we consider the transitive linear maps on the operator algebra $b(x)$for a separable banach space $x$. we show if a bounded linear map is norm transitive on $b(x)$,then it must be hypercyclic with strong operator topology. also we provide a sot-transitivelinear map without being hypercyclic in the strong operator topology.

Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...

The topology of OxlT, the oxalate:formate exchange protein of Oxalobacter formigenes, was established by site-directed fluorescence labeling, a simple strategy that generates topological information in the context of the intact protein. Accessibility of cysteine to the fluorescent thiol-directed probe Oregon green maleimide (OGM) was examined for a panel of 34 single-cysteine variants, each gen...

We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS3 with a sevendimensional internal space. In one duality frame the only other nonvanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to give infinite families of globally well-defined solutions of type IIB s...

This paper presents a zero-skew gated clock routing technique for VLSI circuits. The gated clock tree has masking gates at the internal nodes of the clock tree, which are selectively turned on and off by the gate control signals during the active and idle times of the circuit modules to reduce switched capacitance of the clock tree. The clock tree topology is constructed based on the locations ...

We investigate the delocalization transition appearing in an exclusion process with two internal states, respectively on two parallel lanes. At the transition, delocalized domain walls form in the density profiles of both internal states, in agreement with a mean-field approach. Remarkably, the topology of the system's phase diagram allows for the delocalization of a (localized) domain wall whe...

We describe a method for transforming asynchronous network protocols into protocols that can sustain any transient fault, i.e., become self-stabilizing. We combine the known notion of local checking with a new notion of internal reset, and prove that given any self-stabilizing internal reset protocol, any locally-checkable protocol can be made self-stabilizing. Our proof is constructive in the ...

The internal space for a molecule, atom, or other n-body system can be conveniently parameterised by 3n − 9 kinematic angles and three kinematic invariants. For a fixed set of kinematic invariants, the kinematic angles parameterise a subspace, called a kinematic orbit, of the n-body internal space. Building on an earlier analysis of the threeand four-body problems, we derive the form of these k...

We use the polygon representation of 2+1–dimensional gravity to explicitly carry out the canonical quantization of a universe with the topology of a torus. The mapping-classinvariant wave function for a quantum ”big bounce”, is reminiscent of the interference patterns of linear gratings. We consider the “problem of time” of quantum gravity: for one choice of internal time the universe recovers ...

Cloud manufacturing is characterized by large uncertainties and disturbances due to its networked, distributed, loosely coupled features. To target the problem of frequent cloud resource node failure, this paper proposes (1) three substitution strategies based on redundancy (2) a new robustness analysis method for systems combination complex network multi-agent simulation. First, simulation mod...
