Balanced ternary number representation and arithmetic, based on the symmetric radix-3 digit set {−1, 0, +1}, has been studied at various times in the history of computing. Among established advantages of balanced ternary arithmetic are representational symmetry, favourable error characteristics and rounding by truncation. In this study, we show an additional advantage: that of lower-error trunc...

We report on an extremely fast and versatile synthetic approach, based on microwave assisted sol-gel chemistry, that allows a conformal nanometric coating of intricate three-dimensional structures. Using this methodology, we have achieved a conformal coverage of large areas of three-dimensional opals with a superparamagnetic manganese ferrite layer, yielding magneto-photonic crystals with excel...

Ternary exclusive or is the (two valued) truth function that is true just in case exactly one of its three arguments is true. This is an interesting truth function, not definable in terms of the binary exclusive or alone, although the binary case is definable in terms of the ternary case. This article investigates the types of truth functions that can be defined by ternary exclusive or, and rel...

Functional interactions between the p75 neurotrophin receptor (p75NTR) and the Trk receptors were demonstrated several years ago, but their mechanistic basis remains uncertain. In this issue of Neuron, Wehrman et al. provide a three-dimensional structure of the full TrkA ectodomain complexed to NGF and examine the possibility of a ternary p75NTR-NGF-TrkA complex.

We show that each irreducible tensor representation of weight 2 the rotation group in space rank 3 tensors over three-dimensional gives rise to an associative algebra with unity. find algebraic conditions be satisfied by generators these algebras. Part relations is binary, and another part ternary type. The structure latter one based on use cyclic [Formula: see text] generated primitive cubic r...

The Hierarchical Heavy Hitters problem extends the notion of frequent items to data arranged in a hierarchy. This problem has applications to network traffic monitoring, anomaly detection, and DDoS detection. We present a new streaming approximation algorithm for computing Hierarchical Heavy Hitters that has several advantages over previous algorithms. It improves on the worst-case time and spa...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...
