Authors: Weidner Robert , Schmermbeck Katharina , Ott Oliver 
Published: September 2023

Um den Menschen bei vielfältigen Tätigkeiten in verschiedenen Arbeitsumgebungen bestmöglich zu unterstützen, muss das Verhalten von Exoskeletten an die wechselnden Anforderungen anpassbar sein. Zur Realisierung wird die Methode eines übergeordneten Reglers nach dem Prinzip der Zustandsautomaten eingeführt. Aufbauend auf Prozesswissen beschreibt der Zustandsautomat den Arbeitsablauf und erlaubt die Betrachtung sowie die Abstimmung der Unterstützung an die Anforderungen einzelner Tätigkeiten.

To optimally support humans during diverse activities in different work environments, the behaviour of exoskeletons must be adaptable to changing requirements. To enable this adaptation, the method of a superordinate controller based on the principle of state machines is introduced. Building on process knowledge, the state machine describes the workflow and allows the analysis as well as the tuning of the support with respect to the requirements of individual activities.

Authors: Trung Phạm Quang 
Published: September 2023

Chủ nghĩa hậu thuộc địa là một lý thuyết văn hóa - văn học mới ra đời vào thập niên cuối cùng của thế kỷ XX nhưng đã có những ảnh hưởng sâu rộng với tư tưởng của nhân loại, nhất là đối với các nước từng chịu sự thống trị nặng nề về kinh tế, sâu đậm về xã hội của chủ nghĩa thực dân cũ và mới mang tính điển hình như Việt Nam. Đáng tiếc là sự giới thiệu lý thuyết quan trong này ở nước ta hiện nay còn sơ lược, phiến diện, thậm chí lầm lạc, dẫn tới việc vận dụng nó vào thực tế nghiên cứu, sáng tác, phê bình còn nhiều hạn chế. Cùng với việc phân tích, lý giải hiện trạng đó, bài báo đặc biệt tập trung đề xuất một số hướng giải quyết vừa thiết thực trước mắt vừa cơ bản lâu dài, nhằm góp phần đẩy mạnh hoạt động sáng tạo, nghiên cứu văn hóa - văn chương nước nhà lên một trình độ và chất lượng mới, đáp ứng những đòi hỏi ngày một cao của dân tộc và thời đại.

PARALLEL ALGORITHMS OF RANDOM FORESTS FOR CLASSIFYING VERY LARGE DATASETS
Authors: Nghi Do Thanh , Khang Pham Nguyen , Hoa Nguyen Van , Trong Ly Hoang 
Published: September 2023

The random forests algorithm proposed by Breiman is an ensemble-based approach with very high accuracy. The learning and classification tasks of a set of decision trees take a lot of time, make it intractable when dealing with very large datasets. There is a need to scale up the random forests algorithm to handle massive datasets. We propose parallel algorithms of random forests to take into account the benefits of Grids computing. These algorithms improve training and classification time compared with the original ones. The experimental results on large datasets including Forest cover type,KDD Cup 1999, Connect-4 from the UCI data repository showed that the training and classification time of parallel algorithms are significantly reduced.
Response planning during question-answering: does deciding what to say involve deciding how to say it?
Authors: Corps Ruth E. , Pickering Martin J. 
Published: September 2023

AbstractTo answer a question, speakers must determine their response and formulate it in words. But do they decide on a response before formulation, or do they formulate different potential answers before selecting one? We addressed this issue in a verbal question-answering experiment. Participants answered questions more quickly when they had one potential answer (e.g., Which tourist attraction in Paris is very tall?) than when they had multiple potential answers (e.g., What is the name of a Shakespeare play?). Participants also answered more quickly when the set of potential answers were on average short rather than long, regardless of whether there was only one or multiple potential answers. Thus, participants were not affected by the linguistic complexity of unselected but plausible answers. These findings suggest that participants select a single answer before formulation.
MODULAR MOBILE TRAINING AND TESTING COMPLEX
Authors: Haponenko H. , Matvieiev L. , Oliinyk O. 
Published: September 2023

The materials of the article substantiate the need to create a modular mobile training and testing complex for the purpose of training of experimental-combat units (combat units, groups of scientific and technical support, representatives of manufacturing enterprises of robotic complexes (systems) to conduct tests of experimental or serial samples of robotic complexes (systems) in combat conditions.
The experience of creating proving grounds and their further use allowed to shift the emphasis towards their mobility. The main idea that formed the basis of the modular mobile training and testing complex is the ability to perform tasks as assigned in any part of Ukraine in a completely autonomous mode.
The purpose of the main parts of the complex is presented. It is specified which parts the complex consists of. It was found that they can be: mobile (move on their own car chassis); movable (move on platform means of road, air, rail and water transport); combined. It is allowed to add existing stationary structures (buildings) that meet the requirements of state building regulations to the composition of the elements of the complex.
It has been investigated that the elements of the complex must ensure:

official activity of a permanent staff in the number of at least 30 people (military servicemen, employees) and training of an alternating staff in the number of at least 30 people (those who train), in field conditions regardless of the season and time of day;
conducting tests in field (proving ground) conditions;
residence and daily life of personnel;
storage and maintenance of aerial, ground and water based robotic complexes and systems.

It is assumed that the modular mobile training and testing complex will be used in field conditions, at any time of the year and at any time of the day, and as we emphasized earlier, it should ensure autonomous functioning. It is not intended to be used in areas of hostilities.
If necessary, the complex can be supplemented with other elements.
It is proposed to make such a complex from movable modules. Each module can include: a common compartment (at least 90 % of the total internal volume); technical compartment (cabinet); power supply system; life support system. The development and implementation of other necessary components in mobile modules is allowed.
Further scientific research in this field involves the development of a specification for each element, component, module and their agreement with the certification and codification body of the Ministry of Defense of Ukraine.

Published: September 2023

The term “Basic Unmanned Aircraft System” refers to a comprehensive system encompassing both hardware and software components, forming an integral configuration aimed at unmanned aviation operations.
The Unmanned Aircraft System, in its fundamental assembly, comprises an intricate interplay of technological components. These components, ranging from cutting-edge hardware to sophisticated software, collaborate harmoniously to execute tasks that were traditionally accomplished by manned aircraft.
Collaboration between specialized enterprises and research institutions approach holds promise in terms of synergizing the respective expertise of these entities. This symbiotic partnership not only expedites the development process but also introduces the prospect of novel breakthroughs through the fusion of practical experience and theoretical knowledge.
A paramount consideration is the host of advantages that could potentially be reaped from the realization of the Basic System. One such advantage is the projected increase in production volumes. This, in turn, could significantly bolster the capacity to meet defense orders in a shorter timeframe, thereby enhancing national security endeavors.
Furthermore, the article delves into the catalytic effect this innovation could have on scientific research, particularly in prioritized domains. The development of the Basic System could potentially serve as a stimulus for intensified scientific inquiry. The complexity of its design necessitates advances in a multitude of scientific fronts, such as materials science, artificial intelligence, and robotics.
Political and legal aberration: nihilism and weapons
Authors: KORZH I. , KIRIENKO V. 
Published: September 2023

The subject of this study is the current political and legal phenomenon, which is “political and legal aberration”. The study reveals the content of the subject, which is considered, on the one hand, as a manifestation of legal nihilism, which is typical for the actions of public authorities and political structures within the state due to their conscious or unconscious disregard for the norms of international law, carried out in their narrow corporate interests. On the other hand, it is a kind of legal mechanism, a legal weapon, which is used as a result of the subject of international law giving priority to its domestic legislation over international law, carried out with the aim of hybrid aggression, solving its imperial goals of seizing the lands of its neighbors, etc. To this end, and counting on impunity, all sorts of crimes are committed in the occupied and other territories of the victim country. Such a subject of international law, in this case, is the Russian Federation. The article examines the practical manifestations of legal nihilism in various public authorities of Ukraine in modern conditions, analyzes their causes and the onset of negative consequences for the realization of the dream of Ukrainian society - the European integration of Ukraine, joining the family of European, democratic, economically developed countries. Attention is focused on various aspects of the above, including the manifestation of such a negative consequence of legal nihilism as the peculiar desire of public authorities to carry out judicial reform in Ukraine. It is noted that this situation serves as a kind of barrier to the Euro-Atlantic aspirations of the Ukrainian society. It is noted that in modern conditions, when individual subjects of international law use the law itself not as a universal democratic mechanism for regulating social relations, but as a kind of legal weapon against political and legal opponents in order to achieve their own, primarily imperial, mercantile interests, to undermine the existing world law and order, public security systems, etc., thereby destroying the existing systems of international security, the system of established and regulated legal relations, and creating threats to the existence of life itself on the planet. A conclusion is made about the expediency of reformatting the existing international institutions of security and legal relations, or their complete reboot, or even their liquidation and creation of new ones, following the example of the liquidation of the League of Nations and the formation of the current UN.

Published: September 2023

Eye shadow is one of the decorative cosmetic that contains color that is applied to the eyelids. Eye shadows were generally blue, pink, dark red, silver, green, and brown. Natural dyes are derived from plants, animals, and microorganisms. Butterfly pea flower (Clitoria ternatea L.) and secang wood (Caesalpinia sappan L.) are plants that contain natural dyes that can be used as dyes. The two plants were removed by maceration in 70% ethanol. Eye shadow preparation using a combination of extract spissum of butterfly pea flower and secang wood produces eye shadow with a purple color in 3 formulations, namely F3 extract spissum butterfly pea flower and secang wood (3:2), F4 extract spissum butterfly pea flower and secang wood (2:3), F5 extract spissum butterfly pea flower and secang wood (1:4). In the hedonic test, there was no significant difference >0.05% among F3, F4, and F5. Thus, the results of the irritation test showed that the eye shadow cream preparation produced an irritation index of 1.00, namely, mild irritation.
Keywords: Eye shadow, butterfly pea flower, Secang wood.
Reckoning with “Silent Sam”
Authors: Moore Cecelia 
Published: September 2023

The Confederate soldier monument known as "Silent Sam” has occupied a prominent location at the campus entrance since 1913. Students and others have publicly questioned its presence for the last fifty years. In that time, people have gathered there to protest and to rally support for civil rights. From 2015 on, there has been an active student-led movement in favour of its removal, while alumni and heritage groups have resisted. An additional factor is a “monuments law” passed by the state legislature that year which prohibits its removal or alteration. On August 20, 2018, activists pulled down the statue that sits atop of the monument. University leaders are currently engaged in considering its next steps. Most Confederate monuments were erected in courthouse squares and public parks. Silent Sam is one of only two such monuments that stand on public university campuses. This essay considers the debates around Silent Sam, a story that encapsulates every aspect of the national debate over the control of political power, the shaping of public memory, and a long overdue reckoning with American history.
White Memory and White Violence at Elon University
Authors: Irons Charles F. 
Published: September 2023

This essay documents the challenge of addressing incidents of violence with a fragmentary and contradictory historical record, as well as the irony of continuing to center white perspectives by focusing on the perpetrators of anti-Black violence at Elon College. There is unequivocal evidence linking Jacob A. Long, the brother of Elon’s founding President William S. Long, to the 1870 lynching of Reconstruction-Era leader Wyatt Outlaw, but nothing on the President himself. Moreover, the institution’s fourth president, William Harper, published anti-Black screeds and orchestrated a posse to apprehended John Jeffress on suspicion of rape but was conspicuously absent when a second group murdered Jeffress later that same day arrest, but he denied any advanced knowledge of his subsequent abduction and murder. Official statements the University issued about Harper when removing his name from a university building in July 2020 have been plagued by uncertainty surrounding his role in the killing and ultimately obscured as much about his legacy as they have revealed. Perhaps even more problematically, the focus on these sensational acts of white violence has overshadowed the lives and experiences of early Black staff and students at Elon, yet another act of erasure even amid progress towards restorative justice.
The Mass–Metallicity Relation of Dwarf Galaxies at Cosmic Noon from JWST Observations

Published: September 2023

Abstract
We present a study of the mass–metallicity relation (MZR) of 51 dwarf galaxies (M
⋆ ≈ 106.5–109.5
M
⊙) at z = 2–3 from the A2744 and SMACS J0723-3732 galaxy cluster fields. These dwarf galaxies are identified and confirmed by deep JWST/NIRISS imaging and slitless grism spectroscopic observations. By taking advantage of the superior performance of JWST and the gravitational lensing effect, we extend the previous MZR relation at z = 2–3 to a much lower-mass regime down by ≈2.5 orders of magnitude as compared with previous studies. We find that the MZR has a shallower slope at the low-mass end (M
⋆ < 109
M
⊙), with a slope turnover point of ≈109
M
⊙. This implies that the dominating feedback processes in dwarf galaxies may be different from that in massive galaxies. From z = 3, to z = 2, the metallicity of the dwarf galaxies is enhanced by ≈0.09 dex for a given stellar mass, consistent with the mild evolution found in galaxies with higher mass. Furthermore, we confirm the existence of a fundamental metallicity relation (FMR) between the gas-phase metallicity, stellar mass, and star formation rate in dwarf galaxies at z = 2–3. Our derived FMR, which has no significant redshift evolution, can be used as a benchmark to understand the origin of the anticorrelation between the star formation rate and metallicity of dwarf galaxies in the high-z Universe.
Fundamental–Harmonic Pairs of Interplanetary Type III Radio Bursts
Authors: Jebaraj Immanuel Christopher , Krasnoselskikh Vladimir , Pulupa Marc , Magdalenic Jasmina , Bale Stuart D. 
Published: September 2023

Abstract
Type III radio bursts are not only the most intense but also the most frequently observed solar radio bursts. However, a number of their defining features remain poorly understood. Observational limitations, such as a lack of sufficient spectral and temporal resolution, have hindered a full comprehension of the emission process, especially in the hectokilometric wavelengths. Of particular difficulty is the ability to detect the harmonics of type III radio bursts. Here we report the first detailed observations of type III fundamental–harmonic pairs in the hectokilometric wavelengths, observed by the Parker Solar Probe. We present a statistical analysis of the spectral characteristics and polarization measurements of the fundamental–harmonic pairs. Additionally, we quantify various characteristics of the fundamental–harmonic pairs, such as the time delay and time profile asymmetry. Our report concludes that fundamental–harmonic pairs constitute a majority of all type III radio bursts observed during close encounters when the probe is in close proximity to the source region and propagation effects are less pronounced.
Enhanced Classroom Engagement: Implementation of an Inclusive Teaching Strategy
Authors: Charania Nadia Ali Muhammad Ali 
Published: September 2023

Background:
The coronavirus disease 2019 (COVID-19) pandemic posed challenges to nursing faculties, including transitioning to a virtual teaching platform and ensuring inclusivity, active engagement, and social justice, which are the hallmarks of excellence in nursing education. A three-step teaching strategy called enhanced classroom engagement (ECE-TS) was created.

Method:
The first step in ECE-TS required groups of students to read the assigned article and share five takeaways before class. The second step required each group to discuss and prepare a presentation using a rubric. The final step required each group to give a presentation to the class.

Results:
Students noted ECE-TS promoted (a) individual learning; (b) collective learning; (c) inclusivity; (d) connection among students; (e) change in the classroom environment; and (f) generated proposals for future directions related to ECE-TS.

Conclusion:

ECE-TS, which is a promising strategy that promotes social justice, must be tested across teaching formats and programs.
