A Generic Framework for Adaptive Vague Logics

open access: yes, 2006
A generic format for adaptive vague logics is presented. The concrete adaptive vague logics based on this format are able to (1) identify sentences as vague or non-vague in the context of a given set of premisses, and to (2) dynamically adjust the ...

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media

open access: yesAdvanced Materials Technologies, EarlyView.
Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Normal Spaces on Vague Sets

open access: yesInternational Journal of Innovative Science and Research Technology
The concept of vague sets provides an effective mathematical framework for representing uncertainty by considering both the evidence supporting and opposing the membership of an element. Integrating vague set theory with topology leads to the development of vague topological spaces, which generalize classical topological concepts under uncertain ...

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Microwall‐Integrated Terahertz Metasurfaces for Spatially Guided Label‐Free Sensing of Micrometer‐Scale Plastic Particles

open access: yesAdvanced Materials Technologies, EarlyView.
A THz metasurface device integrating a metal–dielectric–metal resonator with microwall‐defined recessed regions enables spatially guided, label‐free sensing of micrometer‐scale plastic particles. The as‐fabricated devices exhibit distinct THz reflection resonances for 3.1‐µm polystyrene particles and a concentration‐dependent resonance‐frequency‐shift ...

Transparent Single‐Dye NIR Photonic Platform for Multimodal Optical Authentication

open access: yesAdvanced Optical Materials, EarlyView.
A single‐component DHP‐SQ dye integrates visible transparency, near‐infrared (NIR) fluorescence, and photothermal functionality into one molecular platform. NIR‐selective visualization transforms visually imperceptible printed patterns into readily authenticated information, while screen‐printing compatibility enables well‐defined patterning on diverse

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

open access: yesAdvanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...
