René Girard Among the Theologians
Authors:   Loyola Institute, Trinity College Dublin, Ireland, Kirwan Michael
Published: September 2024

This essay explores the influence of René Girard on the study of religion, and in particular the disciplines of theology. Some commentators have described Girard as a theologian; however, it is more accurate to see his work as “theologically-inflected anthropology.” The implications of this are explained with reference to Girard’s first two books, and a later text, I See Satan Fall Like Lightning. Two factors are important in assessing Girard’s significance for theology: firstly, his conversion, both intellectual and spiritual, at the beginning of his career, and secondly, his collaboration with the Swiss Jesuit theologian, Raymund Schwager. Girard’s contribution becomes evident, as the link between his theological anthropology (or “anthropophany”) and the doctrine of salvation (soteriology) comes into view. The essay concludes with an overview of Girard’s reception by theologians, both sympathetic and critical, and some examples of how mimetic theory is being applied to issues of contemporary Christian living.
Optomechanics and Sensing Phenomena: An Analysis in Classical-quantum Relationship
Authors: Bablu K Ghosh , Swapan K Ghosh
Published: September 2024

As a multi-approach sensing field optomechanics is primarily related to the interaction between optical and mechanical modes interaction. Light-matters dealings in linear to non-linear routes are trails of precision and Quantum Sensing (QS). Light is a wave-matter quantum entity from the classical Electromagnetic (EM) field in which matter is entangled with waves in space-time dimension. The interaction of electromagnetic radiation with the motion of objects and the gravity action is an energy perturbation and complex phenomenon. The energy-mass relation is like wave matter in which a possible link between classical and quantum mechanics is imperative for advanced opto-mechanical sensing. The quantization of mechanical energy and its interaction with light is a process that can be used for diverse sensing purposes. In this study light and gravity-related electromagnetic and mechanical system linkage has been elucidated systematically at macro and micro levels for optomechanical sensing system further development.
Genotyping for specific genomic insertions with Cas12a ssDNA cleavage v1
Authors: Booth David
Published: September 2024

Based on the DETECTR assay, this protocol screens for precise genomic insertions by programming a CRISPR RNA (crRNA) to direct LbCas12a to recognize an amplified genomic locus. This sensitive assay enables the detection of low frequency targets (limit of detection ~0.1-1%) in a plate-based format for high throughput screening. The protocol begins by seeding each well of a 96-well plate with clones or small populations of cells that have been genomically edited. After growing cells to saturation, genomic DNA is rapidly extracted with a buffer that is compatible for direct use in PCR reactions. LbCas12a is directly added to the PCR reaction to detect the presence of specific sequences from the amplified locus. Upon binding to the dsDNA target, LbCas12a can indiscriminately cleave single-stranded DNA (ssDNA). The conjugation of a fluorophore and quencher dye to an ssDNA substrate produces a fluorogenic probe to detect the LbCas12a nuclease activity that depends on dsDNA target recognition. A fluorogenic ssDNA probe is commercially available as a DNase Alert Substrate from Integrated DNA Technologies. This protocol was adapted by David Booth and his Lab at UCSF with special input from Fredrick Leon and Jesus Espinoza-Esparza, building on foundational work from Vicki Deng to optimally extract genomic DNA and to perform plate-based screens.

ANALISIS KEBUTUHAN SISWA SD TERHADAP BAHAN AJAR BAHASA INGGRIS BERBASIS BUDAYA LOKAL SUNDA
Authors: Suharto Pipit Prihartanti
Published: September 2024

Pembelajaran Bahasa Inggris di sekolah dasar sejak enam tahun lalu sudah tidak tercantum lagi dalam kurikulum nasional Indonesia (K-13) yang salah satu alasan penghapusannya adalah bahwa penguatan identitas, budaya, dan bahasa nasional lebih esensial dikembangkan pada jenjang ini. Alasan lain adalah karena kurang tersedianya tenaga pendidik yang kompeten serta buku ajar yang disusun secara terpusat berdasarkan kurikulum nasional yang khusus diperuntukkan bagi sekolah dasar. Namun, kebijakan pemerintah tersebut tidak menghentikan sekolah-sekolah dasar untuk tetap memasukkan Bahasa Inggris ke dalam kurikulum muatan lokalnya. Implikasinya adalah pihak sekolah atau gurulah yang memegang tanggung jawab pengembangan kurikulum Bahasa Inggris untuk pembelajar usia dini.Guna mendukung kebijakan pemerintah namun sekaligus tetap membantu baik pihak sekolah maupun guru dalam melaksanakan pembelajaran Bahasa Inggris pada usia dini, maka salah satu solusinya adalah mengembangkan materi ajar Bahasa Inggris berbasis budaya lokal (local culture-based EFL teaching materials) yang spesifik atau relevan sesuai konteks (context- specific materials) dimana pembelajar usia dini itu belajar. Dengan demikian, pembelajaran Bahasa Inggris bagi usia dini dan penguatan karakter budaya lokal (dan atau nasional) dapat tetap terlaksana. Untuk mencapai tujuan tersebut, sebuah analisis kebutuhan pertama-tama perlu dilakukan di sebuah sekolah dasar yang kemudian diharapkan berkontribusi sebagai basis atau inisiasi pengembangan materi ajar yang mengintegrasikan budaya lokal ke dalamnya. Analisis kebutuhan ini menggunakan kerangka analisis yang diadaptasi dari Mayangsari dkk. (2018). Pengumpulan data akan dilakukan melalui survei terhadap siswa kelas V sekolah dasar, interviu individual dengan guru terkait, interviu grup terfokus dengan siswa, serta dokumentasi. Analisis kebutuhan dalam penelitian ini diharapkan dapat bermanfaat dan berkontribusi terhadap kemajuan pendidikan di tanah air.

Selective protection against single phase earth faults in distribution 6–10 kV cable networks can be performed both with the use of individual (per connection) and centralized devices covering all connections of the protected object. The advantages of centralized devices are reduction of specific (per connection) costs of protection, simplification of its operation and design. Well-known technical solutions in terms of centralized protection devices against this type of damage do not always provide versatility (the possibility to use neutral cables of 6–10 kV in various grounding modes) and high technical perfection (selectivity and stability of operation). Thus, it is relevant to develop a universal centralized protection against single-phase earth faults, ensuring high technical perfection for all types of earth faults in 6–10 kV cable networks with different neutral grounding modes. The authors have used a comprehensive simulation model "cable network – protection device" to study the selectivity and stability of the developed principles of implementation and algorithms for centralized protection against earth faults. The model is designed in SimPowerSystems and Simulink software. The configuration and parameters of the cable network model have been selected considering the key features of 6–10 kV distribution cable networks of industrial and urban power supply systems. A universal centralized protection against all types of earth faults in 6–10 kV cable networks with various neutral grounding modes has been developed. The results of functional tests on the simulation model have confirmed the effectiveness of the developed algorithms of the developed centralized protection for all types of earth faults both in uncompensated and compensated cable networks of 6–10 kV. The proposed technical solution implements a multifunctional multiparametric centralized protection against earth faults. It has such properties as versatility, selectivity, and high stability of operation for all types of earth faults, recognition of types of single-phase earth faults, continuity of action in stable and most dangerous arc intermittent earth faults.

Published: September 2024

Previous studies have investigated brand love in restaurants but have not considered the dynamics of online reviews about restaurant brands. To fill this gap, this study aims to understand how consumers with a high level of love towards restaurant brands defend them in the face of negative reviews on social media. This research, carried out in a Brazilian context, adopts a qualitative approach, analysing 3,979 customer reviews sourced from Instagram through sentiment and categorical content analysis. From the dimensions of brand love, the results showed that customers who love restaurant brands react to negative reviews about them on social media, expressing their positive emotional connection with the companies and acting as their defenders. The study shows that for the restaurant segment, it is relevant to have consumers who love the brand once they help mitigate the effects generated by negative comments online. Furthermore, the research highlights how brand love manifests in restaurant brands' digital context.
Examining the Impact of Gender Differences on Language Expression: A Sociolinguistic Perspective
Authors: Li Ziyi
Published: September 2024

This study explores the impact of gender differences on language expression from a sociolinguistic perspective. Focusing on undergraduate and master’s degree students in China aged between 19 and 25, the research employs a questionnaire and sample analysis methodology to investigate three aspects: frequency of emotional expression, communication style, and topic choice. Results indicate no significant gender differences in frequency and style of verbal expression, with minor differences observed only in topic preferences related to political and economic subjects. These findings suggest that gender does not have a substantial influence on language expression, highlighting a potential cognitive bias in the perception of gender roles in language usage.
Method development and process validation in dermatology: assessing methods of UV exposure for inducing skin tanning and efficacy evaluation of anti-tanning agents

Published: September 2024

Background: Understanding the differential impacts of natural versus artificial UV exposure and validating a method to evaluate tanning prevention products are crucial for advancements in dermatological research and skincare. This study aimed to develop and validate a process for inducing skin tanning using natural sunlight and artificial UV-lamps, determining the optimal UV dosages to induce controlled tanning and erythema.
Methods: Six adults aged 18 to 55 were exposed to natural sunlight and a 365nm UV-lamp, with incremental exposure times and doses. Sunlight exposure was at 7600 μW/cm2 for 20, 35, and 50 minutes, while the UV-lamp provided 78, 97.5, and 117 mJ/cm² doses. Skin tan and erythema were measured using Mexameter® MX-18-probe on days 1, 3, and 7. Test products A and B were applied to evaluate their protective efficacy, with untreated sites as controls. Safety assessments included dermatological evaluations for adverse effects.
Results: Sunlight exposure led to a mean erythema index (EI) increase of 40.22, 42.55-, and 47.12-units post-exposure, and mean melanin index (MI) increase of 37.78, 46.22, and 59.20 units by day 3. UV-lamp exposure resulted in less consistent increases, with maximum EI rise of 12.09 units and MI rise of 7.79 units. Test products significantly prevented tanning and erythema compared to untreated sites, with no adverse effects observed.
Conclusions: Direct sunlight exposure was more effective than artificial UV-light in reliably inducing tanning and erythema, establishing it as a method for such studies. The UV-lamp doses were insufficient for consistent results. The study validated a method for evaluating anti-tanning products, confirming their efficacy and safety. These findings support further research and optimization in UV exposure techniques, standardizing a method to induce tanning using direct sunlight exposure.
Assessing the Distributional Implications of Transition Policies
Authors: Cavallo Eduardo A. , Hoffmann Bridget , Cricci Bruna Dominici
Published: September 2024

Policies to transition to a low-carbon economy in Latin America and the Caribbean will have important distributional impacts. This article aims to assess how these policies affect different economic sectors and socioeconomic groups and to provide policy recommendations for increasing equity and inclusion. Many of the negative impacts that may exacerbate existing inequalities can be reduced or avoided through policies that compensate citizens for higher prices and worse employment opportunities. Furthermore, well-designed transition policies that have inclusiveness as an explicit goal can promote equal access to the benefits of transition policies. Governments can also take this opportunity to broadly strengthen social protection measures to support workers during concurrent labor market disruptions from automation, artificial intelligence, or other sources.
Alternativa geslom – FIDO2 in Passkey
Authors: Hölbl Marko , Kompara Marko
Published: September 2024

Gesla, ki so najpogostejši način overjanje uporabnikov na spletu, imajo številne pomanjkljivosti in jih zato pogosto označujemo kot Ahilova peta varnosti. Zato se venomer pojavljajo težnje k odpravi gesel in eden izmed pomembnih korakov v to smer je overjanje brez gesel (ang. passwordless authentication) s pomočjo tehnologije Passkey, ki je nastala pod okriljem zavezništva FIDO in poveznim standardom FIDO2. Passkey ponuja izpopolnjen in na uporabnika osredotočen pristop k overjanju brez gesel. V bistvu gre za kriptografski par ključev, varno shranjen na uporabnikovi napravi, z možnostjo uporabe na več napravah in operacijskih sistemih ter shranjevanjem v varnih elementih naprav (kot so TPM ali varne enklave). S tem je postopek overjanje poenostavljen, tako da uporabnikom omogoča overjanje s preprostim biometričnim skeniranjem ali overjanje na podlagi naprave, s čimer odpravi potrebo po pomnjenju in upravljanju gesel. Tako Passkey predstavlja naslednji korak v razvoju informacijske varnosti, saj zagotavlja zanesljiv okvir, ki odpravlja pomanjkljivosti tradicionalnih metod overjanja, hkrati pa je usklajen z varnostnimi in uporabnostnimi cilji sodobnih digitalnih komunikacij. V okviru prispevka se bomo osredotočili na predstavitev pojmov, povezanih z overjanjem brez gesel, standardom FIDO2 ter s poudarkom na delovanju tehnologije Passkey. Prav tako bodo predstavljene prednosti in varnostne funkcionalnosti omenjene tehnologije.

Z vse pogostejšo uporabo interneta in migracijo storitev iz fizičnega sveta v digitalni, postajajo vprašanja o varnosti, zasebnosti in digitalnem lastništvu osebnih podatkov vse pogostejša. Ena izmed ključnih tehnologij, ki omogoča razvoj rešitev na tem področju, so ničelno spoznavni dokazi (ang. zero-knowledge proofs, ZKP). ZKP so kriptografski protokoli, pri katerih dokazovalec dokaže pravilnost poljubne trditve preveritelju, ne da bi pri tem razkril dodatne informacije ali svoje podatke. V članku predstavimo ZKP protokole in njihove razlike, s posebnim poudarkom na dveh najpogostejših družinah protokolov: zk-SNARK in zk-STARK. Njihovo uporabno vrednost prikažemo na področju samo-upravljane in decentralizirane identitete ter na področju strojnega učenja. Pri decentralizirani identiteti ZKP omogočajo deljenje podatkov brez razkritja zasebnih informacij, medtem ko pri strojnem učenju omogočajo preverljivost izhodov modelov. To pomeni, da lahko uporabnik preveri, ali je bil za generiranje napovedi dejansko uporabljen pravilno izbran model.

Tekom izvajanja širše raziskave o uporabi strojnega učenja (ang. machine learning - ML) v procesu mikroplaniranja proizvodnje, ki jo štiri leta izvajamo v realnem okolju podjetja Domel, smo odkrili težave z merjenjem točnosti napovedovanja trajanja proizvodnih nalogov (v nadaljevanju PN). Napovedovanje trajanja PN razbremeni planerje in mojstre v proizvodnji ročnega usklajevanja, ko proizvodnja ni sposobna dosegati želenih normativov tehnološkega postopka, ali so prisotne težave z nezanesljivostjo proizvodnega procesa. Ugotovili smo, da v fazi uvajanja novega izdelka v proizvodnjo ML izboljšuje svoje napovedi. Ko smo longitudinalno povečevali število ponovitev PN za enake izdelke, so na meritve začeli vplivati dejavniki nezanesljive proizvodnje in slabšali napovedi trajanja PN. V prispevku prikazujemo uporabljeno metodo za čiščenje podatkov, na podlagi katere smo lahko na izbranem vzorcu izdelkov dokazali, da zaradi nestabilnosti proizvodnega procesa in pomanjkanja zanesljivih podatkov ne moremo trditi, da ML napoveduje trajanje PN bolje od človeka (niti slabše). Predstavljamo izzive pri statističnem dokazovanju te trditve.

Background: Fiber is a distinctive attribute of the alpaca due to its softness qualities; it contains less grease and has a finer cuticle compared to sheep's wool. Therefore, the types of medullation were estimated: non-medullated fibers (NoMed), fragmented medulla (FragMed), discontinuous medulla (DiscMed), continuous medulla (ContMed) and strongly medullated fibers (StrMed), considering the age and sex of Huacaya breed alpacas (Vicugna pacos) under extensive management conditions in high Andean pastures. Methods: Six grams of fiber samples were collected from the mid-side region (located above the third last rib, halfway between the midline of the belly and the midline of the back) of 240 Huacaya alpacas from the district of Macusani, province of Carabaya, Puno, during the year 2022. They were then processed in the Fiber Laboratory of the Faculty of Textile Engineering and Garments at the National University of Juliaca using the FIBER EC V4.0 and FIBER MED V1.0 equipment. Result: The results obtained show that the percentage of non-medullated fibers decreases as the animal’s age increases (1 year= 75.60%, 2 years=69.43%, 3 years=69.05% and greater than 4 years=66.25%) (P≤0.05). The percentage of medullated fibers in animals of 1 year was 24.40%; 2 years, 30.57%; 3 years, 30.95% and greater than 4 years, 33.59% (P≤0.05). The mean fiber diameter in 1-year-old alpacas is 17.32 mm, 2 years=19.49 mm, 3 years = 19.91 mm and 4 years=20.10 mm (P≤0.05). The comfort factor in 1-year-old animals is 99.47%, 2 years with 98.02%, 3-year-olds with 97.01% and those older than 4 years with 96.45% (P≤0.05). Regarding the curvature index, values of 55.86 °/mm were obtained for 1-year-old animals, 53.43 °/mm for 2-year-olds, 53.99 °/mm for 3-year-olds and 52.23°/mm for those older than 4 years (P≤0.05). In conclusion, Huacaya alpacas exhibit low values for the percentage of strongly medullated fibers due to the age and sex of the animal, demonstrating very good fleece uniformity.

Authors: Zulkifli Zulkifli
Published: September 2024

Despite being banned by the government, HTI continues to struggle for Islamic caliphate as a clandestine movement. This study is aimed to explain factors resulting in the relatively successful penetration of caliphate ideology in a changing Malay society, as represented by Bangka Belitung Archipelagic Province. It employed a qualitative approach through the library study of both offline and online data sources in order to gain a holistic comprehension of HTI’s success. The research results elaborate HTI’s mobilization strategies as the internal factor and the context of changing Malay society and the dysfunction of moderate socio-religious organizations as the external factor contribute to HTI’s success in the changing society. Mobilization strategies comprising the intensive implementation of religious learning and preaching, publication, public demonstration, good relation and network with local important figures, and the competent use of communication and information technology become effective in the context of changing Malay society reconstructing identity and seeking solutions to its social and economic problems. In addition, the dysfunction of moderate socio-religious organizations producing a theological vacuum accentuates HTI’s relative victory. Thus, the performance of HTI depends on its internal capabilities and external context and the function of socio-religious organizations in society.

Methodology/Design/Approach – A purposive sampling was drawn to select ten videos uploaded to YouTube during the crisis in Sri Lanka based on keyword searches. A thematic analysis was employed to analyse the verbatim content of the videos using QDA Miner Lite software. Findings – The findings revealed that tourists who share their experiences in YouTube vlogs tend to provide information about the crisis, tourist safety, and their self-reflection as vloggers. They co-create cognitive information and share empathetic content about incidents they have encountered at the destinations. Further, tourists co-create content for different motives: to receive rewards, for entertainment purposes, to help other tourists, and to support affected locals in destinations in crisis areas with their contributions in YouTube travel vlogs. Originality of the research – Vlogging on social media is becoming a popular trend, and tourists’ co-creations on travel vlogs are attracting the attention of many stakeholders in the tourism industry. However, co-creating tourist travel experiences in developing destinations during a crisis through YouTube travel vlogs is still an under-researched area

Published: September 2024

Reticular and cluster materials often feature complex formulas, making a comprehensive overview challenging due to the need to consult various resources. While datasets have been collected for metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and zeolites, among others, there remains a gap in systematically organized information for polyoxometalates. This paper introduces a carefully curated dataset of 1984 polyoxometalate (POM) and related cluster metal oxide formula instances, currently connecting over 2,500 POM material instances. These POM instances incorporate 75 different chemical elements, with compositions ranging from binary to octonary element clusters. This dataset not only enhances accessibility to polyoxometalate data but also aims to facilitate further research and development in the study of these complex inorganic compounds.

This study investigates the comparative performance of autoencoders and traditional machine learning (ML) algorithms in predicting tumor dynamics following Gamma Knife radiosurgery (GKRS) for brain metastases (BMs). The research retrospectively analyzed clinical data from 77 patients (median age: 64 years; 45 males, 32 females) treated at the “Prof. Dr. NicolaeOblu” Emergency Clinic Hospital-Iasi. The dataset comprised 12 variables, including socio-demographic, clinical, treatment, and radiosurgery-related factors. The primary outcome was tumor progression or regression within three months post-GKRS, with 71 cases of regression and 6 cases of progression observed. Traditional ML models—Logistic Regression, Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Extra Trees, Random Forest, and XGBoost—were evaluated, achieving accuracy rates ranging from 0.91 (KNN) to 1.00 (Extra Trees). When incorporating features extracted by autoencoders, the performance of these models generally improved, especially with compression in the bottleneck layer. For instance, Logistic Regression's accuracy increased from 0.91 to 0.94, while SVM's accuracy improved significantly from 0.85 to 0.96. XGBoost consistently performed well across both traditional and hybrid setups, maintaining an accuracy of 0.94 with an AUC of 0.98. The findings suggest that hybrid approaches combining deep learning with traditional ML techniques can significantly enhance predictive accuracy and robustness, particularly in the context of GKRS for BMs. This improved performance has potential implications for more informed clinical decision-making in personalized medicine.

Published: September 2024

Objective Hypertension is one of the most common chronic diseases, affecting more than 20 % of the population. The side effects experienced due to antihypertensive medications such as tired-ness, muscle pain, and insomnia are often a significant predictor of poor adherence to therapy. The goal of the current study is to present the frequency, type, seriousness, and severity of adverse drug reactions reported to the BDA via Individual Case Safety Reports (ICSR) and following differentiation of messages found in more than one patient. Methods We conducted a retrospective analysis of the reported adverse drug reactions (ADR) reported in the Bulgarian Drug Agency database after treatment with antihyperlipidemic medicines, angiotensin-converting enzyme (ACE) - inhibitors, and sartans for the period 2017-2021. Each ICSR form was observed and data for suspected medicine and type of adverse reaction was analyzed. Results The total number of processed notifications for adverse drug reactions (ADR) included in the database is 142. The highest number of ADRs was reported for ARB (58), followed by antihyperlipidemic medicines (55) and ACE inhibitors (29.) Most of the assessed adverse events experienced by more than one patient fall into the probable and related categories based on Global Introspection method classification. Therefore, they have been investigated and are consistent with exposure in the population. Conclusion Cardiovascular medicines from the groups of ACE inhibitors, sartans and statins are with high share of reported ADRs in the BDA system. Some of them are severe and need further investigation.

Published: September 2024

Acid-producing bacteria in pit mud play a crucial role in the fermentation of Chinese liquor, significantly influencing its flavor, taste, and overall quality. This study investigates three strains of anaerobic acid-producing bacteria from pit mud to optimize both single and combined bacterial fermentations for enhanced acid production. Acid production levels were quantitatively measured using gas chromatography-mass spectrometry. The Design Expert software was employed to identify significant nutritional factors affecting the production of hexanoic and butyric acids. These factors were optimized through climbing tests and response surface analysis. The Box-Behnken Design (BBD) experimental design and variance analysis were used to determine the optimal levels of each significant factor. The SJ-1/SJ-3/SJ-8/enriched solution exhibited the highest acid production, with a total acid production of 2216.07±0.10 mg/100 ml. The yields of caproic acid and butyric acid were 801.94±0.11 mg/100 ml and 1167.33±0.14 mg/100 ml, respectively. The optimized fermentation medium for caproic and butyric acid production consisted of 5.1 g/L peptone, 5.04 g/L sodium acetate, and 4.45 g/L sodium butyrate, with a pH of 6.4. Under these conditions, the production of caproic acid and butyric acid reached 1172.73 mg/100 ml and 2382.45 mg/100 ml, respectively. These values represent significant increases (P<0.05) of approximately 46.24% for caproic acid and 104.09% for butyric acid compared to initial levels. The model predicts caproic and butyric acid production to be 1184.21 mg/100 ml and 2387.84 mg/100 ml, respectively, which closely aligns with experimental results. This indicates the model’s effectiveness and provides valuable insights for enhancing acidity in liquor production.

Published: September 2024

Faba bean is grown globally for human consumption and animal feed and is a significant rotation crop in cereal dominant areas in many countries including Australia. It is sensitive to several abiotic stresses, such as drought, frost and high temperatures, especially at the reproductive stage. However, little is known of the upper and lower temperature limits for successful podding. Experiments were conducted over two years at Breeza and Narrabri in north-western New South Wales to assess the impact of temperature on flowering and pod set of three genotypes; Doza, Cairo and IX1148f under field conditions. Flowering nodes were tagged from designated plants in the field and scored for podding, field temperatures were recorded. Optimum maximum temperature for podset ranged from 23.7-26.1 °C and the equivalent minimum temperature was 3.2-3.8 °C. Optimum average daily temperature for podset ranged from 12.7-13.9 °C. The strongest correlations between temperature and podding were observed at minimum temperatures, indicating that low temperatures are more important than high temperatures in determining yield in faba bean.

Published: September 2024

This study presents a reproducible and scalable method for synthesizing silica nanoparticles (SNPs) with controlled sizes below 200 nm, achieved by systematically varying three key reaction parameters: ammonium hydroxide concentration, water concentration, and temperature. SNPs with high monodispersity and controlled dimensions were produced by optimizing these factors. The results indicated a direct correlation between ammonium hydroxide concentration and particle size, while higher temperatures resulted in smaller particles with increased polydispersity. Water concentration also influenced particle size, with a quadratic relationship observed. This method provides a robust approach for tailoring SNP sizes, with significant implications for biomedical applications, particularly in drug delivery and diagnostics. Using eco-friendly solvents such as ethanol further enhances the sustainability and cost-effectiveness of the process.

Published: September 2024

This paper investigates generalized Bayesian (GB) inference in the context of a one-parameter Pareto distribution. The study focuses on the derivation of generalized Bayesian estimators (GBE) and generalized empirical Bayesian estimators (GEBE) for the parameters of the Pareto distribution using type II censored data. In addition, the study investigates a one-sample prediction approach to examine generalized Bayesian prediction (GBP) and generalized empirical Bayesian prediction (GEBP). To evaluate the performance of these estimation and prediction methods, Monte Carlo simulations were performed comparing GBE with GEBE and GBP with GEBP for different parameter values and learning rate parameters (LRP).
