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.

Anvaya: phylogenomic analysis of chromosome fusion-and-mixing characters and detection of shared whole-genome duplication ↗
Chromosome-scale conservation of gene linkage (macrosynteny) provides phylogenetic characters largely independent of sequence data. Fusion of ancestral linkage groups, and especially the subsequent interspersion (mixing) of their genes, is argued to be effectively irreversible, and such synapomorphic events have been used to resolve deep, contentious nodes. I present Anvaya, a dependency-light, open-source toolkit of two Python programs with companion threshold-calibration tools which takes reciprocal-best-hit (RBH) synteny data directly to a phylogenetic analysis that codes fusion and mixing

Compressional heating above 1 keV on the LM26 magnetized target fusion machine ↗
The LM26 device has achieved a peak electron temperature of $T_e = 1180 \pm 65$ eV as measured by filtered X-ray diodes, supported by adjacent Thomson scattering measurements of $T_e = 1090 \pm 40$ eV, with a deuterium ion temperature of $T_i = 459 \pm 33$ eV as inferred from neutron yield. LM26 compresses a spherical tokamak plasma inside an initially 1.76 m diameter solid lithium liner imploded by theta-pinch coils. Radial compression by a factor of 2.75 increases $T_e$ over fivefold, while $T_i$ increases as much as twofold. The integrated observation of magnetic flux compression, electron…

Imaging ablator-fuel mix of hot spot in inertial confinement fusion via resonant X-ray absorption using an X-ray free electron laser ↗
A novel diagnostic is proposed for active probing of doped inertial confinement fusion (ICF) spherical shells, enabling direct measurements of mix and burn dynamics at next-generation implosion facilities via resonant absorption imaging with an X-ray free-electron laser (XFEL). The charge-state-sensitive imaging of embedded dopants provides spatiotemporally resolved constraints on ionization, opacity, and material mix seeded by hydrodynamic instabilities in stagnated plasmas. Proof-of-principle experiments demonstrating resonant XFEL probing of hot spot in coated copper wires driven by an ultr…

Reaching high fusion gain with grams of spin-polarized fuel ↗
Building on recent ignition-access work of Delgado-Aparicio, Ono, and Menard, we show that even a single-use, gram-scale quantity of spin-polarized fuel (SPF) is useful for increasing fusion power and gain in magnetic confinement fusion machines such as tokamaks and stellarators. While fueling a fusion power plant continuously with SPF requires $\sim$kilograms per day, far beyond present capabilities, a single-use short pulse of SPF allows a fusion plasma to cross into a high-gain regime, and stay there, even after switching back to regular unpolarized fuel. With continuous polarized fueling,…

Beam filamentation instability drives deuterium-tritium fusion with polarized neutron emission ↗
Filamentation instabilities are generally regarded as detrimental to fast-electron transport in fusion plasmas because they increase beam divergence and redistribute deposited energy. Here, we use two-dimensional particle-in-cell simulations coupled to a spin-dependent deuterium-tritium fusion module to investigate whether filamentation can instead transfer energy from counterstreaming electrons to prepolarized fusion ions. The simulations show that magnetic filaments, together with longitudinal inductive and transverse charge-separation electric fields, accelerate initially stationary deutero…

On Porosity Analysis of Ti-6Al-4V Thin Struts Made by Laser Powder-Bed Fusion: Effects of Build Orientation, Strut Size and Linear Energy Density ↗
Porosity in laser powder bed fusion (L-PBF) lattice struts remains poorly understood, as the effects of build angle and process parameters are often studied separately. A full factorial design of 27 configurations combined three build angles (40–70°), three strut sizes (0.25–1.25 mm), and three linear energy densities (LED: 0.23–0.35 J/mm). Specimens were fabricated in Ti-6Al-4V on an EOS M270 system and characterized by micro-computed tomography (µ-CT). Statistical analysis showed that all three factors influenced porosity percentage (P%), with a significant size–LED interaction, while only s…

SCANs: Frequency-Domain Spectrum Channel Attention for LiDAR–Camera Fusion in 3D Object Detection ↗
LiDAR–camera fusion has become a widely adopted paradigm for 3D object detection in autonomous driving by effectively leveraging the complementary geometric and semantic information provided by the two sensing modalities. However, most existing fusion methods primarily emphasize cross-modal fusion strategies while relying on conventional feature extraction networks, where global average pooling (GAP) inevitably discards high-frequency information and consequently limits the representation of fine-grained details and long-range contextual dependencies. To address this limitation, we propose Spe…

MSAFP-Net: An Adaptive Fusion-Driven Multi-Scale Neural Network for Peak Production Forecasting in Gas Wells ↗
This study seeks to overcome the limitations of traditional gas well production peak forecasting approaches, particularly in the context of handling multi-dimensional features, complex dynamic behaviors, and non-linear relationships. Accordingly, a deep learning-based multi-scale adaptive fusion perception network is proposed in this work. Specifically, a time-series processing framework based on multi-scale decomposition is first constructed, where wavelet transform is employed to perform multi-scale decomposition of the gas well production data, thereby effectively extracting both long-term…

Ultra-compact amyloidogenic fusion tags mediated efficient production of liraglutide precursors and molecular insights ↗
Abstract The recombinant production of therapeutic peptides such as the glucagon-like peptide-1 (GLP-1) analogue liraglutide precursor in E. coli is often constrained by peptide instability, susceptibility to intracellular proteolysis, and the use of large fusion partners that reduce the target peptide mass fraction and impose a metabolic burden on the host. Here, we developed a minimalist fusion strategy employing ultra-compact short amyloidogenic peptides (SAPs) as multifunctional fusion tags that consolidate aggregation-inducing, affinity-capture, and protease-cleavage functionalities withi…

Geotechnically Informed Monitoring-Data Fusion and Gradient-Boosted Regression for Instrumented Driven Piles ↗
Long-term monitoring can test whether pile-design assumptions remain appropriate as consolidation and soil-pile load transfer develop after construction. This study combines records from three Ontario transportation projects: Ramsayville, Locha Creek, and Nash Road. The database contains 53,218 weekly movement records, 152 sensor channels, 1714 axial-load profiles, and ten instrumented piles. Baseline-referenced axial-force changes were interpreted together with pore pressure, ground and pile movement, soil-test results, pile geometry, load tests, and construction history. Conventional total-s…

How to assess evidence about Fusion
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.
