Dynamic Operations in Macromolecular Data Storage

Angewandte Chemie, EarlyView.
With the exponential growth of digital data and the limitations of conventional silicon‐based storage and computing technologies, macromolecular data storage, the practice of encoding digital information within large, complex molecules like DNA or synthetic polymers, has emerged as a scalable and sustainable alternative to traditional digital ...

The Detection of Counterfeit Banknotes Using Ensemble Learning Techniques of AdaBoost and Voting

International Journal of Intelligent Engineering and Systems, 2021
The movement of cash flow transactions by either electronic channels or physically created openings for the influx of counterfeit banknotes in financial markets. Aided by global economic integration and expanding international trade, attention must be geared at robust techniques for the recognition and detection of counterfeit banknotes.

Does Banknote Quality Affect Counterfeit Detection? Experimental Evidence from Germany and the Netherlands [PDF]

SSRN Electronic Journal, 2016
Abstract Counterfeit prevention is a major concern for central banks. In search of effective policy measures, it is often claimed that a clean banknote circulation helps the general public to more easily detect counterfeits. To examine this claim, we conducted an experimental study with 250 consumers and 261 cashiers in the Netherlands ...

Supramolecular Terbium‐Threonine Chiral Emitters with Tunable Circularly Polarized Luminescence as Anticounterfeiting‐Ink for Autonomous Data Encryption

Advanced Science, EarlyView.
A one‐pot, aqueous, and scalable method for synthesizing chiral lanthanide supramolecular emitters using terbium and threonine is reported. The aqueous solution of these chiral emitters displays the following features: (i) 100 % transparency, (ii) tunable luminescence and CPL, and (iii) a pH feedback loop that controls the “on‐off” states of ...

Bio‐Derived Nanophotonic Hybrids Enabling Reconfigurable Upconversion for Multilevel Optical Encryption

Laser &Photonics Reviews, EarlyView.
A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Introduction: On the fickleness of friendship Introduction : de l'inconstance en amitié

Journal of the Royal Anthropological Institute, EarlyView.
In this Introduction to the special section, I provide a brief overview of the anthropology of friendship, particularly from the 1960s to the present, before focusing on the four articles that form the main body of the section. I argue that anthropologists who do not regard themselves as specialists in friendship will still find much to gain from ...
