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.
Recent 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 nuclear Argonaute HRDE-1 broadly interacts with euchromatin via an RGG domain to enable transgenerational epigenetic silencing ↗
Small RNA(sRNA)-guided transcriptional repression, a process termed as nuclear RNAi, safeguards genome integrity and germline development. Central to this pathway are the highly conserved Argonaute (AGO) proteins, which are guided by sRNAs to mediate transcriptional silencing and heterochromatin formation at the target locus. The mechanism of how nuclear AGO proteins engage chromatin remains poorly understood. By studying C. elegans nuclear AGO HRDE-1, we found that an intrinsically disordered arginine-glycine-glycine (RGG) domain in HRDE-1 is essential for siRNA-guided transgenerational epige

Aspects of Symmetry in Nuclear Quantum Computing Variational Algorithms ↗
Variational Quantum Eigensolvers (VQEs) have become a standard tool for use in preparing eigenstates in quantum simulations of many-body systems. In the case of the nuclear shell model, various adaptations of the VQE have been shown to be able to produce ground and excited states of nuclei. The VQE algorithm works by seeking minima in a cost function, which is often the expectation value of the energy. For a well-formulated problem, symmetries that are respected by the Hamiltonian should appear in the final converged solution provided by the VQE, even if those symmetries are broken by the wave…

Actin Remodeling in Skeletal Myogenesis from Nuclear Signaling to Myoblast Fusion ↗
Actin remodeling accompanies myoblast proliferation, lineage commitment, elongation, fusion, and myofibril assembly, but these changes do not constitute a single linear pathway. This review separates three experimentally distinguishable scales of actin function in skeletal myogenesis. First, the balance between monomeric and filamentous actin controls myocardin-related transcription factor–serum response factor (MRTF–SRF) signaling and thereby couples cytoskeletal state to gene expression. Second, integrin–focal adhesion kinase (FAK)–Rho signaling and actomyosin tension influence Yes-associate…

Discordant Chloroplast and Nuclear Divergence Among Eight Rubus crataegifolius (Rosaceae) Cultivars ↗
Background: Cultivar identification and the reconstruction of breeding relationships require markers that reflect both parents, yet plastome sequencing is often applied to these problems on its own. Methods: We tested how far chloroplast data alone can go in Rubus crataegifolius Bunge, using one plant of each of eight cultivars from Korean breeding programs. Complete chloroplast genomes (155,664–155,770 bp) were assembled for all eight and compared with nuclear resequencing data from the same plants. Results: The 526 plastome variants were concentrated in non-coding regions, and Ka/Ks ratios w…

Identification of single-copy nuclear PCR targets for resolution of species-scale clades: a proof-of-concept using eupulmonate gastropods ↗
Abstract To aid in the empirical evaluation of species hypotheses / concepts we present a strategy that uses NGS whole nuclear genome assemblies to identify novel single-copy universal PCR targets whose sequences discriminate species-scale clades. Our approach begins by identifying UCEs within partial Illumina genome assemblies across a strategically-chosen taxa set and culminates with experimental validation of appropriate single-copy nuclear DNA regions for PCR/Sanger sequencing. The highly diverse (~ 35 K species) group of eupulmonate gastropods was used as proof-of-concept. Among the ~ 24…

Intelligent Parameter Tuning Strategy for Nuclear Power Simulation Systems Based on Soft Actor–Critic ↗
The effective tuning of extensive, high-dimensional parameter sets within nuclear power simulation systems presents considerable challenges for conventional, experience-based methodologies. Such approaches often exhibit limitations including slow convergence rates, susceptibility to local optima, and inadequate adaptability across diverse scenarios. This study introduces an automated parameter tuning strategy employing the Soft Actor–Critic (SAC) reinforcement learning approach. A SAC-based agent is formulated, where state representations, action spaces, and reward functions are specifically d…

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.
