Published: March 2023

AbstractChemical investigation of the endophyte Pseudofusicoccum stromaticum CMRP4328 isolated from the medicinal plant Stryphnodendron adstringens yielded ten compounds, including
two new dihydrochromones, paecilins Q (1) and R (2). The antifungal activity of the isolated metabolites was assessed against an important citrus pathogen, Phyllosticta
citricarpa. Cytochalasin H (6) (78.3%), phomoxanthone A (3) (70.2%), phomoxanthone B (4) (63.1%), and paecilin Q (1) (50.5%) decreased in vitro the
number of pycnidia produced by P. citricarpa, which are responsible for the disease dissemination in orchards. In addition, compounds 3 and 6 inhibited the development
of citrus black spot symptoms in citrus fruits. Cytochalasin H (6) and one of the new compounds, paecilin Q (1), appear particularly promising, as they showed strong activity
against this citrus pathogen, and low or no cytotoxic activity. The strain CMRP4328 of P. stromaticum and its metabolites deserve further investigation for the control of citrus black
spot disease.

Abstract
Rhododendron principis leaves have been used as “Dama”, a Traditional Tibetan Medicine for treating inflammatory diseases. R. principis crude polysaccharides with
anticomplementary activity demonstrated promising anti-inflammatory effects on acute lung injury induced by lipopolysaccharide. R. principis crude polysaccharides significantly
decreased the levels of TNF-α and interleukin-6 in both serum and blood and bronchoalveolar lavage fluid in lipopolysaccharide-induced acute lung injury mice by intragastric
administration (100 mg/kg). A heteropolysaccharide, ZNDHP, was obtained from R. principis crude polysaccharides with successive anticomplementary activity-guided separation. ZNDHP was
characterized as a branched neutral polysaccharide with a backbone composed of → 2)-β-Glcp-(1→, → 2,6)-α-Glcp-(1→, → 6,3)-β-Galp-(1→,
→ 2,6)-α-Galp-(1→, → 6,2)-β-Glcp-(1→, → 4)-α-Glcp-(1→, → 5)-β-Araf-(1→, → 3,5)-α-Araf-(1→, and
→ 4,6)-β-Manp-(1→, and the backbone structure was further confirmed by partial acid hydrolysis. In addition to anticomplementary and antioxidant activities, ZNDHP exhibited
potent anti-inflammatory activity by significantly inhibiting the secretion of nitric oxide, TNF-α, interleukin-6, and interleukin-1β of lipopolysaccharide-treated RAW 264.7
cells. However, all of these activities decreased greatly after partially hydrolyzing, indicating the importance of the multibranched structure for its bioactivity. Therefore, ZNDHP might be
an important component of R. principis for treating inflammation.

Published: March 2023

Abstract
Objectives The aim of this prospective study was to compare the healing of periapical bone between smokers and nonsmokers after root canal therapy. The effects of duration and intensity of smoking on the healing rate of apical periodontitis were analyzed.
Materials and Methods Fifty-five smokers were included in this study. The control group consisted of healthy nonsmokers who matched the smoker group in age and sex. Only teeth with a favorable periodontal prognosis and adequate coronal restoration were included in the study. The periapical status of treated teeth was assessed using the periapical index system at follow-ups after 6 and 12 months.
Statistical Analysis The chi-squared test and Mann–Whitney U test were used to assess the changes in periapical index score at baseline and in subsequent time intervals between the two groups examining dichotomized and ordinal data, respectively. Multivariate logistic regression analysis was used to test the association of independent variables age, gender, tooth type, arch type, and smoking index with the outcome variable. The outcome variable was set as the presence versus absence of apical periodontitis.
Results The analysis at 12-month follow-up revealed a significantly higher healing rate in control group than in smokers (90.9 vs. 58.2; χ2 = 13.846; p < 0.001). Smokers had significantly higher periapical index scores than the control group (p = 0.024). The multivariate logistic regression analysis demonstrated that an increase in the value of the smoking index significantly increases the risk of apical periodontitis persistence (odds ratio [OR] =7.66; 95% confidence interval [CI]: 2.51–23.28; p < 0.001) for smoking index < 400 and (OR = 9.65; 95% CI: 1.45–64.14; p = 0.019) for smoking index 400 to 799.
Conclusion The results from this study show a lower rate of apical periodontitis healing in a group of smokers at 1-year follow-up. Delayed periapical healing seems to be associated with the cigarette smoking exposure.

Published: March 2023

AbstractThe problem of gender bias is highly prevalent and well known. In this paper, we have analysed the portrayal of gender roles in English movies, a medium that effectively influences society in shaping people’s beliefs and opinions. First, we gathered scripts of films from different genres and derived sentiments and emotions using natural language processing techniques. Afterwards, we converted the scripts into embeddings, i.e., a way of representing text in the form of vectors. With a thorough investigation, we found specific patterns in male and female characters’ personality traits in movies that align with societal stereotypes. Furthermore, we used mathematical and machine learning techniques and found some biases wherein men are shown to be more dominant and envious than women, whereas women have more joyful roles in movies. In our work, we introduce, to the best of our knowledge, a novel technique to convert dialogues into an array of emotions by combining it with Plutchik’s wheel of emotions. Our study aims to encourage reflections on gender equality in the domain of film and facilitate other researchers in analysing movies automatically instead of using manual approaches.
Can temporal clauses be insubordinate?
Authors: Couper-Kuhlen Elizabeth , Thompson Sandra A. 
Published: March 2023

AbstractIn this paper we aim to determine whether temporal clauses can be shown to be insubordinate in everyday American English interaction. In order to investigate grammatical insubordination in conversation, we operationalize the notion of ‘insubordination’ as a specific practice for designing a turn-at-talk and implementing a social action. That is, we treat as ‘insubordinate’ a clause with a grammatically subordinate form that (a) is freestanding, that is, forms a prosodic unit of its own, (b) implements a discrete social action in its sequential context, and (c) has an independent interpretation, that is, is interpretable and actionable in the absence of a main clause. We then examine five different types of freestanding temporal clauses in conversation which might be considered candidate insubordinate uses. Our data show that in some cases both criteria (b) and (c) are lacking, while in others it is criterion (c) that is absent. In none of these cases are all three criteria satisfied at once. We conclude that temporal clauses do not exhibit insubordination in English conversation as do other adverbial clauses such as those with ’if’.
Computational modeling of a generative grammar for clitic order in River Plate Spanish
Authors: Koza Walter , Mare María 
Published: March 2023

AbstractThe order of clitics (CLs) in Romance languages has been studied in depth by many scholars since Perlmutter’s first approach. This author points out that person and case features impose a filter that results in the following pattern in Spanish: Se- II- I- IIIdat- IIIacc. This pattern has been revisited because it is not restrictive enough: it gives rise to impossible sequences. In this context, the goal of this work is to define a pattern of morphosyntactic features for River Plate Spanish clitics, and an ordering pattern, with the purpose of developing a computational model for an automatic analysis of this phenomenon. This kind of analysis is justified because the algorithm output shows the degree of success of the descriptive proposal. To this end, we use NooJ, a linguistic development environment that has diverse tools. The computational modeling involves two stages: (i) the creation of an electronic dictionary and (ii) the creation of a computational grammar. The algorithm developed can generate all correct sentences conformed by Nominative Pronoun + CL + CL + Verb, Non-Finite Verb-CL-CL and Imperative Verb-CL-CL, and it can recognize these kinds of expressions in written text assigning the correct semantic labels. With these results, we conclude that our descriptive proposal is adequate for the analysis of sequences of clitics in River Plate Spanish.

Abstract
In this contribution, we overview a recent theoretical work [1] where a sound statistical and systematic analysis based on nuclear Energy Density Functionals of the parity violating asymmetry and dipole polarizability in 208Pb has been presented. Based on our results, we predict a neutron skin thickness in 208Pb which barely overlaps the lower-edge of the estimation presented in [2] and is consistent with much of the previous work.

Abstract
An aircraft is unstable in longitudinal motion, the variation of aerodynamic derivatives and center-of-gravity position caused by altitude, speed, and fuel have a great impact on the control and stability of the aircraft. By using the Linear Matrix Inequality (LMI) approach, the longitudinal static stability of the aircraft is compensated. In addition, the pitch attitude control system is designed, and multi-objective control, including pole assignment and controlled variable constraints, is achieved during the designing process. As a result, the robustness of the system is also achieved. Finally, the simulation results of the pitch attitude control system show that this design approach is feasible.

Authors: Zhang Zhenzhou , Qiu Qunxian , Wu Yuhang 
Published: March 2023

Abstract
In this paper, an Active Disturbance Rejection Controller (ADRC) based on an improved Particle Swarm Optimization (PSO) algorithm is proposed. The ADRC is conducive to addressing the situation that the electromechanical servo system is loaded with a large inertia barrel and is significantly affected by disturbances when working at high speed and precision. It can not only improve the anti-disturbance performance of the system but also ensure the dynamic performance of the system. Firstly, a simplified mathematical model of the electromechanical servo system is established and the non-linear factors of the system are analyzed. Secondly, the ADRC is designed and the parameters are optimized by utilizing the improved PSO algorithm. Finally, the control effect of the proposed method is simulated and analyzed. The simulation consequences demonstrate that compared with the traditional PID control, the proposed method can significantly increase the anti-disturbance capability of the servo system, and guarantee the accuracy index of the system.

Published: March 2023

Abstract
With the rapid development of UAV-related directions, intelligent UAVs have been applied to various industries of modern production and life. One particularly popular application is “delivery UAV.” By giving commands to the UAV, It can accomplish complex tasks such as target point flight and cargo delivery autonomously. On the one hand, human resources can be liberated; on the other hand, fully automated operations can greatly improve production efficiency. Our team used STM32 produced by Stmicroelectronics as the main control of the UAV, OpenMV from SingTown Technology, and K210 from Canaan Technology as the vision processor to design and develop a delivery quadrotor. The UAV uses an optical flow module to achieve hover and cruise and is equipped with a laser ranging module to assist the UAV in obtaining height. K210 and OpenMV are used for target detection, and the Hanging basket can be raised and lowered to simulate “delivery.” The UAV can realize automatic cruise, target-point “delivery,” target detection, obstacle avoidance, and many other functions.

Abstract
Satellite communication technology can solve the signal covering issues in special areas, such as deserts and oceans, which is difficult to handle with in traditional terrestrial wireless networks. Mobile edge computing (EMC) is crucial to help satellite communication to improve latency and energy efficiency performance. In this paper, we model a satellite constellation edge computing architecture with three layers and propose a task offloading deployment approach to balance the computation task. Simulation results show that the proposed algorithm can greatly reduce the execution delay of missions, improve the utilization of satellite resources, and increase the mission success rate compared with the existing strategies.

Authors: Gao Na , WeidongYang  
Published: March 2023

Abstract
In order to improve the quality of low-speed and high angle of attack test data and master the law of support interference, a numerical simulation study of support interference was carried out for a wind tunnel tensioning tail brace system. The results show that the impact of the beam of wire-assistant sting support on longitudinal aerodynamics characteristics of aircraft is small, and the “E” sting greatly affects longitudinal aerodynamics characteristics at a high angle of attack. The yawing moment coefficients decrease, and rolling moment coefficients increase at the angle of attack from 0°to 20° with the existence of wire-assistant sting support. With the increase of side slip angle, the interference becomes bigger, then becomes smaller, and 30°is the biggest.

Published: March 2023

Abstract
Power monitoring network attack detection and defense can only target known types of attacks. This simple defense detection method cannot effectively defend against complex network attacks, so it is necessary to adopt the tracing technology of actively searching for the source of attacks. This paper discusses the electric power monitoring and control network attack, attack tracing method, and genetic algorithm. Based on applications traceability method for electric power monitoring and control network attack behavior of power monitoring data collection network and the genetic algorithm, parameter settings were described. Furthermore, the process of tracing the attack behavior of the power monitoring network based on multi-level data association and genetic algorithm is designed and discussed. The success rate of tracing the attack behavior of the power monitoring network is analyzed by four operators in the genetic algorithm. The experimental data show that the success rate of the four operators in tracing the source of the three kinds of attacks in the power monitoring network is more than 97% on average. Therefore, the method of tracing the attack behavior of the power monitoring network based on the genetic algorithm has high practical value.
