Authors: Widhalm Klaus , Durstberger Sebastian , Greisberger Andrea , Wolf Brigitte , Putz Peter 
Published: January 2024

AbstractIn gait analysis, knowledge on validity and reliability of instruments and influences caused by the examiner’s performance is of crucial interest. These measurement properties are not yet known for commonly used, low-cost two-dimensional (2D) video-based systems. The purpose of this study was to assess the concurrent validity of a video-based 2D system against a three-dimensional (3D) reference standard, as well as the inter-rater reliability, and test–retest reliability of 3D marker application. Level walking was captured simultaneously by a 2D and a 3D system. Reflective markers were applied independently by three raters and repeated by one rater on a second day. We assessed the agreement between the two systems, as well as reproducibility, and inter-rater agreement of derived spatio-temporal parameters and sagittal kinematics. Nineteen healthy participants completed this study. 2D gait analysis provides a possibility to accurately assess parameters such as stride time, stride length, gait velocity, and knee RoM. Interrater and test–retest reliability of 3D gait analysis are generally acceptable, except for the parameters toe-off and pelvic RoM. This is the first study to publish measurement properties of a commercially available 2D video-based gait analysis system, which can support interpretation of gait pattern near the sagittal plane.
Adaptive rewiring shapes structure and stability in a three-guild herbivore-plant-pollinator network
Authors: Su Min , Ma Qi , Hui Cang 
Published: January 2024

AbstractAnimal species, encompassing both pollinators and herbivores, exhibit a preference for plants based on optimal foraging theory. Understanding the intricacies of these adaptive plant-animal interactions in the context of community assembly poses a main challenge in ecology. This study delves into the impact of adaptive interaction rewiring between species belonging to different guilds on the structure and stability of a 3-guild ecological network, incorporating both mutualistic and antagonistic interactions. Our findings reveal that adaptive rewiring results in sub-networks becoming more nested and compartmentalized. Furthermore, the rewiring of interactions uncovers a positive correlation between a plant’s generalism concerning both pollinators and herbivores. Additionally, there is a positive correlation between a plant’s degree centrality and its energy budget. Although network stability does not exhibit a clear relationship with non-random structures, it is primarily influenced by the balance of multiple interaction strengths. In summary, our results underscore the significance of adaptive interaction rewiring in shaping the structure of 3-guild networks. They emphasize the importance of considering the balance of multiple interactions for the stability of adaptive networks, providing valuable insights into the complex dynamics of ecological communities.
Implications of stress-induced gene expression for hematopoietic stem cell aging studies
Authors: Konturek-Ciesla Anna , Olofzon Rasmus , Kharazi Shabnam , Bryder David 
Published: January 2024

AbstractA decline in hematopoietic stem cell (HSC) function is believed to underlie hematological shortcomings with age; however, a comprehensive molecular understanding of these changes is currently lacking. Here we provide evidence that a transcriptional signature reported in several previous studies on HSC aging is linked to stress-induced changes in gene expression rather than aging. Our findings have strong implications for the design and interpretation of HSC aging studies.

AbstractThe E. coli Paraquat Inducible (Pqi) Pathway is a putative Gram-negative phospholipid transport system. The pathway comprises three components: an integral inner membrane protein (PqiA), a periplasmic spanning MCE family protein (PqiB) and an outer membrane lipoprotein (PqiC). Interactions between all complex components, including stoichiometry, remain uncharacterised; nevertheless, once assembled into their quaternary complex, the trio of Pqi proteins are anticipated to provide a continuous channel between the inner and outer membranes of diderms. Here, we present X-ray structures of both the native and a truncated, soluble construct of the PqiC lipoprotein, providing insight into its biological assembly, and utilise neutron reflectometry to characterise the nature of the PqiB-PqiC-membrane interaction. Finally, we employ phenotypic complementation assays to probe specific PqiC residues, which imply the interaction between PqiB and PqiC is less intimate than previously anticipated.

AbstractMany physiological osteocalcin-regulated functions are affected in adult offspring of mothers experiencing unhealthy pregnancy. Furthermore, osteocalcin signaling during gestation influences cognition and adrenal steroidogenesis in adult mice. Together these observations suggest that osteocalcin may broadly function during pregnancy to determine organismal homeostasis in adult mammals. To test this hypothesis, we analyzed in unchallenged wildtype and Osteocalcin-deficient, newborn and adult mice of various genotypes and origin maintained on different genetic backgrounds, the functions of osteocalcin in the pancreas, liver and testes and their molecular underpinnings. This analysis revealed that providing mothers are Osteocalcin-deficient, Osteocalcin haploinsufficiency in embryos hampers insulin secretion, liver gluconeogenesis, glucose homeostasis, testes steroidogenesis in adult offspring; inhibits cell proliferation in developing pancreatic islets and testes; and disrupts distinct programs of gene expression in these organs and in the brain. This study indicates that osteocalcin exerts dominant functions in most organs it influences. Furthermore, through their synergistic regulation of multiple physiological functions, osteocalcin of maternal and embryonic origins contributes to the establishment and maintenance of organismal homeostasis in newborn and adult offspring.

Abstract
Light-harvesting 2 (LH2) and reaction-centre light-harvesting 1 (RC-LH1) complexes purified from the photosynthetic bacterium Rhodobacter (Rba.) sphaeroides were reconstituted into proteoliposomes either separately, or together at three different LH2:RC-LH1 ratios, for excitation energy transfer studies. Atomic force microscopy (AFM) was used to investigate the distribution and association of the complexes within the proteoliposome membranes. Absorption and fluorescence emission spectra were similar for LH2 complexes in detergent and liposomes, indicating that reconstitution retains the structural and optical properties of the LH2 complexes. Analysis of fluorescence emission shows that when LH2 forms an extensive series of contacts with other such complexes, fluorescence is quenched by 52.6 ± 1.4%. In mixed proteoliposomes, specific excitation of carotenoids in LH2 donor complexes resulted in emission of fluorescence from acceptor RC-LH1 complexes engineered to assemble with no carotenoids. Extents of energy transfer were measured by fluorescence lifetime microscopy; the 0.72 ± 0.08 ns lifetime in LH2-only membranes decreases to 0.43 ± 0.04 ns with a ratio of 2:1 LH2 to RC-LH1, and to 0.35 ± 0.05 ns for a 1:1 ratio, corresponding to energy transfer efficiencies of 40 ± 14% and 51 ± 18%, respectively. No further improvement is seen with a 0.5:1 LH2 to RC-LH1 ratio. Thus, LH2 and RC-LH1 complexes perform their light harvesting and energy transfer roles when reconstituted into proteoliposomes, providing a way to integrate native, non-native, engineered and de novo designed light-harvesting complexes into functional photosynthetic systems.
The Impact of Diglossia on Inflectional Morphological Constructions and Their Relation to Literacy Skills: A Longitudinal Study
Authors: Asadi Ibrahim A. , Asli-Badarneh Abeer , Ibrahim Raphiq , Hamzah Hussein 
Published: January 2024

Purpose:
This study examined the differences in spoken Arabic (SpA) and standard Arabic (StA) in inflectional (gender, number, possessive pronouns, and tense) construction use in Arabic among preschoolers. Moreover, we tested the contribution of the inflectional constructions possessed in kindergarten to reading skills in the first grade and examined whether this morphological contribution differs between SpA and StA.

Method:
We assessed 261 Arabic-speaking kindergartners for 1 year until the end of first grade for inflectional knowledge in kindergarten and reading skills in first grade (reading accuracy and fluency, spelling, and reading comprehension).

Results:
The findings revealed that among inflections, prevalence of performance on gender constructions was the highest, followed by number and possessive pronouns, and lowest performance for tense constructions. Although the performance for SpA was higher than for StA in all constructions, similar patterns were observed except similarity between gender and number in StA. Moreover, the results indicate a significant contribution of almost all inflectional constructions (except possessive pronouns) possessed in kindergarten to all reading skills in the first grade. However, tense did not contribute to reading comprehension, and possessive pronouns did not contribute to any of the reading measures. Regarding diglossia, although the claims that linguistic components in StA are not represented in the mental lexicon, StA accounted for an additional significant 2%–3% of the explained variance in Step 2 (which checked the practical significance of statistically significant results) in all reading measures.

Conclusions:
This study highlights the impact of diglossia-specific morphological differences (prevalence of the use of the morphological construction in Arabic in SpA vs. StA) on reading and literacy measures, especially the contribution of morphological awareness in SpA, which may provide a stronger basis for StA reading skills. The implications of these results are discussed, especially regarding exposing children to the morphological representations of both the SpA and StA forms to promote reading and literacy in Arabic.

Published: January 2024

AbstractPersistence of serum antiphospholipid antibodies (aPL) is associated with a high thrombotic risk, both arterial and venous, and with pregnancy complications. Due to the potential morbidity and mortality associated with the presence of aPL, identifying and recognizing risk factors for the development of aPL and thrombosis in aPL carriers may help to prevent and reduce the burden of disease. Multiple elements are involved in the pathomechanism of aPL development and aPL-related thrombosis such as genetics, malignancy, and infections. This review will address the role of both well-known risk factors and their evolution, and of emerging risk factors, including COVID-19, in the development of aPL and thrombosis in aPL carriers.
Governance mechanism of quality and safety of imported agricultural products in China based on grounded theory

Published: January 2024

AbstractWith the continuous improvement of economic development and people’s living standards, Chinese consumers are placing higher demands on the quality of imported agricultural products. The study adopts Grounded Theory to derive a theoretical model of the governance mechanism of quality and safety of imported agricultural products from the perspective of multiple subjects involved in governance and uses structural equation modeling to empirically validate the hypothesis. The results show that government regulation has a positive influence on the quality and safety of imported agricultural products. Importer regulation and consumer supervision can indirectly affect the quality and safety of imported agricultural products through government regulation. Consumer supervision positively affects the level of importer and government regulation and indirectly influences the quality and safety of imported agricultural products through active monitoring of the government and importers. Therefore, the government, importers, and consumers are the three parties who need to optimize their respective governance paths and enhance the quality and safety of imported agricultural products through collaborative governance.

The immobilization of Re(I) complexes onto metal oxide surfaces presents an elegant strategy to enhance their stability and reusability toward photocatalytic CO2 reduction. In this study, the photocatalytic performance of fac-[ClRe(CO)3(dcbH2)], where dcbH2 = 4,4′-dicarboxylic acid-2,2′-bipyridine, anchored onto the surface of 1%m/m CuO/Nb2O5 was investigated. Following adsorption, the turnover number for CO production (TONCO) in DMF/TEOA increased significantly, from ten in solution to 370 under visible light irradiation, surpassing the TONCO observed for the complex onto pristine Nb2O5 or CuO surfaces. The CuO/Nb2O5 heterostructure allows for efficient electron injection by the Re(I) center, promoting efficient charge separation. At same time CuO clusters introduce a new absorption band above 550 nm that contributes for the photoreduction of the reaction intermediates, leading to a more efficient CO evolution and minimization of side reactions.

Published: January 2024

Context Unmanned aerial vehicles (UAV) with red–green–blue (RGB) cameras are increasingly used as a monitoring tool in farming systems. This is the first field study in mungbean (Vigna radiata (L.) Wilzcek) using UAV and image analysis across multiple seasons. Aims This study aims to validate the use of UAV imagery to assess growth parameters (biomass, leaf area, fractional light interception and radiation use efficiency) in mungbean across multiple seasons. Methods Field experiments were conducted in summer 2018/19 and spring–summer 2019/20 for three sowing dates. Growth parameters were collected fortnightly to match UAV flights throughout crop development. Fractional vegetation cover (FVC) and computed vegetation indices: colour index of vegetation extraction (CIVE), green leaf index (GLI), excess green index (ExG), normalised green-red difference index (NGRDI) and visible atmospherically resistant index (VARI) were generated from UAV orthomosaic images. Key results (1) Mungbean biomass can be accurately estimated at the pre-flowering stage using RGB imagery acquired with UAVs; (2) a more accurate relationship between the UAV-based RGB imagery and ground data was observed during pre-flowering compared to post-flowering stages in mungbean; (3) FVC strongly correlated with biomass (R2 = 0.79) during the pre-flowering stage; NGRDI (R2 = 0.86) showed a better ability to directly predict biomass across the three experiments in the pre-flowering stages. Conclusion UAV-based RGB imagery is a promising technology to replace manual light interception measurements and predict biomass, particularly at earlier growth stages of mungbean. Implication These findings can assist researchers in evaluating agronomic strategies and considering the necessary management practices for different seasonal conditions.
Assessing coherence and fidelity

Published: January 2024

Abstract
Non-fictional narratives have an open-ended character that projects roles and values to those who participate in
them. Narrative participation, in turn, entails narrative assessment and identification processes, through which adherence to
values and positions may fail or be achieved. In the analysis of interviews with university students across Turkey, we draw on
Fisher’s narrative paradigm to focus on how our participants carry out assessments of narrative credibility. To elucidate
narrative coherence and fidelity, we take inspiration from an argumentative-rhetorical perspective, and focus specifically on the
relationship among the criteria identified in the literature on narrative assessment. Our study of interviewee evaluations of
COVID-19 narratives confirms the use of the coherence criteria, calls into question the fidelity criteria, and highlights the
relevance of identification as a basic process for fidelity assessments. We conclude by discussing our limitations and directions
for further research.

Abstract
We have measured the fission fragment mass-angle and mass-total kinetic energy (TKE) distributions for the neutron-deficient 190Pt compound nucleus (CN) populated via 12C + 178Hf reaction, at around and above barrier energies. No mass-angle correlation was observed in the fission of 190Pt signifying the absence of quasi-fission events in the studied reaction. The observed mass-TKE distributions have expected triangular shape and TKE distributions are well described with the single Gaussian fits, and mean TKE shows parabolic dependence on fragment mass as predicted based on liquid drop fission behaviour. The widths of measured TKE distributions agree well with the observed systematics for CN fission in this mass region. Though the CN is relatively neutron deficient, these observations suggest a clear picture of true CN fission behaviour for the chosen reaction in the studied energy domain.
Equivalent test method for continuous-wave high-field effects of aircraft equipment in four-core RVVP cable coupling channel

Abstract
In situations where there is ample space, constructing a high-field electromagnetic environment for radiated susceptibility testing of aircraft equipment can be difficult. This has necessitated the need for an equivalent test method. To address this issue, the response calculation models of the internal two-core pairs under radiation and injection conditions are established for the coupling channel of the four-core RVVP cable. The equivalent linear relationships between the two injected sources and the field intensity are derived, providing the foundation for obtaining equivalent injection sources and conducting linear extrapolation. Building on these findings, a specific equivalent test technology is proposed, based on the double bulk current injection. This technology is then verified through a pass-through load test for the continuous-wave high-field effects of aircraft equipment in the four-core RVVP cable coupling channel. The results of the tests demonstrated that the equivalent test method can accurately equate the high-field effects test with a maximum error of less than 1 dB. Moreover, it is applicable to nonlinear systems.

Abstract
In the realm of advanced materials research, high entropy alloys (HEAs) have emerged as a dynamic and rapidly evolving field, their potential can be further harnessed by developing HEA coatings on specific substrate materials. In this study, equiatomic AlBeSiTiV lightweight HEA (LWHEA) was successfully synthesized through the precise technique of mechanical alloying (MA). Subsequently, this innovative HEA coating was applied to the SS316 substrate using atmospheric plasma spray (APS). The microstructure of the synthesized HEA revealed a prominent FCC phase, with the coating having an average thickness of approximately 150 μm. Notably, the coated and coated annealed samples displayed improved microhardness of 985±13, and 1100±15 HV which was five and six times respectively that of the substrate. Electrochemical and hot corrosion tests were conducted on the substrate, coated, and coated annealed samples. The outcomes shed light on the profound impact of annealing in mitigating the corrosion rate as the porosity of the coated annealed samples was reduced to 2.53% which resulted in a significant reduction in corrosion rate when compared to coated samples. Hot corrosion tests demonstrated mass loss in the substrate due to the formation of iron oxide and subsequent spallation of it while mass gain in the coated and coated annealed samples due to oxide layer formation. Coated annealed samples exhibited lower mass gain in comparison to coated samples, showing reductions of 6% and 3% in Na2SO4/NaCl and Na2SO4/ V2O5, respectively. These findings underscore the immense promise of the annealed coating for applications demanding steadfast protection against corrosive challenges.
