Bioactive Gold Plasmonic Interfaces Meet Artificial Intelligence: Advancing Saliva‐Based Surface‐Enhanced Raman Spectroscopy Diagnostics

open access: yesSmall, EarlyView.
ABSTRACT Bioactive gold plasmonic nanostructures are enabling non‐invasive saliva diagnostics by amplifying weak Raman signals and converting complex biofluid chemistry into information‐rich spectral fingerprints. This Review examines saliva‐based Raman and surface‐enhanced Raman spectroscopy (SERS) integrated with artificial intelligence (AI) from a ...

A Test of the Coase Conjecture Using Prices of Electronic Books

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

Toward an Intermediate Structural Representation of Organization in Complex Systems

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Organization is widely recognized as a fundamental concept in complex systems science, yet it rarely appears as an explicit object of scientific representation. Existing approaches successfully represent components, interactions, mechanisms, dynamical states, networks, or functions, but organizational properties are generally inferred from ...

A Multi‐Sequence Adversarial Fusion U‐Net for Brain Tumor Image Segmentation

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
In the field of brain tumor image segmentation, in order to avoid the impact of insufficient number of training samples, the method of fusing multi‐modal MRI information before segmentation is widely used. However, when fusing different modal features, existing methods only add fixed weights to the features of each modality, resulting in insufficient ...

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

open access: yesVIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...
