Earlier sources: Nuclear
This energy thread follows nuclear through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
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 ↗59 classified signals in the fourteen-day window. 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.

The ePESSTO+ census of ZTF nuclear transients. I. What flares in galactic nuclei? ↗
Transients in galactic nuclei arise from distinct processes, only some of which trace the supermassive black hole (SMBH). These include tidal disruption events (TDEs), changing-look active galactic nuclei, Bowen fluorescence flares (BFFs) and ambiguous nuclear transients, alongside supernovae that appear nuclear but are unrelated to the SMBH. Reliable classification requires spectroscopy, which will not scale to the alert volumes of the Legacy Survey of Space and Time (LSST). We aim to characterise the population of nuclear transients, to identify early observables capable of distinguishing SM…

Probing Lithium Metal Microstructures with Dynamic Nuclear Polarization from Lithium Metal ↗
Abstract Lithium metal batteries (LMBs) show strong potential for next-generation energy storage, because of their high theoretical energy density. However, their practical deployment is limited by microstructure and dendrite formation, which raises serious safety and efficiency concerns. A key factor influencing dendrite growth is the passivating film, or solid electrolyte interphase (SEI), that forms at the lithium metal surface. Gaining insight into the SEI is essential for controlling dendrite formation, yet this remains challenging due to its complex composition and disorder. Lithium meta…

Radiological characterization for research reactor decommissioning: Application of lessons learned from the VVR-S reactor to the WWR-M facility ↗
Radiological characterization is a key element of the decommissioning of any nuclear facility, providing the information required for dismantling planning, radiation protection, radioactive waste management, and final site release. This paper presents a characterization strategy developed for the decommissioning of the WWR-M research reactor in Ukraine, integrating historical records, radiological surveys, in situ measurements, laboratory analyses, activation assessments, and radionuclide inventory determination. The proposed approach covers three main stages of decommissioning: dismantling, r…

How Multivariate Design of Experiments and Feature Extraction Strategy Can Support the Understanding of Time Domain Nuclear Magnetic Resonance Signals from Complex Elastomeric Systems ↗
Abstract Time domain nuclear magnetic resonance (TD-NMR) is a nondestructive analytical technique increasingly used for the characterization of rubber products. Its growing adoption is due to the nature of the acquired signal, which consists of a time-dependent decay strongly correlated with the polymeric mobility of the analyzed materials. Consequently, any factor influencing polymeric mobility also affects the TD-NMR signal, making it essential to understand the impact of these factors for routine application of the technique. To this aim, a multivariate design of experiment (MDoE) approach…

Response Amplification Analysis Based on Seismic Performance Tests of Electrical Components Incorporating the In-Cabinet Response Spectra of a Nuclear Power Plant Electrical Cabinet Model ↗
Evaluating the seismic performance of safety-related electrical equipment is crucial for limiting severe damage caused by major disasters at nuclear power plants (NPPs). In this study, various electrical components used in multiple Korean NPPs underwent seismic performance tests in accordance with IEEE Std 344, considering the dynamic characteristics of their mounting equipment and the in-cabinet response spectrum (ICRS) at each mounting location. Electrical components demonstrated satisfactory seismic performance and met the acceptance criteria for electrical functions specified in IEEE Std C…

A Bayesian regularized MLEM hybrid approach for reactor fast-neutron spectrum adjustment ↗
Precise characterization of the fast-neutron energy spectrum constitutes a fundamental requirement for evaluating radiation damage in reactor pressure vessels (RPV). Conventional MLEM iterative adjustment algorithms applied to high-precision spectrum adjustment often result in potential spectral artifacts due to the inability to rigorously propagate off-diagonal covariance terms. A novel Bayesian Regularized Maximum Likelihood Expectation Maximization (BR-MLEM) framework is proposed to address these challenges by integrating hierarchical Bayesian priors with adaptive regularization. This metho…

Range-Wide Nuclear Phylogeography of the Aesculapian Snake (Zamenis longissimus) and the Evolutionary Significance of a Northern Relict River-Valley Population System ↗
Background/Objectives: Relict populations can preserve genetic legacies that illuminate species history and inform conservation. Isolated northern populations of the Aesculapian snake (Zamenis longissimus) are considered remnants of a broader Holocene distribution, offering an opportunity to explore historical population connections and their conservation significance. We assessed diversity in Czech populations and provide the first range-wide phylogeographic perspective based on the nuclear marker SPTBN1. Methods: We analyzed mitochondrial DNA (mtDNA) and SPTBN1 in Czech populations, includin…

Nuclear blebs are composed of variable chromatin states and display increased transcription initiation relative to elongation ↗
Nuclear blebs are herniations of the nucleus that occur in many human conditions including aging, heart disease, muscular dystrophy, and many cancers. Nuclear blebbing causes nuclear rupture and cellular dysfunction. However, understanding the formation, stability, and identification of nuclear blebs remains an ongoing challenge. Our previous studies reveal that nuclear blebs are best hallmarked by decreased DNA density. To determine if chromatin decompaction underlies decreased DNA density in nuclear blebs, we investigated the histone composition of nuclear blebs across multiple cell lines. T…

How to assess evidence about Nuclear
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.
