Changing Your Mind: Creating Tangibility in Neural circuits in Order to Increase Neurotechnological Efficacy
Authors: Karthikeyan Hasita
Published: February 2024

Neuroscience is an ever evolving field that grows each day. It has branched into many different fields of study but a novel area of research is neurological technology (Neurotechnology). Neurotechnology has enabled for victims of various neurological disorders to manage their symptoms and lead normal lifestyles. But how can one improve neurotechnology? Like any device there is always a better model, a more efficient one. The body doesn’t need help healing itself but neurotechnology can help. Another question one could ask is how does the body’s ability to heal itself help neurotechnology?Given the dynamic nature of neurotechnology, anything that can support it will work to boost the technology's advantages. Therefore, integrating the old and modern can only lead to great results, and the little drawbacks and side effects may be overlooked due to the collaboration's immense value. In conclusion, neuroplasticity is a factor that may have an impact on how effective neurotechnologies are. It should be taken into account while creating new kinds of instruments, and treatment strategies should take the variability this association brings into account.

Authors: Khokhar Reeva , Appavu Rajagopal
Published: February 2024

Uveal Melanoma is the most common primary intraocular cancer and it affects thousands of individuals on an annual basis. Although uveal melanoma is rarer than other cancers it is very aggressive and can be extremely deadly, since in nearly half of all uveal melanoma cases the cancer ends up spreading to other parts of the body. With such a large chance of metastasis occurring in uveal melanoma cases, it is essential to discover effective ways to track the metastasis of uveal melanoma and treat the patients before the cancer has spread too far in the body. This paper first explains what uveal melanoma is and how it occurs and progresses throughout the body. Then, it discusses some novel biomarkers introduced by recent studies and highlights the way these biomarkers can offer a means of improved prognostication as well as help guide more effective personalized treatments for uveal melanoma patients.

Authors: Park Elain , Maddirala Satya , Eckert Paul
Published: February 2024

The current state of metaverse implementation within the marketing industry is gaining popularity as reachable technologies and visions for the metaverse are created, media coverage on the topic becomes widespread, and the demand for the metaverse increases due to the influence of recent world events. The future possibilities and opportunities of the metaverse as the next revolutionary platform after the internet makes the metaverse an increasingly important topic for retailers and businesses. Due to the unique characteristics of a metaverse, a platform which incorporates both the virtual and physical aspects of retail, marketers should create a marketing strategy in the metaverse oriented around a “retail theater” experience for consumers. Using a retail theater, marketers will be able to attract consumers to their metaverse store, by allowing them to have a unique and enjoyable shopping experience. A deep understanding of consumer preference of the target market in the metaverse is necessary in order to increase consumer adoption of the new interface technology and to compensate for  factors of consumer dissatisfaction regarding the current retail environment. The current paper aims to review and connect the literature regarding retail and the metaverse through deductive content analysis and research. By means of building upon and connecting literature regarding the metaverse and marketing communications, the paper proposes an effective marketing strategy in the metaverse for businesses. The proposed strategy may serve as a framework for future research as well as a guide for marketing professionals looking to expand retail into the metaverse platform.
Effects of Timing on the Efficacy of Stem Cell Transplantation after Acute Myocardial Infarction
Authors: Monteiro Giovanna , Ingram Catherine
Published: February 2024

Acute myocardial infarction (AMI) is the blocking of coronary arteries that prevents oxygenated blood from reaching the heart tissues, resulting in damage to the myocardium and affecting heart function. This condition affects millions of people every year and is detrimental to their quality of life. Several clinical trials have investigated the efficacy of using bone marrow-derived stem cells (BMSCs) to improve heart function after AMIs. However, different variables could impact the results of the trials, one of them being the injection time of cell therapy after reperfusion. This paper aims to investigate the short-term effects of timing on the efficacy of bone marrow-derived mononuclear cell transplantation after acute myocardial infarction. A systematic literature search of PUBMED, EMBASE, European Society of Cardiology, and American Heart Association databases was made on randomized controlled trials with at least 3-month follow-up data for patients with AMI undergoing percutaneous coronary intervention (PCI) and receiving intracoronary autologous BMSC transfer subsequently. A total of 12 trials with 1061 patients were selected for analysis. Compared to baseline level, BMSC transfer within 24 hours of PCI significantly improved left ventricular ejection fraction (LVEF; 3.44% increase, 95% confidence interval [CI]: 2.20%-4.68%, P< 0.00001). The “3-7 days after PCI” subgroup also showed notable improvements in LVEF (LVEF; 2.52% increase, 95% confidence interval [CI]: 1.01%-4.04%, P = 0.001). However, in the subgroups that received BMSC transplantation either 7-14 days after PCI or later than 15 days after PCI, there was no significant effect on treatment outcome.

Authors: Park Sungju , Cho Hyunseo , Chung Ahyoung , Han Timothy , Yi Taeoh , Paik Angela , Lee Taeheon
Published: February 2024

Chest X-ray imaging is a widely used diagnostic tool for the detection and classification of various lung diseases. In this study, we propose a methodology to enhance the classification accuracy of chest X-ray images by leveraging machine learning techniques. Specifically, we employ the VGG-19 architecture to classify chest X-ray images into five distinct lung conditions: normal, tuberculosis, COVID-19, lung opacity, and pneumonia. A comprehensive dataset consisting of 31,787 chest X-ray images sourced from multiple medical institutions and hospitals worldwide is collected. Each image is labeled by expert radiologists with one of the five lung conditions. The dataset is then preprocessed and trained with 30 epochs. The trained VGGnet model achieved overall test accuracy of 95.11%, demonstrating its capability to accurately classify chest X-ray images into the five targeted lung conditions. The proposed methodology holds significant potential for improving the efficiency and accuracy of lung disease diagnosis based on chest X-ray images. By employing machine learning techniques, we can automate the classification process, providing clinicians with valuable decision support and expediting treatment plans. Moreover, the developed model can assist in the identification of lung diseases, including critical conditions such as COVID-19, enabling prompt and effective patient management.

Published: February 2024

This research investigates the impact of auditor’s independence on earnings management in listed deposit money banks in Nigeria. Utilizing a correlational research design, the study explores the relationships between auditors’ independence, measured by audit firm specialization, audit fee, and audit firm size, and earnings management, proxied by accrued earnings. Secondary data from the annual reports and accounts of twelve selected banks over ten years (2013-2022) were analyzed using fixed effect estimation. The findings reveal that audit fee, audit size, and audit tenure positively influence earnings management. The positive coefficients suggest that higher audit fees, larger audit sizes, and longer audit tenures are associated with increased discretionary accruals. However, non-significant p-values caution against accepting these associations at the 5% level. The coefficient of determination (R2) indicates that the chosen variables collectively explain 27.26% of earnings management, offering some explanatory power to the model. In conclusion, the study recommends listed deposit money banks to prioritize engagement with Big 4 Audit Firms and carefully consider audit fee structures. Regulatory bodies, particularly the Central Bank of Nigeria, are advised to enhance surveillance, particularly in the realm of auditor remunerations. The research underscores the need for caution in interpreting the identified associations and highlights avenues for future research, including incorporating control variables and addressing potential endogeneity concerns for a more nuanced understanding of the relationship.

Authors: Ayako Lornah Irene
Published: February 2024

Kenyan Sign Language is a vital language for the Deaf community in Kenya and plays a pivotal role in their communication and education. This study investigates the appropriateness of including hearing students in the Kenyan Certificate of Secondary Education (KCSE) Kenyan Sign Language (KSL) examination, originally designed and adapted for deaf students. The research employed a qualitative approach, exploratory design and drawn upon the foundation of Critical Pedagogy. Purposive sampling was used to select seven(7) participants who are teachers of KSL and have experience in teaching both the hearing and deaf learners. Data was collected through interviews and analyzed thematically. The study findings underscore the need for a comprehensive reassessment of the KSL examination, considering the linguistic diversity and cognitive abilities of both deaf and hearing learners. The suggested strategies aim to create a more inclusive and equitable assessment system that respects the unique needs of each group, fostering a fair and accurate evaluation of their proficiency in Kenyan Sign Language. The researcher firmly recommends the exclusion of regular learners from KSL, KCSE examinations administered by the Kenya National Examination Council. Citing the tailored nature of the current 8-4-4 system’s Kenyan Sign Language (KSL) curriculum and exams for deaf students, the proposal emphasizes that regular students desiring to acquire KSL skills could opt for extracurricular KSL club participation.

Published: February 2024

Dalam ekonomi Islam, bisnis dan etika tidak harus dipandang sebagai dua hal yang bertentangan, sebab, bisnis yang merupakan simbol dari urusan duniawi juga dianggap sebagai integral dari hal-hal yang bersifat investasi akhirat. Artinya, jika orientasi bisnis dan upaya investasi akhirat diniatkan sebagai ibadah dan merupakan totalitas kepatuhan kepada Tuhan, maka bisnis dengan sendirinya harus sejalan dengan kaidah-kiadah moral yang berlandasan keimanan kepada akhirat. Bahkan dalam Islam, pengetian bisnis tidak di batasi dengan urusan dunia saja, tetapi mencakup seluruh kegiatan di dunia yang dibisniskan diniatkan sebagai ibadah untuk meraih keuntungan atau pahala akhirat.

Tout-Monde
Authors: Chanson Philippe
Published: February 2024

"All-World" is a conceptual tool put forward by Martinique philosopher Édouard Glissant, through which he proposes to rethink our erratic world and our presence in it, overcoming the ideologies of borders, ghettos and globalization against all forms of standardization that trivialize differences. This way of thinking recognizes the interconnections, entanglements and interdependencies of cultures and individuals generated by an irresistible and unpredictable process of creolization. It advocates the vision of a totality-world in all its diversity and excesses, to desire it, to dream it and to live it in the poetics of Relation, through the imaginary and in a form of rooted wandering that allows us to venture beyond our only place without getting lost.
Word Sense Disambiguation applied to Assamese-Hindi Bilingual Statistical Machine Translation
Authors: Barman Anup Kumar , Sarmah Jumi , Basimatary Subungshri , Nag Amitava
Published: February 2024

Word Sense Disambiguation (WSD) is concerned with automatically assigning the appropriate sense to an ambiguous word. WSD is an important task and plays a crucial role in many Natural Language Processing (NLP) applications. A Statistical Machine Translation (SMT) system translates a source into a target language based on phrase-based statistical translation. MT plays a crucial role in a WSD system, as a source language word may be associated with multiple translations in the target language. This study aims to apply WSD to the input of the MT system to enhance the disambiguation output. Hindi WordNet was used by selecting the most frequent synonym to obtain the most accurate translation. This study also compared Naïve Bayes (NB) and Decision Tree (DT) to test and build a WSD model. NB was more appropriate for the WSD task than DT when evaluated in the Weka machine learning toolkit. To the best of our knowledge, no such work has been carried out yet for the Assamese Indo-Aryan language. The applied WSD achieved better results than the baseline MT system without embedding the WSD module. The results were analyzed by linguist scholars. Furthermore, the Assamese-Hindi transliteration system was merged with the baseline MT system for the translation of proper nouns. This study marks a remarkable contribution to Assamese NLP, which is a low computationally aware Indian language.
Modeling and Simulation of a Renewable Energy PV/PEM with Green Hydrogen Storage
Authors: Hidouri Dalila , Marouani Rym , Cherif Adnen
Published: February 2024

The introduction of green hydrogen-based energy storage in association with renewable energy constitutes a promising and sustainable solution to the increase in energy demand while reducing greenhouse gas emissions. However, these hybrid systems face technical, economic, and logistic challenges that require a new transport and distribution architecture. The technical-economic study of these expensive installations requires good modeling and optimal sizing of the system components. This study presents a global model for hydrogen production and storage stations using photovoltaics (PV) and integrating Proton Exchange Membrane Fuel Cell (PEMFC) modules for electric vehicles. The simulations and sizing were based on the implementation of an effective mathematical model capable of accurately simulating the real dynamic behavior of the installation, the electrical and energy yields, the power consumed and produced, and finally the mass of hydrogen stored and/or consumed by the fuel cell. In this model, the hybrid system integrates PV solar panels with a maximum power of 1.2 MW, followed by a 1.0 MW Proton Exchange Membrane (PEM) electrolyzer, a high-pressure hydrogen storage tank, and a PEMFC to convert hydrogen into electricity. The simulation results showed that the energy generated by the PV panels can produce around 200 kg/day of green hydrogen by electrolysis, which makes it possible to power 100 electric cars per day with a range of 250 km for each.

Authors: Saqib Malik Najmus , Dawood Hussain , Alghamdi Ahmed , Dawood Hassan
Published: February 2024

Blind image deblurring aims to recover an output latent image and a blur kernel from a given blurred image. Kernel estimation is a significant step in blind image deblurring and requires a regularization technique to minimize the cost function and the edges of objects to generate a sharp image in a better way. This study proposes a new image regularization technique called Weber's Law Regularization (WLR) based on the Weber law phenomenon. The Weber ratio was used to preserve the edges of small salient objects and to minimize the cost function to obtain a sharp image while minimizing the ringing effect. To validate the WLR, experiments were conducted on benchmark synthetic and real word images and compared with existing state-of-the-art methods. The experimental results showed that WLR can effectively and efficiently deblur images even in the absence of prior knowledge.

Authors: Schiopu Adriana-Gabriela , Girish Bhujang Mutt , Satish Bhujang Mutt , Shubha Shivanandamurthy
Published: February 2024

The current study intends to examine how forging under hot conditions affects wear characteristics of tungsten carbide (WC) particles reinforced aluminum alloy 6061 composites. The reduction ratios of 20%, 40%, and 60% were employed during forging, and the percentages of reinforcement used were 0, 2, 4, and 6 (weight fractions). The investigation clearly showed that the forged composites had a substantially lower wear rate than the unforged composites. It was discovered that the wear behavior of the composite improved due to the higher content of WC particles present in the matrix. Enhanced wear rate was observed as the weight and sliding distance increased.
The Effect of Kevlar Fibers on the Mechanical Properties of Lightweight Perlite Concrete
Authors: Al-Daraji Mohammed , Aljalawi Nada
Published: February 2024

Fiber-reinforced concrete contains a fibrous material that increases its structural cohesion. The use of separate short fibers distributed in a random direction improves the strength of Lightweight Concrete (LWC) without exceeding its upper-density limit, improving its high fragility and mechanical properties compared to Natural-Weight Concrete (NWC). This study investigated the effect of adding Kevlar 49 fibers with three percentages of cement weight, 0.5, 1, and 1.5%, on the workability, dry density, and tensile and compressive strength of LWC. The use of Kevlar fibers in different proportions improves mechanical properties, significantly increases durability, and reduces the workability of LWC. The increase in compressive strength when adding 0.5% fibers was 19 and 15% and when adding 1% was 10 and 6%, after 7 and 28 days, respectively. At 1.5%, after 7 and 28 days, there was a decrease in compressive strength due to fiber agglomeration. Additionally, increasing the fiber dose from the optimal value caused a sharp decrease in workability by 37-40%.

The changing social structure of Uttarakhand
Authors: Negi Bhal Chandra Singh
Published: February 2024

The impact of geographical disparities on social groups residing in a specific area greatly influences the cohesion of the community. The social customs, traditions, societal structure, values, festivals, celebrations, and daily activities of the inhabitants of that region are broadly influenced by these geographical variations. As a result, different social landscapes develop and evolve in each region due to the geographical features. This is because physical conditions on the ground start to change as they move from one place to another. Therefore, as a result of the interaction between humans and nature, developed social landscapes also change along with the natural environment, leading to changes in human settlement and their way of life in a particular area. As a result of modern development, significant changes are becoming evident in various aspects such as local communities, local cultural traditions, family structures, rural social systems, marriage customs, inheritance practices, and so on. Over centuries, not only has the region integrated into the mainstream of the nation's flow but also actively participated in the nation's development.

The prevailing research inadequately explores the pragmatic strategies within courtroom discourse, particularly in non-Western legal systems such as Indonesia. This study embarks on bridging this gap by analyzing pragmatic strategies employed in Ferdy Sambo's plea within the Indonesian legal environment. Utilizing qualitative methods encompassing discourse and pragmatic analysis, this study scrutinizes the deployment of linguistic techniques and pragmatic strategies to meet communicative objectives. The investigation unveils a meticulous utilization of assertive and declarative illocutionary acts, demonstrating a narrative woven with assertiveness, seeking validation and empathy in the claustrophobic courtroom atmosphere. Furthermore, it revealed the significance of understanding the intricate relationship between societal norms, values, and the narrative crafted within a plea, especially in culturally rich contexts like Indonesia. This endeavor enhances the comprehension of the pragmatic strategies in Ferdy Sambo's plea and delineates the broader societal influences that dictate the narrative dynamics within the Indonesian legal discourse. Through this lens, the study contributes substantially to pragmatics, discourse analysis, and legal communication, inviting further nuanced research.

Background: The elderly are individuals who experience a slow ageing process that can cause a decrease in physical function and condition. A noticeable decrease in function in the elderly is a decrease in muscle mass. This study aimed to determine the relationship between leg muscle strength and functional mobility ability in the elderly. This study aimed to determine the relationship between leg muscle strength and functional mobility in the elderly.

Methods: The design of this study was observational analytic with a cross-sectional study direction. At the research site at Puskesmas II Tabanan, the number of research subjects was 63 older people aged 60-69 years. A 30-second chair stand test measures leg muscle strength, while a timed up-and-go test measures functional mobility ability.

Results: The results of the association test using Spearman's Rho Test obtained a correlation coefficient value (r) -0.535 with a p-value=0.000 (p<0.05), which means there is a strong significant relationship that is negative in both variables.

Conclusion: There was a strong negative significant relationship between leg muscle strength and functional mobility ability in the elderly at Puskesmas II Tabanan.
Fusiones y adquisiciones

Una operación de adquisición o de fusión descansa sobre el valor que cada una de las partes le ha asignado a la sociedad objetivo (o a las sociedades participan­tes) y su capacidad para producir ingresos en el futuro. Sin embargo, la debida valoración y el mantenimiento del valor no resultan sencillos al tener en cuenta la asimetría informativa y la incertidumbre que acompaña al proceso. El presente libro se orienta al estudio, desde una perspectiva funcional, de tres instrumentos empleados en la práctica negocial para superar (o por lo menos atenuar) estos problemas: (1) El due diligence, (2) las declaraciones y garantías y (3) las cláusulas MAC.

The design and fabrication of a low-speed wind tunnel (LSWT), which is a critical component for testing and comprehending aircraft aerodynamics, is presented in this study. Despite the increasing prominence of computational fluid dynamics (CFDs) in manufacturing engineering, wind tunnels remain essential for the intricate development of aircraft and automobile designs with complex flow interactions. Using SolidWorks, we focused on controlling flow turbulence approaching the test section, emphasizing performance and quality parameters. The construction of the wind tunnel used plywood with an axial fan regulating the airspeed, and Arduino facilitated data acquisition. The drag and lift on the Y Clerk Airfoil were quantified by two load cells along the XY-axis, complemented by a Pitot Static Tube and a multitube inclined plane manometer for pressure and velocity calculation. Fusion 360 simulation software was used to analyze pressure and velocity profiles at speeds ranging from 10 to 20 m/s, providing a comprehensive quantitative evaluation of the wind tunnel’s capabilities. By emphasizing both design innovation and quantitative performance metrics, this study underscores the continuing significance of wind tunnels in engineering.
Ozone and aerosol optical depth retrievals using the ultraviolet multi-filter rotating shadow-band radiometer
Authors: Michalsky Joseph , McConville Glen
Published: February 2024

Abstract. The ultraviolet multi-filter rotating shadow-band radiometer (UV-MFRSR) is a seven-channel radiometer with narrowband filters centered between wavelengths 300 and 368 nm. Four of the middle wavelengths in this device are near those used in the Dobson spectrometer to retrieve ozone column abundance. In this paper measurements from Mauna Loa Observatory (MLO) were used first to calibrate the instrument using the Langley plot method and subsequently to derive column ozone and aerosol optical depths. The ozone derived from the UV-MFRSR was compared to the ozone measured by a Dobson spectrophotometer that operates daily at the MLO, resulting in column values within about 1 DU on average for 43 d in 2018. The aerosol optical depth (AOD) retrievals are more challenging. Generally, the AOD increases with wavelength between 305 and 332 nm, not what is expected given the typical AOD wavelength dependence at visible wavelengths. An example of this behavior is discussed, and research by others is cited that indicates similar behavior at these wavelengths, at least for the low-aerosol-optical-depth conditions encountered at high-altitude sites.
Technical note: Retrieval of the supercooled liquid fraction in mixed-phase clouds from Himawari-8 observations

Abstract. The supercooled liquid fraction (SLF) in mixed-phase clouds (MPCs) is an essential variable of cloud microphysical processes and climate sensitivity. However, SLF is currently calculated in spaceborne remote sensing only as the cloud phase frequency ratio of adjacent pixels, which results in a loss of the original resolution in observations of cloud liquid or ice content within MPCs. Here, we present a novel method for retrieving the SLF in MPCs based on the differences in radiative properties of supercooled liquid droplets and ice particles at visible and shortwave‐infrared channels of the geostationary Himawari-8. Liquid and ice water paths are inferred by assuming that clouds are composed of only liquid or ice, with the real cloud water path (CWP) expressed as a combination of these two water paths (SLF and 1-SLF as coefficients), and SLF is determined by referring to the CWP from CALIPSO. The statistical relatively small cloud phase spatial inhomogeneity in Himawari-8-pixel level indicates an optimal scene for the cloud retrieval. The SLF results are comparable to global SLF distributions observed by active instruments, particularly for single-layered cloud systems. While accessing the method’s feasibility, SLF averages are estimated between 74 % and 78 % in Southern Ocean stratocumulus across seasons, contrasting with a range of 29 % to 32 % in Northeast Asia. The former exhibits a minimum SLF around midday in summer and a maximum in winter, while the latter trend differs. This novel algorithm will be valuable for research to track the evolution of MPCs and constrain the related climate impact.
