Identifying Trends of Dysautonomia Signs and Symptoms Associated with Protracted Concussion Recovery during the Buffalo Concussion Treadmill Test: A Retrospective Study
Authors: Ziaks Lauren , Tucker Jenna , Koc Thomas , Schaefer Alexa , Hanson Kristina 
Published: March 2022

Abstract

Objective:
To identify trends of provoked dysautonomia signs and symptoms during the Buffalo Concussion Treadmill Test (BCTT).

Subjects:
This is a retrospective cohort study of 101 patient charts post-concussion who were screened for suspected dysautonomia.

Methods:
Patients with suspected dysautonomia were assessed for exercise intolerance using a BCTT. Symptoms and rate of perceived exertion were recorded on a standardized form. Digital pulse oximetry was used to collect heart rate (HR) and oxygen saturation. Descriptive analyses were conducted on BCTT results.

Results:
Of 101 patient charts, 57 were excluded from analysis, including four patients who completed the BCTT by asymptomatically reaching the target HR zone for their estimated HR max. The remaining 44 patients demonstrated: 35 (79.5%) poor HR stabilization defined as a drop or plateau in HR during exercise, 28 (63.8%) exacerbated concussion symptoms, 13 (29.5%) autonomic nervous system response such as hot flushed sensation, 12 (27.3%) rebound symptoms during recovery phases, and 8 (18.2%) desaturation of 90% or below. The mean delta (80% expected HR max – 80% achieved HR max) on the initial test was 80.66 (± 23.08) beats per minute.

Conclusions:
This study is the first to identify trends of signs and symptoms during the BCTT in an expanded population with suspected dysautonomia after concussion. Future studies are indicated to validate these findings and contribute to development of modified termination criteria for the BCTT in individuals with suspected dysautonomia associated with protracted concussion recovery.
Empty Space, Silence, and Absence
Authors: Gow Laura 
Published: March 2022

AbstractThe idea that we can perceive absences is becoming increasingly popular in contemporary philosophy of mind, and seeing empty space and hearing silence are alleged to be two paradigmatic examples. In this paper, I remain neutral over the question of whether empty space experiences and experiences of silence are genuinely perceptual phenomena, however, I argue that these experiences do not qualify as absence experiences. Consequently, our experiences of empty space and silence cannot be appealed to as proof of the perceptual view of absence experience.
Principal component density estimation for scenario generation using normalizing flows
Authors: Cramer Eike , Mitsos Alexander , Tempone Raúl , Dahmen Manuel 
Published: March 2022

Abstract
Neural networks-based learning of the distribution of non-dispatchable renewable electricity generation from sources, such as photovoltaics (PV) and wind as well as load demands, has recently gained attention. Normalizing flow density models are particularly well suited for this task due to the training through direct log-likelihood maximization. However, research from the field of image generation has shown that standard normalizing flows can only learn smeared-out versions of manifold distributions. Previous works on normalizing flow-based scenario generation do not address this issue, and the smeared-out distributions result in the sampling of noisy time series. In this paper, we exploit the isometry of the principal component analysis (PCA), which sets up the normalizing flow in a lower-dimensional space while maintaining the direct and computationally efficient likelihood maximization. We train the resulting principal component flow (PCF) on data of PV and wind power generation as well as load demand in Germany in the years 2013–2015. The results of this investigation show that the PCF preserves critical features of the original distributions, such as the probability density and frequency behavior of the time series. The application of the PCF is, however, not limited to renewable power generation but rather extends to any dataset, time series, or otherwise, which can be efficiently reduced using PCA.

Abstract

Objectives:
During the coronavirus disease (COVID-19) pandemic, health care workers, including nurses and their family members, experienced various psychological problems. Coping skills may help them deal with the current challenge and maintain their mental health and improve their quality of life. Therefore, this study investigated the relation of coping skills with mental health and quality of life of the nurses’ family members during the COVID-19 pandemic.

Methods:
This cross-sectional study was conducted on the family members of the nurses working at Hajar Hospital of Shahrekord dedicated to admission and hospitalization of COVID-19 infected patients using a census sampling method in 2020. Participation in this study was voluntary and finally 220 persons were included in this study. To prevent the spread of COVID-19 through respiratory droplets or contact, a weblog was created using blogging software that contained questionnaires for collecting data on demographic information, mental health (PHQ-9), coping skills (coping responses inventory [CRI], Billings & Moos), and quality of life (SF-36). The collected data were analyzed using descriptive and inferential statistical tests in SPSS software version 22 (IBM Corp, Armonk, NY).

Results:
Of the 220 participants in this study, 101 participants were male and 119 were female. The mean age of the subjects was 35.78 years, and 56.4% of them had an academic education level. The Pearson correlation analysis showed a significant relationship between coping skills and mental health, quality-of-life items, total quality-of-life score, and demographic variables of participants (except education) (P < 0.05). This was a direct relationship in such a way that as the score of coping skills increases, so does the score of mental health and quality of life. Based on the results of regression analysis, the predictive power of mental health, coping skills, and education level was obtained to be 0.634. The coping skill variable was the strongest predictor (ß = 0.467), and after that, the mental health variable (ß = 0.421) had the highest predictive power.

Conclusion:
The obtained results showed that coping skill is the association between psychological health and quality of life such that the coping skill has a significant direct effect on psychological health and quality of life. The results also showed that, at the time of crisis, further attention should be paid to coping skills to develop and improve the quality of life and psychological health.
Foedus and testamentum: Calvin's federal terminology in Hebrew 8–10
Authors: Brewer J. Brittain 
Published: March 2022

AbstractCalvin's significance in the development of federal theology has received much attention. Scholars have often neglected, however, the role that his exegesis played in his own construal of covenant ideas. More specifically, Calvin's reading of covenant in the book of Hebrews has played a negligible part in reconstructing Calvin's broader understanding of covenant. By looking closely at Calvin's exegesis and the terminological diversity in his commentaries on Hebrews 8–10, a more complex picture emerges. The federal terminology employed in these sections of his commentaries evidences exegetical sensitivity and doctrinal complexity. Calvin not only stands in the stream of Reformed covenant doctrine, but his exegesis represents an early instinct that noticed the tension at work in passages like Hebrews 8–10.
What difference does one's view of God make in understanding sin and salvation? Some suggestions from Karl Barth
Authors: Molnar Paul D. 
Published: March 2022

AbstractThis article argues that views of sin and salvation are shaped by one's view of God. Thus, whenever it is thought that God is a metaphor that theologians can change to attain a desired social or psychological result, then the true meaning of sin and salvation are lost. Relying on Karl Barth's view of Jesus as the Judge judged in our place, this article argues against ideas that sin can no longer be understood as self-will, and that salvation must be understood only as our working for a better world. Such views fail to recognise that, since only God can reveal God, the true meaning of sin is and remains most visible today in our attempts to redefine God and salvation in social and psychological rather than strictly theological terms.
When do municipalities smooth access for new social assistance claimants? Local determinants of municipal welfare agency’s implementation practices in Belgium
Authors: JANSSENS JULIE , MARCHAL SARAH 
Published: March 2022

AbstractIn many Western countries local welfare agencies retain large responsibilities in the practical organisation of means-tested support. While this may lead to substantial differences in the application trajectories of prospective claimants, what has garnered little empirical research is how local agencies use their discretion to implement practices that may encourage or discourage take-up. In addition, we know little on the extent to which variation in local implementation is attributable to differences in local conditions. Focusing on Belgium as an interesting case, this article addresses this gap by mapping the variation in local implementation practices in specific aspects of social assistance that are relevant in terms of limiting non-take-up. We assess whether certain local political, socio-demographic or economic characteristics favour implementation practices, using structural equation modelling on custom-collected data on the practical organisation of social assistance application trajectories in 119 Belgian municipalities. The results show that local welfare agencies implement coherent practices regarding information provision, accessibility, trust and the locus of initiative in the claiming process. We find the political orientation of the municipality and the share of foreigners in the municipality to be related with, respectively, shifting the locus of initiative away from the welfare claimant and a focus on information provision.
Institutional Business Power: The Case of Ireland’s Private Home Care Providers
Authors: MERCILLE JULIEN , O’NEILL NICHOLAS 
Published: March 2022

AbstractThe marketisation of European home care has given rise to significant private for-profit providers growth. However, little research has focused directly on commercial companies to examine the mechanisms through which they emerge, grow and shape long-term care policy – this is this paper’s task. Drawing on the literature on business power, the recent concept of “institutional business power” is introduced, defined as the power flowing from the entrenched position of business actors in the provision of public social services. The paper identifies the mechanisms through which private providers have grown and assesses the extent of their institutional power by examining their influence on policy and the support they obtain from relevant home care stakeholders. The limits of providers’ institutional power are also discussed. The paper relies on semi-structured interviews with representatives of public, private and non-profit home care providers.
Response of avian and mammal seed dispersal networks to human-induced forest edges in a sub-humid tropical forest
Authors: Chaves Patrícia P. , Timóteo Sérgio , Gomes Sara , Rainho Ana 
Published: March 2022

AbstractSpecies-rich ecosystems as tropical forests are extremely vulnerable to anthropogenic destruction. Most tropical plant species rely on animals to disperse their seeds. However, patterns of mutualistic interactions have rarely been explored, and seed dispersal networks are still poorly studied in Africa. Here, we examine how forest edges’ (FE) seed dispersal networks differ from the mature forest (MF) at a West African sub-humid tropical forest within the National Park of Cantanhez (Guinea-Bissau). Additionally, we explore species’ roles within the network. MF had higher fruit availability, more frugivore visitors, and plant–frugivore interactions. Network structure was quite similar between habitats, showing signs of redundancy, and some robustness to species’ extinction. FE was more nested, modular, and specialized, whereas MF had higher connectance, interaction evenness, and robustness to extinction. Most species were generalists, but large-bodied frugivores prevailed at MF. FE showed a higher vulnerability, mostly to the loss of trees. Trees are key, keeping the structure of both networks. Large-bodied frugivores and fruiting-tree species that work as network connectors should thus be the focus of active conservation management in these forests. Only viable populations of these species will ensure a good performance of the seed dispersal network, promoting the natural regeneration of the ecosystem.
Cities, infrastructure and the making of modern citizenship: the view from north-west Europe since c. 1870
Authors: Gunn Simon , Butler Richard , De Block Greet , Høghøj Mikkel , Thelle Mikkel 
Published: March 2022

AbstractTaking its cue from the ‘material turn’ of recent years, this survey examines the connections between infrastructure, welfare and citizenship in north European cities in the later nineteenth and twentieth centuries. It argues that connections between these different constructs were fundamental not only to how cities functioned but how citizens themselves were imagined. As such, the survey critiques histories of welfare and citizenship that foreground the national and neglect the urban origins of the modern state. It does so by examining infrastructure, welfare and citizenship in smaller European nation-states such as Belgium, Denmark and Ireland rather than in the more familiar cases of Germany, France and Britain. Asking questions about the inter-relationship of infrastructure, welfare and citizenship, the survey suggests, offers an important way to reinterpret what the ‘modern city’ meant in twentieth-century northern Europe.

AbstractObjective:The aim of the study was to evaluate the early myocardial dysfunction detected by strain echocardiography in children with multisystem inflammatory syndrome related to SARS-CoV-2 infection.Methods:This cross-sectional study was conducted with 47 patients diagnosed with MIS-C and 32 healthy age- and gender-matched children. All patients underwent two-dimensional, colour, pulsed, and tissue Doppler, and 2D speckle tracking echocardiography examination at admission, 2 weeks, and 2 months after discharge. The MIS-C patient group was compared with the control group. Echocardiographic changes in MIS-C patients during follow-up were evaluated.Results:Of 47 patients, 30 (63.8%) were male and 17 (36.2%) were female. The mean age at diagnosis was 9.1 ± 4.3 (1.25–17) years. At admission, 25 patients had abnormal findings on conventional echocardiography. Among them, eight patients had left ventricular systolic dysfunction. Ejection fraction and fractional shortening were significantly lower in the patient group at admission compared to controls (p = 0.013, p = 0.010, respectively). While the ejection fraction was <55% in eight patients, and global longitudinal strain was lower than −2SD in 29 patients at admission. Global longitudinal strain z-score <−2SD persisted in 13 patients at 2-month follow-up. Ejection fraction increased above 55% in 3.42 ± 0.53 days in 7 of 8 patients with left ventricular systolic dysfunction, ejection fraction was 51% at discharge in one patient, and left ventricular systolic dysfunction persisted at the 6-month of follow-up.Conclusion:These results confirmed that speckle tracking echocardiography is more likely to detect subclinical myocardial damage compared to conventional echocardiography. In addition, it is a valuable method for follow-up in this patient group.
A rare prenatal diagnosis: congenital absence of aortic valve
Authors: Ayyildiz Pelin , Aydemir Merve M. , Guzeltas Alper 
Published: March 2022

AbstractCongenital absence of the aortic valve is characterised by the absence of aortic valve and severe regurgitation. The rest of the reported cases were mostly diagnosed either on postnatal echocardiography or autopsy. Here, we present a foetal case with the absence of the aortic valve and “inverse circulatory shunt”.
Low-Z FIB Grids for Reducing Spurious Fluorescence and X-ray Overlaps

Published: March 2022

Abstract:Low-Z nanocrystalline diamond (NCD) grids have been developed to reduce spurious fluorescence and avoid X-ray peak overlaps or interferences between the specimen and conventional metal grids. The low-Z NCD grids are non-toxic and safe to handle, conductive, can be subjected to high-temperature heating experiments, and may be used for analytical work in lieu of metal grids. Both a half-grid geometry, which can be used for any lift-out method, or a full-grid geometry that can be used for ex situ lift-out or thin film analyses, can be fabricated and used for experiments.
Bayesian Framework for Inversion of Second‐Order Stress Glut Moments: Application to the 2019 Ridgecrest Sequence Mainshock
Authors: Atterholt James , Ross Zachary E. 
Published: March 2022

AbstractWe present a fully Bayesian inverse scheme to determine second moments of the stress glut using teleseismic earthquake seismograms. The second moments form a low‐dimensional, physically motivated representation of the rupture process that captures its spatial extent, source duration, and directivity effects. We determine an ensemble of second‐moment solutions by employing Hamiltonian Monte Carlo and automatic differentiation to efficiently approximate the posterior. This method explicitly constrains the parameter space to be symmetric positive definite, ensuring the derived source properties have physically meaningful values. The framework accounts for the autocorrelation structure of the errors and incorporates hyperpriors on the uncertainty. We validate this methodology using a synthetic test and subsequently apply it to the 2019 Mw7.1 Ridgecrest earthquake using teleseismic data. The distributions of second moments determined for this event provide probabilistic descriptions of low‐dimensional rupture characteristics that are generally consistent with results from previous studies. The success of this case study suggests that probabilistic and comparable finite source properties may be discerned for large global events regardless of the quality and coverage of local instrumentation.
Investigating Tropical Versus Extratropical Influences on the Southern Hemisphere Tropical Edge in the Unified Model

Published: March 2022

AbstractSince the late 1970s, observations have shown a widening of the tropical Hadley cell (HC) circulation. State‐of‐the‐art climate models reproduce the general trend along with a projected continuous expansion. Discrepancies in expansion rates of observation‐ and model‐based studies have been attributed to differences in applied methods, natural variability and model shortcomings. Furthermore, the driving influence of tropical or extratropical processes on these changes is not well understood. All of this highlights the dynamical mechanisms and the region of origin controlling the tropical width are still insufficiently understood. Here we examine the influence of systematic model biases of the atmosphere‐only Unified Model (UM) onto the simulation of the Southern Hemisphere (SH) tropical edge. We utilize nudged experiments with prescribed sea surface temperatures, where potential temperature and horizontal winds are relaxed back to ERA‐Interim reanalysis for a 20‐year period in selected regions. Correcting model biases in the tropics and extratropics separately allows us to dissect the dominant remote impacts of present model errors onto the SH tropical edge simulation. The experiments are applied to established tropical width metrics ranging from near‐surface to upper‐level metrics capturing the poleward flank of the HC. We find both regions work remotely to reduce errors in the UM fields and location of the tropical edge. Surprisingly, correcting the extratropical biases, south of 45°S, more consistently improves the tropical width across the metrics and seasons than nudging the tropics (10°N–10°S). These findings demonstrate the substantial role of extratropical influences in locating the SH tropical edge.
Leak Localization in Looped Pipe Networks Based on a Factorized Transient Wave Model: Theoretical Framework
Authors: Che Tong‐Chuan , Wang Xun , Ghidaoui Mohamed S. 
Published: March 2022

AbstractUrban water distribution systems are often made of loops to increase redundancy and improve reliability. The inherent feature of multipath wave propagation in looped networks has been the main obstacle to directly derive a factorized wave propagation model with decoupled leak location and size, which is essential for developing a robust and efficient leak localization method. To address this problem, this article proposes an efficient algorithm to estimate the transient hydraulic pressure and discharge at all nodes of a looped network using boundary measurements. Given these hydraulic properties, a factorized wave propagation model is formulated by applying conservation laws to a tree‐shaped control volume of the looped network. Based on this factorized model, a fast and efficient one‐dimensional search of the leak location along all pipes of a looped network is realized by the matched‐field processing technique. Numerical experiments demonstrate that an unknown leak anywhere in a five‐loop network with 13 pipes can be accurately and efficiently localized by the proposed method.
Subsidence in Coastal Cities Throughout the World Observed by InSAR
Authors: Wu Pei‐Chin , Wei Meng (Matt) , D’Hondt Steven 
Published: March 2022

AbstractWe measured subsidence rates in 99 coastal cities around the world between 2015 and 2020 using the PS Interferometric Synthetic Aperture Radar method and Sentinel‐1 data. In most cities, part of the land is subsiding faster than sea level is rising. If subsidence continues at present rates, these cities will be challenged by flooding much sooner than projected by sea level rise models. The most rapid subsidence is occurring in South, Southeast, and East Asia. However, rapid subsidence is also happening in North America, Europe, Africa, and Australia. Human activity—primarily groundwater extraction—is likely the main cause of this subsidence. Expanded monitoring and policy interventions are required to reduce subsidence rates and minimize their consequences.
