Published: August 2023

AbstractEfficient cleaning of contaminated water by photocatalysis has become an effective strategy in recent years due to its environmental and ecological designation. Cadmium sulfate (CdS) is an excellent photocatalyst in the visible region but has low quantum efficiency. In order to increase the photocatalytic efficiency, CdS was modified with gadolinium oxide (Gd2O3) and combined with graphene oxide (GO) nanoparticles. The estimated crystallite size (Ds) for Gd2O3, CdS/Gd2O3, and CdS/Gd2O3@GO was 29.6, 11.6, and 11.5 nm, respectively. The degradation of methylene blue (MB) reaches the highest values after 60 min under visible light irradiation with a dye concentration of (0.25 ppm). Whereas in powdered composition the efficiency of dye removal has been enhanced under UV irradiation, it reduced by increasing the MB concentration to 0.50 ppm with visible light irradiation. In addition, the CdS with/without Gd2O3 and GO were integrated into electrospun nanofibrous cellulose acetate (CA) through the electrospinning technique. The compounds of Gd2O3, CdS/Gd2O3, and CdS/Gd2O3/GO were encapsulated into CA nanofibers for the degradation of MB under visible and UV irradiation. The apparent rate constant (k) achieves a value of 0.006, 0.007, and 0.0013 min−1 while the removal efficiency reaches 41.02%, 54.71%, and 71.42% for Gd2O3@CA, CdS/Gd2O3@CA, and CdS/Gd2O3/GO@CA, respectively, after 60 min under UV irradiation.

Published: August 2023

Abstract
Purpose
Four-dimensional time-resolved phase-contrast cardiovascular magnetic resonance imaging (4D flow MRI) enables blood flow quantification in multiple vessels, which is crucial for patients with congenital heart disease (CHD). We investigated net flow volumes in the ascending aorta and pulmonary arteries by four different postprocessing software packages for 4D flow MRI in comparison with 2D cine phase-contrast measurements (2D PC).

Material and methods
4D flow and 2D PC datasets of 47 patients with biventricular CHD (median age 16, range 0.6–52 years) were acquired at 1.5 T. Net flow volumes in the ascending aorta, the main, right, and left pulmonary arteries were measured using four different postprocessing software applications and compared to offset-corrected 2D PC data. Reliability of 4D flow postprocessing software was assessed by Bland–Altman analysis and intraclass correlation coefficient (ICC). Linear regression of internal flow controls was calculated. Interobserver reproducibility was evaluated in 25 patients.

Results
Correlation and agreement of flow volumes were very good for all software compared to 2D PC (ICC ≥ 0.94; bias ≤ 5%). Internal controls were excellent for 2D PC (r ≥ 0.95, p < 0.001) and 4D flow (r ≥ 0.94, p < 0.001) without significant difference of correlation coefficients between methods. Interobserver reliability was good for all vendors (ICC ≥ 0.94, agreement bias < 8%).

Conclusion
Haemodynamic information from 4D flow in the large thoracic arteries assessed by four commercially available postprocessing applications matches routinely performed 2D PC values. Therefore, we consider 4D flow MRI-derived data ready for clinical use in patients with CHD.
Toward an interoperable, intraoperative situation recognition system via process modeling, execution, and control using the standards BPMN and CMMN

Published: August 2023

Abstract
Purpose
For the modeling, execution, and control of complex, non-standardized intraoperative processes, a modeling language is needed that reflects the variability of interventions. As the established Business Process Model and Notation (BPMN) reaches its limits in terms of flexibility, the Case Management Model and Notation (CMMN) was considered as it addresses weakly structured processes.

Methods
To analyze the suitability of the modeling languages, BPMN and CMMN models of a Robot-Assisted Minimally Invasive Esophagectomy and Cochlea Implantation were derived and integrated into a situation recognition workflow. Test cases were used to contrast the differences and compare the advantages and disadvantages of the models concerning modeling, execution, and control. Furthermore, the impact on transferability was investigated.

Results
Compared to BPMN, CMMN allows flexibility for modeling intraoperative processes while remaining understandable. Although more effort and process knowledge are needed for execution and control within a situation recognition system, CMMN enables better transferability of the models and therefore the system. Concluding, CMMN should be chosen as a supplement to BPMN for flexible process parts that can only be covered insufficiently by BPMN, or otherwise as a replacement for the entire process.

Conclusion
CMMN offers the flexibility for variable, weakly structured process parts, and is thus suitable for surgical interventions. A combination of both notations could allow optimal use of their advantages and support the transferability of the situation recognition system.
Exploring a framework for integrated STEM: challenges and benefits for promoting engagement in learning mathematics
Authors: Tytler Russell , Anderson Judy , Williams Gaye 
Published: August 2023

AbstractAdvocacy of STEM curricular approaches is based on a concern to engage students in authentic disciplinary and interdisciplinary practices in the STEM (science, technology, engineering, mathematics) disciplines, and the need to promote participation in STEM pathways. The STEM Academy professional learning program was developed to support teachers to engage and motivate students by creating real-world, challenging problems. The initiative involved interdisciplinary teams of secondary STEM teachers attending workshops and working with university experts to design, implement and evaluate STEM curricular experiences. This paper focuses on case studies undertaken in two of the twelve schools involved in the initiative, using interview data from teachers and students, to explore the nature of their programs and their experiences. We investigate key features of these two schools’ approaches, using a conceptual framework for integrated STEM, and explore the challenges and benefits of different features of integrated STEM that promote different dimensions of engagement in learning mathematics. We explore how the framework characteristics can be reframed into four dimensions that promote mathematics engagement in integrated STEM education - design thinking in authentic contexts, content integration, STEM practices and 21st Century skills, and exposure to professional practice.
GREM1 signaling in cancer: tumor promotor and suppressor?
Authors: Gao Zhichun , Houthuijzen Julia M. , ten Dijke Peter , Brazil Derek P. 
Published: August 2023

Abstract
GREMLIN1 (GREM1) is member of a family of structurally and functionally related secreted cysteine knot proteins, which act to sequester and inhibit the action of multifunctional bone morphogenetic proteins (BMPs). GREM1 binds directly to BMP dimers, thereby preventing BMP-mediated activation of BMP type I and type II receptors. Multiple reports identify the overexpression of GREM1 as a contributing factor in a broad range of cancers. Additionally, the GREM1 gene is amplified in a rare autosomal dominant inherited form of colorectal cancer. The inhibitory effects of GREM1 on BMP signaling have been linked to these tumor-promoting effects, including facilitating cancer cell stemness and the activation of cancer-associated fibroblasts. Moreover, GREM1 has been described to bind and signal to vascular endothelial growth factor receptor (VEGFR) and stimulate angiogenesis, as well as epidermal and fibroblast growth factor receptor (EGFR and FGFR) to elicit tumor-promoting effects in breast and prostate cancer, respectively. In contrast, a 2022 report revealed that GREM1 can promote an epithelial state in pancreatic cancers, thereby inhibiting pancreatic tumor growth and metastasis. In this commentary, we will review these disparate findings and attempt to provide clarity around the role of GREM1 signaling in cancer.

Does mindfulness improve one’s affective state? Temporal associations between trait mindfulness and positive and negative affect
Authors: Jose Paul E. , Geiserman Anna 
Published: August 2023

AbstractAlthough cross-sectional and daily diary studies have noted associations among trait mindfulness and positive and negative affect, lacking are studies that longitudinally examine these relationships over a period of months. We tested whether trait mindfulness (assessed with the Five Facet Mindfulness Measure) predicted an increase in positive affect and a decrease in negative affect across 3 months. A sample of 319 community adults completed self-report measures of mindfulness, positive affect, and negative affect at three times of measurement separated by three months each. As hypothesised, overall mindfulness, tested with a random intercepts cross-lag path model, predicted over three months a decrease in negative affect, but, contrary to predictions, did not predict an increase in positive affect. In the reverse direction, within-subject negative affect predicted decreases of overall within-subject mindfulness, which suggests that this relationship may be reciprocal over time. When examined at the facet level of mindfulness, all five within-subject facets of the FFMQ predicted reductions in within-subject negative affect over time. In return, within-subject negative affect predicted reductions in three within-subject mindfulness facets: non-reacting, acting with awareness, and describing. On balance, the results of this study suggest that trait mindfulness, as assessed with the FFMQ, was much more successful in predicting diminished negative affect than in predicting a boost in positive affect. Further, the presence of negative affect seems to exert an inhibiting influence over time on the implementation of several mindfulness facets.
Why Won’t You Listen To Me? Predictive Neurotechnology and Epistemic Authority
Authors: Tacca Alessio , Gilbert Frederic 
Published: August 2023

AbstractFrom epileptic seizures to depressive symptoms, predictive neurotechnologies are used for a large range of applications. In this article we focus on advisory devices; namely, predictive neurotechnology programmed to detect specific neural events (e.g., epileptic seizure) and advise users to take necessary steps to reduce or avoid the impact of the forecasted neuroevent. Receiving advise from a predictive device is not without ethical concerns. The problem with predictive neural devices, in particular advisory ones, is the risk of seeing one’s autonomous choice supplanted by the predictions instead of being supplemented by it. For users, there is a potential shift from being assisted by the system to being over-dependent on the technology. In other terms, it introduces ethical issues associated with epistemic dependency. In this article, we examine the notion of epistemic authority in relation to predictive neurotechnologies. Section 1 of our article explores and defines the concept of epistemic authority. In section 2, we illustrate how predictive devices are best conceived of as epistemic authorities and we explore the subject-device epistemic relationship. In section 3, we spell out the risk of harms interconnected with epistemic deferral. We conclude by stressing a set of preliminary measures to prepare users for the authoritative nature of predictive devices.
Smoking at the Intersections of Race/Ethnicity and Sexual Orientation

Published: August 2023

AbstractResearch has tended to document smoking disparities separately by race/ethnicity and sexual orientation, with relatively less work examining the intersections of both identities. As such, we draw on data from the 2010 Social Justice Sexuality Project to demonstrate how cigarette smoking disparities manifest across detailed intersections of race/ethnicity and sexual orientation among a sample of U.S. adults. Findings from logistic regression models that adjust for demographic, socioeconomic, and social support confounders across groups reveal that risk of current cigarette smoking tends to distribute multiplicatively across identity groups. For example, findings show that racial/ethnic minority adults do not have equally lower likelihood of current cigarette smoking compared to white adults among heterosexual adults. Furthermore, while sexual minority adults generally have a higher likelihood of current cigarette smoking relative to their heterosexual counterparts, their levels of risk are not uniformly shared but instead are critically shaped by race/ethnicity. Overall, results underscore the need to consider both within- and between-group differences in assessments of health inequities across identity categories.

Published: August 2023

AbstractIn the framework of CleanSky2’s Airframe project DA9, engine tonal noise is a cooperation between Dassault Aviation and DLR. The project aims to enhance the understanding and mitigation of engine-related tonal noise in the aircraft cabin. The presented work was done to get an in-depth understanding of the vibroacoustic behavior of DLR’s Falcon 2000LX ISTAR aircraft. A two and a half weeks long vibroacoustic ground test was conducted utilizing artificial shaker excitation and operational engine excitation. The responses were measured using a roving grid of accelerometers at more than 1200 positions, meaning a subset of about 250 sensors were installed at every given time and then moved along the fuselage in a predetermined way to get a high-resolution measurement of aircrafts fuselage. The accelerometer data were than processed to show operational deflections shapes and calculate experimental structural intensity vector fields to analyze the energy transfer through the structure for optimized placement of active or passive counter measures. Specifically, the transport of tonal frequencies generated by the engines was analyzed.
Towards an Indigenous literature re-view methodology: Aboriginal and Torres Strait Islander boarding school literature
Authors: Rogers Jessa 
Published: August 2023

AbstractThis paper outlines the development of a new Indigenous research methodology: Indigenous Literature Re-view Methodology (ILRM). In the rejection of the idea that Western, dominant forms of research ‘about’ Indigenous peoples are most valid, ILRM was developed with aims to research in ways that give greater emphasis to Indigenous voices and knowledges, foregrounding Indigenous ways of being, doing and knowing. The advantages of ILRM include identifying themes as ‘relevant’ as opposed to ‘common’. This method is based on relatedness, which is framed by Aboriginal ontology, axiology and epistemology, or ways of being, ways of doing and ways of knowing. Describing and employing ILRM to re-view Indigenous Australian boarding school literature, it was found there is a modest but robust body of research that has emerged in the past 20 years. Sixty-six written sources (i.e. journal articles, reports, theses and books) which were published in 2000 onwards and focussed on a topic of contemporary Indigenous boarding schooling were analysed. Sources that included a chapter or section on boarding as part of a publication focussed on other topics were not included in this re-view. Seven major themes emerged, including home, student experience, transitions, access, staff, health and evaluation. This paper focusses on the development and use of ILRM as an Indigenous methodology for researchers in Indigenous fields of study.
Uniform instruction set extensions for multiplications in contemporary and post-quantum cryptography

Published: August 2023

AbstractHybrid key encapsulation is in the process of becoming the de-facto standard for integration of post-quantum cryptography (PQC). Supporting two cryptographic primitives is a challenging task for constrained embedded systems. Both contemporary cryptography based on elliptic curves or RSA and PQC based on lattices require costly multiplications. Recent works have shown how to implement lattice-based cryptography on big-integer coprocessors. We propose a novel hardware design that natively supports the multiplication of polynomials and big integers, integrate it into a RISC-V core, and extend the RISC-V ISA accordingly. We provide an implementation of Saber and X25519 to demonstrate that both lattice- and elliptic-curve-based cryptography benefits from our extension. Our implementation requires only intermediate logic overhead, while significantly outperforming optimized ARM Cortex M4 implementations, other hardware/software codesigns, and designs that rely on contemporary accelerators.

Published: August 2023

AbstractAgriculture faces potentially competing societal demands to produce food, fiber and fuel while reducing negative environmental impacts and delivering regulating, supporting and cultural ecosystem services. This necessitates a new generation of long-term agricultural field experiments designed to study the behavior of contrasting cropping systems in terms of multiple outcomes. We document the principles and practices of a new long-term experiment of this type at Rothamsted, established at two contrasting sites in 2017 and 2018, and report initial yield data at the crop and system level. The objective of the Large-Scale Rotation Experiment was to establish gradients of system properties and outcomes to improve our fundamental understanding of UK cropping systems. It is composed of four management factors—phased rotations, cultivation (conventional vs reduced tillage), nutrition (additional organic amendment vs standard mineral fertilization) and crop protection (conventional vs smart crop protection). These factors were combined in a balanced design resulting in 24 emergent cropping systems at each site and can be analyzed at the level of the system or component management factors. We observed interactions between management factors and with the environment on crop yields, justifying the systems level, multi-site approach. Reduced tillage resulted in lower wheat yields but the effect varied with rotation, previous-crop and site. Organic amendments significantly increased spring barley yield by 8% on average though the effect again varied with site. The plowed cropping systems tended to produce higher caloric yield overall than systems under reduced tillage. Additional response variables are being monitored to study synergies and trade-offs with outcomes other than yield at the cropping system level. The experiment has been established as a long-term resource for inter-disciplinary research. By documenting the design process, we aim to facilitate the adoption of similar approaches to system-scale agricultural experimentation to inform the transition to more sustainable cropping systems.

Potential of Multi-temporal InSAR for Detecting Retrogressive Thaw Slumps: A Case of the Beiluhe Region of the Tibetan Plateau

Published: August 2023

AbstractPermafrost degradation due to climate warming is severely reducing slope stability by increasing soil pore water pressure and decreasing shear strength. Retrogressive thaw slumps (RTSs) are among the most dynamic landforms in permafrost areas, which can result in the instability of landscape and ecosystem. However, the spatiotemporal characteristics of surface deformation of RTSs are still unclear, and the potentials of deformation properties in mapping large-scale RTSs need to be further assessed. In this study, we applied a multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR) method to map the spatiotemporal variations in surface deformation of RTSs in the Beiluhe region of the Tibetan Plateau by using 112 scenes of Sentinel-1 SAR data acquired from 2017 to 2021. The deformation rates of RTSs ranged from − 35 to 20 mm/year, and three typical motion stages were inferred by analyzing the deformation variation trend of the headwall of RTSs: stable, abrupt thaw, and linear subsidence. A total of 375 RTSs were identified in the Mati Hill region by combining InSAR-based deformation results with visual interpretation of optical remote sensing images. Among them, 76 RTSs were newly developed, and 26% more than the inventory derived from the optical images alone. This study demonstrated that the combination of InSAR-derived deformation with optical images has significant potential for detecting RTSs with high accuracy and efficiency at the regional scale.

Published: August 2023

Abstract
Purpose of Review
Traditionally, electric grid planning aims to maintain safe, reliable, efficient, and affordable service. As policies, societal goals, and technologies evolve, new objectives for power system planners emerge, creating a need for system performance benchmarking of these objectives.

Recent Findings
With a focus on resilience and energy equity as emerging grid objectives, this review provides an overview of emerging trends in resilience and energy equity metrics, current examples of their coupling in grid planning, and observations on both metric trajectories.

Summary
The simultaneous development of resilience and energy equity metrics reveals common themes relating to the scale of measurement, the use of socioeconomic inputs, a departure from utility-controlled metrics, and the need for broader stakeholder inclusion in decision-making processes. This work presents a timely discussion of the essential nature of metrics for grid planners as equity and resilience policies and goal transition from abstract objectives to accountability mechanisms and real dollar investments.
