Fragile Heterosexuality: Do Sexual Minorities also Perceive Heterosexuality as Fragile?
Authors: Borras Guevara Martha Lucia , West Keon 
Published: May 2023

AbstractPrevious evidence shows that heterosexual people perceive heterosexual status to be more fragile than homosexual status. However, research has not yet investigated whether sexual minorities have similar, or diverging, perceptions of the fragility of sexual orientation. With a sample that included 89 heterosexual and 80 sexual minority participants, we investigated the fragility of heterosexuality using a between-participants design in which participants indicated their agreement with gender neutral statements about the fragility of either heterosexual or homosexual status. Contrary to our expectations we found evidence of Fragile Heterosexuality perceptions regardless of participants’ sexual orientation. Additionally, we explored the potential moderating effects of social-dominance orientation, right-wing authoritarianism and prejudice against gay/lesbian people on this Fragile Heterosexuality effect. For sexual minority participants, high levels of social dominance orientation moderated (i.e., increased) the perceived fragility of heterosexual identity relative to homosexual identity. No other inter-group ideology was a significant moderator. These findings highlight that heterosexuality is perceived as more fragile by both heterosexual and sexual minority individuals. Implications and possible avenues for future research are discussed.

AbstractThis paper addresses how emotionally challenging experiences during work-based education may influence the professional becoming of student teachers and medical students. We conducted a qualitative analysis of eight focus group interviews with undergraduates from two universities in Sweden who studied to become either physicians or teachers, and interpreted their experiences through Wenger’s theory of communities of practice. The findings show that students’ ideal view of how to be caring in their aspiring professional role as physician or teacher collided with existing practices, which affected them emotionally. In particular, the students found it challenging when norms and practices differed from their values of professionalism and when the professional culture within practices reflected hardness (physicians) or resignation (teachers). Both medical students and student teachers experienced that professional decision making and legitimacy challenged them emotionally, however in different ways and for different reasons. This study makes visible both general and specific aspects of how students view their future role in the welfare sector and challenging dimensions of professional practice. The findings bring into focus the question of how professional education can support students’ professional becoming in relation to their emotional challenges.

AbstractStroke and perinatal asphyxia have detrimental effects on neuronal cells, causing millions of deaths worldwide each year. Since currently available therapies are insufficient, there is an urgent need for novel neuroprotective strategies to address the effects of cerebrovascular accidents. One such recent approach is based on the neuroprotective properties of estrogen receptors (ERs). However, activation of ERs by estrogens may contribute to the development of endometriosis or hormone-dependent cancers. Therefore, in this study, we utilized ospemifene, a novel selective estrogen receptor modulator (SERM) already used in dyspareunia treatment. Here, we demonstrated that posttreatment with ospemifene in primary neocortical cell cultures subjected to 18 h of hypoxia and/or ischemia followed by 6 h of reoxygenation has robust neuroprotective potential. Ospemifene partially reverses hypoxia- and ischemia-induced changes in LDH release, the degree of neurodegeneration, and metabolic activity. The mechanism of the neuroprotective actions of ospemifene involves the inhibition of apoptosis since the compound decreases caspase-3 overactivity during hypoxia and enhances mitochondrial membrane potential during ischemia. Moreover, in both models, ospemifene decreased the levels of the proapoptotic proteins BAX, FAS, FASL, and GSK3β while increasing the level of the antiapoptotic protein BCL2. Silencing of specific ERs showed that the neuroprotective actions of ospemifene are mediated mainly via ESR1 (during hypoxia and ischemia) and GPER1 (during hypoxia), which is supported by ospemifene-evoked increases in ESR1 protein levels in hypoxic and ischemic neurons. The results identify ospemifene as a promising neuroprotectant, which in the future may be used to treat injuries due to brain hypoxia/ischemia.
Group Diagrams for simplified representation of scanpaths
Authors: Schäfer Peter , Rodrigues Nils , Weiskopf Daniel , Storandt Sabine 
Published: May 2023

Abstract
We instrument Group Diagrams (GDs) to reduce clutter in sets of eye-tracking scanpaths. Group Diagrams consist of trajectory subsets that cover, or represent, the whole set of trajectories with respect to some distance measure and an adjustable distance threshold. The original GDs allow for an application of various distance measures. We implement the GD framework and evaluate it on scanpaths that were collected by a former user study on public transit maps. We find that the Fréchet distance is the most appropriate measure to get meaningful results, yet it is flexible enough to cover outliers. We discuss several implementation-specific challenges and improve the scalability of the algorithm. To evaluate our results, we conducted a qualitative study with a group of eye-tracking experts. Finally, we note that our enhancements are also beneficial within the original problem setting, suggesting that our approach might be applicable to various types of input data.

AbstractRull cave is a karstic cave located in Vall d’Ebo (Alicante, Southeast of Spain) developed in massive Miocene conglomerates and Cretaceous limestones. Processes in soil above Rull cave and outdoor atmosphere directly influence the underground environment of the cave. Continuous and discrete monitoring of cave atmosphere and soil (from 2012 to 2022) allows to characterise the spatial distribution and temporal variations of the gaseous concentration (222Rn and CO2) and understand the relationship between the processes which occurred in the 3-component system (soil-cave-atmosphere). Besides the presence of visitors, Rull cave maintains stable values of mean temperature (16.2 °C) and relative humidity (97.6%). In an annual cycle the cave presents two different gaseous stages (stagnation and ventilation). Maximum average values of CO2 and 222Rn concentration are reached within the stagnation stage, in the warmest period of the year. On the contrary, in the ventilation stage (in the coldest months) the cave reaches the lowest concentrations in its inner atmosphere. For the study period, daily average CO2 and 222Rn concentrations are 2008 ppm and 1745 Bq/m3, respectively. Results show that the dynamics of 222Rn and CO2 in the cave air follow different patterns defined by the complex relationships between external and internal factors. Findings from this study provide substantial information about the environmental situation of the cave atmosphere in terms of air quality for visitors and workers.

Published: May 2023

Abstract
Objectives
The COVID-19 pandemic resulted in a dramatic increase in Web-based education, lacking face-to-face student–teacher and student–student interaction, and consequently impairing students’ sense of belonging to a community, interoceptive awareness, and academic self-efficacy. This study examined how a brief mindfulness-based intervention in an online university course can be effective in enhancing attention resources, developing a stronger sense of academic self-efficacy, and improving the sense of belonging to a community, which represent critical factors affecting students’ participation in online and blended courses.

Method
Four-hundred and eighty-six participants (Mage 22.88) completed a battery of measures at pre- and post-treatment. One class (experimental group) participated in a brief online mindfulness-based intervention (42%), whereas the other one (control group) did not take part in the intervention (58%). The intervention included breathing meditation at the beginning of class, sharing of experiences, mini-lectures on mindfulness, and daily practice, and lasted for 28 consecutive days.

Results
Participants in the experimental group when compared to controls showed a significant increase in the feeling of influencing the course activities (F = 9.628; p < 0.005), in the self-regulation of attention (F = 19.133; p < 0.001), in academic self-efficacy (F = 9.220; p < 0.005), and, particularly, in their self-efficacy in regulating learning (F = 12.942; p < 0.001). The students’ adherence to the assigned practice could partially explain the effectiveness of the intervention.

Conclusions
This study offers useful clues about the effectiveness of mindfulness interventions in the classroom in enhancing sense of belonging to a community, attention grounded in bodily sensations, and academic self-efficacy.

Interactions and Covariation of Ecological Drivers Control CO2 Fluxes in an Alpine Peatland
Authors: Carbognani Michele , Tomaselli Marcello , Petraglia Alessandro 
Published: May 2023

AbstractPeatland ecosystems are a highly effective long-term carbon sink. However, the CO2 fluxes could be substantially altered by climate changes and the fate of carbon stored in these ecosystems is still uncertain. Currently, most studies concerning the carbon fluxes in peatlands were performed at high latitude sites, where these ecosystems are more widely distributed compared to temperate regions, where peatlands are less frequent and, in addition to climate pressure, increasingly threatened by human activities. However, the information we have on these peatlands is very scarce. To fill this knowledge gap, we studied CO2 fluxes in an alpine peatland, through light and dark incubations. Using the natural variation in ecological conditions, we identified the main drivers of CO2 fluxes, considering in particular their interactions and covariation. Ecosystem respiration and gross primary production were primarily stimulated by the lowering of the water table and the amount of photosynthetic radiation, respectively, whereas net ecosystem CO2 exchange showed greater variation along the growing season. The influence on CO2 fluxes of the interactions between the drivers investigated, including soil temperature and moisture as well as vegetation type and plant functional diversity, was found to be of pivotal importance. Finally, a substantial part of the variation in CO2 emission and uptake processes was regulated by the joint variation of atmospheric and edaphic factors. To understand and predict the CO2 dynamics of alpine peatlands, it is necessary to consider the interplays among ecological factors, especially in relation to the expected changes in climate and vegetation.

AbstractThe SARS-CoV-2 pandemic has highlighted the importance of viable infection surveillance and the relevant infrastructure. From a German perspective, an integral part of this infrastructure, genomic pathogen sequencing, was at best fragmentary and stretched to its limits due to the lack or inefficient use of equipment, human resources, data management and coordination. The experience in other countries has shown that the rate of sequenced positive samples and linkage of genomic and epidemiological data (person, place, time) represent important factors for a successful application of genomic pathogen surveillance. Planning, establishing and consistently supporting adequate structures for genomic pathogen surveillance will be crucial to identify and combat future pandemics as well as other challenges in infectious diseases such as multi-drug resistant bacteria and healthcare-associated infections. Therefore, the authors propose a multifaceted and coordinated process for the definition of procedural, legal and technical standards for comprehensive genomic pathogen surveillance in Germany, covering the areas of genomic sequencing, data collection and data linkage, as well as target pathogens. A comparative analysis of the structures established in Germany and in other countries is applied. This proposal aims to better tackle epi- and pandemics to come and take action from the “lessons learned” from the SARS-CoV-2 pandemic.
The Role of Combat Zone Exposure in Development of Upper Airway Inflammatory Disease
Authors: McCormick Justin P. , Lee Jivianne T. 
Published: May 2023

Abstract
Purpose of review
Soldiers returning from deployment often complain of new-onset respiratory disease upon their return. It is known that exposure to higher levels of air pollution may occur while on deployment, and air pollution exposure has been identified as a risk factor for development of upper respiratory disease. The purpose of this review is to report findings from recent research regarding pollutant exposure and upper respiratory tract disease among military veterans.

Recent findings
The prevalence of both allergic rhinitis and chronic rhinosinusitis is increased among deployed veterans compared to non-deployed counterparts. Deployed service members are also exposed to pollutants at up to 100 × that which is considered acceptable in the United States (U.S.).

Summary
Deployed military members may be more prone to developing chronic upper respiratory conditions compared to their non-deployed counterparts, and this may be related to exposures overseas which are not routinely encountered in the U.S.
Experimental study on the nonlinear flow characteristics of fractured granite after high-temperature cycling
Authors: Li Tao , Zhang Qiang , Yin Qian , Dai Wanli , Gu Jiayu 
Published: May 2023

AbstractTo understand the influence of temperature on the flow characteristics of fractured granite, high-temperature cyclic thermal treatment and flow tests on the fractured rock sample with different joint roughness coefficients and intact rock samples were conducted. The larger confining pressure and larger joint roughness coefficient will increase the resistance of fluid flow and affect the flow characteristics of the fluid. With the temperature increasing, the aperture of the fractures, the number of micro-fractures, and micropores increase which forms a large number of new connected hydraulic channels in the matrix. Forchheimer's law and Izbash equation can well describe the nonlinear flow characteristics, and the fitting coefficients are greater than 0.99. As the increasing temperature, the slope of the curve between the volumetric flow rate and pressure gradient gradually decreases, and the coefficients in Forchheimer's law and the Izbash equation decrease. The transmissivity decrease with the increasing Reynolds number and the change range of that increase with the increasing temperature. When the temperature is at the lower level (T = 200 ~ 600 °C), the contribution of split fracture to the permeability is greater than that of the matrix. When the temperature continuously increases to 800 °C, the contribution of the matrix to the permeability gradually rises and then exceeds that of split fracture. The results indicate that 400 °C is the critical temperature, after which the flow characteristics of fractured granite after high-temperature cycling change more obviously.
Effect of Molybdenum Contents on Microstructure and High-Temperature Wear Behavior of SiMo Ductile Iron

Published: May 2023

AbstractHigh-silicon and molybdenum (SiMo) ductile iron is a common heat-resistant alloy that may be exposed to high-temperature wear during service in many of its applications. The wear behavior of four SiMo ductile iron alloys was evaluated at different temperatures up to 750 °C. This research focuses on the influence of various Mo contents on the microstructure, structural stability, and hence, the wear performance of such alloys. Thermodynamic calculations proposed the phase diagrams, critical transformation temperatures, and phase volume fractions in all samples by means of Thermo-Calc software. The dilatometry measurements were carried for confirming the theoretical results of Thermo-Calc thermodynamic calculations. The results revealed that the microstructure of SiMo ductile cast iron consists of nodular graphite and a ferrite matrix with carbides embedded in the fine precipitates at the grain boundary regions. The type of carbides and the nature of these fine precipitates are discussed according to EDX and SEM results. Adding molybdenum enhanced the wear performance of SiMo by decreasing the weight loss by about 40–70% compared to a Mo-free alloy. This is due to the increased molybdenum carbides, which increase hardness and improve wear resistance in SiMo alloys. The high temperatures have a negative effect on reducing the wear resistance at 250 °C. On the other hand, the wear resistance unexpectedly started to increase at higher temperatures of 500 °C and 750 °C because of the contribution of oxidative wear with abrasive wear by forming a protective oxide layer. Furthermore, the obtained results supported the idea that adding molybdenum improves wear resistance at high temperatures. Hence, SiMo has the potential to be wear-resistant material in wider applications requiring high-temperature wear resistance.
Moluccan Fighting Craft on Australian Shores: Contact Rock Art from Awunbarna, Arnhem Land

Published: May 2023

AbstractTwo similar watercraft depicted in rock art at Awunbarna, Arnhem Land, Australia, are unlike the Macassanprahusand Western craft shown at other contact sites in northern Australia, but are sufficiently detailed to offer evidence for identification. Both craft appear to display triangular flags, pennants, and prow adornments indicating martial status. By comparing these two depictions with historically recorded watercraft from Island Southeast Asia, their probable origin is shown to have been eastern Maluku Tenggara in Indonesia. These motifs provide the first known direct archaeological evidence for ethnic diversity for the origins of mariners from Island Southeast Asia other than Makassar, Sulawesi. The rock-art depictions are representative of ceremonially decorated fighting craft used to lead trading voyages and raids, and may be linked to trade, fishing, resource exploitation, or slavery. This potentially unique identification of Moluccan watercraft in Arnhem Land rock art offers evidence of the elusive encounters between the Indigenous people of northern Australia and people from the archipelagos to the north, evidence with which to expand both the nature and context of Australia’s contact narrative.
Quantum Advantage Seeker with Kernels (QuASK): a software framework to speed up the research in quantum machine learning

Published: May 2023

AbstractExploiting the properties of quantum information to the benefit of machine learning models is perhaps the most active field of research in quantum computation. This interest has supported the development of a multitude of software frameworks (e.g. Qiskit, Pennylane, Braket) to implement, simulate, and execute quantum algorithms. Most of them allow us to define quantum circuits, run basic quantum algorithms, and access low-level primitives depending on the hardware such software is supposed to run. For most experiments, these frameworks have to be manually integrated within a larger machine learning software pipeline. The researcher is in charge of knowing different software packages, integrating them through the development of long code scripts, analyzing the results, and generating the plots. Long code often leads to erroneous applications, due to the average number of bugs growing proportional with respect to the program length. Moreover, other researchers will struggle to understand and reproduce the experiment, due to the need to be familiar with all the different software frameworks involved in the code script. We propose QuASK, an open-source quantum machine learning framework written in Python that aids the researcher in performing their experiments, with particular attention to quantum kernel techniques. QuASK can be used as a command-line tool to download datasets, pre-process them, quantum machine learning routines, analyze and visualize the results. QuASK implements most state-of-the-art algorithms to analyze the data through quantum kernels, with the possibility to use projected kernels, (gradient-descent) trainable quantum kernels, and structure-optimized quantum kernels. Our framework can also be used as a library and integrated into pre-existing software, maximizing code reuse.

AbstractBiomaterials are routinely used in dentistry for tissue engineering. The purpose of the present work is to compare the performance of a new alloplastic biomaterial (Blue-Bone®), xenogeneic biomaterial (Bio-Oss®), and a mixture of both biomaterials with 50% of autogenous bone. 32 Wistar rats underwent a surgical procedure in which a circular disc of bone was removed from the calvaria with a trephine drill 10 mm in diameter to create a critical bone defect, which was filled with the biomaterials under study. After 40 days, the animals were euthanized and the calvaria was removed for processing and analysis. Histomorphometric determination of vital mineralized tissue (VMT), no-vital mineralized tissue (NVMT), and on-mineralized tissue (NVMT) was performed. The results showed that, while cavities filled with Bio-Oss® needed to be mixed with an autogenous bone to present better performance, Blue-Bone® biomaterial does not need to be mixed with an autogenous bone to promote a more cellular and vascularized bone matrix.
