Temperature‐Modulated Threshold Response in a Volatile Memristor: Toward a Biomimetic Polymodal Nociceptive System

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an artificial polymodal nociceptor whose firing threshold is actively modulated by temperature. A volatile TiN/TiOx/ZnO/TiOx/ITO memristor shows interfacial ion–driven resistive switching and membrane‐potential‐like dynamics, enabling temperature‐dependent nociceptive behavior.

Anomalous Pressure‐Temperature Ultrahigh Sensitivities in Atomically Engineered Carbonitride MXenes for Multifunctional Wearable Human–Machine Interfaces: Joint Computational–Experimental Elucidations

open access: yesAdvanced Functional Materials, EarlyView.
Atomically engineered layered 2D Ti3CNTz carbonitride MXene exhibits ultrahigh heat and pressure sensitivity, enabling dual‐mode sensors with 300%–400% performance enhancement and durability for real‐time health‐monitoring interface devices. Precise nitrogen incorporation (e.g., Ti3C1.8N0.2Tz) boosts conductivity, enhancing temperature response, while ...

The Importance of Elections in Democratic Political Process

open access: yesПроблеми на постмодерността, 2012
There are many terms defining democracy. Some of them are very short, others are comprehensive. In practice, however, a lot of definitions are related to the political representation.

Hijackers and Hostages in Non-binding Linked-Issues Referenda: Analysis and an Application [PDF]

open access: yes
Non-binding referenda ('petitions') are an instrument of direct democracy that allows citizens to signal preferences to politicians outside the electoral cycle.

Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

Democracy, Foreign Direct Investment and Natural Resources [PDF]

open access: yes
Existing studies assume that the impact of democracy on FDI is the same for re- source exporting and non-resource exporting countries. This paper examines whether natural resources alter the relationship between FDI and democracy.

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

open access: yesAdvanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Direct Democracy at the Local Level in Poland

open access: yesПроблеми на постмодерността, 2013
Direct democracy was not known in Poland in the period before the World War II while in People’s Poland there were no proper conditions to implement it. The forms of direct democracy at the local level are village meetings, general meetings of people in ...
