Computing Gröbner fans

This paper presents algorithms for computing the Gröbner fan of an arbitrary polynomial ideal. The computation involves enumeration of all reduced Gröbner bases of the ideal. Our algorithms are based on a uniform definition of the Gröbner fan that applies ...

Uniform and staggered magnetizations induced by Dzyaloshinskii-Moriya interactions in isolated and coupled spin-1∕2dimers in a magnetic field

Frédéric Mila, Salvatore Manmana

We investigate the interplay of Dzyaloshinskii-Moriya interactions and an external field in spin-1∕2 dimers. For isolated dimers and at low field, we derive simple expressions for the staggered and uniform magnetizations which show that the orientation of ...

Analysis of actin filament network organization in lamellipodia by comparing experimental and simulated images

Jean-Jacques Meister, Sébastien Schaub

Protrusion of lamellipodia during cell migration depends on the assembly of actin network. The assembly mechanism, based on dendritic filament branching, has been investigated in reconstituted in vitro systems, but little is known about the dynamical and s ...

Which NICS Aromaticity Index for Planar pi Rings Is Best?

Five increasingly sophisticated aromaticity indexes, based on nucleus-independent chem. shifts (NICS), were evaluated against a uniform set of arom. stabilization energies (ASE) for 75 mono- and polyheterocyclic five-membered rings. While acceptable statis ...

Cubic and oriented Ag nano-particles by high vacuum evaporation

Libero Zuppiroli, Detlef Berner

Ag cubes of uniform size (70nm) and self-assembled into two dimensional arrays are formed by physical vapor deposition. The formation of the Ag cubes depends critically on the substrate composition. While heat dissipation can control the crystallization of ...

Measurements and consequences of nonuniform radio frequency plasma potential due to surface asymmetry in large area radio frequency capacitive reactors

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm, Lukas Derendinger

In large area reactors, a local asymmetry of the electrode area, due to lateral grounded walls, causes a perturbation in rf plasma potential, due to the redistribution of lateral rf current, which propagates along the resistive plasma between capacitive sh ...

A new look at atomic broadcast in the asynchronous crash-recovery model

André Schiper, Sergio Mena

Atomic broadcast in particular, and group communication in general, have mainly been specified and implemented in a system model where processes do not recover after a crash. The model is called crash-stop. The drawback of this model is its inability to ex ...

Chiral hexagonal cellular sandwich structure: A vibroacoutic assessment

Alessandro Spadoni

In this work we describe the vibroacoustic behavior of a novel concept of core for sandwich structures featuring auxetic characteristics, enhanced shear stiffhess and compressive strength compared to classical cellular cores in sandwich components for sand ...

Handling the Inconsistency of Relative Map Filter

Roland Siegwart

In \cite{martinelli_2004_open_challenges_in}, a version of Relative Map Filter (\RMF) is proposed to solve the simultaneous localization and map building (SLAM) problem. In the \RMF, the map states contain only quantities invariant under shift and rotat ...
