An Ensemble Random Forest Model for Seismic Energy Forecast
Authors: Shukla Sukh Sagar , Dhanya Jaya , Kumar Praveen ,   Priyanka, Dutt Varun
Published: October 2024

Abstract. Seismic energy forecasting is critical for hazard preparedness, but current models have limits in accurately predicting seismic energy changes. This paper fills that gap by introducing a new ensemble random forest model designed specifically for seismic energy forecasting. Building on an existing paradigm, provided by Raghukanth et al. (2017), the global energy time series is decomposed into intrinsic mode functions (IMFs) using ensemble empirical mode decomposition for better representation. Following this approach, we split the data into stationary (IMF1) and non-stationary (sum of IMF2-IMF6) components for modeling. We acknowledge the inadequacy of intrinsic mode functions (IMFs) in capturing seismic energy dynamics, notably in anticipating the final values of the time series. To address this restriction, the yearly seismic energy time series is also fed along with the stationary and non-stationary parts as inputs to the developed models. Here, we employed Support Vector Machine (SVM), Random Forest (RF), Instance-Bases learning (IBk), Linear Regression (LR), and MultiLayer Perceptron (MLP) algorithms for the modelling. Furthermore, the five models discussed above were suitably employed in a novel regression-based ensemble random forest algorithm to arrive at the final predictions. The root mean square error (RMSE) obtained in the training and testing phases of the final model were 0.127 and 0.134, respectively. It was observed that the performance of the developed ensemble model was superior to those existing in literature (Raghukanth et al., 2017). Further, the developed algorithm was employed for the seismic energy prediction in the active Western Himalayan region for a comprehensively compiled catalogue and the mean forecasted seismic energy for year 2024 is 7.21 × 1014 J. This work is a pilot project that aims to create a forecast model for the release of seismic energy globally and further application at a regional level. The findings of our investigation demonstrate the possibility of the established method in the accurate seismological energy forecast, which can help with appropriate hazard preparedness.

Published: October 2024

Abstract. Biological soil crusts (biocrusts hereafter) cover a substantial proportion of the dryland ecosystem and play crucial roles in ecological processes such as biogeochemical cycles, water distribution, and soil erosion. Consequently, studying the spatial distribution of biocrusts holds great significance for drylands, especially on a global scale, but it remains limited. This study aimed to simulate global-scale investigations of biocrust distribution by introducing three major approaches, namely spectral characterization indices, dynamic vegetation models, and geospatial models, while discussing their applicability. We then summarized the present understanding of the factors influencing biocrust distribution. Finally, to further advance this field, we proposed several potential research topics and directions, including the development of a standardized biocrust database, enhancement of non-vascular vegetation dynamic models, integration of multi-sensor monitoring, extensive use of machine learning, and a focus on regional research co-development. This work will significantly contribute to mapping the biocrust distribution and thereby advance our understanding of dryland ecosystem management and restoration.
The merged methods and the dialogic research approach
Authors: Gradovski Mikhail
Published: October 2024

The history of the merged methods started in 1949, more than seventy years ago (Gobo, Fielding, La Rocca, & van der Vaart, 2022). The introduction of the merged methods as the new group of methods in Social Science heralded a new era of research more than ten years ago. It is timely to ask why these methods should be of interest to the partisans of the dialogic approach and how the merged methods can be strengthened and developed by the existing tools from the arsenal of the dialogic approach.

Elliptic bootstrapping and the nonlinear Cauchy–Riemann equation
Authors: Zhang Jessica
Published: October 2024

The goal of this paper is to deduce a nonlinear elliptic regularity result from a linear one. In particular, elliptic bootstrapping is a powerful method to determine the regularity of a solution to a partial differential equation. We apply elliptic bootstrapping and linear elliptic regularity to the nonlinear Cauchy–Riemann equation. In doing so, we generalize the fundamental analytic result that holomorphic functions are automatically smooth. In particular, we show that, under certain conditions, the same is true for so-called J-holomorphic functions. We conclude by discussing how this nonlinear regularity result relates to ideas in symplectic geometry.

Developing economies across the world face high public corruption and weak financial management, and the role of sound audit practices in shaping the narratives is still at the exploring stage in most countries in sub-Saharan Africa. This research explores the nexus between public audit reforms and public sector financial management using survey research design and Nigeria as a case study. Participants in the study were drawn from The Office of the Auditor General of the Federation (OAuGF) Headquarter in Abuja. Agency theory anchored this study and simple descriptive analytics was used in testing the seven hypotheses. The research established that: the recent audit reforms carried out in Nigeria are considered necessary for better public sector financial management; Nigeria’s audit system has a strong connection with public sector financial management; there is a need for the establishment of Federal Audit Service Commission (FASC) in Nigeria; the recent audit reforms will block treasury loot and leakages in Nigerian public funds management; Nigeria needs effective audit laws to wholesomely fight corruption through recent audit reforms; and the recent Nigerian audit reforms embrace integrity, transparency and accountability in the management of public funds. The study makes the following recommendations: there is a need for audit staff orientation and professional development in order to promote their overall productivity and efficiency; there is a need for the establishment of Federal Audit Service Commission (FASC) in order to promote the independence of Nigerian Audit system from executive interferences; Nigeria audit laws should be strengthened to curtail fund leakages, wastages of public property, and promotion of value-for-money expenditures; and the recent audit reforms carried out by the government of Nigeria should be sustained and given all necessary supports in order to achieve the desired results.

An Automatic Plants Leaf Disease Identification Method Based on A New Proposed Optimized Convolutional Neural Networks Using Symbiotic Organism Search Algorithm
Authors: Zahra Akeshteh
Published: October 2024

This study presents a novel method for accurately and efficiently classifying plant leaves based on different diseases and health conditions. The approach combines deep learning (DL) and optimization techniques. The model's hyperparameters are optimized using the Symbiotic Organism Search (SOS) algorithm, while a convolutional neural network (CNN) is employed for disease classification. CNNs are effective in identifying distinctive features that aid in distinguishing various classes. The Plant Village dataset is utilized, and data augmentation is performed to enhance the model's performance. The optimized CNN, which does not require segmentation, achieves a classification accuracy of 97.29% for the test set (8,777 images) and 99.89% for the training set (70,295 images). Precision and recall values of 97.33% and 97.32% are attained, respectively. The proposed method is compared to primary CNN models on the Leaf disease database, as well as two well-known pre-trained networks (VGG-16 and VGG-19), using five performance measures. The results demonstrate the superior performance and effectiveness of the developed method. This research contributes to a fast and accurate approach for leaf disease classification, with potential applications in other image classification tasks and benefits for agriculture, orchards, and plant disease identification. Furthermore, a comparison with three similar studies reveals that the proposed network achieves higher accuracy with fewer trainable parameters and computational requirements.
Performance Analysis of Reits and Invits in India: A Comparative Study with the Nifty 50
Authors: Amit Bathia
Published: October 2024

This paper investigates the performance of Real Estate Investment Trusts (REITs) and Infrastructure Investment Trusts (InVITs) in India compared to the Nifty 50 index, using a series of financial models including the Sharpe Ratio, Mann-Whitney U test, Chi-square proportion test and Pearson’s Correlation. The study focuses on whether REITs and InVITs consistently outperform traditional investments like the Nifty 50 in terms of returns and risk-adjusted returns. Despite the significant capital inflow and growing interest in alternative investments, there is limited research focused on the Indian market, where macroeconomic conditions, regulatory changes, and investor sentiment play a crucial role. This paper fills that gap by exploring the risk-return profiles, performance during periods of market volatility, and potential for portfolio diversification provided by these instruments.

Dual labor markets and the equilibrium distribution of firms
Authors: Pijoan-Mas Josep , Roldan-Blanco Pau
Published: October 2024

We study the effects of dual labor markets (i.e. the co-existence of fixed-term and open-ended contracts) on the allocation of workers within and across firms, the equilibrium distribution of firms, aggregate productivity, and welfare. Using rich Spanish administrative data, we document that the use of fixed-term contracts is very heterogeneous across firms within narrowly defined sectors. In particular, there is a strong relationship between the share of temporary workers and firm size, which is positive when looking at within-firm variation but negative when looking at the variation between firms. To explain these facts, we use a directed search model of multi-worker firms, with ex-ante firm heterogeneity in technology types, and ex-post firm heterogeneity in transitory productivity, the composition of employment by contract type (fixed-term or open-ended) and human capital accumulated on the job. In counterfactual exercises, we find that limiting the use of fixed-term contracts decreases the share of temporary employment and increases aggregate productivity, but it also reduces total employment and leads to an overall decline in total output and welfare. The increase in productivity comes from an improved selection of firms, which more than offsets an increased misallocation of workers across firms.
A macroeconomic model of banks’ systemic risk taking
Authors: Abad Jorge , Martínez-Miera David , Suárez Javier
Published: October 2024

We study banks’ systemic risk-taking decisions in a dynamic general equilibrium model, highlighting the macroprudential role of bank capital requirements. Banks decide on their unobservable exposure to systemic shocks by balancing risk-shifting gains against the value of preserving their capital after such shocks. Capital requirements reduce systemic risk taking, but at the cost of reducing credit and output in calm times, generating welfare trade-offs. We find that systemic risk taking is maximal after long periods of calm and may worsen if capital requirements are countercyclically adjusted. Removing deposit insurance introduces market discipline but increases the bank capital necessary to support credit, implies lower (though far from zero) optimal capital requirements and has nuanced social welfare effects.

Introduction: The lentiform fork sign is a unique magnetic resonance imaging (MRI) appearance of the basal ganglia believed to be due to acute metabolic acidosis and seen in several conditions that result in metabolic acidosis such as uremic encephalopathy.

Case Report: We present the case of a 76-year-old hypertensive and diabetic male patient with end-stage renal failure on dialysis, whose brain MRI revealed bilateral symmetrical T2W and fluid-attenuated inversion recovery hyperintensities in the basal ganglia, surrounded by a hyperintense rim delineating the lentiform nuclei, giving rise to the lentiform fork sign.

Conclusion: We describe this under-reported unique sign, the lentiform fork sign, in an end-stage renal disease patient, whose brain MRI revealed this sign to highlight the significance of this sign, which has been widely reported to be associated with uremic encephalopathy.
Social Context Of Bengali Proverbs: A Selective Study
Authors: Haque Md. Imdadul
Published: October 2024

Humans are inherently social creatures, and as such, they naturally gravitate towards forming societies. Living within these societies fosters a complex web of human relationships, which inevitably leads to relationship dynamics and tensions. These interactions often reflect the broader societal context, making society and its culture deeply interconnected with the proverbs and wisdom passed down through generations. Sociologists, in particular, recognize the significance of proverbs as the voice of society. They interpret these proverbs to uncover various societal patterns, including inconsistencies, injustices, and forms of oppression. In Assam, Bengali proverbs serve as a cultural lens through which the interrelationship between society and individuals is observed and understood. These proverbs act as reminders of how society influences personal experiences, beliefs, and values. By examining such sayings, it is possible to reveal the profound connection between social norms and individual behavior. This discussion report aims to further explore this concept, using relevant proverbs to illustrate the ways in which they reflect societal dynamics. Through this effort, the report seeks to expand the understanding of the relationship between society and its members, shedding light on the cultural significance embedded in everyday expressions.

Waste tires recycling and upcycling technologies are crucial for further realization of circular economy strategies. Therefore, improvement of already existed and searching for new methods of waste tires in sustainable concrete applications are fully justified. This research is focused on improving the mechanical response of rubberized self-compacting concrete, with the objective of enhancing its weak Interfacial Transition Zone (ITZ). The study examines the effects of various treatment methods for Rubber Aggregate (RA), such as NaOH, limestone filler, and crushed dune sand, on the mechanical properties of SCCR.In this paper the crushed dune sand and limestone filler were using as mineral addition in the formulation of self-compacting concrete (SCCR), for that a comparison was carried out on their effect on the properties and behavior of SCCR in a fresh and hardened state. The pre-treatment consequently allowed for improved compressive strength; results indicate an increase of 18.64% and 24.25% in the 28-day compressive strength, respectively, for the selected rubberized concrete mixture.

As cardiopatias congênitas são as mais frequentes entre as malformações congênitas, que, por sua vez, representam a segunda principal causa de mortalidade em crianças menores de um ano de idade em todo o mundo. Especialmente durante o período neonatal, que compreende os primeiros 28 dias de vida, a cirurgia cardíaca pediátrica demonstra benefícios notáveis para os pacientes com cardiopatia congênita. Historicamente, o tratamento dessas patologias tem sido desafiador, mas avanços significativos foram alcançados nas últimas décadas, principalmente na abordagem cirúrgica.  Com o crescente corpo de literatura sobre os avanços na cirurgia para correção de cardiopatias congênitas em recém-nascidos, foi possível realizar uma revisão integrativa de literatura por meio da plataforma PubMed. Essa revisão envolveu a seleção e análise criteriosa dos artigos, com o objetivo de revisar e analisar as evidências atuais sobre a cirurgia pediátrica e seu impacto nas cardiopatias congênitas em neonatos. Identificou-se que o reconhecimento rápido desses defeitos é importante devido à sua implicação prognóstica, devido à rápida deterioração clínica e alta mortalidade.  Além disso, os procedimentos minimamente invasivos, que antes eram uma visão futurista, agora são uma realidade palpável, oferecendo alternativas menos agressivas em comparação às cirurgias convencionais. Esses progressos resultaram em um aumento significativo na expectativa de vida das pessoas acometidas por esses agravos.

O objetivo deste trabalho é analisar o valor atribuído pelos alunos às aulas de educação física como meio para o conhecimento sobre as práticas esportivas, em comparação com outros meios, refletindo sobre as diferenças de gênero nessa avaliação. Os dados foram coletados mediante a aplicação de um questionário a 148 estudantes de três colégios da rede estadual de ensino do extremo noroeste do Paraná, sendo 83 do gênero masculino e 65 do gênero feminino. A análise está orientada por pressupostos da Teoria Crítica da Sociedade. Os dados expressam a superioridade das aulas de educação física para aprofundar o conhecimento sobre o esporte, em cotejamento com outros meios e instituições, sobretudo na avaliação das meninas. Há indícios de que a histórica associação entre o esporte e a força física e a virilidade, próprios de um modelo social marcado pela dominação e pelo controle dos indivíduos, justifique a tendência de as meninas atribuírem uma maior importância às aulas de educação física como um momento privilegiado de socialização de conhecimento esportivo.

The present study aimed to evaluate the antibacterial activity of aqueous extracts of Bidens sulphurea and Tanacetum vulgare L. against Staphylococcus spp. methicillin-resistant (mecA) isolates from the vaginal microbiota of pregnant women. Fifteen isolates of Staphylococcus spp. with the presence of the mecA gene, from the vaginal swabs of pregnant women, aged between 16 and 38 years, who underwent microbiological examination during the first trimester of pregnancy. The aqueous extracts of B. sulphurea and Tanacetum vulgare L. were obtained by infusion, as recommended by popular use, and then, the chemical identification of the extracts was performed by gas chromatography. The antibacterial activity of plant extracts was performed by the method of microdilution in broth. B. sulphurea extract had as major compounds: custonolide (8.06%), Isohumulene (6.19%), artemetin (21,13%), β-sitosterol (28.68%), phytol (7.36%) e 7,8-epoxylanostan-11-ol, 3-acetoxy- (7.09%). T. vulgare extract presented as the majority artemetin (13.38%), verrucarol (13.27%) and phytol (11.93%), ergosterol (5.43%), ethyl iso-allocholate (6.95%), 7,8-epoxylanostan-11-ol, 3-acetoxy- (14,46%), lycopene, 1,1',2,2'-tetrahydro-1,1'-dimethoxy-, all-trans (7.09%) e 9,19-cyclochloestene-3,7-diol, 4,14-dimethyl-, 3-acetate (8.58%). The isolates tested against aqueous extracts of B. sulphurea and T. vulgare L., obtained minimum inhibitory concentrations (MIC) between 1.17mg/mL and 37.5mg/mL, minimum bactericidal concentrations (MBC) of B. sulphurea varied between 75mg/mL and 150mg/mL, on the other hand, T. vulgare L. MBC had lower values ranging from 9.37mg/mL to 150mg/mL. It was confirmed the bactericidal and bacteriostatic activity of the tested extracts against isolates that have the mecA resistance gene, and it is possible to attest that these extracts are a therapeutic alternative.

Os implantes oculares biocompatíveis representam uma solução inovadora e promissora para o tratamento de uma ampla gama de patologias oftalmológicas, incluindo degeneração macular relacionada à idade, glaucoma, doenças da córnea e até retinopatia diabética. Este artigo revisa os principais avanços tecnológicos no desenvolvimento desses dispositivos, com foco na utilização de novos biomateriais, como polímeros biodegradáveis, hidrogéis e materiais híbridos, que favorecem uma melhor integração com os tecidos oculares. Tecnologias emergentes, como a nanotecnologia, a bioimpressão e a impressão 3D, também desempenham um papel crucial na criação de implantes mais eficazes, capazes de oferecer liberação controlada e prolongada de fármacos, além de permitirem a personalização anatômica de acordo com as necessidades do paciente. Essas inovações têm o potencial de melhorar os resultados terapêuticos, tornando os tratamentos menos invasivos e aumentando a longevidade dos dispositivos. No entanto, desafios significativos ainda persistem, incluindo os elevados custos de produção, questões regulatórias e a falta de padronização nos processos de fabricação, o que dificulta a ampla aplicação clínica desses implantes. Conclui-se que, apesar dos avanços notáveis, ainda são necessários mais estudos clínicos, maior desenvolvimento de tecnologias de fabricação em larga escala e estratégias que visem a redução de custos para tornar esses dispositivos mais acessíveis e viáveis para uma gama maior de pacientes.
