Polynomial-time universality and limitations of deep learning

The goal of this paper is to characterize function distributions that general neural networks trained by descent algorithms (GD/SGD), can or cannot learn in polytime. The results are: (1) The paradigm of general neural networks trained by SGD is poly-time ...

alpha-Diimine homologues of cisplatin: synthesis, speciation in DMSO/water and cytotoxicity

Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Schoch

The Pt(ii) -diimine complexes [PtCl2{N-2-(HCNR)(2)}] (R = C6H11, 1; 4-C6H10OH, 2; 4-C6H4CH3, 3; 4-C6H4OH, 4) and [PtCl2{N-2-(CH3CNOH)(2)}] (5) were prepared in 60-81% yields from the 1:1 molar reactions of cis-[PtCl2(DMSO)(2)] with the appropriate -diimine ...

Assessing the Effect of Calcite Impurities in Clay on Optimal Dehydroxylation Parameters for Enhanced Reactivity

Karen Scrivener, Franco Alberto Zunino Sommariva

This study focused on understanding the influence of different amounts of calcite impurities (0 to 10% by mass) on the optimal parameters for clay dehydroxylation and the reactivity of the final calcined clay. A surface response experimental design was use ...

Partial Molar Volumes of Aqua Ions from First Principles

Alfredo Pasquarello, Julia Anna Wiktor

Partial molar volumes of ions in water solution are calculated through pressures obtained from ab initio molecular dynamics simulations. The correct definition of pressure in charged systems subject to periodic boundary conditions requires access to the va ...

Designing Statistical Estimators That Balance Sample Size, Risk, and Computational Cost

Volkan Cevher

This paper proposes a tradeoff between computational time, sample complexity, and statistical accuracy that applies to statistical estimators based on convex optimization. When we have a large amount of data, we can exploit excess samples to decrease stati ...

Preparation and Mechanism of Cu-Decorated TiO2-ZrO2 Films Showing Accelerated Bacterial Inactivation

César Pulgarin, Rosendo Sanjines, Juan Kiwi, Sami Rtimi

Antibacterial robust, uniform TiO2-ZrO2 films on polyester (PES) under low intensity sunlight irradiation made up by equal amounts of TiO2 and ZrO2 exhibited a much higher bacterial inactivation kinetics compared to pure TiO2 or ZrO2. The TiO2-ZrO2 matrix ...

Graphene : from Growth to Devices

Laurent Syavoch Bernard

We report a full study of graphene synthesis by CVD on Cu surface. Two CVD methods have been developed. The first is a static one, which yields monolayer of graphene at low pressure of methane in 3 minutes at 1000 C. The second one is an equimolar method w ...

Influence of visco-elasticity on the stress development induced by alkali-silica reaction

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

The alkali-silica reaction causes long-term degradation in the microstructure of affected concrete as well as macroscopic expansion. In this paper, a micro-mechanical model based upon an explicit representation of the microstructure has been used to simula ...
