Guiding Diffusion with Logical Constraints: Molecular Graph Generation Under Lipinski’s Rules

Surface Diffusion–Driven Adsorption of Pyrene on Al- MCM-41: An Integrated Experimental and Phenomenological Modeling Study

Vacancy diffusion in transition metal diborides using diverse machine-learning potentials

Overall, nanosecond-scale finite-temperature simulations demonstrate the reliability and practical applicability of MLIPs for studying diffusion phenomena in complex ceramic materials.

A risk-aware multimodal temporal reinforcement learning approach for collision avoidance of unmanned surface vehicles in multi-dynamic-obstacle scenarios

This study addresses autonomous collision avoidance for unmanned surface vehicles in multi-dynamic-obstacle maritime scenarios, where the number of obstacles varies, risk interactions are complex, and dynamic environmental evolution is difficult to exploit effectively. A Risk-Aware Multimodal Temporal Proximal Policy O...

The Impact of Artificial Intelligence on the Generative Design and Cross-Domain Performance of Athletic Footwear

The athletic footwear industry is shifting from conventional linear R&D pipelines to advanced digital workflows driven by artificial intelligence (AI). This paper evaluates how AI-driven tools optimize established manufacturing paradigms, focusing on the s ystemic transition within sports shoe development rather than i...

A knowledge-augmented diffusion framework for generating regionally distinctive architectural facades: a case study of Huizhou dwellings

Generating heritage facade images with recognizable regional style is increasingly feasible with diffusion models, but prompt engineering or standard fine-tuning alone rarely encodes the construction logic, spatial hierarchy, and symbolic rules that make such heritage architecture intelligible. This gap is critical for...

GroupKV: Hierarchical KV Cache Management for Long-Context Diffusion LLM Inference

Diffusion large language models (dLLMs) are emerging as a promising generative paradigm that complements autoregressive decoding. In long-context settings, KV cache bloat and offloading transfer overhead have become primary bottlenecks in inference systems. Meanwhile, the periodic full-sequence recomputation and locali...

Physical Compilation for Multimaterial Fabrication: Architecture, Feasibility Bounds, and Verification

VLWNC-IF-VF investigates a physically grounded architecture for a broadly capable “light printer in a box.” The proposed system combines optical addressing, chemistry-specific processing cartridges, accessible reactive surfaces, hierarchical assembly, and integrated metrology. Its guiding workflow is: describe matter →...

Whether Being Advantageous Matters Is Decided by the Size of the Population ── A mutation with a selection coefficient of 0.01 fixes 19.8013 times as often as a neutral one at N=500, but only 1.2012 times as often at N=10 ── what decides is not s but Ns ── and at s=0 the probability is exactly the neutral value ── [Paper 478]

An advantageous mutation is said to spread. This paper shows that what decides whether the advantage matters is not its size but its product with the population size──where Ns is small, being advantageous does no good. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed─...

What the Waiting Is For Is Diffusion, Not Reaction ── One millimetre takes 2.7778 hours and a hundred takes 3.17 years ── ten times the distance costs 100 times the time ── and ten kelvin multiplies the reaction by 4.0553 while multiplying the diffusion by only 1.5220 ── [Paper 445]

Ageing is taken to be slow because the reaction is slow. This paper shows that sometimes what one waits for is transport──and that transport barely speeds up when heated. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──the diffusion equation, the square law for diff...
