Published: September 2024

Drones have witnessed extensive popularity among diverse smart applications, and visual Simultaneous Localization and Mapping (SLAM) technology is commonly used to estimate the six-degrees-of-freedom pose for drone flight control systems. However, traditional image-based SLAM cannot ensure the flight safety of drones, especially in challenging environments such as high-speed flight and high dynamic range scenarios. The event camera, a new vision sensor, holds the potential to enable drones to overcome these challenging scenarios if fused with the image-based SLAM. Unfortunately, the computational demands of event-image fusion SLAM have grown manifold compared with image-based SLAM. Existing research on visual SLAM acceleration cannot achieve real-time operation of event-image fusion SLAM on on-board computing platforms for drones. To fill this gap, we present
TrinitySLAM
, a high-accuracy, real-time, low-energy consumption event-image fusion SLAM acceleration framework utilizing Xilinx Zynq, an on-board heterogeneous computing platform. The key innovations of
TrinitySLAM
include a fine-grained computation allocation strategy, several novel hardware–software co-acceleration designs, and an efficient data exchange mechanism. We fully implement
TrinitySLAM
on the latest Zynq UltraScale+ platform and evaluate its performance on one custom-made drone dataset and four official datasets covering various scenarios. Comprehensive experiments show that
TrinitySLAM
improves the pose estimation accuracy by 28% with half end-to-end latency and 1.2× energy consumption reduction compared with the most comparable state-of-the-art heterogeneous computing platform acceleration baseline.
Wideband coupled-line BPF with high-selectivity based on parallel transmission line signal interference technique for cellular base stations applications
Authors: Firmli Maroua , Zatni Abdelkarim 
Published: September 2024

This paper presents a novel approach involving a modified wideband parallel coupled line bandpass filter (BPF). The proposed modification aims to achieve both enhanced skirt selectivity and simplified configuration, while ensuring the prevention from discontinuities between adjacent segments. The improvements in the performance of the filter’s structure are achieved through the integration of a signal-interference filtering model using parallel transmission line with distinct impedance values and electrical lengths at the input/output of the filter. This integration gives rise to the generation of multiple transmission zeros (TZs), thereby bolstering attenuation within both in-band and out-of-band frequency ranges. For the purpose of concept validation, a 3𝑟𝑑 wideband band-pass filter with 𝑓0=2.45 Ghz, accompanied by a fractional bandwidth of 50% was designed and simulated using microstrip RO6010 substrate. The outcomes of the simulation exhibit good performance, characterized by minimal insertion loss, wide bandwidth and the presence of seven TZs within the passband, resulting in high selectivity and sharp stopband rejection level.

BACKGROUND:
Pursuing initial invasive or conservative management of chronic coronary disease (CCD) is a preference-sensitive decision that should include shared decision-making. Communicating the benefits of either approach is challenging, as individual patients rarely achieve the population-averaged outcomes reported in clinical trials. Our objective was to develop a patient decision aid (PDA) with patient-specific estimates of outcomes for initial invasive versus conservative management of CCD, based on the ISCHEMIA trial (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches).

METHODS:
This was a multiphase mixed-methods study using focus groups of outpatients with CCD, caregivers, clinicians, and researchers. Focus groups were held in Kansas City, MO and New York City, NY between September 2021 and June 2022. Patients with CCD were included if they had a positive stress test within 1 year. Phase 1 focused on patient priorities for outcomes to guide treatment decisions. Phase 2 involved PDA development and refinement. Phase 3 involved further refinement and member checking. Key themes involving shared decision-making and treatment preferences were elicited from focus groups using a deductive approach to develop a PDA representing the outcomes most important to patients.

RESULTS:
Of 46 patient and caregiver participants, the mean age was 63.5 years, 53% were female, 61% were White, 24% were Black, and 9% were Hispanic. When deciding between treatments, participants valued shared decision-making but generally deferred decisions to clinicians. The outcomes most important to participants were survival and quality of life, followed by physical functioning and symptoms. To represent these outcomes, participants favored simple visualizations, such as a speedometer or health meter. When deciding between treatment options, participants preferred to use the PDA collaboratively with a clinician instead of as a stand-alone tool.

CONCLUSIONS:
Our novel, patient-centered approach to developing a PDA for CCD with patient-specific outcomes has the potential to rapidly translate clinical trial results to individual patients and support shared decision-making.
Investigating the effective temporal resolution in a task-based functional MRI experiment at 7 T MRI using a dynamic phantom
Authors: Baz Guy , Schmidt Rita 
Published: September 2024

Abstract
An increasing number of human fMRI studies aim to discern the time delays between evoked responses under different stimuli conditions in different brain regions. To achieve that, a primary goal is to acquire fMRI data with high sampling rates. This task is now possible with ultra-high field (≥7 T) MRI and the advancement of imaging acceleration methods. Consequently, it becomes imperative to understand what is the actual or effective temporal resolution (ETR) that is realized in given settings of an fMRI experiment. In this study, we utilized a dynamic phantom to reliably repeat a set of scans, generating a “ground truth” signal with controllable onset delays mimicking fMRI responses in a task-based block-designed fMRI. Here, we define the ETR and quantify a scan’s ETR using the dynamic phantom. The quantification was performed for various scanning parameters, including echo time (TE), repetition time (TR), voxel size, and contrast-to-noise ratio (CNR). We further show that combining data from multi-echo EPI can improve the ETR (i.e., reduce it). In addition, parameters of the fMRI paradigm were examined, including the blocks’ length and density. As tissue properties (e.g., level of iron deposition) affect the CNR and thus change the ETR, we examined the signal rise mimicking not only the cortex, but also the basal ganglia (known for its high iron deposition). Combining multi-echo data, the estimated ETR for the examined scans was 151 ms for a cortex-mimicking setup and 248 ms for a basal ganglia-mimicking setup, when scanning with a sampling time (i.e., TR) of 600 ms. Yet, a substantial penalty was paid when the CNR was low, in which case the ETR was even larger than the TR. A feasibility set of experiments was also designed to evaluate how the ETR is affected by physiological signal fluctuations and the variability of the hemodynamic response. This study shows the viability of studying time responses with fMRI, by demonstrating that a very short ETR can be achieved. However, it also emphasizes the need to examine the attainable ETR for a particular experiment.
The London Convention: Jurisdiction and Liability Issues
Authors: Barnes Richard 
Published: September 2024

Abstract
For most of human history, dumping of waste was out of sight and out of mind. The London Convention and its 1996 Protocol forms part of a wider network of instruments under the 1982 United Nations Convention on the Law of the Sea that seek to protect and preserve the marine environment. This regime has come under pressure from new activities, as well as from developments in other areas of law. This paper provides some reflections on the key challenges facing the London Convention regime in terms of its jurisdictional reach and liability mechanisms. Whilst the regime responded to new forms of dumping, questions remain about how it can be used to respond to situations like the Fukushima incident and whether monitoring and reporting of dumping is effective. Perhaps more challenging is the lack of progress in developing an effective liability regime comparable to other harmful activities like oil pollution.

Published: September 2024

Abstract
This paper draws on findings from a systemic review of work published globally on museums’ responses to the Covid-19 pandemic and recommendations for future development in the museum sector. This can be used to determine the best practices for museums, including how to create engaging digital content, boost cultural tourism using digital technologies, create new business models, and manage copyright and legal protection of digitized content. It can be used to inform museums across Vietnam and beyond about the best practices internationally for Covid recovery by showing what published studies globally state about future practices to ensure the sustainability of museums. It also outlines an ethics of digitization concerning access to digital technologies and general understandings of the ‘correct’ use of digital content. This can be used as a ‘roadmap’ for museum professionals and fills a needs gap in Vietnam on digital culture policy, digital skills, and knowledge on how to manage legal and copyright issues with digital content. Overall, this paper can assist the national museum sector navigate a digital transition.

Published: September 2024

Background Hydatid disease is a parasitic infection seen in endemic areas. Musculoskeletal hydatid disease is rarely reported. Purpose To describe the magnetic resonance imaging (MRI) features of musculoskeletal hydatid disease and to highlight the specific findings in the diagnosis of hydatid cysts. Material and Methods The MRI scans of 29 cases diagnosed as musculoskeletal hydatid disease between 2000 and 2022 were retrospectively analyzed. The localization, size, appearance (unilocular or multilocular), signal characteristics, rim sign, presence of internal septa and membrane, and gadolinium enhancement pattern of hydatid cysts were evaluated. Results A total of 29 patients diagnosed with hydatid cyst were included in the study. Of the lesions, 18 were localized in bone and 11 were in soft tissue. The bone hydatid cysts on MRI showed heterogeneous low to intermediate signal intensity on T1-weighted images and high signal intensity on T2-weighted images in the medullary bone. In 15/18 patients, there was also cortical destruction and extension into the adjacent soft tissue planes. In 8/11 cases where the cyst was located in muscle tissue, the “cyst or cysts within a cyst” appearance was observed on MRI. The rim sign was observed in 7/11 cases and the “water lily” sign was noted in 2/11 cases. Conclusion MRI provides valuable information for the diagnosis of hydatid disease with its distinctive imaging features. Knowledge of the different patterns of hydatid cysts on MRI may be helpful in the diagnosis of this disease.

National Stock Exchange: Failure of Corporate Governance
Authors: Mehta Sunita , Mahapatra Mousumi Singha , Mishra Ram Kumar 
Published: September 2024

The case explores the corporate governance challenges that arose at the National Stock Exchange (NSE), India’s leading stock exchange. Chitra Ramkrishna served as the Managing Director and Chief Executive Officer (MD and CEO) of NSE from 2013 to 2016. In 2013, she was recognized by Fortune magazine as one of the most powerful women in business. In 2015, following a whistleblower’s complaint about preferential access given to certain brokers, Indian regulators launched investigations. Further allegations in September 2016 claimed that the appointment of Anand Subramanian, a close associate of Chitra Ramkrishna, violated the code of conduct. Anticipating potential dismissal over these alleged lapses, Ramkrishna resigned from the board in November 2016. Subsequent investigations revealed ongoing preferential access for select brokers during Ravi Narain’s tenure as NSE’s MD and CEO from 2010 to 2014. Narain had been a key mentor to Ramkrishna and strongly supported her appointment as CEO. It was also discovered that Ramkrishna continued to share confidential NSE information with Subramanian even after his termination. Despite these serious irregularities, the NSE board remained notably inactive. This case is significant as it highlights the NSE board’s failure to uphold its core responsibilities, allowing misconduct and irregularities to persist. It concludes by presenting the dilemma NSE’s new CEO and board of directors faced: how to address investor concerns while enhancing the organization’s leadership and governance structure.

Authors: Tefera Temesgen , Alemu Tsegaye , Alano Abraham 
Published: September 2024

Background:Basic sanitation services and practices are crucial for the well-being and health of a community. However, little is known about the determinants of basic sanitation services in Ethiopia, particularly in the study area.Objectives:To identify the determinants of basic sanitation service coverage among households in the Shashogo district, Hadiya Zone, and Central Ethiopia in 2023.Methods:A case–control investigation was carried out in households in Shashogo District from August 8, 2023, to December 10, 2023. Ten Kebeles were chosen randomly from a total of 34 Kebeles in the district. A total of 579 households (193 cases and 386 controls) were included in the study. The data were gathered with pretested and structured questionnaires in digital form with a smartphone. The data were analyzed with SPSS. Independent t tests and regression models were used to determine predictors of basic sanitation services.Results:The mean (±SD) age of the study participants was 38.2 (±8.9) years. After controlling for confounders in the multivariate analysis, the adoption of improved latrine services among households was found to be associated with greater average monthly income (AOR = 1.841, 95% CI (1.043, 3.251)), the study respondents who had access to the necessary materials for latrine construction/upgrade were approximately 3.5 times more likely to adopt improved latrine services among households with (AOR = 3.477 (95% CI = 1.314, 9.202) than among those who lacked access to the necessary materials for latrine construction, the study respondents who had training in sanitation and hygiene (AOR = 4.744, 95% CI (2.984, 7.542)) and who had sufficient knowledge about the adoption of improved latrine services (AOR = 2.020, 95% CI (1.125, 3.628)) were found to be determinants of the adoption of improved latrine services among households.Conclusion:This study revealed that economics, knowledge, attitudes and practices, infrastructure, and culture were identified as determinants of the adoption of improved latrines in the study area. Poor sanitation significantly impacts economic, social, environmental and many other direct and indirect impacts on the well-being of citizens. Therefore, policies on sanitation and contextual initiatives and focused actions are needed by stakeholders and policy implementers to improve knowledge gaps, access to necessary materials and the income capacity of those lagging to adopt services.

Introduction E-cigarettes and heated tobacco products (HTPs) are gaining worldwide significance. The tobacco industry is promoting these products as healthier alternatives to conventional cigarettes. Methods In this four-arm crossover study, we examined the acute effects of cigarette smoking, vaping IQOS, or vaping e-cigarettes (with or without nicotine) on hemodynamics, arterial stiffness, and small airways. Twenty subjects (10 male, 10 female), all occasional smokers, completed each study arm. There was at least a 48 h washout period before each test day. Arterial stiffness and peripheral and central hemodynamics were assessed using Mobil-O-Graph™ (I.E.M., Germany), whereas tremoFlo® c-100 (Thoracic Medical Systems Inc) was used to evaluate the effects on the small airways and resistance. Results Cigarettes, IQOS, e-cigarettes containing nicotine, and nicotine-free e-cigarettes had similar effects on peripheral and central hemodynamics as well as on arterial stiffness. We observed a significant increase in all parameters. However, only nicotine-containing products lead to increased bronchial obstruction, higher reactance, and a higher tidal volume. Conclusion Therefore, we concluded that cigarettes, IQOS, and e-cigarettes have similar effects on hemodynamics. No differences were observed between the nicotine-containing and nicotine-free e-cigarettes. All nicotine-containing products also influence small airways. These findings suggest that e-cigarettes and HTPs are not healthier alternatives than conventional cigarettes.
Multiple complex developmental disorder (MCDD): Did we throw the baby out with the bathwater too fast? A systematic review

Published: September 2024

Background Multiple complex developmental disorder (MCDD) manifests as early-onset impairment across different domains. Although it could appear as a transitional condition between autism and childhood-onset schizophrenia, interest in MCDD has progressively waned. This study attempts to discern MCDD current relevance to avoid “throwing the baby out with the bathwater” too fast. Methods All available studies published up to January 2024 were retrieved and evaluated following on the PRISMA guidelines for systematic reviews using the term “multiple complex developmental disorder” or “MCDD”, without any filter for study design nor year of publication. Results Only 16 studies were included and analyzed. Overall, a variable heterogeneity was observed in terms of country of investigation, study design, and clinical groups. Most of the included studies explored the construct of MCDD in developmental age, comparing MCDD mostly with autistic patients, and observing how the former group had higher levels of paranoia, illusions, and psychotic thoughts, whereas the latter showed more frequently difficulties in social interactions and stereotypical behaviors. Conclusion Overall, these results showed how progressive changes in diagnostic criteria over time led MCDD to be abandoned as nosographic construct, leaving perhaps a diagnostic void between autism and psychotic disorders that needs to be further studied.

Objectives: The microvasculature of the human meniscus has been previously described by Arnoczky and Warren. However, to date the qualitative and quantitative extra-articular vascular anatomy of the medial meniscus has not yet been characterized. Therefore, the purpose of our study was to perform a qualitative and quantitative anatomic study of the extra-articular medial meniscal vasculature and to introduce the novel “medial meniscal artery” (MMA), potentially providing future guidelines for the treatment of meniscal pathology. Methods: Thirty-three unpaired frozen human cadaveric knees were dissected. The popliteal artery was identified and cannulated with an angiocatheter. The arteries were perfused with a red acrylic paint solution allowing for improved visualization. Artery dimensions and distances were measured using a digital caliper. Perfused specimens were imaged with Computed Tomography scanning and segmented using software to identify vessels and repeat artery measurements. Results: The MMA was consistently identified in all specimens. In 26 of 33 (82%) specimens, the MMA branched directly from the popliteal artery, while in 6, the MMA shared a common trunk with the inferior medial genicular artery (IMGA). The MMA was easily distinguishable from the superior MGA, inferior MGA, and MGA, given its direct course to the medial joint line with terminal branches to the posterior horn of the medial meniscus and deep to the semimembranosus tendon. The MMA exhibited a consistently smaller vessel diameter relative to the genicular arteries. Conclusions: This is the first study identifying and quantitively describing the MMA in the human knee. The MMA can be identified consistently on gross anatomic dissection in patients of varying demographics. The findings of this study will provide future avenues of study toward understanding the medial meniscus vascularization and the genesis of potential degenerative changes when vascularization is poor. This will help to further refine diagnostic and treatment options for meniscus revascularization and compartment preservation. Additionally, this study may help define safe zones in the knee during posterior approaches, as well as furthering the base of knowledge for emerging vascular procedures such as genicular artery embolization. Further research is needed to identify and characterize the artery in vivo and to determine the MMA’s role in meniscus preservation.
