    Finance agents meet an open world: none of 150 sessions passes, and all 35 the simulated user approved fail a program check

    FinCosmos opens all three uncertainties of financial agent evaluation at once: a simulated investor reveals a hidden strategy only when asked, the agent must source its own Web data and backtest under a data cutoff, and programs verify the delivery instead of matching a reference answer. Across 150 sessions with four coding agents and a tool-free model, none is accepted, and all 35 sessions the simulated user signed off fail at least one program veto.

    Weather forecasts move to ten-minute updates: Europe's StormScope turns satellite cloud images into regional nowcasts

    NVIDIA has added StormScope EU to its Earth-2 family of open models, a regional version trained on European weather and climate data that uses EUMETSAT satellite observations to predict evolving cloud conditions across 16 Meteosat channels at 10-minute intervals. A global forecast can show a storm taking shape, but decisions about solar farms, shipping routes or insured property depend on what happens locally. At GTC Berlin, the model runs in a live pipeline with Earthmover's data platform, updating as new observations arrive and serving results as map tiles so visitors can explore European predictions without downloading whole datasets.

    Single-cell sequencing only yields snapshots: a latent cell-state model fills in gene expression at unobserved timepoints

    Single-cell RNA sequencing destroys each cell as it measures it and samples only discrete timepoints, so one cell's expression profile cannot be followed continuously. The Latent Cell-State Model approximates cell-state transitions as a Markov chain and adds a low-dimensional continuous latent variable to generate expression counts given cell state, time and gene. On the pancreatic development and Waddington-OT reprogramming datasets, maximum mean discrepancy between generated and real samples at held-out timepoints was 0.011 and 0.006 (pancreatic days 3 and 6) and 0.030 and 0.018 (reprogramming days 3.5 and 4), lower than the three compared methods.

    Video LLMs stop comparing every token: codec motion and residuals cut matching by two-thirds

    Compressing visual tokens for video large language models costs feature comparisons in the compression decisions themselves. This method aligns reference-frame dependencies, motion vectors and residuals already present in compressed video to the visual token grid, uses them to propose small candidate sets, then verifies with local visual similarity. Across three video LLMs and four video-understanding benchmarks, performance matches the training-free baseline FlashVID and sometimes exceeds it, while comparisons for token protection and temporal matching drop substantially.

    OncoNoteBERT trains oncology-specific encoders on 290,000 UK outpatient notes: continued pretraining cuts perplexity to 2.10, while a from-scratch tokenizer shortens sequences by about 23.6%

    Using 290,026 outpatient oncology notes from 21,564 patients treated for lung and head-and-neck cancer at a UK specialist oncology centre, the study compared RadBERT and PathologyBERT with two local strategies: OncoNote-RadBERT, produced by continued masked language model pretraining, reached a validation perplexity of 2.10, while OncoNoteBERT, trained from scratch with an oncology-specific WordPiece tokenizer, reached 2.83 but the most efficient tokenisation (subword fertility 1.224, normalised sequence length 0.7636, about 23.6% fewer tokens) and returned clinically acceptable predictions for 12 of 13 masked-token probes versus 7 of 13 for OncoNote-RadBERT; both local models represented the institutional placeholder [REMOVED] as a single learnable token.

    AutoDataBench scores Kimi-3 highest at 60.68 overall, yet the retrieval leader on in-distribution data ranks last out of distribution

    The work introduces AutoDataBench, a controlled testbed that isolates data intelligence under fixed training pipelines and resource budgets across tool-use data diagnosis and repair, retrieval data organization, and knowledge injection, evaluates seven frontier LLMs on iterative data decisions, finds that agent-curated data approaches expert references on tool use and retrieval while strong in-distribution scores do not guarantee out-of-distribution transfer, and shows that reusing optimization trajectories as mid-training data improves downstream coding performance.

    DN-MOPD normalizes per-domain teacher feedback and lifts the six-task average over MOPD from 58.4/50.3/26.6 to 59.6/52.5/29.0 across three Qwen3.5 sizes

    The work finds that multi-teacher on-policy distillation (MOPD) with domain-label routing alone fails to beat the strongest single-teacher student and transfers little of the mathematics expert's gain, because domain feedback is unbalanced (in the first training batch instruction-following log-ratios are 2.3-4.4 times as dispersed as the pooled signal while mathematics is about half as dispersed, and for the initial 4B student the instruction-following loss supplies 94% of the combined gradient), and proposes DN-MOPD, which keeps label routing and rescales each domain's distillation advantages by the clipped ratio of pooled to domain log-ratio spread estimated every batch, improving the six-task average over MOPD at every size and both evaluation budgets (1.17-2.36 points at 16K, 2.47-3.

    Frozen DINOv3 features injected into a 3D U-Net via Room-Lite mixing and calibrated fusion reach Dice 0.758 for 3DRA aneurysm segmentation and remove all cross-dataset failures

    The work proposes DINO-3DRA, a dual-path framework that injects frozen 2D vision foundation model DINOv3-Small features into a trainable 3D U-Net backbone through Room-Lite spatial mixing and calibrated residual fusion, achieving state-of-the-art aneurysm segmentation on multi-centre 3D rotational angiography (3DRA) @neurIST data (233 patients, four institutions) with Dice 0.758, HD95 2.75 mm and a 13% gain over nnU-Net using only 5.72M trainable parameters; ablations attribute the gains to structured cross-dimensional transfer rather than loss design, and without fine-tuning on CADA (n=45) and SHINY-ICARUS (n=30) it reduces Dice<0.5 failures from 11.1% and 3.3% to 0%.

  9. The entanglement of place in the corporatised governance of schools: Thinking poetically with Barad

    Drawing on Karen Barad's (2007) concepts of intra-action and the agential cut, this chapter employs a poetic inquiry approach situated in three multi-academy trusts in England, and through two agential cuts embodied in distinct poetic forms materialises how place entangles with governance policy, architecture, and actors to configure parental engagement, thereby repositioning place as a co-agentic participant in governance.

    Comprehensive Reconstruction of Collider Events with Hypergraph Representation Learning and Graph-Conditioned Diffusion

    The work presents VyPER, a geometric learning framework that represents collider events as hypergraphs with a physics-inspired topology, combining supervised classification of hyperedges for assigning measured jets and charged leptons to parent particles with a diffusion model for predicting unmeasured neutrino kinematics, optimized jointly through a joint loss function within a unified framework, and compares its performance to existing analytical and machine-learning-based reconstruction techniques across several proton-proton collision processes, indicating that accurate event reconstruction is achievable across a diverse range of Standard Model physics processes.
