AbstractClimatically extreme regions such as the polar deserts of the McMurdo Dry Valleys (78° S) in Continental Antarctica are key areas for a better understanding of changes in ecosystems. Therefore, it is particularly important to analyze and communicate current patterns of biodiversity in these sensitive areas, where precipitation mostly occurs in form of snow and liquid water is rare. Humidity provided by dew, clouds, and fog are the main water sources, especially for rock-dwelling crustose lichens as one of the most common vegetation-forming organisms. We investigated the diversity and interaction specificity of myco-/photobiont associations of 232 crustose lichen specimens, collected along an elevational gradient (171–959 m a.s.l.) within the McMurdo Dry Valleys. The mycobiont species and photobiont OTUs were identified by using three markers each (nrITS, mtSSU, RPB1, and nrITS, psbJ-L, COX2). Elevation, positively associated with water availability, turned out to be the key factor explaining most of the distribution patterns of the mycobionts. Pairwise comparisons showed Lecidea cancriformis and Rhizoplaca macleanii to be significantly more common at higher elevations and Carbonea vorticosa and Lecidea polypycnidophora at lower elevations. Lichen photobionts were dominated by the globally distributed Trebouxia OTU, Tr_A02 which occurred at all habitats. Network specialization resulting from myco-/photobiont bipartite network structure varied with elevation and associated abiotic factors. Along an elevational gradient, the spatial distribution, diversity, and genetic variability of the lichen symbionts appear to be mainly influenced by improved water relations at higher altitudes.

Published: October 2020

AbstractClinical psychology intervention in paediatric gastroenterology is vital given the biopsychosocial aetiology of paediatric functional gastrointestinal disorders, and the psychological impact of chronic conditions. The aim was to assess the availability and benefit of clinical psychology in paediatric gastroenterology across the UK and Germany. A retrospective assessment of referrals (n = 936 referrals) to clinical psychology was performed at our tertiary paediatric gastroenterology centre between 2010 and 2018. The availability of clinical psychologists and outcome of psychology intervention for children with functional abdominal pain were also assessed. Access to clinical psychology across the UK and Germany was assessed using an online questionnaire. We observed a substantial rise in the number of clinical psychology referrals between 2010 and 2018. Increasing demand was not matched by sufficient increase in availability of clinical psychology, leading to longer waiting times. A major benefit of clinical psychology intervention was highlighted with 95% of patients (n = 20) reporting a significant reduction in symptoms. Of the 12 centres who responded, 11 centres have direct access to clinical psychology with a mean of 13% of patients requiring psychology referrals annually.Conclusion: Despite evidence of its benefit and increasing demand, there is insufficient access to clinical psychological services, highlighting the urgent need to address this important issue.

What is known:• The biopsychosocial pathophysiology of functional gastrointestinal disorders involves a disordered brain-gut interaction, which emphasizes the close link between psychological factors and altered gut function.• Psychological intervention, as an adjunct to medical treatment, improves outcomes in paediatric patients with gastrointestinal (GI) disease such as functional gastrointestinal disorders and inflammatory bowel diseasesWhat is new:• There is a rising number of referrals from paediatric gastroenterology to clinical psychology in our centre which is not met by a sufficient increase in the availability of clinical psychologists. Similarly, access to clinical psychological services is lacking in several paediatric gastroenterology centres in the UK and Germany.• Strategic action is required to address this important gap in the care of children suffering from GI diseases.

AbstractKey messageSome species synthesize larger amounts of polyprenols, which probably increase the plant’s ability to mitigate salt stress. Salt stress does not cause macronutrient deficiency in the leaves of urban trees. Ionic imbalance in the leaves caused by soil salinity worsens the health status of sensitive species.AbstractStreet trees are exposed to relatively high stress levels, and the average lifespan of street trees is shortened compared to those of trees living under controlled natural conditions. Soil salinity adversely affects trees at all stages of growth and development. This study attempts to determine how the urban environment, with particular emphasis on salt stress, affects tree species with different levels of salinity sensitivity. The aim of this study was to identify the strategies of eight tree species for mitigating salt stress based on the determination of the chemical composition of the macroelements in the leaves, the ionic imbalance, and the ability of the trees to synthesize and accumulate polyprenols in the leaves. The obtained results suggest that individual species implemented different strategies in response to salt stress. The low sensitivity species:Q. rubra, R. pseudoacacia, G. triacanthosandA. campestre. blocked the uptake of Cl and Na to the leaves. The medium-sensitivity species:P. x hispanicablocked the uptake of Cl and Na andG. bilobamaintained very high contents of Cl and Na in its leaves without leaf damage and synthesized large amounts of polyprenols.G. triacanthos and A. campestresynthesized large amounts of polyprenols. The high-sensitivity species (T. x euchloraandA. platanoides) exhibited very high contents of Cl and Na in their leaves, which were significantly damaged and had a pronounced ionic imbalance. These effects were not compensated for by the increased synthesis of polyprenols. In conclusion, the accumulation of polyprenols in leaf tissue may be one of the strategies that increase the resistance of plants to salt stress. Plants have many other methods of mitigating salt stress.

Abstract
Aims
People with type 1 diabetes (T1D) face the daily task of implementing self-management strategies to achieve their glycaemic goals. The UK COVID-19 lockdown has had an impact on day-to-day behaviour, which may affect diabetes self-management and outcomes. We assessed whether sensor-based outcomes pre- and during lockdown periods were different in a cohort of glucose sensor users with T1D.

Methods
Data were collected from Freestyle Libre (FSL) or Dexcom G6 sensor users who remotely shared their data with the diabetes clinic web platform. Sensor metrics according to international consensus were analysed and compared between pre-lockdown period and 2 and 3 weeks into lockdown (periods 1 and 2).

Results
Two hundred and sixty-nine T1D patients (baseline HbA1c 57 ± 14 mmol/mol) were identified as FSL (n = 190) or Dexcom G6 (n = 79) users. In patients with sensor use > 70% (N = 223), compared to pre-lockdown period percentage TIR 3.9–10 mM (TIR) significantly increased during period 1 (59.6 ± 18.2 vs. 57.5 ± 17.2%, p = 0.002) and period 2 (59.3 ± 18.3 vs. 57.5 ± 17.2%, p = 0.035). The proportion of patients achieving TIR ≥ 70% increased from 23.3% pre-lockdown to 27.8% in period 1 and 30.5% in period 2. A higher proportion also achieved the recommended time below and above range, and coefficient of variation in periods 1 and 2. Dexcom G6 users had significantly lower % time below range (< 3.9 mM) compared to FSL users during both lockdown periods (period 1: Dexcom G6 vs. FSL: 1.8% vs. 4%; period 2: 1.4% vs. 4%, p < 0.005 for both periods).

Conclusion
Sensor-based glycaemic outcomes in people with T1D in the current cohort improved during COVID-19 lockdown, which may be associated with positive changes in self-management strategies. Further work is required to evaluate long-term sustainability and support.
Posterior transdural resection of giant calcified thoracic disc herniation in a case series of 12 patients

Published: October 2020

AbstractCalcified thoracic disc herniations present a rare and challenging entity. Due to the close proximity to the spinal cord and relative narrowing of the spinal canal, the optimal approach remains a matter of debate. While the transthoracic approach is usually preferred, we adapted a new technique described in 2012: the transdural posterior approach. Our aim was to evaluate its benefits in patients with giant thoracic disc protrusions. We retrospectively reviewed all patients treated in our neurosurgical department from July 2012 to March 2020. Demographics, pre- and postoperative clinical status, and operative technique and complications were extracted and analyzed. In total, 12 patients underwent a posterior transdural resection of giant calcified thoracic hard discs between 2012 and 2020. All patients underwent a posterior decompression (laminectomy, hemilaminectomy, or laminoplasty). The median duration of surgery was 152 min. Transient postoperative neurological deterioration occurred in 4 patients, with complete recovery until time of discharge. No patient underwent a surgical revision. The transdural resection of giant calcified thoracic hard discs through a posterior approach provides an excellent decompression with sufficient visualization of the spinal cord and a satisfying postoperative outcome.
Towards enabling a cardiovascular digital twin for human systemic circulation using inverse analysis
Authors: Chakshu Neeraj Kavan , Sazonov Igor , Nithiarasu Perumal 
Published: October 2020

AbstractAn exponential rise in patient data provides an excellent opportunity to improve the existing health care infrastructure. In the present work, a method to enable cardiovascular digital twin is proposed using inverse analysis. Conventionally, accurate analytical solutions for inverse analysis in linear problems have been proposed and used. However, these methods fail or are not efficient for nonlinear systems, such as blood flow in the cardiovascular system (systemic circulation) that involves high degree of nonlinearity. To address this, a methodology for inverse analysis using recurrent neural network for the cardiovascular system is proposed in this work, using a virtual patient database. Blood pressure waveforms in various vessels of the body are inversely calculated with the help of long short-term memory (LSTM) cells by inputting pressure waveforms from three non-invasively accessible blood vessels (carotid, femoral and brachial arteries). The inverse analysis system built this way is applied to the detection of abdominal aortic aneurysm (AAA) and its severity using neural networks.
Scalp Topography of Lower Urinary Tract Sensory Evoked Potentials

Published: October 2020

AbstractImpaired lower urinary tract (LUT) afferents often cause LUT symptoms. Assessment of LUT afferent pathways is possible using bipolar cortical sensory evoked potential (SEP) recordings with the active electrode at the vertex during electrical stimulation in the LUT. This study aimed to investigate the topographical distribution and microstates of lower urinary tract sensory evoked potentials (LUTSEPs) using different stimulation frequencies. Ninety healthy subjects (18–36 years old, 40 women) were randomly assigned to one of five stimulation locations [bladder dome; trigone; proximal, membranous (men only) or distal urethra]. Cycles of 0.5 Hz/1.1 Hz/1.6 Hz electrical stimulation were applied using a custom-made catheter. Cortical activity was recorded from 64 surface electrodes. Marker setting was performed manually on an individual subject-level for the P1, N1, and P2 components of vertex recordings. N1 and P2 topographies presented with central negativities and positivities around the vertex. Regarding topographical distribution, Randomization Graphical User interface (RAGU) analyses revealed consistent frequency effects and microstates for N1/P2. Higher stimulation frequencies resulted in decreasing map strength for P1, N1, and P2. LUTSEP topographies suggest central generators in the somatosensory cortex, which are not detectable in a bipolar set-up. The observed frequency effect indicates fiber refractoriness at higher frequencies. The multichannel approach allows more comprehensive assessment of LUTSEPs and might therefore be sensitive to pathological changes. Examinations in patients with LUT symptoms are needed to further investigate this biomarker.
MEmoFC: introducing the Multilingual Emotional Football Corpus

Published: October 2020

AbstractThis paper introduces a new corpus of paired football match reports, the Multilingual Emotional Football Corpus, (MEmoFC), which has been manually collected from English, German, and Dutch websites of individual football clubs to investigate the way different emotional states (e.g. happiness for winning and disappointment for losing) are realized in written language. In addition to the reports, it also contains the statistics for the selected matches. MEmoFC is a corpus consisting of comparable subcorpora since the authors of the texts report on the same event from two different perspectives—the winner’s and the loser’s side, and from an arguably more neutral perspective in tied matches. We demonstrate how the corpus can be used to investigate the influence of affect on the reports through different approaches and illustrate how game outcome influences (1) references to the own team and the opponent, and (2) the use of positive and negative emotion terms in the different languages. The MEmoFC corpus, together with the analyzed aspects of emotional language will open up new approaches for targeted automatic generation of texts.

AbstractEconomic and ecological systems are closely interlinked at a global and a regional level, offering a broad variety of important research topics in environmental and resource economics. The successful identification of key challenges for current and future research supports development of novel theories, empirical applications, and appropriate policy designs. It allows establishing a future-oriented research agenda whose ultimate goal is an efficient, equitable, and sustainable use of natural resources. Based on a normative foundation, the paper aims to identify fundamental topics, current trends, and major research gaps to motivate further development of academic work in the field.
General methods and properties to evaluate continuum limits of the 1D discrete time quantum walk
Authors: Manighalam Michael , Kon Mark 
Published: October 2020

AbstractModels of quantum walks which admit continuous time and continuous spacetime limits have recently led to quantum simulation schemes for simulating fermions in relativistic and nonrelativistic regimes (Molfetta GD, Arrighi P. A quantum walk with both a continuous-time and a continuous-spacetime limit, 2019). This work continues the study of relationships between discrete time quantum walks (DTQW) and their ostensive continuum counterparts by developing a more general framework than was done in Molfetta and Arrighi (A quantum walk with both a continuous-time and a continuous-spacetime limit, 2019) to evaluate the continuous time limit of these discrete quantum systems. Under this framework, we prove two constructive theorems concerning which internal discrete transitions (“coins”) admit nontrivial continuum limits. We additionally prove that the continuous space limit of the continuous time limit of the DTQW can only yield massless states which obey the Dirac equation. Finally, we demonstrate that for general coins the continuous time limit of the DTQW can be identified with the canonical continuous time quantum walk when the coin is allowed to transition through the continuous limit process.
A Thematic Analysis of Sports Bettors’ Perceptions of Sports Betting Marketing Strategies in the UK
Authors: Killick Elizabeth A. , Griffiths Mark D. 
Published: October 2020

AbstractIn the UK and other countries in the world, the volume of gambling advertisements is increasing, as is the popularity of online sports betting. While there is increasing research examining the content of such advertising, there is little research examining what gamblers themselves think about such advertising. Consequently, the aim of the present study was to firstly, explore the attitudes and opinions of sports bettors in response to marketing techniques used by the gambling industry and secondly, explore the perceived impact advertising has on their sports betting behavior. Semi-structured interviews were conducted with a sample of 19 UK sports bettors aged between 21 and 32 years old. Thematic analysis (TA) was used to analyze the transcripts. The analysis identified three main themes: (i) “temptation to gamble,” (ii) “promotion characteristics of gambling,” and (iii) “regulating gambling advertising.” Each theme consisted of two or three subthemes that illustrated the underlying factors that were perceived to be important aspects that contributed to the opinions and attitudes towards the advertising. Findings indicate that specific inducements including enhanced odds and “request-a-bet” promotions were perceived to increase feelings of control and reduce feelings of risk, in some cases resulting in the placing of impulsive bets. According to the participants, social media marketing was found to be intrusive and the frequency of gambling advertising contributed to the normalization of betting. The present study highlights the need for further research into the efficacy of current advertising regulations in the UK, with the end goal of minimizing gambling-related harm.

AbstractPurposePersistent fatigue among colorectal cancer (CRC) patients might be associated with unfavorable body composition, but data are sparse and inconsistent. We studied how skeletal muscle index (SMI), skeletal muscle radiodensity (SMR), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) at diagnosis are associated with fatigue up to 24 months post-diagnosis in stage I–III CRC patients.MethodsSMI, SMR, VAT, and SAT were assessed among 646 CRC patients using pre-treatment computed tomography images. Fatigue at diagnosis, at 6, and 24 months post-diagnosis was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. The association of SMI, SMR, VAT, and SAT with fatigue (yes/no) was assessed using confounder-adjusted restricted cubic spline analyses.ResultsPrevalence of fatigue at diagnosis was 18%, at 6 months 25%, and at 24 months 12%. At diagnosis, a significant (p = 0.01) non-linear association of higher levels of SAT with higher prevalence of fatigue was observed. Lower levels of SMR were linearly associated with higher prevalence of fatigue at 6 months post-diagnosis (overall associationp = 0.02). None of the body composition parameters were significantly associated with fatigue at 24 months.ConclusionHaving more SAT was associated with more fatigue at diagnosis, while low levels of SMR were associated with more fatigue at 6 months post-diagnosis.Implications for Cancer SurvivorsOur results suggest that it may be interesting to investigate whether interventions that aim to increase SMR around the time of diagnosis may help to lower fatigue. However, more knowledge is needed to understand the mechanisms behind the association of SMR with fatigue.

Published: October 2020

AbstractThe main goal of this paper is to provide an abstract framework for constructing proof systems for various many-valued logics. Using the framework it is possible to generate strongly complete proof systems with respect to any finitely valued deterministic and non-deterministic logic. I provide a couple of examples of proof systems for well-known many-valued logics and prove the completeness of proof systems generated by the framework.
Two Sides of the Same Coin or Two Different Currencies? Representations of Happiness and Unhappiness among Finnish Women

Published: October 2020

AbstractThis paper presents results from a study exploring representations of “happiness” and “unhappiness.” Word associations with these concepts were produced by 16–18 and 29–34-year-old women from Finland, the country that the United Nation’s World Happiness Report has ranked the “happiest” in the world. Correspondence Analysis (CA) and Hierarchical Cluster Analysis show that participants in both age groups share three clusters of words associated with “happiness”: Tangible happiness, Affective happiness and Serene happiness. We noted more differences in the associations with “unhappiness,” for which the two groups share only two clusters: Loss and Everyday problems. A distinct third cluster, Affective unhappiness, emerged for the younger women, whereas older women’s associations are further differentiated into a more complex structure, including two more clusters: Dejection and Apprehension. Additionally, CA shows that in both age groups, self-reported happiness levels do not discriminate which words are associated with happiness and unhappiness. Finally, qualitative content analysis of a questionnaire item investigating how to reach complete happiness suggested that there are three recurring answer types: happiness can be improved through external changes, internal changes, or not at all because complete/permanent happiness does not exist. The study provides a methodological design which, unlike most happiness studies, allows participants the freedom to bring up the meaning of happiness and unhappiness. Thus, the study constitutes a contribution to a more nuanced understanding of happiness.
