Tensor-Based Numerical Method For Stochastic Homogenization

Quentin Olivier Martin Ayoul--Guilmard

This paper addresses the complexity reduction of stochastic homogenization of a class of random materials for a stationary diffusion equation. A cost-efficient approximation of the correctors is obtained using a method designed to exploit quasi-periodicity ...

Efficient lattice Green's function method for bounded domain problems

William Curtin, Max Ludwig Hodapp, Ankit Gupta

The lattice Green's function method (LGFM) is the discrete counterpart of the continuum boundary element method and is a natural approach for solving intrinsically discrete solid mechanics problems that arise in atomistic-continuum coupling methods. Here, ...

Gene expression patterns associated with multidrug therapy in multibacillary leprosy

Stewart Cole, Andrej Benjak, Charlotte Avanzi, Philippe Busso

Multidrug therapy (MDT) has been successfully used in the treatment of leprosy. However, although patients are cured after the completion of MDT, leprosy reactions, permanent disability, and occasional relapse/reinfection are frequently observed in patient ...

Perceptual Quality of Point Clouds with application to Compression

Evangelos Alexiou

Modern information technologies and human-centric communication systems employ advanced content representations for richer portrayals of the real world. The newly adopted imaging modalities offer additional information cues and permit the depiction of real ...

Fast Block Sequential Decoding of Polar Codes

Kirill Ivanov

A reduced complexity sequential decoding algorithm for polar (sub) codes is described. The proposed approach relies on a decomposition of the polar (sub) code being decoded into a number of outer codes, and on-demand construction of codewords of these code ...

Improved decoding of second-order Reed-Muller codes

Rüdiger Urbanke, Kirill Ivanov

In this paper, we consider low-complexity decoding of second-order Reed-Muller codes. A class of polynomial-time algorithms, based on the projections onto first-order codes, is studied. An old representative of this class, originally developed for binary s ...

Recompression Of Hadamard Products Of Tensors In Tucker Format

Daniel Kressner

The Hadamard product features prominently in tensor-based algorithms in scientific computing and data analysis. Due to its tendency to significantly increase ranks, the Hadamard product can represent a major computational obstacle in algorithms based on lo ...

Improved hardness results for unique shortest vector problem

Divesh Aggarwal

The unique shortest vector problem on a rational lattice is the problem of finding the shortest non-zero vector under the promise that it is unique (up to multiplication by -1). We give several incremental improvements on the known hardness of the unique s ...

NAD(+) repletion improves muscle function in muscular dystrophy and counters global PARylation

Johan Auwerx, Carlos Canto Alvarez, Laurent Mouchiroud, Dongryeol Ryu, Hongbo Zhang, Vincenzo Sorrentino, Keir Joe Menzies, Xu Wang, Karim Laurent Gariani

Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to ...

Aqueous Titanium Trichloride Promoted Reductive Cyclization of o-Nitrostyrenes to Indoles: Development and Application to the Synthesis of Rizatriptan and Aspidospermidine

Jieping Zhu, Qian Wang, Shuo Tong, Zhengren Xu, Mathias Mamboury

Treatment of o-nitrostyrenes with aqueous TiCl3 solution at room temperature afforded indoles via a formal reductive C(sp2)-H amination process. A range of functions such as halides (Cl, Br), carbonyl (ester, carbamate), cyano, hydroxyl and amino groups we ...

Learning decision rules for energy efficient building control

Colin Neil Jones

While rule based control (RBC) is current practice in most building automation systems that issue discrete control signals, recent simulation studies suggest that advanced, optimization based control methods such as hybrid model predictive control (HMPC) c ...

Computational Reduction for Parametrized PDEs: Strategies and Applications

Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni

In this paper we present a compact review on the mostly used techniques for computational reduction in numerical approximation of partial differential equations. We highlight the common features of these techniques and provide a detailed presentation of th ...

Learning Near-optimal Decision Rules for Energy Efficient Building Control

Colin Neil Jones

Recent studies suggest that advanced optimization based control methods such as model predictive control (MPC) can increase energy efficiency of buildings. However, adoption of these methods by industry is still slow, as building operators are used to work ...

Multi-Graph Sampling Of Online Communities Via Mean Hitting Time

We derive a framework for sampling online communities based on the mean hitting time of its members, considering that there are multiple graphs associated with the same vertex set V representing the social network. First, we formulate random walk models on ...

Gold catalysis at the gas-solid interface: role of the support in determining activity and selectivity in the hydrogenation of m-dinitrobenzene

The catalytic gas phase hydrogenation of m-dinitrobenzene (1 atm, 423 K) over laboratory synthesised (1 mol%) Au supported on Al2O3, TiO2, Fe2O3 and CeO2 and a reference Au/TiO2 (World Gold Council) has been investigated. The catalysts were prepared by dep ...

Reduction of stochastic parity to stochastic mean-payoff games

A stochastic graph game is played by two players on a game graph with probabilistic transitions. We consider stochastic graph games with w-regular winning conditions specified as parity objectives, and mean-payoff (or limit-average) objectives. These games ...

GDNF-secreting human neural progenitor cells increase tyrosine hydroxylase and VMAT2 expression in MPTP-treated cynomolgus monkeys

Patrick Aebischer

Human neural progenitor cells (hNPCs) have been proposed as a potential source of cells for ex vivo gene therapy. In this pilot study, three 5-year-old female cynomolgus monkeys received a single intracarotid infusion of MPTP, followed 1 week later by MRI- ...

Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?

Alfred Johny Wüest, Beat Mueller

Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient loading and installing aeration/oxygenation systems. For five eutrophic lakes, three of which have been artificially oxygenated and aerated for alm ...
