Topological Properties of International Commodity Market: How Uncertainty Affects the Linkages?
Agribusiness, EarlyView.ABSTRACT The study aims to explore the network topology of the international commodity market by examining the interconnections among 21 commodity futures across various categories, including energy, precious and industrial metals, and agriculture. We analyze the market structure of these commodity futures under both low and high uncertainty conditions

Haptic In‐Sensor Computing Device Based on CNT/PDMS Nanocomposite Physical Reservoir
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.Using a porous carbon nanotube‐polydimethylsiloxane nanocomposite, a sensor array integrated with a physical reservoir computing paradigm capable of in‐sensor computing is demonstrated. The device is able to classify between nine objects with an accuracy above 80%, opening the possibility for low‐power sensing/computing for future robotics.

Ag/Ag2S Nanoparticle‐Based In‐Materio Lightweight Cryptographic System for IoT Edge Security
Advanced Intelligent Systems, EarlyView.This work presents a nanomaterial‐based in materio encryption method that directly transforms analog signals through nonlinear Ag/Ag2S nanoparticle networks. By exploiting the inherently nonuniform characteristics that arise from random arrangement of nanoparticles as a unique security key, the approach produces highly complex encrypted waveforms ...

The Range of the Garefowl (Alca impennis) [PDF]
Nature, 1898 IN 1856 the late Dr. Gray obtained for the British Museum an example of this extinct species from the collection of the late Prof. van Lidth de Jeude of Utrecht, and for some reason unknown to me had the locality “Labrador” painted on its stand. As I had been informed with certainty by the late Prof. J. T.

Chemistry – A European Journal, EarlyView.Monolayer TNS cover Au/SiO2 and Au/CeO2 surfaces, forming Au–TiOx contact structure that serve as active sites for CO oxidation, thereby significantly improving catalytic activity. On Au/SiO2, the Au–TiOx interface was generated through TNS adsorption and calcination, while TNS adsorption solely promoted the Au–TiOx interface formation on Au/CeO2.
