Joint extraction of space target micro-motion parameters at low SNR based on consistency variational autoencoder and cascaded transformer

Micro-Doppler technology has significant applications in the recognition of space non-cooperative targets. However, in practical radar detection, background noise caused by low signal-to-noise ratios and the nonlinear coupling among various micro-motion parameters limit the featu...

Demand-weighted edge betweenness centrality for identifying critical pipes in water distribution networks

ABSTRACT Graphical abstract summarising the DWEBC workflow: a WDN is converted to a weighted graph; EPANET hydraulic outputs and demand data are used to compute DWEBC; and high-ranking pipes support resilience screening, maintenance prioritisation, and digital-twin decision-makin...

Multiscale‐Guided Molecular Engineering of Aromatic Charge‐Trap Epoxy Dielectrics for Synergistic Electro–Hygro–Thermal Resilience

ABSTRACT Escalating demands of modern high‐voltage power grids necessitate epoxy‐based electrical insulation materials with simultaneously enhanced dielectric withstand capability, moisture resistance, and thermal durability. A multiscale molecular design strategy integrating fir...

Response and modeling of axially-loaded concrete-filled steel tubular columns with coal gangue coarse and fine aggregate

Concrete-filled steel tubular columns with coal gangue aggregate (GACFST) present a sustainable solution for the structural use of coal mining waste. However, the existing studies have only studied the effects of coal gangue coarse aggregate (CGA) or fine aggregate (FGA) alone, w...

MultiSpaceNet: Graph-based Joint Representation Learning for Paired Spatial Transcriptome–Proteome Data

MOTIVATION: Paired spatial assays now measure the transcriptome and the proteome on the same tissue section. Existing integration methods commit to a structural choice at the outset: a separate graph per modality, early fusion that folds the measured protein into the embedding so...

Study on the vortex-induced Helmholtz resonance with a cylindrical roof opening via high-order dynamic mode decomposition

The vortex-induced Helmholtz resonance (VIHR) is one special phenomenon of the internal pressure response due to the coupling of normal Helmholtz resonance and vortex shedding around the opening. In order to investigate the behavior of the VIHR, the wind tunnel test is conducted...

Design strategies for multifunctional magnesium alloy coatings in marine environments: Coupling corrosion resistance, superhydrophobicity and antifouling

Magnesium alloys are increasingly attractive for marine applications due to their low density and high specific strength; however, their inherent susceptibility to corrosion and biofouling severely restricts long-term performance. The simultaneous integration of corrosion resista...

Lattice Boltzmann Modeling of Electro‐Thermo‐Convection in Dielectric Liquids With Electric Conduction

ABSTRACT This paper develops a two‐relaxation‐time lattice Boltzmann method (TRT‐LBM) framework for simulating electro‐thermo‐convection (ETC) driven by conduction‐based charge transport in a two‐dimensional sidewall‐heated square cavity. The coupled flow, temperature, and charge...

Governing Digital‐Green Transitions: A Configurational Synthesis of Employment Outcomes

ABSTRACT Digital transformation and environmental sustainability are often framed as mutually reinforcing, yet their employment effects remain uneven across institutional and economic contexts. This study examines why digital transformation produces divergent employment outcomes...

st2traj: deconvolution-informed trajectory inference for multi-timepoint spatial transcriptomics

MOTIVATION: Multi-timepoint spatial transcriptomics enables study of developmental processes in native tissue context, but cell-state mixtures within spots and lack of direct spatial correspondence across sections complicate trajectory inference and biological interpretation. RES...

Photovoltaic systems in the Nordics: A systematic review of techno-economic and life-cycle sustainability assessments

The rapid global deployment of photovoltaic (PV) technologies has increased the need for comprehensive evaluations of their technical performance, economic viability, and environmental compatibility. At high-latitudes, these assessments are essential due to low solar elevation an...
