"Zo neemt het gebruik van groene stroom minder snel toe dan verwacht, schrijft demissionair minister Hermans van Groene Groei en Klimaat (VVD) in een Kamerbrief.
Voornaamste oorzaak is dat de verduurzaming van de industrie moeizaam verloopt en fabrieken dus langer gebruik moeten maken van fossiele brandstoffen als olie, aardgas en steenkool."

Kabinet snoeit flink in plannen voor windenergie op de Noordzee
Na veel slecht nieuws over windenergie op zee stelt het demissionaire kabinet het streefdoel officieel naar beneden bij.

Zhu algebras of superconformal vertex algebras
The purpose of this note is to demonstrate the advantages of Y.-Z.\ Huang's definition of the Zhu algebra (Comm.\ Contemp.\ Math., 7 (2005), no.\ 5, 649--706) for an arbitrary vertex algebra, not necessarily equipped with Hamiltonian operators or Virasoro elements, by achieving the following two goals: (1) determining the Zhu algebras of $N=1,2,3,4$ and big $N=4$ superconformal vertex algebras, and (2) introducing the Zhu algebras of $N_K=N$ supersymmetric vertex algebras.

Origin of Reverse Size Effect in Ferroelectric Hafnia Thin Films
The persistence of ferroelectricity in ultrathin HfO$_2$ films challenges conventional theories, particularly given the paradoxical observation that the out-of-plane lattice spacing increases with decreasing thickness. We resolve this puzzle by revealing that this anomalous lattice expansion is counterintuitively coupled to suppressed out-of-plane polarization. First-principles calculations combined with analytical modeling identify two mechanisms behind this expansion: a negative longitudinal …

Draw a Portrait of Your Graph Data: An Instance-Level Profiling Framework for Graph-Structured Data
Graph machine learning models often achieve similar overall performance yet behave differently at the node level, failing on different subsets of nodes with varying reliability. Standard evaluation metrics such as accuracy obscure these fine grained differences, making it difficult to diagnose when and where models fail. We introduce NodePro, a node profiling framework that enables fine-grained diagnosis of model behavior by assigning interpretable profile scores to individual nodes. These scor…

CharaConsist: Fine-Grained Consistent Character Generation
In text-to-image generation, producing a series of consistent contents that preserve the same identity is highly valuable for real-world applications. Although a few works have explored training-free methods to enhance the consistency of generated subjects, we observe that they suffer from the following problems. First, they fail to maintain consistent background details, which limits their applicability. Furthermore, when the foreground character undergoes large motion variations, inconsistenc…

Large ferromagnetic-like band splitting in ultrathin ${\mathrm{SmC}}_{6}$ films
Two-dimensional (2D) magnetic materials provide a unique platform for exploring quantum phases from magnetic order in reduced dimensions. While there have been extensive studies on 2D magnetic materials based on 3$d$ electrons, experimental studies on 4$f$-electron counterparts are far fewer, particularly on their electronic structure. In this study, we report the successful synthesis of ultrathin ${\mathrm{SmC}}_{6}$ films using molecular beam epitaxy. Utilizing in situ angle-resolved photoemi…

Holey sheets: Double-Threshold Rupture of Draining Liquid Films
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scale where these molecular forces act, yet the mechanism that selects opening versus healing has remained unclear. Using direct numerical simulations of a draining sheet with an entrained air bubble (cavity), we show that irreversible rupture occurs only when a deterministic double-threshold is crossed: (i) the outward d…

Quantitative 3D Morphology of Cellular H2/O2/N2 Flames on a Porous-Plug Burner: Spatially Resolved Measurements of Temperature and OH Radical
This study presents a systematic characterization of burner-stabilized lean hydrogen flame morphology across a wide range of equivalence ratios, dilution factors, and flow rates. Spatially resolved measurements of three-dimensional temperature and OH distributions were achieved. A comprehensive dataset of over 200 flame cases was obtained, enabling accurate determination of regime diagrams for different flame modes. Linear stability analysis and direct numerical simulations were also performed …
