Authors: Ohlig Stefan , Breitkreuz David , Aliyu Aliyu , Mishra Rakesh , Stegelmeyer Dirk 
Published: July 2024

Abstract
The aim of this paper is to develop design options for Augmented Reality (AR)-based remote service business models to support the implementation of AR technology for remote services currently taking place in the manufacturing industry. The design options were developed using a qualitative content analysis based on the results of a systematic literature review and on focus group discussions with 19 service-responsible industry experts from 12 German manufacturing companies. The application of a conceptual approach to taxonomy development resulted in a novel morphological framework with a total of 18 dimensions, each with two to six distinct characteristics representing the targeted design options of AR-based remote service business models. Since previous research on AR for remote services has largely neglected the business model perspective, this work makes a significant contribution to this scarcely explored research field by providing a systematic basis for describing and classifying such business models in terms of their design. The results provide industrial practice with the most important aspects to consider when designing AR-based remote service business models.

Published: July 2024

Summary
The current study evaluated the effect of microbial-derived insecticides (abamectin and spinosad), two microbials (Beauveria bassiana (Balsamo) Vuillemin, Bacillus thuringiensis Berliner), and three chitin synthesis inhibitors (CSIs) (chlorfluazuron, hexaflumuron and lufenuron) against Spodoptera frugiperda larvae. Spinosad and abamectin caused pronounced mortality against second larval instar of S. frugiperda using the leaf dipping method. Spinosad induced higher toxicity (LC50 = 4.01 mg/L) than abamectin (LC50 = 8.33 mg/L) one day after treatment. The treatments with B. bassiana and B. thuringiensis caused higher mortality of S. frugiperda larvae 7 days after treatment with LC50 values of 3.0 × 105 spores/ml and 8.2 × 106 cells/ml, respectively. In the case of the CSIs, hexaflumuron showed higher toxicity than chlorfluazuron and lufenuron with LC50 values of 0.01, 0.009 and 0.005 mg/L 3, 7 and 10 days after treatment, respectively.

Authors: Saad M.M.G. , Abdelgaleil S.A.M. 
Published: July 2024

Summary
Five fungal endophytes, Alternaria sp., Aspergillus sp., Chaetomium sp., Rhizopus sp. and Curvularia sp., were isolated from an Egyptian herbaceous plant, Tribulus terrestris, and tested for their antibacterial activity against three phytopathogenic bacteria (Pectobacterium carotovorum subsp. carotovorum, Ralstonia solanacearum, Pseudomonas syringae pv. syringae). Chaetomium sp. showed the highest antibacterial activity. This strain was identified morphologically and molecularly as Chaetomium cochliodes MS03 (MW898133) based on the ITS1-5.8S rRNA-ITS2 genomic region. Chaetomium cochliodes caused 15 and 8 mm inhibition zones of P. carotovorum subsp. carotovorum and R. solanacearum, respectively. Chaetomium cochliodes isolate was fermented and extracted with ethyl acetate. The crude extract of C. cochliodes showed strong antibacterial activity against P. carotovorum subsp. carotovorum (inhibition zone = 27 mm). Bioassay guided isolation of the crude extract using silica gel column chromatography was conducted to isolate bioactive secondary metabolites. Minimum inhibitory concentrations (MICs) were 500, 32 and 4 mg/L for C. cochliodes extract, fraction 14 and fraction 15, respectively, against P. carotovorum subsp. carotovorum. Bioactive fractions were analyzed by GC/MS. The bioactive pure compound was identified as 9,12-octadecadienoic acid (Z,Z) and the chemical structure was confirmed by H1 NMR and C13 NMR spectral analysis. The isolated compound showed a promising antibacterial activity against P. carotovorum subsp. carotovorum with MIC value of 32 mg/L.
First record of Hyphopichia burtonii isolated from the storage pest Sitophilus zeamais and its bioactivity against mycotoxigenic fungi

Published: July 2024

Summary
Corn weevil (Sitophilus zeamais) is one of the most destructive pests of corn seeds during storage. The weevil may be a vector of mycotoxigenic fungi or yeast contaminating seed lots. In this study, an unknown yeast species was isolated from corn weevils found in stored corn seeds. We hypothesized that this yeast had an antifungal activity thereby inhibiting growth of mycotoxigenic fungi in corn seeds. The yeast species was identified as Hyphopichia burtonii, using combined morphological and molecular assays, and its potential inhibitory activity was assessed in vitro (spread plate and dual culture) against three known mycotoxigenic fungi, Fusarium verticillioides, Aspergillus niger and A. fl avus. Screening of the antagonistic activity of the yeast isolate showed 50 – 69% colony growth inhibition of three fungi when the yeast was spread plated on PDA but only slight inhibition (5.8 – 13.7% growth inhibition) in the dual culture assay. The sporulation of the fungi was also affected at 57 – 96% and 29 – 40% in spread plating and dual culture assay, respectively. In addition, volatile and non-volatile fractions also showed a reduction in mycelial growth. Variable responses were observed among the mycotoxigenic fungi. Further research would be interesting on the potential utilization of the antagonistic yeast to reduce fungal growth and sporulation, and possible mitigation of mycotoxin contamination in corn grains. To our knowledge, this is the first record of H. burtonii isolated from an insect, specifically S. zeamais.

Summary
The spotted wing drosophila, Drosophila suzukii (Matsumura, 1931), population fluctuations and distribution were monitored in four susceptible crops (blueberry, strawberry, cherry, wine grapes) and five major agricultural regions of Georgia (Guria, Samegrelo, Imereti, Kartli and Kakheti) during the years 2021 and 2022 with the aim to study the population size and evaluate the pest status. Population monitoring was conducted in four locations of each studied region on a weekly basis from May to November using PHEROCON® SWD traps with PHEROCON® SWD PEEL-PAK™ Broad Spectrum Lures. The investigation indicated significant growth of population from 2021 to 2022 in most of the studied locations. Population increase was detected in all crop orchards except cherries. Τhe absence of alternative host plants at crop proximity was of critical importance to save the crop from pest invasion. The crop plant species did not have a significant impact on D. suzukii. Pest population was significantly larger in summer and autumn compared to spring, possibly influenced by the ripening of alternative crops such as blackberry and elderberry. The sex ratio between male and female individuals was almost 1:1 and remained consistent through the two-year study period and across regions. We consider that D. suzukii entered the country from the southwestern part and extended its distribution range towards the east. No strategies for D. suzukii control have been elaborated in Georgia so far. Sprays of effective pesticides based on pest monitoring as well as sanitation measures involving removal of alternative host plants and any crop residues from the field are necessary to avoid pest outbreak.
Implementation of Classical Motion Cueing Algorithms for Serial Manipulator Based Motion Simulator: Larrmos Case Study
Authors: Stupans A. , Maksimkins P. , Senfelds A. , Ribickis L. 
Published: July 2024

Abstract
The study focuses on the development and evaluation of a motion control system for the Large Range Robotic Motion Simulator (LaRRMoS), which is based on a serial manipulator with 6 degrees-of-freedom. Two motion cueing algorithms (MCAs) – Classical Washout Filter (CWF) and Classical Washout Filter with Cylindrical coordinates (CYL) – are implemented and tested for simulation fidelity and LaRRMoS workspace utilization. CWF and CYL motion cueing performance gets assessed in two use cases: car simulation and luge sports simulation. The car case is a typical driving simulator application. The luge sports case is chosen for its high dynamics to assess the limits of the robot and motion cueing. Though this study uses a pre-recorded set of motion data and runs simulations in non-interactive mode, it aims for real-time interactive simulation for LaRRMoS in the future, so only MCAs capable of real-time operation are inspected. Conducted tests show that the CYL algorithm provides superior performance in highly dynamic motion replication, particularly in lateral accelerations.
Characterisation of Hybrid Photodetector Signals for Satellite Laser Ranging Application
Authors: Salmins K. , Kaulins J. 
Published: July 2024

Abstract
The hybrid photodetector (HPD) is a photomultiplier tube combined with the semiconductor device within the vacuum. The photoelectrons emitted from the photocathode directly hit the semiconductor enabling efficient electron multiplication with low noise and symmetric output pulse. These properties make a hybrid photodetector a good solution for photon-counting applications. At the Satellite Laser Ranging Station of the Institute of Astronomy at the University of Latvia, the hybrid photodetector characteristics were evaluated for SLR applications, including multiphoton mode and time-walk compensation.
Comparative Analysis of Thermal Characteristics: Virgin Polyacrylonitrile (PAN) Versus Electrospun Pan Nanofibre Mats
Authors: Sanchaniya J. V. 
Published: July 2024

Abstract
The utility of polymers in the fabrication of nanofibres via electrospinning is well established. Paramount to their application is understanding of their thermal properties, as these dictate not only their processability but also their mechanical robustness, stability under elevated temperatures, and suitability for intended applications. The electrospinning process, which involves heating polymers and subjecting them to high voltage, inherently modifies their thermal characteristics. This study attempts to elucidate these alterations, particularly by focusing on polyacrylonitrile (PAN) nanofibres. Employing techniques such as thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC), the study compares the thermal properties of electrospun PAN nanofibre mats with those of their virgin counterparts. The PAN nanofibres were synthesised by electrospinning the PAN polymer solution and collecting the resultant mat on a flat plate collector. For a comparative analysis, virgin PAN, from which nanofibres were derived, underwent identical thermal testing. The findings reveal a reduction in the glass transition temperature of PAN nanofibres by approximately 3–5 % compared to virgin PAN. In addition, a significant reduction in heat capacity of about 42 % was observed in the nanofibres. Additionally, the TGA results indicated solvent evaporation at approximately 110 °C. Therefore, this investigation sheds light on the nuanced alterations in the thermal characteristics of PAN nanofibre mats as a result of the electrospinning process, providing vital insights for their application in various thermal management scenarios.
Digital Psychosocial Follow-up for Childhood Critical Illness Survivors: A Qualitative Interview Study on Health Professionals’ Perspectives
Authors: Hagen Marte Hoff , Hartvigsen Gunnar , Jaccheri Letizia , Papavlasopoulou Sofia 
Published: July 2024

Abstract

Background
Digital solutions have been reported to provide positive psychological and social outcomes to childhood critical illness survivors, a group with an increased risk for long-term adverse psychosocial effects.

Objective
To explore health professionals’ perspectives on the potential of digital psychosocial follow-up for childhood critical illness survivors.

Methods
Using a qualitative approach, expert interviews with six health professionals working at a Norwegian hospital were conducted. Transcribed interviews were analyzed using Braun and Clarke’s six-phase thematic analysis framework. Concurrent data collection and analysis using inductive coding was also employed, and a model of codes was constructed.

Results
The interview yielded thirteen unique codes regarding the health professionals’ perspectives on the potential for digital psychosocial follow-up for childhood critical illness survivors, organized in a model comprising the two main themes: Affecting Factors and Digital Usage. Demographic factors (the child’s medical condition, age, gender, and residence) and environmental factors (the child’s family and health professionals) tended to affect the current psychosocial follow-up. Hospital limitations concerning a lack of digital solutions, worse relationship building with video communication, and children’s already high screen time reflected the current state of digital usage. However, ongoing digitalization, existing successful digital solutions, children’s good digital skills, and an ongoing process of creating an artifact are also seen as opportunities for digital usage in future psychosocial follow-up for childhood critical illness survivors.

Conclusions
Researchers can build further on these findings to investigate the potential of digital psychosocial follow-up for childhood critical illness survivors, and clinicians can use it as a starting point for improving psychosocial follow-up.
Die Schuldenbremse – ein Garant für nachhaltige Haushaltspolitik? Eine Replik auf Feld et al. (2024)
Authors: Mühlenweg Leo , Kaczmarczyk Patrick , Hornung Lukas , Kleimeier Nils 
Published: July 2024

Abstract
In the debate on the German debt brake, there is an emerging consensus in favour of reform. Most recently, Feld et al. (2024) attempted to refute the frequently voiced criticism that the debt brake hinders government investment. The synthetic control method used compares Germany’s actual investment activity with a synthetic “Germany without a debt brake”. This article attempts to address the methodological problems of the study by using the augmented synthetic control method, but irrespective of this extension, fundamentally questions the results in Feld et al. (2024).
Förderprogramme für Kommunen: politische Verflechtungen und Informationsdefizite
Authors: Christofzik Désirée I. , Quinckhardt Matthias 
Published: July 2024

Abstract
In financing investments, municipalities rely heavily on infrastructure grants. These funds are distributed through numerous programmes, with the states playing a significant role. Empirical research suggests that political affiliations influence the allocation of these funds. On one hand, political actors on the donor side tend to favour connected municipalities. On the other hand, information asymmetries on the recipient side can explain why certain municipalities receive less funding. Consequently, funds may not end up where they generate the greatest impact. The article synthesises available evidence and derives implications for the design of grant programmes.
Die Tücken der Ungleichheitsmessung: Rezeption einer aktuellen Debatte

Published: July 2024

Abstract
Auten and Splinter (2024) is the latest contribution to an ongoing debate regarding the historical development of income inequality in the U.S. This debate is mainly based on the seminal work of Piketty and co-authors. Auten and Splinters’ results challenge established measurement techniques as their results indicate a much weaker increase in income inequality compared to Piketty and co-authors. This article summarises and discusses major differences between the approaches and the results. However, U.S. results on inequality are only of limited use for similar debates in Germany. This is due to the fact that the inequality debate in Germany focuses more on wealth than income inequality. Additionally, German data infrastructure prohibits any expressive replication of the approaches discussed in this article.
Kritische Rohstoffe: Wie die EU ihre China-Abhängigkeit senken will
Authors: Kuhn Britta 
Published: July 2024

Abstract
By 2030, the EU wants to extract, process and recycle domestically at least 10%, 40% and 25% respectively of the strategic raw materials it consumes. No more than 65% of these rare resources should stem from a single third country. The CRM Act’s benchmarks are primarily to be achieved via financially supported strategic projects. In addition, the EU signed raw materials partnerships with nine countries to date. However, the self-reliance targets for raw materials such as rare earth metals seem unrealistic for technical and environmental reasons. Instead, the EU should enter into more partnerships with likeminded countries.
Bundesbank-Verluste: Bilanzierungspraxis und etwaige Nachschusspflicht des Bundes
Authors: Hansen Arne 
Published: July 2024

Abstract
The Bundesbank’s balance sheet and those of other central banks in the eurozone are currently showing high “operating“ losses due to the discrepancy between the low interest bearing securities holdings from bond purchases and the now higher interest bearing commercial bank deposits. However, the current accounting practice does not reflect the associated losses in value anywhere near the market level – even though, according to the PSPP ruling of the German Federal Constitutional Court, the sale of securities before final maturity should be the rule. Even under the current valuation practice, an equity gap cannot be ruled out in the future, which is generally seen as unproblematic for central banks. However, there are risks in the context of recapitalisation by the state. Within the eurozone, national and European requirements could make such capital injections necessary.

Исследована финансовая устойчивость и вероятность банкротства ПАО «Газпром нефть». Используя представленный авторский интегральный показатель, реально добиться обоснованного обобщения всей оценки финансового состояния. Интегральные показатели оценки вероятности банкротства, обозначили наличие финансового риска, вызванного недостаточностью собственного капитала, но «Газпром нефть» обладает достаточной прочностью для своевременного и полного погашения обязательств, а также из года в год демонстрирует уверенные экономические результаты, способные нивелировать несбалансированность баланса, определяемая нормативными рекомендациям, а не финансово-производственными реалиями.
Investigated financial stability and the likelihood of bankruptcy of PJSC Gazprom Neft. Using the presented author's integral indicator, it is really possible to achieve a justified generalization of the entire assessment of the financial state. The indicator is constructed in such a way that the positive results of the corporation in one area are capable of leveling the negative in another. Integral indicators of the assessment of the probability of bankruptcy, indicated the presence of financial risk caused by the insufficiency of equity, but Gazprom Neft has sufficient strength for timely and full repayment of obligations, and from year to year demonstrates strong economic results that can offset the imbalance in the balance, determined by the regulatory recommendations, but not financial and production realities.
