Topic-Graph Spherical Fusion Improves Unsupervised Legal Document Clustering
Introduces TGSF, a framework that fuses dense topic-semantic discovery with document relational graph embeddings on a joint unit hypersphere for unsupervised legal document clustering. It outperforms semantic-only, structural-only, LDA, NMF, and TF-IDF baselines on three legal benchmarks, improving NMI and ARI, and provides hyperparameter sensitivity diagnostics.

Parameter-Shared Blockwise Forecasting: Trading Sequential Compute for Storage
This study proposes Recursive Functional Decomposition (RFD), which uses a compact parameter-shared operator to sequentially emit contiguous future blocks instead of forecasting the entire horizon in one pass, trading sequential computation for parameter storage; in a frozen long-context cross-protocol comparison, it records lower test error in most cells against ten baseline families.

CasePlay: Self-Play Reinforcement Learning from Case Reports for Medical Reasoning
To address reliance on expert-labeled questions or costly synthetic data in reinforcement learning for medical LLMs, CasePlay proposes document-grounded self-play directly using unlabeled clinical case reports, with a knowledge-conditioned proposer and a rubric-judge reasoner to mitigate knowledge-point fixation and difficulty-quality mismatch, improving an SFT warm-start model by 3.1 points on average across seven medical benchmarks.

Revenue-Staff Expense Gap Widens in Public Firms, but Evidence Is Shaped by Sector and Reporting Selection
Using 7,000 firm-years for 695 public companies from 2015 to 2025, the study examines whether the gap between revenue per employee and staff expense per employee has widened, and how reporting selection and sector composition affect that inference. Its contribution is showing that the gap is concentrated in financial firms and that accounting measures cannot identify real productivity or the labor-capital split.

MENTOR Framework: Metacognition-Driven Self-Evolution for Uncovering and Mitigating Implicit Domain Risks in LLMs
The study introduces a dataset of 3,000 annotated queries across education, finance, and management, finds an average jailbreak success rate of 57.8% across 14 leading LLMs, and proposes MENTOR, a metacognition-driven self-evolution framework that reduces attack success rates via self-assessment, rule-guided inference, and a selective metacognitive evolution cycle.

SpatialScout: Evaluating VLM Agents for Active 3D Object Mapping
It introduces a benchmark for active object-level 3D mapping that requires vision-language model agents to autonomously explore indoor scenes and estimate object centers under bounded interaction budgets, filling the gap that spatial question answering cannot test metric map construction.

RSIHub: A Composable Framework for Unified Evaluation of Agent-Evolution Methods
RSIHub abstracts execution, evaluation, recovery, and lineage for agent-evolution methods into shared infrastructure, letting researchers focus on evolution policies. Its novelty lies in composing AHE, Hyperagents, A-Evolve, and GEPA via reusable recipes and comparing them under fixed model and evaluator configurations; its usefulness is reducing duplicated experimental machinery, preserving inspectable candidate histories, and tying results to evaluation conditions.

An Auditable Data-Quality Layer via Agentic Rule Discovery
Proposes an ontology-grounded, repository-native data-quality layer that treats quality rules as versioned, provenance-linked, replayable first-class artifacts, and presents a concrete implementation of its agentic rule-discovery core with a preliminary evaluation framework.

Extending DSINC beyond Heston to Non-Affine Stochastic-Volatility Models
This study generalizes the DSINC method from the affine Heston class to general one-factor stochastic-volatility models, showing that the collapse identity remains valid and providing transforms and computational schemes for the 3/2 model, SABR, and others, thereby maintaining option pricing accuracy across a broader model class.

TARSphere: A Full-Stack Framework for Long-Horizon Embodied Agents
TARSphere proposes a robot-oriented full-stack framework that runs robot policies in a physics simulator with embodied NPCs and constrained dialogue; an event-driven finite-state machine updates task states based on completed actions and delivered information. It also includes an embodied brain harness that lets a frozen multimodal large language model act through multi-level executable skills and revise decisions using observations, hierarchical memory, and execution feedbac

Heterogeneous Trading Agents Show Distinct Stress and Performance Patterns in Automated Markets
The study uses reinforcement learning to simulate three types of trading agents and finds significant differences in their market stress patterns, risk-adjusted performance, and impact on liquidity and volatility, supporting behavior-specific regulation.
