Dynamical systems can often be decomposed into loosely coupled subsystems. The system of ordinary differential equations (ODEs) modelling such a problem can then be partitioned corresponding to the subsystems, and the loose couplings can be exploited by special integration methods to solve the problem using a parallel computer or just solve the problem more efficiently than by standard methods....

The presence of charge promotes the propensity of a rotating black hole to support the propagation of electromagnetic plane waves with negative phase velocity (NPV) in its ergosphere, whether the Kerr–Newman or the Kerr–Sen metric descriptions of spacetime are considered. Striking differences in the NPV characteristics for the Kerr–Newman and Kerr–Sen metrics emerge from numerical studies, part...

Recent work has introduced fork-decoupled search, addressing classical planning problems where a single center component provides preconditions for several leaf components. Given a fixed center path ⇡ C , the leaf moves compliant with ⇡C can then be scheduled independently for each leaf. Forkdecoupled search thus searches over center paths only, maintaining the compliant paths for each leaf sep...

In multicore processor systems, last-level caches (LLCs) play a crucial role in reducing system energy by i) filtering out expensive accesses to main memory and ii) reducing the time spent executing in high-power states. Cache compression can increase effective cache capacity and reduce misses, improve performance, and potentially reduce system energy. However, previous compressed cache designs...

Variational Gaussian (VG) inference methods that optimize a lower bound to the marginal likelihood are a popular approach for Bayesian inference. A difficulty remains in computation of the lower bound when the latent dimensionality L is large. Even though the lower bound is concave for many models, its computation requires optimization over O(L) variational parameters. Efficient reparameterizat...

Antenna arrays are likely to be an important feature of future mobile communication systems. With an antenna array, mobile users can be separated by a spatial filtering procedure allowing several users on the same carrier frequency. The uplink part (mobile to base) not only can, but is better solved without using any spatial knowledge in terms of direction of arrival (DOA). However, DOA estimat...

On total reflection from a half–space filled with an isotropic, homogeneous, weakly dissipative, dielectric–magnetic medium with negative phase–velocity (NPV) characteristics , it is shown here that a linearly polarized beam can experience either a negative or a positive Goos–Hänchen shift. The sign of the shift depends on the polarization state of the beam as well as on the signs of the real p...

Previously, we have reported that a gene encoding Bombyxmoriβ-N-acetylglucosaminidase 2 (BmGlcNA case2) has been identified differentially expressed in the midgut of Bombyxmori strain NB resistant to nucleopolyhedrovirus (BmNPV), strain 306 susceptible to NPV and a near isogenic line BC9 with similar genetic background to 306 but resistant to NPV by two-dimensional gel electrophoresis (2-DE).
