Binary grey wolf optimizer with a novel population adaptation strategy for feature selection
Authors: Wang Dazhi , Ji Yanjing , Wang Hongfeng , Huang Min 
Published: May 2023

AbstractFeature selection is a fundamental pre‐processing step in machine learning that aims to reduce the dimensionality of a dataset by selecting the most effective features from the original features. This process is regarded as a combinatorial optimization problem, and the grey wolf optimizer (GWO), a novel meta‐heuristic algorithm, has gained popularity in feature selection due to its fast convergence speed and easy implementation. In this paper, an improved binary GWO algorithm incorporating a novel Population Adaptation strategy called PA‐BGWO is proposed. The PA‐BGWO takes into account the characteristics of the feature selection problem and designs three strategies. The proposed strategy includes an adaptive individual update procedure to enhance the exploitation ability and accelerate convergence speed, a head wolf fine‐tuned mechanism to exert the impact on each independent feature of the objective function, and a filter‐based method ReliefF for calculating feature weights with dynamically adjusted mutation probabilities based on the ranking features to effectively escape from local optima. Experimental comparisons with several state‐of‐the‐art feature selection methods on 15 classification problems demonstrate that the proposed approach can select a small feature subset with higher classification accuracy in most cases.
Optimal coordinated generation scheduling considering day‐ahead PV and wind power forecast uncertainty

Published: May 2023

AbstractEconomic operation and reliable supply‐demand balance are problems of paramount importance in power grids with a massive share of intermittent renewable energy sources (RESs) of great interest. This paper sought an optimal coordinated generation scheduling for day‐ahead power system operation considering RESs and energy storage units. Renewable power generation, particularly, wind and photovoltaic are uncontrollable, whereas can be predicted using forecasting models. Within the proposed framework, a hyperparameter‐optimized long short‐term memory (LSTM) regression model is employed to forecast the day‐ahead weather from the historical time‐series weather data. Eventually, an empirical formula is used to estimate the power conversion from the day‐ahead weather forecasts for a selected PV module and wind turbine. The objective of the scheduling framework is to keep a delicate supply‐demand balance at the lowest possible cost of generation while maintaining the prevailing generation and system constraints. A variance measure uncertainty handling‐based grey wolf optimizer (GWO) technique is used to find the optimal day‐ahead generation schedules and dispatches under RESs forecast uncertainty. The proposed generation scheduling framework is examined on the IEEE 6 and 30‐bus systems. In the studied scenarios, the coordinated operation of generators can decrease the total day‐ahead operating cost for the modified IEEE 6‐bus system by 2.57% compared to supplying electricity generation with conventional generators alone. Likewise, the total operating cost from the coordinated operation of all generation portfolios was reduced by 6.93% from the operating cost of generation during base case simulation (supply only from dispatchable thermal units) on the modified IEEE 30‐bus system. Moreover, the case studies show that coordinated generation scheduling can mitigate the RESs power variability problem, provide secure supply‐demand operation, and minimize the operating cost of electricity generation.

Published: May 2023

AbstractThe driver of a merging vehicle must account for both the lane‐changing risk and the remaining distance in the acceleration lane () during a merging decision‐making process. To investigate the impact of on merge decisions, a typical freeway merging section was selected and monitored with a millimetre radar and a high‐resolution digital camera, which were mounted on the guardrail in the gore area. More than 2000 merging vehicles were captured during the data collection process. The effects of the surrounding vehicles on the merging behaviour were analyzed, and a merging strategy model considering that was based on the random forest algorithm was constructed. The results show that the following vehicle in the target lane is the main factor that affects the merging behaviour of the merging vehicle. When the decision time window was set to 0.6 s, the proposed merging decision model could distinguish ‘Merge’ events and ‘Wait’ events with accuracies of 97.2% and 89.4%, respectively. The overall accuracy of the model was 94.9%, which was 3.9% higher than for a corresponding merging decision model that excluded influence. The proposed merging decision model can aid merging processes and give cues for human‐like merge decisions of automated vehicles.

AbstractExtra cation incorporations have been proved to enhance the properties of Cu2ZnSn(S, Se)4 materials, and help to obtain high‐efficiency solar cells. In this work, the authors study the influence of the extra tiny Mg2+ doping on the properties of Cu2ZnSn(S, Se)4 films. Through tuning the amount of Mg into the precursor solution, the crystallization, morphology, light absorption, and electrical properties all have been improved and can reach the optimum at 3% Mg‐doping, which is in favour of high‐performance CZTSSe devices. The authors’ finding also demonstrates Mg element can be regarded as the new candidate for extra cation incorporations.

Authors: Nötzli Manuela , Ameziane Yacine , Scheibel Markus 
Published: May 2023

Abstract
Case Two months after anterior shoulder dislocation and spontaneous reduction, a 41-year-old man presented movement-related shoulder pain and a functional deficit. An initially
missed osteochondral shearing injury of the humeral head with a Bankart lesion was diagnosed. Due to an extensive posteroinferior defect, an open reduction and internal fixation (ORIF) using
bioabsorbable chondral darts was performed. At the 1-year follow-up, magnetic resonance images showed a completely healed osteochondral fragment and the patient presented an unrestricted
shoulder function.
Conclusion Even in missed osteochondral shear injuries, ORIF with bioabsorbable implants can be associated with an excellent functional outcome and sufficient integrity of the
fragment. The absorbable implants are biocompatible, therefore the risk of revision surgery due to implant irritations is minimized.

Pulse TMS

Published: May 2023

Abstract
Introduction There is a need for novel anxiolytics with improved side
effect profiles compared to benzodiazepines. A promising candidate with
alternative pharmacodynamics is the translocator protein ligand, etifoxine.
Methods To get further insight into its mechanisms of action and side
effects compared to the benzodiazepine alprazolam, we performed a double-blind,
placebo-controlled, repeated-measures study in 36 healthy male subjects.
Participants were examined for trait anxiety and side effects and underwent
repeated transcranial magnetic stimulation (TMS) assessments, including motor
evoked potentials (MEP), short intracortical inhibition (SICI), intracortical
facilitation (ICF), and cortical silent period (CSP).
Results We observed attenuation of MEPs by alprazolam but not by
etifoxine. SICI was not significantly affected by alprazolam or etifoxine.
However, the response pattern indicated a lowered SICI threshold after the
administration of etifoxine and alprazolam compared to the placebo. ICF and CSP
were influenced by neither medication. Alprazolam led to higher sedation and
subjective impairment of concentration compared to etifoxine. Individual anxiety
trait scores did not affect TMS parameters.
Discussion This study indicated a favorable side effect profile of
etifoxine in healthy volunteers. Moreover, it revealed differential GABA-related
effects on neuromuscular function by means of TMS. The side effects and TMS
profile of etifoxine are compatible with the involvement of neurosteroidogenesis
and a predominant α3 subunit modulation compared to alprazolam.

AbstractEndoscopic submucosal dissection enables en bloc resection of large superficial colorectal neoplasms. However, it is sometimes challenging to retrieve a large resected specimen via the anus without sample fragmentation. A novel “bag-type” retrieval device has been developed to accomplish complete isolation and non-destructive delivery of oversized specimens. This single-center retrospective study was performed to demonstrate the efficacy of this device for large colorectal resected specimens. Among 17 patients, we identified 18 superficial colorectal lesions for which the use of a novel retrieval device (Endo Carry Large Type) was indicated at specimen delivery at a referral cancer institute from March 2021 to July 2022. The median (interquartile range) tumor size was 62.5 (52.0–79.5) mm. Retrieval of 17 (94%) of 18 resected specimens was performed using the Endo Carry Large Type, and 16 (89%) were successfully retrieved without sample fragmentation. The median (interquartile range) retrieval time was 4 (4–8) minutes, and no apparent adverse events were observed. The novel Endo Carry Large Type device can accomplish colorectal specimen retrieval safely and quickly without specimen damage and therefore may contribute to accurate pathological diagnosis.

Published: May 2023

AbstractTreatment of symptomatic osteoarthritis (OA) is often complicated by comorbidities, which put patients at potentially higher risks following operative interventions. Management of these comorbidities is usually separate from orthopaedic care, with patients invited to return to their orthopaedic surgeon once surgical risk factors are better controlled. However, this practice can lead to disjointed care, resulting in uncertainty, mistrust, unmanaged pain, and dissatisfaction for patients. Integrated care teams provide an effective option for coordinated comprehensive nonoperative and preoperative management of patients with knee OA and medical comorbidities. The objective of this article is to summarize the process for implementation of an integrated program to manage patients with symptomatic knee OA and the initial outcomes at our institution as an example of the effects of integrated patient management in orthopaedics. At the author's institution, an integrated program was implemented, successfully addressing the unmet need for coordinated care for patients with bone and joint health problems and medical comorbidities. Patients who completed the full program experienced significant improvements in both pain and function. Potential applications for knee surgeons considering implementing integrated care models could include pre- and postoperative management programs, nonoperative management program, and programs seeking to meet key metrics such as improved readmission rates, patient satisfaction, or value-based care. For effective program implementation, careful planning with convenient referral mechanisms, leadership buy-in, and patient-centered communication protocols are required.
Recommendations for metaverse governance based on technical standards
Authors: Yang Lijuan 
Published: May 2023

AbstractTechnical standards in digital technology can now be utilised to gather numerous digital sub-universes into the metaverse. However, how to create and implement guidance for the metaverse based on technical standards remains unexplored. This study investigated the theoretical framework and policy implications for future technical standards-based metaverse governance (TS-MG). The methodology entailed reviewing the available metaverse governance literature to establish both theoretical and case analyses of practices based on the economics of standards and the theory of networks. This study found that TS-MG encompasses the formulation, security, and compatibility of technical standards. TS-MG should enable the first-mover advantage of standards formulation for standard-setting organisations. It also includes phased governance policies that balance the compatibility and security of standards in the initial, growth, and mature stages of the metaverse. This study highlights the necessity of cooperation among governments, standard-setting organisations, and enterprises to (1) accelerate the development of systemised standards and (2) promote the effective supply of metaverse standards.

Authors: Guillemi Eliana Carolina , Farber Marisa Diana 
Published: May 2023

Abstract

Bovine babesiosis is caused by the intraerythrocytic protozoans
Babesia bovis
and
Babesia bigemina
in tropical and subtropical regions worldwide. The diagnosis of these tick-borne pathogens may represent a challenge due to the low parasitaemias usually found in
Babesia
persistent infections and also in acute cases. Additionally, the correct determination of the epidemiological status of a herd is a key point for further diagnostic interpretations. In this regard, in this work, we review the available diagnostic tools and suggest algorithms facing different epidemiological scenarios. Finally, we highlight the need for new sensitive and accurate point-of-care diagnostic tools for field babesiosis detection. The development of an international shared database for epidemiological data recompilation would be beneficial for the further design of diagnostic tools and vaccines.

Published: May 2023

Abstract
The stochastic resonance (SR) behavior for an underdamped bistable system with colored cross-correlated noise between multiplicative and additive noise is investigated. The stationary probability density is obtained under the condition of the detailed balance. The expressions for the signal-to-noise ratios (SNRs) for two initial states is deduced by applying two-state theory under the adiabatic condition. The analysis result indicates that the SR phenomenon takes place when the SNRs vary with the coupling strength and the correlation time of the cross-correlated noise. Double SR phenomenon occurs on SNRs’ curves with the increase of the strength of the additive noise. One resonance peak exists when the SNRs change with the damping coefficient and with the intensity of the multiplicative noise.

Authors: Zheng Hai-bo , Huang Jiang-tao , He Cheng-jun , Wu Bin , Gao Chao 
Published: May 2023

Abstract
In this paper, a novel thrust vector control method based on Coanda effect is proposed for conical surface. The effect of thrust vector control is studied by computation fluid dynamic (CFD) numerical simulation. When there is no side plate on both sides of Coanda surface, there are large vortex structures on both sides of nozzle wake, and the vector control cannot be realized. After adding the side plate, the comprehensive control of the pitch and yaw thrust vectors was realized. When the nozzle pressure ratio (NPR) is 2~2.4, the pitch and yaw vector angles decreased with the increase of NPR, and the maximum pitch vector angle is 8°. And the yaw vector angle is 8°.

Published: May 2023

Abstract
Composite materials are widely used in the design and manufacture of modern civil aircraft fuselage structures. Some large airliners already have full-size composite fuselages, which reduced the weight of the fuselage structure, but the problem of reinforcing the opening of the composite fuselage is also very important. In this paper, the design of medium and large scale open reinforcement structures in composite fuselages is focused. The force characteristics of passenger doors, cargo doors, landing gear hatch openings, and the reinforcement structure form are elaborated, and based on the current research status at home and abroad, the future development of composite fuselage opening reinforcement design is prospected.

Published: May 2023

Abstract
The equivalent parameters of hexagon aluminum honeycombs are work out with the theories of sandwich plates in this paper. The honeycomb sandwich plate reinforced by ring beam applied with static load is simulated by the finite element model of honeycomb sandwich plates, which is validated by static test. The research results show that the numerical calculation error of the honeycomb sandwich plate is less than 10% compared with test results, which is acceptable for an engineering project, and the mechanical behavior of the honeycomb sandwich plate can be described in detail. Thus, the method of equivalent honeycomb parameter is proved to be effective for the design and analysis of honeycomb sandwich plates. The influence of equivalent elasticity modulus and equivalent shear modulus to honeycomb sandwich plates can be reflected exactly from the results which are figured out with the equivalent theories of sandwich plates. The assembly clearance and assembly accuracy have a significant influence to the test results of honeycomb sandwich plates, which is obvious especially at a lower load level.

Combined with the UDF function of fluent, the boron particle ignition combustion program is self-programmed, the finite rate/eddy dissipation model is used as the gas combustion model, and the Realizable k-e turbulence model is used as the turbulence model. The numerical simulation was carried out under the cold flow state and the hot flow state, and the flow field distribution and parameters were obtained, and the mixing characteristics were analyzed. The error of simulation results and test results shows that that the numerical simulation results are in good agreement with the experimental results. By comparing the combustion efficiency and mixing degree, it is found that generally, When the mixing effect is not good, the combustion efficiency must be bad; When the mixing effect is good and the mixing degree is high, the combustion efficiency may be high.

Published: May 2023

Abstract
Aiming at the problem that the nonlinearity of the tracking state equation and the problem of strong noise in the measurement process in the process of tracking the target, a non-cooperative target tracking method in geostationary earth orbit based on adaptive memory attenuation UKF is proposed. Firstly, the relative motion model of the non-cooperative target is constructed, and the state equation and measurement equation are established. Use the memory attenuation adjustment factor to enhance the correction effect of the new measurement on the state estimation, improve the adaptability of the filtering method to nonlinearity and noise, and finally the relative motion trajectory of the space non-cooperative target is obtained. Finally, the standard UKF algorithm and improved UKF algorithm are applied to target tracking and compared by simulation. The deviation of the three coordinate axis components of the actual motion trajectory and the predicted trajectory of the space target is used as the evaluation index. The simulation results show that the filtering accuracy of the improved UKF algorithm is significantly improved, while taking into account the real-time performance of on-orbit tracking.

Published: May 2023

Abstract
A direct design method for direct abort trajectory based on the quasi-lambert problem is proposed. The re-entry constraint is analytically addressed via a quasi-lambert problem instead of variables iteration and optimization method in the past. Then a new parameter is introduced to determine the plane. The exact solution is determined by differential correction based on the initial solution. Numerical simulation is carried out to test the validity and efficiency of the method. The comparison with STK verifies its reliability. Additionally, the characteristics of direct abort trajectory and their application in the option strategy for different abort ways are studied. The flight time and abort point affect the abort trajectories’ velocity increment and the latitude of the landing area.
