Published: February 2025

Rhabdomyosarcoma (RMS) is an uncommon soft tissue malignant tumor derived from striated muscle tissue. RMS is uncommon in the oral cavity. Herein, we reported the clinicopathological and immunohistochemical features of an RMS case in a 1-year-old female presenting clinically as an asymptomatic nodule on the lateral border of the tongue. The surgical excision of the lesion was performed. Morphologically, spindle cells with elongated nuclei and eosinophilic cytoplasm proliferation in a fascicular pattern was observed, with few tumor cells showing rhabdomyoblastic differentiation. Immunohistochemical analysis showed positivity to vimentin, muscle-specific actin, desmin, MyoD1, and myogenin. Ki-67 proliferation index was less than 10%. The final diagnosis was spindle cell RMS. The patient did not show signs of recurrence after twenty months of follow-up. Because of the unspecific clinical appearance, the clinical diagnosis of RMS is difficult. Therefore, careful histopathological and immunohistochemistry analysis of these tumors is essential for correct diagnosis and classification.

Wood density is the physical property directly related to the timber potential of a species and influences the environmental service of carbon storage and sequestration. Therefore, the objective of this study was to evaluate the wood density at different moisture levels (apparent, anhydrous, and basic) of the species Bertholletia excelsa, Dipteryx odorata, and Khaya grandifoliola in a young forest stand cultivated in an integrated crop-livestock-forest system. The Technological Reference Unit, established in 2010, highlighted the necessity for management interventions by 2021 to prevent excessive shading and eliminate phenotypically undesirable species. Material samples were harvested at five heights along the commercial stem to analyze wood density (anhydrous, apparent, and basic). Our results revealed that D. odorata had the highest densities (0.99, 0.91, and 0.83 g/cm3), while B. excelsa and K. grandifoliola displayed lower densities (0.68, 0.61, 0.55 g/cm3 and 0.61, 0.56, 0.51 g/cm3, respectively). Notably, D. odorata exhibited an increasing basic density from base to top, while K. grandifoliola demonstrated greater homogeneity along its stem. The presented results provide robust technical support to inform decision-making on the use of native and exotic species in integrated production systems, as well as emphasizing the potential of the crop-livestock-forest system as a sustainable production practice.

Social anxiety is currently considered a public health crisis, largely affecting several adolescents and young adults. The situation has caused worldwide concern due to the mental health of these individuals. The objective of this study is to establish the psychometric evidence of the Social Anxiety Scale in Peruvian university students. The type of study is instrumental and non-experimental. The subjects were 517 university students between the ages of 18 and 38 who participated in total (M = 20.7; SD = 2.50). The instrument used was the Marc Leary Social Anxiety Scale. The results are based on the statistical analysis of each item, through item-by-item testing and item-to-scale correlation, identifying values higher than .20. An analysis model was formed called the Confirmatory Factor Analysis (CFA), whose original dimensional model was carried out, finding inadequate fit indices, three items with low factorial weight, and correlated errors. A new CFA was conducted without these items and correlated errors, obtaining optimal fit indices for the new structure (χ²/gl = 2.48; CFI = .945; TLI = .939; RMSEA = .054). Regarding reliability, it was estimated with the omega coefficient (ω = .949). Lastly, scales and cut-off points were developed according to the sex of the subjects. In conclusion, the structure of the test was composed of 26 items, with two items, 24 and 28, being eliminated, making the test reliable for use based on its values.

Forecasting USD/INR Exchange Rates: A Time Series Approach Using ARIMA
Authors: Nirmala J.
Published: February 2025

This study aims to forecast the USD/INR foreign exchange rate employing the Autoregressive Integrated Moving Average model, analyzing its applicability over an extensive historical period from 1970 to 2024. The primary objective is to identify the most suitable model for predicting future exchange rate trends, which is crucial for investors and businesses engaged in international trade. Using 55 years of historical time series data, the ARIMA (2, 2, 0) model was identified as the most appropriate after rigorous testing and evaluation. The analysis revealed that the first and second autoregressive components (AR(1) and AR(2)) significantly enhanced the model’s predictive accuracy, while the moving average components were statistically insignificant. The forecast for 2025 to 2029 indicates an upward trend in the USD/INR exchange rate, suggesting a potential depreciation of the Indian Rupee against the US Dollar. These findings are highly relevant for financial analysts and investors, offering a reliable tool for decision-making and strategic planning in international finance. By applying the ARIMA model over an extended historical period, this study contributes to the literature with a robust forecast that can aid in risk management and future exchange rate assessments.

Market Development Potential of Flying Cars: An Analysis Based on Discrete Choice Model
Authors: Zheng Junyi
Published: February 2025

Electric flying cars, also known as electric vertical takeoff and landing aircraft (eVTOLs) are expected to play a transformational role in urban mobility. They can reduce traffic congestion, significantly enhancing transportation efficiency in populated areas such as big cities. Despite the great development potential of flying cars, their market size is largely unexplored, resulting in a large research gap. Research about market size and customer preference could justify the scale and potential of the flying car market, thereby helping companies’ market decisions, governments’ policymaking, and researchers’ R&D efforts. In this study, based on the data from New York taxi operations and the cost calculation of electric flying cars, we established a consumer discrete choice model, predicted the possibility of consumers choosing flying cars for transportation, and projected the market size of electric flying cars. The results show that 128,000 flying car missions are in demand, which further demonstrates the development potential for them. To improve the market size, advancements in battery technologies, well-established infrastructure, and highly efficient flying car operation management are required.

Research on Flood Prediction and Risk Assessment Based on Multiple Models and Entropy Weight Method
Authors: Shi Yupeng , Wu Peimeng , Qin Yu
Published: February 2025

The global water cycle under the combined influence of climate warming and economic development is the focus of international attention. Warming can cause melting glaciers and higher sea levels, and trigger extreme weather, increasing damage from flooding. Flood prediction and risk assessment have become the key to disaster prevention and mitigation work, requiring the influence of multiple factors. For this phenomenon, this paper establishes a mathematical analysis model to make reasonable planning and decisions to prevent economic losses and casualties caused by flood disasters. In this paper, we calculate the Spearman correlation coefficient using SPSS and train it using a classification algorithm. The CSV was divided into different categories, the weights of different indicators were obtained according to the entropy weight analysis, and the seven heaviest indicators were visualized with bar graphs. It was concluded that factors such as monsoon intensity, topographic drainage, and river management were unrelated to urbanization and agricultural practices. Then the flood prediction model based on entropy weight topography was preliminarily constructed and verified. By comparing the prediction results of the test set, the model's accuracy can be improved by drawing the error, and according to the requirements of the problem, five indicators are selected to build multiple linear regression and flood probability models. The flood prediction model is based on mathematical, physical principles and historical data, taking into account meteorological factors (such as rainfall, rainfall intensity, etc.), hydrology (such as river level, flow), terrain, soil, etc., to simulate and predict the future flood situation in a specific area. These models can help relevant departments and personnel to prepare for flood control in advance, formulate emergency measures, and optimize water resources management, to reduce the loss of life and property and social and economic impact caused by floods.

Authors: Huang Yiliang , Liu Yang , Wei Wenjian
Published: February 2025

Optimizing process parameters to control and improve steel strip hardness has become a critical concern for ensuring product quality and process stability in modern industrial production. This study firstly confirms the absence of missing values and performs descriptive statistical analysis. It is found that the strip thickness and width fluctuate between 8020 to 9570 and 180 to 234, respectively, while carbon and silicon contents show greater variability, ranging from 42 to 615 and 0 to 22. Among process parameters, leveler tension shows relatively minor fluctuations, while hardness ranges from 490 to 600, concentrated above 595. Through Pearson correlation analysis, carbon content, quench furnace temperature, strip speed, and thickness exhibit a strong positive correlation with hardness. In contrast, block cooler temperature, homogenizing furnace temperature, and heating furnace temperature show a significant negative correlation. Based on the results, this study suggests further process optimization to enhance the mechanical properties of the strip.

Published: February 2025

Since the advent of multifactor models, the identification of factors that could lead to abnormal returns and their portfolio implications has been the theme of consistent effort and study. Among these factors, the small-cap factor (SMB factor) is one of crucial importance. This paper provides an innovative approach to the evaluation of the SMB factor taking into consideration the time-series comparison of small and large caps under a high-frequency regime, identifying structural differences in terms of stochasticity and presence of jumps. The empirical results confirm the specificity of small caps, understood therefore as a diversifying asset class. Additionally, results fail to confirm abnormal returns in the sample, indicating that factor momentum shall be considered. Moreover, the paper demonstrates a framework for high-frequency statistics usage in investment evaluation.

Published: February 2025

Comics is a sequential art that appeals to a diversified audience, a medium of reflection on culture, society, and history. Graphic literature is a discourse of dynamic interaction of graphics in literature, including literary comics, graphic novels, sequential art, juxtaposed images, and other dimensions of visual and printed images. A Graphic novel is the collaborative medium of the interaction of word and image, visual and verbal imagery to create numerous meanings and multiple interpretations. The term Graphic medicine was coined by Ian Williams who is a doctor, comic artist, and writer; He defined Graphic Medicine as the intersection of the medium of comics and the discourse of healthcare. Graphic medicine analyzes and interprets the medium of comics which serves as an innovative platform for disturbing, risky, and taboo ideas of illness. Ian Williams’s graphic novel The Bad Doctor (2014) is a verbal and visual illustration of Obsessive Compulsive Disorder (OCD). The protagonist Ian a general practitioner tries to cope with his OCD, his obsessions are comically and satirically represented through the artistic medium of graphic narrative and iconography of illness.  Graphic Narrative of psychological illness like OCD by the sufferer of the illness gives a whole new perspective on the experience of psychological illness. Graphic narrative and iconographic representation of illness break down the traditional stereotypes of illness and give voice to the muted patient whose stories are unheard.

Infrastructure construction projects are considered highly susceptible to risks and uncertainties due to their complicated designs, sizes, functions and structural complexities. Among the different types of risks, the financial risks and the ability to manage them will have great implications for the cost performance of the relevant infrastructure projects. Therefore, high attention is paid to the financial risk management aspect of public infrastructure projects. In that concern, water supply infrastructure projects share several characteristics in common with other infrastructure construction projects while holding several other characteristics unique to themselves. Although many studies have been conducted on financial risk management in building and infrastructure projects, observed scanty of studies that address the financial risk management aspects of water supply projects in the Sri Lankan context. Therefore, this study is meant to fill significant void in terms of developing a financial risk management framework to address financial risk factors in Sri Lankan water supply projects. In carrying out this study, a mixed methodology was followed under an exploratory sequential design. Accordingly, the risk factors and risk management strategies identified in the reference literature were screened and shortlisted for their applicability in designing water supply projects in Sri Lanka and were validated through findings achieved at interviews with experts capable of highlighting new risk financial factors and strategies unique to the water supply projects in Sri Lanka. Subsequently, the risk factors and strategies identified in this process are mapped to develop a financial risk management framework for implementation of water supply projects in Sri Lanka in the future.

Essential oils are natural extracts known for their versatility, capturing widespread interest due to their diverse applications and the increasing consumer preference for safe and efficient health solutions. Their inherent natural properties make them valuable in various industries, including food, pharmaceuticals, agriculture, and textiles. In that respect, this research focuses on optimizing essential oil extraction using waste pomelo peels as the raw material. There two extraction methods, water distillation and Soxhlet, were employed to investigate the feasibility of utilizing pomelo peels for essential oil extraction. The main objectives that were meant to be achieved in this research included comparing the efficiency of water distillation and Soxhlet extraction methods, optimizing the essential oil extraction process by adjusting vital physical parameters, and determining the most effective pomelo peels. The waste pomelo peels required for oil extraction were collected around the Colombo district (Sri Lanka). Two distillation setups were used for water distillation: industrial-scale water distillation and lab-scale water distillation apparatus. The investigations revealed that Fresh-Grind pomelo peels exhibited notably higher efficiency for water distillation, with a yield of 0.8%. There the oil extraction yield for the industrial and laboratory extraction setup was reported as 0.5% and 0.8%, respectively. The Soxhlet experiments were conducted using various solvents: toluene, acetone, n-hexane, methanol and acetonitrile. However, based on the experiment results, n-hexane emerged as the most effective, yielding an efficiency of 7.1%. So, the Soxhlet extraction method was selected to optimize the process followed in essential oil extraction by waste pomelo peels.

Energy consumption analysis of a sensor node working in wireless sensor network
Authors: Khan Mohammad Asaduzzaman
Published: February 2025

The primary goal of this research work is to develop a close form energy consumption model of a sensor module working in a wireless sensor network. The energy consumption is an important aspect for a battery driven sensor node using in a wireless sensor network. The distinct feature of the proposed energy consumption model is to calculate the energy consumption for bit by bit data transfer of the sensor module. In existing literature there are many energy consumption models available but most of them have considered only one layer energy consumption. Instead of the existing model we have proposed a cross layer based energy consumption. Where together the physical layer and mac layer energy consumption are measured. The usefulness of our proposed energy consumption model is verified by calculation the node lifetime as well as network lifetime for various load in the network. We have also analysis our model with different multiple accesses techniques such as time-hopping (TH) and direct-sequence (DS) multiple access.  For reducing the energy utilization of a sensor module we have introduced the sleeping technique by which the sensor node will remain inactive where there is no data for sending to others.

HoQI - Low-noise Interferometric Sensors for the Future of Gravitational Wave Detectors
Authors:   , Mitchell Alexandra Louise
Published: February 2025

The perturbations in spacetime generated by the acceleration of massive objects propagate at the speed of light as waves, known as gravitational waves. The first detection of gravitational waves in 2015, and the many subsequent detections, have enabled unprecedented observations of the universe. These breakthroughs were made possible with decades of development of the terrestrial gravitational wave observatories LIGO and Virgo, which are sensitive enough to detect the minute effects of gravitational waves on Earth.

To further enhance the capabilities of these detectors and facilitate the observation of waves from more distant and massive sources, one key challenge must be addressed: low-frequency control noise. This noise arises from the control systems required to maintain detector functionality and sensitivity to gravitational waves. Reducing control noise and extending the detection bandwidth to 3,Hz as proposed for next-generation detectors like the Einstein Telescope, necessitates a reduction in the motion of the interferometer optics. This can be achieved by applying effective damping of the suspension modes through local sensing and control schemes, as well as by incorporating inertial rotation sensors to minimise tilt-coupling effects that limit current seismic isolation systems.

The homodyne quadrature interferometer (HoQI), a low-noise displacement sensor, is proposed as a potential solution to address the low-frequency sensitivity limitations. The maturity and technical readiness of HoQI will be demonstrated, with its application as a local sensor investigated and compared to existing sensors, showing significant reductions in optic motion. Additionally, HoQI’s suitability as a readout mechanism for inertial rotation sensors will be explored through two examples: OmniSens and the cylindrical rotation sensor.

This thesis shows the applicability and technical readiness of HoQIs for improving the low-frequency performance in current and future gravitational wave detectors.

Published: February 2025

In the contemporary world, since people are encountering environmental/climate issues and losing some species of ecosystem, world organizations have propounded ecosystem management to conserve the ecosystem for a wealthy future. Ecosystem management creates boundaries to reduce the extreme consumption of natural resources.  Nevertheless, the governments and people of the world fail to perform eco-management persistently. Therefore, the questions of what are the difficulties in implementing ecosystem management, despite the fact that eco-management has enough policies and plans and what is the strategy to increase the execution of ecosystem management among students through environmental education. Furthermore, no researcher has dealt with how teaching ecosystem management and environmental/climate fiction through ecosystem education raise robust awareness among students in society.  The objectives of the research paper are to describe how governments and industries neglect ecosystem management and prescribe eco-management and environmental fiction in environmental education. The research paper finds unaware of the apocalyptic future world nonexistence of an ecosystem causes the absence of ecosystem management among Homo sapiens.

Keywords: ecosystem, ecosystem management, environmental education, climate fiction, environmental fiction.

The relationship between rewards, recognition and motivation
Authors:   Professor & Head MBA  Institute of Aeronautical Engineering  , P Saisudha   P Saisudha  
Published: February 2025

A synthesis of rewards, recognition, and motivation promotes employee engagement and performance in different organizational contexts. The interrelationship of these different elements and how they influence productivity on individual and group levels have been covered in this paper. The intrinsic and extrinsic rewards are analyzed for their immediate effects on levels of motivation, while recognition is studied as an important external contributor to a workplace's value perception. The paper integrates literature reviews together with the psychological theories of motivation like Herzberg's Two-Factor Theory and Deci and Ryan's Self-Determination Theory to build a framework understanding of how rewards and recognition act as motivating factors intrinsically and extrinsically. Findings suggest that whereas extrinsic rewards often lead to short-term motivation, it is recognition that leads to long-term engagement and satisfaction. This research signifies the understanding of how purposefully used combinations of rewards and recognition will give maximum motivity to employees and contribute to improved organization productivity.
