Sparse non-negative super-resolution - simplified and stabilised

We consider the problem of non-negative super-resolution, which concerns reconstructing a non-negative signal x = Sigma(k )(i=1)a(i)delta(ti) from m samples of its convolution with a window function phi(s - t), of the form y(s(j)) = Sigma(k)(i=1) a(i) phi( ...

Thermodynamic properties of the Shastry-Sutherland model from quantum Monte Carlo simulations

Frédéric Mila, Bruce Normand

We investigate the minus-sign problem that afflicts quantum Monte Carlo (QMC) simulations of frustrated quantum spin systems, focusing on spin S = 1/2, two spatial dimensions, and the extended Shastry-Sutherland model. We show that formulating the Hamilton ...

The Vanishing Hand: Efficient Market Design for Future Power Systems

Anjali Devi Vanapilli Nursimulu

Transition to low-carbon power systems is in progress, fuelled by policy-driven accelerated deployment of new renewable electricity generation technologies (wind and solar), smart electrification, prosumerisation and digitisation. Largely occurring against ...

Ergodic behaviour of "signed voter models"

Thomas Mountford, Grégory Maillard

We answer some questions raised by Gantert, Lowe and Steif (Ann. Inst. Henri Poincare Probab. Stat. 41 (2005) 767 780) concerning "signed" voter models on locally finite graphs. These are voter model like processes with the difference that the edges are co ...

Data Mapping for Unreliable Memories

Andreas Peter Burg, Georgios Karakonstantis, Christoph Studer

Future digital signal processing (DSP) systems must provide robustness on algorithm and application level to the presence of reliability issues that come along with corresponding implementations in modern semiconductor process technologies. In this paper, ...

Synthesis, electrical resistivity, thermo-electric power and magnetization of cubic ZnMnO3

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Richard Gaal, Rita Smajda, Jacim Jacimovic, Zlatko Mickovic, George Cristian Vaju

Cubic ZnMnO3 powder in the form of well-crystalline nanoflakes have been synthesized at low temperatures from a nitrate precursor. The electrical properties of cubic ZuMnO(3) samples have been established by DC resistivity (rho) and thermo-electric power ( ...

Voluntary approaches in climate policy: Comparing European and Swiss transport legislation

Alexandra Quandt

This paper investigates the effectiveness of voluntary approaches in a comparative case study on European and Swiss climate legislation. Voluntary approaches are known to be less environmentally effective and economic efficient than other climate policy in ...

Montgomery Multiplication on the Cell

Joppe Willem Bos, Marcelo Kaihara

A technique to speed up Montgomery multiplication targeted at the Synergistic Processor Elements (SPE) of the Cell Broadband Engine is proposed. The technique consists of splitting a number into four consecutive parts. These parts are placed one by one in ...

Toward Structural Dynamics: Protein Motions Viewed by Chemical Shift Modulations and Direct Detection of C ' N Multiple-Quantum Relaxation

Geoffrey Bodenhausen, Daniel Abergel

Multiple quantum relaxation in proteins reveals unexpected relationships between correlated or anti-correlated conformational backbone dynamics in alpha-helices or beta-sheets. The contributions of conformational exchange to the relaxation rates of C'N coh ...

Study of B± → D*CPK ± and DCPK± decays

Tagir Aushev, Sun Hee Kim

We report a study of the modes B± → DK ± and B± → DK± where D() decays to CP eigenstates. The data sample used contains 275 × 106 BB̄ events at the Y(4S) resonance collected by the Belle detector at the KEKB energy-asymmetric e+e- collider. The CP asymme ...
