• ELEVATE-ID: Extending Large Language Models for End-to-End Entity Linking Evaluation in Indonesian. Gusmita, Ria Hari; Firmansyah, Asep Fajar; Zahera, Hamada M.; Ngonga Ngomo, Axel-Cyrille (2026). 161 102504.

  Large Language Models (LLMs) have demonstrated remarkable performance across a wide range of natural language processing tasks. However, their effectiveness in low-resource languages remains underexplored, particularly in complex tasks such as end-to-end Entity Linking (EL), which requires both mention detection and disambiguation against a knowledge base (KB). In earlier work, we introduced IndEL — the first end-to-end EL benchmark dataset for the Indonesian language — covering both a general domain (news) and a specific domain (religious text from the Indonesian translation of the Quran), and evaluated four traditional end-to-end EL systems on this dataset. In this study, we propose ELEVATE-ID, a comprehensive evaluation framework for assessing LLM performance on end-to-end EL in Indonesian. The framework evaluates LLMs under both zero-shot and fine-tuned conditions, using multilingual and Indonesian monolingual models, with Wikidata as the target KB. Our experiments include performance benchmarking, generalization analysis across domains, and systematic error analysis. Results show that GPT-4 and GPT-3.5 achieve the highest accuracy in zero-shot and fine-tuned settings, respectively. However, even fine-tuned GPT-3.5 underperforms compared to DBpedia Spotlight — the weakest of the traditional model baselines — in the general domain. Interestingly, GPT-3.5 outperforms Babelfy in the specific domain. Generalization analysis indicates that fine-tuned GPT-3.5 adapts more effectively to cross-domain and mixed-domain scenarios. Error analysis uncovers persistent challenges that hinder LLM performance: difficulties with non-complete mentions, acronym disambiguation, and full-name recognition in formal contexts. These issues point to limitations in mention boundary detection and contextual grounding. Indonesian-pretrained LLMs, Komodo and Merak, reveal core weaknesses: template leakage and entity hallucination, respectively—underscoring architectural and training limitations in low-resource end-to-end EL.11Code and dataset are available at https://github.com/dice-group/ELEVATE-ID.
• AI Benchmarks: Interdisciplinary Issues and Policy Considerations. Eriksson, Maria; Purificato, Erasmo; Noroozian, Arman; Vinagre, Joao; Chaslot, Guillaume; Gomez, Emilia; Fernandez Llorca, David (2025).

  Artificial Intelligence (AI) benchmarks have emerged as essential for evaluating AI performance, capabilities, and risks. However, as their influence grows, concerns arise about their limitations and side effects when assessing sensitive topics such as high-impact capabilities, safety and systemic risks. In this work we summarise the results an interdisciplinary meta-review of approximately 110 studies over the last decade, which identify key shortcomings in AI benchmarking practices, including issues in the design and application (e.g., dataset creation biases, inadequate documentation, data contamination, and failures to distinguish signal from noise) and broader sociotechnical issues (e.g., over-focus on text-based and one-time evaluation logic, which neglects multimodality and interactions). We also highlight systemic flaws, such as misaligned incentives, construct validity issues, unknown unknowns, and the gaming of benchmark results. We underscore how benchmark practices are shaped by cultural, commercial and competitive dynamics that often prioritise performance at the expense of broader societal concerns. As a result, AI benchmarking may be ill-suited to provide the assurances required by policymakers. To address these challenges, it is crucial to consider key policy aspects that can help mitigate the shortcomings of current AI benchmarking practices.
• GLIDE: Knowledge Graph Linking using Distance-Aware Embeddings. Becker, Alexander; Ngonga Ngomo, Axel-Cyrille; Sherif, Mohamed Ahmed (2025).

  The number of datasets on the web of data increases continuously. However, the knowledge contained therein cannot be fully utilized without finding links between the entities contained in these datasets. Equivalent entities can not be identified solely by checking the equivalence of IRIs because of the different origins and naming schemes of different data providers. Yet, such equivalences can be discovered by computing the similarity of their attributes. In this paper we propose GLIDE, an approach that links entities from two different datasets by embedding a joint model of these datasets enriched by additional relations describing the similarity of literals. The joint model is embedded into a latent vector space while paying attention to juxtaposing similar literals. We evaluate our approach against state-of-the-art algorithms using real-world datasets commonly used in link discovery literature. The results show that GLIDE outperforms all baselines on 5 of 7 datasets with perfect or near-perfect accuracy. Our approach achieves its best performance on datasets that feature several literals with similarities. Our experiments indicate that researchers should not only pay attention to equal literals in knowledge graph embedding but should also be aware of the distance between similar literals.

• Integrating the landscape scale supports SAR-based detection and assessment of the phenological development at the field level. Löw, Johannes; Hill, Steven; Otte, Insa; Friedrich, Christoph; Thiel, Michael; Ullmann, Tobias; Conrad, Christopher (2025). 6(161005) 17.

  Climate change and increasing weather and seasonal dynamics challenge agricultural landscapes. To cope with this challenge information on crop performance is key. This study presents a novel framework for bridging landscape-scale vegetation dynamics with field-level crop phenology using Sentinel-1 radar time series. Unlike previous approaches that focus on local algorithm optimisation or SAR feature selection, this work integrates two scales: (1) landscape patterns derived from annual distributions of time series metrics (TSMs) and (2) field-level phenology, both linked to growing degree days (GDD). TSMs were generated through breakpoint analyses over different smoothing intensities for Sentinel-1 polarisation (PolSAR) and interferometric coherence (InSAR) features, capturing crop, orbit and sensor-specific responses. The framework quantifies uncertainties inherent in both remote sensing and ground observations, and evaluates trackable progress (phenological stage detectability) and tracking range (GDD variance around stages) to assess accuracy under variable acquisition geometries, weather and smoothing parameters. Applied to the DEMMIN site (Germany), the analysis revealed consistent TSM-GDD relationships for wheat, rape, and sugar beet, with descriptors such as soil fertility and water availability explaining spatial patterns (R2 ≈ 0.8). Key novelties include the identification of low tracking ranges in drought years, the demonstration of the impact of orbit-specific incidence angles on monitoring fidelity, and the highlighting of Sentinel-1’s ability to resolve phenological variance across fragmented landscapes. By harmonising multi-scale SAR time series with agro-meteorological data, this approach advances transferable methods for operational crop monitoring, supporting precision agriculture and regional yield assessment beyond localised models.

• Tuning Spatial Distributions of Selection Pressure to Suppress Emergence of Resistance. Tunstall, Thomas; Madgwick, Philip G.; Kanitz, Ricardo; Möbius, Wolfram (2024).

  Control measures such as insecticides or antimicrobials are used to contain biological agents such as pathogenic bacteria and vectors of human and plant diseases, respectively. Following control measure application, a resistant subpopulation may eventually rise to such frequency that the control measure will be rendered ineffective: The timescale over which this occurs is the textquotelefteffective lifetimetextquoteright of the control measure. Prolonging this timescale relaxes urgency at which novel control measure needs to be developed. Spatial heterogeneity in control measure application can influence the rate at which resistance to the control measure evolves; in the agricultural context, this fact is exploited by distributing insecticides in mosaics across cropping regions in order to slow the rate of resistance evolution.Contemporary and historical modeling practices, which aim to inform agricultural practices, often employ assumptions which squeeze out the impact of the spatio-temporal heterogeneity endemic to nature. In this paper, we present a minimal model of continuous dispersal and spatio-temporal heterogeneity in selection pressure distribution which exhibits a novel dynamic: The spatial distribution of selection pressure may be tuned in order to minimize the initial rate at which resistance evolves, thus increasing the effective lifetime of a pesticide.Author summary There are many contexts in which humans apply control measures to biological agents: pesticides are applied in fields to kill the pests that damage crops, mosquito nests are distributed to prevent the spread of malaria, and cancer drugs are applied to kill off tumors in humans. These control measures are examples of textquoteleftselection pressurestextquoteright, which select against strains which are susceptible to them. If a mutation occurs which confers resistance, the control agent will select for the resistant strain, thus reducing the efficacy of the control agent as the frequency of resistance increases in the population. This necessitates more of the control agent to be applied, or for a novel control agent to be developed. The former may have unintended consequences on the local environment, and the latter is expensive and time-intensive. It is preferable to carefully tune how the control agent is applied - perhaps instead of one massive compact region of control measure application, it is better to apply the control measure over multiple smaller regions? Here, we use a toy model of motile organisms to demonstrate that an optimal distribution exists for a variety of scenarios.Competing Interest StatementThe authors have declared no competing interest.

• Computationally cost-efficient analysis of the flow behavior of twin-fluid atomizers using computational fluid dynamics. Shin, Girim; Gbadago, Dela Q.; Do, Yunjeong; Hwang, Sungwon (2024). 212 97–109.

  In industrial-scale operations, wet electrostatic precipitators (WESPs) are used to minimize particulate matter, employing atomizers such as single-fluid and twin-fluid atomizers (TFAs). While TFAs provide several benefits over single-fluid atomizers, quantifying their spray characteristics is more complex, necessitating comprehensive case studies to design the internal structure of the spray and achieve desired properties. This study employed computational fluid dynamics (CFD) to simulate the internal and external flow phenomena of TFAs in industrial-scale WESPs, aiming to facilitate various parametric studies by reducing the high computational costs associated with analyzing high-speed internal flows and particle dynamics within the spray system. To decrease computational costs, the simulation was divided into two parts using stepwise segregated scenarios: Part I focused on the high-cost internal flow analysis, examining the spatiotemporal evolution of internal flow until it is fully developed, followed by droplet size distribution estimation at the nozzle. Part II computed the external flow of the spray, assessed potential cost reductions by examining the interactions between dispersed droplets, and validated the spray angle, penetration, and coverage against experimental data. The segregated strategy employed mapping techniques to integrate the two parts seamlessly. The simulation results closely matched the experimental benchmarks for spray angle, penetration, and coverage within a minimal error margin (< 5 %), demonstrating the model’s accuracy in capturing actual spray phenomena in TFAs. This approach significantly reduced the computational cost by more than twentyfold compared to conventional one-step solvers, offering a viable method for conducting various case studies in spray CFD simulations.

  The liquid atomization process relies on the disturbance of the liquid surface by various forces. In the case of “flow-blurring” (FB) atomization, this is achieved by inducing flow instabilities near the liquid channel exit. In this study, we analyze the underlying dynamics of these coherent turbulent structures and their role in the primary atomization within the FB regime. For that purpose, Smoothed Particles Hydrodynamics (SPH) simulations have been conducted using alternative FB nozzle geometries at different operating conditions. An in-house developed visualization and data exploration platform (postAtom) was used to capture the time-resolved Lagrangian coherent structures (LCSs) via the finite-time Lyapunov exponent (FTLE) fields. Simulations were conducted at different gas/liquid momentum ratios at the nozzle exit by changing the mass flow rate of the gas phase and/or changing the position of the liquid injector. The effect of outer chamber design on the atomization performance is further assessed. The results indicate that the design of the mixing chamber can trigger an oscillatory behavior at the nozzle exit, which has a direct impact on the evolution of the micro-ligaments and the consecutive primary atomization. Comparisons between different operating points further reveal that FB atomization may not be achieved if the gas momentum is below a certain threshold value.

  This review summarizes the state of the art of flow blurring atomization, focusing both on fundamental aspects of this atomization mode as well as key observations made from applications of flow blurring. Flow blurring is an internal-twin fluid atomization method that offers effective interphase turbulent mixing and very fine liquid sprays. The features of this mode of liquid breakup make it attractive for applications in liquid fuel spray combustion, although it also offers potential benefits to applications requiring the atomization of non-Newtonian liquids, for example, such as in polymer filament manufacturing. This review concisely covers features of the internal nozzle flow of flow blurring atomizers, the effect of the orifice geometry on the spray, the behavior of the near-field spray region, the effect of liquid physical properties on droplet behavior, and general observations of reacting flow blurring sprays. Consistencies among the various research conducted is highlighted throughout the review, and this information, along with identified gaps in our understanding, is used to offer suggestions for future research.

• 3D-coupling of Volume-of-Fluid and Lagrangian particle tracking for spray atomization simulation in OpenFOAM. Heinrich, Martin; Schwarze, Rüdiger (2020). 11 100483-.

  Simulations of spray breakup are challenging due to a wide range of different length and time scales. While Volume-of-Fluid (VoF) is suited for the primary breakup, the secondary breakup and the dilute spray cloud is better resolved using a Lagrangian particle tracking (LPT) method. This publication proposes a 3D coupling between both models using the CFD software OpenFOAM to resolve the complete process of spray atomization. Combined with adaptive mesh refinement, the computational cost can be reduced significantly. The simulation of a fuel jet in crossflow demonstrates the accuracy and speedup of the proposed method.
• Progress in the Smoothed Particle Hydrodynamics Method to Simulate and Post-process Numerical Simulations of Annular Airblast Atomizers. Chaussonnet, G.; Dauch, T.; Keller, M.; Okraschevski, M.; Ates, C.; Schwitzke, C.; Koch, R.; Bauer, H.-J. (2020). 105(4) 1119–1147.

  This paper illustrates recent progresses in the development of the smoothed particle hydrodynamics (SPH) method to simulate and post-process liquid spray generation. The simulation of a generic annular airblast atomizer is presented, in which a liquid sheet is fragmented by two concentric counter swirling air streams. The accent is put on how the SPH method can bridge the gap between the CAD geometry of a nozzle and its characterization, in terms of spray characteristics and dynamics. In addition, the Lagrangian nature of the SPH method allows to extract additional data to give further insight in the spraying process. First, the sequential breakup events can be tracked from one large liquid blob to very fine stable droplets. This is herein called the tree of fragmentation. From this tree of fragmentation, abstract quantities can be drawn such as the breakup activity and the fragmentation spectrum. Second, the Lagrangian coherent structures in the turbulent flow can be determined easily with the finite-time Lyapunov exponent (FTLE). The extraction of the FTLE is particularly feasible in the SPH framework. Finally, it is pointed out that there is no universal and ultimate non-dimensional number that can characterize airblast primary breakup. Depending on the field of interest, a non-dimensional number (e.g. Weber number) might be more appropriate than another one (e.g. momentum flux ratio) to characterize the regime, and vice versa.

  A twin-fluid pneumatic injector system with coaxial liquid and air streams mixed slightly upstream of the outlet, is studied in a cross-flow arrangement to understand its working principle. The gap between the orifice and the liquid tube, where the air and liquid cross-flow occurs, is known to determine the modes of working of the atomizer for the given operating flow rates of air and liquid. The two distinct modes, namely the flow focusing (FF) and flow blurring (FB) are observed in the present study, and the transition from FF to FB mode is explored using optical visualization. The characteristics of the internal two-phase flow mixing that occurs due to backflow recirculation in FB mode are also investigated by performing large eddy simulation (LES) using the volume of fluid (VoF) approach. The results of the numerical simulation are validated with experimental observations for the length of backflow recirculation observed in the liquid tube. The present study demonstrates the development of multiple microjets, which explains experimental observations of the lack of core jet and the almost uniform distribution of radial Sauter mean diameter (SMD) reported in the literature. The high-resolution backlit image of a scaled-up transparent injector with a 6 mm orifice diameter validates the numerical results that describe the internal two-phase flow.

  In the context of biofuel production, a twin-fluid atomizer is investigated by the means of the Weakly-Compressible Smoothed Particle Hydrodynamics (WCSPH) method. This configuration consists of a round liquid jet discharging at low velocity into a quiescent cavity. The liquid is atomized by a high-speed turbulent co-flow. This configuration has been studied experimentally as well. In order to reflect the experimental conditions, the liquid is a mixture of Glycerol and water and a constant viscosity is set to 200 mPa s. The ambient pressure is 11 bar and the gas velocity is 58.3 m/s, leading to a gas Reynolds number of 137 000 and a Weber number of 1375. The three-dimensional numerical domain consists of the twin-fluid nozzle and a cavity of 30 mm length and 17.4 mm diameter. The spatial resolution is 33 textmu m, which leads to 208 million of particles. The simulation is run for 45 ms of physical time using 2000 CPU. The results show that the fiber-mode breakup is well captured by the method. The shape and the dynamics of the fragmented liquid lumps are in very good qualitative agreement with the experimental observations. Further quantitative analyses are performed in terms of time average of the liquid phase, and time evolution of the spray characteristics at the exit of the cavity. Finally, due to the Lagrangian nature of the SPH method, the breakup sequence of each liquid elements can be monitored and collected. Hence, the fragmentation spectrum of this configuration is also presented.

  Smoothed Particles Hydrodynamics (SPH) simulations of the primary breakup process have been conducted using a planar prefilming airblast atomizer geometry that has been investigated experimentally. Despite the fact that a 2D study is conducted, most of the breakup phenomena are captured by the simulations. A variation of the liquid mass flow effects the simulated air flow and spray in the same way as indicated by experimental results. Using this numerical approach new insights in the primary breakup process are obtained, which can be received only difficultly in experiments. The presence of liquid at the trailing edge of the prefilmer is quantified from a side view perspective. In addition, the influence of a variation of the liquid mass flow on the liquid film and the presence of liquid at the trailing edge are characterized. Furthermore, three different wetting modes of the trailing edge are observed: The non-wetting mode which is characterized by one film wave per breakup event as well as the unstable and stable accumulation modes which are related to two film waves per breakup event. Finally, it is demonstrated that the liquid film waves and the breakup of the ligaments are slightly decoupled by the accumulation of liquid at the trailing edge.

  The second edition of this long-time bestseller provides a framework for designing and understanding sprays for a wide array of engineering applications. The text contains correlations and design tools that can be easily understood and used in relating the design of atomizers to the resulting spray behavior. Written to be accessible to readers with a modest technical background, the emphasis is on application rather than in-depth theory. Numerous examples are provided to serve as starting points for using the information in the book. Overall, this is a thoroughly updated edition that still retains the practical focus and readability of the original work by Arthur Lefebvre.

• Enhanced liquid atomization: From flow-focusing to flow-blurring. Gañán-Calvo, Alfonso M. (2005). 86(21) 214101-.

  This letter describes the generation of small turbulence scales in connection with a singular back-flow pattern leading to efficient atomization. A simple pneumatic atomizer configuration results, with a tenfold efficiency increase over available plain-jet air-blast atomizers. Back-flow atomization derives from a global bifurcation of the liquid-gas flow pattern; the bifurcation is triggered by a single geometrical parameter of the atomizer. The extremely simple geometry involved can be implemented down to the micrometric scale, thus opening the door to the improvement of current atomizers and to unprecedented designs.
