Making more of middles: advancing the middle-out perspective in energy system transformation

Social and technological innovations are commonly seen as either being induced from the ‘top-down’ – e.g., by policymakers – or evolving from the ‘bottom-up’ – e.g., by consumers. Instead, a ‘middle-out’ perspective (MOP) focuses on agents of change that are located in the middle, between the top and the bottom. Janda and Parag (2013) and Parag & Janda (2014) describe how middle actors include

Sustainability as a Real Utopia – heuristics for emancipatory sustainability research

The idea of ‘sustainability as a real utopia’ elaborated on here builds on sociologist Erik Olin Wright’s emancipatory social science and is a heuristic for interdisciplinary research on emancipatory alternatives that move society towards achieving sustainability. Starting from the proposition that socially relevant environmental problems are rooted in how social structures and institutions intera

Test Flow Selection for Stacked Integrated Circuits

Integrated circuits (ICs) with a single chip (die) are typically tested with a test flow consisting of two test instances: (1) wafer sort for the bare chip and (2) package test for the packaged IC. For ICs with stacked chips - 3D Stacked ICs - there are many possible test instances, even more test flows, and no commonly used test flow. In this paper, we propose a test flow selection algorithm (TFS

Is China's outward investment in oil a global security concern?

The motivations prompting China's dramatic increase in outward foreign direct investment (OFDI) are not always clear, especially regarding OFDI by state-owned enterprises (SOEs) in energy and natural resources. First, both commercial and governmental interests are intertwined, although not necessarily in lock-step. Chinese SOEs listed in the West may worry about the reputational risks to their glo

New Technique for Preconditioning of the Spinal Cord Before Endovascular Repair of Descending Thoracic and Thoracoabdominal Aortic Aneurysms

Purpose: To propose a new simplified technique to occlude multiple segmental arteries for staging and preconditioning of the spinal cord to decrease the potential for spinal cord ischemia after thoracic and thoracoabdominal aortic aneurysm repair. Technique: A thoracic stent-graft that flares out to a maximum of 51 mm is deployed in a standard fashion covering all segmental arteries where graft-wa

Ab initio optical potentials and nucleon scattering on medium mass nuclei

We show first results for the elastic scattering of neutrons off oxygen and calcium isotopes obtained from ab initio optical potentials. The potential is derived using self-consistent Green's function theory (SCGF) with the saturating chiral interaction NNLOsat. Calculations are compared to available scattering data and show that it is possible to reproduce low energy scattering observables in med

From bare to renormalized order parameter in gauge space : Structure and reactions

It is not physically obvious why one can calculate with similar accuracy, as compared to the experimental data, the absolute cross section associated with two-nucleon transfer processes between members of pairing rotational bands, making use of simple BCS (constant matrix elements) or of many-body [Nambu-Gorkov (NG), nuclear field theory (NFT)] spectroscopic amplitudes. Restoration of spontaneous

Ab initio optical potentials and nucleon scattering on medium mass nuclei

We show the first results for the elastic scattering of neutrons off oxygen and calcium isotopes obtained from ab initio optical potentials. The potential is derived using self-consistent Green's function theory (SCGF) with the saturating chiral interaction NNLOsat. Our calculations are compared to available scattering data and show that it is possible to reproduce low-energy scattering observable

Landau parameters for energy density functionals generated by local finite-range pseudopotentials

In Landau theory of Fermi liquids, the particle-hole interaction near the Fermi energy in different spin-isospin channels is probed in terms of an expansion over the Legendre polynomials. This provides a useful and efficient way to constrain properties of nuclear energy density functionals in symmetric nuclear matter and finite nuclei. In this study, we present general expressions for Landau param

Nonlocal energy density functionals for pairing and beyond-mean-field calculations

We propose to use two-body regularized finite-range pseudopotential to generate nuclear energy density functional (EDF) in both particle-hole and particle-particle channels, which makes it free from self-interaction and self-pairing, and also free from singularities when used beyond mean field. We derive a sequence of pseudopotentials regularized up to next-to-leading order and next-to-next-to-lea
