Diagnosis and management of arrhythmias in dogs: A cross‐sectional online survey among Flemish veterinary practitioners
Authors: Hellemans Arnaut , Schittekatte Mark , Covents Marc , Smets Pascale 
Published: April 2022

AbstractBackgroundDiagnosis as well as management of arrhythmias in dogs can be challenging for veterinary practitioners. The aim was to describe ECG availability and use, as well as the diagnostic and therapeutic experiences and preferences of Flemish veterinarians regarding cardiac arrhythmias in dogs.MethodsCross‐sectional online survey among veterinarians in Flanders (Belgium).ResultsAn ECG device was available for 55 out of 102 respondents (54%) and 41 (43%) claimed to use it in case of arrhythmia suspicion. Insufficient knowledge about ECG interpretation and immediate patient referral upon detection of an abnormal heart rhythm were the most important reasons for not having, or not using, an ECG. About half of the respondents (56%) had never used anti‐arrhythmic drugs in dogs, although only a few reported having had a negative experience. Frequently provided reasons for not using anti‐arrhythmic drugs included insufficient knowledge and a low number of dogs with arrhythmias.ConclusionMost veterinarians reported having little or no expertise with arrhythmias in dogs. Electrocardiogram availability and use among respondents was moderate and too often restricted by insufficient ECG interpretation skills. Continued efforts are needed to increase the confidence and knowledge of veterinarians about arrhythmias in dogs.

ZusammenfassungInfektionen mit dem „severe acute respiratory syndrome coronavirus 2“ (SARS-CoV-2) können zu einer Multiorganerkrankung und in der Folge zu sehr unterschiedlichen klinischen Manifestationen der „coronavirus disease 2019“ (COVID-19) führen. Neben akuten Symptomen kommt den Langzeitbeschwerden im Kontext der Infektion vermehrte Aufmerksamkeit zu, man spricht vom Long- oder Post-COVID-Syndrom. Mit Blick auf die Sozialversicherungssysteme werden gutachterliche Beurteilungen solcher Gesundheitsprobleme zunehmend an Bedeutung gewinnen, wobei neurologische und psychiatrische Symptome die häufigsten Beschwerden sind. Neben rechtlichen Grundlagen der medikolegalen Begutachtung mit Schwerpunkt auf der gesetzlichen Unfallversicherung werden in der vorliegenden Übersicht grundlegende Aspekte der Begutachtung diskutiert und Orientierungshilfen für die Begutachtung der häufigsten neurologischen und psychiatrischen Symptome des Post-COVID-Syndroms geboten.
Patterns of value creation in policy-driven cluster initiatives: evidence from the croatian competitiveness clusters
Authors: Anić Ivan-Damir , Corrocher Nicoletta 
Published: April 2022

AbstractThis paper investigates the value creation process in policy-driven cluster initiatives that are important policy tools for implementing Smart specialisation strategies. It aims at studying the evolution of the Croatian Competitiveness Clusters (CCC) to understand the role of sectoral specificities in affecting value creation within cluster initiatives. In this context, it looks at what services cluster initiatives should deliver to meet the expectations of members and generate value and what modes of cluster management and governance are the most conducive to value creation across different industries. The analysis relies on a survey of 250 CCC members. The results show that members’ preferences for support to the business activities are associated with different levels of perceived value creation. High-value CCC members are interested in innovation, infrastructure development, market analysis and training, while low-value CCC members are interested in lobbying and networking. Regardless of the sector, CCC with a higher share of private, small, and high-growth firms are more likely to generate public value by pursuing long-term activities with the emphasis on innovation, knowledge transfer, infrastructure, and market development, as compared to CCC with a high share of declining firms that see CCC as a platform for lobbying and networking and as such generate more private value, failing to achieve their ultimate goal. A high level of value is also created if members reach a consensus on the vision and activities of the CCC and work together to share knowledge, information and learning processes.

Published: April 2022

AbstractIn this work we study from the mathematical and numerical point of view a problem arising in vector-borne plant diseases. The model is written as a nonlinear system composed of a parabolic partial differential equation for the vector abundance function and a first-order ordinary differential equation for the plant health function. An existence and uniqueness result is proved using backward finite differences, uniform estimates and passing to the limit. The regularity of the solution is also obtained. Then, using the finite element method and the implicit Euler scheme, fully discrete approximations are introduced. A discrete stability property and a main a priori error estimates result are proved using a discrete version of Gronwall’s lemma and some estimates on the different approaches. Finally, some numerical results, in one and two dimensions, are presented to demonstrate the accuracy of the approximation and the behaviour of the solution.
Probabilistic assessment of footbridge response to single walkers
Authors: Picozzi V. , Avossa A. M. , Ricciardelli F. 
Published: April 2022

AbstractAmong the load scenarios considered for the serviceability assessment of human-induced footbridge vibration, is that of the transient action of a single pedestrian or a small group of pedestrians. Although such action is stochastic due to the variability of gait parameters, available Codes and Guidelines all assume it is deterministic and equal to that coming from the “worst pedestrian ever” for the given footbridge. This approach is sound from an engineering point of view but does not allow control of the probability of failure. The present work deals with a reliability-based procedure for the serviceability assessment of the footbridge peak characteristic accelerations due to pedestrian induced actions. Based on the results obtained incorporating the effects of the inter-subject variability of gait parameters and of the uncertainties in footbridge dynamic properties, a design response spectrum is proposed for both vertical and lateral vibrations. The proposed procedure lends itself for immediate Code implementation.
Renal blood flow and oxygenation
Authors: Edwards Aurelie , Kurtcuoglu Vartan 
Published: April 2022

AbstractOur kidneys receive about one-fifth of the cardiac output at rest and have a low oxygen extraction ratio, but may sustain, under some conditions, hypoxic injuries that might lead to chronic kidney disease. This is due to large regional variations in renal blood flow and oxygenation, which are the prerequisite for some and the consequence of other kidney functions. The concurrent operation of these functions is reliant on a multitude of neuro-hormonal signaling cascades and feedback loops that also include the regulation of renal blood flow and tissue oxygenation. Starting with open questions on regulatory processes and disease mechanisms, we review herein the literature on renal blood flow and oxygenation. We assess the current understanding of renal blood flow regulation, reasons for disparities in oxygen delivery and consumption, and the consequences of disbalance between O2 delivery, consumption, and removal. We further consider methods for measuring and computing blood velocity, flow rate, oxygen partial pressure, and related parameters and point out how limitations of these methods constitute important hurdles in this area of research. We conclude that to obtain an integrated understanding of the relation between renal function and renal blood flow and oxygenation, combined experimental and computational modeling studies will be needed.
Implication in finite posets with pseudocomplemented sections
Authors: Chajda Ivan , Länger Helmut 
Published: April 2022

AbstractIt is well-known that relatively pseudocomplemented lattices can serve as an algebraic semantics of intuitionistic logic. To extend the concept of relative pseudocomplementation to non-distributive lattices, the first author introduced so-called sectionally pseudocomplemented lattices, i.e. lattices with top element 1 where for every elementythe interval [y, 1], the so called section, is pseudocomplemented. We extend this concept to posets with top element. Our goal is to show that such a poset can be considered as an algebraic semantics for a certain kind of more general intuitionistic logic provided an implication is introduced as shown in the paper. We prove some properties of such an implication. This implication is “unsharp” in the sense that the value for given entries need not be a unique element, but may be a subset of the poset in question. Using this implication we show that we can even recover the order of the original poset. Further, a new “unsharp” operator$$\odot $$⊙of conjunction can be introduced which is adjoint to “unsharp” implication and hence we obtain an “unsharp” residuated poset.
Energiepreiskrise und Kriegssanktionen — die Energieversorgung von morgen
Authors:   Ueberblick
Published: April 2022

ZusammenfassungDie Gas- und Rohölpreise sind in den vergangenen Monaten kontinuierlich gestiegen. Außerdem erhöht der Krieg in der Ukraine die Unsicherheit auf den Energiemärkten. Die von der EU und verbündeten Staaten gegen Russland verhängten Sanktionen könnten mittelbar auch Folgen auf die Versorgungssicherheit in Deutschland haben. Hier scheint insbesondere unsicher, ob oder in welchem Umfang weiterhin Gas aus Russland importiert werden kann. Vor welchen Herausforderungen steht die deutsche Politik jetzt und welche Maßnahmen sollte sie ergreifen, um Versorgungssicherheit, Preisstabilität und Energiewende nicht zu gefährden? Gibt es sinnvolle Substitute für russisches Gas? Welche Energieträger sollten in dieser Situation ausgebaut werden?
Wie man die Auswirkungen eines Gasembargos berechnen könnte
Authors: Krebs Tom 
Published: April 2022

AbstractIn this essay, I outline a method to compute the economic impact of a sudden stop of natural gas imports from Russia. First, I estimate the reduction in the short-run supply of natural gas for the economy and the industry sector. Second, I use model simulations to analyse the effect of a sudden import stop on the industry sectors using natural gas and the whole economy. The model should take into account the limited short-run substitution possibilities of the industry sectors using natural gas (chemical industry) and the value chain linkages of these sectors with all other sectors of the economy. The recent analysis by Bachmann et al. (2022) does not satisfy these two methodological conditions and the results should be interpreted accordingly.
Coronapandemie: Auswirkungen auf den Einzelhandel in den Innenstädten
Authors: Goecke Henry , Rusche Christian 
Published: April 2022

ZusammenfassungDie Auswirkungen der Pandemie sind in allen Wirtschaftsbereichen spürbar. Ein Bereich, der am stärksten durch Schließungen, Einschränkungen und ein verändertes Verbraucher:innenverhalten betroffen war und bleibt, ist der innerstädtische Einzelhandel. Tatsächlich wird an der Passantenfrequenz in ausgewählten Städten der zum Teil dramatische Rückgang an potenziellen Kund:innen deutlich. In den statistischen Umsatzzahlen zum gesamten Einzelhandel wird dies nicht adäquat abgebildet. Eine nähere Betrachtung innerstädtischer Einzelhandelsbereiche offenbart, dass trotz erhöhter Nutzung von E-Commerce-Kanälen der Umsatz noch unter dem Vor-Corona-Niveau liegt. Zudem profitieren einzelne Bereiche stark, während andere dramatisch eingebüßt haben. Durch somit ausgelöste Geschäftsaufgaben kann jedoch die Attraktivität der Innenstadt als Ganzes sinken, weshalb auch Bereiche, welche die Krise bisher meistern konnten, am Ende mit sinkenden Umsätzen konfrontiert sein könnten.
Das Problem des subjektiven Werturteils
Authors: Hüther Michael 
Published: April 2022

ZusammenfassungIn der politischen Debatte um die richtige Reaktion des Westens auf den russischen Angriffskrieg auf die Ukraine steht neben den bereits beschlossenen Sanktionen ein sofortiges Gasembargo als Mittel im Raum, um den wirtschaftspolitischen Druck auf Russland zu erhöhen. Hier ist insbesondere ökonomische Expertise nötig, um die Politik in dieser Entscheidung zu beraten und die möglichen Kosten und Risiken für Deutschland transparent zu machen. Dabei sind die unvermeidlich zu setzenden subjektiven Werturteile offenzulegen. Auch muss differenziert über die Grenzen makroökonomischer Modelle gesprochen werden.

Betriebliche Belastungen durch Ukrainekrieg
Authors: Grömling Michael , Bardt Hubertus 
Published: April 2022

ZusammenfassungDer Krieg in der Ukraine bringt erhebliche Belastungen für die deutsche Wirtschaft mit sich. Auf Basis der Konjunkturumfrage des Instituts der deutschen Wirtschaft können die verschiedenen Übertragungswege und Auswirkungen eingeschätzt werden. Fast 80% der Unternehmen sehen sich derzeit durch hohe Energiepreise belastet. Über 40% erwarten, dass sie kurzfristig in ihren Geschäftsabläufen durch ausfallende Lieferungen von Vorleistungen beeinträchtigt werden; ebenso hoch ist die erwartete Belastung durch drohende Engpässe in der Energieversorgung. Seit der ersten Befragung in der ersten Märzhälfte 2022 haben sich die Sorgen tendenziell erhöht. Für die mittlere Frist werden weiter ansteigende Belastungen durch den Krieg für die Unternehmen erwartet.
Device therapy with interatrial shunt devices for heart failure with preserved ejection fraction
Authors: Nanayakkara Shane , Kaye David M. 
Published: April 2022

AbstractHeart failure with preserved ejection fraction is responsible for half of all heart failure and confers substantial morbidity and mortality, and yet to date, there have been no effective pharmacologic interventions. Although the pathophysiology is complex, the primary aetiology of exercise intolerance is due to an elevated left atrial pressure, particularly with exercise. In this context, device-based therapy has become a focus. Several companies have developed techniques to percutaneously create an iatrogenic left to right shunt at the atrial level, thereby reducing left atrial pressure and reducing transmitted pressures to the pulmonary circulation and reducing pulmonary congestion. In this review, we explore the pathophysiology, evidence base, benefits, and considerations of these devices and their place in the therapeutic landscape of heart failure with preserved ejection fraction.

AbstractIn mammals, olfactory communication plays an essential role in territorial and mating dynamics. Scent depositions in various species, including lemurs, can be placed via marking or overmarking (marking over previous depositions). We focused on the role that marking and overmarking play in territorial defence and intrasexual competition. We investigated these aspects in diademed sifaka (Propithecus diadema) in the primary rainforest of Maromizaha (eastern Madagascar). We collected scent marking data for five groups from April to November 2018 and from May to December 2019. We aimed to understand whether the lemurs deposited scent marks homogeneously across the home range and whether sex, rank, and occurrence of intergroup encounters affected the lemur’s deposition rate. We also asked whether males overmarked adult females more often than other depositions, and the marking and overmarking rates changed between the migration and non-migration seasons. We found that scent marking was performed higher in peripheral and overlapping areas than in the home range central areas. In addition, males had higher scent marking rates, but intergroup encounters did not affect deposition rates. Males showed higher rates of overmarking and primarily targeted dominant females’ depositions, particularly during the “migration” season (including premating and mating seasons). Our findings suggest a border-marking strategy in Propithecus diadema. More frequent scent marking in the “migration” season suggests intrasexual competition in males. Our results suggest that marking is associated with territorial and resource defence, suggesting that it plays a role in monopolizing females using a mate-guarding strategy and may also serve for males’ self-advertisement to females and subordinate depositors.
A multivariate extension of the Lorenz curve based on copulas and a related multivariate Gini coefficient
Authors: Grothe Oliver , Kächele Fabian , Schmid Friedrich 
Published: April 2022

AbstractWe propose an extension of the univariate Lorenz curve and of the Gini coefficient to the multivariate case, i.e., to simultaneously measure inequality in more than one variable. Our extensions are based on copulas and measure inequality stemming from inequality in each single variable as well as inequality stemming from the dependence structure of the variables. We derive simple nonparametric estimators for both instruments and exemplary apply them to data of individual income and wealth for various countries.
High Performance of UiO-66 Metal–Organic Framework Modified with Melamine for Uptaking of Lead and Cadmium from Aqueous Solutions

Published: April 2022

Abstract
In this paper, UiO-66 metal–organic framework (MOF) was prepared by a hydrothermal method and modified consequently with melamine (MUiO-66), as so as enhance the adsorption properties of these materials in liquid-phase adsorption. With respect to this, the adsorption of lead and cadmium divalent ions was performed under varying conditions of pH, metal ion concentration, contact time, adsorbent dose and temperature. Morphology, texture properties, functional groups, crystallinity and thermal properties of both MOFs were examined. UiO-66 composed of sphere-like particles and covered by layers of melamine with enhancing in crystallinity and active sites as well as the total surface area increased from 1080 to 1160 m2/g. The modified UiO-66 with melamine (MUiO-66) showed a notable adsorption capacity of 177.5 and 146.6 mg/g for Pb and Cd(II) ions, respectively. Adsorption of both metals fitted well with the pseudo-second-order kinetic and Langmuir models and controlled by a physisorption mechanism at pH of 5. Also, adsorption process is an endothermic in nature and desorption is achieved well for three cycles by MUiO-66. Therefore, UiO-66 and MUiO-66 obtained in this work have a great promise in adsorption of heavy metals such as Pb and Cd(II) ions from wastewater.
SWprocess: a workflow for developing robust estimates of surface wave dispersion uncertainty
Authors: Vantassel Joseph P. , Cox Brady R. 
Published: April 2022

AbstractNon-invasive surface wave methods are increasingly being used as the primary technique for estimating a site’s small-strain shear wave velocity (Vs). Yet, in comparison to invasive methods, non-invasive surface wave methods suffer from highly variable standards of practice, with each company/group/analyst estimating surface wave dispersion data, quantifying its uncertainty (or ignoring it in many cases), and performing inversions to obtain Vs profiles in their own unique manner. In response, this work presents a well-documented, production-tested, and easy-to-adopt workflow for developing estimates of experimental surface wave dispersion data with robust measures of uncertainty. This is a key step required for propagating dispersion uncertainty forward into the estimates of Vs derived from inversion. The paper focuses on the two most common applications of surface wave testing: the first, where only active-source testing has been performed, and the second, where both active-source and passive-wavefield testing has been performed. In both cases, clear guidance is provided on the steps to transform experimentally acquired waveforms into estimates of the site’s surface wave dispersion data and quantify its uncertainty. In particular, changes to surface wave data acquisition and processing are shown to affect the resulting experimental dispersion data, thereby highlighting their importance when quantifying uncertainty. In addition, this work is accompanied by an open-source Python package, swprocess, and associated Jupyter workflows to enable the reader to easily adopt the recommendations presented herein. It is hoped that these recommendations will lead to further discussions about developing standards of practice for surface wave data acquisition, processing, and inversion.

Published: April 2022

AbstractMicrotremor array measurements, and passive surface wave methods in general, have been increasingly used to non-invasively estimate shear-wave velocity structures for various purposes. The methods estimate dispersion curves and invert them for retrieving S-wave velocity profiles. This paper summarizes principles, limitations, data collection, and processing methods. It intends to enable students and practitioners to understand the principles needed to plan a microtremor array investigation, record and process the data, and evaluate the quality of investigation result. The paper focuses on the spatial autocorrelation processing method among microtremor array processing methods because of its relatively simple calculation and stable applicability.Highlights1.
