The emergence of third-generation, technology-based public bikeshare schemes offers new opportunities for researching cycling behaviour. In this study, data from one such scheme, the London Cycle Hire Scheme (LCHS), are analysed. Algorithms are developed for summarising and labelling cyclists’ usage behaviours and tailored visual analysis applications are designed for exploring their spatiotemp...

Abstract The article proposes an addition to the tunnel parsing algorithm that enables it parse grammars having countable repetitions and configurations of grammar elements generating empty words without refactoring grammar. equivalency trees built by use ambiguous is discussed. class ε-ambiguous defined as a subclass relative these trees. ε-deterministic are then grammars. A technique for line...

Several papers have published very specific threats to wireless networks—specifically in the area of attacks against the IEEE 802.11 Wired Equivalency Protocol (WEP). Other papers have addressed wireless attacks based on the attack models used in wired networks. However, the different characteristics of wireless networks require looking at the threat differently. We present a Wireless Threat Ta...

We show that formally for the standard ansatz relativistic point-coupling mean-field (RMF-PC) model a lagrangian density L is not equivalent in Hartree and Hartree-Fock approximations. The equivalency can be achieved only if we use a " complete " ansatz at the cost of introducing new parameters in the model. An approximate treatment of the exchange terms from standard RMF-PC indicates that thes...

This paper contains more examples to formerly introduced concept of formal language equivalency. That is, for two models, there is a substitution by which we change each string of every yield sequence in one model so that sequence ofs string resulting from this change represents a yield sequence in the other equvalent model, these two models closely simulates each other; otherwise they do not. ...

Antigens derived from three different yeast strains of Histoplasma capsulatum (GW and VC used by the Veterans Administration Serology Reference Laboratory and the Centers for Disease Control reference antigen, A811) were compared with each other to determine their equivalency. Results from 200 sera, tested concurrently by the Serology Reference Laboratory and the University of Kentucky Mycosero...

We suggest that both of these underlying assumptions, as of this point, are unproven. Moreover, we suggest that this proposed approach ignores a rather wellestablished fact of basic reproductive biology, namely that any form of cryopreservation to some degree negatively affects pregnancy and live birth chances. For example, claims of equivalency between fresh and cryopreserved donor oocytes wer...
