Published: March 2024

Understanding how individual students cognitively engage while participating in small group activities in a General Chemistry class can provide insight into what factors may be influencing their level of engagement. The Interactive–Constructive–Active–Passive (ICAP) framework was used to identify individual students’ level of engagement on items in multiple activities during a General Chemistry course. The effects of timing, group size, and question type on engagement were investigated. Results indicate students’ engagement varied more in the first half of the term, and students demonstrated higher levels of engagement when working in smaller groups or subsets of larger groups when these groups contained students with similar levels of knowledge. Finally, the relation between question type (algorithmic versus explanation) and engagement depended on the activity topic. In an activity on Solutions and Dilutions, there was a significant relation where algorithmic items had higher occurrences of Interactive engagement. The implications of this work regarding teaching and research are discussed.

Examining the role of assignment design and peer review on student responses and revisions to an organic chemistry writing-to-learn assignment
Authors: Watts Field M. , Finkenstaedt-Quinn Solaire A. , Shultz Ginger V.
Published: March 2024

Research on student learning in organic chemistry indicates that students tend to focus on surface level features of molecules with less consideration of implicit properties when engaging in mechanistic reasoning. Writing-to-learn (WTL) is one approach for supporting students’ mechanistic reasoning. A variation of WTL incorporates peer review and revision to provide opportunities for students to interact with and learn from their peers, as well as revisit and reflect on their own knowledge and reasoning. However, research indicates that the rhetorical features included in WTL assignments may influence the language students use in their responses. This study utilizes machine learning to characterize the mechanistic features present in second-semester undergraduate organic chemistry students’ responses to two versions of a WTL assignment with different rhetorical features. Furthermore, we examine the role of peer review on the mechanistic reasoning captured in students’ revised drafts. Our analysis indicates that students include both surface level and implicit features of mechanistic reasoning in their drafts and in the feedback to their peers, with slight differences depending on the rhetorical features present in the assignment. However, students’ revisions appeared to be primarily connected to the peer review process via the presence of surface features in the drafts students read (as opposed to the feedback received). These findings indicate that further scaffolding focused on how to utilize information gained from the peer review process (i.e., both feedback received and drafts read) and emphasizing implicit properties could help support the utility of WTL for developing students’ mechanistic reasoning in organic chemistry.

TTMRI: Multislice texture transformer network for undersampled MRI reconstruction
Authors: Zhang Xiaozhi , Zhou Liu , Wan Yaping , Ling Bingo Wing‐Kuen , Xiong Dongping
Published: March 2024

Magnetic resonance imaging (MRI) is a non‐interposition imaging technique that provides rich anatomical and physiological information. Yet it is limited by the long imaging time. Recently, deep neural networks have shown potential to significantly accelerate MRI. However, most of these approaches ignore the correlation between adjacent slices in MRI image sequences. In addition, the existing deep learning‐based methods for MRI are mainly based on convolutional neural networks (CNNs). They fail to capture long‐distance dependencies due to the small receptive field. Inspired by the feature similarity in adjacent slices and impressive performance of Transformer for exploiting the long‐distance dependencies, a novel multislice texture transformer network is presented for undersampled MRI reconstruction (TTMRI). Specifically, the proposed TTMRI is consisted of four modules, namely the texture extraction, correlation calculation, texture transfer and texture synthesis. It takes three adjacent slices as inputs, in which the middle one is the target image to be reconstructed, and the other two are auxiliary images. The multiscale features are extracted by the texture extraction module and their inter‐dependencies are calculated by the correlation calculation module, respectively. Then the relevant features are transferred by the texture transfer module and fused by the texture synthesis module. By considering inter‐slice correlations and leveraging the Transformer architecture, the joint feature learning across target and adjacent slices are encouraged. Moreover, TTMRI can be stacked with multiple layers to recover more texture information at different levels. Extensive experiments demonstrate that the proposed TTMRI outperforms other state‐of‐the‐art methods in both quantitative and qualitative evaluationsions.

Published: March 2024

Our research is devoted to studying the possibility of using food from the larvae of black soldier flies (Hermetia illucens) (low-fat flour) in the diets of breeding roosters of the Hisex Brown cross. The inclusion of 7.5% low-fat flour in the diet structure of the roosters of the experimental group led to an increase in the quality indicators of the sperm of breeding roosters, activated metabolic processes and antioxidant protection. By the time of full physiological maturation (25 weeks), the roosters of the experimental group had a superiority (P<0.05) over the control in live weight and testes weight by 2.80 and 4.25%. An increase in ejaculate volume was found by 7.55% (P<0.05), sperm concentration by 24.36% (P<0.05), sperm survival time of up to 139 hours, while reducing the number of morphologically abnormal germ cells. A connection has been established between the amino acid and mineral compositions of the experimental feed and rooster sperm. Bioactive substances of insect larvae are able to activate enzymes of the antioxidant defense of birds. In the blood of experimental roosters, the level of glutathione peroxidase increased by 2.51% (P<0.05), superoxide dismutase - by 8.37 (P<0.01), and the amount of reduced glutathione by 12.62% (P<0.01). A decrease in oxidized glutathione by 29.67% (P<0.01) was found. The end product of fat oxidation (malondialdehyde) decreased, relative to the control, by 16.51% (P<0.01). The conducted studies have proven the effectiveness of the experimental feed in the nutrition of breeding roosters.

Obwohl ca. 20% aller Säuglinge Haltungs- und Bewegungsasymmetrien der Kopf-, Rumpf-,
und Extremitätenhaltung aufweisen, existiert keine für diesen Symptomkomplex
einheitliche Diagnose. Für einige therapeutische Herangehensweisen liegen
kontrollierte Studien vor, für andere Erfahrungsberichte. Doch welche Therapieformen
sind am besten untersucht, welche am erfolgversprechendsten? „Best Practice“ oder
Vielfalt? Eine Antwort könnte sein: „Good Practice“ mit Augenmaß.

First-principles computations reliably predict the energetics of point defects in semiconductors but are constrained by the expense of using large supercells and advanced levels of theory. Machine learning models trained on computational data, especially ones that sufficiently encode defect coordination environments, can be used to accelerate defect predictions. Here, we develop a framework for the prediction and screening of native defects and functional impurities in a chemical space of group IV, III–V, and II–VI zinc blende semiconductors, powered by crystal Graph-based Neural Networks (GNNs) trained on high-throughput density functional theory (DFT) data. Using an innovative approach of sampling partially optimized defect configurations from DFT calculations, we generate one of the largest computational defect datasets to date, containing many types of vacancies, self-interstitials, anti-site substitutions, impurity interstitials and substitutions, as well as some defect complexes. We applied three types of established GNN techniques, namely crystal graph convolutional neural network, materials graph network, and Atomistic Line Graph Neural Network (ALIGNN), to rigorously train models for predicting defect formation energy (DFE) in multiple charge states and chemical potential conditions. We find that ALIGNN yields the best DFE predictions with root mean square errors around 0.3 eV, which represents a prediction accuracy of 98% given the range of values within the dataset, improving significantly on the state-of-the-art. We further show that GNN-based defective structure optimization can take us close to DFT-optimized geometries at a fraction of the cost of full DFT. The current models are based on the semi-local generalized gradient approximation-Perdew–Burke–Ernzerhof (PBE) functional but are highly promising because of the correlation of computed energetics and defect levels with higher levels of theory and experimental data, the accuracy and necessity of discovering novel metastable and low energy defect structures at the PBE level of theory before advanced methods could be applied, and the ability to train multi-fidelity models in the future with new data from non-local functionals. The DFT-GNN models enable prediction and screening across thousands of hypothetical defects based on both unoptimized and partially optimized defective structures, helping identify electronically active defects in technologically important semiconductors.

This article focuses on the early prediction of cardiovascular disease (CVD) through the application of machine learning to health records. This study systematically reviews existing literature and employs advanced machine learning algorithms to discern predictive factors within electronic health data. Key findings highlight the significance of genetic predispositions, lifestyle choices, and clinical markers as influential contributors to CVD development. The integration of these factors into machine learning models demonstrates notable accuracy in preemptive risk assessment. The implications of this research are profound, offering potential advancements in preventive healthcare strategies, personalized interventions, and resource allocation for populations at heightened cardiovascular risk.

Published: March 2024

Objective This study aimed to describe the development and implementation of a co-designed value-based healthcare (VBHC) framework within the public dental sector in Victoria. Methods A mixed-method study was employed. Explorative qualitative design was used to examine patient, workforce and stakeholder perspectives of implementing VBHC. Participatory action research was used to bring together qualitative narrative-based research and service design methods. An experience-based co-design approach was used to enable staff and patients to co-design services. Quantitative data was sourced from Titanium (online patient management system). Results Building a case for VBHC implementation required intensive work. It included co-designing, collaborating, planning and designing services based on patient needs. Evidence reviews, value-stream mapping and development of patient reported outcomes (PROMs) and patient reported experience measures (PREMs) were fundamental to VBHC implementation. Following VBHC implementation, a 44% lower failure to attend rate and 60% increase in preventive interventions was reported. A higher proportion of clinicians worked across their top scope of practice within a multi-disciplinary team. Approximately 80% of services previously provided by dentists were shifted to oral health therapists and dental assistants, thereby releasing the capacity of dentists to undertake complex treatments. Patients completed baseline International Consortium for Health Outcomes Measurement PROMs (n = 44,408), which have been used for social/clinical triaging, determining urgency of care based on risk, segmentation and tracking health outcomes. Following their care, patients completed a PREMs questionnaire (n = 15,402). Patients agreed or strongly agreed that: the care they received met their needs (87%); they received clear answers to their questions (93%); they left their visit knowing what is next (91%); they felt taken care of during their visit (94%); and they felt involved in their treatment and care (94%). Conclusion The potential for health system transformation through implementation of VBHC is significant, however, its implementation needs to extend beyond organisational approaches and focus on sustaining the principles of VBHC across healthcare systems, policy and practice.

Objective The study examined emergency department (ED) presentations, unplanned hospitalisations and potentially preventable hospitalisations in older people receiving long-term care by type of care received (i.e. permanent residential aged care or home care packages in the community), in Australia in 2019. Methods A retrospective cohort study was conducted using the Registry of Senior Australians National Historical Cohort. Individuals were included if they resided in South Australia, Queensland, Victoria or New South Wales, received a home care package or permanent residential aged care in 2019 and were aged ≥65 years. The cumulative incidence of ED presentations, unplanned hospitalisations and potentially preventable hospitalisations in each of the long-term care service types were estimated during the year. Days in hospital per 1000 individuals were also calculated. Results The study included 203,278 individuals accessing permanent residential aged care (209,639 episodes) and 118,999 accessing home care packages in the community (127,893 episodes). A higher proportion of people accessing home care packages had an ED presentation (43.1% [95% confidence interval, 42.8–43.3], vs 37.8% [37.6–38.0]), unplanned hospitalisation (39.8% [39.6–40.1] vs 33.4% [33.2–33.6]) and potentially preventable hospitalisation (11.8% [11.6–12.0] vs 8.2% [8.1–8.4]) than people accessing permanent residential aged care. Individuals with home care packages had more days in hospital due to unplanned hospitalisations than those in residential care (7745 vs 3049 days/1000 individuals). Conclusions While a high proportion of older people in long-term care have ED presentations, unplanned hospitalisations and potentially preventable hospitalisations, people in the community with home care packages experience these events at a higher frequency.

Signal reconstruction through software processing is a crucial component of the background and signal models in the PandaX-4T experiment, which is a multi-tonne dark matter direct search experiment. The accuracy of signal reconstruction is influenced by various detector artifacts, including noise, dark count of photomultiplier, photoionization of impurities in the detector, and other relevant considerations. In this study, we presented a detailed description of a semi-data-driven approach designed to simulate a signal waveform. This work provides a reliable model for the efficiency and bias of the signal reconstruction in the data analysis of PandaX-4T. By comparing critical variables that relate to the temporal shape and hit pattern of the signals, we found good agreement between the simulation and data.

Published: March 2024

Objective. Brain-computer interfaces (BCIs) are neuroprosthetic devices that allow for direct interaction between brains and machines. These types of neurotechnologies have recently experienced a strong drive in research and development, given, in part, that they promise to restore motor and communication abilities in individuals experiencing severe paralysis. While a rich literature analyzes the ethical, legal, and sociocultural implications (ELSCI) of these novel neurotechnologies, engineers, clinicians and BCI practitioners often do not have enough exposure to these topics. Approach. Here, we present the IEEE Neuroethics Framework, an international, multiyear, iterative initiative aimed at developing a robust, accessible set of considerations for diverse stakeholders. Main results. Using the framework, we provide practical examples of ELSCI considerations for BCI neurotechnologies. We focus on invasive technologies, and in particular, devices that are implanted intra-cortically for medical research applications. Significance. We demonstrate the utility of our framework in exposing a wide range of implications across different intra-cortical BCI technology modalities and conclude with recommendations on how to utilize this knowledge in the development and application of ethical guidelines for BCI neurotechnologies.
