CINEMO-NET: implicit neural and diffusion-based joint demosaicking and denoising

Demosaicking and denoising of Colour Filter Array (CFA) images are challenging due to incomplete spectral sampling, sensor noise, zipper artefacts, and high-frequency detail loss. To address these limitations, this paper proposes a novel CFA-aware Implicit Neural Representation Diffusion-Integrated Memory Optimization...

Comment on jecats-2026-12

Abstract. Condensation trails (contrails) evolve from formation and rapid growth to dissipation or transition into cirrus clouds (i.e., the long-term diffusion regime), where the latter phase largely determines their radiative forcing. This research develops a high-speed Eulerian contrail plume solver for large-scale a...

It is time to revisit the external determinants of state terror

Authoritarian regimes are frequently influenced by external policies and transnational relationships when shaping domestic repression strategies. Existing empirical research has largely focused on demonstration and diffusion effects, emphasizing how governments emulate repressive practices observed abroad. Similarly, r...

Personalized Electrocardiographic and HRV Dynamics for Acute Stress Detection: A Leave-One-Subject-Out Benchmark on WESAD

Automated classification of acute psychological stress from non-invasive wearable electrocardiography (ECG) is a fundamental problem in physiological computing, affective state recognition, and wearable Internet of Medical Things (IoMT). A central barrier to cross-subject generalization is inter-individual baseline het...

Mechanics of electroadhesion by polycation interfacial bridging: sticky electrophoresis, ionic complexation and chain entanglement

Abstract An e-GLUE is a polymer network containing interpenetrating polycations, which can bond the anionic network of mucosa by polycation interfacial bridging under an electric field. This paper formulates a theoretical model to study such electroadhesion by electrophoresis of polycations, ionic complexation between...

Tricking Turing: How to Build a Geometric Checkerboard on Living Tissue

The snake’s head fritillary (Fritillaria meleagris) displays one of the rarest pigmentation motifs in the plant kingdom: a high-contrast checkerboard of alternating purple and white domains on its flowers. Standard reaction–diffusion theory does not generically produce this pattern: while Turing instabilities in isotro...

Tricking Turing: How to Build a Geometric Checkerboard on Living Tissue [Simulation Code]

Simulation code for FASHION (Feedback-driven Anisotropic Self-organized Heterogeneity In Oriented Networks), a three-phase biophysical model explaining the violet/white checkerboard pattern of the snake's head fritillary (Fritillaria meleagris). The model combines a Turing reaction-diffusion process (Gray-Scott) spatia...

Unsupervised Brain Anomaly Detection as a Bayesian Inverse Problem with Diffusion Prior

This work introduces a latent spatial anomaly mask that models pixel-wise consistency between a test image and its latent corresponding pseudo-healthy image, and proposes an approximation of the unknown generation process that links healthy anatomy, anomalies, and the observed image, enabling a well-defined likelihood...

A novel tailing curve simulation model for sequential transmission in multiproduct pipeline based on fractional order integral algorithm

Abstract Accurate prediction of intermixing‐zone tailing is essential for interface cutting and quality control during the sequential transportation of refined petroleum products. This study develops a time‐fractional convection‐diffusion (TFCD) model that incorporates transport‐history effects to reproduce asymmetric...

Isolation, identification, and whole-genome sequencing analysis of a serotype D Pasteurella multocida strain from sheep in Xinjiang, China

Abstract Purpose Pneumonia resulting from the co-infection of Pasteurella multocida (Pm) with Mannheimia haemolytica and Mycoplasma pneumoniae is a primary cause of mortality in sheep. Specifically, serotypes A and D of Pm induce enzootic pneumonia, causing substantial economic losses. This study aims to investigate th...
