Published: November 2021

AbstractAccurate positioning and navigation play a vital role in vehicle-related applications, such as autonomous driving and precision agriculture. With the rapid development of Global Navigation Satellite Systems (GNSS), Precise Point Positioning (PPP) technique, as a global positioning solution, has been widely applied due to its convenient operation. Nevertheless, the performance of PPP is severely affected by signal interference, especially in GNSS-challenged environments. Inertial Navigation System (INS) aided GNSS can significantly improve the continuity and accuracy of navigation in harsh environments, but suffers from degradation during GNSS outages. LiDAR (Laser Imaging, Detection, and Ranging)-Inertial Odometry (LIO), which has performed well in local navigation, can restrain the divergence of Inertial Measurement Units (IMU). However, in long-range navigation, error accumulation is inevitable if no external aids are applied. To improve vehicle navigation performance, we proposed a tightly coupled GNSS PPP/INS/LiDAR (GIL) integration method, which tightly integrates the raw measurements from multi-GNSS PPP, Micro-Electro-Mechanical System (MEMS)-IMU, and LiDAR to achieve high-accuracy and reliable navigation in urban environments. Several experiments were conducted to evaluate this method. The results indicate that in comparison with the multi-GNSS PPP/INS tightly coupled solution the positioning Root-Mean-Square Errors (RMSEs) of the proposed GIL method have the improvements of 63.0%, 51.3%, and 62.2% in east, north, and vertical components, respectively. The GIL method can achieve decimeter-level positioning accuracy in GNSS partly-blocked environment (i.e., the environment with GNSS signals partly-blocked) and meter-level positioning accuracy in GNSS difficult environment (i.e., the environment with GNSS hardly used). Besides, the accuracy of velocity and attitude estimation can also be enhanced with the GIL method.

Abstract
Background
Unilateral lower limb swelling has wide differential diagnoses with varying treatment plans, requiring an early and accurate diagnosis. Doppler ultrasound offers an extensive examination of the vascular system providing a platform for diagnosis and avoidance of unnecessary invasive procedures. Thus, it becomes pertinent to ensure that all the sonographic information required for the accurate diagnosis of a swollen lower limb is documented and critically analyzed in our setting, hence this study.

Results
The records of a total of 151 patients with acute unilateral lower limb swelling were retrieved, females constituted the majority (51.7%). The overall mean age was 58.70 ± 16.71 years. Statistical significance was specified at p ≤ 0.05 for this study. The males were on the average 1.86 years younger than the female, but this difference was not statistically significant (p = 0.495). Patients older than 60 years constituted the majority 72 (47.7%) followed by the 40–60-year age category 61 (40.4%), and the left lower limb was affected more often 82 (54.3%). Multiple inguinal lymphadenopathy 82 (35.7%) and edema with thickened skin and subcutaneous layers 67 (29.1%) were the two most recurrent ultrasound features. There was no significant association between the sonographic features and the diagnoses made for acute unilateral lower limb swelling, except for the feature of edema with thickened skin and subcutaneous layers (p = 0.004) and the diagnosis of cellulitis (p = 0.047) that increased significantly with age.

Conclusion
Multiple inguinal lymphadenopathy and edema of the skin and subcutaneous layers were the most recurrent ultrasound features with cellulitis as the main diagnosis for acute unilateral lower limb swelling in our setting. Edema with thickened skin and subcutaneous layers and cellulitis both increased significantly with age. Sonographers, sonologists, and radiologists must be on the look-out for these in their practices.

AbstractTumors are one of the leading causes to death in pet dogs among diseases. The tumor incidence of pet dogs has been increasing, raising widespread concern. In this study, retrospective analysis was performed with 246 tumor cases registered in Xi’an Animal Hospital, Northwest A&F University from 2009 to 2018. Correlations of sex, age and breed with tumor incidences were evaluated. The results showed that reproductive system tumors occupied the highest proportion (39.84%), followed by cutaneous tumors (28.05%), digestive tumors (18.70%) and ocular tumor (4.47%). Among the reproductive system tumors, breast tumors are the most common tumor in female pet dogs, especially for Pekingese (11.43%). Female dogs with high susceptibility to breast tumors were at the ages of 6–18 years old. As far as cutaneous tumors were concerned, the male pet dogs at all ages, particularly Golden Retrievers (17.39%), showed a high incidence. By contrast, male Samoyed aged from 4 to 13 years had the highest incidence (15.22%) of digestive tumors. In addition, pet dogs with ocular tumors mainly happened at the ages of 0–1 years and 6–13 years. Collectively, our findings are significant to develop effective measures of medical surveillance for pet dogs’ health and will provide insights for comparative oncology.
Far-offset detection of normal modes and diving waves: A case study from the Valhall Field, southern North Sea
Authors: Borges Filipe , Landrø Martin 
Published: November 2021

The use of permanent arrays for continuous reservoir monitoring has become a reality in the past decades, with Ekofisk and Valhall being its flagships. One of the possibilities when such a solution is available is to passively record data while acquisitions with an active source are ongoing in nearby areas. These recordings might contain ultrafar-offset data (more than 30 km), which are hardly used in standard reservoir exploration and monitoring because they are mostly a combination of normal modes, deep reflections, and diving waves. We present data from the Valhall life-of-field seismic array, recorded while an active seismic survey was acquired at Ekofisk, in April 2014. Despite the lack of control on source firing time and position, analysis of the data indicates that the normal modes are remarkably clear, overcoming the ambient noise in the field. The normal modes can be well explained by a two-layer acoustic model, whereas a combination of diving waves and refracted waves can be fairly well reproduced with a regional 1D velocity model. We suggest a method to use far-offset recordings to monitor changes in shallow sediments between source and receivers, with and without a coherent seismic source in the area.
Neurology in the psychiatric patient: how to think about differentials in altered mental status and diagnoses not to miss
Authors: McLaughlin Jonathan , Young Tim 
Published: November 2021

SUMMARYA wide variety of neurological conditions may present first to a psychiatrist and it is important to be aware of these in differential diagnosis. A careful history, examination and a broad differential diagnosis can help set up an appropriate management plan – with room to change if things change in unexpected ways. In this article we explore common ground shared by psychiatry and neurology and show how incorporation of neurological knowledge can improve the practice of psychiatry. Using four fictional case vignettes of altered mental status we explore important neurological differential diagnoses which could present to the Psychiatrist.

PURPOSE To evaluate the clinical outcomes in patients with cervical cancer with limited residual disease at brachytherapy (BT) treated with point-based dose prescription. METHODS Patients with locally advanced squamous cell carcinoma of the cervix treated with computed tomography (CT)-based intracavitary BT were considered for analysis. Patients with good response to external beam radiotherapy and limited residual disease suitable for intracavitary BT alone were included. Postapplication CT scans were performed before each fraction and individual plans were made for each session. The dose per fraction was 9Gy high dose rate, prescribed to point-A. Two sessions were planned, 1 week apart. The organs at risk were contoured, and cumulative dose-volume histograms were computed. Local control, pelvic control, disease-free survival, and overall survival were evaluated and late toxicities were documented. RESULTS Four hundred ninety patients were included. Overall, 79.8% had International Federation of Gynecology and Obstetrics (FIGO) stage IB2 to IIB disease and 20.2% had stage III to IVA disease. Median dose at point A (EQD210Gy) was 74.4 Gy (interquartile range [IQR] 72.3-74.5 Gy) and median D2cc (EQD23Gy) for bladder, rectum, and sigmoid were 82.5 Gy (IQR, 65.5-90.8 Gy), 66.5 Gy (IQR, 60.7-75.7 Gy), and 54.1 Gy (IQR, 50.5-77.3 Gy), respectively. At a median follow-up of 62 (IQR, 33-87) months, the 5-year local and pelvic control rates were 90.1% and 88.3%, respectively. The 5-year disease-free survival was 80% and overall survival was 88%. Rates of grade 3-4 bladder and rectosigmoid toxicities were 6.93% and 4.08%, respectively. CONCLUSION In patients with limited residual disease at BT, point-based dose prescription with CT planning results in good local control and acceptable toxicity. In a resource-constrained setting, patients may be triaged to receive point-based BT or magnetic resonance imaging–guided adaptive BT depending on the extent of residual disease.

PURPOSE In 2015, ASCO established a program designed to support medical interest in cancer-related careers: Oncology Student Interest Groups (OSIGs). The purpose of this study was to describe the characteristics of current student leaders of ASCO-sponsored OSIGs and their perceptions of cancer-related careers. METHODS We reviewed the list of all ASCO-sponsored OSIGs between 2015 and 2021. For this study, we focused on OSIGs that were sponsored during the 2019-2020 academic year. All student leaders of the 89 OSIGs active in that academic year were invited to participate. RESULTS The number of groups has more than tripled in the 6 years since the program's inception. The number of international groups has increased to become almost one fifth of all OSIGs; however, the range of countries represented remains limited. The majority of OSIG leaders were female. Eighty two percent of OSIGs were returning members, with most of their leaders being registered ASCO student members. Almost all participants reported an interest in pursuing a cancer-related specialty. Only a minority (14.8%) reported having a family member working in a cancer-related career. However, 85% reported having experience with a cancer diagnosis in their family. The majority of the respondents had a favorable perception of medical oncology as a specialty. Participants reported the highest levels of interest in medical oncology and pediatric oncology. CONCLUSION The number of ASCO-sponsored OSIGs has steadily increased since the creation of the program. Most participants reported an interest in pursuing a cancer-related career. To our knowledge, this study is the first to provide insights into the makeup of this program around the world. Additional efforts are needed to increase the global reach of the program, particularly in low-income countries.
Wittgenstein's Tractatus as Poetic Philosophy and Philosophical Poetics
Authors: Bremer Józef 
Published: November 2021

Abstract
This article argues that it is helpful to discuss the logico-philosophical contents of Wittgenstein's Tractatus Logico-Philosophicus in terms that confront the poetic and literary qualities of its form and style. To begin with, it analyzes Wittgenstein's short remarks about expression as manifested in the “tone” of Georg Trakl's poetry and the “ineffability” of Ludwig Uhland's poem “Count Eberhard's Hawthorn.” Then it proceeds to consider his exchange of letters with Gottlob Frege about the form and style of the Tractatus. The final part of the article considers such Tractarian metaphors as “showing and saying,” “logical space,” “reflecting the world as in a mirror,” “ineffability,” and “climbing and throwing away a ladder.” The proposed examination concentrates mainly on the distinction—but also the connection—between what, through language as used in both philosophy and poetry, can be said and what can be shown, this being one of the central themes of the Tractatus itself. It is then claimed that the roots of Wittgenstein's later understanding of both “ordinary language” and the connection between philosophy, poetry, and the ethical form of one's life are already present in his first period of creativity.
Guo Xi on Painting the Invisible Gaze of the Dao
Authors: Chai David 
Published: November 2021

Abstract
For the Song dynasty painter and theorist Guo Xi, Daoism runs like veins through his Lofty Appeal of Forests and Streams, helping it become one of the greatest works of landscape painting theory in China. This essay explores the influence Laozi and Zhuangzi had on Guo Xi's thought, paying particular attention to the latter's implementation of spirit, nature, and incompleteness. Guo Xi succeeded in giving these Daoist themes an aesthetic significance that had yet to be fully realized by his predecessors, while expounding them in a manner that remained faithful to the texts from which they were drawn. While Guo Xi was not the first person in China to employ the principles of Daoist philosophy in their discourse on landscape painting, his ability to synthesize them into a cohesive representation of the invisible gaze of the Dao led to his becoming one of the most eminent painters and aesthetic theorists in the history of Chinese aesthetics.
Marginalia Transcription and Scholarly Culture in the Qing Dynasty
Authors: Yinzong Wei 
Published: November 2021

Abstract
In the Qing, transcription of marginalia became common scholarly practice, involving a number of different people who created a new reading culture. This article follows the marginalia trail of scholar and calligrapher He Zhuo 何焯 through various transcribers and others involved in the process: He's disciples, later generations of scholars, bibliophiles, calligraphers, and booksellers. Connected through He's and others' marginalia across time and space, these transcribers established a network for the efficient transmission of information, knowledge, and thought. Transcription of such marginalia created a unique book culture that shaped scholarship, thought, and society in the Qing and produced critical texts that are still read today.

Published: November 2021

Background Although rabies in dog bite patients is preventable through timely initiation of post-exposure prophylaxis (PEP), a number of barriers to achieving PEP exist. This study investigated the delays to initiation of PEP among dog bite patients in the emergency departments of two PEP centers in Uganda. Methods A cross-sectional study was conducted among dog-bite patients that presented to two selected rabies PEP centers. A semi-structured questionnaire was used to collect data. Delay to receive PEP was defined as reporting for PEP beyond 24 hours after the bite event. Generalized linear models were used to calculate prevalence ratios and the 95% confidence intervals as a measure of association between delay and patient factors. Results Out of 376 participants, just over half (53.5%) were males. The majority of participants (54.0%) were 15 years or older and 28.5% had no formal education. Just over three-quarters (77.9%) had category II dog bite wounds. Nearly 40% delayed to receive PEP, and median (inter quartile range) lag time between bite event and seeking medical care of 18 (41) hours. Compared to education level of secondary or above, patients with no formal education (adj. PR=4.06, 95% CI: 2.69 - 6.10) or primary education (adj.PR=2.15, 95% CI: 1.37 - 3.35), belonging to the lowest socio-economic tertile as compared to the highest (adj.PR=1.58, 95% CI: 1.10 - 2.28), knowing the owner of the biting dog (adj.PR=1.30, 95% CI: 1.02 - 1.65) and having category II wounds (adj.PR=2.31, 95% CI: 1.43 - 3.71) were all associated with delayed presentation for PEP. Conclusions and recommendations Delays to receive PEP are common and are associated with poor level of education or low socio-economic status, knowledge of who the dog owner is and less severity of bite wounds. Seeking care irrespective of wound severity or knowledge of dog owner should be promoted.

Background : This research aimed to examine and analyze risk factors for death, hematologic parameters and coagulation in COVID-19 patients at RSUD Dr. Soetomo Surabaya, one of the referral centers for probable COVID-19 patient cases in East Java. Method : This was a retrospective analytical study by taking secondary data on patients with probable COVID-19 cases who were treated in hospital isolation rooms from May to September, 2020. Result : Of 538 probable COVID-19 patients, 217 were tested positive, with an average age of 52.11±13.12 years, and there were 38 death cases. Hematologic parameters, such as white blood cell, neutrophil and lymphocyte counts, showed significantly different result in the deceased group. On the other hand, coagulation parameters, consisting of D-dimer, CRP, PT, and aPTT showed significantly similar value in the deceased group. Univariate analysis concluded that chronic kidney disease, diabetes mellitus, coronary heart disease, WBC, NLR, and PPT counts could predict the mortality, while multivariate analysis revealed that coronary heart disease was the only significant independent predictor of mortality. Conclusion : This research shows that hematologic and coagulation parameters increased in the majority of COVID-19 patients and the deceased group. While the number of neutrophils and WBC increases, the number of lymphocytes decreases significantly as the disease gets more severe.. Coronary heart disease is an independent predictor of mortality.
Identifying priorities for the collection and use of data related to community first response and out-of-hospital cardiac arrest: protocol for a nominal group technique study
Authors: Keegan Dylan , Heffernan Eithne , McSharry Jenny , Barry Tomás , Masterson Siobhán 
Published: November 2021

Introduction: Out-of-hospital cardiac arrest (OHCA) is a devastating health event that affects over 2000 people each year in Ireland. Survival rate is low, but immediate intervention and initiation of cardiopulmonary resuscitation (CPR) and administration of an automated external defibrillator (AED) can increase chances of survival. It is not always possible for the emergency medical services (EMS) to reach OHCA cases quickly. As such, volunteers, including lay and professional responders (e.g. off-duty paramedics and fire-fighters), trained in CPR and AED use, are mobilised by the EMS to respond locally to prehospital medical emergencies (e.g. OHCA and stroke). This is known as community first response (CFR). Data on the impact of CFR interventions are limited. This research aims to identify the most important CFR data to collect and analyse, the most important uses of CFR data, as well as barriers and facilitators to data collection and use. This can inform policies to optimise the practice of CFR in Ireland. Methods: The nominal group technique (NGT) is a structured consensus process where key stakeholders (e.g. CFR volunteers, clinicians, EMS personnel, and patients/relatives) develop a set of prioritised recommendations. This study will employ the NGT, incorporating an online survey and online consensus meeting, to develop a priority list for the collection and use of CFR data in Ireland. Stakeholder responses will also identify barriers and facilitators to data collection and use, as well as indicators that improvements to these processes have been achieved. The maximum sample size for the NGT will be 20 participants to ensure sufficient representation from stakeholder groups. Discussion: This study, employing the NGT, will consult key stakeholders to establish CFR data collection, analysis, and use priorities. Results from this study will inform CFR research, practice, and policy, to improve the national CFR service model and inform international response programs.
Implementation of a software defined FLISR solution on an active distribution grid
Authors: Leniston Darren , Ryan David , Power Clem , Hayes Paul , Davy Steven 
Published: November 2021

Background: The resiliency of the distribution grid is of increasing concern to the distribution system operator (DSO) due to factors such as climate change and the resulting faults caused by inclement weather conditions, leading to service disruption to consumers. Loss of service negatively affects key performance indicators (KPI) of the DSO, such as customer minutes lost (CML) and customer interruptions (CI), leading to financial penalties imposed by the regulator. Methods: In this paper we propose a software-driven Fault Location, Isolation and Service Restoration (FLISR) solution, leveraging modern software and communication technologies married with the DSO's existing infrastructure, to aid fault detection and resolution, with the aim of reducing CMLs & CIs and curtailing the financial penalties incurred. Results: The proposed FLISR solution was trialled in an area of south-east Ireland which sees a higher count of service loss as compared to more inland areas, providing an ideal environment to gauge the effectiveness of the solution. It was found that the solution generated outputs that could potentially lead to the resolution of fault events faster than the current systems in place by the DSO. Conclusions: Based on the results gathered from operating the FLISR solution on an active grid, it has demonstrated that leveraging modern software technologies in tandem with existing grid infrastructure benefits the DSO with reference to grid management and operations and the customer in terms of quality of service site.
