic and plasma physics. At these magnetic field strengths, the electron cyclotron energy ℏω
c becomes comparable to the atomic binding energy (the Rydberg), and the cyclotron frequency ω
c approaches the plasma frequency at solid state densities that significantly modifies optical properties of the target. The generation of such strong quasistatic magnetic fields in laboratory remains a challenge. Using supercomputer simulations, we demonstrate how it can be achieved all-optically by irradiating a micro-channel target by a circularly polarized relativistic femtosecond laser. The laser pulse drives a strong electron vortex along the channel wall, inducing a megagauss longitudinal magnetic field in the channel by the Inverse Faraday Effect. This seed field is then amplified up to a gigagauss level and maintained on a sub-picosecond time scale by the synergistic effect of hydrodynamic flows and dynamos. Our scheme sets a possible platform for producing long living extreme magnetic fields in laboratories using readily available lasers. The concept might also be relevant for applications such as magneto-inertial fusion.

Published: May 2021

Abstract
DE algorithm method for Solving the inverse kinematics is a fundamental problem in the robotics field especially in controlling industrial robots to move following a pre-defined trajectory. In this paper, we proposed to use a meta-heuristic optimization algorithm, namely Differential Evolution (DE), to solve the Inverse Kinematic (IK) problem for a five-degree-of-freedom (DOF) articulated robot. By considering joints’ angles as continuous variables, the process of solving the Inverse Kinematic problem for the robot with the optimal algorithm has been significantly improved in terms of accuracy, execution time, standard deviation (STD) and the number of iterations needed as well. The algorithm has been applied to solve the Inverse Kinematic problem on the 5-Degree of Freedom 5R robot model. The simulation results for three case studies showed that our method can solve the inverse kinematics problem efficiently not only for minimum errors but also for smooth value of the joints’ variables.

Published: May 2021

Abstract
This paper presents a mechanical design and motion-control system of a Wall-Climbing Robot (WCR) which can move on the silo’s surface for cleaning purposes. One of the most challenges with this type of robot that the researchers confront is how to keep the robot moving steadily on the wall with the most optimal approach. In this study, a new mechanical design of the Wall-Climbing robot using the Vacuum principle and wireless control technology were proposed. This version of the robot enhances the ability of its movement on the silo’s wall and optimizes control system. In detail, the Minimum Required Adhesion Force (FMRA) is calculated to be balanced with gravity and its torque. Moreover, a Wireless Control System (WCS) is designed to drive the Robot remotely. The optimal control trajectory and velocities are given based on theory calculations and comparisons.

Published: May 2021

Abstract
Mariculture has a profound potential to sustainably meet the escalating demands for food and livelihoods. However, the socioeconomic impacts of small-scale aquaculture (SSA) are poorly understood, particularly for marine SSA in China, a leading global producer of aquaculture products. Using detailed household surveys, we comprehensively evaluated profitability, income inequality, and subjective well-being of marine SSA households in a representative coastal city in Southeastern China. Our results show that mariculture practices increased income but exacerbated income inequality in animal mariculture households (AMHs) and seaweed mariculture households (SMHs). Earnings from AMHs (544 549 yuan) were four times higher than those of SMHs (141 172 yuan) although AMHs were twice as likely to make a loss (27.4% versus 12.5%). Natural capital (11.37%) and the cultured variety (12.40%) were the main contributors to mariculture income inequality for AMHs, while manufactured capital (27.59%) and previous mariculture experience (8.59%) were significant for SMHs. The well-being of AMHs was better than that of SMHs. Our results suggest that secure access to sea areas, provision of financial options to mariculture smallholders, as well as diversification in mariculture type and variety could promote the socioeconomic sustainability of mariculture development.

Several research groups have already reported their ST delignification. However, there is still needs to find a suitable delignification technique for improving recovery of cellulose and eliminate lignin and hemicellulose from a complex structure of ST. One of the methods for delignification is used alkaline with a high temperature. Hence, the research aim is to investigate the effect of alkaline-autoclaving delignification method on chemical component changes of ST. The different sample of ST including washing process and microwave-assisted maleic acid pretreatment prior to the delignification process with 2% NaOH combine with autoclaving in 121°C temperature was used in this study compare with the initial sample. The chemical composition changes in pretreated solid fractions and reducing sugar in pretreated liquid were analyzed. The functional properties were also analyzed using Fourier Transform Infrared (FTIR). The results showed that microwave-assisted maleic acid pretreatment before delignification was the effective treatment in this study to eliminate lignin (88.11%) and hemicellulose (44.07%) and cellulose recovery (78.40%) than that other treatment. Besides, the reducing sugar obtained from microwave-assisted maleic acid pretreatment 3.2 times and 3.6 times higher than that initial biomass and washing treatment, respectively. The FTIR spectra showed that washing treatment affects increasing absorbance of hydroxyl group while the maleic acid pretreatment was also increasing absorbance of carbonyl and the aromatic group that is a feature of lignin compound.

Abstract
The effect of botanical pesticides as an insect pest control agent has been proven in several studies. Despite capable of controlling pests, botanical pesticides have not been reported to promote plant growth. One technique for making botanical pesticides served in dual function is to combine them with beneficial microbes. This study was aimed to determine the compatibility of 3 isolates of Bacillus sp. and 3 isolates of Pseudomonas sp. against botanical pesticides. The botanical pesticides were made from a mixture of Ageratum conyzoides, Aglaia odorata, and Azadirachta indica leaves. The solvent used 96% ethanol, and the process of making botanical pesticides was performed using a rotary evaporator at 45˚C. The compatibility test was performed in vitro by dropping 10 µl of botanical pesticides on the bacterial culture. Tests were carried out using various concentrations, namely 0%, 25%, 50%, 75%, and 100%. The test results showed that Bacillus sp. A and Pseudomonas sp. E strain were compatible on all assay concentrations. Bacillus sp. A and Pseudomonas sp. D and Pseudomonas sp. E were compatible with the concentrations of 0 to 75%. Furthermore, Bacillus sp. B, Bacillus sp. C, and Pseudomonas sp. F were compatible with the assay concentrations of 0 to 50%.
Modeling and analysis of the compressor for the closed cycle system on anti-surge process
Authors: Sun Y R , Yao L X , Jin X , Sun Y Y , Tao C 
Published: May 2021

Abstract
In order to study the interaction mechanism of the pipe network, the compressor and the control system in the process of the anti-surge regulation, the simulation model of the overall Closed Cycle System (CCS) is established in this paper. By comparing the simulation results with the target values at the Design Operation and the Maximum Mach Operation, the calculation deviation is less than 1%, which verifies the accuracy of the model. At the Maximum Mach Operation, the analysis of the CCS during the quasi steady process and the dynamic process is carried out respectively. According to the result of quasi steady state analysis, the effectiveness of the designed anti-surge circuit during the normal operating process of the CCS is verified. By opening the Anti-Surge Valve, additional 38.5% surge margin is provided. And the surge margin at the simulation process would be slightly higher than the design value for the variation of the inlet condition from the different operations. Through the dynamic analysis, the changes of the different performance parameters are studied in the process of sudden blockage in the pipe network, and during this process the compressor surge could be induced easily due to the sharp decline of the inlet pressure. To ensure the safety of the compressor during the acceleration and deceleration process, the moving trajectory of the operation point on the Compressor Characteristic Map should be studied by considering the effect of the resistance characteristics of the CCS pipe network. In addition, the anti-surge system should have a high response frequency to deal with the sudden blockage.
