Published: February 2023

SummaryFunktionelle Herzrhythmusstörungen sind kardiologisch nicht behandlungsbedürftig, schränken aber oftmals die Lebensqualität ein und weisen auf diverse mögliche Dysfunktionen hin, die sich osteopathisch gut behandeln lassen. Insbesondere die Ipsilateralität und Symmetrie der vegetativen Herzinnervation sowie die Regulation und Funktion anatomischer Strukturen wie Foramen jugulare, 1.–5. Rippe, Herzligamente oder Ductus lymphaticus spielen für den Herz-rhythmus eine zentrale Rolle. Im vorgestellten Fall konnten subjektive Extrasystolen, Herzklopfen, Arrhythmie und Schwindelgefühl unter anderem über Muskel-Energie-, Manipulations-, Mobilisations-, Ligament-, Disengagement, Triggerpunkt-, Rib-Raising-, Detonisierungs- und Release-Techniken erfolgreich behandelt werden.

AbstractTechnological pedagogical content knowledge (TPACK) has evolved as a valuable model for understanding teacher performances in technology use in education to support pedagogy with proper content knowledge for the success of teaching and learning. Many self-report questionnaires have been developed for TPACK. However, limited studies assessed the extension of the questionnaires for a specific context. This study aims to develop and validate a questionnaire scale to assess elementary school teachers’ TPACK and the Use of the Internet (UotI). We used the scale to report TPACK’s internal relationships and TPACK with UotI. The study measured whether the model reflects transformative perspectives concerning how the domains (TPACK and UotI) interact. The initial scale consisted of 43 items, validated and assessed for reliability through some procedures; face and content validity, pilot study, and measurement model in the partial least-square structural equation modeling (PLS-SEM). The scale was distributed to 1100 elementary school teachers. Findings inform that 40 scale items are valid and reliable for assessing teachers’ TPACK and UotI. The significant relationships of all factors support a transformative view of the scale.
The role of the Internet in later life autonomy: Silver surfers in Spain
Authors: Llorente-Barroso Carmen , Sánchez-Valle María , Viñarás-Abad Mónica 
Published: February 2023

AbstractThe new digital panorama has enhanced the importance of the Internet, as well as Information and Communications Technology (ICT), in developing a society in which seniors play a proactive role. The main purpose of this article is to define a taxonomy of silver surfers according to the ways they use the Internet and ICT, with a special focus on e-commerce and e-government. A quantitative methodology was used, based on the study of 405 Spanish internet users between 60 and 79 years of age, which was conducted by telephone in February of 2019. Seven groups were identified through a combination of dimensionality reduction techniques and cluster analysis. The results indicate neither a consistent pattern in the specific ways older adults use the Internet nor a homogeneous level of digital knowledge among this demographic group. To some extent, this is a result of disparities in both the perception of digital security that seniors associate with e-commerce and/or e-government and the level of trust engendered by such operations. The Able and Daring are the most numerous clusters, which coincide with the categories of the most active and prepared users. The Sceptical take third place in terms of number of users, as they display limited use of the Internet and claim to have a low digital skills level. However, carrying out both online shopping and administrative procedures without the need for assistance is becoming increasingly frequent among all of those surveyed.

Authors: Ortega-Sánchez Delfín , López-Sanvicente Amparo Bernal 
Published: February 2023

AbstractThe present study, on the one hand, seeks to offer the validated design of the Digitization of Cultural Heritage, Identities and Education (DICHIE) instrument, applicable in focus-group contexts, to extract qualitative data on both the needs and the challenges relating to the digitization of the cultural heritage of Castile and Leon (Spain). On the other hand, it aims to facilitate the contribution of solutions within the field of education and cultural policy for the cultural heritage within this Autonomous Community. The research adheres to quantitative-descriptive methodological principles and, in particular, follows instrumental psychometric studies of reliability and content validity. The results of the instrument were optimal, both in terms of internal reliability and complete global and intra-group content validity, for its application to professional areas of heritage conservation and education and digital cultural management.
Correlation between protein conformations and water structure and thermodynamics at high pressure: A molecular dynamics study of the Bovine Pancreatic Trypsin Inhibitor (BPTI) protein
Authors: Roy Umesh C. , Bandyopadhyay Pradipta 
Published: February 2023

Pressure-induced perturbation of a protein structure leading to its folding–unfolding mechanism is an important yet not fully understood phenomenon. The key point here is the role of water and its coupling with protein conformations as a function of pressure. In the current work, using extensive molecular dynamics simulation at 298 K, we systematically examine the coupling between protein conformations and water structures of pressures of 0.001, 5, 10, 15, 20 kbar, starting from (partially) unfolded structures of the protein Bovine Pancreatic Trypsin Inhibitor (BPTI). We also calculate localized thermodynamics at those pressures as a function of protein–water distance. Our findings show that both protein-specific and generic effects of pressure are operating. In particular, we found that (1) the amount of increase in water density near the protein depends on the protein structural heterogeneity; (2) the intra-protein hydrogen bond decreases with pressure, while the water–water hydrogen bond per water in the first solvation shell (FSS) increases; protein–water hydrogen bonds also found to increase with pressure, (3) with pressure hydrogen bonds of waters in the FSS getting twisted; and (4) water’s tetrahedrality in the FSS decreases with pressure, but it is dependent on the local environment. Thermodynamically, at higher pressure, the structural perturbation of BPTI is due to the pressure–volume work, while the entropy decreases with the increase of pressure due to the higher translational and rotational rigidity of waters in the FSS. The local and subtle effects of pressure, found in this work, are likely to be typical of pressure-induced protein structure perturbation.

Published: February 2023

Charge transport is one of the key factors in the operation of organic solar cells. Here, we investigate the electron and hole transport in the non-fullerene acceptor (NFA) IT-4F, by a combination of space-charge-limited current measurements and multiscale molecular simulations. The electron and hole mobilities are fairly balanced, amounting to 2.9 × 10−4 cm2 V−1 s−1 for electrons and 2.0 × 10−5 cm2 V−1 s−1 for holes. Orientational ordering and electronic couplings facilitate a better charge-percolating network for electrons than for holes, while ambipolarity itself is due to sufficiently high electron affinity and low ionization energy typical for narrow-gap NFAs. Our findings provide a molecular-level understanding of the balanced hole and electron transport in an archetypical NFA, which may play a key role in exciton diffusion and photogenerated hole transfer in organic solar cells.
Molecular phylogeny, systematics and biogeography of the subfamily Nemognathinae (Coleoptera, Meloidae)
Authors: Riccieri Alessandra , Capogna Emilia , Pinto John D. , Bologna Marco A. 
Published: February 2023

Nemognathinae is the most widespread subfamily of Meloidae, with ~600 species, and includes the only blister beetles distributed in Australia and on islands of the western Pacific. Four tribes are recognised based on morphology: Stenoderini, Palaestrini, Horiini and Nemognathini. Using two mitochondrial (16S, COI) and three nuclear markers (CAD, 28S, ITS2), and both maximum likelihood and Bayesian approaches, this study describes the evolutionary history of Nemognathinae based on molecular data for the first time. We provided a fossil-calibrated phylogeny that unravels the phylogenetic relationships among the tribes and among most of the genera, and a reconstruction of the biogeographic history using a parametric approach. Our results recognised the four tribes that were described previously based on morphology and revealed the presence of another well-differentiated clade corresponding to the genus Zoltanzonitis. Phylogenetic relationships among the tribes are well supported, with Stenoderini as the most ancient lineage, followed by Zoltanzonitini, Palaestrini, Horiini and Nemognathini. A few long-standing genera within Nemognathini (Nemognatha, Zonitis, Stenoria) and the nominate subgenus Stenodera (Stenodera) were recovered as polyphyletic. In addition, biogeographic analyses revealed the origin of the subfamily in the Old World during the Eocene, and the associated diversification into the five tribes astride the Eocene and Oligocene between 46 and 30 Ma. Based on these results we propose the new tribe Zoltanzonitini, and the elevation of the subgenus Pronemognatha to genus level, new status. In addition, Zonitoschema breveapicalis new comb., Z. curticeps new comb. and Z. pulchella new status are proposed. ZooBank: urn:lsid:zoobank.org:pub:72EECC6D-36A6-4DD7-B4DB-D0692034E775.
Necessity modal development in Singapore English
Authors: Basile Carmelo Alessandro 
Published: February 2023

AbstractSpoken in a multilingual environment characterised by continuous contacts with other languages, Singapore English (SgE) is a singular object of study. Its modal system has also been developing in independent ways compared to inner-circle varieties, e.g. British English, its historical ancestor. Different approaches have attempted to explain such developments, including the substratist and the grammaticalisation approaches. The present paper explores both these approaches with the aim of examining the role that they may have in the development of the (semi-)modal verbs of necessity in SgE. Using some corpus analysis conducted on informal data, it will be shown why the substratist approach does not seem sufficient to explain the relatively frequent non-epistemic uses ofmustin SgE. It will be discussed how SgEmustcould be instead replicating older dynamic uses, typical of Middle English times (1100–1500 CE), according to a process known as replica grammaticalisation as recapitulation (Ziegeler 2014).
How can we communicate (visually) what we (usually) mean by collocation and keyness?
Authors: Jeaco Stephen 
Published: February 2023

Abstract
Corpus linguistic methods can now be easily employed in a wide range of studies within sub-disciplines of
linguistics and well beyond. In a two-part paper, Gries (2022a, 2022b) challenges some of the most widely used ‘association measures’ of what many might feel to be
powerful aspects of text patterning: collocation and key words. While the additional association measure offers some new
possibilities, this paper highlights the strong influence of another frequency parameter on odds ratio and Gries’s suggested
association measure, and questions the applicability of his cautions for many different kinds of corpus research. Nevertheless,
having been inspired to look at different aspects of association and dispersion more carefully, the author presents some new
visualizations which were designed to communicate some of the important lessons to be learned from Gries’s papers, especially for
learners and teachers using corpus tools in Second Language classrooms.

ABSTRACTSubstantial evidence links physical activity and sedentary behaviour (SB) with cardiovascular health. However, studies usually examine time‐use behaviours independently, rather than considering daily activities as a 24‐hour time‐use composition. This study aimed to use compositional data models to investigate how time reallocations from SB to moderate‐to‐vigorous physical activity (MVPA)/ light physical activity (LPA) were associated with changes in cardiometabolic biomarkers. Compositional isotemporal substitution analysis was conducted using data from a representative cross‐sectional sample of adults aged 20 years or older (n = 5213 full sample; n = 2221 fasting subsample) from the 2003–2004 and 2005–2006 cycles of the National Health and Nutrition Examination Survey. Overall as well as gender‐ and age‐specific estimates were obtained for reallocating time between the behaviours associated with cardiometabolic outcomes. Replacing SB with MVPA was associated with decreased levels of C‐reactive protein (CRP), white blood cells (WBCs), red blood cell distribution width (RDW), insulin, insulin resistance homeostasis model assessment (HOMA‐IR) and 2‐hour glucose, and increased high‐density lipoprotein cholesterol (HDL‐C), except for WBCs in older adults, insulin and HOMA‐IR in females and older adults, 2‐hour glucose in young and older adults, and HDL‐C in older adults. Substituting LPA for SB resulted in lower CRP in older adults, lower RDW in males and older adults, lower insulin in young and middle‐aged adults, lower HOMA‐IR in females and middle‐aged adults, and higher HDL‐C in males and young adults. Our findings provide new evidence for the potential benefits of LPA and MVPA in cardiovascular health and help make population‐specific recommendations for physical activity.Highlights

Shorter sedentary behaviour (SB) time and longer active behaviours time are associated with a lower cardiovascular disease risk profile.
Although replacing SB with MVPA has stronger positive health effects, LPA, as a simpler and more feasible activity, may has greater potential in promoting cardiovascular health.
The expected changes in cardiometabolic biomarkers caused by time reallocations from SB to MVPA/LPA vary with gender and age, and physical activity guidelines with specific recommendations should be tailed to the subpopulations.

Abstract
We measured the angular distribution of the subsequently emitted Lyman-α
1 transition of Xe53+* ions following nonradiative electron capture in collisions of 197 MeV u−1 Xe54+ projectiles with gaseous krypton target. The alignment of the projectile 2p
3/2 state and the relative population of its magnetic substates were further deduced. In contrast to the available lower energy results (Yang et al 2020 Phys. Rev. A 102 042803), it is found that at 197 MeV u−1 the Lyman-α
1 radiation becomes much less anisotropic and the magnetic substates are nearly statistically populated. Moreover, the experimental findings are compared with the results of the corresponding radiative electron capture mechanism, obviously different energy dependence of the magnetic-substate population is obtained and discussed using semiclassical arguments, which help reveal the population mechanism of excited states in collisions of highly charged high-Z ions with atoms.

Published: February 2023

Abstract
A simple, cost-effective and high-accuracy measurement of parallelism by dual-autocollimators is proposed. A differential measurement was chosen to eliminate most of the environmental noises and systematic errors. The accuracy of parallelism measurement can reach the level of 1.6 μrad (1σ). This method can be widely used for parallelism measurements of components with reflective coating, such as glass blocks in metrology laboratories and test masses in the gravitational reference sensor.

Abstract
Damage to bridges can result in partial or complete structural failures, with fatal consequences. Cracks develop in concrete infrastructure from fatigue loading, vibrations, corrosion, or unforeseen structural displacement. Effective long-term monitoring of civil infrastructure can reduce the risk of structural failures and potentially reduce the cost and frequency of inspections. However, deploying structural health monitoring technologies for crack detection on bridges is expensive, especially long-term, due to the density of sensors required to detect, localize, and quantify cracks. Previous research on soft elastomeric capacitors (SECs) has shown their viability for low-cost monitoring of cracks in transportation infrastructure. However, when deployed on concrete for strain monitoring, a structure/sensor capacitive coupling exists that may cause a significant amplification in the signal collected from the SEC sensor. This work provides a detailed experimental study of electrically isolating capacitive sensing skins for concrete structures to reduce the structure/sensor capacitive coupling of an electrically grounded sensor. The study illustrates that the use of rubber isolators effectively decreases the capacitive coupling between concrete, which inherently has capacitive properties, and sensors such as the SEC that utilize capacitance measurements. In addition, the required thickness of isolation for accurate strain monitoring using the SEC with geometry described in the paper is investigated and better strain correlation is observed between the rubber of isolation thickness 0.30 mm and 0.64 mm with rubber of isolation of approximately 0.40 mm having the best response. Tests were conducted on small-scale concrete beams, and results were validated on full-scale reinforced concrete bridge decks recently taken out of service. This study demonstrates that with proper isolation material, the SEC can accurately transduce strain from concrete within a 10

Published: February 2023

Abstract
Successful construction of heterojunction can improve the utilization efficiency of solar light by broadening the absorption range, facilitating charge-carrier separation, promoting carrier transportation and influencing surface-interface reaction. Herein, visible-light-driven AgBr was deposited on the surface of lamellar BiVO4 which was prepared by a facile hydrothermal process to improve charge carrier separation, and subsequent photocatalytic effectiveness. The catalyst with an optimal AgBr/BiVO4 ratio exhibited a superbly enhanced photocatalytic decolorization ability (about 6.85 times higher than that of pure BiVO4) and high stability after four cycles. The unique photocatalytic mechanism of S-scheme carrier migration was investigated on the bases of radical trapping tests and photo/electrochemical characterizations. Results showed that the enhanced migration strategy and intimately interfacial collaboration guaranteed the effective charge carriers separation/transfer, leading to magnificent photocatalytic performance as well as excellent stability.

Published: February 2023

Abstract
Proposed resonator design and measurement technique is a promising solution to estimate the value of materials surface conductivity. In the developed device, there are no mechanical connections, that interrupt the flowing microwave currents, which eliminates losses due to poor metal contact and related measurement errors. The main losses (60%) in the resonator are concentrated in a small sample under study - resonance element sample, which ensures high sensitivity to changes in surface conductivity. The influence of annealing the copper cavity resonator surface conducting microwave currents, as well as the effect of graphene coating on its intrinsic quality factor and frequency, was experimentally studied. Technological procedures for modifying a copper surface such as annealing in an H2/Ar atmosphere at a temperature of 1070 °C and subsequent coating with graphene by chemical vapor deposition method are studied. The modification of copper resonator surface texture during heat treatment in hydrogen and argon atmospheres has been studied. It is shown that during annealing, the resonator quality factor increases. The increase of the quality factor was associated with a decrease of resistance of copper, with the growth of crystalline grains, this effect disappears when the resonator is exposed to an air atmosphere. It was found that the graphene coating does not make a significant contribution to the change in the quality factor, but prevents the active growth of the oxide layer and prevents impurities deposition on the copper surface from the atmosphere. Thus, after annealing in hydrogen atmosphere and subsequent coating with graphene, the increased quality factor is retained. The considered procedures can be used to increase and stabilize the resonators quality factor, to eliminate oxidation and contamination of their surface. The results of this work can be used in the designing of microwave devices to study the thin films surface impedance.
