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 ↗528 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.

Real-Time Physical-to-Virtual Scene Reconstruction for Dynamic Manufacturing Systems via Semantic—Spatial Mapping ↗
Real-time reconstruction of virtual scenes in response to changing physical conditions remains a challenge in manufacturing digital-twin systems. During manufacturing operations, changes in object positions, orientations, and spatial arrangements require the virtual scene to be updated to reflect the evolving physical environment. Here, we present a physical-scene-driven semantic–spatial mapping framework to support real-time scene reconstruction in dynamic manufacturing systems. The framework integrates visual object detection, point-cloud-based spatial estimation, digital asset retrieval, an…

A Fluorescent Aptamer Sensor Based on Cu-TCPP/rGO for Homogeneous Screening of G-Quadruplex Ligands ↗
Abstract Single-stranded human telomeric DNA can fold into G-quadruplexes, structures composed of stacked G-quartets. Ligands that target G-quadruplex DNA have received considerable attention because of their potential anticancer activity. We developed a Förster resonance energy transfer (FRET) system to identify drugs that stabilize G-quadruplexes with human telomeric DNA in a homogeneous medium using Cu-4,4,4,4-(Porphine-5,10,15,20-tetrayl) tetrakis (benzoic acid)/reduced graphene oxide (Cu-TCPP/rGO) as fluorescence quencher. Fluorescein-tagged human telomeric G-rich DNA (F-GDNA) exhibited…

Recycling of used metal powder for additive manufacturing via vibratory disk milling ↗
Metal additive manufacturing produces less material waste than traditional manufacturing. However, metal powder waste is difficult to recycle compared to the bulk scrap of the same chemistry generated from conventional processes. The powdered material can have a more significant deteriorating impact on the environment. As one of the recycling strategies, ball milling of waste powder has been extensively studied; however, this method can take up to 48 h and typically produces plate-like particles, which are not ideal for many additive manufacturing methods. This study explored vibratory disk mi…

An all-fiber Fabry-Pérot pressure sensor based on an extended silica capillary for sensitivity enhancement ↗
An all-fiber Fabry-Pérot interferometric pressure sensor based on an extended silica capillary is proposed and experimentally demonstrated for high-temperature pressure measurement. The proposed sensor is designed to enhance pressure sensitivity while suppressing pressure-temperature cross-sensitivity. In the proposed structure, pressure-induced axial deformation of the silica capillary is transferred to the Fabry-Pérot interferometric cavity, resulting in an enlarged cavity-length variation and, consequently, enhanced pressure response. Theoretical analysis and experimental results indicate t…

0.9-µm Nd-doped fiber amplifier seeded by a broadband semiconductor optical amplifier ↗
The broadband fiber source features low coherence, high brightness, and high temporal stability, making it attractive for sensing, imaging, and communication. Although broadband fiber sources have achieved remarkable progress in many wavelength bands, high-power 0.9-µm broadband fiber sources, which are critically needed for applications including atmospheric sensing and blue-green light generation for deep-sea communication, remain scarce. In this paper, a 0.9-µm Nd-doped all-fiberized broadband fiber source is demonstrated. The broadband fiber source is based on a semiconductor optical ampli…

Local Voronoi Computation and Sweep Line Intersection for Efficient Voronoi-Based Grouping Test Localization in Wireless Sensor Networks ↗
Node localization is a fundamental service in wireless sensor networks (WSNs), and range-free schemes such as the Voronoi diagram-based grouping test localization (VTL) achieve good accuracy without distance measurements. However, VTL repeatedly constructs Voronoi diagrams over all anchor nodes of each group and resolves the intersection of positive regions by an exhaustive grid scan, which limits its scalability. This paper proposes and evaluates two optimizations: (1) a local Voronoi computation that restricts the computation to the k anchors nearest to the strongest-signal anchor (including…

Emerging Technologies in Granulation: Process Analytical Technologies and Modeling Approaches in Pharmaceutical Development and Manufacturing ↗
In the present review, 32 studies, published between 2020 and 2026, were reviewed to identify recent advances in pharmaceutical granulation. Emphasis is placed on the integration of real-time monitoring technologies, recent Process Analytical Technologies (PATs) approaches, the relationships between critical process parameters (CPPs) and critical quality attributes (CQAs) affecting the product, and continuous manufacturing, as well as the implementation of modern data processing models. Increased attention was paid to continuous granulation using twin-screw extrusion, alongside the use of spec…

Automated safety interpretation of crack-aperture for concrete dams using mutation-aware visual-sensor fusion and knowledge-augmented reasoning ↗
Automated safety interpretation of concrete-dam cracks remains challenging because crack-gauge records may be incomplete, abnormal changes are difficult to distinguish from normal evolution, and monitoring outputs are not readily translated into traceable decisions. This paper proposes a mutation-aware visual–sensor fusion and knowledge-augmented framework. A deep learning model, multiscale dynamic spatial YOLOv11n (MDS-YOLOv11n), extracts crack widths from images and aligns them with crack-gauge measurements to supplement missing observations. Autoformer models the fused sequence; a dynamic t…

Pulse-Generation Maps in External-Cavity Semiconductor Lasers with Short-Delay Optical Feedback ↗
We investigate pulse generation in external-cavity semiconductor lasers subject to short-delay optical self-feedback using a deterministic quadrature-based delay-differential model. High-resolution pulse-generation maps are constructed in the (lg(C),ϕf) parameter space, where lg(C)≡log10(C), for pump ratios μ=4, 6, 8, and 10, where μ=J/Jth. For each pump level, the feedback delay is normalized to the solitary-laser relaxation-oscillation period and set to τf/TR=0.5 and 1, providing a physically consistent basis for comparing pulsing regimes across operating conditions. Post-transient intensity…

The E80 Microworld: A Gate-Transparent VHDL CPU and One-Click Toolchain ↗
The E80 is an open-source, 8-bit, single-cycle soft processor written in VHSIC Hardware Description Language (VHDL) from gates, multiplexers, and flip-flops, without an arithmetic package. Its 39 instructions were derived from 371 program samples in eight sources of introductory computer architecture material. They cover almost 80% of the operations recorded, averaged per source. A toolchain takes an assembly program to a simulation waveform with one keystroke. Presets cover three low-cost field-programmable gate array (FPGA) boards, one on a fully open-source flow. This extended version remov…

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.
