Authors: Sairmorsa Wanti , Tetelepta Edward G. 
Published: February 2025

Indonesia, home to the largest mangrove ecosystem in the world, plays a vital ecological, socio-economic, and socio-cultural role. Mangrove forests, as tropical coastal vegetation communities, grow in tidal areas, providing coastal protection, fish resources, and various ecological benefits. However, mangrove forests are vulnerable to damage from human activities, such as overexploitation and waste disposal. Development demands, particularly the conversion of mangrove forests, lead to ecosystem degradation. Physical, chemical, biological, and socio-economic factors contribute to this damage, with oil pollution and waste disposal posing severe threats. The importance of conservation and sustainable management is emphasized to maintain the sustainability of mangrove ecosystems. This research employs qualitative methods with descriptive and experimental approaches. The descriptive approach is used to understand the research object in its natural conditions, while the experiment is conducted systematically and planned to prove theories. The research approach involves a combination of quantitative methods and qualitative interviews to understand the interaction of research variables deeply. Based on the research findings, factors that need to be considered in mangrove areas include physical, chemical, biological, and social aspects. Physical and chemical parameters, such as temperature, salinity, and water quality, meet the maximum allowable standards. However, there is an increase in heavy metals, mainly dissolved oil, which could threaten the health of the mangrove ecosystem. Changes in mangrove species were also detected, indicating a threat to the sustainability of mangrove plants. Social issues, such as indiscriminate disposal of plastic waste, wood, and glass shards, cause blockages and hinder mangrove growth. Therefore, efforts for protection and sustainable management are necessary to ensure the sustainability of the mangrove ecosystem in the area.

Published: February 2025

Objectives. The work set out to technically and economically analyze servers as computing modules of computing systems of the warehouse scale computer (WSC) class.Methods. The research was carried out using the methods of mathematical analysis and modeling.Results. The article provides a technical and economic analysis of computing modules or servers. Servers are created on the basis of Xeon (Intel) class microprocessors and the like. An overview of the microprocessor subclasses is given along with an indication of server organization options, as well as their main components and primary areas of use. Server reliability is a complex property that may include durability, maintainability and persistence, or certain combinations of these properties depending on the purpose of the object and the conditions of its use. To ensure maximum reliability, backup elements, including arrays of disks and power supplies, as well as backup servers, are used alongside special solutions, including the use of hot swapping and connection, checking and correction of random access memory errors, and temperature control of server compartments.Conclusions. The review of options for organizing servers and their main components allows permits the conclusion that their operation is sufficiently reliable. However, servers integrated into the WSC class have special requirements, namely, continuity of operation in 24/7 mode for long periods of time. This requires the development of methods for assessing the reliability of such highly reliable systems, including backup elements, in relation to hardware and software failures, as well as methods for predicting failures and measures to combat their consequences.

Published: February 2025

Objectives. Multi-position amplitude-phase shift keying (APSK) with a ring-shaped signal constellation is one of the most effective ways for transmitting discrete information in satellite systems. The use of APSK is regulated by several standards. The main are DVB-S2 and VSAT which define both the modulation parameters, and the parameters of the signal constellations. The aim of the paper is to determine the best constellations of 16-APSK and 32-APSK, and provide a minimum BER for cases when the communication channel, along with noise, contains non-fluctuating interference.Methods. Methods of statistical radio engineering, the theory of optimal signal reception, and computer modeling were used.Results. The optimization of ring-shaped constellations of 16-APSK and 32-APSK signals is attained by changing the distribution of points along the radius and phase for a case in which the communication channel, along with noise, contains non-fluctuating interference: frequency-shift keyed, retransmitted, phase-shift keyed, and harmonic ones. The best constellations of 16-APSK and 32-APSK are determined, and a minimum bit error rate is provided.Conclusions. In order to improve the quality of communication in information transmission systems in the presence of non-fluctuating interference, the existing constellations 16-APSK (4, 12) and 32-APSK (4, 12, 16) can be used by changing the ratios between the radii of circles 2.5 for 16-APSK and 2.5/3.9 for 32-APSK. Due to the more efficient use of signal power, the use of constellations with a zero-amplitude point for 16-APSK allows reception noise immunity to be increased. For example, when using constellation (1, 5, 10), the energy gain compared to the standard constellation (4, 12) can reach 1 dB.

Authors: Ortiz Yasmin V. , Pérez-Ramos Daniel W. , Caragata Eric P. , Thongsripong Panpim 
Published: February 2025

This publication provides an overview of dengue fever, focusing on its epidemiological landscape in Florida. Dengue, caused by dengue virus and transmitted through the bites of infected Aedes mosquitoes, is a major global health concern. Florida has experienced local dengue transmissions, and the incidence of dengue is increasing in the state. The biology and ecology of the primary vectors, Aedes aegypti and Aedes albopictus, play important roles in the disease's transmission cycle. No vaccine and no specific antiviral treatments are yet available, and diagnosis is difficult because dengue symptoms overlap with those of other, similar febrile illnesses. Prevention and control strategies, such as mosquito management, are therefore crucial to mitigate disease risks. Alongside urbanization, climate change, and globalization, incidence of dengue is increasing in Florida. Continued vigilance and research will help to combat this public health threat.
Assessment of Cultural Sensitivity in the ChatGPT’s Translation of the Acehnese Chronicle ‘Ali Peureudan’
Authors: Sabrina Sabrina , Takary Ghazali 
Published: February 2025

Cultural sensitivity is an integral aspect in translation to ensure the preservation of context and meanings, allowing the readers to grasp the intended meanings; however, this aspect was often omitted and still highly under-researched. The research aimed to examine cultural sensitivity in the ChatGPT’s English translation of the Acehnese Chronicle of Ali Peureudan originated from Aceh Province, Indonesia. The story contains culturally-specific phrases in Acehnese and Arabic languages. The research was a Comparative Literary Analysis which is descriptive qualitative in nature. The source text (ST) and Target Text (TT) generated by ChatGPT were compared and analyzed carefully using the Translation Quality Assessment developed by Juliane House (2015). There were 26 cultural phrases in total under analysis. The results revealed that 85% of ChatGPT’s renditions of culturally-bound terms were covert, which means that the phrases were adapted to the target language norms (English), such as Allah as ‘God’, Insya Allah as ‘God willing’, and ‘Surat’ as ‘Wish’, causing a loss of cultural nuance, generalization, semantic narrowing, and meaning distortions. Only 15% of the analyzed phrases were translated overly by maintaining their original versions, avoiding diminution of cultural meanings. Of the 15%, only a single word was found to be kept intact in its original version yet accompanied by a meaning description, namely the word Alhamdulillah (Praise be to God). Such strategy protects its originality, avoids erasure of cultural details, as well as provides understanding to the target readers of its intended meaning. This research concludes that ChatGPT still lacks cultural sensitivity in rendering a literary work. This research is expected to be a foundation for those using ChatGPT as a translation tool for such culturally sensitive texts, and provide an input to ChatGPT developers to improve its system for more accurate rendition.

Translanguaging on Social Media by Educated Arabs
Authors: Reima Al-Jarf  
Published: February 2025

Translanguaging is the ability to move smoothly between the languages that a person knows. A sample of Facebook posts written by a sample of educated Arabs was collected. All the participants are native speakers of Arabic and have a good command of English or French as English/French was the medium of instruction in their major area of specialization such as medicine, computer, and engineering. The study aims to find out whether educated Arabs are capable of communicating equally well in both English/French (L2) and Arabic (L1) especially that Arabic is diaglossic having a standard form used in school textbooks, print material and formal situations and a colloquial form used in daily communication with family and friends. Data analysis showed that most educated Arabs are incapable of translanguaging. They communicate better and are more proficient in English/French than Arabic. Their weaknesses are manifested in their use of slang and Colloquial Arabic rather than Standard Arabic. Many completely ignore Standard Arabic spelling and grammar rules. They spell words the way they pronounce them in their local dialect. Many make agreement, definite article attachment, plural formation, and derivation errors. They code mix, i.e., transliterate English/French words and insert them in Arabic posts (cases الكيسز, schemes اسكيمز, share شير). They do not seem to know the Arabic equivalents of simple general and specialized English/French words (center سنتر, neuro نيورو, maps المابس). They even substitute simple Arabic words with English ones (shoes, fans, café, like, comment). It seems that educated Arabs are unable to think in L1 and L2 simultaneously. Their knowledge of English/French surpasses that of Arabic. They transfer the foreign pronunciation and structures to Arabic. Recommendations for reinforcing the native language and enhancing translanguaging skills are given.

Published: February 2025

The charity box is a place to collect alms from the community. Currently, the charity box that we often encounter in the money counting system in the charity box is still required to open the lid of the charity box and count manually. Therefore, a system is needed that can recognize banknote denominations and automatically calculate the nominal amount of banknotes that go into the charity box. The aim of this research is to design and create a system for reading nominal banknotes using a Logitech C3010 webcam and monitoring the number of banknotes using the MIT App Inventor application. In this research, the author uses the template matching method to identify the nominal value of banknotes that go into the charity box. Based on the test results, the template matching method can be implemented to detect nominal banknotes with a threshold value of >0.40 and an effective distance of 20-30 cm so that the nominal money produced is detected very well.

IntroductionAlthough generative artificial intelligence (AI) is ubiquitous, there is little research on how it supports self-efficacy (learners’ belief that they can perform at a particular level on a specific task). The purpose of these studies was to investigate self-efficacy development in a generative AI-based language learning experience.MethodsIn two studies, learners (N = 385) of French/Spanish used AI-based features offering conversation practice and on-demand explanations in a mobile app (Duolingo) for 1 month. Before and after using the features, learners reported their self-efficacy and other perceptions.ResultsIn Study 1, learners who had already used the features felt significantly more prepared to use French/Spanish in real-life situations after 1 month, as did learners in Study 2 who used the features for the first time. Learners in Study 2 also felt significantly more prepared to share their opinions and navigate a city, and reported significantly higher self-efficacy for speaking and understanding grammar and mistakes. Across studies, the majority of learners agreed that the AI-based features effectively supported learning, and reported using their learning outside the app.DiscussionThese results provide the first evidence of enhanced language learning self-efficacy after use of generative AI, building on findings from classroom interventions.

Published: February 2025

BackgroundDue to cosmic radiation bombardment and over 4 billion meteorite and micrometeoroid impacts on the airless Moon, the lunar surface is covered by a layer of fine, reactive dust. Very little is known regarding the toxicity of lunar dust on human physiology. This study assessed airborne lunar dust exposure in rats on localized pulmonary and systemic immune parameters.MethodsRats were exposed to 0 (air only), 20.8 (low), and 60.6 (high) mg/m3 of respirable-size lunar dust for 4 weeks (6 h/day, 5 days/week). Rats were then euthanized either 1 day, 7 days, 4 weeks, or 13 weeks after the last exposure. Peripheral blood and lung lavage fluid samples were collected for analysis. Assays included leukocyte distribution by multicolor flow cytometry and electron/fluorescent microscopy to visualize cell–particulate interactions and lavage/plasma cytokine concentration. Mitogen-stimulated cytokine production profiles, as a measure of cellular function, were performed on whole blood samples only.ResultsUntreated lavage fluid was comprised primarily of pulmonary macrophages. High-dose lunar dust inhalation (60.6 mg/m3) resulted in an influx of both neutrophils and lymphocytes. Although the percentage of lymphocytes increased, the T-cell CD4:CD8 ratio was unchanged. Cytokine analysis of the lavage fluid showed increased levels of IL-1β and TNFα. These alterations generally persisted through the 13-week sampling. Blood analysis showed few systemic immune alterations from the lunar dust inhalation. By week 4, the peripheral granulocyte percentage was elevated in the treated rats. Plasma cytokine levels were unchanged in all treated rats compared to controls; however, altered mitogen-stimulated cytokine production profiles were observed consisting of increased IL-1β and IL-6 and decreased IL-2. There were minimal adverse immune effects, in both lung or peripheral blood, following low-dose exposure to 20.8 mg/m3 lunar dust.ConclusionExposures to high concentrations of lunar dust resulted in persistent lung inflammation and some systemic immune dysregulation that did not subside even 13 weeks after the dust exposure. This information is beneficial in deriving an exposure limit to airborne lunar dust and for spacecraft engineers considering dust mitigation systems in lunar landers or habitats.

Published: February 2025

BackgroundTo date, the non-viral vector Chimeric Antigen Receptor (CAR) T cell preparation platform, exemplified by transposons, has demonstrated significant potential in tumor immunotherapy and yielded positive results in multiple clinical trials. Nonetheless, non-methylated CpG sequences within plasmid DNA can elicit an inflammatory response via Toll-like receptor 9 (TLR9) during CAR-T cell preparation, adversely affecting transgene expression. Additionally, de novo DNA methylation programs promote T cell exhaustion, which poses a significant limitation for CAR-T cell therapy applications.MethodsHigh-throughput liquid protein chip and CBA analyses were utilized to determine the expression levels of inflammatory factors. Flow cytometry and luciferase reporter assays were employed for mutation screening. BALB/c mice and M-NSG mice were used to evaluate the inflammatory response and efficacy of LCG CAR-T in vivo, with TIL grouping detected via immunohistochemistry.ResultsIn this study, we modified the newly discovered Passer (JL) transposon to construct a low-CpG content transposon for CAR-T cell (LCG CAR-T cell) preparation. In vitro experiments demonstrated that LCG CAR-T cells prepared using this new transposon exhibited stronger cytotoxicity. In animal models, LCG CAR-T cells significantly inhibited tumor growth and increased the populations of CD4+CAR-T cells and tumor-infiltrating lymphocytes. Furthermore, LCG CAR-T cells modulated pro-inflammatory cytokine release, thereby reducing in vivo inflammatory responses and surpassing the effects observed with unmodified CAR-T cells.ConclusionsCollectively, our results demonstrate the high safety and efficacy of non-viral, low CpG Passer transposon CAR-T cells, offering new avenues for improving CAR-T cell efficacy while minimizing in vivo inflammation.
