AbstractFlowing an electrical current that is both of high areal density and large spin polarization across a magnetic tunnel junction (MTJ) can, through spin-transfer torque (STT), alter the relative magnetic orientation of the MTJ’s ferromagnetic electrodes. This effect has enabled key next-generation MTJ applications and commercialized products, from memories to artificial synapses and energy harvesters. As MTJs are now downscaled to 2 nm, basic experimental data challenge the accepted understanding of their operation. From transport spectroscopy, ferromagnetic resonance experiments and ab-initio calculations it is revealed that the high conductivity of STT-ready MTJs, and the STT effect therein, is mediated by oxygen vacancy complexes within the MgO barrier. Our work positions the oxygen vacancy at the core of MgO spintronics. This should disrupt the status-quo on STT-MRAM R&D, by generating defect-specific research and new ideas to confer additional functionality to these next-generation electronic devices, as a nanoelectronics platform to industrialize quantum physics.

Published: January 2025

AbstractCross-income-level collaboration (CILC) is crucial for developing global health approaches that benefit low- and middle-income countries (LMICs). Multiple myeloma (MM) is a representative example of a complex, understudied disease in sub-Saharan Africa (SSA). Based on publications, we developed a network analysis tool to assess scientific collaborations. Here, we present findings from a systematic analysis of publications retrieved from PubMed between January 2002 and June 2022. We evaluated individual institutional contributions and collaboration patterns using undirected weighted networks. Our findings reveal that intra-income-level collaborations dominate MM research in SSA, with high-income countries (HICs) primarily engaging with a few local institutions, mainly in South Africa and Nigeria. Increasing CILC is essential to advance research in this area. Our analysis tool provides insights into the collaboration strength, highlights gaps in the field and identifies leading institutions, ultimately aiming to support the development of more effective international collaboration and research strategies.
Speech-Language Pathology Students' Perception of Learning Anatomy and Physiology via 3D-Printed Models
Authors: Ofoe Levi C. 
Published: January 2025

Purpose:
This study examined the learning experiences of speech-language pathology students after creating three-dimensional (3D) anatomical models as part of an undergraduate Anatomy and Physiology course.

Method:
A total of 44 undergraduate students used 3D software programs to design anatomical components (e.g., larynx, brainstem, brain cortex, ear, or mouth) relevant to speech-language pathology. Subsequently, 40 (90.9%) students completed a questionnaire regarding their learning experiences.

Results:

The data revealed that most students (60%) reported no prior experience with 3D designs. However, subsequent analyses indicated that a greater proportion of the students perceived a more positive learning experience about anatomy (82.5%), physiology (72.5%), and disorders (72.5%) as related to their model compared to those who did not perceive a positive learning experience. Additionally, students who preferred a kinesthetic learning style expressed higher satisfaction with their anatomical models (
p
= .02) than those who indicated an auditory learning style.

Conclusion:
The findings suggest that integrating 3D designs into the Anatomy and Physiology curriculum of speech-language pathology programs could provide students with a more positive learning experience related to anatomical concepts and their related disorders.
Translanguaging in AACtion: An Expansive Approach to Multimodal Communication With Augmentative and Alternative Communication Users
Authors: Saechao Karina R. , Privette Chelsea , Kim John 
Published: January 2025

Purpose:
The purpose of this framework is to challenge the deficit perspectives toward multimodal communication and to encourage speech therapists and classroom teachers to apply educational justice and equity practices with modally marginalized individuals in education and clinical practice.

Method:
We summarize contemporary challenges in augmentative and alternative communication (AAC) as a practice area and integrate translanguaging and crip linguistics literature to propose a novel framework: Translanguaging in AACtion.

Results:
The authors propose the Translanguaging in AACtion framework to provide a praxis for engaging with and supporting all language users in and beyond the classroom by rethinking service delivery, supporting reciprocal engagement, and letting students language. The Translanguaging in AACtion framework guides speech therapists toward supporting disabled nonspeaking individuals to use their full-bodied semiotics (modes, languages, and dialects) in every setting, with every person, in every situation.

Conclusions:
This work highlights the languaging practices of (dis)abled, nonspeaking language users. Next steps are suggested to support speech therapists and classroom teachers with rethinking their praxis, with a focus on AACtion.

Authors: Lee Sue Ann S. , Winkelman Logan , Hooper Troy L. 
Published: January 2025

Purpose:
While the significance of emotional intelligence (EI) for health care providers has been recognized in various health care fields, its importance is not fully understood in the discipline of communication sciences and disorders (CSD). The purpose of this study was to investigate the perspectives on EI among students, practitioners, and faculty members to identify the current level of EI in the discipline of CSD.

Method:
A total of 825 CSD students, practitioners, and faculty members in the United States completed an online survey. The survey consisted of 42 questions including participants' demographic information, the current level of EI exposure, and training EI concepts along with their perception, attitude, and perceived usefulness of EI. The relevance of EI to clinical practice and personal life as well as the needs for EI training programs in the CSD discipline were also asked. Multiple chi-square analyses were conducted to examine whether the percentage of responses on each question was significantly different among students, practitioners, and faculty members.

Results:
The results of this study suggested CSD students, practitioners, and faculty members surveyed had a foundational understanding of EI concepts, perceived EI concepts to be useful personally and professionally, and have positive attitudes toward developing their skillset in the area of EI.

Conclusions:
Our data suggested continued efforts be made toward providing EI training for CSD students and practitioners to enhance professional development and patient outcomes. Being the first examination of CSD professional perspectives on EI, the study provides a useful resource in developing curriculum and continuing education programs for students, faculty, and practitioners in various health care fields.
MMF‐Net: A novel multi‐feature and multi‐level fusion network for 3D human pose estimation
Authors: Li Qianxing , Kong Dehui , Li Jinghua , Yin Baocai 
Published: January 2025

AbstractHuman pose estimation based on monocular video has always been the focus of research in the human computer interaction community, which suffers mainly from depth ambiguity and self‐occlusion challenges. While the recently proposed learning‐based approaches have demonstrated promising performance, they do not fully explore the complementarity of features. In this paper, the authors propose a novel multi‐feature and multi‐level fusion network (MMF‐Net), which extracts and combines joint features, bone features and trajectory features at multiple levels to estimate 3D human pose. In MMF‐Net, firstly, the bone length estimation module and the trajectory multi‐level fusion module are used to extract the geometric size information of the human body and multi‐level trajectory information of human motion, respectively. Then, the fusion attention‐based combination (FABC) module is used to extract multi‐level topological structure information of the human body, and effectively fuse topological structure information, geometric size information and trajectory information. Extensive experiments show that MMF‐Net achieves competitive results on Human3.6M, HumanEva‐I and MPI‐INF‐3DHP datasets.
New low‐noise sensorless control strategy for permanent magnet synchronous motor drives based on variable‐frequency voltage signal injection
Authors: Zhu Haotian , Zhang Li , Peng Zhongfei , Tan Feixue , Xu Lei 
Published: January 2025

AbstractThis paper proposes a new low‐noise sensorless control strategy for the permanent magnet synchronous motor (PMSM) drives to tackle audible noise caused by high‐frequency injection method. The traditional noise reduction methods face limitation in improving estimated accuracy of rotor position due to the signal delay with fixed frequency signal. To overcome this issue, a low‐noise sensorless control strategy is developed, which consists of two parts. First, with the injection of the proposed variable‐frequency voltage signal, significant noise reduction can be achieved due to its characteristics of multi‐frequency switching and multi‐modal amplitude tuning. Secondly, a delayed effects‐aware demodulated signal is designed to reduce the impact of system delay, which can further improve the estimation accuracy of rotor position. As a result, the proposed low‐noise sensorless control scheme can suppress audible noise and further improve position estimation accuracy. Also, the steady‐state and dynamic performances of the motor drive system can be enhanced. Finally, comparative experiments under steady‐state and dynamic conditions demonstrate the superiority of the proposed method in PMSM.

Abstract
Background and study aims Endoscopic mucosal resection (EMR) is a safe and minimally invasive procedure to remove colorectal non-pedunculated polyps. Recurrence rates are relatively high and differ among endoscopists. We aimed to evaluate whether endoscopists are able to predict recurrence based on thorough inspection of images of mucosal defects after an assumed complete EMR.
Methods We developed an online survey in which endoscopists were invited to indicate whether they expected recurrence to develop when inspecting 30 post-EMR defect images. All EMRs were considered to be complete resections by the performing endoscopist. Participating endoscopists were scored based on the number of correct answers regarding presence or absence of recurrence found at first surveillance colonoscopy.
Results A total of 140 endoscopists responded to the survey (response rate 25%). A total of 124 respondents with a mean age of 46.5 years evaluated the 30 images. The overall score in the cohort was 70%, indicating that respondents were able to correctly predict recurrence in three-quarters of cases with an overall level of certainty of 53.4%. When comparing results of experienced and less experienced endoscopists based on the number of endoscopic submucosal dissections and/or EMRs performed yearly, no difference (71% versus 69%, P = 0.23) was found.
Conclusions This study shows that recurrences after presumed complete EMR can reasonably well be predicted by both experienced and less experienced endoscopists when evaluating images with mucosal defects. Thorough inspection of the post-EMR defect may reduce recurrence rates by recognizing and subsequent treatment of suspect areas.

AbstractAs governments around the world seek to develop and implement co-management practices with Indigenous peoples and local communities, there are many questions about how to foster collaborative and just agreements that support self-determination. Despite policy advancements enabling more co-management and shared stewardship within the United States (U.S.), possibilities for co-management are complicated by historical injustices that have hindered Tribal access to ancestral land and cultural practices. We use a multiple case study approach, examining three case studies from the Western U.S. that illustrate challenges facing Tribes and interventions used to improve land management relationships. The first case study focuses on the relationship between the Oglala Sioux Tribe and the U.S. government and highlights that historical injustices continue to affect Tribal land management. The second case study explores the collaborative management of Bears Ears National Monument, showcasing a decolonized approach endorsed by Tribes seeking to reclaim their inherent rights to the land. The third case study examines the Snoqualmie Tribe as an example of a sovereign Tribe embodying the concept of “Land Back.” Tribes have utilized strategies, such as co-management, coalition building, and land reacquisition, to maintain control over lands important to their populations. These strategies promote power-sharing, resource distribution, trust-building, and the integration of Indigenous knowledge with Western science. Nonetheless, failure to recognize and account for the weight of broken treaties, discriminatory laws and policies, and the historical trauma caused by these injustices emphasizes the importance of understanding the dynamics surrounding Tribal land management. As government-led land management paradigms around the world shift to consider self-determination of Indigenous nations and communities as a critical piece of improved stewardship, decision makers have many historically-informed dynamics to consider when shaping future co-management practices. KEYWORDS: co-management, Indigenous, “Land Back”, stewardship, Tribes, and sovereignty.

Abstract
The manipulation of magnetization and spin polarization using electrical currents represents a fundamental breakthrough in spintronics. It has formed the foundation for data storage and next-generation computing systems. Spin-transfer torque (STT) and spin-orbit torque (SOT) have emerged as prominent mechanisms in current-driven magnetization switching. However, these approaches typically require critical current densities in the range of 106 to 109 A⋅cm−2, resulting in significant heat generation during data writing processes. Herein, we report the discovery of an ultralow-vertical-current magnetization switching effect in a van der Waals ferromagnetic/ferroelectric heterostructure based on the modulation of the critical magnetic field (H
C) using small vertical currents, with a critical current density as low as 1.81 A⋅cm−2 and an average effective field (H
eff/J
C) as high as 150.3 mT⋅A−1⋅cm2. This unique magnetization switching effect with ultralow-critical-vertical-current densities typically six to nine orders of magnitude lower than those of the STT and SOT provides a new transformative and viable pathway for developing next-generation spintronic and quantum technologies.

Published: January 2025

Abstract
The valley degrees of freedom, representing quantum states of energy extremes in momentum space, are introduced into the acoustic system, and the valley topological insulator analogs of the quantum valley Hall effect can control the sound wave to observe topological valley transport against backscattering in domain walls of different valley topological phase structures. However, most of the earlier acoustic topological insulators are based on Bragg scattering and topological states only work in a single frequency band, which limits the design of applications for multiband communications. Here, we propose multiband acoustic valley Hall topological metamaterials based on weak interaction of local resonance subunits with isolated modulation. Valley topological phase transitions exists at two separated frequency bands by combining acoustic meta-atoms and meta-molecules and simply rotating the scatterers. Both the simulated and experimental results demonstrate structure-dependent dual-band topological edge states. Such a design may provide new ideas for multi-channel acoustic communications and subwavelength acoustic energy harvesting.

Abstract
To reduce fluctuations in the performance of lattice-mismatched solar cells within a wafer, it is necessary to characterize and quantify the effect of misfit dislocations, caused by strain relaxation, on the performance of a solar cell. To this end, the relationship between the preferential glide planes (GPs) and the carrier generation-recombination process in InGaAs solar cells with low (LowV) and high (HighV) open-circuit voltages has been investigated in this study. The GPs of the β dislocations in the HighV cells were uniformly controlled in the wafer plane. However, the LowV cells contained a mixture of two in-plane regions, in which the GPs of the β dislocations were controlled by the surface atomic steps during their growth on a vicinal substrate (LowV-sub region) or by the InGaP ordering effect (LowV-ord region). The results of the microwave photoconductivity decay method and our newly-developed laser heterodyne photothermal displacement method suggested that the photoexcited carrier concentration was low in the LowV-ord region. A photoluminescence measurement as a function of temperature further revealed that indium fluctuations occurred due to the presence of the GPs of the β dislocation. The LowV cells exhibited high indium composition and reduced bandgap. Thus, a small photoexcited carrier concentration and reduced bandgap energy decreased the difference between the quasi-Fermi levels of electrons and holes, resulting in a small V
OC. The photovoltaic performance could be determined by the density of the threading dislocations and the corresponding fluctuations in the indium composition owing to the different GPs of the β dislocations.

Abstract
Understanding the electronic properties of dislocations is key to tailoring their properties in silicon carbide (SiC)-based electronic devices. By combining the Kelvin probe force microscopy analysis and first-principles calculations, we investigate the effect of aluminum (Al) dopants and surface oxides on the electronic properties of dislocations in p-type SiC. It is found that dislocations, including threading screw dislocations (TSDs), threading edge dislocations (TEDs), and basal plane dislocations (BPDs) create deep acceptor-like states in p-type SiC. The defect levels move upwards in the order of BPD, TED and TSD, which closely relates with the lattice distortion of dislocations. Interestingly, we find that the defect levels of dislocations are higher than that of Al dopants in p-type SiC. First-principles calculations indicate that the defect formation energies of Al dopants at the cores of dislocations are higher than those in the perfect region of p-type SiC, as a result of the steric effect. This indicates that the concentration of Al acceptors at the dislocation cores is lower than that in the perfect region, resulting in the higher defect level positions of dislocations in p-type SiC. Additionally, we find that surface oxidation reduces the difference of defect-level positions between dislocations and the perfect region of p-type SiC, which paves the way for tailoring the electronic properties of dislocations in p-type SiC.

Abstract
Precipitable water vapor (PWV) is crucial for weather forecasting and climate change research. However, accurate PWV estimation is challenging, especially in the absence of measured meteorological data. In this study, we develop a conversion model based on the random forest algorithm, called RPWV, which can directly derive PWV from zenith total delay without measured meteorological data. The results indicate that the RPWV model demonstrates high accuracy and reliability for PWV retrieval across North America. Specifically, using global navigation satellite system PWV as a reference, the bias and root mean square (RMS) values for RPWV are 0.01 mm and 1.87 mm, respectively. Moreover, compared with the conventional linear model and backpropagation neural network model, the accuracy of the RPWV is improved by 81.3% and 13.4%, respectively. In contrast to radiosonde PWV, the bias and RMS values of the RPWV are 1.85 mm and 3.40 mm, respectively. This model provides a straightforward and efficient method for estimating PWV and has potential for weather forecasting and climate research in environments where meteorological data is scarce.
