Paradigm or Practice? Situating GIS in contemporary archaeological method and theory
Authors: Ullah Isaac I. , Clow Zachery , Meling Juliette 
Published: February 2023

Abstract
Geographic Information Systems (GIS) has been used in archaeology for four decades, and colloquially appears to have become a main tool in the geospatial aspects of archaeological practice. In this paper, we examine temporal trends in the use and/or mention of GIS in archaeological publications (books and journal articles), conference presentations, and websites. We gathered data through keyword searches and with formal sampling surveys and conducted both quantitative and qualitative analyses to characterize the changing nature and intensity of GIS use in archaeology over time. We show how archaeological GIS-use has grown from a few early adopters of the 1980’s, through a slow initial integration phase in the 1990’s, to a punctuated set of two major expansions in the 2000’s and 2010’s. While we find that basic use of GIS has grown to the point where it can be considered ubiquitous – if not universal – in the discipline, we also discovered that the major focus in archaeological GIS advancement is methodological rather than theoretical. We provide a historical context to this temporal pattern and identify five roadblocks that we believe have hampered the development of a theory-rich archaeological GIS: 1) deficiencies in the archaeological GIS education model, 2) over-reliance on commercial software, 3) technical/technological barriers, 4) gaps in acceptance of GIS, and 5) the perception of GIS as “just a tool.” We offer initial suggestions for ways forward to mitigate the effects of these roadblocks and build a more robust, theoretically sophisticated relationship with GIS in archaeology.

Abstract
Study design:
Descriptive
Objectives
The primary objective is to describe the intervention that will be provided in a large multi-centre randomised controlled trial (RCT) titled: Early and Intensive Motor Training for people with Spinal Cord Injuries (the SCI-MT Trial). The secondary objective is to describe the strategies that will be used to operationalise and standardise the Motor Training provided to participants while keeping the intervention person-centred.
Methods
The paper focuses on the rationale and principles of Motor Training for people with spinal cord injuries (SCI). The description of the intervention is based on the Template for Intervention Description and Replication (TIDieR) checklist. Specifically, it addresses the following 6 criteria of the TIDieR checklist: why the effectiveness of Motor Training is being examined; what, how, where and when the Motor Training will be administered; and how much Motor Training will be provided.
Results
A detailed intervention manual has been developed to help standardise the delivery of the intervention.
Conclusions
This paper describes the details of a complex intervention administered as part of a large randomised controlled trial. It will facilitate the subsequent interpretation of the trial results and enable the intervention to be reproduced in clinical practice and future trials.
Reimaging the unimaginable: Moving an on-campus health course online during COVID-19

Abstract
In early 2020 the world experienced the one in 100-year COVID-19 pandemic, causing major disruption to higher education in Australia. In Victoria, Australia this necessitated a rapid shift of university teaching and placements to the online environment. For health programs in particular, which are typically taught with significant on-campus and face to face components, this shift online created major changes in both teaching and learning. This study sought to explore the lived experience of teaching and learning for Australian occupational therapy students and academics at one Australian university during COVID-19. More specifically, this study aimed to explore the facilitators and barriers to occupational therapy online teaching and learning and the impacts it had on student/academic roles, professional identity, motivation and wellbeing. A qualitative phenomenological approach was adopted, with semi-structed interviews conducted with students (n = 10) and academics (n = 6). Inductive, thematic analysis of data was utilised. Five key themes were identified from the analysis of data: impact on professional identity, disruption of roles, feeling pressure, mutual respect and gratitude, and the importance of social connection at university. Whilst online learning may be more flexible for students and more cost effective for universities, the findings of this study suggest that there is a need to provide continued opportunities for health students to engage with academics and each other on-campus.

Abstract
Chemical insecticides have long been considered means of controlling crop pests. Although their effectiveness is obvious, their impact on the environment is increasingly discussed.. The objective of this study is to determine the agro-ecological component of a biological insecticide based on Aloe Vera in a Sahelian context. For this, an experimental device (randomized complete block with 3 repetitions and 4 block treatments) was set up to experiment with Aloe barbadensis as a bio insecticide on okra pests, so the data was collected through a grid. observation and monitoring of parameters. he results obtained show that the level of damage is significantly high in the control treatment T0 (63%) compared to the other treatments, i.e. 29% for the treatment T1, 7% for T2 and 1% for T3. Furthermore, as regards the number of leaves, 4 leaves attacked out of 6 were recorded at treatment T0, 1 leaf attacked out of 9 at treatment T1 and 0 leaves attacked at treatment T2 and T3. Thus, we can say that the pests were more dominant in the control T0 on all the parameters studied than in the other treatments and the results were negative in all the control treatments (T0). On this, aloe Barbadensis formulated as a biological insecticide in this experiment was found to be very effective against okra pests.

Published: February 2023

Abstract
Background: To investigate the risk of psychiatric disorder development in term-born children with marginally low birth weight (MLBW, 2000–2499 g).
Methods: This is a nationwide retrospective cohort study, by analysing the data from Taiwan’s National Health Insurance Research Database from 2008 to 2018. The study population includes propensity-score-matched term-born infants with MLBW and those without MLBW (birth weight ³ 2500 g). Cox proportional hazard analysis was used after adjustment for potential demographic and perinatal comorbidity confounders. Incidence rates and hazard ratios (HR) of 11 psychiatric diagnoses were evaluated.
Results: A total of 53,276 term-born MLBW infants and 1,323,930 term-born infants without MLBW were included in the study. After propensity score matching for demographic variables and perinatal comorbidities, we determined that the term-born MLBW infants (n = 50,060) were more likely to have specific developmental delays (HR = 1.38, 95% confidence interval (CI) [1.33, 1.43]), attention deficit and hyperactivity disorder (HR = 1.26, 95% CI [1.20, 1.33]), autistic spectrum disorder (HR=1.26, 95% CI [1.14, 1.40]), conduct disorder (HR =1.25, 95% CI [1.03, 1.51]), and emotional disturbance (HR: = 1.13, 95% CI: [1.02, 1.26]) than did the term-born infants without MLBW (n = 50,060).
Conclusion:MLBW was significantly associated with the risk of subsequent psychiatric disorder development among term-born infants. The study findings demonstrate that further attention to mental health and neurodevelopment issues may be necessary in term-born children with MLBW. However, possibilities of misclassification in exposures or outcomes, and risks of residual and unmeasured confounding should be concerned when interpreting our data.
Solving Sparse Reward Tasks Using Dynamic Range Shaped Rewards
Authors: Kong Yan , Wei Junfeng 
Published: February 2023

Abstract
While approaches to shaping rewards in solving sparse reward tasks are beneficial, their successful application usually does not consider the problem of environment size, which remains a challenging task in larger-scale environments where the state space is too large. For example, in tasks where the intelligence must achieve a certain goal state, it is often difficult for the intelligence to reach the goal when the environment is large enough to be rewarded and learn many useless episode experiences, resulting in longer training times and compromised performance. We introduce a simple and effective model-free approach to learning to shape the distance-to-goal reward for failure in tasks that require successful goal attainment. Our approach introduces a dynamic range on the goal, with an associated reward function set according to the range to guide the correct goal direction. This approach is much less affected by state space oversizing in larger-scale environments and can solve sparse reward tasks quickly and efficiently. In our experiments, we demonstrate that our approach successfully solves goal-directed tasks of different sizes, but in these tasks, other now popular reinforcement learning algorithms, which are based on the rewards of naive distance shaping failure rollout, are more influenced by the size of the environment, resulting in poorer performance in larger scale environments.

Published: February 2023

Abstract
Sensing human activities through wireless technology is the key to human-computer interaction. Relevant studies show that millimeter-wave radar has attracted more and more attention because it can accurately measure distance, velocity, and angle, and extract 3D point cloud images. However, the millimeter-wave point cloud is very sparse. For example, the depth neural network of PointNet is designed to deal with the LIDAR point cloud, which is not effective on the millimeter-wave radar point cloud. Therefore, in this paper, we propose a user activity perception system mmBheavior based on commercial millimeter-wave radar chip. Firstly, we use an improved clustering algorithm P-DBSCAN, which overcomes the problem of DBSCAN parameter sensitivity and realizes adaptive user target detection in the environment of changing number of people. Then we propose a new neural network architecture P-BiLSTMNet, which improves PointNet + + and introduces BiLSTM to learn the time dependence of point cloud. Experiments show that the system can classify all kinds of motion, and the accuracy is more than 93%.
Assessment of subtle cardiac dysfunction induced by premature ventricular contraction using two dimensional strain echocardiography and the effects of successful ablation
Authors: Doğan Zeki , Erden Emine Çakcak , ERDEN İsmail , Bektaşoğlu Gökhan 
Published: February 2023

Abstract
Background: We aimed to evaluate the effects of successful ablation on impaired left ventricular global longitudinal strain (LV-GLS) in patients with frequent premature ventricular contractions (PVCs). We also evaluated the potential risk factors of impaired LV-GLS.
Methods: Thirty-six consecutive patients without any structural heart disease who were treated with radiofrequency (RF) ablation because of frequent PVCs were included into the study. All patients were evaluated with standard transthoracic and two-dimensional speckle tracking echocardiography (2D-STE).
Results: The mean LVGLS values before ablation were 17.3±3.7. This value was observed as 20.5±2.6 after ablation and the difference was statistically significant (p<0.01). Patients were categorized into 2 groups in the form of those having LV-GLS value >-16% and ≤16%. Low PVC E flow/post-PVC E flow and PVC SV/post-PVC SV ratios were associated with impaired LV-GLS.
Conclusion: In symptomatic patients with frequent PVCs and normal left ventricular ejection fraction (LVEF), we observed significant improvement in LV-GLS value following successful RF ablation. Patients with impaired LV-GLS more often display nonejecting PVCs and postextrasystolic potentiation (PEP) compared to patients with normal LV-GLS.
Depression wetland formation by redox-driven iron and silica cycling

Published: February 2023

Abstract
This paper investigates the origin and geomorphic evolution of Shadow Vlei, a depression wetland located approximately 30 km northwest of Port Elizabeth. The wetland is on sandstone on the African Erosion Surface. The depression wetland has a rim of high-lying ground surrounding a central depression. Fluctuations between wet and dry periods create both highly reducing conditions in soils during wet phases in the depression, and highly oxidising conditions in the depression margin. Under reducing conditions, iron(III) oxides that are insoluble, are reduced to soluble iron(II), which is transported to and trapped in the margins of the depression under oxidising conditions when the water table declines and iron(II) is oxidised to iron(III). There is also a moderate flux of silica from the surface in the centre of the depression to the margins, which is suggested to be associated with maximum alkalinity associated with iron(III) reduction, and decreased alkalinity in the margins associated with iron(II) oxidation. However, the main flux of silica is from the surface in the centre of the depression to depth of greater than 1.5m, again associated with variations in pH linked to iron-cycling. These reactions have thus caused a net volume loss in the centre of the depression, causing sagging, and a net volume gain at the margins of the depression, causing swelling. Wetland formation associated with alteration of landform morphology as a consequence of alternating redox conditions represents a novel mechanism that has not yet been described.
Porous Bleed Boundary Conditions for Supersonic Flows with &amp; without Shock-Boundary Layer Interaction
Authors: Giehler Julian , Grenson Pierre , Bur Reynald 
Published: February 2023

Abstract
In this paper, several existing porous bleed models are implemented intothe in-house RANS-solver elsA, and their performance are evaluated ontwo different flow cases. Reference simulations are performed to evalu-ate the accuracy of the applied bleed models and to show the lack ofmodeling different plate geometries. The models significantly differ inpredicting the bleed mass flux along the plate. For the turbulent super-sonic boundary layer bleeding, the reference simulations demonstrate ahole diameter influence on the flow, but none of the models considersthis effect. The model of Slater fits well with the reference simulationby applying it to its extracted data. However, applying the bleed mod-els as a boundary condition results in more significant deviations fromthe reference simulation, leading to an overestimation of the wall shearstress and fuller boundary layer profiles downstream of the bleed region.Additionally, in the second flow case, including the shock-boundary layerinteraction, the effect of the porous bleed is overestimated. No modelis found suitable for a shock-boundary layer interaction control, andessential parameters such as the bleed hole diameter are not considered.

Abstract
Background
Diabetes with co-existing bone fragility or osteoporosis is common in elderly patients, whereas is frequently underestimated.
Methods
We conducted dual-energy x-ray absorptiometry (DXA) with 7-site skinfold (SF) and dominant hand grip strength measurements among patients with type 2 diabetes (T2DM) to assess their gender-specific associations. A total of 103 patients with T2DM (60 females and 43 males), aged between 50–80 years (median 68.0 years) were enrolled.
Results
Our results revealed osteoporosis was negatively correlated with grip strength in both genders, negatively correlated with lean mass solely in males and negatively correlated with fat mass (particular the gynoid fat mass and thigh SF thickness) in females. Via performing multivariable stepwise logistic regression, we identified grip strength in both genders and thigh SF thickness in females as predictors for osteoporosis. Receiver operating characteristic curve analysis further disclosed 20.5 mm female thigh skinfold thickness, 18.1 kg female grip strength and 29.0 kg male grip strength as reasonable cutoff levels for predicting osteoporosis in the Taiwanese patients with T2DM.
Conclusions
Patients with T2DM presented gender-specific associations between osteoporosis, body composition and grip strength. Grip strength and thigh SF thickness might serve as predictors for early detection of osteoporosis in patients with T2DM.
Bell state measurement locally explained
Authors: Muchowski Eugen 
Published: February 2023

Abstract
Entangled quantum systems can connect to the environment by means of a Bell state measurement. This is true for instance for teleportation and entanglement swapping. While the results are well understood it is not quite clear if they involve nonlocal action or if they are determined in advance. Models based on the fact that the partners of an entangled pair have the same value of a statistical parameter do not apply here. Therefore, in this work a model is presented which reproduces the quantum mechanical predictions for expectation values with spin measurements, but is not based on shared statistical parameters. The coupling of the entangled particles is instead based on the conservation of the spin angular momentum. The model refutes Bell's theorem and explains teleportation and entanglement swapping in a local manner as well. Multilevel entanglements can also be explained locally by the model. The manuscript is thus a step forward towards a complete theory describing quantum physical reality as thought possible by Einstein, Podolsky and Rosen.

Published: February 2023

Abstract
In this note, we introduce a new approach to abstract "synthetic" projective lines. We discuss various aspects of our approach, and compare these aspects
with the classical one. A number of intriguing questions arise. Amongst these aspects, we discuss geometric closures, and introduce automorphism-blocking sets. We also construct a number of (counter) examples in infinite cases.
Recurrent, life-threatening PE in the setting of popliteal vein aneurysm in pregnancy: A case report
Authors: McBride S. Ainslie , Rannelli Luke A. , Cantle Paul M. 
Published: February 2023

Abstract
Background
Popliteal vein aneurysms (PVA) are a rare clinical entity with unknown etiology that pose a significant risk for venous thromboembolic events (VTE). The current literature supports anticoagulation and operative management. There are few case reports of PVA in pregnancy. We present a unique case of a pregnant patient with recurrent pulmonary embolism (PE) in the setting of PVA with intra-aneurysmal thrombosis who ultimately underwent surgical excision.
Case presentation
A previously healthy 34-year-old G2P1 at 30 weeks gestational age presented to the emergency department with shortness of breath and chest pain. She was diagnosed with PE and subsequently required intensive care unit (ICU) admission and thrombolysis for a massive PE. While on a therapeutic dose of tinzaparin she had recurrence of PE in the post-partum period. She was treated with supratherapeutic tinzaparin and subsequently transitioned to warfarin. She was found to have a PVA and ultimately underwent successful aneurysmorrhaphy. She remains on anticoagulation for secondary prevention of VTE.
Conclusions
PVA are a rare but potentially fatal source of VTE. Patients most commonly present with symptoms of PE. The risk of VTE is elevated in the pro-thrombotic states of pregnancy and the post-partum period due to both physiologic and anatomical changes. The
recommended management of PVA with PE is anticoagulation and surgical resection of the aneurysm, however this can be complicated in the setting of pregnancy. We demonstrated that pregnant patients with PVA can be temporized with medical management to avoid surgical intervention during pregnancy, but require close symptom monitoring and serial imaging to reassess the PVA, with high index of suspicion for recurrent VTE. Ultimately, patients with PVA and PE should undergo surgical resection to reduce the risk of recurrence and long-term complications. The ideal duration of post-operative anticoagulation remains unclear, and should likely be decided on based on risks, benefits, values, and shared decision making with the patient and their care provider.
