Many organizations maintain identity information for their customers, vendors, and employees, etc. However, identities being compromised cannot be retrieved effectively. In this paper we first present a case study on identity problems existing in a local police department. The study show that more than half of the sampled suspects have altered identities existing in the police information syste...

We construct a class of 4D `yoga' (naturally relaxed) models for which the gravitational response heavy-particle vacuum energies is strongly suppressed. The contain three ingredients: (i) relaxation mechanism, (ii) very supersymmetric gravity sector coupled to matter supersymmetry non-linearly realised, and (iii) an accidental approximate scale invariance expressed through presence low-energy d...

Let A be a Banach algebra with a bounded left approximate identity. The Cohen Factorization Theorem is used to prove several results concerning the representation theory of A.

Tau proteins are major microtubule-associated proteins (MAPs), which promote polymerization of tubulin and determine spacings between microtubules in axons of both the central and peripheral nervous systems (CNS and PNS). Here, we cloned and identified a tau-like protein BmTau from silkworm, Bombyx mori (GenBank accession number FJ904935). The coding sequence of BmTau is 723 bases long and enco...

Potassium currents were measured using the three-microelectrode voltage-clamp technique in rat omohyoid muscle at temperatures from 1 to 37 degrees C. The currents were fitted according to the Hodgkin-Huxley equations as modified for K currents in frog skeletal muscle (Adrian et al., 1970a). The equations provided an approximate description of the time course of activation, the voltage dependen...

We consider the problem of approximate sorting of a data stream (in one pass) with limited internal storage where the goal is not to rearrange data but to output a permutation that reflects the ordering of the elements of the data stream as closely as possible. Our main objective is to study the relationship between the quality of the sorting and the amount of available storage. To measure qual...

A dynamic crack tip equation of motion is proposed based on the autonomy of the near-tip nonlinear zone of scale l(nl), symmetry principles, causality, and scaling arguments. Causality implies that the asymptotic linear-elastic fields at time t are determined by the crack path at a retarded time t-tau(d), where the delay time tau(d) scales with the ratio of l(nl) and the typical wave speed c(nl...

We continue the investigation of notions of approximate amenability that were introduced in work of the second and third authors together with R. J. Loy. It is shown that every boundedly approximately contractible Banach algebra has a bounded approximate identity, and that the Fourier algebra of the free group on two generators is not operator approximately amenable. Further examples are obtain...
