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 ↗732 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.

An active recommendation algorithm for trade union rights and interests services in power grid enterprises based on knowledge graphs and dynamic user personas ↗
Proactive recommendation of trade union rights and interests services is essential for improving service precision and responsiveness in power grid enterprises. Existing service models often rely on manual processing or static rule matching and therefore have limited capacity to capture employees' changing needs across job roles, policy contexts, and service scenarios. To address this limitation, this study proposes an active recommendation algorithm that integrates a domain knowledge graph with dynamic user personas. The framework constructs the knowledge graph through enhanced entity recogni…

State of charge estimation for lithium-ion battery balancing systems considering branch current dynamics under non-ideal switching ↗
State-of-charge (SoC) estimation is essential for lithium-ion battery management systems. In practical battery packs, balancing circuits are commonly used to reduce cell inconsistency. However, most existing balancing-aware methods treat the balancing branch as an ideal binary switch and directly determine the balancing current from the switching command. This simplification neglects branch-current dynamics under non-ideal switching, which may introduce mismatch in cell-current reconstruction and reduce estimation accuracy. To address this issue, this paper proposes an SoC estimation method fo…

A feature selection and model fusion framework for lithium-ion battery state of health estimation under capacity regeneration phenomena ↗
Data-driven models have been widely employed for the state of health (SOH) estimation of lithium-ion battery in recent years. However, during long-term aging, batteries are prone to exhibiting significant capacity regeneration amidst the normal capacity fading. Traditional data-driven methods cannot efficiently extract features that reflect the localized behavior, and the single estimation model also fails to capture complex aging behaviors, leading to a decline in SOH estimation accuracy. To address the issues, this paper proposed an SOH estimation framework that combines a feature selection…

Dynamics and Energy Relaxation of Formic Acid Dimers Following Inner Valence Ionization ↗
Abstract We study gas-phase dissociation of the formic acid dimer dication as a model for DNA base-pair interactions after inner-valence 56 eV extreme ultraviolet (EUV) ionization. Employing reaction microscopy, we measure the 3D momenta of electrons and fragment-ions in coincidence to reconstruct channel-resolved electron kinetic energies, fragment kinetic energy release, and angular distributions. This work focuses on the symmetric 2-body (HCOOH+ + HCOOH+) and asymmetric 3-body (HCOOH+ + HCOO+ + H) breakup channels, reporting their relative yields and dynamics. Electron-energy signatures and…

Optimization and feasibility of hybrid photovoltaic-thermal and wind turbine along with forced convection phase change material-embedded Trombe wall using control algorithm for targeting Net Zero Energy Buildings ↗
The objective of this study is to economically optimize a grid-connected hybrid renewable energy system, comprising a wind turbine (WT) and photovoltaic–thermal (PV/T), that allows the forced convection phase change material (PCM)-embedded Trombe wall building (PCMTWB) which is conditioned by ground source heat pump (GSHP) to target net zero energy building (ZEB) status. Since the Trombe wall is modeled as forced convection, a control algorithm is used to prevent its negative effects. Classical Trombe wall building (CTWB) and PCMTWB against the standard building (SB) across the four distinct c…

In the context of power market development, the power demand of computing power enterprises is on the rise. As an important link, the operation mode of virtual power plants (VPP) affects the power market and the growth of new energy power generation, and is restricted by many factors, such as thermal power costs. From the perspective of the power supply chain, this paper establishes a model that includes energy producers, VPP (Power Type, Load Type, and Energy Type) and computing power enterprises, introduces the differential game strategy, and studies the impact of different factors on new en…

Oriented composite phase change material with high thermal conductivity at low filler loading for battery thermal management ↗
Conventional phase change materials (PCMs) use thermally conductive fillers to improve thermal conductivity and mitigate battery temperature rise. However, excessive filler addition inevitably weakens energy storage components and reduces the latent heat of phase change, making it challenging to balance thermal conductivity and latent heat. In this study, hexagonal boron nitride (h-BN) and spherical aluminum oxide (Al 2 O 3 ) were used as thermally conductive fillers, and paraffin (PA) served as the phase change matrix. An oriented composite phase change material (OCPCM) possessing both high t…

Codon-aware multi-scale feature fusion for metagenomic sequence classification ↗
Microorganisms exert profound influences on both natural ecosystems and human society. As the cornerstone of microbial research, metagenomics relies on the precise analysis of large-scale, multi-source genomic data. However, discriminating among diverse sequence types remains a formidable challenge. To address this, we present CamFi (Codon-aware Multi-scale Feature Fusion), a unified framework integrating overlapping nucleotide-triplet representations with multi-scale dilated convolutions for classifying prokaryotic chromosomes, eukaryotic chromosomes, plasmids, and viruses. Benchmark evaluati…

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.
