Graph-Text Contrastive Learning of Inorganic Crystal Structure toward a Foundation Model of Inorganic Materials
Authors: Ozawa Keisuke , Suzuki Teppei , Tonogai Shunsuke , Itakura Tomoya
Published: April 2024

Developing foundation models for materials science has attracted attention. However, there is a lack of studies on inorganic materials due to the difficulty in the comprehensive representation of geometric concepts composing crystals: local atomic environments, their connections, and the global symmetries. We present a contrastive learning of inorganic crystal structure (CLICS) for embedding the geometric concepts, which contrasts texts representing the contextual patterns of geometries with the crystal graphs. We demonstrate that the geometric concepts are integrally embedded on the CLICS feature space, through experiments of concept retrieval from crystal graphs, similar structure search, and few-shot/imbalanced crystal structure classification.
MODELING THE IMPACT OF EXTERNAL RESERVES ON ECONOMIC GROWTH IN NIGERIA: AN APPLICATION OF AUTOREGRESSIVE DISTRIBUTED LAG
Authors: Ishaka Audu Jimoh , Adam Joseph Adavani
Published: April 2024

The article investigates the effect of foreign exchange reserves on Nigerian economic growth from 1970 and 2022. The methodology used to confirm the presence of a correlation between Nigeria’s external reserves and economic growth was the Autoregressive Distributed Lag Model Bounds Test and Error Correction Model. It was revealed that an increase in the gross domestic product was positively and significantly correlated with external reserve. The findings suggest that, over the long term, Nigeria’s external reserve, currency rate, export, import, and money supply all have a significant and beneficial impact on the country’s gross domestic product growth. However, during the study period, import, money supply, and export had more positive effects on GDP growth than external reserve and exchange rate. At a 5% level, the coefficients are statistically significant. These findings have a key consequence that external reserves are crucial for economic growth in Nigeria since they have a positive and significant link with both short- and long-term GDP growth. Given that these macroeconomic indicator variables have a large impact on GDP development, the government and other relevant organizations should develop policies that would help Nigeria increase its external reserve and achieve a stable and favorable exchange rate. Government, however, ought to concentrate on maximizing reserve building. As a result, optimal reserve is recommended in relation to the shocks the economy will experience and the debt’s existing value. The accumulation of reserves makes it necessary to pay for the importation of goods and services, infrastructural needs, agricultural needs, servicing of the country’s external debt, and financing domestic fiscal expenditure. As a result, optimal reserves will balance both economic growth and external reserves.

Published: April 2024

This study seeks to investigate the intricacies of strategic partnerships in the Fast-Moving Consumer Goods (FMCG) industry in Bangladesh. The research aims to explore the motivations, challenges, critical success factors, and implications of alliances in the fast-moving consumer goods (FMCG) industry. This will be done through 40 in-depth interviews with industry experts, managers, and executives from various FMCG companies. The study focuses on the rapidly changing and competitive market environment. The study utilizes qualitative analysis to reveal a notable transformation in the objectives and extent of strategic relationships. Originally centered on resolving issues related to distribution, alliances have progressed to include other goals such as innovation, market growth, and operational effectiveness. The motivations behind these agreements encompass risk reduction, consolidation of resources, market entry, and obtaining a competitive advantage. Nevertheless, fundamental difficulties were recognized, such as cultural gaps and opposing objectives among collaborating companies. To overcome these obstacles, it is necessary to implement strategic initiatives such as cultural integration programs, efficient communication techniques, and well-defined governance frameworks. The study’s conclusions are primarily constrained by its qualitative nature, which may impact its generalizability. Moreover, the emphasis on the Bangladeshi Fast-Moving Consumer Goods (FMCG) sector could restrict the wider repercussions for the industry. However, the results provide practical advice for FMCG companies, including solutions to overcome difficulties and improve the efficiency of strategic partnerships. Furthermore, the incorporation of sustainability and Corporate Social Responsibility (CSR) activities into these partnerships signifies a transition towards ethical corporate practices, which not only benefits business objectives but also contributes to the well-being of society. This study enhances the current body of knowledge by offering empirical observations on the changing characteristics, difficulties, and key determinants for success in strategic partnerships within Bangladesh’s FMCG industry. Nevertheless, the limitations encompass potential biases from participants and the inherent subjectivity in the qualitative research methodology.
EMPLOYEES’ JOB SATISFACTION USING HERZBERG’S TWO-FACTOR THEORY: EVIDENCE FROM THE FAST-FOOD RESTAURANTS IN PAGSANJAN, LAGUNA, PHILIPPINES
Authors: M. MACALINAO JOHN MATTHEW
Published: April 2024

Foods that can be quickly prepared are offered and served at quick-service restaurants. When time is limited and people are looking for meal options, these establishments offer the best solution. As a result, these establishments hire enough staff to guarantee smooth and effective operations. A recent survey by market research firm Clint revealed that close to 46% of Filipinos ate at fast restaurants one to three times a week on average. The fact that fast-food chains employed the greatest number of people in the fast-food industry suggested that this sector is the largest employer overall. This study sought to clarify the key elements of the method and identify and comprehend the variables that might affect the level of employees’ satisfaction. The study also looked into the relationship between job happiness and productivity. The conceptual framework for the study’s development and problem-solving procedure was Herzberg’s Two-Factor Theory. This theory was composed of two factors which argued that job satisfaction and dissatisfaction existed on two different continua, each with its factors. To gather the outcome of the administered research instrument, 147 respondents were requested to complete the checklist questionnaire. Participants were measured using a performance evaluation form to determine the relationship between fast-food employees’ job satisfaction and their performance. To ascertain the connection between job satisfaction and performance, discrepancies were categorized by demographic profile and then analyzed. The association between job satisfaction and demographic profile was shown to be correlated in a variety of ways, some of which were statistically different from others. Using a chi-square test, the relationship between job satisfaction and performance was investigated. The results showed a substantial correlation between the two variables. These results revealed whether or not the formulated hypothesis should be accepted.

A wideband smart antenna employing spatial signal processing
Authors: Uthansaku Monthippa , Bialkowski Marek E.
Published: April 2024

A smart antenna with capability of beam steeringin azimuth over a wide frequency band using only spatial sig-nal processing is presented. Filters and tapped-delay networksemployed in conventional wideband linear arrays are avoidedby using a two-dimensional rectangular array structure. Inthis array, only constant real-valued weighting coefficients, re-alized with amplifiers or attenuators, are used to form a de-sired radiation pattern. In order to estimate direction of ar-rival of a wideband signal, the MUSIC algorithm in conjunc-tion with an interpolated array technique is applied. In theinterpolated array technique, a composite covariance matrixis generated, which is a simple addition of covariance matricesof narrowband virtual arrays, being stretched or compressedversions of a nominal array. A working prototype of this wide-band array is presented. Its operation is assessed via full EMsimulations and measurements.
Building distributed ground station system with radio amateurs
Authors: Stolarski Marcin , Winiecki Wiesław
Published: April 2024

The paper concerns radio amateur satellites that are built by international student teams. For contacting a satellite, a single ground station is usually used. In this configuration and with the satellite on the low Earth orbit (LEO), teams have contact only for about 40 minutes per day. If the satellite has service for radio amateurs, they use it for 20 hours per day. A lot of them have connection to Internet. This is a big difference. In this paper, is shown how they can use the radio amateur transceivers and antenna systems in order to build ground stations network named distributed ground station system (DGSS). Frequencies, types of modulations, calculation of power budge, and the ways to control amateur stations by the Internet are also shown. These are essential procedures, because radio amateurs have their standards and habits. Finally a proposal of implementation dedicated DGSS system for radio amateurs with and without use of APRS network is put forward. Distributed ground station is one of the experiments on PW-Sat satellite, which is being build on the Warsaw University of Technology.
Review and perspective of high-k dielectrics on silicon
Authors: Hall Stephe , Buiu Octavian , Z. Mitrovic Ivona , Lu Yi , M. Davey William
Published: April 2024

The paper reviews recent work in the area of high-k dielectrics for application as the gate oxide in advanced MOSFETs. Following a review of relevant dielectric physics, we discuss challenges and issues relating to characterization of the dielectrics, which are compounded by electron trapping phenomena in the microsecond regime. Nearly all practical methods of preparation result in a thin interfacial layer generally of the form SiOx or a mixed oxide between Si and the high-k so that the extraction of the dielectric constant is complicated and values must be qualified by error analysis. The discussion is initially focussed on HfO2 but recognizing the propensity for crystallization of that material at modest temperatures, we discuss and review also, hafnia silicates and aluminates which have the potential for integration into a full CMOS process. The paper is concluded with a perspective on material contenders for the “end of road map” at the 22 nm node.

Authors: Kacprzak Przemysław , Kaleta Mariusz , Pałka Piotr , Smolira Kami , Toczyłowski Eugeniusz , Traczyk Tomasz
Published: April 2024

In the paper the market model for balancing communication bandwidth trade (BCBT) is analyzed in the form of multi-commodity market data model (M3). The distinguishing feature of BCBT model is that it assumes that market players can place buy offers not only for isolated network resources – inter-node links, but also for end-to-end network paths of predefined capacity, that is, every offer concerns a point-to-point bandwidth connection between a pair of specified locations in a communication network. The model enables effective balancing of sell and buy offers for network resources in a way which maximizes global economic welfare. The open multi-commodity market data model provides efficient and clear mechanisms, which support the environment of auctions and multi-commodity exchanges, especially when the trade is constrained by the infrastructure resources. Thus the model may be used in designing open information systems for market balancing and clearing in the context of multicommodity trade in various network infrastructure sectors.

The Integration, Analysis and Visualization of Sensor Data from Dispersed Wireless Sensor Network Systems Using the SWE Framework
Authors: Lee Yong Jin , Trevathan Jarrod , Atkinson Ian , Read Wayne
Published: April 2024

Wireless Sensor Networks (WSNs) have been used in numerous applications to remotely gather real-time data on important environmental parameters. There are several projects where WSNs are deployed in different locations and operate independently. Each deployment has its own models, encodings, and services for sensor data, and are integrated with different types of visualization/analysis tools based on individual project requirements. This makes it difficult to reuse these services for other WSN applications. A user/system is impeded by having to learn the models, encodings, and services of each system, and also must integrate/interoperate data from different data sources. Sensor Web Enablement (SWE) provides a set of standards (web service interfaces and data encoding/model specifications) to make sensor data publicly available on the web. This paper describes how the SWE framework can be extended to integrate disparate WSN systems and to support standardized access to sensor data. The proposed system also introduces a web-based data visualization and statistical analysis service for data stored in the Sensor Observation Service (SOS) by integrating open source technologies. A performance analysis is presented to show that the additional features have minimal impact on the system. Also some lessons learned through implementing SWE are discussed.

Published: April 2024

In this article the preconditioned conjugate gradient (PCG) method, realized on GPU and intended to solution of large finite element problems of structural mechanics, is considered. The mathematical formulation of problem results in solution of linear equation sets with sparse symmetrical positive definite matrices. The authors use incomplete Cholesky factorization by value approach, based on technique of sparse matrices, for creation of efficient preconditioning, which ensures a stable convergence for weakly conditioned problems mentioned above. The research focuses on realization of PCG solver on GPU with using of CUBLAS and CUSPARSE libraries. Taking into account a restricted amount of GPU core memory, the efficiency and reliability of GPU PCG solver are checked and these factors are compared with data obtained with using of CPU version of this solver, working on large amount of RAM. The real-life large problems, taken from SCAD Soft collection, are considered for such a comparison.
Link Quality and Energy Aware Geographical Routing in MANETs using Fuzzy Logics
Authors: Mishra Priya , Gandhi Charu , Singh Buddha
Published: April 2024

In literature, varieties of topology and geographical routing protocols have been proposed for routing in the MANETs. It is widely accepted that the geographical routings are a superior decision than topological routings. Majority of geographical routing protocols assume an ideal network model and choose the route that contains minimum number of hops. However, in reality, nodes have limited battery power and wireless links are additionally unreliable, so they may highly affect the routing procedure. Thus, for reliable data transmission, condition of the network such as link quality and residual energy must be considered. This paper aims to propose a novel multi-metric geographical routing protocol that considers both links-quality and energy metric along with progress metric to choose the next optimal node. The progress is determined by utilizing greedy as well as compass routing rather than pure greedy routing schemes. To combine these metrics, fuzzy logics are used to get the optimal result. Further, the protocol deals with “hole” problem and proposes a technique to overcome it. Simulations show that the proposed scheme performs better in terms of the packet delivery ratio, throughput and residual energy than other existing protocols.
Faster Point Scalar Multiplication on Short Weierstrass Elliptic Curves over Fp using Twisted Hessian Curves over Fp2
Authors: Wroński Michał
Published: April 2024

This article shows how to use fast Fp2 arithmetic and twisted Hessian curves to obtain faster point scalar multiplication on elliptic curve ESW in short Weierstrass form over Fp. It is assumed that p and #ESW(Fp) are different large primes, #E(Fq) denotes number of points on curve E over field Fq and #Et SW (Fp) Fp), where Et is twist of E, is divisible by 3. For example this method is suitable for two NIST curves over Fp: NIST P-224 and NIST P-256. The presented solution may be much faster than classic approach. Presented solution should also be resistant for side channel attacks and information about Y coordinate should not be lost (using for example Brier-Joye ladder such information may be lost). If coefficient A in equation of curve ESW : y2 =x3+Ax+B in short Weierstrass curve is not of special form, presented solution is up to 30% faster than classic approach. If A=−3, proposed method may be up to 24% faster.

Unsupervised Phoneme Segmentation Based on Main Energy Change for Arabic Speech
Authors: Lachachi Noureddine
Published: April 2024

In this paper, a new method for segmenting speech at the phoneme level is presented. For this purpose, author uses the short-time Fourier transform of the speech signal. The goal is to identify the locations of main energy changes in frequency over time, which can be described as phoneme boundaries. A frequency range analysis and search for energy changes in individual area is applied to obtain further precision to identify speech segments that carry out vowel and consonant segment confined in small number of narrow spectral areas. This method merely utilizes the power spectrum of the signal for segmentation. There is no need for any adaptation of the parameters or training for different speakers in advance. In addition, no transcript information, neither any prior linguistic knowledge about the phonemes is needed, or voiced/unvoiced decision making is required. Segmentation results with proposed method have been compared with a manual segmentation, and compared with three same kinds of segmentation methods. These results show that 81% of the boundaries are successfully identified. This research aims to improve the acoustic parameters for all the processing systems of the Arab speech.

Authors: Abbas Nasir , Raza Muhammad Ali , Paracha Zainab , Shahid Muhammad Sadiq
Published: April 2024

Purpose: This study examines the internal factors that are influencing profitability in Pakistani Islamic banks during the period 2016-2021.

Design/Methodology/Approach: The analysis utilizes panel data regression models to address potential estimation bias.

Findings: The study covers key Pakistani Islamic bank financial performance criteria. Internal factors significantly affect ROE and EPS. Gearing and capital ratios enhance ROE/EPS. Due to increased capitalization and leverage, Islamic banks' capital management is vital to profitability. ROE and NIM models are affected by deposits. Deposit funding drives Islamic bank profitability and interest income. In the NIM model, liquidity and NPL ratios affect ROE and EPS significantly. Asset quality and liquidity management effect interest income, not profits. Bank size does affect ROE and EPS models, which is notable in the findings. Islamic financial institutions can prioritize specialization and efficiency over expansion. These numbers indicate Pakistani Islamic banks' finances. Capitalization, leverage control, and deposit mobilization are key to financial success, while risk management ensures stability and profitability during economic downturns.

Implications/Originality/Value: The detailed investigation shows Pakistan's Islamic banking profitability. Deposit management, capital structure, and asset quality impact profitability. Capitalization and leverage improve earnings, therefore financial management matters. Deposit management is vital to profitability since it affects performance. Recession-sensitive Islamic banks show resiliency. NPA mitigation and liquidity management affect net interest margin, as a key driver. This research offers valuable insights for internal management strategies and regulatory frameworks aimed at enhancing the stability and growth of Islamic banking in the region.

El acelerado avance tecnológico de los últimos años ha impactado en una transformación sin precedentes en muchas áreas de la humanidad. La educación es una de ellas, en donde el auge de la Inteligencia Artificial (IA) es fundamental para el desarrollo de sistemas que permitan mejorar, cada vez más, la calidad de este servicio. En consecuencia, el propósito de la presente investigación es plasmar las generalidades acerca de los principales sistemas de Inteligencia Artificial usados para la personalización y predicción del rendimiento estudiantil. El enfoque metodológico de la investigación es una revisión bibliográfico – documental. De la revisión se desprende la importancia de los sistemas de IA para personalizar y predecir el rendimiento del estudiante los cuales, con un buen uso, puede ser una herramienta poderosa para mejorar la calidad de la educación. Los principales sistemas analizados para este tipo de funciones fueron los sistemas de tutores inteligentes, sistemas de análisis de datos educativos, sistemas de recomendación de cursos y sistemas de retroalimentación automática. Estos tipos de sistemas son capaces de analizar grandes cantidades de datos, en tiempo real, tales como: calificaciones, asistencia, participación y comportamiento, entre otros. Todo ello con la finalidad de identificar patrones y tendencias. La información recolectada y analizada le permite a esta tecnología personalizar la experiencia de aprendizaje para cada estudiante, proporcionando así recomendaciones y recursos adaptados a sus necesidades y habilidades individuales. Por otra parte, esta información sirve para predecir el rendimiento futuro de los estudiantes, lo que permite a los educadores intervenir tempranamente y brindar apoyo adicional a aquellos que puedan estar en riesgo de bajo rendimiento.

El presente estudio es el resultado de la planeación y ejecución de proyectos de vinculación con la sociedad, con la participación de estudiantes y docentes de la carrera Administración de Empresas de la Universidad Estatal del Sur de Manabí. Ante las necesidades detectadas entre los estudiantes se tuvo como objetivo realizar un diagnóstico que permita identificar las falencias dentro de la gestión administrativa por medio de la aplicación de las estrategias metodológicas y didácticas para mejorar el rendimiento en los beneficiarios directos del proyecto. A través de un enfoque metodológico mixto, se combinaron técnicas cuantitativas y cualitativas para analizar la situación actual y proponer recomendaciones, se llevó a cabo un estudio de campo que incluyó la recopilación de datos, la población estuvo constituida por miembros de 6 asociaciones. Las técnicas empleadas para respaldar este argumento fueron la encuesta y entrevista que se llevaron a cabo a través de un cuestionario con preguntas cerradas. Estos métodos ayudaron a identificar la matriz FODA, esta facilitó la determinación de factores clave para el desarrollo de las actividades. Los resultados del diagnóstico situacional revelaron áreas de mejora en la gestión administrativa, como la falta de capacitación en habilidades administrativas, la ineficiencia en la gestión de recursos, existen serias dificultades con la comunicación. Todo lo anterior justifica en que el enfoque proactivo no solo permite superar los obstáculos, sino también el liderazgo, la eficiencia operativa y la sostenibilidad de las asociaciones, contribuyendo así al desarrollo integral de la parroquia y el bienestar de sus habitantes.

Los marcadores moleculares y celulares en la leucemia linfoblástica aguda (LLA) son clave para entender, diagnosticar y tratar esta enfermedad. Permiten identificar subgrupos de pacientes con diferentes perfiles biológicos, lo que mejora la estratificación del riesgo y la personalización del tratamiento. La presente investigación se realizó bajo una metodología de revisión bibliográfica sobre marcadores moleculares y celulares en la leucemia linfoblástica aguda (LLA) se llevó a cabo mediante una exhaustiva búsqueda de artículos científicos en bases de datos como PubMed, Scopus y Web of Science. La detección de fusiones génicas y mutaciones específicas ha llevado al desarrollo de terapias dirigidas, como imatinib para la fusión BCR-ABL, mejorando los resultados clínicos. Sin embargo, persisten desafíos en la traducción clínica de estos avances, como la complejidad genética y la resistencia a la terapia. Se necesita investigación continua para identificar marcadores más precisos y desarrollar terapias más efectivas y personalizadas, con el objetivo de mejorar los resultados y la calidad de vida de los pacientes con LLA.
