The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. A cable model has therefore been worked out based upon the high frequency properties of the cable insulation and conductor systems. ...

During transmembrane signaling by Escherichia coli Tsr, changes in ligand occupancy in the periplasmic serine-binding domain promote asymmetric motions in a four-helix transmembrane bundle. Piston displacements of the signaling TM2 helix in turn modulate the HAMP bundle on the cytoplasmic side of the membrane to control receptor output signals to the flagellar motors. A five-residue control cab...

New developments in nonlinear dynamical systems are permitting Volterra and Wiener nonlinear functional series representations to be optimally approximated by artificial neural networks, which are capable of adaptation, learning and evolution by training with or without supervision.The framework based on Generalized Fock Space, enabling these developments is briefly reviewed. In particular, the...

Goddard Space Flight Center is conducting a search for space flight worthy fiber optic cable assemblies that will benefit all projects at all of the NASA centers. This paper is number two in a series of papers being issued as a result of this task to define and qualify space grade fiber optic cable assemblies. Though to qualify and use a fiber optic cable in space requires treatment of the cabl...

This paper will be a comparative analysis of those two leading data link layer protocols, Ethernet and ATM, which are currently being used in local cable systems worldwide. These two protocols will be evaluated to determine technical (network architecture), management (network management) and the financial costs (economics) of implementing each. Which protocol will emerge as the primary protoco...

In this paper, a three dimensional analysis is performed to investigate the static instability of long-span cable-stayed bridges due to wind loading. Cables made of carbon fiber composite cable (CFCC) are studied. Nonlinearity due to displacement-dependent wind loading is considered. A 1400meter cable-stayed bridge model is used to investigate the static behavior of bridges with both steel and ...

Although much effort has been devoted in the last decade to solve the problem of synthesizing the frequency dependent transformation matrix in unbalanced multiphase cable system, we believe the best solution is to completely eliminate the necessity of the frequency dependent transformation matrix. This paper presents advances in the development of a new cable model (zCable) which splits the rep...

Creep behavior of thick-walled functionally graded cylinder consisting of AlSiC and subjected to internal pressure and high temperature has been analyzed. The functional relationship between strain rate with stress can be described by the well known threshold stress based creep law with a stress exponent of five. The effect of imposing non-linear particle gradient on the distribution of creep s...

Inclined cables are essential structural elements that are used most prominently in cable stayed bridges. When the bridge deck oscillates due to an external force, such as passing traffic, cable vibrations can arise not only in the plane of excitation but also in the perpendicular plane. This undesirable phenomenon can be modelled as an auto-parametric resonance between the in-plane and out-of-...

BACKGROUND Formins are a conserved family of actin nucleators responsible for the assembly of diverse actin structures such as cytokinetic rings and filopodia. In the fission yeast Schizosaccharomyces pombe, the formin for3p is necessary for the formation of actin cables, which are bundles of short parallel actin filaments that regulate cell polarity. These filaments are largely organized with ...
