The World of Wars: Risky Systems – A second-order observation of future wars

Nordicum-Mediterraneum, 2014
The world of the future will not be one without wars. The many hopes we have about a future peace governed by a more or less confederal state will not make wars obsolete.

Who Is Eating the Outflow?: High-Angular Resolution Study of an Intermediate-Mass Protostar in L1206

, 2006
Up to now only a few intermediate-mass molecular outflows have been studied with enough high-angular resolution. The aim of this work is to study in detail the intermediate-mass YSO IRAS 22272+6358A, which is embedded in L1206, and its molecular outflow,

High‐Yield Fabrication of Electrolyte‐Gated Transistors Based on Graphene Acetic Acid

Advanced Electronic Materials, EarlyView.
We fabricated a liquid‐gated transistor based on graphene acetic acid, which is dielectrophoretically deposited, featuring a spatial resolution down to 10 microns. Our method enables a versatile and reproducible fabrication featuring state‐of‐the‐art performance.

From unipolarity to bipolarity: Systemic transformation and the emergence of post-unipolar international politics [PDF]

Journal of Regional Security
With the decline of U.S. unipolarity and the rise of Sino-American bipolarity, this article explores a conceptualization of systemic transformation in international politics and its implications for outcomes in state behaviors during the transition ...

Photoresponse Properties of Ambipolar Transport in WSe2 Field‐Effect Transistors

Advanced Electronic Materials, EarlyView.
This study explores the photoresponse of WSe2 ambipolar field‐effect transistors, which exhibit unipolar, saturation, and ambipolar transport regions. Light illumination induces a shift of critical voltage with enhanced photocurrent generation driven by the photogating effect without the material degradation seen in avalanche photodetectors. This study

All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture

Advanced Electronic Materials, EarlyView.
Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

Indian Involvement in Afghanistan: Stepping Stone or Stumbling Block to Regional Hegemony? [PDF]

This paper seeks an explanation for the resilience of the Syrian authoritarian regime under Hafez and Bashar Al-Asad. It will be argued that this resilience is to a relevant extent caused by the fact that the regime’s “material” as well as “ideational ...

Model‐Based Time‐Modulated Write Algorithm for 1R Analog Memristive Crossbar Arrays

Advanced Electronic Materials, EarlyView.
A novel model‐based time‐modulated write algorithm efficiently programs analog 1R memristive crossbar arrays by varying pulse duration at a fixed voltage. By leveraging a physics‐based compact model and a dynamic gain mechanism, this approach overcomes device nonlinearities and parasitic effects.
