The Truncated Tracial Moment Problem

We present tracial analogs of the classical results of Curto and Fialkow on moment matrices. A sequence of real numbers indexed by words in noncommuting variables with values invariant under cyclic permutations of the indexes, is called a tracial sequence. ...

Numerical simulations with a first-order BSSN formulation of Einstein's field equations

Jan Sickmann Hesthaven

We present a new fully first-order strongly hyperbolic representation of the Baumgarte-Shapiro-Shibata-Nakamura formulation of Einstein's equations with optional constraint damping terms. We describe the characteristic fields of the system, discuss its hyp ...

Faster Squaring in the Cyclotomic Subgroup of Sixth Degree Extensions

Robert Granger

This paper describes an extremely efficient squaring operation in the so-called ‘cyclotomic subgroup’ of

\mathbb{F}_{q^6}

, for

q \equiv 1 \bmod{6}

. Our result arises from considering the Weil restriction of scalars of this group from

A Low-Noise CMOS Receiver Frontend for NMR-based Surgical Guidance

Giovanni Boero, Jens Anders

In this paper a novel architecture for an integrated NMR receiver front-end for surgical guidance applications is described. While the chip consumes only 9 mA supply current from a 3.3 V power supply it has a measured input referred noise density of 0.7 nV ...

A Low-Noise CMOS Receiver Frontend for MRI

Giovanni Boero, Jens Anders

In this paper a novel architecture for an integrated receiver front-end for micro magnetic resonance imaging (micro-MRI) applications is described. While the chip consumes only 9mA supply current (4mA in the LNA and 5mA in the output buffer) from a 33V pow ...

Spin-Wave Interference in Microscopic Rings

Dirk Grundler

We have studied the spin excitations of ferromagnetic rings and observed a distinct series of quantized modes in the vortex state. We attribute them to spin waves that circulate around the ring and interfere constructively. They form azimuthal eigenmodes o ...

EDITORIAL: Robot Programming By Demonstration

Aude Billard, Roland Siegwart

Programming by demonstration (PbD) is a key research topic in robotics. It impacts both fundamental research and application-oriented studies.Work in that area tackles the development of robust algorithms for motor control, motor learning, gesture recognit ...

Key improvements to XTR

Arjen Lenstra

This paper describes improved methods for XTR key representation and parameter generation (Lenstra et al., 2000). If the field characteristic is properly chosen, the size of the XTR public key for signature applications can be reduced by a factor of three ...
