Environmental Drivers of Plant Invasion in Wetland Mitigation
Authors: Hunter Dakota M. , DeBerry Douglas A. 
Published: September 2023

AbstractInvasive plant species can alter natural communities and degrade ecosystem function, yet the factors influencing species invasion are poorly understood. The purpose of this study was to characterize environmental drivers of plant community structure and invasive plant prevalence within invaded portions of wetland mitigation sites. We sampled vegetation and environmental variables (prevalence index, light availability, soil physiochemistry, site age) across invasion gradients within and adjacent to invasive plant populations at multiple wetland mitigation sites in the Coastal Plain and Piedmont physiographic provinces of Virginia (USA). Data analyses involved a multi-metric statistical approach combining correlation and CCA to arrive at a plausible model for drivers of plant community structure in the context of invasive species prevalence based on environmental correlates. We targeted populations of Arthraxon hispidus (joint-head grass), Microstegium vimineum (Japanese stiltgrass), and Typha spp. (cattail), three invasive species that are known to be problematic on wetland mitigation sites in the region. Our analyses revealed specific environmental drivers of plant community structure and invasive species prevalence associated with populations of each invader, and a few factors consistently emerged as important drivers across populations of all targeted invaders – notably, canopy cover (light availability), prevalence index (representing frequency and duration of inundation and shallow soil saturation), and a handful of physiochemical variables. The results of this research have been used to develop a suite of recommended best practices that can be implemented at the outset of a wetland mitigation project to encourage desirable wetland plant communities and reduce the risk of invasion.

AbstractThe numerical investigation of a novel subsonic thrust concept for fluidic thrust vectoring (FTV) of jet engines is the subject of this publication. FTV possibly offers advantages over conventional mechanical thrust vector control such as decreased complexity, mass and maintenance costs. The operating principle of the FTV nozzles under investigation at the Institute of Jet Propulsion is based on the Coandă effect. The applied concept of thrust vectoring uses dedicated secondary flow channels which are mounted in parallel around the nozzle inner cone or the nozzle wall. If required, bleed air, provided by extraction from the engine compressor or from an external source, is injected at a specific nozzle pressure ratio at the nozzle throat $$A_8$$

through these secondary ducts, resulting in the redirection of the secondary jet towards the convex Coandă surface. The interaction between the primary mass flow and the secondary jet leads to a redirection of the primary exhaust mass flow of the engine and thus to a vectoring of the exhaust flow. In this paper, the influence of different nozzle geometric parameters and different operating points are investigated within an extensive parametric study applied to a convergent two-dimensional thrust vectoring nozzle using computational fluid dynamics tools.

AbstractIntensive immunosuppression has enabled liver transplantation even in recipients with preformed donor-specific antibodies (DSA), an independent risk factor for graft rejection. However, these recipients may also be at high risk of progressive multifocal encephalopathy (PML) due to the comorbid immunosuppressed status. A 58-year-old woman presented with self-limited focal-to-bilateral tonic-clonic seizures 9 months after liver transplantation. She was desensitized using rituximab and plasma exchange before transplantation and was subsequently treated with steroids, tacrolimus, and everolimus after transplantation for her preformed DSA. Neurological examination revealed mild acalculia and agraphia. Cranial MRI showed asymmetric, cortex-sparing white matter lesions that increased over a week in the left frontal, left parietal, and right parieto-occipital lobes. Polymerase chain reaction (PCR) of the cerebrospinal fluid for the JC supported the diagnosis of PML. Immune reconstitution by reducing the immunosuppressant dose stopped lesion expansion, and PCR of the cerebrospinal fluid for the JC virus became negative. Graft rejection occurred 2 months after immune reconstitution, requiring readjustment of immunosuppressants. Forty-eight months after PML onset, the patient lived at home without disabling deficits. Intensive immunosuppression may predispose recipients to PML after liver transplantation with preformed DSA. Early immune reconstitution and careful monitoring of graft rejection may help improve outcomes.
Investigation of the Properties of Hydrocarbon Natural Gases Under Confinement in Tight Reservoirs Due to Critical Properties Shift
Authors: Mamdouh Mohamed , Elsayed Said K. , El-Rammah Shady 
Published: September 2023

AbstractPure components exhibit different phase behavior and critical properties shift when confined, primarily due to increased molecules-pore wall interactions. While extensive research has focused on modeling this behavior for pure components, there is a need to extend these models to hydrocarbon gas mixtures in tight and shale reservoirs to understand the deviation of gas properties from bulk behavior. The study utilizes the Peng–Robinson equation of state to calculate gas properties, considering the shift in critical properties of pure components due to confinement in EOS parameter calculations. Trend analysis investigates the effect of pore size reduction on gas properties, introducing the concepts of the confinement impact factor and specific pore radius. Correlation analysis explores the relationships between variables. Nonlinear regression analysis leads to the development of a new correlation that accounts for confinement effects on gas properties. The findings reveal that the deviation from bulk properties depends on the pore radius, pressure, temperature, and gas composition. The magnitude of deviation ranges from negligible to exceeding 15% under specific conditions of high pressure, low temperature, small pore radius, and rich gas composition. Gas viscosity experiences the most significant alteration, followed by density, while the gas compressibility factor also displays a noticeable impact. The isothermal gas compressibility coefficient demonstrates minimal to no response to confinement. Decreasing pore radius increases the gas compressibility factor, while gas viscosity and density decrease. The obtained results are crucial for shale and tight reservoir engineering calculations, particularly in adjusting gas properties in reservoir simulation and production modeling software.
A new position controller design compensating the ship motion (sinusoidal input) in the target tracking servo system
Authors: Park Ki-Woo , Park Dong-Hyuk , Kim Jae Hyung 
Published: September 2023

AbstractThis paper proposes a controller that can exhibit the good performance in a servo system where step, ramp, and sinusoidal commands are mixed. In particular, the servo system applied to the naval gun system, the laser weapon system, the electro-optical tracking system installed on the ship must be able to follow the step and ramp commands necessary for target tracking and the sinusoidal command for stabilization of the ship motion. However, in the servo systems developed so far, type I and type II can control the steady-state error of step command and ramp command to zero, but a residual error occurred in sinusoidal command. This paper proposes a new controller with zero steady-state error of sinusoidal command. Using the Park’s Transformation concept used in the current of the AC motor, a PI controller was constructed by converting the sinusoidal drive command into a synchronous frame. The control law was derived from the relationship between the stationary frame controller and the synchronous frame controller. Furthermore, to detect the frequency required for conversion, frequency detection block was proposed. Steady-state conditions were found in the control zone (fine zone) separated by the error size and verified by simulation using an example plant.
Twisted Neumann–Zagier matrices
Authors: Garoufalidis Stavros , Yoon Seokbeom 
Published: September 2023

AbstractThe Neumann–Zagier matrices of an ideal triangulation are integer matrices with symplectic properties whose entries encode the number of tetrahedra that wind around each edge of the triangulation. They can be used as input data for the construction of a number of quantum invariants that include the loop invariants, the 3D-index and state-integrals. We define a twisted version of Neumann–Zagier matrices, describe their symplectic properties, and show how to compute them from the combinatorics of an ideal triangulation. As a sample application, we use them to define a twisted version of the 1-loop invariant (a topological invariant) which determines the 1-loop invariant of the cyclic covers of a hyperbolic knot complement, and conjecturally is equal to the adjoint twisted Alexander polynomial.
The Respondent-Type Matching-to-Sample Procedure: A Comparison of One-to-Many and Linear Procedure for Establishing Equivalence Responding
Authors: Todd Jonathan , Keenan Mickey , Gallagher Stephen 
Published: September 2023

AbstractStimulus equivalence research is dominated by operant conditioning procedures that require the active responding of a participant to establish relations between arbitrary stimuli. In comparison, there has been relatively little research using respondent-type procedures, which only require the participant to view relations that appear on screen. This presentation describes two experiments using a respondent-type matching-to-sample procedure to examine the effect of the one-to-many (OTM) training procedure and the linear procedure on equivalence class formation. The OTM procedure was extremely effective in generating equivalence responding, however the linear procedure was not. These findings are discussed in the context of previous research comparing the two training procedures, as well as the effectiveness of previous respondent procedures.
Centrality in the macroeconomic multi-network explains the spatiotemporal distribution of country per-capita income
Authors: Fagiolo Giorgio , Luzzati Davide Samuele 
Published: September 2023

AbstractThis paper empirically investigates the role played by cross-country spillovers in shaping spatiotemporal differences in country income. While existing literature focused on effects captured by direct spillovers with partner countries only, here we take a complex network perspective to explore whether the global embeddedness of countries in the macroeconomic multi-network may significantly impact income, net of country local characteristics such as local foreign exposure. We employ data for the period 2000–2020 to build a time sequence of 3-layer multi graphs, with countries as nodes and links weighted by the intensity of bilateral relations in international trade, finance and human migration. Using panel-regression techniques, we then ask if country (eigenvector) centrality in the multi network can account for parts of the observed heterogeneity in country per-capita income, both cross-sectionally and over time. Robustly across a number of alternative specifications of the empirical model, we find that being more central significantly boosts country income. This implies that income-enhancing technological spillovers are not only channeled via local exposure, but also through indirect interactions with more distant nodes.
Understanding Pressures to Archaeological Heritage in the Face of Climate Change: An Integrated Approach to Coastal-Zone Assessments in Ireland
Authors: Jones Jennifer E. , Pollard Edward , Craven Kieran , Barry James , Corns Anthony , Henry Sandra , Shaw Robert , Shine Linda , Baker Louise 
Published: September 2023

AbstractCoastal heritage and archaeological sites are part of a complex system of socioenvironmental processes whose conditions are placed at risk from increasing climate-change pressures and impacts. Cultural-heritage managers are working to increase understanding of these pressures and create ways to assess, mitigate, and/or adapt to change. Coastal-zone assessments (CZA) are a recognized methodology in several national management plans to gather detailed data in order to provide an informed assessment of current resources and any associated hazards and risks. A collaborative and innovative partnership is seeking to expand on current CZA models by integrating social, historical, and geomorphological criteria into archaeological site assessment, with aims toward the development of a resource-priority index for coastal-heritage managers in Ireland.
10‐session Cognitive Behavioural Therapy (CBT-T) for Eating Disorders: A Systematic Review and Narrative Synthesis
Authors: Paphiti Andreas , Newman Emily 
Published: September 2023

AbstractTo review the literature examining the effectiveness and efficacy of a cognitive behavioural therapy (CBT) for eating disorders delivered in ten sessions for those who are not underweight (CBT-T). A systematic search of the literature (MEDLINE, EMBASE, PsycINFO, Scopus and ProQuest) was conducted to identify relevant publications to date at the time of March 2022 (re-run in May 2023). Intervention studies of any study design that investigated CBT-T offering outcome data at least pre- to post- intervention for eating disorder and related outcomes were included. Results were reported for treatment attrition, abstinence, remission, eating disorder psychopathology, disordered eating behaviours, psychosocial impairment, depression and anxiety and synthesised using a narrative synthesis framework. The Effective Public Health Practice Project (EPHPP) quality assessment tool (Thomas et al., 2004) was used to assess the quality of included studies. Outcomes for 555 people who received CBT-T across eight studies (one randomised control trial and seven non-randomised studies) were synthesised. Support was found for the effectiveness and efficacy of CBT-T for a range of non-underweight eating disorders, with respect to eating disorder psychopathology, disordered eating behaviours, psychosocial impairment, abstinence and remission. CBT-T also led to improvements for depression and anxiety symptoms. CBT-T appears to improve eating disorder and co-morbid outcomes for people with non-underweight eating disorders within ten sessions, with comparable results to standard-length CBT for eating disorders (CBT-ED). Although results for CBT-T are promising, there were concerns with the quality of the studies. Future research is required to strengthen the evidence base with larger, higher-quality studies which compare CBT-T directly with recommended psychological treatments, such as standard-length CBT-ED.
With Impressions Chosen from Another Time: Core Technologies and Debitage Production at the Lower Palaeolithic Site of Notarchirico (670–695 ka; layers F to I2)
Authors: Carpentieri Marco , Moncel Marie-Hélène , Eramo Giacomo , Arzarello Marta 
Published: September 2023

AbstractThe earliest evidence of bifaces in western Europe is dated to the initial phase of the Middle Pleistocene (la Noira, Notarchirico, Moulin Quignon, 700–670 ka), with the findings of Barranc de la Boella (1.0–0.9 Ma) considered to be an earlier local evolution. No transition assemblages are recorded during this time frame, and the “abrupt” appearance of bifaces during this time frame is associated with significant cognitive shifts in human technological behaviours (Acheulean techno-complex). The new investigations conducted at the site of Notarchirico unearthed 30 ka of repeated human occupation (695–670 ka, layers F-I2) during MIS 17, with evidence of bifacial tools in layer G (680 ka) and F along with other heavy-duty implements (LCTs, pebble tools, etc.). Massive production of debitage products realised on local raw materials collected in situ through simple and efficient core technologies characterises a large part of the lithic assemblage with a high ratio of diversified light-duty tools, including modified chert nodules. Despite core and flake assemblages being a recurrent trait of Lower Pleistocene contexts, the increase in retouched implements recorded at the onset of the Middle Pleistocene has been considered a significant technological shift. The technological analysis of the debitage products presented in this work highlights recurrent and systematic technological behaviours of the hominins of Notarchirico—who proved to efficiently overcome the raw materials dimensional constraints—even in the layers without bifaces. This may shed light on the meaning of cultural and behavioural innovation that the Acheulean techno-complex is thought to bring over Europe. It is plausible that given the substantial homogeneity of the lithic strategies within the sequence of Notarchirico, which only the “introduction” of the bifaces in the upper layers seems to interrupt, a supposed behavioural or cultural change in the site might have already occurred in the lowermost portion of the sequence. In this work, we evaluate the degree of change—if any—from a technological perspective by analysing the debitage reduction sequences.
Behind the Scenes of Co-designing AI and LA in K-12 Education
Authors: Sperling Katarina , Stenliden Linnéa , Nissen Jörgen , Heintz Fredrik 
Published: September 2023

AbstractThis article explores the complex challenges of co-designing an AI- and learning analytics (LA)-integrated learning management system (LMS). While co-design has been proposed as a human-centred design approach for scaling AI and LA adoption, our understanding of how these design processes play out in real-life settings remains limited. This study is based on ethnographic fieldwork in primary and secondary schools and employs a relational materialist approach to trace, visualise, and analyse the increasingly complex and transformative relations between a growing number of actors. The findings shed light on the intricate ecosystem in which AI and LA are being introduced and on the marketisation of K-12 education. Instead of following a rational and sequential approach that can be easily executed, the co-design process emerged as a series of events, shifting from solely generating ideas with teachers to integrating and commercialising the LMS into a school market with an already high prevalence of educational technology (EdTech). AI and LA in education, co-design and data-driven schooling served as negotiating ideas, boundary objects, which maintained connectivity between actors, despite limited AI and LA implementation and the development of a stand-alone app. Even though teachers and students were actively involved in the design decisions, the co-design process did not lead to extensive adoption of the LMS nor did it sufficiently address the ethical issues related to the unrestricted collection of student data.
The ‘Global Stocktake’ and the remaining carbon budgets for G20 countries to limit global temperature rise to +1.5 °C
Authors: Teske Sven 
Published: September 2023

AbstractThe G20 brings together the world's major economies. Its members represent 85% of global GDP, 75% of international trade, and two-thirds of the world's population. According to the Intergovernmental Panel on Climate Change, the total remaining global carbon budget required to limit the world's temperature increase to 1.5 °C (with 67% likelihood) is 400 GtCO2, decreasing to 50% likelihood if emissions reach 500 GtCO2 between 2020 and 2050. The UNFCCC's ‘Global Stocktake’ addresses the distribution of the remaining carbon budget to countries and industry sectors, to assess the technical, financial, and policy measures required for decarbonization and the national and international responsibilities involved. In this paper, the decarbonization pathways for all G20 member countries with high technical resolution, are broken down into key industry sectors. The energy-related national carbon budgets necessary to maintain the remaining global carbon budget between 400 GtCO2 and 500 GtCO2 are calculated and a new methodology how a fair distribution can be achieved, considering the historical emissions and economic situations of all G20 countries is presented.

Published: September 2023

AbstractThe study aims to compare the accuracy and reliability of tooth width measurements and Bolton ratios among plaster models (PM), cone beam computed tomography (CBCT), and intraoral scanner (IOS). This three-way comparison has not been previously conducted in existing studies. Seventy-two patients (aged 19–36) were selected from the University of Duhok clinic. PM, CBCT, and IOS images were obtained. Tooth widths and Bolton ratios were measured on plaster models and digital models (CBCT and IOS mages). Reliability was assessed by repeating all measurements after one month by the same examiner. The measurement accuracy and reliability were assessed through Repeated Measures ANOVA and ICC analysis. ICC results showed reliable measurements of tooth widths for PM, CBCT, and IOS (R = 0.90, 0.98, and 0.99 respectively). P-values for tooth widths and Bolton ratios between groups were all > 0.05. The ICC analysis revealed a strong correlation between the measurements of tooth widths and Bolton ratios obtained through the three distinct methods. PM, CBCT, and IOS can be used interchangeably in orthodontic diagnosis for accurate and reliable measurement of tooth widths and Bolton ratios (anterior and overall).
