Positive scalar curvature and the Euler class | We prove the following generalization of the classical Lichnerowicz vanishing
theorem: if $F$ is an oriented flat vector bundle over a closed spin manifold
$M$ such that $TM$ carries a metric of positive scalar curvature, then
$<\widehat A(TM)e(F),[M]>=0$, where $e(F)$ is the Euler class of $F$.

Online Service with Delay | In this paper, we introduce the online service with delay problem. In this
problem, there are $n$ points in a metric space that issue service requests
over time, and a server that serves these requests. The goal is to minimize the
sum of distance traveled by the server and the total delay in serving the
requests. Thi... | 1 | 0 | 0 | 0 | 0 | 0 |
Comparison of dynamic mechanical properties of non-superheated and superheated A357 alloys | The influence of superheat treatment on the microstructure and dynamic
mechanical properties of A357 alloys has been investigated. The study of

by the dynamic mecha... | 0 | 1 | 0 | 0 | 0 | 0 |
On the accuracy and usefulness of analytic energy models for contemporary multicore processors | This paper presents refinements to the execution-cache-memory performance

relevant parameters su... | 1 | 0 | 0 | 0 | 0 | 0 |
A Simple Solution for Maximum Range Flight | Within the standard framework of quasi-steady flight, this paper derives a
speed that realizes the maximal obtainable range per unit of fuel. If this
speed is chosen at each instant of a flight plan $h(x)$ giving altitude $h$ as
a function of distance $x$, a variational problem for finding an optimal $h(x)$

Multiscale Residual Mixture of PCA: Dynamic Dictionaries for Optimal Basis Learning | In this paper we are interested in the problem of learning an over-complete

On factorizations of graphical maps | We study the categories governing infinity (wheeled) properads. The graphical
category, which was already known to be generalized Reedy, is in fact an
Eilenberg-Zilber category. A minor alteration to the definition of the wheeled
graphical category allows us to show that it is a generalized Reedy category.

Raking-ratio empirical process with auxiliary information learning | The raking-ratio method is a statistical and computational method which
adjusts the empirical measure to match the true probability of sets in a finite

Improving drug sensitivity predictions in precision medicine through active expert knowledge elicitation | Predicting the efficacy of a drug for a given individual, using

knowledge offers a promising a... | 1 | 0 | 0 | 1 | 0 | 0 |
On Vague Computers | Vagueness is something everyone is familiar with. In fact, most people think

Exploiting OxRAM Resistive Switching for Dynamic Range Improvement of CMOS Image Sensors | We present a unique application of OxRAM devices in CMOS Image Sensors (CIS)

Magnetic control of Goos-Hanchen shifts in a yttrium-iron-garnet film | We investigate the Goos-Hanchen (G-H) shifts reflected and transmitted by a
yttrium-iron-garnet (YIG) film for both normal and oblique incidence. It is
found that the nonreciprocity effect of the MO material does not only result in
a nonvanishing reflected shift at normal incidence, but also leads to a

Effective mass of quasiparticles from thermodynamics | We discuss the potential advantages of calculating the effective mass of

Dynamics over Signed Networks | A signed network is a network with each link associated with a positive or

economic sys... | 1 | 0 | 0 | 0 | 0 | 0 |
On the Estimation of Entropy in the FastICA Algorithm | The fastICA algorithm is a popular dimension reduction technique used to

The Accuracy of Confidence Intervals for Field Normalised Indicators | When comparing the average citation impact of research groups, universities
