AbstractBackgroundPosterior shoulder instability is caused by structural or functional defects. While the former are mostly treated surgically, physiotherapy is considered the treatment of choice in functional shoulder instability. However, it often has limited success unless very specific and intensive training programs are applied by trained experts. Currently, there is no consensus on the treatment of functional posterior shoulder instability.ObjectiveTo improve treatment of this pathology, a standardized treatment recommendation is required to serve as a guideline for physiotherapy. The aim of this study was to establish expert consensus for treatment recommendations for functional posterior shoulder instability.DesignThe Delphi survey technique was employed.MethodsA standardized training program for treatment of functional posterior shoulder instability was developed by a local expert committee. Two rounds of an online Delphi survey were then conducted. The panel of the Delphi survey comprised nine leading scientific experts in the field of functional shoulder instability who treat patients with shoulder-related problems conservatively and operatively.ResultsThe response rate was 100% and there were no dropouts. The final program consists of three groups of exercises with increasing difficulty. The exercises are mostly easy to perform and focus on the scapula-retracting muscles and the muscles responsible for external rotation of the shoulder. The treatment program should be executed under the supervision of a therapist at the beginning and later may be performed by the patients themselves.ConclusionConsensus on a new exercise guideline dedicated to the treatment of functional posterior shoulder instability was achieved. This guideline should not only help to treat this challenging pathology but also provide a starting point for further scientific research and ongoing improvement.
Contiguity of proactive and reactive inhibitory brain areas: a cognitive model based on ALE meta-analyses
Authors: Gavazzi Gioele , Giovannelli Fabio , Currò Tommaso , Mascalchi Mario , Viggiano Maria Pia 
Published: August 2020

AbstractCognitive control is a critical feature in adapting our behavior to environmental and internal demands with two types of inhibition having been identified, namely the proactive and the reactive. Aiming to shed light on their respective neural correlates, we decided to focus on the cerebral activity before or after presentation of the target demanding a subject’s stop as a way to separate the proactive from the reactive components associated with the tasks. Accordingly, we performed three Activation Likelihood Estimation (ALE) meta-analyses of fMRI studies exploring proactive and reactive inhibitory phases of cognitive control. For this purpose, we searched for fMRI studies investigating brain activity preceding or following target stimuli. Eight studies (291 subjects, 101 foci) were identified for the proactive analysis. Five of these studies and those previously analyzed by others (348 subjects, 199 foci) were meta-analyzed to explore the neural correlates of reactive inhibition. Overall, our results showed different networks for the two inhibitory components. Notably, we observed a contiguity between areas in the right inferior frontal gyrus pertaining to proactive inhibition and in the right middle frontal gyrus regarding reactive inhibition. These neural correlates allow proposal of a new comprehensive model of cognitive control.

Local projections for high-dimensional outlier detection
Authors: Ortner Thomas , Filzmoser Peter , Rohm Maia , Brodinova Sarka , Breiteneder Christian 
Published: August 2020

AbstractA novel approach for outlier detection is proposed, called local projections, which is based on concepts of the Local Outlier Factor (LOF) (Breunig et al. in Lof: identifying density-based local outliers. In: ACM sigmod record, ACM, volume 29, pp. 93–104, 2000) and ROBPCA (Hubert et al. in Technometrics 47(1):64–79, 2005). By using aspects of both methods, this algorithm is robust towards noise variables and is capable of performing outlier detection in multi-group situations. The idea is to focus on local descriptions of the observations and their neighbors using linear projections. The outlyingness of an observation is determined by a weighted distance of the observation to all identified projection spaces, with weights depending on the appropriateness of the local description. Experiments with simulated and real data demonstrate the usefulness of this method when compared to existing outlier detection algorithms.

AbstractBone represents the second most common site of distant metastases in differentiated thyroid cancer (DTC). The clinical course of DTC patients with bone metastases (BM) is quite heterogeneous, but generally associated with low survival rates. Skeletal-related events might be a serious complication of BM, resulting in high morbidity and impaired quality of life. To achieve disease control and symptoms relief, multimodal treatment is generally required: radioiodine therapy, local procedures—including surgery, radiotherapy and percutaneous techniques—and systemic therapies, such as kinase inhibitors and antiresorptive drugs. The management of DTC with BM is challenging: a careful evaluation and a personalized approach are essential to improve patients’ outcomes. To date, prospective studies focusing on the main clinical aspects of DTC with BM are scarce; available analyses mainly include cohorts assembled over multiple decades, small samples sizes and data about BM not always separated from those regarding other distant metastases. The aim of this review is to summarize the most recent evidences and the unsolved questions regarding BM in DTC, analyzing several key issues: pathophysiology, prognostic factors, role of anatomic and functional imaging, and clinical management.
Hodge theorem for the logarithmic de Rham complex via derived intersections
Authors: Hablicsek Márton 
Published: August 2020

AbstractIn a beautiful paper, Deligne and Illusie (Invent Math 89(2):247–270, 1987) proved the degeneration of the Hodge-to-de Rham spectral sequence using positive characteristic methods. Kato (in: Igusa (ed) ALG analysis, geographic and numbers theory, Johns Hopkins University Press, Baltimore, 1989) generalized this result to logarithmic schemes. In this paper, we use the theory of twisted derived intersections developed in Arinkin et al. (Algebraic Geom 4:394–423, 2017) and the author of this paper to give a new, geometric interpretation of the Hodge theorem for the logarithmic de Rham complex.

Abstract
The discovery of laser-induced graphene (LIG) from polymers in 2014 has aroused much attention in recent years. A broad range of applications, including batteries, catalysis, sterilization, and separation, have been explored. The advantages of LIG technology over conventional graphene synthesis methods are conspicuous, which include designable patterning, environmental friendliness, tunable compositions, and controllable morphologies. In addition, LIG possesses high porosity, great flexibility, and mechanical robustness, and excellent electric and thermal conductivity. The patternable and printable manufacturing process and the advantageous properties of LIG illuminate a new pathway for developing miniaturized graphene devices. Its use in sensing applications has grown swiftly from a single detection component to an integrated smart detection system. In this minireview, we start with the introduction of synthetic efforts related to the fabrication of LIG sensors. Then, we highlight the achievement of LIG sensors for the detection of a diversity of stimuli with a focus on the design principle and working mechanism. Future development of the techniques toward in situ and smart detection of multiple stimuli in widespread applications will be discussed.
Mediate relation between electrical and thermal conductivity of soil
Authors: Schwarz Hans , Bertermann David 
Published: August 2020

AbstractThermal conductivity is a key parameter for many soil applications, especially for dimensioning shallow and very shallow geothermal systems based on the possible heat extraction rate and for modelling heat transfer processes around high voltage underground cables. Due to the limited purview of direct thermal conductivity measurements, for an investigation of extensive areas, usually other geophysical methods like electrical resistivity tomography measurements are applied. To derive thermal conductivity of soil from geoelectrical measurements a relation between electrical and thermal conductivity is needed. Until now only few approaches worked on a direct correlation between both conductivities. Due to the difficulties of a direct relation, within this study a modular approach of a mediate correlation between electrical and thermal conductivity was investigated. Therefore, a direct relationship between a corrected electrical conductivity and water content as well as the standard and simple thermal conductivity model of Kersten (Bull of the Univ Minnesota 28:1–227, 1949) was used. To develop this concept soil types of sand, silt loam and clay were investigated where different saturation steps and pressure loads were applied. For each configuration electrical and thermal conductivity as well as water content and bulk density was determined. To refine the results of the calculated water content a corrective factor was applied. Furthermore, bulk density as an inlet parameter of the Kersten equation was also derived based on electrical conductivity. The suggested proceeding enables the determination of thermal conductivity solely based on electrical conductivity without prior soil property information.
Investigating reconstructed inflows and pathogen infection patterns between low-relief and high-relief subtropical oyster reefs

Published: August 2020

AbstractFlood and drought events cause significant freshwater inflow fluctuations in estuaries, potentially leading to physiological stress and altered abundances of pathogens such as Vibrio vulnificus and Perkinsus marinus in oysters. To assess the effects of freshwater pulses to oyster reefs in subtropical estuaries in Texas, this study accomplished two goals: 1) reconstructed a reef-specific history of freshwater pulses through shell stable isotope analysis, 2) quantified the abundance of V. vulnificus and P. marinus through culture-dependent and culture-independent microbiology analyses. Oysters from a low-relief and high-relief reef experienced similar fluctuations in shell isotopes, indicating similar ranges of past environmental conditions. V. vulnificus and P. marinus were detected throughout the study but the abundance of these microorganisms was not correlated with environmental parameters or one another. Importantly, the P. marinus infection intensity was always lower at the high-relief reef, which suggests that high-relief reefs may experience lower infection frequencies.
We must rigorously follow basic infection control procedures to protect our healthcare workers from SARS-CoV-2
Authors: Dooley Samuel W. , Frieden Thomas R. 
Published: August 2020

AbstractBecause severe acute respiratory coronavirus virus 2 (SARS-CoV-2) spreads easily and healthcare workers are at increased risk of both acquiring and transmitting infection, all healthcare facilities must rapidly and rigorously implement the full hierarchy of established infection controls: source control (removal or mitigation of infection sources), engineering and environmental controls, administrative controls, and personal protective equipment.

AbstractAs the coronavirus disease 2019 (COVID-19) continues to circulate, testing strategies are of the utmost importance. Given national shortages of testing supplies, personal protective equipment, and other hospital resources, diagnostic stewardship is necessary to aid in resource management. We report the low utility of serial testing in a low-prevalence setting.

AbstractObjectives:Prolonged survival of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on environmental surfaces and personal protective equipment may lead to these surfaces transmitting this pathogen to others. We sought to determine the effectiveness of a pulsed-xenon ultraviolet (PX-UV) disinfection system in reducing the load of SARS-CoV-2 on hard surfaces and N95 respirators.Methods:Chamber slides and N95 respirator material were directly inoculated with SARS-CoV-2 and were exposed to different durations of PX-UV.Results:For hard surfaces, disinfection for 1, 2, and 5 minutes resulted in 3.53 log10, >4.54 log10, and >4.12 log10 reductions in viral load, respectively. For N95 respirators, disinfection for 5 minutes resulted in >4.79 log10 reduction in viral load. PX-UV significantly reduced SARS-CoV-2 on hard surfaces and N95 respirators.Conclusion:With the potential to rapidly disinfectant environmental surfaces and N95 respirators, PX-UV devices are a promising technology to reduce environmental and personal protective equipment bioburden and to enhance both healthcare worker and patient safety by reducing the risk of exposure to SARS-CoV-2.
Children, seen and heard: a descriptive study of all children (aged 12 years and under) referred for acute psychiatric assessment in Tallaght University Hospital over a 10-year period
Authors: Maguire E. , Glynn K. , McGrath C. , Byrne P. 
Published: August 2020

AbstractObjectives:A review of the literature demonstrates that relatively little is known about acute psychiatric presentations in children (0–12 years), compared with adolescents or young adults (12 years+). This study aims to review psychiatric presentations of children to a CAMHS Liaison Service at Children’s Hospital Ireland (CHI) at Tallaght University Hospital over a 10-year period.Methods:A retrospective study was undertaken of case notes of all children aged 12 years and under who were referred to the CAMHS Liaison Service between January 2009 and December 2018 (n = 318). Data were anonymised and inputted into SPSSv25 for analysis. The relationships between presentations and methods of self-harm over time were measured using Pearson’s correlation. Associations between categorical variables were analysed using chi-squared tests.Results:There was a significant increase in presentations of under-12s over the 10-year period (r(8)=0.66, p = 0.02). There was also a significant increase in children presenting with a disturbance of conduct and/or emotions over time (r(8) = 0.79, p < 0.001). There was a significant association between female gender and ingestion (X2 = 12.73, df = 1, p < 0.05) and between male gender and ligature as a method of self-harm (X2 = 5.54, df = 1, p < 0.05). Over half (53%) of children presented with suicidal thoughts and 22% presented with suicidal behaviours. The reported use of ligature as a method of self-harm emerged only from 2012 among cases studied.Conclusions:Children aged 12 years and under are presenting in increasing numbers with acute mental health difficulties, including suicidal thoughts and behaviours. There is a worrying trend in methods of self-harm, particularly in high lethality behaviours such as attempted strangulation.
Annual cycle in flow of Ross Ice Shelf, Antarctica: contribution of variable basal melting

Published: August 2020

AbstractIce shelves play a critical role in modulating dynamic loss of ice from the grounded portion of the Antarctic Ice Sheet and its contribution to sea-level rise. Measurements of ice-shelf motion provide insights into processes modifying buttressing. Here we investigate the effect of seasonal variability of basal melting on ice flow of Ross Ice Shelf. Velocities were measured from November 2015 to December 2016 at 12 GPS stations deployed from the ice front to 430 km upstream. The flow-parallel velocity anomaly at each station, relative to the annual mean, was small during early austral summer (November–January), negative during February–April, and positive during austral winter (May–September). The maximum velocity anomaly reached several metres per year at most stations. We used a 2-D ice-sheet model of the RIS and its grounded tributaries to explore the seasonal response of the ice sheet to time-varying basal melt rates. We find that melt-rate response to changes in summer upper-ocean heating near the ice front will affect the future flow of RIS and its tributary glaciers. However, modelled seasonal flow variations from increased summer basal melting near the ice front are much smaller than observed, suggesting that other as-yet-unidentified seasonal processes are currently dominant.
ESTIMATION OF THE OCCURRENCE TIME OF THE Δ14C PEAK IN AD 775 BASED ON THE OXIDATION TIME OF 14C IN THE ATMOSPHERE AND Δ14C VALUES IN SUBANNUAL TREE RINGS
Authors: Park Junghun , Seo Jeong-Wook , Hong W , Park G , Sung Kilho , Park Yong Jin , Kim Yo-Jung 
Published: August 2020

ABSTRACTThe 14C peak in AD 775 (M12) has been measured and confirmed globally in several studies since it was first measured in annual tree rings by Miyake et al. (2012). However, M12 data measurements in early- and latewood are limited. This paper presents the Δ14C values in early- and latewood from AD 762–776 Zelkova serrata tree rings from Bangu-dong, Ulsan, South Korea (35°33′N, 129°20′E). The results indicate no early rise in Δ14C values in the latewood of AD 774 in this sample located at mid-latitude. A comparison of the results of this and previous studies suggests latitude dependence (Büntgen et al. 2018); that is, the early rise of Δ14C in AD 774 was not observed at mid-latitudes in South Korea but was observed at high latitudes in Finland. The half-oxidation time of 14C was estimated from a detailed analysis of a small bomb peak in AD 1962. Based on the half-oxidation time, the Δ14C rise in the latewood, but not in the earlywood, of AD 774 in Finland, and the absence of a Δ14C rise in both the early- and latewood of AD 774 in South Korea, the 14C spike was estimated to have been produced from late April to mid-June in AD 774.
Appropriations of Gregorian Chant inFin-de-siècleFrench Opera:Couleur locale– Message-Opera – Allusion?
Authors: LESSMANN BENEDIKT 
Published: August 2020

AbstractThis article compares three French operas from thefin de sièclewith regard to their appropriation of Gregorian chant, examining their different ideological and dramaturgical implications. In Alfred Bruneau’sLe rêve(1891), the use of plainchant, more or less in literal quotation and an accurate context, has often been interpreted as naturalistic. By treating sacred music as a world of its own, Bruneau refers to the French idea of Gregorian chant as ‘other’ music. In Vincent d’Indy’sL’étranger(1903), a quotation ofUbi caritasdoes not serve as an occasional illustration, but becomes essential as part of the leitmotif structure, thus functioning as the focal point of a religious message. Jules Massenet’sLe jongleur de Notre-Dame(1902) provides a third way of using music associated with history and Catholicism. In this collage of styles, plainchant is not quoted literally, but rather alluded to, offering in this ambiguity a mildly anti-clerical satire.
The role of ecological opportunity in shaping host–parasite networks

Published: August 2020

AbstractDespite the great interest to quantify the structure of host–parasite interaction networks, the real influence of some factors such as taxonomy, host body size and ecological opportunity remains poorly understood. In this paper, we investigate the general patterns of organization and structure of interactions in two anuran–parasite networks in the Brazilian Pantanal (seasonally flooded environment) and Atlantic Forest (non-flooded forest). We present theoretical models to test whether the structures of these host–parasite interaction networks are influenced by neutrality, host taxonomy and host body size. Subsequently, we calculated metrics of connectance, nestedness and modularity to characterize the network structure. We demonstrated the structure networks were influenced mainly by body size and taxonomy of the host. Moreover, our results showed that the seasonally flooded environment present networks with higher connectance/nestedness and lower modularity compared to the other environment. The results also suggest that seasonal floods may promote ecological opportunities for new species associations.
