Authors: Ward Laura , Subburaj Anitha , Demir Ayda , Chamana Manohar , Bayne Stephen B.
Published: March 2024

Autonomous grid-forming (GFM) inverter testbeds with scalable platforms have attracted interest recently. In this study, a self-synchronized universal droop controller (SUDC) was adopted, tested, and scaled in a small network and a test feeder using a real-time simulation tool to operate microgrids without synchronous generators. We presented a novel GFM inverter control adoption to better understand the dynamic behavior of the inverters and their scalability, which can impact the distribution system (DS). This paper provides a steady-state and transient analysis of the GFM power inverter controller via simulation to better understand voltage and frequency stabilization and ensure that the critical electric loads are not affected during a prolonged power outage. The controllers of the GFM inverter are simulated in HYPERSIM to examine voltage and frequency fluctuations. This analysis includes assessing the black start capability for photovoltaic microgrids, both grid-connected and islanded, during transient fault conditions. The high photovoltaic PV penetration levels open exciting opportunities and challenges for the DS. The GFM inverter control demonstrated appropriate response times for synchronization, connection, and disconnection to the grid. The DS has become more resilient and independent of fossil fuels by increasing the penetration of inverter-based distributed energy resources (DERs).
Place-Based Adaptation through Network Governance

Published: March 2024

Following the inception of Climate Change Adaptation (CCA) within the UNFCCC in 1992, national CCA plans began to emerge around 2008. However, identifying successful cases of adaptation remains challenging. This is because CCA policies often stop at planning, with selective reporting of relevant projects. Recognizing that planning is not the same as actual delivery, substantial gaps persist in connecting these plans to concrete actions, hindering successful adaptation. This paper explores this implementation deficit through the examination of three different governance modes (hierarchies, markets, and networks). Drawing on a policy review (desk study), a qualitative online survey, and semi-structured interviews with professionals engaged in local CCA policies, we identified enablers of effective adaptation policy progress by comparing the Edinburgh and Glasgow city regions. Despite their close spatial and relational proximity, these two city regions have distinct administrative geographies, political leadership, and adaptation-related networks, which identify unique local contexts sufficient to drive different CCA progress. We noted more CCA progress when specific resources included coordinators (dedicated staff) and fiscal supplements, along with regional networks connecting local communities and strengthening partnerships while sharing common values such as reputational opportunities in the Glasgow city region. These findings shed light on effective adaptation governance modes that require not only a deep understanding of place-based contexts but also the presence or nurturing of broader and reinforced networks.
The Industrial Application of Artificial Intelligence-Based Optical Character Recognition in Modern Manufacturing Innovations
Authors: Tang Qing , Lee YoungSeok , Jung Hail
Published: March 2024

This paper presents the development of a comprehensive, on-site industrial Optical Character Recognition (OCR) system tailored for reading text on iron plates. Initially, the system utilizes a text region detection network to identify the text area, enabling camera adjustments along the x and y axes and zoom enhancements for clearer text imagery. Subsequently, the detected text region undergoes line-by-line division through a text segmentation network. Each line is then transformed into rectangular patches for character recognition by the text recognition network, comprising a vision-based text recognition model and a language network. The vision network performs preliminary recognition, followed by refinement through the language model. The OCR results are then converted into digital characters and recorded in the iron plate registration system. This paper’s contributions are threefold: (1) the design of a comprehensive, on-site industrial OCR system for autonomous registration of iron plates; (2) the development of a realistic synthetic image generation strategy and a robust data augmentation strategy to address data scarcity; and (3) demonstrated impressive experimental results, indicating potential for on-site industrial applications. The designed autonomous system enhances iron plate registration efficiency and significantly reduces factory time and labor costs.
Enzyme-Assisted Circular Additive Manufacturing as an Enabling Technology for a Circular Bioeconomy—A Conceptual Review
Authors: Protte-Freitag Kristin , Gotzig Sophia , Rothe Hannah , Schwarz Oliver , Silber Nadine , Miehe Robert
Published: March 2024

Additive manufacturing (AM) is a decisive element in the sustainable transformation of technologies. And yet its inherent potential has not been fully utilized. In particular, the use of biological materials represents a comparatively new dimension that is still in the early stages of deployment. In order to be considered sustainable and contribute to the circular economy, various challenges need to be overcome. Here, the literature focusing on sustainable, circular approaches is reviewed. It appears that existing processes are not yet capable of being used as circular economy technologies as they are neither able to process residual and waste materials, nor are the produced products easily biodegradable. Enzymatic approaches, however, appear promising. Based on this, a novel concept called enzyme-assisted circular additive manufacturing was developed. Various process combinations using enzymes along the process chain, starting with the preparation of side streams, through the functionalization of biopolymers to the actual printing process and post-processing, are outlined. Future aspects are discussed, stressing the necessity for AM processes to minimize or avoid the use of chemicals such as solvents or binding agents, the need to save energy through lower process temperatures and thereby reduce CO2 consumption, and the necessity for complete biodegradability of the materials used.

Published: March 2024

The efficacy of adeno-associated virus (AAV)-based gene therapy is dependent on effective viral transduction, which might be inhibited by preexisting immunity to AAV acquired from infection or maternal delivery. Anti-AAV neutralizing Abs (NAbs) titer is usually measured by in vitro assay and used for patient enroll; however, this assay could not evaluate NAbs’ impacts on AAV pharmacology and potential harm in vivo. Here, we infused a mouse anti-AAV9 monoclonal antibody into Balb/C mice 2 h before receiving 1.2 × 1014 or 3 × 1013 vg/kg of rAAV9-coGAA by tail vein, a drug for our ongoing clinical trials for Pompe disease. The pharmacokinetics, pharmacodynamics, and cellular responses combined with in vitro NAb assay validated the different impacts of preexisting NAbs at different levels in vivo. Sustained GAA expression in the heart, liver, diaphragm, and quadriceps were observed. The presence of high-level NAb, a titer about 1:1000, accelerated vector clearance in blood and completely blocked transduction. The AAV-specific T cell responses tended to increase when the titer of NAb exceeded 1:200. A low-level NAbs, near 1:100, had no effect on transduction in the heart and liver as well as cellular responses, but decreased transduction in muscles slightly. Therefore, we propose to preclude patients with NAb titers > 1:100 from rAAV9-coGAA clinical trials.

The development of prophylactic vaccines is important in preventing and controlling diseases such as visceral leishmaniasis (VL), in addition to being an economic measure for public health. Despite the efforts to develop a vaccine against human VL caused by Leishmania infantum, none is available, and the focus has shifted to developing vaccines against canine visceral leishmaniasis (CVL). Currently, commercially available vaccines are targeted at CVL but are not effective. Different strategies have been applied in developing and improving vaccines, such as using chimeric proteins to expand vaccine coverage. The search for patents can be a way of tracking vaccines that have the potential to be marketed. In this context, the present work presents a summary of immunological aspects relevant to VL vaccine development with a focus on the composition of chimeric protein vaccines for CVL deposited in patent banks as an important approach for biotechnological development. The resulting data could facilitate the screening and selection of antigens to compose vaccine candidates with high performance against VL.
Water Quality of Roof-Harvested Drinking Water Tanks in a Rural Area near a Gold and Copper Mine: Potential Health Risk from a Layer of Metal-Enriched Water and Sediment
Authors: Wright Ian A. , Christie Anna , Gilpin Amy-Marie
Published: March 2024

This study investigated the drinking water quality of house water tanks that harvested roof runoff in a rural area surrounding a large copper and gold mine in Central Western New South Wales (NSW). Water was sampled from (1) the tops of water tanks, (2) the bottoms of water tanks, and (3) kitchen taps. Water samples collected from the bottoms of tanks were turbid with suspended sediment. Concentrations of metals (lead, nickel, arsenic and manganese) from bottom-of-tank water samples often exceeded Australian drinking water guidelines. Overall, 37.2% of samples from bottoms of tanks exceeded arsenic guidelines (<10 µg L−1). The mean concentration of lead in water from bottoms of tanks was 695 µg L−1, with 18.6% of these samples exceeding lead guidelines (<10 µg L−1) by >100 times. Our results highlight the risk of contaminated water and sediment at the bottoms of tanks. Further investigation of private household drinking water tanks is recommended for properties in other rural areas, including areas with and without nearby mining activity. We describe a layer of contaminated water and sediment at the bottoms of water tanks, near the water outlet, which is a potential contamination pathway and substantial health risk for house water supplies.

Published: March 2024

Fish protection is a priority in regions with ongoing and planned development of hydropower production, like the Mekong River system. The evaluation of the effects of turbine passage on the survival of migratory fish is a primary task for informing hydropower plant operators and authorities about the environmental performance of plant operations. The present work characterizes low pressures and collision rates through the Kaplan-type runners of the Xayaburi hydropower station. Both an experimental method based on the deployment of Sensor Fish and a numerical strategy based on flow and passage simulations were implemented on the analysis of two release elevations at one operating point. Nadir pressures and pressure drops through the runner were very sensitive to release elevation, but collision rates on the runner were not. The latter showed a frequency of occurrence of 8.2–9.3%. Measured magnitudes validated the corresponding simulation outcomes in regard to the averaged magnitudes as well as to the variability. Central to this study is that simulations were conducted based on current industry practices for designing turbines. Therefore, the reported agreement helps turbine engineers gain certainty about the prediction power of flow and trajectory simulations for fish passage assessments. This can accelerate the development of environmentally enhanced technology with minimum impact on natural resources.

Published: March 2024

El objetivo de este artículo consiste en abordar algunos argumentos de la filosofía de J. Rancière relacionados con la necesidad de repensar el comunismo. La hipótesis de trabajo insiste en señalar que Rancière no defiende ningún proyecto comunista. Esto al menos por tres razones: no hay igualdad de las inteligencias, el comunista funge como profesor explicador en aras de concientizar a los embrutecidos, el comunismo pertenece a una temporalidad histórica teleológica, lo que a su vez supone un aplazamiento de la emancipación. Finalmente, cerramos este diálogo con las posibilidades presentes de esta otra forma de concebir la igualdad y la emancipación.

Published: March 2024

The use of the metaverse in education has gained increasing attention as a potential supplement to traditional teaching methods. This study aimed to investigate the impact of experiential learning on students' intent to use metaverse learning platforms and to explore how the metaverse can support these approaches. The study included participants from three countries and used metaverse scenes, such as a restaurant or Hong Kong scene, to complete learning tasks and interact with Non-Player Characters (NPCs) to complete assessments over a semester. The results of a correlational analysis showed that pedagogical factors had a greater impact on students' intent to use the metaverse for educational purposes than technical factors, which was unexpected. However, the study also identified challenges in adapting content to match the needs and skills of students who may not be familiar with games, as well as using the metaverse for more advanced pedagogical approaches, due to limitations in integrating content. Based on the findings, recommendations for educators, designers, and researchers are provided to enhance the effectiveness of metaverse-based education. Overall, the results of this study suggest that the metaverse can be a valuable addition to traditional teaching methods.

CHANGES IN TELOMERE LENGTH IN LEUKOCYTES OF MALE RHESUS MACAQUES OF DIFFERENT AGES
Authors: Тимина М.Ф. , Павлова Л.Е. , Киргинцев Р.М. , Агумава А.А.
Published: March 2024

Теломеры представляют собой специализированные концевые участки хромосом, обеспечивающие стабильность последних. Удвоение ДНК при делении клетки связано с укорочением теломер вследствие феномена концевой недорепликации. По мере деления клеток укорочение длины теломер считается одной из важнейших причин старения клетки. Оценка длины теломер до настоящего времени остается предметом научных исследований в области геронтологии и не применяется в клинической практике. Чаще всего в качестве модельного объекта изучения процессов старения используют грызунов, однако нейроэндокринные механизмы, влияющие в том числе на регуляцию процесса старения, отличаются у грызунов и человека. Наиболее близким в филогенетическом отношении к человеку модельным объектом являются обезьяны, в частности макаки резусы — один из чаще всего используемых в биомедицинских исследованиях представителей Старого Света. Однако данные об изменении длины теломер у низших обезьян с возрастом крайне немногочисленны. Мы изучили абсолютную среднюю длину теломер ДНК лейкоцитов крови у 29 клинически здоровых самцов макак резусов 4–24 лет методом количественной ПЦР. Полученные данные не соответствовали нормальному характеру распределения, а корреляционный анализ показал отсутствие значимой зависимости длины теломер от возраста животных (rs=0,27, p>0,05). Таким образом, наше исследование не подтверждает зависимость изменения средней длины теломер лейкоцитов крови с возрастом.

Telomeres are specialized terminal sections of chromosomes that ensure the stability of the latter. DNA duplication during cell division is associated with telomere shortening due to the phenomenon of terminal underreplication. As cells divide, shortening of telomere length is considered to be one of the most important causes of cell aging. Estimation of telomere length still remains the subject of scientific research in gerontology and it is not used in clinical practice. Most often, rodents are used as a model object for studying the aging process, but the neuroendocrine mechanisms that influence, among other things, the regulation of the aging process differ in rodents and humans. The model objects closest in phylogenetic relation to humans are monkeys. In particular, Rhesus macaques is one of the representatives of the Old World most often used in biomedical research. However, data on age-related changes in telomere length in monkeys are extremely scarce. We studied the absolute average length of telomeres in DNA from blood leukocytes of 29 clinically healthy male rhesus monkeys aged from 4 to 24 years using quantitative PCR-method. The data obtained did not correspond to the normal distribution and the correlation analysis showed the absence of a significant dependence of telomere length on the age of the animals (rs=0,27; p>0,05). Thus, our study does not confirm the dependence of changes in the average length of telomeres of blood leukocytes with age.
The Landing and Liberation: A Historiography of the Korean War's Operation Chromite, September 1950
Authors: Matusheski Zachary M.
Published: March 2024

A review of Operation Chromite’s basic history is necessary to fully understand the historiographical trends and available archival resources. To adequately capture the campaign’s origins, historical analysis must begin not in September 1950 but with U.S. leaders’ contradictory approach to security after World War II. On the one hand, the United States took a leading role in world security, forming numerous alliances and international institutions in the context of emerging Cold War rivalry. On the other hand, U.S. military forces atrophied after 1945. Imposition of defense budget ceilings and other efforts by the Harry S. Truman administration, abetted by a thrifty Congress, left a shell of a force in place. Postwar cuts left units undermanned and at low levels of readiness. The Marine Corps fought an especially difficult political battle to prove the value of Marine air support and a Marine expeditionary capability.

STRUCTURE AND MEASUREMENT OF UNIVERSITY FINANCIAL RISK
Authors: Dong Weihua , Cai Yonghong
Published: March 2024

Since the 1990s, higher education in China has expanded significantly. In 2020, the gross enrollment rate will reach 54.4%, and the total number of students in higher education accounts for one-fifth of the total scale of higher education in the world, ranking first in the world in terms of scale. The scale of higher education in China has grown, and the continuous increase in investment in higher education funds has increased the difficulty of controlling financial risks. Strengthening the prevention and control of financial risks in colleges and universities and strengthening the construction of internal control will be of great significance to the healthy development of universities. To understand the sources and causes of financial risks in universities, this study interviews the financial staff of S University and constructed a structural map of financial risks in universities using the grounded theory method to obtain data. The researchers compiled a questionnaire to study the financial risk of universities, distributed and received back 308 questionnaires at S University. By analyzing the survey data, the constructed structure of the financial risks of the university was verified.
RESEARCH ON EMPIRICAL DISTRIBUTIONS OF INDEX RETURNS: EVIDENCE FROM INTERNATIONAL MARKETS
Authors: Maga Anastasia , Dryver Arthur
Published: March 2024

The paper reviews the currently held and quite persistent assumptions about the statistical distributions behind financial market returns used to make inferences for the purposes of risk management. We use data from 30 years of daily observations from the 15 largest and oldest stock price indices around the world and test the return data against the most popularly assumed distributions, breaking the data arrays into 100, 250, 750, and 250-day estimation windows at 0.95 and 0.99 confidence levels. We find returns in different estimation windows to be inconsistent with single distributions. When returns in short windows fit Gaussian distributions better, returns in longer estimation windows do not fit any suggested distributions at all. The normal distribution seems to be a better choice for 100-day windows, with longer window rejection rates for all suggested distributions being too high for reliable inference.

Authors: Ren Chengzhi , Shang Hongyan , Cheng Yanhong
Published: March 2024

The principal responsibility system under the leadership of the party organization is a leadership and management system that emerged during China's education reform. After many changes and developments, it has now been widely used in primary and secondary schools in China. The establishment and implementation of this system enabled China's education to develop rapidly. However, with the development of the times and the progress of society, this system must also keep pace with the times to adapt. A conceptual model is built based on the relationship between the school's organizational structure, organizational decision-making, organizational justice, and organizational performance. Taking Baise City No. 5 Middle School as an example, it takes the four relationships between the "school management model, school decision-making, management justice, and management effectiveness." "Interrelationship" as the core topic, a scientific and reasonable questionnaire was set up, 163 school teachers were measured, and then statistical methods were used to analyze and verify the hypotheses proposed in this article. Finally, based on the empirical conclusions, this article provides suggestions and references for schools to implement the principal responsibility system under the leadership of the party organization to improve the system and ensure the healthy operation of this system.
