Pentaquark masses: another look
We refine theoretical estimates of the masses of the Θ and other pentaquark states. For the Karliner-Lipkin model, it is noted that for the qqq̄ triquark, proper incorporation of the colour-spin SU(6) symmetry has not been made in the literature. We address this lacuna, make a small generalization in the hyperfine interaction couplings used hitherto, and incorprate flavour symmetry breaking. Aft...
متن کاملAnother look at HMQV
The HMQV protocols are ‘hashed variants’ of the MQV key agreement protocols. They were introduced at CRYPTO 2005 by Krawczyk, who claimed that the HMQV protocols have very significant advantages over their MQV counterparts: (i) security proofs under reasonable assumptions in the (extended) Canetti-Krawczyk model for key exchange; and (ii) superior performance in some situations. In this paper w...
متن کاملAnother Look at Tightness
We examine a natural, but non-tight, reductionist security proof for deterministic message authentication code (MAC) schemes in the multi-user setting. If security parameters for the MAC scheme are selected without accounting for the non-tightness in the reduction, then the MAC scheme is shown to provide a level of security that is less than desirable in the multi-user setting. We find similar ...
متن کاملAnother Look at Graftels
We present a hybrid object-image algorithm for the placement of graftels in a scene. Our algorithm addresses the problem of frameto-frame coherency while maintaining image-space constraints. Graftels are attached to objects in the scene. Each graftel has a behavior function that determines its size and orientation based on the current view direction and image-space size. The placement of the gr...
متن کاملAnother Look at PMAC
We can view an existing Message Authentication Code (MAC) as a Carter-Wegman MAC in spite of the fact it may not have been designed as one. This will make the analysis easier than it has been when considered from other viewpoints. In this paper, we can look PMAC with two keys as a Carter-Wegman MAC and get a simple security proof for it. Using this viewpoint to look at PMAC, we will learn not o...
