Local vs. cooperative: Unraveling glass transition mechanisms with SEER

Which phenomenon slows down the dynamics in supercooled liquids and turns them into glasses is a long-standing question of condensed matter. Most popular theories posit that as the temperature decreases, many events must occur in a coordinated fashion on a ...

No money, no honey? Financial versus knowledge and demand constraints on innovation

Gabriele Pellegrino

The paper adds to the literature on the barriers to innovation in two ways. First, we assess comparatively what mostly constrains firms' ability to translate investment in innovation activity into new products and processes, whether it is mainly finance, a ...

Active Guard Ring Characterization for Smart Power ICs

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

This paper shows SPICE simulation results of active guard ring structures which are typically employed in Smart Power ICs. Active guard rings act as barriers limiting the flow of minority carriers injected into the substrate toward sensitive circuits. The ...

Exploring barriers to climate change adaptation in the Swiss tourism sector

Philippe Thalmann, Cecilia Matasci

Increasingly, various sectors are affected by climate change and need to find ways to adapt with much public guidance and support. This paper examines the adaptation process of a sector that started it some time ago - Swiss Alpine tourism. It identifies ba ...

Trade policy: Home market effect versus terms-of-trade externality

Chiara Forlati

We study trade policy in a two-sector Krugman (1980) trade model, allowing for wage, import and export subsidies/taxes. We study non-cooperative trade policies, first for each individual instrument and then for the situation where all instruments can be se ...

Global and local gyrokinetic simulations of high-performance discharges in view of ITER

Olivier Sauter, Laurent Villard, Stephan Brunner

One of the key challenges for plasma theory and simulation in view of ITER is to enhance the understanding and predictive capability concerning high-performance discharges. This involves, in particular, questions about high-beta operation, ion temperature ...

Achieving and sustaining advanced scenarios in ITER modelled by CRONOS and DINA-CH

Jonathan Bryan Lister, Javier García Hernández, Karim Besseghir

The heating and current drive characteristics for accessing advanced scenarios in ITER, close to those obtained in present-day experiments, are analysed together with the plasma performance using the prescribed-boundary CRONOS suites of codes. For the hybr ...

'Technology, innovation and knowledge: An Asian perspective': Introduction

Christopher Tucci

Technology, knowledge and innovation play a crucial role in explaining the competitive potential of firms and countries in today’s globalised world. With lowered barriers to international activities, firms develop technological competencies abroad, either ...

Public Urban Transport, Mobility Patterns and Social Exclusion : The Case of Santiago de Chile

Regina Witter

What are the social impacts of a new, less efficient public transport system in a city that is known for its inequality concerning access to daily activities and participation in urban life? More precisely, what are the implications of a re-regulated trans ...

Light engineering of the polariton landscape in semiconductor microcavities

Romuald Houdré, Cristiano Ciuti

We demonstrate a method to create potential barriers with polarized light beams for polaritons in semiconductor microcavities. The form of the barriers is engineered via the real space shape of a focalized beam on the sample. Their height can be determined ...

Barriers and Needs for Building Integration of Solar Thermal and Photovoltaics

Maria Cristina Munari Probst

The International Energy Agency (IEA) Task 41 is conducting an international survey concerning the integration of solar energy systems and architecture in order to identify barriers that architects are facing in incorporating active solar technologies in t ...

A model for the design of effective and resilient supply chain security management systems

Ximena Gutiérrez Rueda

The current business environment has become more risky and variable. In particular, the recent terrorist attacks against western economies have revealed the vulnerability of global supply chains. These events showed that companies that move cargo internati ...

The role of the radial electric field for the transition to high confinement regimes

Duccio Testa

The radial electric field E-r(x, t), and particularly its gradient, has been invoked by various theories and empirical models as a crucial parameter 'per se' for determining the transition to high confinement regimes, such as the onset of an internal trans ...

Inductive current density perturbations to probe electron internal transport barriers in tokamaks

Olivier Sauter, Stefano Coda, Timothy Goodman, Roland Behn, Alberto Bottino, Emiliano Fable, Costanza Zucca, Andrei Martynov, Petri Nikkola

Improved electron energy confinement in tokamak plasmas, related to internal transport barriers, has been linked to nonmonotonic current density profiles. This is difficult to prove experimentally since usually the current profiles evolve continuously and ...
