Minangkabau Language and Change in People’s Political Orientation
Authors: Asnan Gusti , Oktavianus Oktavianus
Published: July 2023

This article discusses the change in the Minangkabau political orientation from the Dutch colonial era to the present. They pose the Minangkabau language as a political issue in the national interaction. This paper is on how Minangkabau people view their mother tongue as a part of national identity, how they make it as the ammunition for the movement of resentencing to fight against the central government, how Minangkabau people make their mother tongue a part of ethnic identity politics; and how language policy of the Dutch colonial and Republic of Indonesia government influenced the change in Minangkabau political orientation. The analysis proves that language has become inseparable from regional history dynamism and Minangkabau regional-political life. The language attitude of the Minangkabau people in the colonial era showed a high national spirit.
Customary Law and Gender Dynamics of Political Participation in Nigeria
Authors: Olomola Omolade
Published: July 2023

Traditionally, gender and sex are closely linked; however, sex or sexuality differs from gender. Gender has become the preferred form in the 21st century, as it is an important factor to consider when hiring employees and in elections for political positions. Sex and gender constructs are bases for inequality and discrimination against women. Historically, the law as an instrument of social control followed the sex and gender constructs. And since men determined and dominated the law and political institutions, enactments and statutes tolerated and perpetuated women’s subjugation. Enactment, in this sense, refers to the process of passing a law, while a statute is an actual law that has been enacted. Enactment is the procedure by which a statute is created, while a statute is the outcome of that process—a written legal provision that has the force of law. Right from the family home, the female is considered a weaker sex whose voice is not to be heard, talk less about representing the clan in a patriarchal setting. This stereotypic position is prevalent in every facet of life, and it subjects womenfolk to hardship and gender-based discrimination. Although women constitute a large portion of voters, it is difficult for them to be elected to positions. It should be noted that gender is not the sole factor considered during an election. For some voters, a woman’s gender can affect their decision in an election, but generally, people vote for their parties. The dominance of a powerful class of male political elite that has historically run the political system has undermined women’s political participation and reduced their chances of nomination for positions at the party level. This article critically reviews gender issues affecting the stake of women’s political participation and examines the indicators of gender and politics in the traditional African setting within the ambit of women’s rights. Using extant international human rights laws and treaties as a guide, the article resolves that equality in political participation is a right.  It is, therefore, imperative to grant women unfettered access to political participation to achieve Goal 5 of the Sustainable Development Goals, which is gender equality. Gender is woven throughout the SDGs as it sits at the intersection of economic, social, and environmental issues. SDG aim to achieve gender equality and empower all women and girls.
Synthetic DNA-based nanoswimmers driven by enzyme catalysis
Authors: Patiño Tania , Gentile Serena , Baranda Lorena , Del Grosso Erica , Mestre Rafael , Sanchez Samuel , Ricci Francesco
Published: July 2023

We report here DNA-based synthetic nanostructures decorated with enzymes (hereafter referred to as DNA enzyme nanoswimmers) that self-propel by converting the enzymatic substrate into the product in solution. The DNA enzyme nanoswimmers are obtained from tubular DNA structures that self-assemble spontaneously by hybridization of DNA tiles. We have functionalized these DNA structures with two different enzymes, urease and catalase, and show that upon addition of the enzymatic substrate (i.e., urea and H2O2), they exhibit concentration-dependent motion and different motion dynamics, including enhanced diffusion and ballistic motion. These results pave the way for the development of synthetic enzyme-driven nanoswimmers that can self-propel in fluids and have the potential to provide new insights into biological motion dynamics at the micro-nanoscale.

Published: July 2023

COVID-19 represents a novel variant of the coronavirus disease, having rapidly disseminated across the globe. In recent studies pertaining to computer vision, image processing, and classification techniques, numerous methodologies have been introduced employing chest X-ray images and computerized tomography (CT) images. This investigation introduces novel fused deep features founded on CT and X-ray image classification, with the aim of detecting COVID-19 disease. The proposed approach encompasses three key phases: deep feature generation, iterative feature selection, and classification. During the feature generation phase, well-known pre-trained deep convolutional neural networks, namely DenseNet201, MobileNetV2, ResNet18, ResNet50, ResNet101, VGG16, and VGG19, were leveraged. Each network model generated 1000 features, which were subsequently fused, culminating in the acquisition of a final feature vector comprising 7000 dimensions. In order to distill the most pertinent information, the ReliefF and iterative maximum relevance minimum redundancy (RFImRMR) feature selection techniques were employed in the generation of the ultimate feature vector. To evaluate the performance of the proposed method, publicly available datasets of CT images and X-ray images were employed. Notably, the suggested deep learning approach attained accuracy rates of 99.33% and 93.10% for COVID-19 detection using CT and X-ray images, respectively. These achieved results serve as compelling evidence substantiating the efficacy of the proposed fused deep features and RFImRMR-based COVID-19 detection.

Published: July 2023

Purpose: This retrospective study aims to describe the pattern of visual field defects among patients presenting with neuro-ophthalmological diseases in a tertiary hospital of Kathmandu.
Materials and Methods: Medical records of patients undergoing Goldmann visual fields (GVF) for neuro-ophthalmological diseases from July 2019 to June 2021 were retrospectively reviewed. Patient demographics, laterality of the disease, clinical diagnosis and pattern of visual field defect were evaluated and entered and analyzed using SPSS version 20 using descriptive univariate and bivariate analysis.
Results: A total of 216 subjects (378 eyes) with the mean age 34.52±14.80 years were included in the study. The visual field defects were divided 4 categories: optic nerve disorders (76.4%, n=165), chiasmal disorders (17.6%, n=38), retrochiasmal disorders (2.8%, n=6) and miscellaneous (3.2%, n=7). Disc edema/papilledema was the most common diagnosis in optic nerve disorders with enlarged blind spot (79.1%) and constriction of visual fields (18.3%) as pattern of visual field defects followed by optic neuritis. Common lesions affecting the chiasma in our study were craniopharyngioma on whom 50% had the classical temporal field involvement (bitemporal-20%, inferotemporal-20% and superotemporal-10%) and pituitary lesions where 30% showed constriction of peripheral fields, 57.5% showed temporal field defects (mostly superotemporal) in both eyes. Retrochiasmal lesions were less common but all showed a bilateral and homonymous pattern of visual field defect.
Conclusion: Optic nerve disorders were the most common group of conditions undergoing visual fields. Understanding the varied patterns of visual field defects can aid in early diagnosis and guide timely treatment of common neuro-ophthalmological diseases.

Published: July 2023

The cathodic deposition of zinc from simulated chloride wastewater was used to characterize the mass transport properties of a flow-by fixed bed electrochemical reactor composed of vertical stack  of stainless steel nets, operated in batch-recycle mode. The electrochemical reactor employed potential value in such a way that the zinc reduction occurred under mass transport control. This potential was determined by hydrodynamic voltammetry using a borate/chloride solution as supporting electrolyte on stainless steel rotating disc electrode. The results indicate that mass transfer coefficient (Km) increases with increasing of flow rate (Q) where .The electrochemical reactor proved to be efficient in removing zinc and was able to reduce the levels of this metal to lower than 0.7 ppm starting from initial concentration of 48.4 mg dm-3 ppm in 120 minutes using ratio of cathode volume/catholyte volume equal to 0.0075. Sherwood and Reynolds numbers were correlated to characterize the mass transport properties of the reactor as follows:

Naturally occurring radioactive materials (NORM) contaminated sites at Al-Rumaila Iraqi oil fields have been characterized as a part of soil remediation project. Activity of radium isotopes in contaminated soil have been determined using gamma spectrometer High Purity Germanium detector (HPGe) and found to be very high for Al-Markezia, Al-Qurainat degassing stations and storage area at Khadhir Almay region. The activity concentration of samples ranges from 6474.11±563.8 Bq/kg to 1232.5±60.9 Bq/kg with mean value of 3853.3 Bq/kg for 226Ra, 843.59±8.39 Bq/kg to 302.2±9.2 Bq/kg  with mean value of 572.9 Bq/kg for 232Th and 294.31±18.56 Bq/kg to 156.64±18.1 Bq/kg with mean value of 225.5 for 40K. Six hazard indexs radium equivalent, representative level index, adsorbed dose rate in air, annual effective dose equivalent, external hazard index, and internal hazard indexes were calculated to estimate the potential radiological health risk in soil and dose rate associated with it and found to be high. Screening of contaminated soil was performed to evaluate the feasibility of particle size separation. The fractions obtained varied between 75 µm (200 mesh) to 300µm (48 mesh).The results show that the largest weight percent in fine particle size cut ( -75, -125+75, -250+125) µm is 73.9% and all radium isotopes are concentrated in 37.5µm particle size while small fluctuations are observed in the other particle size cuts.
Whether «philosophy after Bucha» is possible: philosophical and theological considerations
Authors: Volkovskyi Volodymyr , Samchuk Roman
Published: July 2023

The article analyses the problem of the current state of philosophy in the context of Russian aggression against Ukraine. It is argued that contemporary philosophers are faced with the question: «How is philosophy possible after Bucha?». It is argued that, on the one hand, this questioning and situation is in many ways similar to similar discourses on «philosophy after Auschwitz» and «philosophy after the Gulag», and on the other hand, it shows a number of ideological and moral flaws in modern society and politics that made this question possible. Another consequence is the failure to learn the lessons of history, which leads to the emergence and growth of new totalitarian leaders who are ready to start wars to achieve their goals, which in the future threaten to escalate to the level of a new World War or the use of nuclear arsenals. Thus, there are grounds to state that not only international organisations such as the UN and the Red Cross are unable to resist authoritarianism and totalitarianism, but also that the worldview and value positions on which their activities are based are ineffective.

Particular attention is paid to the theological aspects of this problem, the peculiarities of its formulation and solution by contemporary theologians. The authors analyse the criticism by Ukrainian intellectuals-philosophers of the prejudices of the Western philosophical establishment, touch upon the doctrine of the «Russian world» as a civil religion with its corresponding dogmas, and finally offer some philosophical conclusions that, in the authors’ opinion, formulate, if not new imperatives, as they somewhat pretentiously call them, then at least new significant accents that Ukraine brings to the world philosophical sphere. Thus, Ukrainian scholars of the social sciences and humanities face a crucial task, not just to reflect or comprehend the reality of life «under the bombs», but to formulate new imperatives that can become the basis for a new post-war philosophy, politics and culture.
Okolo on the Question of African Philosophy and its Periodization
Authors: Ugwu Anayochukwu , Ozoemena Leo Chigozie , Ukwuoma Ikeagwuchi Ikechukwu
Published: July 2023

This paper is an attempt to respond to Okolo’s position that African philosophy emerged at the African-European contact. For Okolo, there was what could be referred to, as expressions of philosophic tendencies which were not philosophy _per se_, called ‘Philosophy in Africa’ which has existed in Africa. They could be explained as basic cultural expressions of the people. But real philosophy characterized by critical reflection began after the Second World War when Africans must have attained some level of formal education and critical reflection, hence ‘African Philosophy’. But then, questions arise: ‘Why, in the first place, questioning African Philosophy but not religion, arts, politics, etc.? Why must African Philosophy, the expression of African-wisdom, be a product of African-European contact? A clear problem in Okolo’s position is the affirmation that everything African, especially the essence of being-African which he designates with the term ‘being-with’ is either non-African-originated, not really a humanistic philosophy or European originated. This paper defends the thesis that ‘being’ implicates the ‘facticity of existence’ which is the central focus of philosophy, and once there ‘is’ in Africa before the African-European contact, there ‘is’ ‘philosophy’ in its real sense. This paper is expected to (1) analyze and expose Okolo’s thought and weaknesses, (2) address the issue of periodization of the African Philosophy hence the position that philosophy has always existed but systems and schools of philosophizing can be found in times, (3) postulate that what is African can commendably sustain Africa. The paper shall adopt philosophical conceptual and contextual analysis and clarifications.

Authors: Neves Nathália Gomes da Silva , Salles Denise Medeiros Ribeiro
Published: July 2023

This article aims to verify the influence of people engagement on the perception of organizational management systems, according to the Job-Demands Resources model in companies in the oil and gas segment that opted to obtain certifications of their management systems through the API (American Petroleum Institute), as well as the benefits of obtaining such engagement and the barriers faced. The research has a qualitative character, and used the triangulation of techniques for obtaining and analyzing data in order to provide an attentive view of the subjective aspects, focusing on the observation of employee involvement, the adoption of good practices and critical success factors in the implementation of the Quality Management System (SGQ)[3]. During the implementation of the SGQ, some challenges were reported with the involvement of employees, need for constant support and feedback, through continuous communication and regarding employees, difficulty in concentrating and prioritizing activities, need for training, more manpower and resistance to change. However, there was a strong positive impact on all the organizations interviewed, contributing to internal improvement, increased customer satisfaction, good reputation, efficient relationship with suppliers, greater control of processes and productivity. It is expected to have contributed to the elaboration, by organizations in the sector, of new people management approaches that strengthen the employee-company relationship, as well as through the exposed questionnaire, a diagnostic mechanism that can be applied in the future by organizations.

Cylindrical Projections as a Limiting Case of Conic Projections
Authors: Lapaine Miljenko
Published: July 2023

Lambert (1772) derived the equation of the Mercator projection as a limiting case of a conformal conic projection. In this paper, we give a derivation for equidistant, equal-area, conformal and perspective cylindrical projections as limiting cases of equidistant, equal-area, conformal and perspective conic projections. In this article the conic and cylindrical projections are not projections on a cone or a cylinder whose surfaces are cut and developed into a plane, but rather mappings of the sphere directly into the plane. Exceptions are projections that are defined as mappings on the surface of a cone or plane, as is the case with perspective projections. In the end, we prove that it is not always possible to obtain a corresponding cylindrical projection as a limiting case from a conic projection, as one might conclude at first glance. Therefore, the final conclusion is that it is not advisable to interpret cylindrical projections as limiting cases of conic projections.
In-situ synchrotron X-ray imaging of ultrasound (US)-generated bubbles: Influence of US frequency on microbubble cavitation for membrane fouling remediation

Published: July 2023

Gaining an in-depth understanding of the characteristics and dynamics of ultrasound (US)-generated bubbles is crucial to effectively remediate membrane fouling. The goal of present study is to conduct in-situ visualization of US-generated microbubbles in water to examine the influence of US frequency on the dynamics of microbubbles. This study utilized synchrotron in-line phase contrast imaging (In-line PCI) available at the biomedical imaging and therapy (BMIT) beamlines at the Canadian Light Source (CLS) to enhance the contrast of liquid/air interfaces at different US frequencies of 20, 28 and 40 KHz at 60 Watts. A high-speed camera was used to capture 2,000 frames per second of the bubble cavitation generated in water under the ultrasound influence. Key parameters at the polychromatic beamlines were optimized to maximize the phase contrast of gas/liquid of the microbubbles with a minimum size of 5.5 mu m. ImageJ software was used to analyze the bubble characteristics and their behavior under the US exposure including the microbubble number, size, and fraction of the total area occupied by the bubbles at each US frequency. Furthermore, the bubble characteristics over the US exposure time and at different distances from the transducer were studied. The qualitative and quantitative data analyses showed that the microbubble number or size did not change over time; however, it was observed that most bubbles were created at the middle of the frames and close to the US field. The number of bubbles created under the US exposure increased with the frequency from 20 kHz to 40 kHz (about 4.6 times). However, larger bubbles were generated at 20 kHz such that the average bubble radius at 20 kHz was about 6.8 times of that at 40 kHz. Microbubble movement/traveling through water was monitored, and it was observed that the bubble velocity increased as the frequency was increased from 20 kHz to 40 kHz. The small bubbles moved faster, and the majority of them traveled upward towards the US transducer location. The growth pattern (a correlation between the mean growth ratio and the exposure time) of bubbles at 20 kHz and 60 W was obtained by tracking the oscillation of 22 representative microbubbles over the 700 ms of imaging. The mean growth ratio model was also obtained.
Self-CATA: a new consumer test approach with descriptors ranked by Stepwise Discriminant Analysis
Authors: Palazzo Alessandra Bugatte , Bolini Helena Maria André
Published: July 2023

The self-CATA test proposed in this study allows consumers an opportunity to supplement the CATA terms with additional vocabulary from a previously generated standard list. Considering that some attributes listed on the CATA test are frequently unselected by consumers because most of them were provided by a previous sensory descriptive panel, even from instrumental or texture parameters, a consensus list to obtain a complete product characterization could be created: a self-own vocabulary list. The work´s design was developed using a CATA-questionnaire containing descriptors provided from a previous panel, ranked by Stepwise Discriminant Analysis to which the consumer’s new repertory was added. In this regard, six raspberry gelatin samples were evaluated by 120-consumers using the self-CATA questionnaire. Results indicated eight new consumer features, not previously verified, such as pink color and odd and metallic flavors. The key-point of this study is to verify a significant choice of CATA terminology.

Authors: Mi Yanlin , Marcu Stefan-Bogdan , Tabirca Sabin , Yallapragada Venkata V. B.
Published: July 2023

Introduction: In the field of bioinformatics and computational biology, protein structure modelling and analysis is a crucial aspect. However, most existing tools require a high degree of technical expertise and lack a user-friendly interface. To address this problem, we developed a protein workstation called PROFASA.

Methods: PROFASA is an innovative protein workstation that combines state-of-the-art protein structure visualisation techniques with cutting-edge tools and algorithms for protein analysis. Our goal is to provide users with a comprehensive platform for all protein sequence and structure analyses. PROFASA is designed with the idea of simplifying complex protein analysis workflows into one-click operations, while providing powerful customisation options to meet the needs of professional users.

Results: PROFASA provides a one-stop solution that enables users to perform protein structure evaluation, parametric analysis and protein visualisation. Users can use I-TASSER or AlphaFold2 to construct protein models with one click, generate new protein sequences, models, and calculate protein parameters. In addition, PROFASA offers features such as real-time collaboration, note sharing, and shared projects, making it an ideal tool for researchers and teaching professionals.

Discussion: PROFASA’s innovation lies in its user-friendly interface and one-stop solution. It not only lowers the barrier to entry for protein computation, analysis and visualisation tools, but also opens up new possibilities for protein research and education. We expect PROFASA to advance the study of protein design and engineering and open up new research areas.

Published: July 2023

This study was based on the concept of teacher professional vision, in which professional reasoning plays a crucial role, and investigated how video with gaze overlay and heatmaps from the mobile eye tracker can support teachers’ professional self-reflection and professional vision development in higher education. Four university teachers wore a mobile eye tracker in a segment of one lecture. Their gaze distribution on classroom targets was analyzed together with their reflective comments when watching the recordings of their own behavior in the lecture. The results showed that mobile eye tracking data provided feedback on the distribution of teacher attention in different areas in the classroom and between students. Visualization of gaze distribution as heatmaps allowed teachers to reflect on how they perceived their gaze allocation and most of them realized that sometimes there was a difference between how they perceived their gaze allocation and how it was captured by the eye tracker. The study revealed where teachers most often diverted their attention, which encouraged them to reflect on why this happened, to think about their professional reasoning, and to analyze opportunities for improvement.

We conducted an annual monthly sampling in the aquaculture areas of Lianjiang and Zhangpu, Fujian province, in the west coast of the Taiwan Strait, to gain insight into the effects of shellfish aquaculture on total phytoplankton biomass and its distribution in phytoplankton size fractions. We observed that the total chlorophyll-a (TChl-a) concentration was higher in Zhangpu (annual mean 2.690 ± 2.375 μg/L) than in Lianjiang (annual mean 1.700 ± 1.500 μg/L) and that Lianjiang had a high N/P ratio during the study, which may have been the main reason for the differences in phytoplankton biomass between the two shellfish aquaculture areas. The response of phytoplankton to shellfish aquaculture was different in the northern versus southern areas. During the aquaculture period of Lianjiang, the TChl-a concentration of surface water was approximately 14% lower than that of bottom water, and such a decreasing trend of Chl-a concentration was consistently present in micro-, nano-, and pico-size fractions. Phytoplankton depletion was not observed during investigation in Zhangpu, which showed highly variable in environmental factors. The contribution of pico-sized Chl-a to TChl-a is evaluated by shellfish aquaculture to some extent in Lianjiang. The shift from the dominance of nano-phytoplankton to the dominance of micro- phytoplankton and pico-phytoplankton was caused mainly by seasonal variation in environmental conditions. In complex marine environments, the distribution of phytoplankton biomass in phytoplankton size fractions showed no significant response to shellfish aquaculture.

Microbial dissimilatory iron reduction is a fundamental respiratory process that began early in evolution and is performed in diverse habitats including aquatic anoxic sediments. In many of these sediments microbial iron reduction is not only observed in its classical upper zone, but also in the methane production zone, where low-reactive iron oxide minerals are present. Previous studies in aquatic sediments have shown the potential role of the archaeal methanogen Methanosarcinales in this reduction process, and their use of methanophenazines was suggested as an advantage in reducing iron over other iron-reducing bacteria. Here we tested the capability of the methanogenic archaeon Methanosarcina barkeri to reduce three naturally abundant iron oxides in the methanogenic zone: the low-reactive iron minerals hematite and magnetite, and the high-reactive amorphous iron oxide. We also examined the potential role of their methanophenazines in promoting the reduction. Pure cultures were grown close to natural conditions existing in the methanogenic zone (under nitrogen atmosphere, N2:CO2, 80:20), in the presence of these iron oxides and different electron shuttles. Iron reduction by M. barkeri was observed in all iron oxide types within 10 days. The reduction during that time was most notable for amorphous iron, then magnetite, and finally hematite. Importantly, the reduction of iron inhibited archaeal methane production. When hematite was added inside cryogenic vials, thereby preventing direct contact with M. barkeri, no iron reduction was observed, and methanogenesis was not inhibited. This suggests a potential role of methanophenazines, which are strongly associated with the membrane, in transferring electrons from the cell to the minerals. Indeed, adding dissolved phenazines as electron shuttles to the media with iron oxides increased iron reduction and inhibited methanogenesis almost completely. When M. barkeri was incubated with hematite and the phenazines together, there was a change in the amounts (but not the type) of specific metabolites, indicating a difference in the ratio of metabolic pathways. Taken together, the results show the potential role of methanogens in reducing naturally abundant iron minerals in methanogenic sediments under natural energy and substrate limitations and shed new insights into the coupling of microbial iron reduction and the important greenhouse gas methane.

Ulcerative colitis (UC) is presently considered a multifactorial pathology, which may lead to persistent inflammatory action of the gastrointestinal tract (GIT) because of an improperly managed immunological reactivity to the intestinal microbiota found in the GIT. The immune response to common commensal microbes plays an essential role in intestinal inflammation related to UC synbiotics, and it is an important element in the optimal therapy of UC. Therefore, synbiotics, i.e., a mixture of prebiotics and probiotics, may help control the diseased state. Synbiotics alleviate the inflammation of the colon by lowering the reactive oxygen species (ROS) and improving the level of antioxidant enzymes such as catalase (CAT), glutathione peroxidase (GPX), and superoxide dismutase (SOD). Prebiotic supplementation is not a common practice at the moment, despite numerous research findings proving that the benefits of both probiotics and prebiotics encourage their continued existence and positioning in the GIT, with positive effects on human health by managing the inflammatory response. However, the fact that there have been fewer studies on the treatment of UC with different probiotics coupled with selected prebiotics, i.e., synbiotics, and the outcomes of these studies have been very favorable. This evidence-based study explores the possible role of ROS, SOD, and synbiotics in managing the UC. The proposed review also focuses on the role of alteration of gut microbiota, antioxidant defense in the gastrointestinal tract, and the management of UC. Thus, the current article emphasizes oxidative stress signaling in the GI tract, oxidative stress-based pathomechanisms in UC patients, and UC therapies inhibiting oxidative stress’ effects.

Objective

To assess the computed tomography (CT) and magnetic resonance (MR) imaging characteristics of soft tissue rhabdoid tumors (RT) and compare them with those of rhabdomyosarcoma (RMS).

Methods

We conducted a retrospective analysis of 49 pediatric patients from 2011 to 2022, comprising 16 patients with soft tissue RT and 33 patients with RMS who underwent CT or MRI scans. Key imaging features, as well as clinical and pathological data, were compared between the two groups. The multivariate logistic regression analysis was used to determine independent differential factors for distinguishing soft tissue RT from RMS, and the model was established. The final prediction model was visualized by nomograms and verified internally by using a bootstrapped resample 1,000 times. The diagnostic accuracy of the combined model was assessed in terms of discrimination, calibration, and clinical utility.

Results

Age, sex, number of lesions, and primary locations were similar in both groups. The imaging characteristics, including margin, calcification, surrounding blood vessels, and rim enhancement, were associated with the two groups of soft tissue tumors, as determined by univariate analysis (all p < 0.05). On multivariate logistic regression analysis, the presence of unclear margin (p-value, adjusted odds ratio [95% confidence interval]: 0.03, 7.96 [1.23, 51.67]) and calcification (0.012, 30.37 [2.09, 440.70]) were independent differential factors for predicting soft tissue RT over RMS. The presence of rim enhancement (0.007, 0.05 [0.01, 0.43]) was an independent differential factor for predicting RMS over soft tissue RT. The comprehensive model established by logistic regression analysis showed an AUC of 0.872 with 81.8% specificity and 81.3% sensitivity. The decision curve analysis (DCA) curve displayed that the model achieved a better net clinical benefit.

Conclusion

Our study revealed that the image features of calcification, indistinct margins, and a lack of rim enhancement on CT and MRI might be reliable to distinguish soft tissue RT from RMS.
Abundant optical solutions for the Sasa-Satsuma equation with M-truncated derivative

Published: July 2023

Here, we look at the Sasa-Satsuma equation with M-truncated derivative (SSE-MTD). The analytical solutions in the form of trigonometric, hyperbolic, elliptic, and rational functions are constructed using the Jacobi elliptic function and generalizing Riccati equation mapping methods. Because the Sasa–Satsuma equation is applied to explain the propagation of femtosecond pulses in optical fibers, the acquired solutions can be employed to explain a wide range of important physical phenomena. Moreover, we apply the MATLAB tool to generate a series of graphs to address the effect of the M-truncated derivative on the exact solution of the SSE-MTD.
