Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

Advanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Exploring the Role of Artificial Intelligence in Precision Photonics: A Case Study on Deep Neural Network‐Based fs Laser Pulsed Parameter Estimation for MoOx Formation

Advanced Photonics Research, EarlyView.
Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

Microwave Monitoring by Compact Carbon Nanotube Photo‐Thermoelectric Sensors Beyond the Diffraction Limit Toward Ultrabroadband Non‐Destructive Inspections

Advanced Sensor Research, EarlyView.
This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...

Information Hiding, Inheritance and Concurrency

, 2005
We aim to provide information hiding support in concurrent object-oriented programming languages. We study the issue of information hiding at the object level and class level, in the context of an object-oriented extension of the Join calculus a process calculus in the tradition of the Pi-calculus.
