Solution of Bin Packing Instances in Falkenauer T Class: Not So Hard

Algorithms
In this work, the Bin Packing combinatorial optimization problem is studied from the practical side. The focus is on the Falkenauer T benchmark class, which is a collection of 80 problem instances that are considered hard to handle algorithmically ...

Fermionic Collective Modes of an Anisotropic Quark-Gluon Plasma

, 2006
We determine the fermionic collective modes of a quark-gluon plasma which is anisotropic in momentum space. We calculate the fermion self-energy in both the imaginary- and real-time formalisms and find that numerically and analytically (for two special ...

Tunnel face stability in strata rich in water with soft upper and hard lower layers

Scientific Reports
When a shield tunnel is excavated in water-rich strata with soft upper and hard lower layers, the failure mode of the tunnel face may shift from an overall failure mode to a partial failure mode.

Selective tuning of optical modes in a silicon comb-like photonic crystal cavity

Nanophotonics, 2019
Realizing multiply resonant photonic crystal cavities with large free spectral range is key to achieve integrated devices with highly efficient nonlinear response, such as frequency conversion, four-wave mixing, and parametric oscillation.

Chemical Instabilities and Broken Symmetry: The Hard Mode Case

, 1981
Chemical instabilities are interesting for the theorist for several reasons. The most important to our purposes are the following. These instabilities occur far out of thermal equilibrium and ordered states may appear through space or time symmetry breaking. In the vicinity of the transition points anomalies in the static and dynamical behaviour of the

Lattice and Continuum Theories

, 1994
We investigate path integral formalism for continuum theory. It is shown that the path integral for the soft modes can be represented in the form of a lattice theory.
