In recent years, the edge computing paradigm enables the movement of processing units and storage nearer to the data available locations. The mechanism completes the computation in a short span of time in minimum bandwidth. Edge ecosystem is a type of distributed computing that is sensitive to topology and geography;the Internet of Things is a prime instance of this. Rather than referring to a single technology, Edge computing refers to an architecture. This paper proposes a resource allocation methodology that will enliven the situation between users and edge servers. By creating continuous control at the edge servers to determine resource allocation, edge computing improves reaction time, provides high security with decreased risk, scalability, lowers transmission costs, and versatility (offload targets, migration bandwidth and computing resources). The Deterministic Policy Gradient, Deep learning and Quality Network concepts are combined in the proposed system. The continuous action space is achieved by a deterministic policy gradient. The experience relay includes a quality network. In the proposed system, the actor-critic network produces a single continuous action instead of resulting probability based actions. The critic-part uses Q-value from a quality network based on current status and activity. The goal of the proposed system is to develop a Deep Deterministic Policy Gradient methodology to allocate servers for mobile users with the help of the Edge computing while taking computation resources, offloading goals and migration bandwidth into consideration. The simulation result indicates that deterministic policy gradients integrated deep learning models improve the system performance compared with Game theory. © 2024 IEEE.

The advances in machine learning (ML) tools and techniques have enabled the non-intrusive collection and rapid analysis of massive amounts of data involving athletes in competitive collegiate sports. It has facilitated the development of services that a coach can employ in analyzing these data into actionable insights in designing training schedules and effective strategies for maximizing an athlete’s performance, while minimizing injury risk. Collegiate sports utilize data to get a competitive advantage. While game statistics are publicly available, relying on more than one form of data can help reveal a pattern. We developed a framework that considers various modalities and creates an athletic signature to predict their future performance. Our research involves the study of 42 distinct features that quantify various internal/external stressors the athletes face to characterize and estimate their athletic readiness (in the form of reactive strength index modified—RSImod) using ML algorithms. Our study, conducted over 26 weeks with 17 collegiate women’s basketball athletes, developed a framework that first performed sensitivity analysis using a hybrid approach combining the strengths of various filter-based, wrapper-based, and embedded feature importance techniques to identify the features most significantly impacting athlete readiness. These features were then categorized into four moderating variables (MVs, i.e. factors): sleep, cardiac rhythm, training strain, and travel schedule. Further, we used factor analysis to enhance interpretability and reduce computational complexity. A hybrid boosted-decision-trees-based model designed based on athlete clusters predicted future athletic readiness based on MVs with a mean squared error (MSE) of 0.0102. Partial dependence plots (PDPs) helped qualitatively learn the relationship between the moderating variables and the RSImod score. Athletic signatures, uniquely defining athlete-specific MV patterns, account for intra-indi

Hydrogen is a highly promising energy carrier because of its renewable and clean qualities. Among the different methods for H2production, photoelectrocatalysis（PEC） water splitting has garnered significant interest, thanks to the abundant and perennial solar energy. Single-atom catalysts（SACs）, which feature well-distributed atoms anchored on supports, have gained great attention in PEC water splitting for their unique advantages in overcoming the limitations of conventional PEC ***, we comprehensively review SAC-incorporated photoelectrocatalysts for efficient PEC water splitting. We begin by highlighting the benefits of SACs in improving charge transfer, catalytic selectivity, and catalytic activity, which address the limitations of conventional PEC reactions. Next, we provide a comprehensive overview of established synthetic techniques for optimizing the properties of SACs, along with modern characterization methods to confirm their unique structures. Finally, we discuss the challenges and future directions in basic research and advancements, providing insights and guidance for this developing field.

Learned, uncertainty-driven adaptive acquisition for photon-efficient scanning microscopy

Optics Express 2025年第6期33卷 12269-12287页

Scanning microscopy systems, such as confocal and multiphoton microscopy, are powerful imaging tools for probing deep into biological tissue. However, scanning systems have an inherent trade-off between acquisition time, field of view, phototoxicity, and image quality. This often results in noisy measurements when fast, large field of view, and/or gentle imaging is needed. Deep learning could be used to denoise noisy microscopy measurements, but these algorithms can be prone to hallucination, which can be disastrous for medical and scientific applications. We propose a method to simultaneously denoise and predict pixel-wise uncertainty for scanning microscopy systems, improving algorithm trustworthiness and providing statistical guarantees for deep learning predictions. Furthermore, we propose to leverage this learned, pixel-wise uncertainty to drive an adaptive acquisition technique that rescans only the most uncertain regions of a sample, saving time and reducing the total light dose to the sample. We demonstrate our method on experimental confocal and multiphoton microscopy systems, showing that our uncertainty maps can pinpoint hallucinations in the deep learned predictions. Finally, with our adaptive acquisition technique, we demonstrate up to 16× reduction in acquisition time and total light dose while successfully recovering fine features in the sample and reducing hallucinations. We are the first to demonstrate distribution-free uncertainty quantification for a denoising task with real experimental data and the first to propose adaptive acquisition based on reconstruction uncertainty. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.
