Rhetoric Ambiguity: A Pragmatic Study on Selected Poetic Excerpts
Authors: Salem Rami Jamil
Published: October 2023

Objectives: The study aimed to investigate the rhetoric ambiguity which results from the semantic senses that morphologically similar words have and analyzes some selected poetic excerpts rhetorically and pragmatically.

Methods: A descriptive-analytical approach was used to achieve the aim of the study; by applying the mechanisms of pragmatic theory to uncover the implicit meanings and the deep structure of poetry. Thus, the study analyzes these excerpts in light of the speech acts theory, the implicature theory, the conversational implicature, and contextuality. The study covers two frameworks: a theoretical one in which we define rhetoric ambiguity, and a procedural one in which some poetic examples are analyzed.

Results: The findings indicated that pragmatics is very effective for analyzing the poetic examples, and for uncovering the implicit meanings and the deep structure of poetry, especially in the case of elliptical ambiguity. Moreover, metaphor types that encompass ambiguity differ according to the context. Finally, the study also found that there are rhetorical purposes and implicatures that are determined according to the speech acts in light of the rhetoric ambiguity.

Conclusions: The study recommended carrying out more research about the field of Arabic rhetoric according to the data of new rhetoric (the argument theory). It also recommends casting light on the old rhetoric terms and involoves convincing objectives that make it possible to study and testify according to the argument and pragmatic theories

Authors: Nawayseh Abeer Jarad , Adayleh Mohammad Ibrahim
Published: October 2023

Objectives: The aim of this study is to unveil the vision and imagery of pre-Islamic poetry about death and immortality and how pre-Islamic poets expressed this phenomenon in their poetry. This is explored based on the vision of the nature of death, and thoughts and myths related to it, in the view of pre-Islamic people.

Methods: The study followed the descriptive-analytical approach in tracking the idea of death and immortality in the poetry of the pre-Islamic era.                                                                                   

Results: It was found that the pre-Islamic poet held certain belief about death as an absolute destiny. Also, pre-Islamic poetry showed connections with pre-Islamic religious beliefs, hence, it represents their faith of the idea of recreation and reckoning. In addition, there can be noticed a representation of ancient burial ritual of the Arabs, and the cases of individual and collective death.This poetry also indicated an attempt to find ways to confront death and achieve immortality.

Conclusions: Researchers in the future should give the duality of death and mortality the necessary attention and identify it as a prominent phenomenon in pre-Islamic poetry in particular and Arab poetry in general. This phenomenon (the duality of death and mortality) can be traced in the classical Arabic books. The subject needs a variety of studies analyzing the aspects of death and the other phenomena emerged in this poetry at that time

Impact of recycled aggregate brick on the physical-mechanical and environmental characteristics of cement treated bases
Authors: Toumi Youcef , Mezhoud Samy , Boukendakdji Otmane , Hadjadj Moussa
Published: October 2023

Recycled aggregate brick (RAB) constitutes a significant waste stream in developed countries, originating from brick manufacturing and demolition processes. This paper investigates the potential utilization of various sizes of RAB as replacements for natural aggregate (NA) in cement-treated bases (CTB), along with an assessment of their mechanical and environmental properties. The study includes a life cycle analysis to evaluate the environmental impacts of different CTB formulations. The novelty of this study lies in the environmental evaluation of four types of CTB, including natural, recycled, and mixed CTB. The physical and mechanical properties of the recycled brick and natural materials are characterized and compared. Results indicate that recycled brick aggregates, when combined with a cement mixture, can be used as a base and sub-base layer with good mechanical performance. Moreover, environmental analyses demonstrate that recycled aggregate generates fewer impacts than natural aggregates. Consequently, this study suggests that the utilization of recycled aggregates brick in CTB offers a sustainable waste management solution while simultaneously contributing to the reduction of environmental impacts associated with construction activities.
Surface properties of an InGaZnO4 layer with a monolayer formed using a phosphonic acid: wettability, work function, and thermal stability
Authors: Kitano Yudai , Hattori Yoshiaki , Kitamura Masatoshi
Published: October 2023

The surface properties of an InGaZnO4 (IGZO) layer with a monolayer formed on the surface using octadecyl phosphonic acid (ODPA) or (1H, 1H, 2H, 2H-heptadecafluorodecyl) phosphonic acid (FDPA) were investigated. Surface roughness, wettability, and work function were investigated using atomic force microscopy, water contact angle measurement, and photoelectron yield spectroscopy, respectively. The reaction time of monolayer formation on an IGZO layer was discussed based on the measured contact angle. An ODPA-monolayer formed at a slightly higher rate than an FDPA-monolayer. The work function measurement provided an estimate of the density of the molecule in the monolayer. Furthermore, the measured contact angle was used to evaluate the thermal stability of a monolayer. The evaluation suggested that annealing above 500 K causes monolayer desorption for both ODPA- and FDPA-monolayers.

Authors: Santos Rojas María Isabel , Alarcón Barcia Alda Noelia , Gruezo Montesdeoca Karla Lissette
Published: October 2023

La erosión dental corresponde a la pérdida irreversible de la superficie dental por la acción química de los ácidos, donde las bacterias no interfieren. Las lesiones erosivas se caracterizan clínicamente por una superficie lisa, opaca y transparente, un contorno de esmalte intacto en el margen gingival, pérdida de la morfología dental, presencia de depresiones superficiales y caries, y en casos severos afectan la dentina y la pulpa dental. Uno de sus factores etiológicos son los hábitos alimentarios, puesto que los ácidos de los alimentos son precursores para la erosión dental. El objetivo del presente estudio fue determinar la relación existente entre los hábitos alimentarios y la erosión dental. Se realizó una revisión sistemática, empleando como fuentes de información la SciELO, Redalyc, Medigraphic, PubMed, ResearchGate, y el metabuscador Google Académico, de los trabajos publicados entre el 2017-2021. La búsqueda estuvo basada en el estudio de las variables: erosión dental; corrosión dental, hábitos alimentarios; tratamiento y prevención de la erosión dental. Se pudo determinar que la relación entre los hábitos alimentarios y la erosión dental se debe a la acidez de los alimentos, el ácido es la principal causa de erosión y la posibilidad de erosión aumenta con la frecuencia de su ingesta. El conocimiento de los alimentos causantes de la patología garantiza una prevención directa y evita la ejecución de tratamientos invasivos.

Authors: Calcagno Alessandra , Coelli Stefania , Corda Martina , Temporiti Federico , Gatti Roberto , Galli Manuela , Bianchi Anna Maria
Published: October 2023

Objective: To explore the changes in the organization of functional brain networks triggered by the execution of a visuo-motor integration task with the dominant and non-dominant hands, as revealed by noninvasive electroencephalographic recordings (EEG) at the sensors level. Methods: EEG data were acquired during the execution of the Nine Hole Peg Test (NHPT) with the dominant and non-dominant hands on a group of 44 right-handed volunteers. Both spectral analysis and phase-based connectivity analysis were conducted in the Theta (ϑ), Mu ( )  and Beta (ß) bands. Moreover, the topological reorganization triggered by motor task execution was explored by means of Graph Theoretical Analysis (GTA). Results: Spectral analysis revealed an increase in the contribute of frontoparietal ϑ rhythm and a diffused reduction of µ and ß oscillations, regardless to the side of the body. Graph GTA showed that dominant hand movement is associated with a pronounced increase in ϑ degree and integration, especially in the Frontoparietal Network (FPN) and Attention Network (AN). The µ band was associated with a reduction of network links and integration. This result was more evident for the right-hand movement in the FPN and Sensorimotor Network (SMN), while similar trends were observed in the AN for the two hands. The ß band showed a movement-related decrease in network degree and integration, regardless of laterality and functional network. Furthermore, correlation analysis highlighted an association between frequency-specific topology measures to task performance for both hands. Conclusions: GTA allows for the identification of the main network organization changes associated with visuomotor integration processes. These changes are frequency-dependent and show different trends for the two sides of the body depending on the functional network. Significance: This study contributes to enhance the understanding of brain network modulations associated with visuo-motor integration tasks and experience-dependent motor abilities during motor execution
Multipath-RTI: Millimeter-Wave Radio Based Device-Free Localization
Authors: Ikegami Togo , Kim Minseok , Miyake Yuto , Tsukada Hibiki
Published: October 2023

This paper presents a novel localization technique—Multipath-radio
tomographic imaging (RTI)—based on millimeterwave (mm-wave) radio
systems, such as 5G mobile and WiGig LAN systems. Because of their high
delay and angle resolutions, mm-wave radio systems can realize highly
accurate device-free localization (DFL) for smart home/smart building
applications. They can thus easily separate the multipath components.
The Multipath-RTI can drastically reduce the number of anchor nodes
using virtual nodes created by multipaths. This paper established the
signal processing procedure for RTI image generation and position
estimation using Multipath-RTI. Then, a practical signal processing
scheme, ray-tracing-assisted Multipath-RTI, is presented, and the DFL
results obtained by multilink double-directional channel sounding
measurements are shown. Here, the position estimation errors in the
measurements were less than 0:5 m for all target positions. Furthermore,
the empirical position estimation errors for a single target under
various conditions obtained by simulations were less than 0:5 m in 96.2
% and 88.0 % of the areas in an L-shaped room and a room with an
obstacle in the center, respectively. The position estimation accuracy
for multiple targets was also evaluated, where, for example, the errors
for three targets were less than 0.1 m at 50 % probability with failure
rates of less than 20 %.
Studying Word Meaning Evolution through Incremental Semantic Shift Detection: A Case Study of Italian Parliamentary Speeches
Authors: Periti Francesco , Picascia Sergio , Montanelli Stefano , Ferrara Alfio , Tahmasebi Nina
Published: October 2023

The study of semantic shifts, that is, of how words change meaning as a consequence of social practices, events and political circumstances, is relevant in Natural Language Processing, Linguistics, and Social Sciences. The increasing availability of large diachronic corpora and advance in computational semantics have accelerated the development of computational approaches to detecting such shifts. In this paper, we introduce a novel approach to tracing the evolution of word meaning over time. Our analysis focuses on gradual changes in word semantics and relies on an incremental approach to semantic shift detection (SSD) called WiDiD. WiDiD leverages scalable and evolutionary clustering of contextualised word embeddings to detect semantic shifts and capture temporal transactions in word meanings. Existing approaches to SSD (a) significantly simplify the semantic shift problem to cover change between two (or a few) time points, and (b) consider the existing corpora as static. We instead treat SSD as an organic process in which word meanings evolve across tens or even hundreds of time periods as the corpus is progressively made available. This results in an extremely demanding task that entails a multitude of intricate decisions. We demonstrate the applicability of this incremental approach on a diachronic corpus of Italian parliamentary speeches spanning eighteen distinct time periods. We also evaluate its performance on seven popular labelled benchmarks for SSD across multiple languages. Empirical results show that our results are at least comparable to state-of-the-art approaches, while outperforming the state-of-the-art for certain languages. 
Lung Grounded-SAM (LuGSAM): A Novel Framework for Integrating Text prompts to Segment Anything Model (SAM) for Segmentation Tasks of ICU Chest X-Rays
Authors: Ramesh Dhanush Babu , Iytha Sridhar Rishika , Upadhyaya Pulakesh , Kamaleswaran Rishikesan
Published: October 2023

Chest radiography is a commonly utilized imaging technique for acquiring Chest X-Ray (CXR) images due to its cost-effectiveness and its role in diagnosing lung?related disorders. Nevertheless, interpreting CXR images can be challenging, and the process of separating the lung field from CXR images can be a valuable tool for assessing and diagnosing lung diseases. While various segmentation methods exist, this study primarily focuses on META’s latest Segment Anything Model (SAM). SAM is an Artificial Intelligence (AI) model designed to segment objects within an image. This research aims to harness SAM’s capabilities for segmenting CXR images. Additionally, we explore the potential of another novel model called Grounding DINO. Grounding DINO is a zero-shot object detection model that utilizes a Swin (Shifted Windows) transformer for extracting image features and BERT (Bidirectional Encoder Representations from Transformers) for extracting textual information. It is primarily employed to detect objects in an image based on a provided text prompt, creating bounding boxes around the objects when certain text and box thresholds are met. These bounding boxes are then used as prompts for SAM to generate segmentation masks. The proposed framework has been assessed on CXRs obtained from patients at Emory Hospital in Atlanta, Georgia, USA and further evaluated using NIH clinical center’s CXR image dataset.

The Role of Dissipated Energy and Stiffness in Enhancing the Fatigue Life of Asphalt Concrete under Environmental Influence
Authors: Sarsam Saad Issa
Published: October 2023

Variation of environmental conditions exhibits various modes of failure of asphalt concrete pavement. Under cold environment, the flexible pavement experience cracking and disintegration, while under hot environment, the pavement practices rutting. Both environmental conditions can enhance the fatigue life of the flexible pavement. In the present work, the role of the change in the dissipated energy, and flexural stiffness of asphalt concrete on its fatigue life under environmental influence have been investigated. Asphalt concrete mixtures were prepared with its optimum asphalt binder requirements, and then compacted into a slab mold by laboratory roller to a target density. Beam specimens were obtained from the prepared slab samples and tested for fatigue life using three levels of constant strain of (750, 400, and 250) microstrain under dynamic flexural stresses. The specimens were tested at (5, 20, and 30) ℃ environment levels. It was noticed that specimens practicing cold environment exhibit shorter fatigue life as compared with those tested at hot environment. However, the flexural stiffness of the beam specimens decline as the testing temperature rises. Such behavior was further supported with the variation in the dissipated energy among testing environment. It was concluded that higher testing environment declines the flexural stiffness, increases the fatigue life, and changes the mode of failure of asphalt concrete from brittle to plastic mode.

Authors: Bingöl Atifet
Published: October 2023

Soil pollution is a significant environmental issue with various causes and consequences. Many industrialized and non-industrialized countries are faced with economic and ecological problems due to toxic element contaminations in soil environments. Especially, soils contaminated with toxic metals pose a major environmental and human health problem that needs an effective and affordable technological solution. Phytoremediation is a process that uses plants to clean up contaminated soil, water, or air. It is an environmentally friendly and cost-effective method for mitigating pollution and is often used in situations where traditional cleanup methods are impractical or too expensive. Vetiver grass is a type of perennial grass native to India. It is widely cultivated for various purposes and has several valuable characteristics such as erosion control and soil improvement. In this study, the tolerance of vetiver grass at phytoremediation of boron polluted soil was examined. For this purpose, to determine the tolerance of the vetiver plant to boron, B from H3BO3 was applied to the soil at concentrations of 0, 10, 20, 40, 60, 80, 100, 200, 300, 400 mg B/kg. The results showed that the increase in boron concentration applied to the soil negatively affected plant growth and significant losses in plant height and weight and no growth was observed in plants above 40 mg/kg boron concentration.

The analytical method should be sensitive, specific, fast and accurate to establish the assurance that the equipments used in manufacturing are free of the unwanted impurity, presence of which may alter the safety and efficacy of the drug product. HPLC, UPLC techniques have established their role in pharmaceutical cleaning validation. Among the modern Analytical tools HPTLC is a powerful analytical method equally suitable for qualitative and quantitative analytical tasks. HPTLC is playing an important role in today analytical world, not in competition to HPLC but as a complementary method. One of the most obvious orthogonal features of the two techniques is the primary use of reversed phases in HPLC versus unmodified silica gel in HPTLC, resulting in partition chromatography and adsorption chromatography respectively. High Performance Thin layer Chromatography (HPTLC) technique is a sophisticated and automated form of the thin-layer chromatography (TLC) with better and advanced separation efficiency and detection limits.

The Normal Tendon and Ligament Anatomy of the Lateral Elbow: Implications for Tennis Elbow Syndrome
Authors: Kirkham Stuart G
Published: October 2023

Introduction: Numerous authors have studied the role that ligaments play in various elbow instability syndromes. There is no published article that has studied the role of ligaments in tennis elbow pathology. Tennis elbow patients exhibit increased pain during elbow extension. Lateral ligaments become taut in extension. Therefore, researchers decided to investigate the possibility of an anatomical link between the tendon and ligament anatomy, and how this might help to understand tennis elbow. Methods: Four fresh cadaveric elbows were dissected. Researchers examined the four tendons which comprise the common extensor origin (CEO). Researchers documented the exact footprint created by each tendon origin creates on the Humerus. Researchers also studied the exact attachments of the various named lateral ligaments both macroscopically and histologically using H and E staining. Results: Four tendons contribute to the CEO: Extensor Carpi Radialis Brevis (ECRB), Extensor Digitorum Communis (EDC), Supinator and Anconeus. All four tendons are inseparably blended together, when viewed under 2.5 x power loupe magnification. The deep fibers of the CEO are inseparably blended with the lateral collateral ligament (LCL). This was confirmed with macroscopic inspection, under 2.5 x loupe magnification, and at histological assessment. Discussion/conclusion-clinical relevance: Researchers already know that the LCL becomes taught in extension, and that the ECRB tendon becomes taut in forearm pronation. These two actions produce two shear forces at the CEO which pull in opposite directions. Researchers have found that these tendons and ligaments are inseparably blended together over a distance of 10 mm-between the lateral epicondyle and the radio capitellar joint line-researchers propose that this unique anatomy creates a specific vulnerable location whereby there exists shear forces between those two layers of collagenous tissue. Researchers propose that this explains the initiation and the perpetuation of tennis elbow lesions. It also explains the clinically observed pain during elbow extension in tennis elbow.

This study explored teachers’ perceptions of English teaching method preferences and learning styles in selected secondary schools of Morogoro Municipality by finding their impacts on teaching and learning styles and the challenges of matching English teaching method preferences and learning styles in secondary schools. The study used an exploratory case study design under a qualitative approach where five teachers from five selected schools consisting of four males and one female were selected purposely and voluntarily to be interviewed using semi-structured questions. The results indicate that three teaching methods are mostly preferred by teachers: learner-centred, engagement style, and multiple styles methods. These methods assist learners to achieve good performance in their studies. Moreover, the aforementioned approaches affect the teaching process as they are more effective in facilitating teachers’ tasks. However, shortage of teaching materials, English language communication barriers, shortage of classroom facilities, and students’ readiness are the challenges in implementing teaching preferences and learning styles in English classes. It is therefore recommended that English teachers should work out to improve their utilization of teaching methods and learning styles to reduce the setbacks found in this study. Additionally, curriculum developers, the Ministry of Education, and other education stakeholders may consider the findings of this study for tackling the challenges faced by English teachers in secondary schools

Statistical learning – the ability to extract distributional regularities from input – is suggested to be key to language acquisition. Yet, evidence for the human capacity for statistical learning comes mainly from studies conducted in carefully controlled settings without auditory distraction. While such conditions permit careful examination of learning, they do not reflect the naturalistic language learning experience, which is replete with auditory distraction – including competing talkers. Here, we examine how statistical language learning proceeds in a virtual cocktail party environment, where the to-be-learned input is presented alongside a competing speech stream with its own distributional regularities. During exposure, participants in the Dual Talker group concurrently heard two novel languages, one produced by a female talker and one by a male talker, with each talker virtually positioned at opposite sides of the listener (left/right) using binaural acoustic manipulations. Selective attention was manipulated by instructing participants to attend to only one of the two talkers. At test, participants were asked to distinguish words from part-words for both the attended and the unattended languages. Results indicated that participants’ accuracy was significantly higher for trials from the attended vs. unattended language. Further, the performance of this Dual Talker group was no different compared to a control group who heard only one language from a single talker (Single Talker group). We thus conclude that statistical learning is modulated by selective attention, being relatively robust against the additional cognitive load provided by competing speech, emphasizing its efficiency in naturalistic language learning situations.

Background. Biological age is a better predictor of morbidity and mortality associated with chronic age-related diseases than chronological age. The estimated difference between biological and chronological age can reveal an individual’s rate of aging.Aim. The aim of this study was to assess the association of cardiovascular risk factors with the rate of aging in people without cardiovascular diseases. Materials and methods. We calculated biological artery age and found associations of “old” arteries and rate of aging with risk factors of cardiovascular diseases in 143 adults without cardiovascular diseases. The data were analyzed by their categorization into 3 tertiles using regression methods.Results. “Old” arteries were associated with chronological age (p < 0,001; ОR = 0,55; 95% CI: 0,43 — 0,71) and hypertension (p = 0,002; ОR = 6,04; 95% CI: 1,98 — 18,42) in general group, age (p < 0,001; ОR = 0,45; 95% CI: 0,30 — 0,68), hypertension (p = 0,004; ОR = 12,79; 95% CI: 2,25 — 72,55) and family history of oncology (p = 0,036; ОR = 0,14; 95% CI: 0,02 — 0,88) in women subgroup and age (p = 0,001; ОR = 0,45; 95% CI: 0,28 — 0,76) and 3rd tertile of glycated hemoglobin (p = 0,041; ОR = 65,05; 95% CI: 1,19 — 3548,29) in men subgroup. Difference between biological and chronological age in a group of “old” arteries was associated with chronological age (p = 0,001; β = -1,24; 95% CI: -1,95 — -0,53) and with chronological age (p < 0,001; β = 1,71; 95% CI: 1,06 — 2,36) and 3rd tertile of glycated hemoglobin (p = 0,009; β = -4,78; 95% CI: -8,32 — -1,24) in group of “young” arteries.Conclusion. This study demonstrates that accelerated arterial aging is associated with hypertension and high levels of glycated haemoglobin.

Currently, an increasing number of patients continue to experience long COVID-19 symptoms after initially contracting the SARS-CoV-2 virus. In this regard, it is important to identify the factors associated with the development of post-COVID syndrome and possible ways to influence them.We examined 100 patients aged 26–80 years. The mean age of all participants was 56 ± 12 years. Patients who had severe coronavirus pneumonia 3 months prior to enrollment experienced mainly fatigue, shortness of breath, sleep disorder, hair loss, joint pain, and headache.In this article, we described the most possible causes and risk factors for the development of post-COVID syndrome.

The aging mechanisms study is one of the most important aims in the field of geroscience and clinical medicine. There has been a wide range of fundamental research data accumulated on this matter. The processes associated with regeneration capability decrease, age-related decline of cell proliferation and resilience are highlighted in vitro studies, as well as on animal models, but their translation into clinical practice has not been carried out yet. Our aim was to study the most important mechanisms of aging and the ways of influencing on them with geroprotective technologies, such as senolytic medications. The relevance of this topic is confirmed by increasing number of launched clinical trials, but their results are often ambiguous and require further analysis and elimination of the identified difficulties and shortcomings. We have searched and analysed the literature over the past 10 years using Pubmed and Scopus, in order to find information about the main mechanisms of aging, and possible use of geroprotective medicatios in clinical practice.

The purpose of the study was to identify trends in investment processes in industrial economic activities, as well as to identify factors influencing them. The decomposition was carried out at the level of the regions of the Russian Federation and the type of economic activity – mining. The hypothesis of the study was that in regions in the structure of gross value added (GVA) of which the share of mining is significant, the investment process is more active. The main research methods were monographic, comparative and correlation analysis, graphic. The analysis made it possible to identify: seven groups of regions by the share of mining in the GVA; increasing the number of regions with a significant share of mining; mainly a strong dependence of the volume of investments on such a feature as the share of DPI in the GVA of the region. From the point of view of economic development in the conditions of sanctions pressure, the need for import substitution and ensuring technological sovereignty, accelerated development of manufacturing industries, as well as other types of economic activity is required. The identified factors affecting the dynamics and volume of investments made it possible to formulate directions for enhancing investment in industry. The directions of future research may be the development of an organizational and economic mechanism at the level of the Russian Federation and individual regions to ensure a significant activation of investments in manufacturing industries and give them an innovative character. The conducted research and its results will be useful to researchers of problems of economic growth and investment development of industry, as well as teachers and students in economic areas.
The Choice of Instruments for Regional Economy Regulation Under Conditions of Political and Economic Turbulence: An Approach from the Position of the Noonomy Concept
Authors:   St. Petersburg State University of Economics, Plotnikov V.A.
Published: October 2023

The modern Russian economy is developing under the influence of a macroeconomic shock caused by external sanctions. The sanctions have caused political and economic turbulence, which leads to an increase in uncertainty and disorientates economic agents regarding the prospects for further development. The impact of turbulence on the economies of regions is not the same, which is necessary to take into account when choosing regulatory instruments. At the same time, in addition to situational anti-crisis measures, this regulation should take into account long-term development trends in order to create incentives for the restructuring of regional economy. The article proposes ways to achieve this considering the provisions of the concept of noonomy.
