AbstractThe deformation and failure of coal walls in front of a working face cause significant difficulties during mining operations. This study reveals the nonuniform distribution of bearing pressure in front of coal walls based on in situ monitoring data and numerical simulation. Therefore, an eccentric compression mechanical model was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio of the compression bar is introduced to define coal walls. The results showed that instability failure occurs when λ > λc and material failure occurs when λ ≤ λc. The instability failure‐type coal wall spalling was related to the mining height, eccentricity of roof pressure, the horizontal force, and the reaction moment of the floor. The material failure‐type coal wall spalling was related to the cohesion, the internal friction angle of the coal, the upper pressure, and the horizontal force of coal walls. Unstable and destructive coal wall peeling usually occurs at a height of 0.5–0.6 times the mining height, while material damage to coal wall peeling is determined to occur within the range of 0.4–0.6 times the mining depth. The findings contribute to the understanding of the deformation and failure of coal walls.

AbstractAimsUncertainty exists about defining true iron deficiency (ID) in heart failure (HF) patients. We assessed the relationship of different ID definitions with cardiac structure and function, congestion, exercise capacity, and prognosis in HF outpatients.Methods and resultsIron deficiency was defined according to guidelines (G‐ID: ferritin <100 ng/ml or ferritin 100–299 ng/ml with transferrin saturation [TSAT] <20%). Alternative ID definitions based on TSAT (<20%), iron (≤13 μmol/L), and ferritin (<100 or < 300 ng/ml) were explored. Relationships with rest/exercise measures of cardiac function and congestion using ultrasound, effort intolerance and adverse outcome (HF hospitalizations or all‐cause mortality) were assessed. Of 1502 patients (72% with left ventricular ejection fraction [LVEF] ≥50%), 471 (31%) had TSAT <20%, while 728 (48%) had G‐ID. Patients with TSAT <20% or G‐ID had greater left atrial volume but similar LVEF. Lower TSAT, iron and haemoglobin, but not ferritin, were associated with more signs of congestion by ultrasound. After correcting for multiple clinical variables, including haemoglobin, TSAT was directly associated with peak oxygen uptake (standardized coefficient 0.069, p = 0.041), while ferritin was not. There was no interaction with HF phenotype (HF with preserved vs. reduced LVEF). During a median follow‐up of 18 months, TSAT <20% and iron ≤13 μmol/L were associated with worse outcomes in models adjusted for clinical variables, including LVEF and N‐terminal pro‐B‐type natriuretic peptide (hazard ratio 2.48, 95% confidence interval 1.88–3.17 and 1.93, 1.48–2.52, respectively), while G‐ID or ferritin <100 or <300 ng/ml were not.ConclusionIn HF outpatients, TSAT <20% is more consistently associated with congestion by ultrasound and poorer functional capacity than other ID definitions, irrespective of LVEF. TSAT <20% and iron ≤13 μmol/L, but not G‐ID or ferritin‐based ID, predict a worse prognosis in HF outpatients with preserved and reduced LVEF.
Visualizing Uncertainty in Time Series Forecasts: The Impact of Uncertainty Visualization on Users' Confidence, Algorithmic Advice Utilization, and Forecasting Performance
Authors: Leffrang Dirk , Müller Oliver 
Published: November 2024

ABSTRACTTime series forecasts are always associated with uncertainty. However, experimental studies on the impact of uncertainty communication provide inconclusive results on the effect of providing this uncertainty to end users. In this study, we examine the impact of uncertainty visualizations on advice utilization in the context of time series forecasts with line charts. Based on a literature review, we identified probabilistic framing versus frequency framing as a theoretical foundation for studying the topic. We then used the Judge Advisor System (JAS) as a framework to create an experimental design with two treatments (95% prediction interval [PI] and ensemble plots), one control group (point plot), and various mediating variables (e.g., confidence, graph literacy, and domain knowledge). The results of an online experiment () indicate a U‐shaped relation between uncertainty visualization and forecasting performance. Additionally, we examine how confidence, advice utilization, and other factors mediate the effect of uncertainty visualizations. This paper highlights the benefits of PI plots for researchers and practitioners engaged in the development of effective uncertainty visualizations for decision‐making processes.

Published: November 2024

ABSTRACTThis article presents a contemporary review of human resource management (HRM) research on algorithmic technologies, including artificial intelligence, machine learning, and natural language processing. By connecting these recent advancements to the long‐standing scholarly tradition of HRM‐technology relations, this review examines current knowledge on how algorithmic technologies are reshaping three key areas: (1) work structures and design, (2) HR delivery activities, and (3) the management of technology workers. Using a threefold conceptualization of technology—the tool view, proxy view, and ensemble view—this review explores how organizations employ algorithmic systems to enhance productivity, how the human agency interacts with and resists these technologies, and how broader social, cultural, and institutional contexts shape the use of algorithms in HRM. Additionally, this article offers suggestions for future research, highlighting the unique opportunities algorithmic technologies provide to HR scholars for making enduring contributions to the broader conversations on HRM and technology.

AbstractTo assess the cost‐effectiveness of low‐dose aspirin compared to placebo for the prevention of recurrent preterm birth from a healthcare perspective. This was a cost‐effectiveness analysis alongside a multicenter, randomized, double‐blinded, placebo‐controlled trial. We included women with a singleton pregnancy and a previous spontaneous preterm birth <37 weeks of gestation of a singleton. Women were randomized between aspirin 80 mg daily and placebo, initiated between 8 and 16 weeks of gestation. We estimated the difference in preterm births (<37 weeks of gestation), and maternal and neonatal healthcare costs using seemingly unrelated linear regression analyses. Bootstrapping was performed to estimate statistical uncertainty. A total of 387 women were included: 194 in the aspirin group and 193 in the placebo group. We observed a small, statistically non‐significant difference in preterm birth (21.2% vs. 25.4%; risk difference −4.3%; 95% CI: −12.7% to 4.1%) and healthcare costs (mean –€99; 95% CI: –€2385 to €2325) in the aspirin group compared to placebo. The cost‐effectiveness acceptability curve showed that the probability of aspirin being cost‐effective was 54% for a willingness to pay threshold of €0 for one prevented preterm birth and 78% for €50 000 for one prevented preterm birth. Our findings suggest that aspirin is the dominant strategy over placebo for the prevention of preterm birth. However, there was substantial uncertainty around the results and definite conclusions regarding the cost‐effectiveness of aspirin cannot be drawn.

ABSTRACTSevere infantile tracheobronchomalacia (TBM) is often treated with invasive surgery and fixed‐size implants to support the trachea during respiration. A novel 3D‐printed extra‐luminal splint has been developed as a flexible and bioresorbable alternative. Therefore, the goal of the present study was to use an in vitro breathing simulator model to comprehensively evaluate the structural stiffness and failure modes of two sizes of a novel bioresorbable 3D‐printed splint design under a range of physiological degradation conditions. Two thicknesses, 2 mm and 3 mm, of a novel 3D‐printed bioresorbable splint were evaluated under two different degradation conditions, phosphate‐buffered saline (PBS) and sodium hydroxide (NaOH). The splints were subjected to simulated breathing loading, involving a cyclic opening and closing of the splint by 2 mm, for a targeted duration of 7.5 to 30 million cycles. A separate new set of splints were statically soaked in their respective degradation condition for a comparative analysis of the effects of cyclic loading by the degradation medium. After successfully simulated breathing or static soaking, non‐destructive tensile and compressive strengths were evaluated, and overall stiffness was calculated from destructive tensile testing. The present study indicates that the splints were more significantly degraded under simulated breathing conditions than under soaking. Cyclic simulated breathing specimens failed far earlier than the intended duration of loading. Over time, both 2 mm and 3 mm splints became increasingly more flexible when subjected to the static degradation conditions. Interestingly, there was little difference in the compressive and tensile strengths of the 2 mm and 3 mm thickness splints. The bioresorbable nature of PCL offers a valuable advantage as it eliminates the need for splint removal surgery and increases device flexibility over time with degradation. This increased flexibility is crucial because it allows for uninhibited growth and development of the infant's trachea over the intended use period of 2 years. The results of this study confirm that the splints were able to withstand tensile forces to prevent tracheal collapse. This study further supports the successful use of 3D‐printed splints in the treatment of infantile TBM.

ObjectiveEwing sarcoma (ES) is a rare aggressive malignancy that can present in the sinonasal region. The objective of this study is to investigate the demographics, presentation, management, and outcomes of patients with sinonasal ES.Data SourcesPubMed, Web of Science, SCOPUS, CINAHL, and Cochrane Library.Review MethodsA scoping review of cases of sinonasal ES was performed. Inclusion criteria consisted of case reports, series, or retrospective reviews.Results785 total articles were retrieved. 72 articles met inclusion criteria and were included in the final review for a total of 93 cases. 48 (53%) patients were male. Mean age at diagnosis was 26.4 years old (range 1–89). Nasal obstruction (N = 55, 59%), epistaxis (N = 35, 38%), and impaired vision (N = 29, 29%) were the most common symptoms. On examination, 38 (41%) patients had a nasal cavity mass. Most tumors (N = 33, 35%) were located in the maxillary sinus. 44 (47%) were left sided and 4 (4%) were bilateral. The most utilized treatment modalities were surgical resection with adjuvant chemoradiotherapy (N = 27, 29%), chemoradiotherapy alone (N = 24, 26%), and surgical resection with adjuvant chemotherapy (N = 14, 15%). 56 patients had no evidence of disease (60%), 14 patients died with disease (15%), and 9 patients were alive with disease (10%) at the time of follow‐up.ConclusionsTo our knowledge, we report the first scoping review of sinonasal ES. Patients generally present with non‐specific sinonasal symptoms. Surgery with adjuvant chemoradiation is the most common treatment modality for these patients.Level of EvidenceNA Laryngoscope, 2024
A Reconfigurable Metasurface Antenna for Arbitrarily Polarized Beam Generation and Advanced Polarization Detection

Published: November 2024

AbstractA reconfigurable metasurface antenna (RMA) is proposed that can be used as a full polarized beam launcher to generate arbitrarily polarized radiation waves, or as a polarization detector to identify the polarization state of unknown incoming wave. It is shown that integrating Positive‐Intrinsic‐Negative (PIN) diodes and varactor diodes on the metasurface can independently control the amplitudes and phases of two orthogonal polarization components of the radiated electromagnetic (EM) waves through bias voltage, further achieving real‐time control of the polarization states. The proposed RMA can also be used as a polarization detector to identify all possible polarization states of unknown incoming waves quickly. A prototype of RMA is designed and fabricated, and the functions of arbitrary polarization generation and detection are validated by experiments, which are consistent very well with the theoretical predictions. Due to the advantages of low profile, versatility, and fast response, the proposed RMA is promising to be used in the future wireless communication, radar, and so on.

Published: November 2024

AbstractTunable orthogonal full‐color luminescence has emerged as a new class of smart luminescence phenomenon with wide applications ranging from photonics to biomedicine. However, the current research is focused on complex multilayer core‐shell nanostructures (e.g., 5–8 shell layers) with a single upconversion mode, greatly limiting their synthesis and practical application. Herein, this work proposes a simple core‐shell structure to integrate upconversion and downshifting dual‐mode luminescence based on Gd3+‐mediated interfacial energy transfer and Ce3+‐assisted cross relaxation. This design is able to suppress cross‐talk of multiple emissions and simplify the sample structure by removing the conventionally required intermediate isolation layer. Importantly, it further enables the arbitrarily controllable multicolor output at a single nanoparticle level by adopting the tri‐channel selective excitation wavelengths (980/808/254 nm), greatly expanding the conventional red‐green‐blue (RGB) color gamut. Moreover, the use of these nanoparticles promotes the information security level and the complexity of anti‐counterfeiting modes by adopting a pre‐set logic Morse information encryption and decryption strategy. These results provide effective guidance for the rational nanostructure design of novel orthogonal trichromatic emissive materials for a variety of frontier applications such as advanced anticounterfeiting and information security.

AbstractPurposeTo develop a robust single breath‐hold approach for volumetric lung imaging at 0.55T.MethodA balanced‐SSFP (bSSFP) pulse sequence with 3D stack‐of‐spiral (SoS) out‐in trajectory for volumetric lung imaging at 0.55T was implemented. With 2.7× undersampling, the pulse sequence enables imaging during a 17‐s breath‐hold. Image reconstruction is performed using 3D SPIRiT and 3D l1‐Wavelet regularizations. In two healthy volunteers, single breath‐hold SoS out‐in bSSFP was compared against stack‐of‐spiral UTE (spiral UTE) and half‐radial dual‐echo bSSFP (bSTAR), based on signal intensity (SI), blood‐lung parenchyma contrast, and image quality. In six patients with pathologies including lung nodules, fibrosis, emphysema, and air trapping, single breath‐hold SoS out‐in and bSTAR were compared against low‐dose computed tomography (LDCT).ResultsSoS out‐in bSSFP achieved 2‐mm isotropic resolution lung imaging with a single breath‐hold duration of 17 s. SoS out‐in (2‐mm isotropic) provided higher lung parenchyma and blood SI and blood‐lung parenchyma contrast compared to spiral UTE (2.4 × 2.4 × 2.5 mm3) and bSTAR (1.6‐mm isotropic). When comparing SI normalized by voxel size, SoS out‐in has lower lung parenchyma signal, higher blood signal, and a higher blood‐lung parenchyma contrast compared to bSTAR. In patients, SoS out‐in bSSFP was able to identify lung fibrosis and lung nodules of size 4 and 8 mm, and breath‐hold bSTAR was able to identify lung fibrosis and 8 mm nodules.ConclusionSingle breath‐hold volumetric lung imaging at 0.55T with 2‐mm isotropic spatial resolution is feasible using SoS out‐in bSSFP. This approach could be useful for rapid lung disease screening, and in cases where free‐breathing respiratory navigated approaches fail.

AbstractThe pyridoxal 5′‐phosphate binding protein (PLP‐BP) is believed to play a crucial role in PLP homeostasis, which may explain why it is found in living organisms from all kingdoms. Escherichia coli YggS is the most studied homolog, but human PLP‐BP has also attracted much attention because variants of this protein are responsible for a severe form of B6‐responsive neonatal epilepsy. Yet, how PLP‐BP is involved in PLP homeostasis, and thus what its actual function is in cellular metabolism, is entirely unknown. The present study shows that YggS binds RNA and that the strength of this interaction is modulated by PLP. A key role in RNA binding is clearly played by Lys137, an invariant residue located on a protein loop away from the PLP binding site, whose importance has been highlighted previously. The interaction with RNA is evidently conserved, since it is also observed with human PLP‐BP. The RNA binding site, which is apparently located at the entrance of the PLP‐binding site, is also evolutionarily conserved. It is therefore reasonable to assume that PLP, by defining the conformation of the protein, determines the RNA binding affinity. RNA‐seq analysis of RNA co‐purified with or captured by YggS revealed SsrA and RnpB RNAs, respectively involved in trans‐translation and tRNA maturation, as the major molecular components. This work opens up new horizons for the function of the PLP‐BP, which could be related to its interaction with RNA and modulated by PLP, and thus play a role in an as yet unknown regulatory mechanism.
AMHF‐TP: Multifunctional therapeutic peptides prediction based on multi‐granularity hierarchical features
Authors: Tuo Shouheng , Zhu YanLing , Lin Jiangkun , Jiang Jiewei 
Published: November 2024

AbstractMultifunctional therapeutic peptides (MFTP) hold immense potential in diverse therapeutic contexts, yet their prediction and identification remain challenging due to the limitations of traditional methodologies, such as extensive training durations, limited sample sizes, and inadequate generalization capabilities. To address these issues, we present AMHF‐TP, an advanced method for MFTP recognition that utilizes attention mechanisms and multi‐granularity hierarchical features to enhance performance. The AMHF‐TP is composed of four key components: a migration learning module that leverages pretrained models to extract atomic compositional features of MFTP sequences; a convolutional neural network and self‐attention module that refine feature extraction from amino acid sequences and their secondary structures; a hypergraph module that constructs a hypergraph for complex similarity representation between MFTP sequences; and a hierarchical feature extraction module that integrates multimodal peptide sequence features. Compared with leading methods, the proposed AMHF‐TP demonstrates superior precision, accuracy, and coverage, underscoring its effectiveness and robustness in MFTP recognition. The comparative analysis of separate hierarchical models and the combined model, as well as with five contemporary models, reveals AMHF‐TP’s exceptional performance and stability in recognition tasks.
Epistemic Justice as a “New Normal?” Interrogating the Contributions of Communities of Practice to Decolonization of Knowledge
Authors: Cummings Sarah , Munthali Nyamwaya , Sittoni Toni 
Published: November 2024

ABSTRACTRecently, scholarly communities of practice have emerged with the objective of decolonizing knowledge practices within sustainable development. Their contributions to sustainability and systems change remain underexplored, possibly due to the absence of appropriate conceptual tools to analyze them. This study applies a new conceptual framework of epistemic justice, derived from the philosophical notion of epistemic injustice, to examine how these communities foster more equitable knowledge systems with regards to the social dimensions of sustainable development. Using critical discourse analysis, data from the websites of two scholarly communities of practice were analyzed, revealing their innovative approaches to advancing epistemic justice through knowledge practices. The findings emphasize the utility of the epistemic justice framework in understanding the role of these scholarly communities of practice in fostering social sustainability, specifically by contributing to more equitable knowledge practices and a “new normal.”
