Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
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 ↗722 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.

Energy-aware scheduling approach for enhanced performance of parallel applications in simulated heterogeneous cloud environments ↗
Energy-constrained workflow scheduling seeks to minimize application makespan while preserving a finite energy budget across heterogeneous DVFS-enabled resources. Existing pre-assignment methods generally distribute energy using a single task-level criterion, which can restrict the VM–frequency choices of later tasks when the budget is tight. This paper proposes the Energy-Aware Scheduling Approach (EASA), whose core scheduling procedure combines four elements: a normalized dual-factor surplus-energy allocation based on both minimum computation cost and minimum energy demand; explicit reservat…

A resource-aware framework for energy and bandwidth efficient IoT intrusion detection using lightweight federated learning over SDN ↗
The rapid growth of Internet of Things (IoT) deployments has widened the network attack surface while increasing the cost of centralised intrusion detection, particularly when raw traffic must be moved to remote servers. We propose HFL-SDN-IDS, a hierarchical, resource-aware framework that combines a lightweight federated intrusion-detection model, two-tier aggregation, and an SDN-assisted enforcement layer. The contribution is a system-level co-design rather than a new federated aggregation rule. Experiments use five benchmark datasets-CICIDS-2017, N-BaIoT, TON_IoT, Edge-IIoTset, and UNSW-NB1…

Effective power and energy utilization analysis of a dual-motor electric tractor under battery current limitations ↗
This study evaluated the effective power and energy utilization characteristics of a dual-motor electric tractor under simultaneous power take-off (PTO) and traction operating conditions. Experimental measurements were conducted using Organization for Economic Cooperation and Development (OECD) Code 2 PTO and drawbar traction tests to characterize the performance of the tractor and its electrical power system. Effective power was defined as the combined usable output of the PTO and traction systems while considering allowable battery current limitations. Battery current, energy consumption, en…

Stability assessment of abandoned salt caverns for compressed air energy storage – a study based on true triaxial mechanical test ↗
The utilization of abandoned salt rock caverns for energy storage has emerged as a novel and promising approach. Relying on a CAES project in salt rock in Feicheng, Shandong Province, a series of true triaxial mechanical experiments were carried out on overburden, reservoir and interlayer rock, and the mechanical parameters consistent with the actual engineering conditions were obtained. Furthermore, based on stratigraphic characteristics and three-dimensional seismic data, a three-dimensional mechanical model of abandoned salt cavern group considering the effect of intermediate principal stre…

Techno-economic optimization and hybrid deep learning-based net-load forecasting for intelligent microgrid energy management using HOMER Pro ↗
Abstract The integration of renewable energy resources into electrical grids has increased the need for replicable and cost-effective microgrid design and operation strategies. This paper presents a microgrid planning and energy management framework that combines HOMER Pro-based techno-economic optimization with hybrid deep learning-based forecasting. First, three microgrid configurations comprising photovoltaic (PV) generation, battery energy storage, diesel generation, and grid interconnection are modeled and evaluated based on economic, operational, and environmental performance. The optima…

Inverse relationship between mitochondrial and non-coding nuclear DNA content in free-living kinetoplastids ↗
The evolution of genome size and eukaryotic genome organisation has puzzled evolutionary biologists for decades. Are differences in DNA content and protein-coding capacity of eukaryotic genomes a result of natural selection, or neutral processes? If they were shaped by natural selection, which features might be connected with these differences: cell volume, ecological strategy, availability of nutrients, etc.? Kinetoplastids are protists with compact nuclear genomes that almost entirely lack introns, but whose mitochondrial DNA content (kDNA) can rival that of their nuclei. We hypothesised tha

Chromatin-associated intronic RNAs from long genes form introsomes that shape nuclear architecture in neuronal cells ↗
Abstract Cell differentiation towards neurons is accompanied by widespread changes in three-dimensional (3D) genome organization and gene expression. Chromatin-associated RNAs have been proposed to be important regulators of such changes; however, the type, abundance, and role of these RNAs during neuronal differentiation remain largely unexplored. Here, we integrate multi-omic data generated in the frame of the Functional ANnoTation Of the Mammalian genome (FANTOM6) to chart 3D genome, RNA-DNA contactome, and transcriptome changes occurring during in vitro differentiation of human induced plu

Analytic non-axisymmetric 3D MHD equilibria without stellarator symmetry ↗
Analytical solutions to the three-dimensional ideal magnetohydrodynamic equilibrium equations $(\nabla \times \vec{B}) \times \vec{B} = \nabla p$ and $\nabla \cdot \vec{B} = 0$ provide benchmarks for stellarator equilibrium codes. Two families of non-axisymmetric solutions were recently discovered by Landreman [arXiv:2609.26742] as counterexamples to Grad's conjecture, but both satisfy stellarator symmetry. Here, we generalize both families by introducing a symmetry-breaking parameter into each of the solutions, resulting in new non-axisymmetric solutions that break stellarator symmetry and re…

Boundary-accessible work in a collision-charged topological quantum battery ↗
Quantum batteries store energy in nonequilibrium quantum states. The ergotropy sets the work extractable by an arbitrary global unitary, but a device usually exchanges energy through a single local port. It remains unclear how much stored work such a port can deliver, and whether topological edge modes help. We study a dimerized spin chain of Su-Schrieffer-Heeger (SSH) type. Excited two-level ancillas charge it at one end by repeated collisions, and an initially empty two-level load discharges it at the same site. An exact free-fermion mapping yields a bound on the load work for all number-con…

How to assess evidence about Energy
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.
