Abstract
Millisecond pulsars are subject to accelerations in globular clusters (GCs) that manifest themselves in both the first and second spin period time derivatives, and can be used to explore the mass distribution of the potentials they inhabit. Here we report on over 20 yr of pulsar timing observations of five millisecond radio pulsars in the core of the core-collapse GC NGC 6752 with the Parkes (Murriyang) and MeerKAT radio telescopes, which have allowed us to measure the proper motions, positions, and first and second time derivatives of the pulsars. The pulsar timing parameters indicate that all the pulsars in the core experience accelerations and jerks that can be explained only if an amount of nonluminous mass of at least 2.56 × 103
M
⊙ is present in the core of NGC 6752. On the other hand, our studies highly disfavor the presence of an intermediate-mass black hole at the center of the cluster, with a mass equal to or greater than ∼3000M
⊙.

Abstract
We present the identification and physical analysis of a possible magnetic island feature seen in white-light images observed by the Wide-field Imager for Solar Probe (WISPR) on board the Parker Solar Probe. The island is imaged by WISPR during Parker's second solar encounter on 2019 April 6, when Parker was ∼38 R
⊙ from the Sun's center. We report that the average velocity and acceleration of the feature are approximately 334 km s−1 and −0.64 m s−2. The kinematics of the island feature, coupled with its direction of propagation, indicate that the island is likely entrained in the slow solar wind. The island is elliptical in shape with a density deficit in its center, suggesting the presence of a magnetic guide field. We argue that this feature is consistent with the formation of this island via reconnection in the current sheet of the streamer. The feature's aspect ratio (calculated as the ratio of its minor to major axis) evolves from an elliptical to a more circular shape that approximately doubles during its propagation through WISPR’s field of view. The island is not distinct in other white-light observations from the Solar and Heliospheric Observatory and the Solar Terrestrial Relations Observatory coronagraphs, suggesting that this is a comparatively faint heliospheric feature and that viewing perspective and WISPR’s enhanced sensitivity are key to observing the magnetic island.

Digitization, powered by the Internet, artificial intelligence, inter-operabile data formats and communication standards, high-bandwidth mobile technology, and nano-technology, allows for an increasing number of new services that are tailored to the particular demands of end-users, industry and government organizations.
However, these new digital services have also become the major focus of cyber-crime. Whereas traditional research mostly covered pure technical aspects of cybercrime, it is becoming increasingly important to address cybercrime and cybersecurity in a multidisciplinary fashion, including legal, behavioral, technical and sociological aspects.
This special issue aims to offer a mixture of selected extended versions of papers presented at the European Interdisciplinary Cybersecurity Conference (EICC&rsquo;23), which took place in Stavanger, Norway, as well as submissions from an open call. We con-sidered papers dealing with the above-mentioned risks and problems, new challenges, interdisciplinary issues, and innovative multidisciplinary solutions (defense mechanisms, methods, and countermeasures) for promoting cybersecurity in the cyberspace.
Overall, we received 15 submissions. Each accepted paper received at least three reviews. After a first round of reviews, eight where rejected. The remaining seven papers underwent another round of reviews (five papers underwent a major revision and only two papers were scheduled to undergo a minor revision). Finally, the authors of these seven papers adequately addressed the reviewers&rsquo; comments and they thus have been accepted for inclusion in this special issue.&nbsp;
We like to thank all authors who submitted their work to this special issue and all reviewers for their contributions. Further, we like to thank the J.UCS team for accepting our special issue for inclusion in their journal. We hope that all readers will enjoy this special issue.
To advocate or assimilate: Lessons of queer educators navigating their high school space
Authors: Maseko Siphesihle N. 
Published: September 2024

Background: In South African high schools, queer educators face a unique set of challenges as they navigate the delicate balance between advocating for queer identities and assimilating into institutional norms.Objectives: This article delves into the experiences of three queer educators, examining the complex dynamics of performing their professional roles as educators, advocating for queer identities while navigating institutional, cultural, and personal constraints. This article endeavours to address this gap by delving into the lived experiences of queer educators navigating their roles within the high school landscape of South Africa.Methods: The method of the study involved in-depth interviews and thematic analysis. The study employed a qualitative exploratory multiple-case study. This article is based on data that were collected from a broader study that looked at the care and support of queer learners in a variety of high schools.Results: This article helps uncover the complexities of advocacy, assimilation, and the intersectionality of identity.Conclusion: Queer educators understand that their visibility in schools benefits LGBT school youth. Queer educators desire true acceptance and inclusion amongst their colleagues.Contribution: Building on the insights shared by the three educators, the study offers recommendations to enhance the care and support of queer educators in high school settings.
Out in the classroom: Self-disclosure as a ‘pedagogical tool’
Authors: Brown Anthony 
Published: September 2024

Background: In South African higher education, LGBTQ+-identifying educators often navigate heteronormative and cisnormative spaces that marginalise their identities. Self-disclosure by LGBTQ+ educators have the potential to disrupt these norms and foster inclusivity, but it also carries personal and professional risks.Objectives: This autoethnographic study explores the transformative potential and challenges of self-disclosure by LGBTQ+ educators in South African higher education, focusing on my experiences as a gay professor.Methods: The study employs an autoethnographic approach, drawing on my personal narratives, reflections and artefacts related to my experiences of self-disclosure in the classroom. The data were analysed using a thematic analysis approach, informed by critical and transgressive pedagogies and queer theory.Results: Disclosure about my sexual orientation confused students’ assumptions that I am heterosexual. It challenged their prejudices about LGBTQ+ identities. It also created opportunities for critical dialogue and fostered a more inclusive classroom environment. However, this article also reveals the institutional and social barriers that continue to marginalise LGBTQ+ voices in South African education.Conclusions: Self-disclosure by LGBTQ+ educators can be a transformative pedagogical tool for challenging oppressive norms and fostering social justice in education. However, it is a complex and risky process that requires institutional support and personal resilience.Contribution: The study highlights the need for further research on LGBTQ+ educators’ experiences and pedagogical practices in South Africa and beyond.

Published: September 2024

Background:
Acute lymphoblastic leukemia (ALL) has survival rates of greater than 90% in developed nations. However, various sociodemographic factors adversely affect outcome rates in low- and middle-income countries (LMICs).

Objective:
To study induction outcome of ALL and various factors affecting it.

Methods:
This was a prospective cohort study which enrolled 86 children up to the age of 18 years with newly diagnosed ALL registered in newly established pediatric hematology and oncology division over the duration of 3 years. Sociodemographic and clinical data was collected. Outcome was assessed using morphological remission, minimal residual disease (MRD) and mortality rate.

Results:
Of the 170 children with malignancies registered, 86 were ALL. Mean age was 7.09 ± 4.07 years and the M: F ratio of 1.32:1. Sixteen (38.09%) of them had severe acute malnutrition and another 16 (38.09%) had moderate acute malnutrition. Thirty (68.18%) children over 5 years were undernourished. Seventy-four (86.05%) were B-ALL and 12 (13.95%) T-ALL. In total, 28.77% had WBC counts greater than 50 × 109/L. t (12;21) was the most common cytogenetic abnormality. Majority (60.46%) of the patients belonged to lower socioeconomic status. Seventy-one (93.42%) patients completed induction of which 100% attained morphological remission and 64 (90.14%) were MRD negative. There were five mortalities, three (60%) due to sepsis and 2 (40%) due to hemophagocytic lymphohistiocytosis. Fifty (65.78%) children had morbidities during induction, febrile neutropenia being the commonest.

Conclusions:
Successful induction outcome rates at par with high-income countries can be achieved even in resource-limited settings of LMIC with support from government and NGOs. Decentralized cancer care centers can eﬀectively pave the way in reducing cancer mortality in children of lower socioeconomic status residing in rural areas.

Authors: Liu Shasha , Wang Yao , Kang Tingting , Lv Wenhao , Ma Ruonan , Yu Ying , Yin Lianrong 
Published: September 2024

Purpose:
To evaluate the long-term subjective and objective visual quality after implantation of a diffractive trifocal intraocular lens (IOL) in high myopic eyes.

Methods:
A total of 53 eyes from 38 patients with high myopia who underwent phacoemulsification and trifocal IOL implantation were investigated. The visual acuity, contrast sensitivity, diopter, defocus curve, and objective visual quality at 1 month, 3 months, 1 year, and 2 years after surgery, as well as the satisfaction questionnaire and VF-14 scale, were statistically analyzed.

Results:
The average age was 53.14 ± 4.70 years. The average preoperative spherical equivalent was −10.77 ± 3.98 D. Two years after surgery, 94.3% of the patients achieved an uncorrected distance visual acuity of 0.1 (LogMAR), and 84.9% and 94.3% of the patients had SE within ±0.50 D and ±1.0 D, respectively. The defocus curve was smooth and at a high value within the range of 0 D to −2.50 D. In CS or objective visual quality, there was no significant difference at 3 months, 1 year, and 2 years after operation (all P > 0.05). The rate of spectacle independence was 100%. The proportion of patients with moderate or severe glare and halo was 10.5% and 13.2%, respectively. Furthermore, 23.7%, 26.3%, and 18.4% of the patients had difficulties in reading small font, doing delicate tasks, and driving or riding at night, respectively.

Conclusion:
The diffractive trifocal IOL implantation provided good distance, intermediate, and near uncorrected visual acuity for patients with cataracts and high myopia. It was safe, effective, predictable, and stable. It provided long-term good visual quality after surgery, with high spectacle independence and high patient satisfaction.
Amniotic membrane graft (AMG) for persistent epithelial defects following infective corneal ulcers and keratitis – A systematic review
Authors: Thevi Thanigasalam , Abas Adinegara L , Dua Harminder S 
Published: September 2024

Abstract
Management of nonhealing corneal ulcers is challenging as it can lead to complications such as melting, descemetocele, and perforation, which can be prevented by amniotic membrane graft (AMG). The absence of any review (English language) on AMG for corneal ulcers prompted us to conduct this review. We looked for clinical trials (randomized and controlled) on the effect of AMG combined with other treatments, through various search engines utilizing the terms amniotic membrane and corneal ulcer. All patients who received AMG and/or conventional medication were included. Risk of bias tools derived from Cochrane collaboration were used to ascertain the standard and quality of the trials. Visual acuity and epithelial healing time were the main outcome measures studied. Three trials were finally selected for analysis. AMG was noted to be associated with better uncorrected visual acuity and reduction in neovascularization. There was no difference in best corrected visual acuity, epithelial healing time, and corneal opacity. There is evidence that the use of AMG is associated with improved uncorrected visual acuity as well as reduction in neovascularization of the cornea among patients with corneal ulcers, but there was no improvement in epithelial healing time or corneal opacity. Further multicenter randomized controlled trials are needed to elicit the beneficial effects of the intervention and augment the validity of this review.

Authors: Al-Balasi Abdulkareem K. , Omer Dina M. 
Published: September 2024

Abstract

Background and Aims:
Hearing loss (HL) is a significant public health concern. Research on its prevalence and pattern are crucial for understanding its causes, identifying high-risk populations, developing prevention strategies, and ultimately, improving the quality of life for people with HL. Therefore, this study aims to investigate the prevalence, pattern, and causes (etiology) of HL among patients attending our ENT Hospital.

Study Design:
This study was a retrospective review of existing medical records of patients from a Tertiary ENT Hospital in Yemen to determine the prevalence, patterns, and causes of HL among patients attending ENT centers.

Results:
A total of 951 patients were included in this study. The prevalence of HL was found to be 29.7%. The most commonly affected age group was 11–20 years old, with conductive HL being the most frequent subtype 65.1%. Sensorineural HL followed at 27.8%, and mixed HL was present in 7.1% of patients. Chronic suppurative otitis media (CSOM) 29.5% was identified as the most common cause of HL, followed by otitis media with effusion and wax impaction.

Conclusion:
HL is a significant public health concern in developing countries. CSOM is a major contributor to HL in this population, and age plays a role in the type of HL experienced.

Published: September 2024

The Covid-19 crisis has forced educational institutions to conduct online learning. However, the technology readiness and acceptance of the human resource to this shift towards distance education via Learning Management System (LMS) remained in question. This is where the gap lies between the govt’s policy and LMS implementation reality. The current study aims to explore the Moodle LMS acceptance among undergraduate students throughout the Archipelago Indonesia during the pandemic and beyond by adopting a Unified Theory of Acceptance and Usage of Technologies (UTAUT) model to better explain the students' behavioral intentions. Data has been gathered from 510 undergraduate students via online questionnaire with the help of Google Form. We used adapted questionnaire and tried it out before being administered. Using the Partial Least Squares - Structural Equation Modelling to analyze the data, this study has found that the original UTAUT constructs, except for effort expectancy and facilitating conditions, can influence the intention of using the Moodle LMS. This study also has revealed that both computer self-efficacy and other-efficacy directly affect the intention of utilizing Moodle application for e-learning platform. Furthermore, experience positively moderated computer-self efficacy and negatively other-efficacy as hypothesized. The findings indicate that Performance Expectancy and Social Influences are confirmed to have contributed to UTAUT Model, while Effort Expectancy and Facilitating Condition are not. In addition, constructs within Social Cognitive Theory, i.e. Other Efficacy, Computer Self Efficacy and Behavioral Intention are totally confirmed both directly and indirectly. With regard to the findings, practical recommendations have also been given at the end.

Abstract. Gully erosion can be combatted in severely affected regions like sub-Saharan Africa using various low-cost interventions that are accessible to affected farmers. For successful implementation, however, biophysical evidence of intervention effectiveness needs to be validated against the interests and priorities of local communities. Working with farmers in a watershed in southern Ethiopia, we investigated (a) the effectiveness of low-cost gully rehabilitation measures to reduce soil loss and upward expansion of gully heads; (b) how farmers and communities view gully interventions; and (c) whether involving farmers in on-farm field trials to demonstrate gully interventions improves uptake, knowledge, and perceptions of their capacity to act. On-farm field experiments, key-informant interviews, focus group discussions, and household surveys were used to collect and analyse data. Three gully treatments were explored, all with riprap, one with grass planting, and one with grass planting and check-dam integration. Over a period of 26 months, these low-cost practices ceased measurable gully head expansion, whereas untreated gullies had a mean upward expansion of 671 cm, resulting in a calculated soil loss of 11.0 t. Farmers had a positive view of all gully rehabilitation measures explored. Ongoing rehabilitation activities and on-farm trials influenced the knowledge and understanding of similar gully treatments among survey respondents. On-farm experiments and field day demonstrations empowered farmers to act, addressing pessimism from some respondents about their capacity to do so.

Published: September 2024

Introduction. Despite extensive studies devoted to comprehensive comparisons of the expression of mRNA, proteins, mutations in cell cultures and tissue samples of breast cancer, there is insufficient data on the comparability of their receptor apparatus.The purpose of the study was to determine changes in receptor expression levels in a cell culture obtained from a sample of the luminal B over five passages.Materials and methods. A cell culture was obtained. Estrogen and Ki‑67, pancytokeratin and vimentin were analyzed over five passages. Paraffin blocks were prepared from part of the material for immunohistochemical analysis.Results and discussion. A culture was obtained with high levels of Ki‑67 and estrogen expression during the first three passages. The cells maintained their epithelial nature throughout the culture. Perhaps this culture can demonstrate the processes occurring during regional metastasis. This is evidenced by the detection of tumor cells expressing vimentin from the first to the fourth passage. Thus, studying the processes occurring in in vitro models will help to come closer to understanding the processes in the biology of breast cancer and clarify the nature of the heterogeneity of this disease.Conclusions. Studying the differences between primary culture cells and tumor tissue samples will provide an effective in vitro model.
