Architecture without Content 4: Necessary Architecture

Kersten Geers, Andrea Zanderigo

The Data Center is the most definitive and yet invisible typology of our contemporary world. It is the densest spot in our digital universe, a physically invisible space virtually visited by many. In a time when the collective spirit of the net itself is m ...

Shared annotations: the social side of exam preparation

Pierre Dillenbourg, Andrea Mazzei

In this paper we show how the deployment of a lightweight note sharing system can restore the antique social vocation of annotations in the classroom. The system was designed for the classroom context and evaluated through a longitudinal study lasting for ...

Mycobacterium tuberculosis EspB binds phospholipids and mediates EsxA-independent virulence

Stewart Cole, Neeraj Dhar, Florence Pojer, Stefanie Boy-Röttger, Ming Zhang, Jan Lars Rybniker, Jeffrey Chen

The type-VII ESX-1 secretion apparatus, encoded by the esx-1 genetic locus, is essential for the export of EsxA and EsxB, two major virulence factors of Mycobacterium tuberculosis. ESX-1 also requires the products of the unlinked espACD operon for optimal ...

On equalities involving integrals of the logarithm of the Riemann zeta-function and equivalent to the Riemann hypothesis

By using the generalized Littlewood theorem about a contour integral involving the logarithm of an analytic function, we show how an infinite number of integral equalities involving integrals of the logarithm of the Riemann zeta-function and equivalent to ...

Extent-based incremental identification of reaction systems using concentration and calorimetric measurements

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan, Nirav Pravinbhai Bhatt

Extent-based Incremental Model Identification (IMI) uses the concept of extent of reaction and the integral method of parameter estimation to identify reaction kinetics from transient concentration measurements. This study proposes to incorporate calorimet ...

Extent-based incremental identification of reaction systems using concentration and calorimetric measurements

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Extent-based incremental identification uses the concept of extents and the integral method of parameter estimation to identify reaction kinetics from concentration measurements. The approach is rather general and can be applied to open both homogeneous an ...

Incremental Identification of Reaction Systems - A Comparison between Rate-based and Extent-based Approaches

Dominique Bonvin, Michael Amrhein, Nirav Pravinbhai Bhatt

An incremental identification approach for determining the kinetics of homogeneous reaction systems from transient concentration measurements has been developed in previous work (Marquardt, W. Chemical Engineering Research and Design 83(A6), 561–573, 2005) ...

On the direct evaluation of surface integral equation impedance matrix elements involving point singularities

Juan Ramon Mosig

The direct evaluation method tailored to the 4-D singular integrals over vertex adjacent triangles, arising in the first-kind and second-kind Fredholm surface integral equation formulations, is presented. A combination of singularity cancellation, reorderi ...

Fast and accurate computation of hyper-singular integrals in Galerkin surface integral equation formulations via the direct evaluation method

Juan Ramon Mosig

Hypersingular 4-D integrals, arising in the Galerkin discretization of surface integral equation formulations, are computed by means of the direct evaluation method. The proposed scheme extends the basic idea of the singularity cancellation methods, usuall ...
