Building on the work of Terwilliger, we find the structure of nonthin irreducible T -modules of endpoint 1 for Pand Q-polynomial association schemes with classical parameters. The isomorphism class of such a given module is determined by the intersection numbers of the scheme and one additional parameter which must be an eigenvalue for the first subconstituent graph. We show that these modules ...

Phenoxybenzamine causes a long-lasting inactivation of the opiate receptors of the pand 8-type in homogenates of guinea-pig brain. This effect is selectively prevented when, before exposure to phenoxybenz­ amine, the homogenate is pre-incubated with ligands of high affinity for either of the two binding sites, i.e. dihydromorphine for the p-receptor and Tyr-D-Ala-Gly-Phe-D-Leu for the 8-recepto...

The band structure of 2D photonic crystals and their eigenmodes can be efficiently computed with the finite element method (FEM). For second order elliptic boundary value problems with piecewise analytic coefficients it is known that the solution converges extremly fast, i.e. exponentially, when using p-FEM for smooth and hp-FEM for polygonal interfaces and boundaries. In this article we discre...

Generalizing the P-property of a matrix, Gowda et al. [Gowda, M. S., R. Sznajder, J. Tao. 2004. Some P-properties for linear transformations on Euclidean Jordan algebras. Linear Algebra Appl. 393 203–232] recently introduced and studied Pand globally uniquely solvable (GUS)-properties for linear transformations defined on Euclidean Jordan algebras. In this paper, we study the invariance of thes...

Biaxial tensile strained Si grown on SiGe virtual substrates will be incorporated into future generations of CMOS technology due to the lack of performance increase with scaling. Compressively strained Ge-rich alloys with high hole mobilities can also be grown on relaxed SiGe. We review progress in strained Si and dual channel heterostructures, and also introduce high hole mobility digital allo...

A monopole or a dipole source in a fluid borehole generates acoustic waves, part of which propagate along the borehole and the other part enter the formation propagating as Por S-waves. The refracted waves propagating along the borehole wall are used to determine Pand S-wave velocities. However, a significant fraction of the seismic energy radiates into the formation. In this laboratory study, ...

The task of hardware (CMOS) implementation of artificial neuron is discussed. The main part of the device is a @-comparator which is a voltage divider formed by pand n-transistors. This approach is based on the possibility of ratio form representation of an arbitrary threshold function. The weight of the input is determined by the limitation of the current through the n-transistor that is equiv...

A novel approach to image mosaicking from MPEG video is presented in this paper. The motion vectors in both Pand Bframes are used for global motion estimation. The bi-directional information in B-frames provides multiple routes to warp a frame to its previous anchor frame. A Least Median of Squares based algorithm is adopted for robust motion estimation. In the case of a large proportion of out...

For MPEG-4 AVC/H.264 video encoders, the paper describes a model that defines a relationship between the number of bits for texture information and the quantization step size Q. The model is derived individually for I-, Pand B-frames. The model is defined by formulas given individually for 3 intervals covering whole eligible range of Q values. Extensive experiments with numerous test video sequ...

Gluon field configurations with nonzero topological charge induce Pand CP-odd effects. Such configurations are likely to be produced during heavy ion collisions. In this article, I will argue that in the intense (electromagnetic) magnetic field produced in non-central heavy ion collisions, topological charge creates an electromagnetic current in the direction of the magnetic field. This is the ...
