Because of the theoretical challenges posed by the Efficient Market Hypothesis with respect to technical analysis, the effectiveness of technical indicators in high-frequency trading remains inadequately explored, particularly at the minute-level frequency, where the effects of the microstructure of the market dominate. This study evaluates the integration of traditional technical indicators with Random Forest regression models using minute-level SPY data, analyzing 13 distinct model configurations. Our empirical results reveal a stark contrast between in-sample and out-of-sample performance, with R2 values deteriorating from 0.749–0.812 during training to negative values in testing. A feature importance analysis demonstrates that primary price-based features dominate the predictions made by the model, accounting for over 60% of the importance, while established technical indicators, such as RSI and Bollinger Bands, account for only 14–15%. Although the indicator-enhanced models achieved superior risk-adjusted metrics, with Rachev ratios between 0.919 and 0.961, they consistently underperformed a simple buy-and-hold strategy, generating returns ranging from −2.4% to −3.9%. These findings challenge conventional assumptions about the usefulness of technical indicators in algorithmic trading, suggesting that in high-frequency contexts, they may be more relevant to risk management rather than to predicting returns. For practitioners and researchers, our findings indicate that successful high-frequency trading strategies should focus on adaptive feature selection and regime-specific modeling rather than relying on traditional technical indicators, as well as indicating the critical importance of robust out-of-sample testing in the development of a model.

Driving Under the Influence (DUI) has emerged as a significant threat to public safety in recent years. Despite substantial efforts to effectively detect DUI, the inherent risks associated with acquiring DUI-related data pose challenges in meeting the data requirements for training. To address this issue, we propose DUIncoder, which is an unsupervised framework designed to learn exclusively from normal driving data across diverse scenarios to detect DUI behaviors and provide explanatory insights. DUIncoder aims to address the challenge of collecting DUI data by leveraging diverse normal driving data, which can be readily and continuously obtained from daily driving. Experiments on simulator data show that DUIncoder achieves detection performance superior to that of supervised learning methods which require additional DUI data. Moreover, its generalization capabilities and adaptability to incremental data demonstrate its potential for enhanced real-world applicability. Full article

The pursuit of robust 3D object detection has emerged as a critical focus within the realm of computer vision. This paper presents a curriculum-guided adversarial learning (CGAL) framework, which significantly enhances the adversarial robustness and detection accuracy of the LiDAR-based 3D object detector PointPillars. By employing adversarial learning with prior curriculum expertise, this framework effectively resists adversarial perturbations generated by a novel attack method, P-FGSM, on 3D point clouds. By masterfully constructing a nonlinear enhancement block (NEB) based on the radial basis function network for PointPillars to adapt to the CGAL, a novel 3D object detector named Pillar-RBFN was developed; it exhibits intrinsic adversarial robustness without undergoing adversarial training. In order to tackle the class imbalance issue within the KITTI dataset, a data augmentation technique has been designed that singly samples the point cloud with additional ground truth objects frame by frame (SFGTS), resulting in the creation of an adversarial version of the original KITTI dataset named Adv-KITTI. Moreover, to further alleviate this issue, an adaptive variant of focal loss was formulated, effectively directing the model’s attention to challenging objects during the training process. Extensive experiments demonstrate that the proposed CGAL achieves an improvement of 0.82.5 percentage points in mean average precision (mAP) compared to conventional training methods, and the models trained with Adv-KITTI have shown an enhancement of at least 15 percentage points in mAP, compellingly testifying to the effectiveness of our method.

Pharmaceutical 3D printing, combined with nanomaterials and nanodevices, presents a transformative approach to precision medicine for treating neurological diseases. This technology enables the creation of tailored dosage forms with controlled release profiles, enhancing drug delivery across the blood−brain barrier (BBB). The integration of nanoparticles, such as poly lactic-co-glycolic acid (PLGA), chitosan, and metallic nanomaterials, into 3D-printed scaffolds improves treatment efficacy by providing targeted and prolonged drug release. Recent advances have demonstrated the potential of these systems in treating conditions like Parkinson’s disease, epilepsy, and brain tumors. Moreover, 3D printing allows for multi-drug combinations and personalized formulations that adapt to individual patient needs. Novel drug delivery approaches, including stimuli-responsive systems, on-demand dosing, and theragnostics, provide new possibilities for the real-time monitoring and treatment of neurological disorders. Despite these innovations, challenges remain in terms of scalability, regulatory approval, and long-term safety. The future perspectives of this technology suggest its potential to revolutionize neurological treatments by offering patient-specific therapies, improved drug penetration, and enhanced treatment outcomes. This review discusses the current state, applications, and transformative potential of 3D printing and nanotechnology in neurological treatment, highlighting the need for further research to overcome the existing challenges.

The accuracy of hydro-turbine fault diagnosis directly impacts the safety and operational efficiency of hydroelectric power generation systems. This paper addresses the challenge of low diagnostic accuracy in traditional methods under complex environments. This is achieved by proposing a signal preprocessing method that combines complete ensemble empirical mode decomposition with adaptive noise and multiscale permutation entropy (CEEMDAN-MPE) and that is optimized with the crested porcupine optimizer algorithm for the bidirectional long- and short-term memory network (CPO-BILSTM) model for hydro-turbine fault diagnosis. The method performs signal denoising using CEEMDAN, while MPE extracts key features. Furthermore, the hyperparameters of the CPO-optimized BILSTM model are innovatively introduced. The extracted signal features are fed into the CPO-BILSTM model for fault diagnosis. A total of 150 sets of acoustic vibrational signals are collected for validation using the hydro-turbine test bench under different operating conditions. The experimental results demonstrate that the diagnostic accuracy of the method is 96.67%, representing improvements of 23.34%, 16.67%, and 6.67% over traditional models such as LSTM (73.33%), CNN (80%), and BILSTM (90%), respectively. In order to verify the effectiveness of the signal preprocessing method, in this paper, the original signal, the signal processed by CEEMDAN, CEEMDAN-PE, and CEEMDAN-MPE are input into the CPO-BILSTM model for controlled experiments. The results demonstrate that CEEMDAN-MPE effectively denoises hydro-turbine acoustic vibrational signals while preserving key features. The method in this paper integrates signal preprocessing and deep learning models and, with the help of intelligent optimization algorithms, significantly enhances the model’s adaptive ability, improves the model’s applicability under complex operating conditions, and provides a valuable supplement for hydro-turbine fault diagnosis.

Optical remote sensing images, as a significant data source for Earth observation, are often impacted by cloud cover, which severely limits their widespread application in Earth sciences. Synthetic aperture radar (SAR), with its all-weather, all-day observation capabilities, serves as a valuable auxiliary data source for cloud removal (CR) tasks. Despite substantial progress in deep learning (DL)-based CR methods utilizing SAR data in recent years, challenges remain in preserving fine texture details and maintaining image visual authenticity. To address these limitations, this study proposes a novel diffusion-based CR method called the Dual-branch Multimodal Conditional Guided Diffusion Model (DMDiff). Considering the intrinsic differences in data characteristics between SAR and optical images, we design a dual-branch feature extraction architecture to enable adaptive feature extraction based on the characteristics of the data. Then, a cross-attention mechanism is employed to achieve deep fusion of the multimodal feature extracted above, effectively guiding the progressive diffusion process to restore cloud-covered regions in optical images. Furthermore, we propose an image adaptive prediction (IAP) strategy within the diffusion model, specifically tailored to the characteristics of remote sensing data, which achieves a nearly 20 dB improvement in PSNR compared to the traditional noise prediction (NP) strategy. Extensive experiments on the airborne, WHU-OPT-SAR, and LuojiaSET-OSFCR datasets demonstrate that DMDiff outperforms SOTA methods in terms of both signal fidelity and visual perceptual quality. Specifically, on the LuojiaSET-OSFCR dataset, our method achieves a remarkable 17% reduction in the FID metric over the second-best method, while also yielding significant enhancements in quality assessment metrics such as PSNR and SSIM.

Background/Objectives: Post-activation performance enhancement (PAPE) has been explored for its potential to improve general performance in combat sports. This systematic review and meta-analysis investigated the effects of PAPE protocols on physical performance, focusing on differences across disciplines, competitive levels, and testing methods. Methods: A PRISMA-guided search (2010–2023) identified 19 studies examining PAPE protocols in combat sports athletes. The inclusion criteria required human trials using defined PAPE protocols, with outcomes of general performance indicators such as countermovement jumps (CMJs). A meta-analysis was conducted on data from 866 athletes using random effects modeling. Results: The PAPE protocols yielded a pooled effect size of 0.136 (95% CI, 0.008–0.263) across 866 athletes. Taekwondo athletes exhibited the most pronounced improvements in CMJ performance, particularly when using protocols that combined repeated vertical jumps with heavy-resistance cluster sets, and with dynamic, sport-specific movements such as the bandal chagui protocol achieving an effect size of 1.19 (p < 0.001). Conversely, Muay Thai athletes experienced performance declines when the protocols incorporated highly specific techniques, such as roundhouse kicks (ES = −1.36, p = 0.009). Analysis by competitive level revealed pooled effect sizes of 0.14 (95% CI, −0.01 to 0.29) for amateur athletes and 0.13 (95% CI, −0.11 to 0.38) for elite athletes, with no statistically significant differences observed between these groups. Conclusions: PAPE’s effectiveness depends on tailoring protocols to the competitive level and discipline. Short rest intervals support plyometric protocols for amateurs, while heavy-resistance exercises enhance elite performers. Further research is needed to standardize PAPE protocols and explore discipline-specific adaptations. Full article

The parameter configuration of traditional visual SLAM algorithms usually relies on expert experience and extensive experiments, and the parameter configuration needs to be reset as the scene changes, which is a complex and tedious process. To achieve parameter adaptation in visual SLAM, we propose the Mamba-DQN method, which transforms complex parameter adjustment tasks into policy learning assignments for the agent. In this paper, we select the key parameters of visual SLAM to construct the agent action space. The reward function is constructed based on the absolute trajectory error (ATE), and the Mamba history observer is built within the agent to learn the observation trajectory, aiming to improve the quality of the agent’s decisions. Finally, the proposed method was experimented on the EuRoc MAV and TUM-VI datasets. The experimental results show that Mamba-DQN not only enhances the positioning accuracy of visual SLAM and demonstrates good real-time performance but also avoids the tedious parameter adjustment process.

The Arabian sand gazelle (Gazella marica) is a native and highly adaptable species of the Arabian Peninsula. Due to drastic population declines, the species is listed as globally vulnerable. Very little is known about the behavioral ecology of this species in captivity; therefore, this study was designed to investigate the seasonal variations in the activity patterns of Arabian sand gazelles at Al Reem Biosphere Reserve, Qatar. Data were collected in two phases, i.e., summer (September–October 2021) and winter (December 2021–January 2022), for a total of 16 days. Results revealed that feeding and walking (p = 0.001) were the dominant activities in both seasons, yet these were higher in summer compared to winter. Likewise, standing, lying down and other activities (social interactions, defecating, maintenance, sexual behaviors) were also higher in summer compared to winter. All these findings suggest that Arabian sand gazelles are adaptable to harsh environments. However, we strongly recommend a year-round investigation on the impacts of humans, feed types and Arabian Oryx on the behavioral activities of Arabian sand gazelles. In addition, we suggest studying the behavior ecology of the wild scattered populations of Arabian sand gazelles for better management of captive breeding stocks. Full article

The increasing complexity of healthcare delivery and the advancements in medical technology have highlighted the necessity for improved training in nursing education. While traditional training methods have their merits, they often encounter challenges such as limited access to clinical placements, static physical simulations, and performance anxiety during hands-on practice. Virtual reality (VR) has been increasingly adopted for immersive and interactive training environments, allowing nursing students to practice essential skills repeatedly in realistic, risk-free settings. This study presents NursingXR, a VR-based platform designed to help nursing students master essential clinical skills. With a scalable and flexible architecture, NursingXR is tailored to support a variety of nursing lessons and adapt to evolving curricula. The platform has a modular design and offers two interactive modes: Training Mode, which provides step-by-step guided instruction, and Evaluation Mode, which allows for independent performance assessment. This article details the development process of the platform, including key design principles, system architecture, and implementation strategies, while emphasizing its utility and scalability. A mixed-methods evaluation involving 78 participants—both novices and experts—was conducted to evaluate the platform’s usability and user satisfaction. The results underscore NursingXR’s effectiveness in fostering an effective and engaging learning environment as well as its potential as a supplementary resource for nursing training. Full article

This paper presents an advanced Adaptive Sliding Mode Control (ASMC) strategy, specifically developed for a hydrogen production system based on a Proton Exchange Membrane electrolyzer (PEM electrolyzer). This work utilized a static model of the PEM electrolyzer, characterized by its V-I electrical characteristic, which was approximated by a linear equation. The ASMC was designed to estimate the coefficients of this equation, which are essential for designing an efficient controller. The primary objective of the proposed control strategy is to ensure the overall stability of the integrated system comprising both an interleaved buck converter (IBC) and PEM electrolyzer. The control framework aims to maintain the electrolyzer voltage at its reference value despite the unknown coefficients while ensuring equal current distribution among the three parallel legs of the IBC. The effectiveness of the proposed approach was demonstrated through numerical simulations in MATLAB-SIMULINK and was validated by the experimental results. The results showed that the proposed ASMC achieved a voltage tracking error of less than 2% and a current distribution imbalance of only 1.5%. Furthermore, the controller exhibited strong robustness to parameter variations, effectively handling fluctuations in the electrolyzer’s ohmic resistance (Rohm) (from ±28.75% to ±40.35%) and in the reversible voltage (Erev) (from ±28.67% to ±40.19%), highlighting its precision and reliability in real-world applications.

Premiered at the 2024 Adelaide Festival, Is This the Gate? is an opera excerpt composed by Nicholas Lens and set to a libretto written by J. M. Coetzee. It is adapted from the last section of Coetzee’s novel Elizabeth Costello (2003), revolving around the eponymous character’s trial before the gate in the afterworld. This article explores the literary, musical and dramaturgical elements of Is This the Gate? and contends that the adaptation, despite its brevity and incompleteness, indexes and reworks some of the most important intertexts, localities and motifs that connect Coetzee’s early and late works. Allusions to Kafka and Dante frame the scenario for Costello in limbo—a state mirroring a writer’s late-in-life predicament—while references to Australia’s weather and fauna reflect Coetzee’s relationship to his South African roots and adopted home. Further, Costello’s conviction that she is “a secretary of the invisible” holds clues to Coetzee’s deployment of voices and fictional personae since his debut, Dusklands (1974). The last few acts of the opera excerpt evoke themes of desire and mortality that chime with Coetzee’s other Costello narratives, including his latest collection, The Pole and Other Stories (2023). The adaptation ends with Costello’s declaration of her subjectivity, which suggests a writer’s yearning and resolution to go beyond the threshold of life and death. Full article

The Advanced Insect Detection Network (AIDN), which represents a significant advancement in the application of deep learning for ecological monitoring, is specifically designed to enhance the accuracy and efficiency of insect detection from unmanned aerial vehicle (UAV) imagery. Utilizing a novel architecture that incorporates advanced activation and normalization techniques, multi-scale feature fusion, and a custom-tailored loss function, the AIDN addresses the unique challenges posed by the small size, high mobility, and diverse backgrounds of insects in aerial images. In comprehensive testing against established detection models, the AIDN demonstrated superior performance, achieving 92% precision, 88% recall, an F1-score of 90%, and a mean Average Precision (mAP) score of 89%. These results signify a substantial improvement over traditional models such as YOLO v4, SSD, and Faster R-CNN, which typically show performance metrics approximately 10–15% lower across similar tests. The practical implications of AIDNs are profound, offering significant benefits for agricultural management and biodiversity conservation. By automating the detection and classification processes, the AIDN reduces the labor-intensive tasks of manual insect monitoring, enabling more frequent and accurate data collection. This improvement in data collection quality and frequency enhances decision making in pest management and ecological conservation, leading to more effective interventions and management strategies. The AIDN’s design and capabilities set a new standard in the field, promising scalable and effective solutions for the challenges of UAV-based monitoring. Its ongoing development is expected to integrate additional sensory data and real-time adaptive models to further enhance accuracy and applicability, ensuring its role as a transformative tool in ecological monitoring and environmental science.
