Earlier sources: Hardware
Hardware is the physical foundation of computing: chips, sensors, devices, networks, and the processes that manufacture them. Follow semiconductor research, compute architectures, and engineering developments alongside their software and energy connections.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗521 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Integrated design and reliability enhancement technology of quantum current sensor for non-invasive measurement in power grid ↗
Non-invasive, high-precision current measurement is essential for smart grid perception, yet conventional clamp-on current transformers suffer from reduced accuracy under low-load conditions, battery dependence, and maintenance constraints. To address these challenges, this study proposes an NV-compatible solid-state quantum current sensing framework based on spin-resonance magnetic-field transduction, designed for integrated deployment and stable operation in practical grid environments. A non-invasive clamp structure converts line current into measurable magnetic signals, while a self-powere…

Advances in Cold Spray for Repair and Additive Manufacturing: A Review ↗
Cold spray (CS) technology has established itself as a versatile solid-state deposition process with significant potential for both repair applications and the manufacturing of bulk parts. This review examines recent advances in CS, emphasizing its unique ability to deposit metals and composites without melting, thereby minimizing oxidation, thermal distortion, and residual stresses. These advantages have positioned CS as a technique with all the credentials for being used within industry for restoring damaged components, especially, where high microstructural quality and mechanical integrity…

Scalable data fabric for smart manufacturing: A connector-based approach to industrial data integration ↗
The growing adoption of Industrial Internet of Things (IIoT) technologies enables new opportunities for data-driven manufacturing. However, large-scale deployment remains hindered by heterogeneous device protocols, inconsistent semantics, and the continued use of legacy systems. Existing approaches often lack a unified method for achieving technical, syntactic, and semantic interoperability across diverse industrial devices. We propose a Data Fabric architecture tailored for IIoT environments. It defines four core functionalities essential for interoperable data integration: uniform messaging,…

Operating Envelopes of Synchronous and Asynchronous Federated Learning Under Communication Impairments in Smart-Grid Sensor Networks ↗
Federated learning (FL) for distributed smart-grid monitoring is shaped jointly by statistical heterogeneity and communication timing. This study evaluates protocol operating envelopes rather than proposing a new aggregator. A frozen confirmatory campaign compares deadline-constrained FedAvg, FedAsync, FedBuff, and FedStaleWeight under ideal, intermittent, and degraded communication using equal client-dispatch and equal simulated-time budgets. In response to peer review, we add a separate physics-backed validation campaign using pandapower AC power flow, five independent physical trajectories,…

Electrochemical sensor based on Ag-metal organic framework/carbon black nanocomposite for the selective detection of Ticagrelor ↗
Ticagrelor (TIC) is an effective drug in inhibiting platelets and is useful for preventing cardiovascular death, ischaemic stroke, or myocardial infarction. In this regard, a novel electrochemical sensor was reported based on a glassy carbon electrode modified with a carbon black/Ag-metal organic framework nanocomposite (GCE/CB/Ag-MOF) for selective TIC detection. To the best of our knowledge, the electrochemical application of a CB/Ag-MOF composite for TIC determination has not previously been reported. The proposed electrode was prepared by creating a conductive platform using Ag-MOF-decorat…

Human–AI-Assisted digital twins for advanced manufacturing: toward industry 5.0 ↗
Abstract Digital twins are increasingly recognized as key enablers of human-centric Industry 5.0 manufacturing. Yet existing reviews rarely examine digital twin architectures, AI methods, human-in-the-loop collaboration, and interaction technologies within a unified analytical framework. This paper systematically synthesizes eighty-two peer-reviewed studies, identified through a PRISMA-2020 systematic search of Scopus, the Web of Science Core Collection, and IEEE Xplore, into a comprehensive analysis of human–AI-assisted digital twins in advanced manufacturing. Four research questions structur…

5D Printing in Additive Manufacturing: Current Status, Applications, and Future Perspectives ↗
Since the late 1980s, additive manufacturing (AM) has emerged as a prominent fabrication technology, experiencing significant advancements over the past decades. Even with its rapid development, this technology still faces many manufacturing challenges. Driven by the development of AM, 5D printing evolved from conventional 3D printing by incorporating five controlled degrees of freedom (three translational and two rotational axes) to enable non-planar deposition, curved-layer fabrication, and improved control of deposition orientation. This review critically analyses and summarizes 5D printing…

InAsSb surface quantum well with in situ deposited Nb as a platform for hybrid devices ↗
Abstract Semiconductor-superconductor hybrid materials form the basis of quantum devices ranging from gate-tunable qubit platforms to topological quantum applications. These applications require material combinations that offer strong spin-orbit coupling and a large superconducting gap. Here, we present a semiconductor-superconductor hybrid material based on a molecular beam epitaxially grown Indium Arsenide Antimonide surface quantum well with an in-situ deposited Niobium layer. The Indium Arsenide Antimonide surface quantum well offers a low effective mass and strong spin-orbit interaction,…

IC-GAP: Inscribed-Circle-Based Geometric Adaptive Processor for Elongated Object Detection in Remote Sensing ↗
Oriented object detection in remote sensing images has achieved substantial progress, yet non-maximum suppression (NMS) remains vulnerable to angular variation when the overlap of high-aspect-ratio objects is measured with rotated bounding boxes. To address this problem, the inscribed-circle-based geometric adaptive processor (IC-GAP), a training-time geometric regularization framework for elongated object detection, is proposed. First, inscribed-circle intersection over union (IC-IoU) is introduced, which uses a rotation-invariant geometric core to provide a stable pairwise optimization signa…

Cross-Modal Sensor Data Segmentation Using Foot Pressure and Inertial Signals ↗
When extracting features for activity recognition, applying a fixed-length sliding window without considering activity transition timing may result in multiple activities being included within a single window, potentially degrading recognition performance. To address this issue, we propose an activity segmentation framework centered on a foot-pressure-based segmentation method (FP). The framework further incorporates multiple segmentation strategies by combining the proposed foot-pressure-based method with a conventional spectral transition measure-based method (STM), and investigates their ef…

How to assess evidence about Hardware
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
