A programmable switch based on a DNA hairpin loop is functionalised with a rigid or flexible porphyrin or FAM and TAMRA FRET pair, which provides insight into the restructuring of the hairpin as well as porphyrin-porphyrin coupling. The switch contains five discrete states which can be accessed independently and followed by real-time spectroscopy, opening the way to a quinary computing code.

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...

The ability to adjust behavior to sudden changes in the environment develops gradually in childhood and adolescence. For example, in the Dimensional Change Card Sort task, participants switch from sorting cards one way, such as shape, to sorting them a different way, such as color. Adjusting behavior in this way exacts a small performance cost, or switch cost, such that responses are typically ...

In the computer market open interfaces have paved the way for intense competition with dynamic and rapid market evolution as a result. Open switch interfaces could in a similar way change the market conditions for the switch and router industry and in addition result in a more diversified telecommunication market. This Invited Lecture provides an overview of the new system architecture that the...

This paper describes a new architecture for a multicast ATM switch scalable from a few tens to a few thousands of input ports. The switch, called the Abacus switch, has a nonblocking switch fabric followed by small switch modules at the output ports. It has buffers at input and output ports. Cell replication, cell routing, output contention resolution, and cell addressing are all performed in a...

acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. the conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. it has been rarely reported in the literature. in leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. herein, we rep...

conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardi...

One of the reasons that topological methods have a limited popularity for the visualization of complex 3D flow fields is the fact that their topological structures contain a number of separating stream surfaces. Since these stream surfaces tend to hide each other as well as other topological features, for complex 3D topologies the visualizations become cluttered and hardly interpretable. One so...

Since in the future, the demand on broadband services (e.g. Lan and video interconnection services) is likely to increase, research is focusing on the introduction of the Broadband ISDN. In 1989 standards on the transfer mode for B-ISDN were introduced: ATM. From then a lot of ATM switch designs were introduced, but they all assume the VLSI technology to be more developed than it actually is. T...
