BackgroundRespiratory illness is a leading cause of morbidity in adults and the number one cause of mortality in children, yet billions of people lack access to medical imaging to assist in its diagnosis. Although ultrasound is highly sensitive and specific for respiratory illness such as pneumonia, its deployment is limited by a lack of sonographers. As a solution, we tested a standardised lung ultrasound volume sweep imaging (VSI) protocol based solely on external body landmarks performed by individuals without prior ultrasound experience after brief training. Each step in the VSI protocol is saved as a video clip for later interpretation by a specialist.MethodsDyspneic hospitalised patients were scanned by ultrasound naive operators after 2 hours of training using the lung ultrasound VSI protocol. Separate blinded readers interpreted both lung ultrasound VSI examinations and standard of care chest radiographs to ascertain the diagnostic value of lung VSI considering chest X-ray as the reference standard. Comparison to clinical diagnosis as documented in the medical record and CT (when available) were also performed. Readers offered a final interpretation of normal, abnormal, or indeterminate/borderline for each VSI examination, chest X-ray, and CT.ResultsOperators scanned 102 subjects (0–89 years old) for analysis. Lung VSI showed a sensitivity of 93% and a specificity of 91% for an abnormal chest X-ray and a sensitivity of 100% and a specificity of 93% for a clinical diagnosis of pneumonia. When any cases with an indeterminate rating on chest X-ray or ultrasound were excluded (n=38), VSI lung ultrasound showed 92% agreement with chest X-ray (Cohen’s κ 0.83 (0.68 to 0.97, p<0.0001)). Among cases with CT (n=21), when any ultrasound with an indeterminate rating was excluded (n=3), there was 100% agreement with VSI.ConclusionLung VSI performed by previously inexperienced ultrasound operators after brief training showed excellent agreement with chest X-ray and high sensitivity and specificity for a clinical diagnosis of pneumonia. Blinded readers were able to identify other respiratory diseases including pulmonary oedema and pleural effusion. Deployment of lung VSI could benefit the health of the global community.

Authors: Leisso Rachel , Jarrett Bridgid , Richter Rebecca , Miller Zachariah 
Published: November 2021

Haskap (Lonicera caerulea L.) is a relatively new berry crop in North America, and little research exists regarding its postharvest storage characteristics or storage life. Postharvest changes in berry quality, and principal factors limiting storage life at 1.1 °C and 95% relative humidity, were evaluated up to 14 days for three cultivars in 2019 and up to 28 days for six cultivars in 2020. Containerized berries were periodically assessed for soluble solids content (SSC), skin rupture force (SRF) (both 2019 and 2020) and flesh firmness, titratable acidity (TA), and Brix/acid ratio (B/A) (2020 only). External appearance was also evaluated both years, revealing berry shrivel as the primary factor negatively impacting visual appeal, followed distantly by low incidence of spoilage later in storage. All cultivars exhibited relatively constant postharvest SSC and decreasing SRF, flesh firmness, and TA (resulting in increasing B/A ratio). Postharvest quality differed slightly between years; relative SRF was consistent among cultivars while SSC was not. Some cultivars had a portion of shriveled berries at harvest, pointing to a need for cultivar-specific harvest indices. Mean days to slight shrivel for individual berries varied among cultivars evaluated, ranging from 7.5–21.9 d postharvest, with mean weight loss ranging from 1.2%–1.6% at this stage. Combined with group marketability estimates — set at a threshold of 10% severely shriveled berries — we estimate a storage life of 7–10 d for fresh haskaps. Additional research is needed to delineate maturation physiology and optimize harvest timing.
Optimal rendezvous on a line by location-aware robots in the presence of spies*

Published: November 2021

A set of mobile robots is placed at arbitrary points of an infinite line. The robots are equipped with GPS devices and they may communicate their positions on the line to a central authority. The collection contains an unknown subset of “spies”, i.e., byzantine robots, which are indistinguishable from the non-faulty ones. The set of the non-faulty robots needs to rendezvous in the shortest possible time in order to perform some task, while the byzantine robots may try to delay their rendezvous for as long as possible. The problem facing a central authority is to determine trajectories for all robots so as to minimize the time until all the non-faulty robots have met. The trajectories must be determined without knowledge of which robots are faulty. Our goal is to minimize the competitive ratio between the time required to achieve the first rendezvous of the non-faulty robots and the time required for such a rendezvous to occur under the assumption that the faulty robots are known at the start. In this paper, we give rendezvous algorithms with bounded competitive ratio, where the central authority is informed only of the set of initial robot positions, without knowing which ones or how many of them are faulty. In general, regardless of the number of faults [Formula: see text] it can be shown that there is an algorithm with bounded competitive ratio. Further, we are able to give a rendezvous algorithm with optimal competitive ratio provided that the number [Formula: see text] of faults is strictly less than [Formula: see text]. Note, however, that in general this algorithm does not give an estimate on the actual value of the competitive ratio. However, when an upper bound on the number of byzantine robots is known to the central authority, we can provide algorithms with constant competitive ratios and in some instances we are able to show that these algorithms are optimal. Moreover, in the cases where the number of faults is either [Formula: see text] or [Formula: see text] we are able to compute the competitive ratio of an optimal rendezvous algorithm, for a small number of robots.
Times as Task, Not Timing: Reconsidering Qoheleth’s Catalogue of the Times
Authors: Peterson Jesse M. 
Published: November 2021

Abstract
This essay examines Qoheleth’s Catalogue of the Times poem in Eccl 3:2–8. I argue that the two most common scholarly interpretations of the poem’s overall meaning fail to sufficiently account for its literary context and that an underdeveloped alternative reading is to be preferred. When we read the poem in light of two other closely related passages, 1:4–11 and 3:9–15, it becomes clear that a poem ostensibly about “time” is much less concerned with “timing” than is typically thought, but instead signifies Qoheleth’s frustration with the inevitable equilibrating tendency embedded into every human task.
Lot’s Struggle for “Masculinity”: Use, Function, and Ideology of Masculinity in the Lot Stories
Authors: Winkler Mathias 
Published: November 2021

Abstract
Taking a look at Lot through the lens of Biblical Masculinity Studies, we see him constantly trying to meet ideals of a performance of hegemonic masculinity but failing to do so. This paper uncovers masculinity as the motor of the narrative in the Lot stories, especially in Gen 19. The stories make fun of Lot and his offspring, the Moabites and Ammonites, as “failed” men. This paper analyses how this is achieved by the authors. Masculinity and masculine traits are artistically and deliberately used as a highly idealised background foil in order to highlight Lot’s failure. Furthermore, the authors’ point of view is highly ideological. They are in a superior and dominant position from which they portray Lot and his masculinity. They do this from safe distance, since they themselves are not represented in the stories by a character.
He Who Pays the Piper Calls the Tune: Big Data, Philanthrocapitalism, and the Demise of the Historical Study of Religions
Authors: Ambasciano Leonardo 
Published: November 2021

Abstract
The recent digital turn has had an unprecedented impact on the identity of the academic disciplines that study religions. Expectedly, this shift has brought about a dramatic change in the power dynamics between the main research actors and funders. In particular, historians and humanist scholars have taken the brunt, mostly replaced by data scientists, software engineers, statisticians, psychologists, anthropologists, and biologists alike. Consequently, multimillion-dollar projects aimed at testing historical hypotheses and massive agent-based simulations have been implemented on shaky methodological and epistemological grounds. Concurrently, in the aftermath of the 2008 financial crisis, private religious bodies have increasingly replaced public funding, raising important but still unaddressed moral questions about transparency, independence, and potential conflicts of interests. The present article explores the ethically troubling relationship between the boom of Big Data and computational approaches to the study of religions past and present and the infiltration of religious philanthrocapitalism in contemporary neoliberal academia.
Mechanism, Occasionalism and Final Causes in Johann Christoph Sturm’s Physics
Authors: Henkel Christian 
Published: November 2021

Abstract
This paper argues that mechanism, occasionalism and finality (the acceptance of final causes) can be and were de facto integrated into a coherent system of natural philosophy by Johann Christoph Sturm (1635–1703). Previous scholarship has left the relation between these three elements understudied. According to Sturm, mechanism, occasionalism and finality can count as explanatorily useful elements of natural philosophy, and they might go some way to dealing with the problem of living beings. Occasionalism, in particular, serves a unifying ground: It will be shown that occasionalism can account for the problems of the source and transmission of motion that mechanism faces, while at the same time explaining the finality of non-rational living beings as designed by God.
COVID-19, Business, and Human Rights
Authors: Deva Surya 
Published: November 2021

Abstract
COVID-19 has affected the full range of human rights, though some rights holders have experienced a disproportionate impact. This has triggered debate about the respective obligations and responsibilities of states and business enterprises under international human rights law. Against this backdrop, this article examines critically whether the “protect, respect and remedy” framework operationalised by the UN Guiding Principles on Business and Human Rights is “fit for the purpose” to deal with the COVID-19 crisis. I argue that while the UNGPs’ framework provides a good starting point, it is inadequate to bring transformative changes to overcome deep-rooted socio-economic problems exposed by this pandemic. Realising human rights fully would not only require harnessing the potential of states’ tripartite obligations, but also move beyond limiting the responsibility of businesses to respect human rights.
Tooth Position and Deformation of Flexspline Assembled with Cam in Harmonic Drive Based on Force Analysis

Published: November 2021

AbstractDeformation of the flexspline is the basis of analyzing tooth trajectory and designing tooth profile. Considering the tooth influence on the position of equivalent neutral layer, a piecewise method for calculating the deformation of flexspline assembled with a cam wave generator is presented in this paper. Firstly, a mechanic model of a ring of uniform thickness in contact with a rigid cam is established. The displacements of the ring inside and outside an unknown wrapping angle are determined by the geometric constraints of the cam profile and the equilibrium relationship, respectively. Meanwhile, the wrapping angle is solved according to the boundary conditions. The assembly forces are derived to investigate the circumferential elongation and strain. Then, considering the tooth effects on the neutral layer of flexspline, the tooth is positioned on the equivalent neutral layer, which is the non-elongation layer within one gear pitch but offset from the geometric mid-layer. The equivalent neutral layer is positioned by the empirical formula of the offset ratio, which is summarized by the orthogonal simulation on finite element models of racks. Finally, finite element models of a ring-shaped and a cup-shaped flexspline assembled with elliptical cam are established to verify the effectiveness and accuracy of the piecewise method. The results show that, compared with the geometric method, the tooth positioning deviation calculated by the piecewise method can be reduced by about 70% with a more accurate deformation description from the geometric condition and mechanic condition inside and outside the wrapping angle.
Raising the Speed Limit of Axial Piston Pumps by Optimizing the Suction Duct

Published: November 2021

AbstractThe maximum delivery pressure and the maximum rotational speed determine the power density of axial piston pumps. However, increasing the speed beyond the limit always accompanies cavitation, leading to the decrease of the volumetric efficiency. The pressure loss in the suction duct is considered a significant reason for the cavitation. Therefore, this paper proposes a methodology to optimize the shape of the suction duct aiming at reducing the intensity of cavitation and increasing the speed limit. At first, a computational fluid dynamics (CFD) model based on the full cavitation model (FCM) is developed to simulate the fluid field of the axial piston pump and a test rig is set to validate the model. Then the topology optimization is conducted for obtaining the minimum pressure loss in the suction duct. Comparing the original suction duct with the optimized one in the simulation model, the pressure loss in the suction duct gets considerable reduction, which eases the cavitation intensity a lot. The simulation results prove that the speed limit can increase under several different inlet pressures.
Risk factors for the frequent attendance of older patients at community health service centers in China: a cross-sectional study based on stratified sampling
Authors: Li Nana , Shou Juan 
Published: November 2021

Abstract
Background
This study aimed to investigate the characteristics of frequent attenders (FAs) among older patients in Shanghai, China, and explore the associated factors.

Methods
This cross-sectional study was conducted in six community health service centers in Shanghai, China, from August to December 2018 based on stratified sampling. On the basis of our preliminary study, FAs were defined as those attending at least four consultations in a month. A self-administered questionnaire was used to collect the clinicodemographic data of the participants. Social support, pain severity, depression, and anxiety were evaluated using the Social Support Revalued Scale, six-point Behavioral Rating Scale, Patient Health Questionnaire–9, and Generalized Anxiety Disorder Scale, respectively.

Results
This study included 619 patients aged > 60 years. Among these patients, 155 (25%) were FAs to a community health service center, 366 (59.1%) had 1 or 2 chronic diseases, 179 (28.9%) had ≥3 chronic diseases, 313 (50.4%) opted for a family doctor service, and 537 (86.8%) chose a community health service center for the first consultation. The following were identified as independent risk factors for frequent attendance: widowed status, unmarried status, the presence of > 3 chronic diseases, first consultation at a community health service center, high medical expenses, frequent attendance of the spouses, long-term medication, the use of both traditional Chinese and Western medicine services, and depression.

Conclusions
This study summarizes the characteristics of older FAs to community health service centers in China and identifies 10 risk factors significantly associated with frequent attendance.

Abstract
Background
Pylorus-preserving pancreatoduodenectomy (PPPD) with pancreatogastrostomy is a standard surgical procedure for pancreatic head tumors, duodenal tumors and distal cholangiocarcinomas. Post-operative pancreatic fistulas (POPF) are a major complication causing relevant morbidity and mortality. Endoscopic vacuum therapy (EVT) has become a widely used method for the treatment of intestinal perforations and leakages. Here we report on a pilot single center series of 8 POPF cases specifically caused by dehiscences of the pancreatogastric anastomosis (PGD), successfully managed by EVT.

Methods
We included all patients with PGD after PPPD, who were treated with EVT between 07/2017 and 08/2020. For EVT a vacuum drainage film (EVT film) or open-pore polyurethane foam sponge (EVT sponge) was fixed to a 14Fr or 16Fr suction catheter and placed endoscopically within the PGD for intracavitary EVT with continuous suction between − 100 and − 150 mmHg. The EVT film/sponge was exchanged twice per week. EVT was discontinued when the PGD was sufficiently healed.

Results
PGD closure was achieved in 7 of 8 patients after a mean EVT time of 16 days (range 8–38) and 3 EVT film/sponge exchanges (range 1–9). One patient died on day 18 after PPPD from acute hemorrhagic shock, unlikely related to EVT, before effectiveness of EVT could be fully achieved. There were no adverse events directly attributable to EVT.

Conclusions
EVT could be an effective and safe addition to our therapeutic armamentarium in the management of POPF with PGD. Unless prospective comparative studies are available, EVT as minimally invasive therapeutic alternative should be considered individually by an interdisciplinary team involving endoscopists, surgeons and radiologists.

Authors: Wang Chun-Chieh , Chen Yu-Yen , Hung Kuo-Chuan , Wu Shang-Jung , Yen Yung-Feng , Chen Chu-Chieh , Lai Yun-Ju 
Published: November 2021

Abstract
Background
To examine the association between teeth loss and nasogastric tube feeding dependency in older people.

Methods
The National Health Interview Survey (NHIS) 2005, 2009, and 2013 in Taiwan. Participants were selected by a multistage stratified sampling method and baseline characteristics, including socioeconomic status and health habits, were obtained by well-trained interviewers. The NHIS was linked with the National Health Insurance research database 2000–2016 and the National Deaths Dataset, which contains all the medical information of ambulatory and inpatient care. Cox regression was used to examine the association between the number of teeth lost and nasogastric tube feeding dependency.

Results
There were 6165 adults older than 65 years old enrolled in the analysis, with 2959 male (48%) and the mean (SD) age was 73.95(6.46) years old. The mean follow-up duration was 6.5(3.3) years. Regarding the teeth loss categories, 1660 (26.93%), 2123 (34.44%), and 2382 (38.64%) of participants were categorized as having no teeth loss, loss of 1–9 teeth, and loss of 10–28 teeth, respectively. During 39,962 person-years of follow-up, new-onset nasogastric feeding dependency was recognized in 220(13.25%), 256(12.06%), and 461(19.35%) participants who were categorized as having no teeth loss, loss of 1–9 teeth, and loss of 10–28 teeth, respectively. Kaplan-Meier curves demonstrated significant findings (Log-rank P < 0.01). After potential confounders were adjusted, compared with those without teeth loss, older adults who had lost 10–28 teeth had significantly increased risks of occurrence nasogastric feeding dependency (AHR, 1.31; 95% CI, 1.05–1.62; p-value = 0.02). Furthermore, a significant dose-response relation between the number of teeth lost and increased risk of nasogastric feeding was found (p for trend< 0.01).

Conclusions
Older adults who had lost 10–28 teeth had a significantly increased risk of nasogastric tube feeding dependency. Early identification of the oral disease is crucial for the prevention of the occurrence of teeth loss and the following nutrition problems, which would reduce risk of nasogastric tube feeding dependency.

Published: November 2021

Abstract
Background
Up to 50% of women in areas of high socio-economic deprivation are at risk of developing depressive symptoms in pregnancy. Feeling well supported, can facilitate good mental health perinatally. A brief, innovative intervention to facilitate access to support and resources was developed and tested. This included one antenatal and one postnatal session, each with three evidence-based components: i) support from a non-professional peer to enable a woman to identify her needs; ii) information about local community services and signposting; and iii) development of a personalised If–Then plan to access that support. The aims were to evaluate the intervention and research methods for feasibility and acceptability for perinatal women, maternity care providers and peers, and provide preliminary effectiveness indications.

Methods
Pregnant women living in an area of high deprivation were recruited from community-based antenatal clinics and randomised to intervention or control condition (a booklet about local resources). Outcome measures included women’s use of community services by 34 + weeks gestation and 6 months postnatally; mental health and wellbeing measures, and plan implementation. Interviews and focus groups were conducted with women participants, providers, and peers. Data were analysed using framework analysis. Recruitment and retention of peers and participants, intervention fidelity, and acceptability of outcome measures were recorded.

Results
Peer facilitators could be recruited, trained, retained and provide the intervention with fidelity. One hundred twenty six women were recruited and randomised, 85% lived in the 1% most deprived UK areas. Recruitment constituted 39% of those eligible, improving to 54% after midwifery liaison. Sixty five percent were retained at 6 months postnatally. Women welcomed the intervention, and found it helpful to plan access to community services. Providers strongly supported the intervention philosophy and integrated this easily into services. The study was not powered to detect significant group differences but there were positive trends in community service use, particularly postnatally. No differences were evident in mental health and wellbeing.

Conclusions
This intervention was well received and easily integrated into existing services. Women living in highly deprived areas could be recruited, randomised and retained. Measures were acceptable. Peer facilitators were successfully trained and retained. Full effectiveness studies are warranted.
