Embedded in the Bark: Kimberley Boab Trees as Sites of Historical Archaeology
Authors: K. Frederick Ursula , Balme Jane , Jamieson Jeffrey , Marshall Melissa , O’Connor Sue 
Published: December 2022

AbstractThis paper discusses the Australian boab tree and its potential for research as living historical archaeology. Boab trees play an important role in the economy, culture, and cosmology of Indigenous people in northwest Australia and continue to hold a powerful presence in the Kimberley region today. Working with Nyikina and Mangala Traditional Owners we have undertaken to document examples of this iconic tree and its cultural and historical associations, particularly in the form of carvings and inscriptions embedded in the bark. Focusing on four individual trees located in the Kimberley region of northwest Australia, we propose that the modification of boab trees, as a practice undertaken by both Indigenous and non-Indigenous people, offers important insights into the everyday lives and historic events that shaped this cultural landscape.
Photopyroelectric Investigation of the trans–cis Isomerization Effect on the Nematic- Isotropic Phase Transition of a Liquid Crystalline Azobenzene

Published: December 2022

AbstractPhotopyroelectric calorimetry has been applied to the study of the effects of different concentration of photo-induced cis isomeric molecules on the characteristics of the nematic – isotropic phase transition in p,p’-diheptylazobenzene (7AB) samples. The investigations could be carried out by monitoring the behavior of the thermal diffusivity over the phase transition before and during the sample irradiation with UV light of varying intensity. Among other, it is shown that the monitoring of the time dependence of the thermal diffusivity at fixed sample temperature enabled the comparative study of the dynamics of the trans–cis and cis–trans isomeric transitions. It was shown that the increasing cis isomers concentration caused an increase in the fraction of material undergoing the phase transitions and increased the cis–trans conversion rate. Finally, polarization microscopy observations of the sample texture, which could be carried out together with the calorimetric evaluations proved useful for a more comprehensive analysis of the obtained results.
Generic Exact Combinatorial Search at HPC Scale
Authors: MacGregor Ruairidh , Archibald Blair , Trinder Phil 
Published: December 2022

AbstractExact combinatorial search is essential to a wide range of important applications, and there are many large problems that need to be solved quickly. Searches are extremely challenging to parallelise due to a combination of factors, e.g. searches are non-deterministic, dynamic pruning changes the workload, and search tasks have very different runtimes. YewPar is a C++/HPX framework that generalises parallel search by providing a range of sophisticated search skeletons.This paper demonstrates generic high performance combinatorial search, i.e. that a variety of exact combinatorial searches can be easily parallelised for HPC using YewPar. We present a new mechanism for profiling key aspects of YewPar parallel combinatorial search, and demonstrate its value. We exhibit, for the first time, generic exact combinatorial searches at HPC scale. We baseline YewPar against state-of-the-art sequential C++ and C++/OpenMP implementations. We demonstrate that deploying YewPar on an HPC system can dramatically reduce the runtime of large problems, e.g. from days to just 100s. The maximum relative speedups we achieve for an enumeration search are near-linear up to 195(6825) compute-nodes(workers), super-linear for an optimisation search on up to 128(4480) (pruning reduces the workload), and sub-linear for decision searches on up to 64(2240) compute-nodes(workers).
Domains of ordering
Authors: Branan Kenyon 
Published: December 2022

AbstractThis paper develops a theory of linearization in which the LCA (Kayne, The antisymmetry of syntax, MIT Press, 1994) linearizes one portion of the clause, with a secondary algorithm linearizing a second portion of the clause when the LCA-determined order of terminals would conflict with other principles of the morphosyntax. The empirical focus is the correspondence or lack thereof between scope and word order in Japanese, Tagalog, and English: for one portion of the clause, there is a strict correspondence between the linear order of certain elements and their scope, while for another portion of the clause, this correspondence breaks down. Given a theory of LCA-determined linear order and clause structure following Biberauer [Linguist Inq 45(2):169–225, 2014], alongside a restricted theory of reconstruction, we show that the portion of the clause for which the LCA determines linear order is that which displays the strict correspondence between linear order and scope, while that for which the secondary algorithm determines linear order is where the correspondence between scope and linear order breaks down.

AbstractBackgroundPlatelet glycoprotein VI (GPVI) receptor is essential for platelet adhesion and aggregation. Eltrombopag is as an effective treatment for chronic immune thrombocytopenia (ITP); yet, its effect on platelet function is not fully characterized.AimThis prospective study investigated the effect of eltrombopag therapy on platelet function through assessment of GPVI receptor expression and soluble GPVI levels among pediatric patients with persistent or chronic ITP.MethodsThirty-six children and adolescents with persistent or chronic ITP were divided equally into two groups either to receive eltrombopag therapy or the standard of care. All patients were followed-up for 12 months with assessment of bleeding score and complete blood count (CBC). Evaluation of GPVI expression using flow cytometry and measurement of its soluble form by ELISA was done at baseline and at 6 months.ResultsITP patients on eltrombopag had significantly lower bleeding score after 6 months of therapy while the quality of life has significantly improved. Platelet count was significantly increased throughout the study. GPVI expression by flow cytometry and soluble GPVI levels were significantly increased after eltrombopag therapy. After 12 months, ITP patients on eltrombopag were able to maintain a good quality of life and low bleeding score.ConclusionOur data suggest that eltrombopag, through its effect on the GPVI receptor expression and its soluble form, might reduce bleeding manifestations and improve the quality of life of chronic and persistent ITP children independent of its effect on the platelet count.
Revisiting Consistency Regularization for Semi-Supervised Learning
Authors: Fan Yue , Kukleva Anna , Dai Dengxin , Schiele Bernt 
Published: December 2022

AbstractConsistency regularization is one of the most widely-used techniques for semi-supervised learning (SSL). Generally, the aim is to train a model that is invariant to various data augmentations. In this paper, we revisit this idea and find that enforcing invariance by decreasing distances between features from differently augmented images leads to improved performance. However, encouraging equivariance instead, by increasing the feature distance, further improves performance. To this end, we propose an improved consistency regularization framework by a simple yet effective technique, FeatDistLoss, that imposes consistency and equivariance on the classifier and the feature level, respectively. Experimental results show that our model defines a new state of the art across a variety of standard semi-supervised learning benchmarks as well as imbalanced semi-supervised learning benchmarks. Particularly, we outperform previous work by a significant margin in low data regimes and at large imbalance ratios. Extensive experiments are conducted to analyze the method, and the code will be published.
The political power of internet business: A comprehensive dataset of Telecommunications Ownership and Control (TOSCO)
Authors: Freyburg Tina , Garbe Lisa , Wavre Véronique 
Published: December 2022

AbstractThe ‘internet’—familiar shorthand for information and communication technologies (ICT)—is built on a physical infrastructure owned by a variety of state and private actors, foreign and domestic, with multiple interests. It has not only driven change on a global scale; its spread also had a profound impact on the social sciences. However, our understanding of how its architecture, and especially its owners, influence its political and economic impact is still in its infancy. This paper presents the Telecommunications Ownership and Control (TOSCO) dataset on ownership of internet service providers (ISPs) that allows to recognize the internet as strategically built and used by governments and corporations. Along with a thorough discussion of the conceptualization and operationalization of ownership as a variable, the TOSCO dataset enables comparative large-Nanalysis of the determinants and effects of varying ownership structures and identities in the transforming context of 49 African countries, 2000–2019. We demonstrate its usefulness with descriptive statistics and regression analyses using replication data from research on the internet’s democratizing and corruption-reducing effects. In allowing for a more realistic account, TOSCO supports scholars and practitioners concerned with the determinants and effects of internet service provision, use and control in Africa and beyond.

Published: December 2022

Abstract
Introduction
Intussusceptions diagnosed on computed tomography (CT) scans in Roux-en-Y gastric bypass (RYGB) patients could cause serious small bowel obstruction (SBO) or be an incidental finding. The objective of this study was to correlate radiological findings with clinical outcomes to differentiate intussusceptions requiring emergent surgery for SBO.

Methods
A search for acute abdominal CT scans reporting intussusceptions in RYGB patients between 2012 and 2019 at Skåne University Hospital, Malmö, Sweden, retrieved 35 scans. These were independently reevaluated by two radiologists for the length and location of the intussusception, whether oral contrast passed through, proximal bowel dilatation, and signs of internal herniation. Clinical outcome in terms of emergency surgery and the diagnosis was determined through chart review.

Results
Out of 35 acute patients, 9 patients required emergency surgery within 24 h. Intussusception caused SBO in five patients, and one patient had an internal herniation, while three patients had unremarkable findings. Eight patients were evaluated for intermittent pain with five unremarkable laparoscopies, while 18 patients had intussusceptions as incidental findings. Intussusception length on CT as measured by radiologists O.E. and D.L. predicted acute bowel obstruction (p = .014 and p < .001). A 100 mm threshold predicted bowel obstruction with a sensitivity of 80% and 100% and a specificity of 93% and 86% by radiologists O.E. and D.L., respectively. Proximal bowel dilatation predicted SBOs of any cause as well as SBO caused by an intussusception (all p < .05).

Conclusion
Intussusception length > 100 mm on CT in RYGB patients is an easy and valuable sign indicating SBO that may require emergent surgery.

AbstractIn Alzheimer's disease (AD), neuroinflammation is detrimental in causing neurodegeneration. In the central nervous system, inhibitor of nuclear factor kappa B kinase subunit beta (IKK2/IKKβ/IKKB/IKBKB) signaling is linked to neuroinflammation-mediated learning and memory deficits through canonical pathway, while dopamine agonists have been known to reverse such effects. Our in silico analysis predicted if dopaminergic agonists could have IKKB inhibitory actions, to ameliorate neuroinflammation-associated learning and memory deficits. Here, the FDA-approved Zinc 15 database was screened with IKKB (PDB ID 4KIK). Potential molecules with IKKB inhibition were identified through docking, which also possessed dopaminergic activity. Molecular mechanics—generalized Born and surface area (MMGBSA), induced fit docking (IFD) and molecular dynamic (MD) studies of 100 ns simulation time were done. Apomorphine and rotigotine showed greater non-bonding and bonding interactions with amino acids of IKKB as compared to Aripiprazole in docking studies. The IFD studies predicted improved interactions with IKKB. MMGBSA scores indicated that the complex binding free energies were favorable, and MD studies showed an acceptable root mean square deviation between protein and ligands. The protein–ligand interactions showed hydrogen bonds, water and salt bridges necessary for IKKB inhibition, as well as solvent system stability. On the protein–ligand contact map, the varying color band intensities represented the ligand’s ability to bind with amino acids. Dopamine agonists apomorphine, rotigotine, and aripiprazole were predicted to bind and inhibit IKKB in in silico system.

Published: December 2022

AbstractReal-time multisensory social interactions (RMSIs) between people are at the center of the metaverse, a new computer-mediated environment consisting of virtual “worlds” in which people act and communicate with each other in real-time via avatars. This research investigates whether RMSIs in the metaverse, when accessed through virtual-reality headsets, can generate more value for interactants in terms of interaction outcomes (interaction performance, evaluation, and emotional responses) than those on the two-dimensional (2D) internet (e.g., Zoom meetings). We combine theoretical logic with extensive field-experimental probes (which support the value-creation potential of the virtual-reality metaverse, but contradict itsgeneralsuperiority) to develop and refine a framework of how RMSIs in the metaverse versus on the 2D internet affect interaction outcomes through interactants’ intermediate conditions. The refined framework serves as foundation for a research roadmap on RMSIs in the metaverse, in which we highlight the critical roles of specific mediating and moderating forces along with interactional formats for future investigations of the metaverse and also name key business areas and societal challenges that deserve scholarly attention.
Does Social Comparison and Facebook Addiction Lead to Negative Mental Health? A Pilot Study of Emerging Adults Using Structural Equation Modelling

Published: December 2022

AbstractRecent research has observed that among the ever-increasing young users of social networking sites (e.g., Facebook), some present problematic use similar to other behavioral addictions. While regular use of Facebook is not systematically associated with mental health disorders, its addictive use has been consistently associated with higher level of depression and loneliness. Therefore, further research is needed in studying the separate impacts of regular and addictive Facebook use on young adults’ lives. The present study explored the role of Facebook addiction and social comparison on mental health and types of social networking sites (SNSs) usage (i.e., active versus passive usage), hypothesizing that addiction and social comparison will predict negative mental health outcomes and higher SNS usage. The study sample comprised 280 students at a British university. The data were analyzed using structural equation modelling to test for the significance of the relationships between these variables as well as the appropriateness of the overall hypothesised model. Results demonstrated that Facebook addiction significantly predicted depression, loneliness, and both active and passive SNS usage, and social comparison significantly predicted the level of depression significantly. The overall model also demonstrated a good fit which indicates that the hypothesized associations between the variables were strong. It is argued that the association between Facebook addiction and mental health could be a vicious cycle because no causation direction can be excluded. The implications of the study findings and future research directions are also discussed.
The Circular Experimentation Workbench – a Lean and Effectual Process
Authors: Bocken Nancy , Coffay Matthew 
Published: December 2022

AbstractCircular economy has become an important goal for companies to address climate change and pressing resource issues. Yet, the process of circular business experimentation is highly uncertain. While the lean startup has been applied to the circular experimentation process, the concept of effectuation has only been used to a limited extent, despite its potential. We investigate the following question: To what extent can lean startup and effectual thinking be combined to support the circular business model innovation process? We conducted 10 workshops where we combined these concepts with circular economy thinking. A novel process – the Circular Experimentation Workbench – was developed and evaluated to inspire participants to start experimenting with the circular economy. We found that lean startup and effectuation principles are highly complementary. Effectual questions can support the development of successful circular experiments. Our results were potentially limited by constraints related to the workshop format and action research method. Future research could build on the complementary perspectives of lean startup and effectuation to help accelerate the circular economy transition.
The distribution of lichens and mosses at Edward VII Peninsula, Marie Byrd Land, Antarctica

Published: December 2022

AbstractThis is the first detailed study of the distribution of mosses and lichens at Alexandra Mountains and Rockefeller Mountains, Edward VII Peninsula, Antarctica. A total of 418 samples was collected on 21 nunataks in the summer of 1987–1988. Lichens included 44 taxa, bringing the total known from Edward VII Peninsula to 50. Ten lichen species were new records for the Continental Antarctic zone, whilst only six were endemic to that zone. There were six species and one variety of moss, bringing the total known from Edward VII Peninsula to seven species and one variety. These included the first record of a species of Orthotrichum in Continental Antarctica. Two other species and a variety were new records for Edward VII Peninsula. Overall, the flora was species rich for a Continental Antarctic region and was comparable with the species-rich sites of Botany Bay and Kar Plateau, which are at approximately the same latitude (77°S) in southern Victoria Land. This rich flora was probably supported by a reliable summer water supply from melting snowfall and snowdrift and by the range of microenvironments at nunataks with different degrees of nutrient enrichment from nesting birds.
Coupled Urban Change and Natural Hazard Consequence Model for Community Resilience Planning

Published: December 2022

AbstractThis paper presents a new coupled urban change and hazard consequence model that considers population growth, a changing built environment, natural hazard mitigation planning, and future acute hazards. Urban change is simulated as an agent‐based land market with six agent types and six land use types. Agents compete for parcels with successful bids leading to changes in both urban land use—affecting where agents are located—and structural properties of buildings—affecting the building's ability to resist damage to natural hazards. IN‐CORE, an open‐source community resilience model, is used to compute damages to the built environment. The coupled model operates under constraints imposed by planning policies defined at the start of a simulation. The model is applied to Seaside, Oregon, a coastal community in the North American Pacific Northwest subject to seismic‐tsunami hazards emanating from the Cascadia Subduction Zone. Ten planning scenarios are considered including caps on the number of vacation homes, relocating community assets, limiting new development, and mandatory seismic retrofits. By applying this coupled model to the testbed community, we show that: (a) placing a cap on the number of vacation homes results in more visitors in damaged buildings, (b) that mandatory seismic retrofits do not reduce the number of people in damaged buildings when considering population growth, (c) polices diverge beyond year 10 in the model, indicating that many policies take time to realize their implications, and (d) the most effective policies were those that incorporated elements of both urban planning and enforced building codes.
An Ionospheric Conductance Gradient Driver for Subauroral Picket Fence Visible Signatures Near STEVE Events
Authors: Lynch Kristina A. , McManus Edward , Gutow Joshua , Burleigh Meghan , Zettergren Matt 
Published: December 2022

AbstractReported observations of picket fence signatures associated with subauroral Strong Thermal Emission Velocity Enhancement (STEVE) emission events look strikingly similar to rayed auroral curtains. Rayed auroral curtains are often the visible signatures of tearing‐mode‐unstable current sheets with precipitating auroral electron current carriers. Picket fence signatures are not located where auroral precipitation explanations apply, and are closely collocated with STEVE emission events. A similar tearing‐mode‐instability explanation can be invoked with a different source for the originating field‐aligned current (FAC) sheet. In this explanation, the FAC sheet is sourced by ionospheric conductance gradients adjacent to the localized flows of the STEVE event. Geospace Environment Model of Ion‐Neutral Interactions (GEMINI) models of the 3D ionosphere near counterstreaming STEVE‐associated flow structures show the development of sufficiently strong current sheets for tearing mode instabilities to take hold. These instabilities can locally accelerate ambient ionospheric thermal electrons to the few eV needed for the reported observed green picket fence signatures.
