Left/right entanglement and thermalization of time dependent plane wave Green-Schwarz superstring
Authors: Marchioro Dáfni F.Z. , Nedel Daniel Luiz 
Published: July 2020

Abstract
In this work we study new issues involving the type IIB superstring in a time dependent plane wave background with a constant self-dual Ramond-Ramond 5-form and a linear dilaton in the light-like direction. We construct a unitary Bogoliubov generator which relates the asymptotically flat superstring Hilbert space to the finite time Hilbert space. The time dependent vacuum is a superposition of SU(1, 1) × SU(2) coherent states, which has a particular structure of excitation, characterized by a condensation of right and left moving supertring modes. We calculate the time dependent left/right entanglement entropy and carry out the summation over the oscillator modes of the superstring two-point function. We show that, close to the null singularity, the entanglement entropy is well- behaved. In particular, for asymptotically flat observers, the closed superstring vacuum close to the singularity appears as superstring thermal vacuum, which is unitarily inequivalent to the asymptotically flat vacuum. Actually, we show that close to the singularity the superstring thermalizes and the entanglement entropy becomes a thermodynamical entropy for a supersymmetric two-dimensional gas.

AbstractDuring the manufacturing of ceramic components, grinding is an important manufacturing step. It influences the workpiece quality and the operational reliability. Thermomechanical loads during grinding can influence the lifetime and operational reliability of ceramics by modifying their bending strength and subsurface properties. Therefore, it is necessary to consider the influence of the grinding forces and mechanical loads on the strength of the ceramics in order to design a suitable grinding process. In this investigation, a quick-stop device is used to interrupt the grinding process of the newly developed mixed oxide ceramic SHYTZ (strontium hexaaluminate/yttria-toughened zirconia) and the market-established ceramic ATZ (alumina-toughened zirconia). Subsequently, an analysis of the occurring material removal phenomena, the number of active abrasive grains, and the real thermomechanical loads is carried out. It was found that the number of active grains and the material removal phenomena are influenced by the tool specifications. Besides that, the experimentally determined number of active grains was found to be up to 14 times higher than predicted by an analytical model given in literature. Consequently, the calculated single grain chip thickness was found to be up to 12.1% lower than analytically predicted. The investigation of the process forces and thermal loads showed up to 52% higher loads for ATZ than for SHYTZ. The subsequent analysis of the resulting bending strength of the ceramics revealed a lower influence of the grinding process on the strength of SHYTZ than for ATZ. Furthermore, a correlation between the used tool bonding and the resulting thermomechanical loads, bending strength, and residual stresses could be observed.

Published: July 2020

AbstractThe European brown hare (Lepus europaeus) is an important game species throughout Europe. In Italy, for preventing the introduction of allochthonous strains, the management of brown hare populations has focused on the establishment of small protected areas (ZRCs), appositely managed for disposing of wild-born hares for restocking hunting territories. We investigated the effects of both land cover and surveillance on hare density and habitat preferences in 20 ZRCs, monitored twice per year (pre- and post-breeding periods) between 1997 and 2017. Density, as assessed by spotlight counts, ranged between 2.8 and 47.0 ind/km2 in spring and 5.0 and 68.4 ind/km2 in autumn. Surveillance, percent length of protected boundaries, year of institution and habitat diversity, as assessed by Shannon’s Index, were the main factors affecting hare density. During their foraging activity, hares selected ryegrass, hayfields and lucerne, while avoided maize stubble and ploughed fields and were never recorded in poplar plantations or next to human settlements. While the effects of habitat heterogeneity on hare density have been widely studied, we suggest that the involvement of local stakeholders may be of paramount importance for ensuring effective conservation measures.
Supporting Adults with Intellectual Disabilities with Relationships and Sex: A Systematic Review and Thematic Synthesis of Qualitative Research with Staff
Authors: Charitou Maria , Quayle Ethel , Sutherland Alan 
Published: July 2020

AbstractStaff working with individuals with Intellectual Disabilities (ID) play an important role in enabling them to fulfill their sexual and romantic needs. Given the lack of recent reviews providing a synthesis of qualitative research in this population, the present review explored how staff working with individuals with ID in a variety of capacities (e.g. support workers, service managers, nurses, educators, psychologists, social workers) perceived their role in relation to supporting sexuality and relationships. A systematic search of EMBASE, PsychINFO, MEDLINE, CINAHL, ASSIA and SCOPUS was carried out and identified articles were rated against inclusion and exclusion criteria, as well as quality criteria. Findings were analyzed using thematic synthesis. The application of criteria resulted in the inclusion of 15 articles. Four themes were identified: (a) “Attitudes towards sexuality and relationships: A right and a challenge”, (b) “Responding to sexuality and relationships: A conflicted discourse”, (c) “Uncertainty and lack of systemic support”, and (d) “Influences on decision-making”. Findings suggest that staff hold ambivalent attitudes and often respond inconsistently to issues relating to service users’ sexuality. Role uncertainty, fear of accountability, lack of training and policy, as well as factors related to employing organizations and family caregivers were identified as barriers. The findings highlight the importance of providing training and supervision for staff in order to address ambivalent attitudes and anxieties, further developing national and local policy in relation to sexuality and relationships, and supporting family caregivers to meaningfully work alongside staff on issues relating to service users’ sexuality.
Critical review of recent development in fiber reinforced adobe bricks for sustainable construction
Authors: Salih Mahgoub M. , Osofero Adelaja I. , Imbabi Mohammed S. 
Published: July 2020

AbstractThis paper presents a state-of-the-art review of research on the utilization of fibers (predominantly derived from waste materials) as reinforcement in adobe brick production. Recycling of these wastes provides sustainable construction materials and helps to protect the environment. Specimen preparation and test procedures are outlined. The effects of addition of these wastes on the physical and mechanical properties of adobe bricks as presented in the literature, are investigated. The main results for each additive are presented and discussed. It is concluded that improved adobe brick properties can be expected with the addition of combination of waste additives. The use of waste materials in the construction industry is generally of interest and useful for engineers and designers seeking sustainable solutions in construction. It is also of interest to researchers actively seeking to develop methodical approaches to quantifying, optimising and testing the performance in use of such waste material additives.
Identifying early stages of reindeer domestication in the archaeological record: a 3D morphological investigation on forelimb bones of modern populations from Fennoscandia

Published: July 2020

AbstractReindeer herding probably developed during the Late Iron Age onwards and is still an important part of the subsistence and culture of many peoples in northern Eurasia. However, despite the importance of this husbandry in the history of these Arctic people, the period and place of the origin as well as the spread of domestic reindeer is still highly debated. Besides the existence of different breeding methods in these territories, identifying domesticated individuals in the archaeological record is complicated because reindeers are considered to still be in the early phases of the domestication process. Indeed, the traditional morphological markers used in zooarchaeology to decipher the domestication syndrome are hardly perceptible in these early stages. In this work, we propose solutions for identifying domestic reindeer bones using 3D geometric morphometrics on isolated elements from the long bones of the forelimb (i.e. humerus, radio-ulna and metacarpal). These bones are important to understand both the feeding behaviour and the mobility of reindeer, and the potential effect of load-carrying or draught in the case of domestic reindeer. We analysed 123 modern specimens from Fennoscandia, including the two interbreeding subspecies currently present in these territories: mountain reindeer (Rangifer tarandus tarandus) and forest reindeer (R.t. fennicus); and where the sex and the lifestyle were known (i.e. free-ranging, racing or draught and captive individuals). A good level of discrimination between the size and shape variables of the bones of the forelimb was found among both subspecies and sexes. Moreover, individuals bred in captivity had smaller bone elements and a thinner and more slender morphology than free-ranging individuals. This demonstrates that the long bones of the forelimb can provide information on changes in feeding and locomotor behaviour prompted by the domestication process, like control and/or reduction of mobility and food of individual reindeer by humans. This also demonstrates that analysis in 3D geometric morphometrics is useful in detecting reindeer incipient domestication markers. Our results can be used by archaeologists to trace the early stages of domestication from fossil reindeer remains, and aid in reconstructing the socio-economic changes of past Arctic populations over time.
Acceptance Towards LGB Persons Is an Independent Protective Factor Against Suicide on a Country Level
Authors: Stuke Heiner , Heinz Andreas , Bermpohl Felix 
Published: July 2020

Abstract
Background
Sexual minorities such as lesbian, gay, and bisexual (LGB) people have an increased risk for suicide, whose reasons are not sufficiently understood. We aimed to test if differences in LGB acceptance explain variations in general suicide rates on a country level.

Methods
We used linear regression models to explain the variation in age-standardized suicide rates in 34 OECD countries based on LGB acceptance, which was recently assessed in large international surveys polling the general population about their attitude towards homosexuality. We included economic and sociological variables, which have been shown to be related to suicide rates in previous work, as covariates. We then used backward elimination, leave-one-out cross-validation, and the Bayesian information criterion to identify best-fitting models (i.e., to select relevant predictors).

Results
All employed model selection methods favored a 4-predictor model, where higher LGB acceptance, fertility rate, religiosity, and unemployment rate were significantly related to lower suicide rates. Suicide rates were well explained by this sparse model (R2 adjusted = 0.442). In the full model with all predictors, as well as in the selected four-predictor model, higher LGB acceptance was significantly related to lower suicide rates.

Conclusions
Our findings suggest that low LGB acceptance, as measured by international surveys, might be a risk factor for suicide.
Writing for Local Government Schools: Authors and Themes in Song-dynasty School Inscriptions
Authors: Chen Song 
Published: July 2020

AbstractA hallmark of the Song dynasty's achievements was the creation of a national network of state-sponsored local schools. This engendered an exponential growth of commemorative inscriptions dedicated to local government schools. Many authors used these inscriptions as an avenue to expound and disseminate their visions of schools and education. Using the methods of network analysis and document clustering, this article analyzes all the inscriptions extant from Song times for local government schools. It reveals a structural schism in the diffusion of ideas between the Upper Yangzi and other regions of the Song. It also demonstrates the growing intellectual influence of Neo-Confucian ideologues that gradually overtook that of renowned prose-writers. Methodologically, this article provides an example of how diverse digital methods enable us to handle a large body of texts from multiple perspectives and invite us to explore connections we might not have otherwise thought of.

AbstractWe present the results of a new selection technique to identify powerful ($L_{\rm 500\,MHz} \gt 10^{27}\,\text{WHz}^{-1}$) radio galaxies towards the end of the Epoch of Reionisation. Our method is based on the selection of bright radio sources showing radio spectral curvature at the lowest frequency (${\sim}100\,\text{MHz}$) combined with the traditional faintness inK-band for high-redshift galaxies. This technique is only possible, thanks to the Galactic and Extra-galactic All-sky Murchison Wide-field Array survey which provides us with 20 flux measurements across the 70–$230\,\text{MHz}$range. For this pilot project, we focus on the GAMA 09 field to demonstrate our technique. We present the results of our follow-up campaign with the Very Large Telescope, Australian Telescope Compact Array, and the Atacama Large Millimetre Array to locate the host galaxy and to determine its redshift. Of our four candidate high-redshift sources, we find two powerful radio galaxies in the$1<z<3$range, confirm one at$z=5.55$, and present a very tentative$z=10.15$candidate. Their near-infrared and radio properties show that we are preferentially selecting some of the most radio luminous objects, hosted by massive galaxies very similar to powerful radio galaxies at$1<z<5$. Our new selection and follow-up technique for finding powerful radio galaxies at$z>5.5$has a high 25–50% success rate.

Published: July 2020

AbstractBackgroundPatients with obsessive-compulsive disorder (OCD) are at increased risk for suicide attempt (SA) compared to the general population. However, the significant risk factors for SA in this population remains unclear – whether these factors are associated with the disorder itself or related to extrinsic factors, such as comorbidities and sociodemographic variables. This study aimed to identify predictors of SA in OCD patients using a machine learning algorithm.MethodsA total of 959 outpatients with OCD were included. An elastic net model was performed to recognize the predictors of SA among OCD patients, using clinical and sociodemographic variables.ResultsThe prevalence of SA in our sample was 10.8%. Relevant predictors of SA founded by the elastic net algorithm were the following: previous suicide planning, previous suicide thoughts, lifetime depressive episode, and intermittent explosive disorder. Our elastic net model had a good performance and found an area under the curve of 0.95.ConclusionsThis is the first study to evaluate risk factors for SA among OCD patients using machine learning algorithms. Our results demonstrate an accurate risk algorithm can be created using clinical and sociodemographic variables. All aspects of suicidal phenomena need to be carefully investigated by clinicians in every evaluation of OCD patients. Particular attention should be given to comorbidity with depressive symptoms.
Religiosity and health among Chinese older adults: a meta-analytic review
Authors: Li Jia , Wang Qi 
Published: July 2020

AbstractThe ageing population has been rapidly growing over recent years. Theoretically, religion seemingly plays an important role in improving older people's health. This study examines whether believing in religion is related to better health conditions among Chinese older adults through a meta-analysis. Two researchers independently extracted the studies from a comprehensive database and grey literature search and evaluated their scientific quality. From the 3,777 potentially eligible papers, just 76 were selected. The pooled effect size detected no significant difference between Chinese religious and non-religious older adults’ overall health and wellbeing. Dividing the outcomes into different categories, religious older adults reported both a higher level of anxiety (Hedge'sg= −0.392, 95% confidence interval (CI) = −0.494, −0.290;p= 0.004) and yet a higher level of happiness (Hedge'sg= 0.342, 95% CI = 0.074, 0.610;p= 0.018). Having a higher proportion of females in the sample is related to a smaller effect size in overall health outcomes (β = −2.205, 95% CI = −3.800, −0.613;p= 0.007) and social support specifically (β = −4.660, 95% CI = −6.261, −3.058;p< 0.0001). This study is among the first to synthesise the quantitative evidence regarding health differences between older religion believers and non-believers in China. It calls for future studies investigating the pathways underlying the religion–health relationship.

AbstractWhile medical nutrition therapy is an essential part of the care for critically ill patients, uncertainty exists about the right form, dosage, timing and route in relation to the phases of critical illness. As enteral nutrition (EN) is often withheld or interrupted during the intensive care unit (ICU) stay, combined EN and parenteral nutrition (PN) may represent an effective and safe option to achieve energy and protein goals as recommended by international guidelines. We hypothesise that critically ill patients at high nutritional risk may benefit from such a combined approach during their stay on the ICU. Therefore, we aim to test if an early combination of EN and high-protein PN (EN+PN) is effective in reaching energy and protein goals in patients at high nutritional risk, while avoiding overfeeding. This approach will be tested in the here-presented EFFORTcombo trial. Nutritionally high-risk ICU patients will be randomised to either high (≥2·2 g/kg per d) or low protein (≤1·2 g/kg per d). In the high protein group, the patients will receive EN+PN; in the low protein group, patients will be given EN alone. EN will be started in accordance with international guidelines in both groups. Efforts will be made to reach nutrition goals within 48–96 h. The efficacy of the proposed nutritional strategy will be tested as an innovative approach by functional outcomes at ICU and hospital discharge, as well as at a 6-month follow-up.
Geologic Map of Aphrodite Map Area (AMA; I‐2476), Venus
Authors: Hansen V. L. , López I. 
Published: July 2020

AbstractWe present a 1:10‐M‐scale geologic map of the Aphrodite Map Area (AMA) of Venus (0°N–57°S/60–80°E). Geologic mapping employed NASA Magellan synthetic aperture radar and altimetry data. The AMA geologic map, with detailed structural elements and geologic units covering over one eighth of Venus' surface, affords an important and unique perspective to test models of global‐scale geologic processes through time. Geologic relations record a history inconsistent with global catastrophic resurfacing. The AMA displays a regional coherence of preserved geologic patterns that record three sequential geologic eras: the ancient era, the Artemis superstructure era, and the youngest fracture zone era. The ancient era and Artemis superstructure, with a footprint covering more than 25% of the surface, are recorded in the Niobe Map Area to the north. The latter two eras likely overlap in time. The fracture zone domain, part of a globally extensive province, marks the most spatially focused tectonomagmatic domain within the AMA. Impact craters are both cut by and overprint fracture zone structures. Twelve percent of AMA impact craters that occur within the fracture zone domain predate or formed during fracture zone development. This observation indicates the relative youth of the fracture zone era and is consistent with the possibility that this domain remains geologically active. The AMA records a rich geologic history of large tract of the surface of Venus and provides an important framework to formulate new working hypotheses of Venus evolution and contribute to planning future studies of the surface of planets.
Exploring the impact of trauma type and extent of exposure on posttraumatic alterations in 5-HT1A expression

Published: July 2020

AbstractThe long-term behavioral, psychological, and neurobiological effects of exposure to potentially traumatic events vary within the human population. Studies conducted on trauma-exposed human subjects suggest that differences in trauma type and extent of exposure combine to affect development, maintenance, and treatment of a variety of psychiatric syndromes. The serotonin 1-A receptor (5-HT1A) is an inhibitory G protein-coupled serotonin receptor encoded by theHTR1Agene that plays a role in regulating serotonin release, physiological stress responding, and emotional behavior. Studies from the preclinical and human literature suggest that dysfunctional expression of 5-HT1A is associated with a multitude of psychiatric symptoms commonly seen in trauma-exposed individuals. Here, we synthesize the literature, including numerous preclinical studies, examining differences in alterations in 5-HT1A expression following trauma exposure. Collectively, these findings suggest that the impact of trauma exposure on 5-HT1A expression is dependent, in part, on trauma type and extent of exposure. Furthermore, preclinical and human studies suggest that this observation likely applies to additional molecular targets and may help explain variation in trauma-induced changes in behavior and treatment responsivity. In order to understand the neurobiological impact of trauma, including the impact on 5-HT1A expression, it is crucial to consider both trauma type and extent of exposure.
