We experimentally generate high-coherence primary Kerr combs with multiple sub-lines by using dual pumps and demonstrate the application of a primary comb state in multichannel communications. We find that more than 10 primary comb lines can be generated within the spectrum of modulation instability gain in our microring resonator. The generation is also verified by numerical simulations and th...

Very High-Speed Digital Subscriber Lines upstream transmission suffers from strong far end crosstalk (FEXT) by the shortest lines in a multiuser communication environment. This problem called “Near-Far Effect” drastically reduces the upstream capacity on the longer lines. Power control algorithms effectively handle this problem and maximize the achievable data rate region, given an average powe...

The possibility of quantum key distribution in the atmosphere has been experimentally demonstrated by coupling commercially available units designed for fiber-optic communication lines with atmospheric optical terminals. For distances up to 3100 m, data on losses a channel an path were obtained and influence systems intelligent adjustment terminals synchronization system blocks was studied. It ...

This communication utilises Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) combined with multivariate analysis to obtain spectra from the surfaces of three closely related cell lines allowing their discrimination based upon mass spectral ions.

We present a new model that combines ideas from corporate memory structures with concepts from epistemology to introduce a way of modelling group knowledge. Individual belief systems are combined with communication lines and certainty levels in a way that reflects how group knowledge is built up. We show how this model can be used to identify communication groups as well as to extract shared be...

Motivated by implementing collective communication operations on a network of processors connected via ethernet and similar bus lines, a problem of scheduling a dance party is formulated. The problem is solved by two algorithms based on searching and divide-and-conquer that generate suboptimal schedules and an algorithm based on graph factorization that generates optimal schedules. It is shown ...

The effects of potential neurohormones on the intracellular concentrations of adenosine 3':5'-cyclic monophosphate have been examined with three clonal lines of cultured glial tumors. In all cases, norepinephrine and isoproterenol produced striking elevations of the intracellular concentrations of the cyclic nucleotide. The response was mediated by a beta-adrenergic receptor. This effect is hyp...

purpose: to investigate the factors affecting communicational skills of regimental commanders toward conscripts at an army introductory military training center in tehran. materials and methods: the participants were 82 regimental commanders of the regiments and battalions of an introductory military training center. a 21-item questionnaire was used to collect the required data. descriptive and...

The presented integrated communication model corresponds to a computer simulation model used for computation of communication characteristics of an arbitrary HV overhead power-line channel. The simulated characteristics are suitable for analysis of the digital communications techniques application for highspeed data transmission over HV power lines. The integrated model is implemented as Matlab...

Dimming system using the wire or wireless communication method is used for the LED light dimming. This system requires a separate communication lines and modem. Such requirements have problems that installation cost increase and compatibility is low. Therefore, these methods are not suitable to apply indoor light. In this paper, we describe the dimming controller to solve problems in convention...
