Diffusion models in robotics: a comprehensive review

Diffusion models are a powerful class of generative models that emerge in recent years to transform Gaussian noise into samples of the target distribution through an iterative denoising process. Due to the high training stability and powerful generative capabilities, diffusion models have surpassed previous generative...

Physical Constraints in Molecular Communication: 2D Diffusion in Stiff and Crowded Hydrogels

Diffusion is a fundamental process that governs molecular transport in biological systems and is influenced by the physical and chemical properties of the surrounding environment, including matrix stiffness and molecular crowding. In this study, we developed a two-dimensional hydrogel-based model to investigate how the...

Hearing Shape from Spectrum ── Connes' Non-Commutative Geometry, Kac's Inverse Spectral Problem, and the Highway Linking Geometry and Inverse Problems ── [Paper 102]

Two lineages run through the corpus ── the geometric mainstream (Riemann → … → Hopf, Paper 91) and the integral-brain / inverse problem (reading the cause from the effect, Papers 89 and 99). This paper links the two, for the first time, by a single road. The key is the question "can shape be heard from the spectrum (th...

From trace organic contamination to three-dimensional carbonaceous deposits: a non-equilibrium redeposition mechanism under nanosecond near-infrared laser irradiation

Abstract Laser-induced contamination limits the long-term reliability of optical systems, yet the formation pathway of carbonaceous deposits under nanosecond near-infrared irradiation remains unclear.Here, tetradecane-contaminated K9 glass irradiated by a 1064-nm nanosecond laser is investigated using multiscale charac...

On identifiability limits of phase-space information in Schr\"odinger Bridges for post shell-crossing gravitational structure formation

Many nonlinear dynamical systems remain deterministic and invertible in their full state space while becoming non-identifiable after projection onto reduced observables. Gravitational shell crossing provides a canonical example: the collisionless phase-space flow remains Hamiltonian, whereas the configuration-space map...

EEG audio-tactile spatial localization task under reduced alertness

This dataset contains raw EEG data recorded at the University of Granada (CIMCYC) between March and June 2025 during an audio–tactile spatial localization task. The experiment was conducted with healthy easy-sleepers seated in a reclining armchair for approximately 2 hours and a half, with the aim of investigating mult...

MULTIPHYSICS DIGITAL TWIN OF A NONLINEAR TPMS‑GRADED BIODEGRADABLE BONE IMPLANT

A mathematical model and computational implementation of a digital twin for a bioresorbable polylactide (PLA) bone scaffold with a functionally graded triply periodic minimal surface (TPMS) architecture are developed. The model comprises four state variables (polymer mass, osteoblast population, growth factor concentra...

Under the One Word Dyeing Live an Expression with a Ceiling and One Without, Indistinguishable When Dilute ── In the site-filling kind the number of sites is a ceiling, so even at a concentration of 1000 the occupancy is 0.999500 and never exceeds one ── the separator is whether the dye's destination is a finite set of sites or a volume ── [Paper 721]

A dye entering a fibre and settling there is called dyeing. Beneath that word lie two mechanisms: one that saturates and one that takes in as much as offered. That the two diverge at high concentration and coincide at low is shown in numbers. No new theorem or law is claimed. Scope of this paper (scope note): No new th...

Mobile-Enabled Pest Prediction in Sub-Saharan Africa: An Empirical Review of SMS and Mobile Platforms Bridging Traditional Farming Knowledge and Digital Early Warning Systems

Food security in Sub-Saharan Africa is threatened by a number of agricultural pests including the fall armyworm, desert locusts and stem borers. Typical pest monitoring, mostly conducted by manual scouting and late reporting, can inhibit prompt early warning and response. This paper presents a systematic review of the...

量子)湮灭场宇宙模型:从粒子涌现到红移的累积效应解释 (Quantum)Annihilation Field Universe Model: From Particle Emergence to Cumulative Redshift

(量子)湮灭场宇宙模型:从粒子涌现到红移的累积效应解释 (Quantum)Annihilation Field Universe Model: From Particle Emergence to Cumulative Redshift Abstract This paper proposes an annihilation field universe model. The annihilation field is the core concept of this paper—a fundamental field in vacuum that forms localized ex...
