Special Session 18: Topological Dynamics
Spacing subshifts are a class of subshifts of a full shift on two symbols, defined in a superficially similar fashion to S-gap shifts. They were introduced by Lau and Zame in 1973 to give accessible examples of maps that are weakly (topologically) mixing but not strongly mixing, but have attracted little attention since. This talk will discuss the variety of topological dynamical behaviours the...
متن کاملDimethyl 7a-carbonyl-2-methoxy-7a,7a-bis(triphenylphosphino)-7a-ruthena-1-benzofuran-4,7-dicarboxylate
The crystal structure of the title compound, [Ru(C(12)H(12)O(6))(C(18)H(15)P)(2)(CO)], confirms its formulation as a ruthenabenzofuran, with a slightly distorted octa-hedral coordination environment at the Ru(II) ion, and mutually trans triphenyl-phosphine ligands. The metallabicyclic ring system is essentially planar (maximum deviation 0.059 Å).
متن کاملSynthesis and Biological Evaluation of 7a,7a,7a,8a,8a,8a- Hexafluororiboflavin and 7a,7a,7a,8a,8a,8a-Hexafluoro-FM N
7a,7a,7a,8a,8a,8a-H exafluororiboflavin (4) has been prepared and its oxidation-reduction potential determined polarographically to be + 0.02 V with respect to the standard hydrogen electrode. Compound 4 does not by itself promote the growth o f Lactobacillus casei. However, in the presence o f low riboflavin (1) concentrations, the hexafluoro analog 4 has som e growth enhancing activity. The F...
متن کاملSummary for the Theory Session at EC-18
A brief review of the theory contributions presented in the EC-18 Workshop is given. The covered spectrum of topics is quite broad including the electron cyclotron wave propagation physics as well the results of numerical modelling of transport and current drive.
متن کاملISSCC 2006 / SESSION 18 / CLOCK AND DATA RECOVERY / 18 . 5 18 . 5 A 3 . 2 Gb / s Semi - Blind - Oversampling CDR
A blind-oversampling CDR tracks the high-frequency jitter of the input data stream, but is limited at low-frequencies by the size of its FIFO [1]. A phase-tracking CDR, on the other hand, tracks jitter at frequencies below f3dB of its loop filter, but performs poorly beyond this frequency [2]. In this paper, a semi-blind-oversampling technique is presented. The proposed technique produces a jit...
