A partial-wave analysis of all pp scattering data below 925 MeV/c antiproton laboratory momentum is presented. The method used is adapted from the Nijmegen phase-shift analyses of pp and np scattering data. We solve the Schrödinger equation for the coupled pp and nn channels where the long-and intermediate-range interactions are described by a theoretically well-founded potential. This gives th...

Introduction: Uniform fat signal suppression is often difficult to achieve in a 3.0 Tesla MR system due to magnetic field inhomogeneity and/or B1 inhomogeneity. DWIBS [1] has been proposed as a new method of diffusion MRI that suppresses background signal. In DWIBS, non-negligible fat signals often remain after fat suppression methods are used and the residual fat signals often considerably deg...

— A new neptunium fluorozirconate glass (NpBasZrnF*) has been prepared and its Mossbauer spectrum was measured at 4.2 K and 77 K. Two resonance lines were observed. One is assigned to the Np ions occupying the normal Np sites in the compound. The other is thought to arise from Np which has replaced some of the Ba ions. The isomer shift of those ions suggests a configuration near 5f 6d . The Np ...

We consider several computational problems related to conjugacy between subshifts of finite type, restricted k -block codes: verifying a proposed conjugacy, deciding if two shifts admit and reducing the representation size shift via conjugacy. give polynomial-time algorithm for verification, show GI - NP -hardness size, respectively. Our approach focuses on 1-block conjugacies vertex shifts, fr...

Limited bandwidth, multipath-induced signal fading, and motion-induced Doppler effect makes underwater acoustic (UWA) communication still an ongoing challenge. Among numerous interesting researches on UWA communication, the application of orthogonal signal division multiplexing (OSDM) has been proposed by authors. In our previous work, it was found that the UWA communication with OSDM achieves ...

We study the question of whether the class DisjNP of disjoint pairs (A,B) of NPsets contains a complete pair. The question relates to the question of whether optimal proof systems exist, and we relate it to the previously studied question of whether there exists a disjoint pair of NP-sets that is NP-hard. We show under reasonable hypotheses that nonsymmetric disjoint NP-pairs exist, which provi...
