Authors: Simmons Benjamin M. , Gresham James L. , Woolsey Craig A.
Published: June 2023

This paper provides an overview of flight-test system identification methods applied in the Virginia Tech Nonlinear Systems Laboratory that focus on modeling small, inexpensive, fixed-wing aircraft controlled by a ground-based pilot. The general aircraft system identification approach is outlined with details provided on the flight-test facilities, experiment design methods, instrumentation systems, flight-test operations, data processing techniques, and model identification methods enabling small aircraft flight dynamics model development. Specific small aircraft system identification challenges are overcome, including low-cost control surface servo-actuators and instrumentation systems, as well as a greater sensitivity to atmospheric disturbances and limited piloting cues. Four recent system identification research advancements using the general system identification process are featured, including application of uncorrelated pilot inputs for remotely piloted aircraft, aero-propulsive model development for propeller aircraft, spin aerodynamic model development, and nonlinear dynamic modeling without mass properties information. Although this paper provides a summary of several research efforts, the core system identification approach is presented with sufficient detail to allow the methods to be readily adapted to other research efforts leveraging small, low-cost aircraft.
Impact Angle Control Guidance Considering Seeker’s Field-of-View Limit Based on Reinforcement Learning
Authors: Lee Sangmin , Lee Youngjun , Kim Youdan , Han Yongsu , Kwon Hyuckhoon , Hong Daseon
Published: June 2023

This study proposes a computational impact angle control guidance law against a stationary target considering the seeker’s field-of-view (FOV) limit based on a deep reinforcement learning (RL) method. The proposed guidance law generates the acceleration command as a sum of the baseline command and bias command where the bias command is learned through a sequence of learning stages. Each stage trains an RL agent that addresses the impact angle and the FOV limit constraint individually. This approach is favorable in that the succeeding training process tends to preserve the functionality of the guidance law attained in the previous stage. In addition, the proposed method can be easily extended to a missile model with additional elements such as rotational dynamics without the necessity of modifying the algorithm. The proximal policy optimization algorithm is used for training the RL agents. Numerical simulation is carried out under various conditions to analyze the performance and the effects of a design parameter on the performance. The learning strategy proposed in this study provides a way to apply a data-driven method to developing a guidance law under multiple design objectives and more realistic missile models.

Published: June 2023

The entry phase constitutes a design driver for aerospace systems that include such a critical step. This phase is characterized by hypersonic flows encompassing multiscale phenomena that require advanced modeling capabilities. However, because high-fidelity simulations are often computationally prohibitive, simplified models are needed in multidisciplinary analyses requiring fast predictions. This work proposes data-driven surrogate models to predict the flow and mixture properties along the stagnation streamline of hypersonic flows past spherical objects. Surrogate models are designed to predict the velocity, pressure, temperature, density, and air composition as functions of the object’s radius, velocity, reentry altitude, and surface temperature. These models are trained with data produced by numerical simulation of the quasi-one-dimensional Navier–Stokes formulation and a selected Earth atmospheric model. Physics-constrained parametric functions are constructed for each flow variable of interest, and artificial neural networks are used to map the model parameters to the model’s inputs. Surrogate models were also developed to predict surface quantities of interest for the case of nonreacting or ablative carbon-based surfaces, providing alternatives to semiempirical correlations. A validation study is presented for all the developed models, and their predictive capabilities are showcased along selected reentry trajectories of space debris from low Earth orbits.

Published: June 2023

Mesh manipulation is central to computational fluid dynamics. However, creating appropriate computational meshes often involves substantial manual intervention that has to be repeated each time the target shape changes. To address this problem, we propose an autodecoder-based latent representation approach. Human prior knowledge is embedded into learned geometric patterns, which eliminates the need for further handcrafting. Furthermore, the resulting computational meshes are differentiable with respect to the model parameters, which makes it suitable for inclusion in end-to-end trainable pipelines. We apply the model on two-dimensional airfoils to demonstrate its ability to handle various tasks.

Synthesis and Reactivity of Alkali Metal Hydrido-Magnesiate Complexes which Exhibit Group 1 Metal Counter-Cation Specific Stability
Authors: Evans Matthew , Jones Cameron
Published: June 2023

Reactions of the series of alkali metal amides M(HMDS) (M = Li – Cs; HMDS = [N(SiMe3)2]-) with the neutral magnesium(II) hydride compound [Mg(BDIDipp)(μ-H)]2 (BDIDipp = [CH{C(Me)NDipp}2]-, Dipp = 2,6-iPr2-C6H3) have been carried out. When M = Li or Na the reactions yielded Mg(BDIDipp)(HMDS) and MH as the primary products. In the sodium amide reaction [Na2(HMDS)][{Mg(BDIDipp)}2(H)3] was obtained as a low-yield by-product. When M = K–Cs, the reactions gave the group 1 metal hydrido-magnesiates M2[Mg(BDIDipp)(HMDS)(H)]2·(benzene)n (n = 0 or 1), the thermal stability of which increases with increasing molecular weight of the alkali metal involved. Reactions of Cs2[Mg(BDIDipp)(HMDS)(H)]2·(benzene) with 18-crown-6 and CO gave the first monomeric alkali metal hydrido-magnesiate [Cs(18-crown-6)][Mg(BDIDipp)(HMDS)(H)] and the ethenediolate complex Cs2[{Mg(BDIDipp)(HMDS)}2(-C2H2O2)], respectively. The new synthetic route to alkali metal hydrido-magnesiates described herein may facilitate further reactivity studies of this rare compound class.

Published: June 2023

Diabetes mellitus remains a major global health burden and great attention is directed at natural therapeutics. This systematic review aimed to evaluate the potential of flavonoids as antidiabetic agents through their ability to inhibit α-amylase and α-glucosidase, two key starch digestive enzymes. Six scientific databases were queried up until August 21, 2022, for in vitro studies reporting the IC50 results of purified flavonoids on α-amylase or α-glucosidase, along with the respective data of acarbose control. A total of 339 articles were assessed as eligible and subjected to the data extraction process, resulting in 1643 retrieved flavonoid structures. Chemical structures were then rigorously standardized and curated to 974 unique compounds, in which 177 flavonoids showed both inhibitions against α-amylase and α-glucosidase. Quality assessment was conducted following a modified CONSORT checklist. The structure-activity relationships revealed that a double bond C2=C3 and a keto group C4=O is essential for simultaneous inhibition. The hydroxyl group at C3 is favourable for α-glucosidase inhibition but detrimental to the effect against α-amylase. Further notable features which affect α-glucosidase and α-amylase inhibition were also discussed. Several limitations were considered, including the inconsistency among included studies, language restriction, and the contemporaneity of the review. In conclusion, the systematic review has summarized some crucial findings in the investigation of flavonoids as dual-target inhibitors against α-glucosidase and α-amylase and proposed several orientations for future research.
Electronegativity equilibration based on symmetry
Authors: zeng weicheng
Published: June 2023

A simple rule is deduced, providing new insight into the role of symmetry in determining electronegativity equilibrium. A bell-shaped symmetric graph has been found that interrelates atomic stress and electronegativity in heteronuclear diatomic molecules. This model displays a perspective in which the electronegativity of bonded atoms is equilibrium and the stresses between atoms is equal. The uniqueness of this model is that it can calculate the electronegativity of atoms in different molecules.

Published: June 2023

Organic iodine(III) compounds represent the most widely used hypervalent halogen compounds in organic synthesis, where they usually perform the role of an oxidant or electrophile to functionalize electron-rich or nucleophilic organic compounds. In contrast to this typical reaction mode and the nature of organohalogen compounds in general, we discovered a novel reactivity of organoiodine(III) compounds that behave as organometallic-like nucleophiles toward arynes. Possessing diverse transferable ligands and being supported by a cyclic spectator ligand, the organoiodine(III) compounds undergo addition across the electrophilic C–C triple bond of arynes while retaining the trivalency of the iodine center. This carboiodanation reaction can forge a variety of aryl–alkynyl, aryl–alkenyl, and aryl–(hetero)aryl bonds along with the concurrent formation of an aryl–iodine(III) bond under mild conditions. The newly formed aryl–iodine(III) bond serves as a versatile linchpin for downstream transformations, particularly as an electrophilic reaction site. The amphoteric nature of the iodine(III) group as a metalloid and a leaving group in this synthetic sequence enables the flexible and expedient synthesis of extended π-conjugated molecules and privileged biarylphosphine ligands, where all the iodine(III)-containing compounds can be handled as air- and thermally stable materials.

Authors: Budiawan Raden Yusuf Sidiq , Utomo Vradyna Ashary
Published: June 2023

This research aims to describe how CNN Indonesia, Tribunnews.com, and Kompas.com structure their coverage of the Taliban in Indonesia. This study is descriptive-qualitative in nature. Data were collected using the documentation method through the note-taking technique, namely by listening to reports about the Taliban on the CNN Indonesia, Tribunnews.com, and Kompas.com websites, then recording the findings and analyzing them by adopting the Pan and Kosicki analysis model. The results of the study show that those three online media arrange news information in an inverted pyramid structure with an orderly and complete scheme. The comparison of those media can be seen in the theme of the news that is presented about the Taliban, including the impact or consequences of the rule of the Taliban in Afghanistan, the policies or system of the Taliban government in Afghanistan, and the efforts made by the Taliban to have their government recognized immediately. The framing results from those media eventually resulted in a different direction of view, including CNN Indonesia wanting to give a negative view of the Taliban, Tribunnews.com indirectly directing that the Taliban is still a radical group with cruel rules, and Kompas.com being a media that runs its media with balance.Abstrak     Penelitian ini mendeskripsikan bagaimana CNN Indonesia, Tribunnews.com, dan Kompas.com menyusun liputan mereka tentang Taliban di Indonesia. Penelitian ini berjenis kualitatif deskriptif. Data dikumpulkan dengan menggunakan metode dokumentasi melalui teknik simak catat, yaitu mendengarkan laporan tentang Taliban di laman CNN Indonesia, Tribunnews.com, dan Kompas.com, kemudian mencatat temuan data dan dianalisis dengan mengadopsi model analisis Pan dan Kosicki. Hasil penelitian menunjukkan bahwa ketiga media daring tersebut menyusun informasi berita dengan struktur piramida terbalik dengan skema yang disusun secara teratur dan lengkap. Perbandingan ketiga media daring tersebut tampak pada tema pemberitaan yang dibawakan mengenai Taliban, di antaranya dampak atau akibat dari kekuasaan Taliban di Afghanistan, kebijakan atau sistem pemerintahan Taliban di Afghanistan dan upaya yang dilakukan Taliban agar pemerintahannya segera diakui. Hasil framing dari ketiga media massa itu pun akhirnya menghasilkan perbedaan arah pandangan. CNN Indonesia ingin memberi pandangan negatif terhadap Taliban, Tribunnews.com secara tidak langsung mengarahkan bahwa Taliban masih merupakan kelompok radikal dengan peraturannya yang kejam dan Kompas.com menjadi media yang menjalankan medianya dengan seimbang.
Erotism and the Translation of the Poetry "Di Antara Kita" by Ajip Rosidi and "Nyanyian Duniawi" by W.S. Rendra
Authors: Sutikno Eka Ugi
Published: June 2023

Undoubtedly W. S. Rendra's poem “Nyanyian Dunia” can be brought closer to semantics, worldviews, and humanities values. However, the three things above become a contrast when faced with research that focuses on eroticism and Newmark's method of translation. Mainly “Di Antara Kita” by Ajip Rosidi, which has not yet been analyzed. This study aims to explain how erotic texts are presented to create aesthetics in poetry writing and how the three poems above are translated through the perspective of the Newmark translation method. The method used in this article is qualitative. The results show that “Di Antara Kita” on ‘Between Us’ and “Nyanyian Duniawi” on ‘A Worldly Song’, translated by Harry Aveling above, is dominated by the free translation method, and the diction contained in the source text and translation cannot be classified into in pornographic texts. The conclusion is that eroticism in the two poems above is confronted with the choice of diction, so the poems “Di Antara Kita” and “Nyanyian Duniawi” are not included in pornography, which is so verbal and obscene. Also, the eroticism in the two poems above reflects the desire of the two subjects who want each other’s love and bodies. AbstrakTidak diragukan lagi, puisi W. S. Rendra yang berjudul “Nyanyian Dunia” memiliki nilai semantik, pandangan dunia, dan humaniora yang kental. Akan tetapi, ketiga hal itu menjadi kontras ketika dihadapkan pada penelitian yang menitikberatkan pada erotisme dan metode penerjemahan ala Newmark. Terlebih “Di Antara Kita” karya Ajip Rosidi yang belum pernah dianalisis. Tujuan kajian ini ialah menjelaskan bagaimana teks erotisme dihadirkan untuk menciptakan estetika dalam penulisan puisi dan bagaimana ketiga puisi di atas diterjemahkan melalui perspektif metode penerjemahan Newmark. Penelitian ini menggunakan metode kualitatif. Analisis menunjukkan bahwa “Antara Kita” atas Between Us dan “Nyanyian Duniawi” atas A Worldly Song yang diterjemahkan oleh Harry Aveling didominasi oleh metode free translation dan diksi yang terdapat di dalam teks sumber dan terjemahan tidak dapat digolongkan ke dalam teks pornografi. Simpulan yang diperoleh adalah erotisme di kedua puisi itu dihadapkan pada pemilihan diksi sehingga tidak termasuk ke dalam pornografi yang begitu verbal dan cabul. Erotisme di kedua puisi di atas mencerminkan adanya hasrat dari dua subjek yang saling menginginkan cinta dan tubuh mereka.

Published: June 2023

Teacher self-efficacy (TSE) in drug education is critical because it is linked to teachers’ beliefs and ability to deliver learning material about drug abuse to students. There is scant literature about TSE in drug education. This might be due to the lack of valid instruments measuring TSE in drug education. This study aimed to validate and test the TSE Scale among secondary school teachers in drug education. The TSE Scale was adapted from the instrument of teacher efficacy by Tschannen-Moran and Hoy (2001). One hundred and thirteen public secondary school teachers in Johor, Malaysia were involved in this quantitative study. Cronbach’s alpha was used to examine the internal consistency and factor analysis through factor loading to confirm the items in each construct. The results reveal that the scale has internal consistency, with a Cronbach alpha value greater than .7. Furthermore, the factor loading results confirm the structure of the instrument, where each item had a factor loading greater than .5 and was loaded in each construct. Therefore, the TSE Scale is a valid tool to measure secondary school teacher self-efficacy in drug education. The instrument can be used in studies related to drug prevention activities in secondary schools.

Authors: Beyazgül Burcu , Cindoğlu Çiğdem , Koruk İbrahim
Published: June 2023

Background/Aim: During the COVID-19 pandemic, many health care workers had to perform jobs that were not in their area of expertise. That the disease is a newly defined disease and that it required health care workers to work outside of their fields may have affected their stress levels. In this study, we aimed to determine the relationship among sociodemographic characteristics, the sense of self-efficacy in the diagnosis and treatment of COVID-19, and perceived stress levels of physicians working in a university hospital.
Methods: This was a cross-sectional study. The population included in this study was 327 physicians working in a university hospital at the time of the pandemic. No sampling was performed for this study. This study was completed by a total of 108 physicians (participation level: 33.03%). After being informed about this study, the physicians were asked whether they agreed to participate. Research data were collected with a questionnaire and the Perceived Stress Scale. The questionnaire included questions about physicians' sociodemographic characteristics and feelings of self-efficacy in the diagnosis and treatment of COVID-19.
Results: The total number of skills physicians reported they could perform was higher among specialist physicians and faculty members, those 34 years and older, and those who received training on the diagnosis and treatment of COVID-19 and virus prevention (P=0.04; P=0.01; P<0.001; P<0.001; P<0.001, respectively). In addition, perceived stress levels (PSLs) were found to be lower among those who reported a high total number of skills they could perform, as assessed by the self-efficacy questions (P=0.04).
Conclusion: Although the PSLs of physicians were high, this is expected in a state of emergency such as the pandemic. The sense of self-efficacy regarding COVID-19 improved with training and professional experience. In-service training and shared experiences can both decrease PSLs and improve self-efficacy.

Field experiments were conducted on sandy clay loam soil (Udic Haplustalf) at Central Farm of Agricultural College and Research Institute, Madurai to study the effect of added levels of basic slag with green leaf manure on ADT 36 rice. Addition of graded levels of basic slag viz., 500, 750 and 1000 kg/ha significantly increased the soil available P, Ca, Mg, Fe, Si and the grain and straw yield of rice. Application of 1000 kg of basic slag with 12.50 or 18.75 t/ha of green leaf manure recorded the highest soil available nutrients as well as grain and straw yield of rice over rest of the treatments. The residual crop yield was also significantly increased over NPK treated control by conjunctive use of basic slag with green leaf manure at higher level (1000 kg of basic slag with 18.75 tha of green leaf manure). The superiority of basic slag with green leaf manure in increasing the soil available nutrients was proved only at higher doses.

Field experiments were conducted during rabi 1995-96 and 1996-97 to study the effect of organic and inorganic nitrogen with zinc on growth and yield of rice. The study revealed that application of either green manure (Sesbania aculeata at 6.25 t ha-1 or FYM 12.5 t ha-1 combined with Azospirillum (2 kg ha-1) significantly increased the growth attributes than the combined application of Azolla (I t ha-1). Among the levels of N (112.5, 150 and 187.5 kg ha) with or without 25 kg ZnSO4 ha, combined application of 187.5 kg N ha-1+ 25 kg ZnSO4 ha though recorded significantly the higher growth attributes it was comparable with 150 kg N ha-1+25 kg ZnSO, ha-1. Application of GM with Azospirillum recorded significantly shorter period for 50 per cent flowering, highest number of productive tillers m², filled grains per panicle, panicle length and grain yield (5282 and 5218 kg ha-1) in both the years. Eventhough the highest level of N (187.5 kg har-1) along with Zn application recorded significantly higher yield attributes and yield (5516 and 5376 kg ha-1) it was comparable with 150 kg N ha-1 with Zn.

The floral biology of sesame, despite its autogamous nature, is favourably suited for developing hybrids. To produce hybrid seeds in sesame, different techniques are tried. In the present study, attempt were made to produce large quantities of hybrid seed by hand emasculation and pollination method. It was found that 98.64 per cent of the total cost of hybrid seed production was spent towards emasculation and crossing. On an average, one labour could attend 450 and 275 flower buds respectively for emasculation and pollination in an hour. Only 57 per cent capsule set was recorded and the number of seeds formed in the crossed capsule was also less. The production cost of hybrid seeds was worked out to be Rs. 534.00 per kg.

Successful performance of Surge irrigation system depends chiefly on the design of Surge Cycle Timing parameters and prediction of the net Waterfront Advance times to reach the furrow tailends within the stipulated duration of irrigation. Extensive expermentation with different practical combinations of furrow inflow rates, furrow sizes, length and gradients for selected Surge Cycle Ratios and Numebr of Surges to complete irrigation has resulted in the development of a comprehensive computer model entitled as Surgemode. Validation of the model surgemode has also revealed that the predicted and the observed values of net waterfront advance times to reach furrow tailends lie in an acceptable range of Sto10% deviation while those of the soil moisture distribution efficiency lic in a range of 3108%, making the developed model reliable for design and pre-evaluation of surge irrigation systems to suit the conditions prescribed in the text

Field experiment with rice crop using N fertiliser, FYM, Sesbania aculeata and Azospirillum at Tamil Nadu Agricultural University farm, Coimbatore revealed that there was a depletion of all the major nutrients with the application of fertiliser N alone. Conjoint addition of green manure with fertiliser N improved the status of available N2 organic carbon, NH4-N, Olsen - P and NH4OAc-K. A substantial increase in the fertility status was also observed with the incorporation of FYM with higher doses of N fertilisers. However, there was a drastic reduction of NO3-N in rice soil with all the treatments studied.

A filed experiment was conducted (1995-96) to study the influence of cytozyme growth regulator on Banana cv. Nendran. The experiment consisted of eight treatments (Cytozyme granules alone at 6, 12 and 18 kg levels and in combination with foliar spray of cytozyme Crop at 0.1 per cent) with four replications in Randomized Block design. Results indicated that the application of cytozyme granules @ 18 kg ha-1 along with 0.1 per cent foliar spray increased the availability of 'N' in soil (22.2%) at 30 days after treatment (DAT) (22.2%) and the 'P' was not at all influenced. Available 'K' and exchangeable 'Ca' was increased by cytozyme application towards the maturity stage, while the influence of exchangeable 'Mg' was noticed only on 90 DAT (flowering). The combined effect of soil plus foliar spray also significantly increased the DTPA extractable Zn, Cu and Fe in soil.
