Abstract
Background Health Services Research (HSR) is a growing field in Germany,
in which Organisational Health Services Research (OHSR) has emerged as a
subfield. The aim of this scoping review was to provide an overview of the field
of OHSR within HSR in Germany and to map systematically original contributions
by describing the organisational setting, the research design, the research
objectives and the theoretical underpinning.
Methods A scoping review examined published abstracts from the 19th German
Conference on Health Services Research 2020. Abstracts were included if (1)
health care organisations, subunits or organisational processes were mentioned
as research objects, and (2) if at least one out of five research perspectives
from a recent German definition of OHSR was addressed. After intensive pilot
screenings within a group of nine researchers, all abstracts were screened
independently in three review teams with three researchers each, and data from
included abstracts were extracted using content analysis based on a
self-developed detailed coding scheme.
Results Out of n=468 identified abstracts in German (84%) or English (16%)
language, n=138 (29.5%) abstracts were included. The majority of included
abstracts addressed acute care in hospitals (34.8%), reported results from
observational studies (59.4%) and collected primary data (69.6%). There was a
slightly higher use of quantitative (32.6%) than qualitative (24.6%) research
methods with a considerable number of studies using more than one method
(31.9%). An explicit reference to theory was made in 7.2% and 17.4% used the
term ‘organisation’ or related terms explicitly in their abstract.
Conclusion This review provides a systematic but preliminary overview of
the scope to which HSR in Germany addresses OHSR. The organisational perspective
is considered extensively in HSR abstracts, but mostly implicitly. The research
is reported largely free of theory which can reduce their explanatory power.
Therefore, a research agenda, more awareness as well as education and better
conceptualisation of OHSR topics within German HSR are needed.
Late-Onset Concurrent Infection of Vaccine Strain VZV and HSV-1 after Varicella Vaccination in a Child with Natural killer T Cell Deficiency

Published: June 2024

AbstractWe describe a case with natural killer cell deficiency of late-onset Oka vaccine varicella zoster virus (VZV) strain and Herpes simplex virus-1 (HSV-1) dual infection resulting in fatal clinical course. An 18-month-old boy presented with a papulovesicular rash, mucocutaneous candidiasis, encephalopathy, and severe respiratory distress 6 months after receiving varicella vaccine. VZV and HSV-1 were analysed by real-time reverse-transcriptase polymerase chain reaction (RT-qPCR) and Oka vaccine strain of VZV by gene sequencing. HSV-1 and VZV dual infection was detected in the blood and skin samples by RT-qPCR. Gene sequencing of VZV isolated from vesicular lesions was compatible with the Oka vaccine strain. Flow cytometry revealed a natural killer deficiency, but whole exome analysis failed to identify an associated genetic defect. Vesicular rashes in immunocompromised patients who were inadvertently vaccinated should be taken seriously, and antiviral therapy should be prompt and aggressive.
Strong electron–phonon coupling and multigap superconductivity in 2H/1T Janus MoSLi monolayer

Published: June 2024

Two-dimensional (2D) Janus transition metal dichalcogenides MXY manifest novel physical properties owing to the breaking of out-of-plane mirror symmetry. Recently, the 2H phase of MoSH has been demonstrated to possess intrinsic superconductivity, whereas the 1T phase exhibits a charge density waves state. In this paper, we have systematically studied the stability and electron–phonon interaction characteristics of MoSLi. Our results have shown that both the 2H and 1T phases of MoSLi are stable, as indicated by the phonon spectrum and the ab initio molecular dynamics. However, the 1T phase exhibits an electron–phonon coupling constant that is twice as large as that of the 2H phase. In contrast to MoSH, the 1T phase of MoSLi exhibits intrinsic superconductivity. By employing the ab initio anisotropic Migdal-Eliashberg formalism, we have revealed the two-gap superconducting nature of 1T-MoSLi, with a transition temperature (Tc) of 14.8 K. The detailed analysis indicates that the superconductivity in 1T-MoSLi primarily originates from the interplay between the vibration of the phonon modes in the low-frequency region and the dz2 orbital. These findings provide a fresh perspective on superconductivity within Janus structures.

Abstract
This paper provides a preliminary description of the comparative construction in Tujia1 (northern dialect; NT), an endangered ergative Tibeto-Burman (TB) language spoken in China, in the context
of the typologically diverse ways in which comparative meaning is expressed. In mono-clauses in NT, comparative marking depends on
the position of the standard (i.e., that which is compared to). The standard may be marked with an ablative marker, or a topic
marker if it appears in sentence-initial position due to left dislocation; otherwise, the comparandum (i.e., that which is to be
compared) is assigned an ergative marker. Ergative on the comparandum and ablative on the standard can both occur but this is not
obligatory. We propose that the ablative is the primary comparative marker in NT. However, this construction is subject to
variation: the ablative marker is being replaced by a topic marker on the standard or by an ergative marker on the comparandum. We
analyze this as change in progress (partly as a result of language contact); specifically, we propose that an ergative marker on
the comparandum is starting to function as a focus marker, and in which the comparative meaning is derived from reanalysis. On the
other hand, the comparative meaning in constructions where the standard is marked with a topic marker is proposed to result from
the functional extension of the topic structure to comparative constructions. Both ergative marking on the comparandum and topic
marking on the standard are typologically rare. Thus, the analysis of comparison marking in Tujia contributes to the typological
understanding of comparative constructions in general.
Competence-in-performance in China’s ESL teaching
Authors: Guo Yijing 
Published: June 2024

Abstract
This paper endeavours to explain why Weigand’s dialogic theory – the Mixed Game of human
competence-in-performance – should be considered in improving Chinese College English language teaching. This paper will review
several of Weigand’s key publications and research and analyse current Chinese College English language textbooks and teachers’
attitudes toward teaching English speaking. The results suggest that teachers refuse to be involved in teaching English speaking
because they lack adequate training and need a theory to guide them. Therefore, based on Weigand’s theory of human
competence-in-performance, the paper proposes several suggestions for improving oral English teaching. This article hopes to
contribute to the further study of dialogic pragmatics in Chinese English language-speaking teaching.
football club is family
Authors: Theodoropoulou Maria 
Published: June 2024

Abstract
This is a corpus-based study with data from football fans’ comments on Facebook, which seeks to explore the
contribution of metaphor to the construction of collective identity. The main question it addresses is the following: in as much
as collectivity is constructed by typical means, e.g., the use of the first person plural and analogous expressions, what is it
that a metaphor attributes to an already constructed collectivity? Furthermore, as the shared love of the team is considered to be
the basis of a football fans’ group formation, this study also explores the role of emotion in the emergence of metaphor.
Cross-scale mechanobiological regulation of cylindrical compressible liquid inclusion via coating
Authors: Ti Fei , Yu Chenlei , Li Moxiao , Liu Shaobao , Lu Tian Jian , Chen Xin 
Published: June 2024

AbstractThe double-bag theory in modern anatomy suggests that structures with coatings are commonly found in human body at various length scales, such as osteocyte processes covered by pericellular matrix and bones covered by muscle tissue. To understand the mechanical behaviors and physiological responses of such biological structures, we develop an analytical model to quantify surface effects on the deformation of a coated cylindrical compressible liquid inclusion in an elastic matrix subjected to remote loading. Our analytical solution reveals that coating can either amplify or attenuate the volumetric strain of the inclusion, depending on the relative elastic moduli of inclusion, coating, and matrix. For illustration, we utilize this solution to explore amplification/attenuation of volumetric strain in musculoskeletal systems, nerve cells, and vascular tissues. We demonstrate that coating often plays a crucial role in mechanical regulation of the development and repair of human tissues and cells. Our model provides qualitative analysis of cross-scale mechanical response of coated liquid inclusions, helpful for constructing mechanical microenvironment of cells.
Dye-sensitized solar cells based on anatase- and brookite-TiO2: enhancing performance through optimization of phase composition, morphology and device architecture
Authors: Khazaei Mobina , Mohammadi M R , Li Yuning 
Published: June 2024

Abstract
Herein, we demonstrate an optimization of dye-sensitized solar cells (DSSCs) through the development of single-layer and double-layer configurations. Focusing on the incorporation of brookite and anatase phases in varying ratios, the study aims to determine the optimal composition for enhanced photovoltaic performance. The active layer, composed of anatase- and brookite-TiO2 nanoparticles, is further modified with a scattering layer comprising a mixture of anatase nanoparticles and brookite-TiO2 in the form of nanocube or rice-like particles. The synthesis of TiO2 nanostructures with various morphologies and phase compositions and their subsequent application in single-layer and double-layer DSSCs are presented. The results highlight the superior light-harvesting capabilities achieved through the strategic incorporation of brookite phase into the anatase phase, emphasizing the importance of optimizing the anatase: brookite ratio. The single-layer DSSCs exhibit a peak efficiency of 8.73%, achieved with a composition of 30 wt.% brookite and 70 wt.% anatase at a thickness of 15 μms. In the context of double-layer DSSCs, the combined optimization of the active layer composition, scattering layer morphology, and utilization of anatase nanoparticles leads to a remarkable efficiency of 9.18%. These findings underscore the critical role of composition and morphology in enhancing the performance of DSSCs, showcasing the potential for brookite-based DSSCs in solar energy conversion.
Limits of the harmonic approach for the Morse potential
Authors: Perá Leonan Augusto Massete , Stella Guilherme Barbosa , Campos José Renato , da Silva Josimar Fernando 
Published: June 2024

Abstract
This paper presents the solution of the Morse potential via the Variational Method using a trial eigenfunction based on the harmonic oscillator and without variational parameters. The first fundamental state and the first nine excited states for the diatomic molecules of hydrogen, lithium hydride, sodium hydride, oxygen, carbon monoxide and silicon monoxide are calculated. The results obtained by the variational method are compared with the values obtained by the exact solution of the same potential in order to establish a percentage error for each energy level of the molecules analyzed and to verify up to which level the chosen trial eigenfunction describes the original system well. That shows that the approximation of the trial eigenfunction is reasonable for the first excited states. From the fourth or fifth excited state, depending on the molecule, the discrepancy no longer reasonable.
Vector wave dark matter and terrestrial quantum sensors
Authors: Amaral Dorian W.P. , Jain Mudit , Amin Mustafa A. , Tunnell Christopher 
Published: June 2024

Abstract(Ultra)light spin-1 particles — dark photons — can constitute all of dark matter (DM) and have beyond Standard Model couplings. This can lead to a coherent, oscillatory signature in terrestrial detectors that depends on the coupling strength. We provide a signal analysis and statistical framework for inferring the properties of such DM by taking into account (i) the stochastic and (ii) the vector nature of the underlying field, along with (iii) the effects due to the Earth's rotation. Owing to equipartition, on time scales shorter than the coherence time the DM field vector typically traces out a fixed ellipse. Taking this ellipse and the rotation of the Earth into account, we highlight a distinctive three-peak signal in Fourier space that can be used to constrain DM coupling strengths. Accounting for all three peaks, we derive latitude-independent constraints on such DM couplings, unlike those stemming from single-peak studies. We apply our framework to the search for ultralightB - LDM using optomechanical sensors, demonstrating the ability to delve into previously unprobed regions of this DM candidate's parameter space.
Identifying Three New AGNs among Fermi Unidentified Gigaelectronvolt Sources
Authors: Ji Shun-Hao , Wang Zhong-Xiang , Huang Qiang-Meng , Yang Ruo-Heng 
Published: June 2024

Abstract
We report our identification of three gigaelectronvolt γ-ray sources, 4FGL J0502.6+0036, 4FGL J1055.9+6507, and 4FGL J1708.2+5519, as Active Galactic Nuclei (AGNs). They are listed in the latest Fermi-Large Area Telescope source catalog as unidentified ones. We find that the sources all showed γ-ray flux variations in recent years. Using different survey catalogs, we are able to find a radio source within the error circle of each source’s position. Further analysis of optical sources in the fields allows us to determine the optical counterparts, which showed similar variation patterns to those seen in γ-rays. The optical counterparts have reported redshifts of 0.6, 1.5, and 2.3, respectively, estimated from photometric measurements. In addition, we also obtain an X-ray spectrum of 4FGL J0502.6+0036 and a flux upper limit on the X-ray emission of 4FGL J1055.9+6507 by analyzing the archival data. The broadband spectral energy distributions of the three sources from radio to γ-rays are constructed. Comparing mainly the γ-ray properties of the three sources with those of different sub-classes of AGNs, we tentatively identify them as blazars. Followup optical spectroscopy is highly warranted for obtaining their spectral features and thus verifying the identification.

Published: June 2024

Abstract
The International Celestial Reference Frame (ICRF) plays an important role in astronomy and geodesy. The realization of ICRF is based on the position of thousands of quasars observed using the Very-Long Baseline Interferometry (VLBI) technique. Better quality of ICRF is achieved when the position of the quasars is stable. In this study, we aim to analyze the stability of one of the quasars in ICRF called 4C31.61 (2201+315). We performed VLBI data analysis by using Vienna VLBI and Satellite Software (VieVS) to get the position of the quasar. We also used the data of the quasar’s position from the Paris Observatory Geodetic VLBI Center. We examined the stability of the quasar position by using the Allan standard deviation technique. We found that the quasar 4C31.61 (2201+315) has a stable position with the dominance of white noise across the majority of time scales.

Published: June 2024

Abstract
The circular restricted three body problem (CRTBP) is a well-known problem that has a very important contribution to understand the dynamics of celestial objects, including the binary stars and planetary system. In this study, we extend the classical version of CRTBP by assuming both primaries emit radiation and have oblate shape. We also consider the potential from a disk like structure that surrounds this three-body system. The stability of the infinitesimal body is investigated by using Lyapunov Exponent Indicators (LEI). First, we have done a numerical survey by testing several initial locations of the infinitesimal body that have chaotic or regular orbital behaviour. Second, we estimated the stability of triangular equilibrium points and show that the equilibrium points are conditionally stable with respect to the critical mass parameter (μc
). We found that the determined μc
from LEI method match μc
from linear stability analysis.

Published: June 2024

Abstract
In this paper, we revisited the model of gravitational potential generated by irregular shapes. A finite straight segment model was used to investigate the motion of particles around a massive straight segment of length 2l, mass M, and uniformly rotates with angular velocity ω. We extended this model by converting it to the cylindrical coordinate and applied this model to the asteroid (338) Budrosa. We obtained the position of equilibrium points in this system. We also estimate the zero-velocity curve and determine the Poincare map and its periodic orbit around equilibrium points.

Published: June 2024

Abstract
Light pollution contributes to sustainability issues in urban areas. Raising awareness regarding light pollution and its effects becomes a necessity to increase individual contribution in reducing light pollution. We chose light pollution as a topic for collaborative courses in our university to facilitate collaboration between courses’ participants in promoting awareness regarding light pollution to the public. The participants were required to work in groups to explore light pollution issues. They also collected light pollution data using a citizen science project. They were also required to design visual media and plan a public event to promote public awareness. Students’ surveys were collected to assess the benefits of this collaborative project and as part of evaluation tools. The impact of the project to the society will be measured in the future since more data are needed.

Published: June 2024

Abstract
This paper describes a method of simulating the ultrasonic longitudinal wave (P-wave) propagation in titanium alloy. The two-dimensional geometric model of polycrystalline titanium alloy is established using the Voronoi algorithm. Then, the model was imported into COMSOL software for grid division and parameter setting. The continuous observation of P-wave propagation was realized after adding the physical field of sound pressure and the boundary condition. Further, the first and second transmitted P-wave obtained the ultrasonic attenuation spectrum (UAS). The inverse method determines the average grain size (AGS) by fitting the UAS. It was found that the AGS

Published: June 2024

Abstract
In this paper, the iron-based amorphous/AZ31 microlaminated composites with multilayer structures were successfully prepared by using the vacuum hot-pressing method. The microstructure and chemical element distribution were analyzed, and the mechanical properties and microhardness were tested. Research findings revealed that a thin iron-aluminum intermetallic compound layer was formed between the iron-based amorphous alloy and AZ31, and the interlayers were tightly bonded. The microhardness of the amorphous after the hot-pressing reaction reached 1590 HV and there was a hardness gradient between the AZ31 layer and the amorphous layer. The bending strength reached 516 MPa after hot-pressing temperature at 520°C and the impact toughness was about 6 J/cm2. The fracture behavior was a combination of brittle fracture and ductile fracture. The microstructure and the properties of the laminated composites can be designed by adjusting the process according to the performance needs, which opens up broad prospects for the wide application of amorphous alloys.

Published: June 2024

Abstract
Shape memory alloy (SMA) is widely used in the field of soft robots due to its high energy density and favorable load-to-weight ratio. However, the cooling time of SMA wire in the soft matrix is relatively long, limiting its response velocity. In this study, we develop a fast-response SMA artificial muscle (FSAM), which accelerates the cooling rate of SMA wire through the active heat absorption of the thermoelectric module and the evaporation/dehydration of hydrogel. The hydrogel also facilitates the heat dissipation of the thermoelectric module. Additionally, COMSOL is utilized to investigate the thermal characteristics of the SMA wire under different conditions. The simulation results demonstrate that the cooling rate of the SMA wire increases significantly with the proposed heat dissipation scheme.

Authors: Zhao Liangliang , Zhang Rui , Zhang Hua , Ma Jia , Du Yupei , Hu Zhenyu 
Published: June 2024

Abstract
Addressing the limitations of traditional lunar exploration mesh wheels in improving the traction performance of unmanned lunar rovers through conventional optimization, this study introduces a novel bionic mesh wheel design inspired by the characteristics of ostrich toes. A comparative wheel design is also developed for control experiments. Discrete element simulations are conducted for both the bionic and comparative wheels. Comparative analysis of their macroscopic simulation data reveals that the bionic wheel outperforms the comparative wheel in terms of traction performance. Furthermore, the bionic wheel exhibits higher traction efficiency and energy savings at lower slip ratios. The feasibility of the proposed design is validated through soil trough experiments, providing evidence for its practical viability in enhancing the traction capabilities of unmanned lunar exploration vehicles.
