NxN Coupling Matrix Synthesis of Dissipative Microwave Filters

Michael Mattes, Francisco Edén Sorolla Rosario, Diego Navarro Tapia

In this communication, the coupling matrix synthesis of dissipative microwave filters is analyzed and compared to the synthesis of lossless filters. A modified definition of the vector matrix product allows using the same synthesis procedure in both cases. ...

Mitigating interference with integer-forcing architectures

Michael Christoph Gastpar

We show that the recently proposed integer-forcing linear receiver provides an attractive approach to the problem of mitigating external interference in MIMO channels. The integer-forcing receiver proceeds by first decoding a set of full rank integer linea ...

Compressive Sensing under Matrix Uncertainties: An Approximate Message Passing Approach

Volkan Cevher

In this work, we consider a general form of noisy compressive sensing (CS) when there is uncertainty in the measurement matrix as well as in the measurements. Matrix uncertainty is motivated by practical cases in which there are imperfections or unknown ca ...

Nonnegative Matrix Factorization and Spatial Covariance Model for Under-Determined Reverberant Audio Source Separation

Pierre Vandergheynst, Rémi Gribonval

We address the problem of blind audio source separation in the under-determined and convolutive case. The contribution of each source to the mixture channels in the time-frequency domain is modeled by a zero-mean Gaussian random vector with a full rank cov ...

Reduction theory for symmetry breaking with applications to nematic systems

François Gay-Balmaz, Cesare Tronci

We formulate Euler-Poincare and Lagrange-Poincare equations for systems with broken symmetry. We specialize the general theory to present explicit equations of motion for nematic systems, ranging from single nematic molecules to biaxial liquid crystals. Th ...

Applications of magnetic Labs-on-a-chip

Martinus Gijs

Using magnetic micro- and nanoparticles (beads) in microfluidic chips opens new perspectives for miniaturized applications in analytical sciences. Four important application areas of magnetic particles in microfluidic systems are discussed. The first one i ...

Fill-ins number reducing direct solver designed for FIT-type matrix

Michal Karol Dobrzynski, Jagoda Anna Dobrzynska

This paper investigates the particular problem of matrices appearing during the modeling of Integrated Circuits with Finite Integration Technique (FIT) method. We present the key points of FIT approach followed by an illustration of the structure and the p ...

A new extended matrix logarithm formulation for the simulation of viscoelastic fluids by spectral elements

Michel Deville, Nicolas Fietier, Azadeh Jafari

This study presents a new algorithm developed in order to remove instabilities observed in the simulation of unsteady viscoelastic fluid flows in the framework of the spectral element method. In this study, we consider a particular model of the finite exte ...

The 12th-14th type III repeats of fibronectin function as a highly promiscuous growth factor-binding domain

Jeffrey Alan Hubbell, Mikaël Martino

It has recently been shown that some growth factors (GFs) have strong interactions with nonproteoglycan extracellular matrix proteins. Relevant here, the 12th-14th type three repeats of fibronectin (FN III12-14) have been shown to bind insulin-like growth ...
