Application of a tripled fixed point theorem to investigate a nonlinear system of fractional order hybrid sequential integro-differential equations
Authors: Jamil Muhammed , Khan Rahmat Ali , Shah Kamal , Abdalla Bahaaeldin , Abdeljawad Thabet
Published: August 2022

The goal of this manuscript is to study the existence theory of solution for a nonlinear boundary value problem of tripled system of fractional order hybrid sequential integro-differential equations. The analysis depends on some results from fractional calculus and fixed point theory. As a result, we generalized Darbo's fixed point theorem to form an updated version of tripled fixed point theorem to investigate the proposed system. Also, Hyres-Ulam and generalized Hyres-Ulam stabilities results are established for the considered system. For the illustration of our main results, we provide an example.
Evaluation of time-fractional Fisher's equations with the help of analytical methods
Authors: Zidan Ahmed M. , Khan Adnan , Shah Rasool , Alaoui Mohammed Kbiri , Weera Wajaree
Published: August 2022

This article shows how to solve the time-fractional Fisher's equation through the use of two well-known analytical methods. The techniques we propose are a modified form of the Adomian decomposition method and homotopy perturbation method with a Yang transform. To show the accuracy of the suggested techniques, illustrative examples are considered. It is confirmed that the solution we get by implementing the suggested techniques has the desired rate of convergence towards the accurate solution. The main benefit of the proposed techniques is the small number of calculations. To show the reliability of the suggested techniques, we present some graphical behaviors of the accurate and analytical results, absolute error graphs and tables that strongly agree with each other. Furthermore, it can be used for solving fractional-order physical problems in various fields of applied sciences.
Fast screening framework for infection control scenario identification
Authors: Kakimoto Yohei , Omae Yuto , Toyotani Jun , Takahashi Hirotaka
Published: August 2022

Due to the emergence of the novel coronavirus disease, many recent studies have investigated prediction methods for infectious disease transmission. This paper proposes a framework to quickly screen infection control scenarios and identify the most effective scheme for reducing the number of infected individuals. Analytical methods, as typified by the SIR model, can conduct trial-and-error verification with low computational costs; however, they must be reformulated to introduce additional constraints, and thus are inappropriate for case studies considering detailed constraint parameters. In contrast, multi-agent system (MAS) simulators introduce detailed parameters but incur high computation costs per simulation, making them unsuitable for extracting effective measures. Therefore, we propose a framework that implements an MAS for constructing a training dataset, and then trains a support vector regression (SVR) model to obtain effective measure results. The proposed framework overcomes the weaknesses of conventional methods to produce effective control measure recommendations. The constructed SVR model was experimentally verified by comparing its performance on datasets with expected and unexpected outputs. Although datasets producing an unexpected output decreased the prediction accuracy, by removing randomness from the training dataset, the accuracy of the proposed method was still high in these cases. High-precision predictions of the MAS-based simulation output were obtained for both test datasets in under one second of the computational time. Furthermore, the experimental results establish that the proposed framework can obtain intuitively correct outputs for unknown inputs, and produces sufficiently high-precision prediction with lower computation costs than an existing method.
The Case of Deutschland 83: Global Internet-Distributed Television and its Effects on Local Viewing Behavior and Industry Practices
Authors: Brüning Kristina
Published: August 2022

This article examines the German drama series Deutschland 83 and its unexpectedly low German viewership as a case study. Highlighting the benefit of integrating audience research into analyses of shifting industrial practices, this article illuminates the complexities of negotiating local tastes in an era of global content flows. Viewer feedback reveals the importance of understanding viewing behavior in the streaming age as a confluence of content-based preferences and expectations of a specific technologically afforded user experience. This shift in viewing behavior not only has implications for production practices and local producers but also informs how local private broadcasters adjust in order to remain competitive within the growing German television landscape.
When a Subculture Goes Pop: Platforms, Mavericks, and Capital in the Production of “Boys’ Love” Web Series in China
Authors: Zou Sheng
Published: August 2022

This article examines the rise, demise, and afterlife of “Boys’ Love” (BL) web series—or male/male romantic dramas—in China. Through the production of culture perspective, it examines how the localization and adaptation of BL in China take shape amid tensions and negotiations between state regulation, digital media production, and commercial interests. Foregrounding the roles of oligopolistic video platforms, private capital, and entrepreneurial writers/directors (whom I conceptualize as cultural mavericks), this article looks at the paradoxical development of BL web series in China, where digital technology and capital catapult the subcultural genre into the limelight while subjecting it to the hegemonic incorporation by mainstream commercial culture. This article contributes to the growing body of work on BL subculture through an underexplored approach that underscores the organizational and industrial structures shaping local BL production. My analysis situates BL production within a transmedia ecosystem and approaches it not only as an emergent cultural phenomenon but also as an organic cultural economy. Through the case of Chinese BL web series, this article opens up broader discussions on the ontological dilemma of subcultures as well as the interplays between marginal and mainstream cultural formations.

A Granular Approach to Secure the Privacy of Electronic Health Records Through Blockchain Technology
Authors: Jain Megha , Pandey Dhiraj , Sharma Kewal Krishna
Published: August 2022

The method of storing data in traditional Electronic Health Records (EHRs) becomes even more obsolete when it has to undertake data from more than one institution. This problem is bigger than it seems as, most of the times the patients' medical data is scattered among various Healthcare Centers. Also, these multiple and inconsistent health records are almost never reviewed which further makes them unreliable. All this can be achieved by implementing the Blockchain Technology into the traditional Electronic Health Records. We propose a blockchain technology based Electronic Health Record portal for patients, doctors, and other users to provide temper proof, secure, and efficient access to health records while maintaining the privacy of patient’s health records. The aim of this paper is to deal with the various needs of patients, doctors, and third parties, as well as to see how the system could resolve privacy and security issues in the healthcare industry.
Watermarking of EEG Data to Provide Security Based on DWT-SVD and Optimized by Firefly Algorithm
Authors: Gupta Akash Kumar , Chakraborty Chinmay , Gupta Bharat
Published: August 2022

A watermark embedding into digital media or signal is called digital watermarking for the purpose of enhancing security from copyright encroachment. In this paper, an optimized and advanced watermarking technique has been proposed, which is based on singular value decomposition (SVD) in the discrete wavelet transform (DWT) domain using the firefly algorithm (FA). In this, a watermark logo is embedded into electroencephalogram (EEG) data. To optimize the scaling factor, robustness and imperceptibility have been considered. Further, the performance of the proposed algorithm is also analyzed against various attacks. The results show the adequacy of the proposed algorithm and indicate a higher value of NCC of 0.95 as robustness and PSNR 51.83 as imperceptibility in contrast with the related existing method.

Democracy, Authoritarianism and the Inflow of Foreign Direct Investments: A Critical Examination of a Debate and its Associated Consequences for Social Science Research
Authors: Salami Adebayo T.
Published: August 2022

Are debates of value to social science research? To what extent has the debate on the preconditions and determinants of foreign direct investments (FDI) helped in the understanding of the totality of the forces, factors, and processes of international capitalism? How does the knowledge of the preconditions and determinants present themselves as the knowledge of the debate on how best to attract and stimulate FDI? To what degree/extent do regimes necessarily influence and shape the determinants and preconditions of FDI attractions and stimulations? How can the research on the preconditions and determinants of FDI be designed in such a way and manner that the purpose of the scholarship is best served? What are the associated consequences of the choice and technique of the research design? The article attempts a review of the significant initiatives that give meaning to the debate on the affinities of FDI to either democracy or authoritarianism and presents the debate within the intellectual foundation stones of the understanding and grasp of international political economy. The method of data collection is qualitative and scattered in the diverse sources of information on the subject of study. The objective is to contribute meaningfully to understanding the debate and chart future research directions. The study finds out that while the debate on the subject matter is scintillating, it is, however, convoluted by three interrelated failures and shortcomings: (i) lack of clear specification of the research period, (ii) lack of detailed examination of the domestic economy of study, and (iii) lack of comparative study of the periods, which altogether compound the likelihood of in-depth knowledge and generalization, the ultimate goal of academic debates.
Effectiveness of Mobile Assisted Vocabulary Learning Applications (MAVL) as a self-learning tool for ESL learners in Sri Lanka
Authors: Fernando W. W. A. P. H.
Published: August 2022

The advancements in mobile technologies have changed how teaching and learning processes are conducted in the higher education sector. Mobile-Assisted Vocabulary Learning (MAVL) is a part of Mobile Assisted Language Learning (MALL) which is now a demarcating element in the ESL (English as a Second Language) classroom for the language improvement of the learners. MAVL applications are used widely in international language education, yet in Sri Lanka, language learners are limited to printed materials which are not enough to maximize their updated vocabulary knowledge. MAVL applications are used among Sri Lankan ESL learners hardly less than printed material to learn vocabulary and enhance it, which creates the research gap in this study. The research aims to introduce professional and practical MAVL applications to enhance vocabulary, introduce MAVL applications as a helping tool, and enhance their vocabulary and writing competence. The research has experimented with a mixed-method approach, with a sample of twenty ESL learners and five ESL teachers from the university sector. The questionnaire, interviews, and two tests were conducted for the data collection. The results revealed that students found the MAVL application practical, motivating, and helpful. Further, the participants had the potential to use the applications independently, and it made teachers conduct lessons efficiently in the classrooms. The results illustrated that MAVL applications contained positive attitudes toward making mobile-assisted vocabulary improvements. It can be concluded that using MAVL Applications as a self-learning tool would improve ESL learners' vocabulary and the teaching-learning process.

Authors: Kodithuwakku Sujeewa , Priyanath H. M. S.
Published: August 2022

The study seeks to investigate the impact of intellectual human capital and knowledge acquisition capabilities on the firm’s financial performance, particularly in indigenous craft industries in Sri Lanka. The quantitative data were collected from 355 owners of indigenous craft industries located in traditional handicrafts villages in Sri Lanka and analyzed with the help of a Partial Least Squire Structural Equation Model (PLS-SEM). The empirical results show that intellectual human capital has a significant positive impact on the financial performance of indigenous craft industries. Further, it was found that knowledge acquisition capabilities have a significant positive impact on the firm’s financial performance. In addition, the study identified that knowledge acquisition capabilities have a significant positive mediating effect on the relationship between intellectual human capital and the firm’s financial performance. Thus, the study found that the intellectual human capital of owners is the most powerful intangible resource, which has a significant positive impact on a firm’s financial performance. The study suggests to owners of the indigenous craft industries, policymakers, donors, and others to incorporate the strategies to develop and strengthen the efficiency and productivity of intellectual human capital to improve their financial performance.
Decolonising and indigenising evaluation practice in Africa: Roadmap for mainstreaming the Made in Africa Evaluation approach
Authors: Dlakavu Ayabulela , Mathebula Jabulani , Mkhize Samukelisiwe
Published: August 2022

Background: Decolonisation is a concept that has taken on multiple layers since the end of colonisation and the onset of independence in the Global South. More than ever before, decolonialism, decoloniality and indigenisation have moved to the centre of intellectual inquiry across the broad spectrum of human activity: knowledge production, education, academic disciplines, professions, political life and economic organisation. The evaluation profession and fraternity has also been grappling with the idea of decolonising and indigenising its ontological, epistemological and methodological foundations, which are essentially rooted in the Global North development theory, practice and knowledge systems.Objectives: This article endeavours to provide recommendations on how to make the Made in Africa Evaluation (MAE) paradigm practical (applicable) for evaluators in Africa, based on decolonisation and indigenisation methodological prescriptions.Method: The study is qualitative by design, employing document analysis and the authors’ observation on development and evaluation practice in Africa and globally.Results: The emergent practice of evaluation is only experiencing decolonial scrutiny in the 21st century. In the African context, the MAE paradigm appears to be the continent’s decolonisation and indigenisation project for the evaluation fraternity.Conclusion: Building an Afrocentric, decolonised and indigenous MAE paradigm and approach requires a coordinated effort on building scholarship on the topic of MAE approaches and methodologies. Once there is sufficient documentation of the MAE approach, it should become easier to advance Afrocentric evaluation as mainstream discourse alongside the more established and neoliberal development and evaluation discourse.
Theology in dialogue and dialogue in theology: Destroying the walls of hostility
Authors: Resane Kelebogile T.
Published: August 2022

Dialogue has the power to calm the conflicts, misunderstandings and prejudices among people of different cultures, religions, theologies and worldviews. This article points out that theology and dialogue are inseparable. It endeavours to find a definition of dialogue and its role in theology and how theology expresses itself through dialogue. The church speaks through dialogue, and theology’s voice is heard mostly from and through the church. It is a dialogue that spearheads the shape and formation of theology. All the biblical dialogues are theological in content. The role played by the biblical text during the dialogical processes is very important. A theologian affirms and embraces the text through communicating with it. He or she must always attempt to engage the movements and the thoughts of the text. Texts are primarily powerful instruments of groups and only second-line power tools of individuals. The principles of comparative theology are ideal in any dialogue. Dialogues are the meeting points of theology and dialogist as the confessors express themselves to God through dialogue. The dialogical spaces become sacred spaces because it is where dialogue partners encounter a common commitment to justice. Dialogues are not necessarily theological because non-Christian religions and natural sciences are encountered in and through dialogues.Intradisciplinary and/or interdisciplinary implications: This article acknowledges the realities of civil strife in the communities and that this strife creates walls between the people. A solution to this tension is that theology through dialogue should engage all sciences, natural or social, for harmonious co-existence within humanity.

Published: August 2022

Coronavirus disease 2019 (COVID-19) has many cutaneous manifestations. We describe a 30-year-old otherwise healthy male with a generalized purpuric exanthem. Ten days after the onset of the rash, he presented with fatigue, dry cough, shortness of breath, anosmia, and ageusia and was diagnosed as having COVID-19. The presence of an extensive exanthem in an otherwise healthy patient could raise suspicion for underlying COVID-19.

People affected with severe acute respiratory syndrome coronavirus 2 can have a wide variety of symptoms. Literature and public discussion forums report persistent symptoms among COVID-19 survivors. More than 25% of COVID-19 survivors report hair loss as a persisting issue. The Centers for Disease Control and Prevention state that hair loss as a potential long-term effect of COVID-19 is currently under investigation. This report may be the first case of hair loss in the patient with postCOVID-19 infection in Saudi Arabia.
A Case of Topical Rapamycin Effective for Postsurgical Hypertrophic Scar of Superficial Lymphatic Malformation with Possible Quality-of-Life Improvement
Authors: Isozaki Yuki , Kato Motoi , Fujita Naoko , Tojo Shota , Fujiki Masahide , Watanabe Azusa , Watanabe Shoji
Published: August 2022

Lymphatic malformation (LM) of the body surface causes symptoms such as bleeding, pain, lymphatic leakage, or infection of the lesion, usually treated with surgical resection and sclerotherapy, with limited efficacy. The vesicles of the body surface tend to recur after surgical resection and may cause lymphatic leakage, which could be long term a burden for patients, eventually decreasing their quality of life. In recent years, the efficacy of orally administered mammalian target of rapamycin inhibitor (rapamycin) has been reported for LM and other vascular anomalies but few are reported in the East Asian population. We report the case of a Japanese female with intractable gluteal LM that was successfully treated with topical rapamycin for postoperative recurrence and hypertrophic scarring.
Interesting Arrhythmogenic Right Ventricular Cardiomyopathy
Authors: Adhyapak Srilakshmi M. , Gupta Anuraag , Shaikh Jabraan U. , Kramadhari Harshith , Varghese Kiron
Published: August 2022

A normotensive, euglycemic 24-year-old male presented with presyncope. There was no history of similar episodes or loss of consciousness. No similar family history was noted. General clinical and cardiovascular examination was unremarkable. Electrocardiogram done showed wide complex tachycardia with a left bundle branch block morphology suggestive of ventricular tachycardia. The tachycardia spontaneously reverted to normal sinus rhythm. The patient subsequently had sinus bradycardia with a heart rate of 58/min and demonstrated an epsilon wave in the inferior and right-sided chest leads. His cardiac magnetic resonance imaging showed a dilated right atrium and ventricle with no fibrofatty infiltration. This patient did not fulfil the criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) according to the 2020 criteria. He qualified for suspected ARVC. However, according to the Heart Rhythm Society guidelines of 2019, he qualified as ARVC as he met two major criteria. We report this case as we feel that the criteria for diagnosis of ARVC may not warrant strict adherence. A strong clinical suspicion is required in addition for diagnosis.
A Rare Case of Giant Unruptured Sinus of Valsalva Aneurysm
Authors: Mishra Biswaranjan , Pattnaik Harsha
Published: August 2022

Sinus of Valsalva aneurysm is a rare congenital disorder that usually presents with rupture of the aneurysm into adjacent cardiac structures. It usually arises from the right sinus of Valsalva which ruptures into the right ventricle or right atrium (RA). Aneurysms may also arise from the noncoronary cusp that rupture into RA. Rarely, an unruptured aneurysm may compress or dissect into the adjacent structures and produce obstruction to either left or right ventricular outflow or produce conduction blocks. It may also intrude upon valves affecting valvular function. Here is a case of an unruptured giant aneurysm arising from the right sinus of Valsalva burrowing into the interventricular septum (IVS) causing conduction defect in the form of left bundle branch block with first degree atrioventricular block. Through IVS, it protruded into the left ventricular (LV) outflow tract (LVOT) giving rise to a cystic appearance causing mild LVOT obstruction and mild-to-moderate aortic regurgitation. The aneurysm also affected mitral valve function causing severe mitral regurgitation (MR) including characteristic diastolic MR due to prolonged PR interval. There was no regional wall motion abnormality indicating the absence of coronary arterial obstruction by the aneurysm. Left atrial and LV dilatation was present along with LV systolic dysfunction. Pulmonary arterial systolic pressure was approximately 48 mmHg as calculated from tricuspid regurgitation (TR) gradient. Like MR, TR also showed diastolic TR.
Pilot Study Analyzing Combination of Point-of-Care Echocardiography and Clinical Correlation in Unveiling Cryptic Multi-Inflammatory Syndrome in Neonates during Coronavirus Disease 2019 Pandemic
Authors: Chaudhuri Maitri , Tomar Munesh , Gaonkar Seema , Rastogi Anuj , Shenoi Arvind
Published: August 2022

Introduction:

Coronavirus disease 2019 (COVID-19), an extremely contagious pandemic, caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), originated from Wuhan, Hubei province, in China in December 2019. From April 2020, pediatric epicenters in Europe and the USA reported a new clinical spectrum called “pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2” or “multisystem inflammatory syndrome in children,” respectively. The unique feature was immune-mediated multiorgan dysfunction in response to previous COVID exposure. This case series aims to prospectively analyze the incidence, severity, and patterns of cardiac involvement in sick neonates exposed to perinatal SARS-CoV-2 in India.

Methods:

Twelve neonates presenting with very early-onset multi-inflammatory syndrome in neonates (MIS-N) at two tertiary care centers in India were included. Their clinical profiles, echocardiography findings, and treatment details were recorded.

Results:

Clinical presentations varied from loss of fetal movement, perinatal depression, prematurity, unusual respiratory distress syndrome, cardiogenic shock, arrhythmias, and multi-organ dysfunction. Echocardiographic markers were severe pulmonary hypertension, significant valvular regurgitation, cardiomegaly, biventricular dysfunction, neonatal coronary artery aneurysms, intracardiac thrombus, pericardial effusion, and arrhythmias. All babies, except one, had positive COVID IgG antibody and high inflammatory markers. Two mothers had antenatal primary contact with COVID patients 4–6 weeks prior to delivery, while 3 (25%) had documented mild COVID infection. All neonates were started on immunosuppressive therapy. Clinical stabilization and declining inflammatory markers were observed within 48–96 h of targeted therapy. All neonates (except one) recovered and were discharged in a stable condition. Follow-up available up to 9 months demonstrated persistent clinical, laboratory, and echocardiographic recovery in all survivors.

Conclusion:

Infection of pregnant mothers during community transmission during the two COVID-19 waves in India appears to have caused significant immune dysregulation and cardiac damage in neonates. Echocardiography detected significant damage to coronary arteries, pulmonary arterial hypertension, intracardiac thrombus, ventricular dysfunction, and incompetence of valve apparatus in MIS-N. Aggressive immunomodulators with antiplatelet drugs proved lifesaving. Echocardiography is an inexpensive, readily available imaging modality. It should be utilized to save this fragile, extremely special cohort.
Treatment and Control of Diabetes in India
Authors: Daniel Roy Arokiam , Mani Kalaivani , Aggarwal Praveen , Gupta Sanjeev Kumar
Published: August 2022

Background:

Diabetes is a major contributor to hospital admissions, out-of-pocket expenditure, and premature mortality in India. Proper treatment and adequate control rates are needed to reduce the complications and deaths due to diabetes. Hence, we conducted a systematic review and meta-analysis of community-based studies to estimate the treatment and control rate of diabetes among adults in India.

Methods:

A systematic electronic search was conducted in PubMed, Embase, Cochrane Library, and Google Scholar to retrieve community-based studies which reported the prevalence of treatment and control of diabetes among adults in India, without any date or language restriction. To estimate the pooled prevalence and heterogeneity, the random-effects model and I2 statistic methods were employed. We did subgroup analyses based on study setting and type of blood test.

Results:

We included seven studies in this meta-analysis, which comprised a total of 9,033 participants. The pooled prevalence of treatment and control of diabetes among adults in India was 75.9% (95% confidence interval [CI]: 63.8%–86.2%) and 56.4% (95% CI: 44.7%–67.9%), respectively. There was significant heterogeneity between the studies (P < 0.001). The subgroup analysis based on the study setting revealed a decrease in heterogeneity among the urban studies for the control of diabetes.

Conclusions:

Three-fourths of the diagnosed (self-reported) diabetic patients were on treatment. Of these, half of the patients had adequate glycemic control. Targeted actions need to focus on the determinants of adherence to medication and follow-up.

Authors: Ugalahi Mary O. , Ibukun Folahan A. , Olusanya Bolutife A. , Baiyeroju Aderonke M.
Published: August 2022

Purpose:

To describe the pattern of intraocular pressure (IOP) changes after squint surgery in eyes of black Africans at the University College Hospital, Ibadan, Nigeria.

Materials and Methods:

This was a retrospective review of the clinical records of patients who underwent squint surgery between 2010 and 2019. Data on demographic characteristics, preoperative and postoperative intraocular pressure values, co-existing ocular pathology, type of strabismus, surgery performed, frequency and duration of postoperative topical steroid use and treatment received for elevated intraocular pressure were collected and descriptively summarised.

Results:

Thirty-six (39.1%) out of 92 patients who had squint surgery during the study period met study inclusion criteria. Mean age was 20.5 ± 13.6 years. All patients were administered Maxitrol® ointment postoperatively. Baseline, peak and net change in IOP were 12.9 ± 2.6 mmHg, 21.3 ± 6.8 mmHg and 8.39 ± 7.2 mmHg respectively. Thirty-one (86.1%) patients had elevation in IOP from baseline; 21 (67.7%) of these had significant IOP elevation. Topical steroid therapy was tailed off rapidly for all patients with significant IOP elevation. Twelve patients were commenced on topical IOP lowering medications, with normalization of intraocular pressure in majority of them by three months after surgery.

Conclusion:

Elevated intraocular pressure with the use of topical dexamethasone ointment after squint surgery was common in this study and majority of the patients had significant elevation in intraocular pressure. Close monitoring of the intraocular pressure of black patients, especially children, on topical steroid medication after squint surgery is strongly recommended.

Published: August 2022

Purpose:

The aim of this study was to determine the spectrum of eye disorders in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).

Materials and Methods:

A cross-sectional hospital-based study was conducted among 100 consecutive patients with RA and SLE. A semi-structured questionnaire was used to obtain details of patients’ sociodemographics, type of rheumatic disease, and prescribed medications. Each patient had a detailed examination of the anterior and posterior segments of the eye. Refraction, intraocular pressure measurement, Schirmer’s test, tear breakup time, gonioscopy, and dilated fundoscopy were also done. Fundus photograph, central visual field assessment, and optical coherence tomography were done as necessary. Analysis was done with the Statistical Package for Social Sciences (SPSS) version 25. Statistical significance was set atP< 0.05.

Results:

A total of 100 patients consisting of 74 RA and 26 SLE patients were evaluated. The female: male ratio was 4.3: 1 for RA, and all SLE patients were females. The prevalence of eye disorders was 42% in all patients; it was 41.9% and 42.3% among RA and SLE patients, respectively. The most common eye disorders were dry eye (38), refractive errors (18), and cataract (16). The mean age of RA patients with eye disorders (52.19 ± 16.17 years) was significantly higher than those without eye disorders (42.30 ± 13.14 years) (P= 0.005).

Conclusion:

Eye disorders are common in RA and SLE. Comprehensive eye examination should be done on all RA and SLE patients at diagnosis and before commencement of medications, and patients should be referred promptly for evaluation when they have eye complaints.

Published: August 2022

Purpose:

The aim of this article is to evaluate the accuracy of placental thickness (PT) in determination of gestational age (GA) in normal singleton foetuses.

Materials and Methods:

The study was a cross-sectional descriptive study which recruited consecutively a total of 406 pregnant women with singleton pregnancies (at 15–40 weeks of gestation), referred for routine obstetric ultrasound (US) scan at the National Hospital, Abuja from October to December 2019. Biparietal diameter (BPD), femur length (FL), head circumference (HC), abdominal circumference (AC), and PT were measured using standard protocols. All measurements were calculated by taking three best measurements, and the mean of the measurements was taken and recorded for each participant. Pearson’s correlation analysis was computed to determine linear relationships between variables. A significant statistical level was determined at a critical value of P < 0.05.

Results:

The mean age was 31.8 ± 4.8 years. The mean PTs in the second and third trimesters were 23.2 ± 3.1 and 34.1 ± 3.7 mm, respectively. PT had a linear relationship and a statistically significant positive correlation (r=0.99, P = 0.00) with GA. There was also a statistically significant positive correlation between PT on the one hand, and BPD, AC, HC, FL, PT, and GA, on the other hand.

Conclusion:

There was a significant and strong positive correlation between PT and GA. The study shows that US measurement of PT is a reliable method of estimating GA in singleton pregnancies in Nigeria.

Published: August 2022

Spinal arteriovenous malformations are rare vascular anomalies within the paediatric age group. These anomalies are associated with devastating consequences and require prompt management to prevent the long-term neurological sequelae. We report a case of a 10-year-old boy with tetraparesis secondary to spinal arterio- venous malformation type III (Juvenile AVM) with rapidly deteriorating neurological signs who had to be managed conservatively due to lack of advanced neurosurgical facilities and interventional radiological services in our facility and sub region.
Timing of urinary catheter removal after radical hysterectomy for cancer of the cervix and uterus
Authors: Billod Jimmy A.
Published: August 2022

BACKGROUNDAND OBJECTIVE:

Radical hysterectomy remains to be the first surgery for early-stage cervical and selected stage 2 endometrial carcinoma. Functional disorders of the lower urinary tract are the foremost common complications following radical surgery necessitating catheterization. This study was undertaken to determine the number of postoperative days (POD) of the removal of urinary catheters after hysterectomy and assess the practicability of earlier removal of the catheter without compromising the bladder function.

METHODOLOGY:

A descriptive observational study of patients who underwent Type 2 or 3 hysterectomy for cervical or endometrial carcinoma. Clinical, intraoperative, and anesthesia records and results of the histopathologic reports of every patient were reviewed. Demographic, clinical, and histopathologic data needed during this review were recorded. Descriptive statistics were used.

RESULTS:

Between January 2016 and December 2019, a complete 45 patients underwent radical hysterectomy (43 patients for cervical cancer and a pair for endometrial carcinoma), with a median age of 50 years. The mean operative time is 2.5 h and also the average blood loss is 500 ml. The mean size of the cervical tumor was 2.2 cm, the mean length of the vagina was 2.5 cm, and the mean lateral width of parametria was 3.6 cm. Catheters were removed between the 3rd and 20th (mean = 6 days) POD. All patients had adequate spontaneous void within 6 h after removal. Five patients had their catheters removed beyond 7 days, 3 patients between POD 8 and POD 14, and 2 patients between days POD 15 and POD 20. All patients were able to return to bladder function within 3 weeks of catheterization.

CONCLUSION:

The outcome showed that earlier removal of catheter seems to be a practical and safe option compared to long-term catheterization for patients who underwent radical hysterectomy without causing morbidities.
Lorentzian fermionic action by twisting Euclidean spectral triples
Authors: Martinetti Pierre , Singh Devashish

We show how the twisting of spectral triples induces a transition from a Euclidean to a Lorentzian noncommutative geometry at the level of the fermionic action. More specifically, we compute the fermionic action for the twisting of a closed Euclidean manifold, then that of a two-sheet Euclidean manifold, and finally the twisting of the spectral triple of electrodynamics in Euclidean signature. We obtain the Weyl and the Dirac equations in Lorentzian signature (and in the temporal gauge). The twisted fermionic action is then shown to be invariant under an action of the Lorentz group. This permits us to interpret the field of 1-form that parametrises the twisted fluctuation of a manifold as the (dual) of the energy-momentum 4-vector.
Accurate comparison of tree sets using HMM-based descriptor vectors
Authors: Iloga Sylvain
Published: August 2022

Trees are among the most studied data structures and several techniques have consequently been developed for comparing two trees belonging to the same category. Until the end of year 2020, there was a serious lack of suitable metrics for comparing two weighted trees or two trees from different categories. The problem of comparing two tree sets was not also specifically addressed. These limitations have been overcome in a paper published in 2021 where a customizable metric based on hidden Markov models has been proposed for comparing two tree sets, each containing a mixture of trees belonging to various categories. Unfortunately, that metric does not allow the use of non metric-dependent classifiers which take descriptor vectors as inputs. This paper addresses this drawback by deriving a descriptor vector for each tree set using meta-information related to its corresponding models. The comparison between two tree sets is then realized by comparing their associated descriptor vectors. Classification experiments carried out on the databases FirstLast-L (FL), FirstLast-LW (FLW) and Stanford Sentiment Treebank (SSTB) respectively showed best accuracies of 99.75%, 99.75% and 87.22%. These performances are respectively 40.75% and 20.52% better than the tree Edit distance respectively for FLW and SSTB. Additional clustering experiments exhibited 54.25%, 98.75% and 75.53% of correctly clustered instances for FL, FLW and SSTB. No clustering was performed in existing work.
Further results on Hendry's Conjecture

Recently, a conjecture due to Hendry was disproved which stated that every
Hamiltonian chordal graph is cycle extendible. Here we further explore the
conjecture, showing that it fails to hold even when a number of extra
conditions are imposed. In particular, we show that Hendry's Conjecture fails
for strongly chordal graphs, graphs with high connectivity, and if we relax the
definition of "cycle extendible" considerably. We also consider the original
conjecture from a subtree intersection model point of view, showing that a
result of Abuieda et al is nearly best possible.
El mal, la macroeconomía y el nacionalsocialismo
Authors: Peralta García Yankel
Published: August 2022

El presente artículo aborda la cuestión ética del nazismo desde el punto de vista de las relaciones sociales de producción. Esto supone vincular la puesta en marcha de la ideología fascista con sus condiciones económicas. En este sentido, la principal propuesta del trabajo consiste en resaltar el hecho de que crímenes como los cometidos por el régimen nazi no solo son posibles con base en una monstruosa formación burocrática, sino también a partir de una dinámica de producción e intercambio sumamente permisiva. No obstante, la autonomía que sobre el factor ideológico del fenómeno se pueda reclamar enfrenta límites muy estrictos. En el caso del “nacionalsocialismo”, tales límites quedaron de manifiesto en el abatimiento de la demanda, el incremento de la deuda y la inhibición del uso productivo del capital. Es como si el Mal se hubiera encarnado a costa de mermar sus condiciones de posibilidad.
Digital Transmission in Computer Network
Authors: Sahota Komal
Published: August 2022

A type of signal transmission known as "digital transmission" involves the discrete time variation of two values, one of which represents the binary number "0" and the other "1." Voltage or electrical potential is often the variable amount in copper cabling. Fiber-optic wiring or wireless communication use variations in intensity or any other physical quantity. Digital signals use discrete values to transmit binary data through a communication path like a network cable or a telecommunications link. On a serial transmission line, a digital signal is transmitted one bit at a time. Analog and digital methods can both be used to store data or information.

AI (Artificial Intelligence) is intelligence shown by machines, rather than the natural intelligence
showed by creatures including people. AI allows machines to learn from experiences and situations,
adapt to new information sources and perform human-like errands.
Now a days we have to make sure what we see is real or fake because development in AI and deep
neural networks have prompted a rise in synthetic media, i.e., artificially generated or controlled
photograph, video and audio content. Synthetic media today is exceptionally believable to such an
extent that we can never again believe what we see or hear is pure and real.Among the various types
of synthetic contents, the most concerning types are deepfakes and general adversarial networks
(GANs).
This new reality can have critical ramifications for network protection, duplicating, counterfeit news,
and border security,fake alligations etc.
Doxology of God in Prayers by the Lake of Bishop Nicholai Velimirovich
Authors: Končarević Ksenija
Published: August 2022

Abstract: In this paper, the author investigates the question of the units by which God is named in Bishop Nicholai Velimirovich’s Prayers by the Lake. The choice of the units by which God is named in the Prayers by the Lake is usually determined by the subject of the prayer itself. Bishop Nicholai expresses his creativity by using names for God of biblical origin. And even more, he enriches already established, common expressions with God as denotation with new meaning dimensions, which is also an expression of his authentic creativity. With such a procedure, he realizes the fullness of meaning and highlights the expediency, stylistic functionality, and beauty of the chosen expression.
In Prayers by the Lake, metaphorical representations form a semantic-symbolic base from which a rich series of metaphorical and comparative nominative constructions will be born, with which Bishop Nicholai addresses God in prayerful ecstasy.
The analysis of the nominative units with God as the denotation used in the Prayers by the Lake only somewhat illustrated the poetic prayer soarings of Bishop Nicholai Velimirovich, which reach the psalmistic ecstasy. Although prayers are characterized by a high degree of formality in the form of the existence of established linguistic structures, Bishop Nicholai Velimirovich’s Prayers by the Lake are to a significant extent a reflection of the individual style of high literary-artistic and authentic theological value.
Key words: Bishop Nicholai Velimirovich, Prayers by the Lake, theolinguistics, prayer.
