Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Price-Band Stabilization Programs and Risk: An Application to the U.S. Corn Market

open access: yesJournal of Agricultural and Resource Economics, 1994
The impacts of introducing a partial price stabilization scheme in the U.S. corn market are investigated by using a modified version of the bounded price variation model.

The Impacts of U.S. Cotton Programs on the West and Central African Countries Cotton Export Earnings [PDF]

open access: yes
This study uses a stochastic simulation approach based on a partial equilibrium structural econometric model of the world fiber market to examine the effects of a removal of U.S. cotton programs on the world market. The effects on world cotton prices and

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

open access: yesAdvanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

The use of an integrated model of pest spread and commodity markets to estimate the cost of a pest outbreak [PDF]

open access: yes
There are significant benefits in integrating a biological spread model into economic assessment of the cost of pest incursions (such as varroa mite or Mexican feather grass) on agricultural industries.

Photoswitchable Conductive Metal–Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

A partial-equilibrium model of the electricity market

open access: yes, 2021
We present a model of the electricity market which has a simple connection to the rest of the economy, due to a quasi-linear utility function.A key stochastic parameter shifts electricity demand between points of time.The correlation between these demand shifts and the variation of supply from variable renewable electricity (VRE) sources is crucial for

Costly horizontal differentiation [PDF]

open access: yes
We study the effect of quadratic differentiation costs in the Hotelling model of endogenous product differentiation. The equilibrium location choices are found to depend on the magnitude of the differentiation costs (relatively to the transportation ...

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Modelling the World Wool Market: A Hybrid Approach [PDF]

open access: yes
We present a model of the world wool market that merges two modelling traditions: the partialequilibrium commodity-specific approach and the computable general-equilibrium approach.
