Gene synthesis is hampered by two obstacles: improper assembly of oligonucleotides; oligonucleotide defects incurred during chemical synthesis. To overcome the first problem, we describe the employment of a Computationally Optimised DNA Assembly (CODA) algorithm that uses the degeneracy of the genetic code to design overlapping oligonucleotides with thermodynamic properties for self-assembly in...

This paper proposes a model of differential tonal perception in which perception of tonal movement in spoken language i s influenced by syllable structure. In the proposed model, tonal movement at syllable onset is perceptually coded differently from movement in the syllable nucleus or in the coda. An F0 contour through the syllable onset or at the beginning of the nucleus is coded as a level t...

In the ongoing CODA project, we are developing a system for automatically converting monologue into dialogue. The dialogue is generated in a two-step approach. Firstly, snippets of input monologue are mapped to dialogue act sequences. Secondly, these sequences are verbalized. The conversion relies partly on analysing input monologue in terms of its discourse relations. This short paper briefly ...

The present study aims to explore how phonological, morphological and prosodic features of an utterance affect perception of English codas by Mandarin listeners. A phoneme detection task was conducted with the word-final target phoneme /s/ appearing utterance-medially or finally in various phonological (consonant cluster vs. singleton) and morphological (plural morpheme vs. coda of a stem word)...

Previous research shows that two-year-olds’ third person singular -s and plural -s are produced more accurately in utterance-final compared to utterance-medial position. However, only the third person singular is affected by coda complexity. This study explores these effects with possessive -s. Acoustic analysis of twelve two-year-olds’ elicited imitations examined the use of simple versus comp...

Effective coordination of distributed human planners requires timely communication of relevant information to ensure the overall coherence of activities and the compatibility of assumptions. This paper presents a framework called CODA that provides targeted information dissemination among distributed human planners as a way of improving coordination. Within CODA, each planner declares interest ...

The accuracy of scattered Rayleigh waves estimated using an interferometric method is investigated. Summing the cross correlations of the wave fields measured all around the scatterers yields the Green's function between two excitation points. This accounts for the direct wave and the scattered field (coda). The correlations themselves provide insights into the location of the scatterers, as we...

A perception study with acoustically manipulated tokens sought to establish the relative weight of noise vs. formant transition cues in the perception of stop place of articulation by Polish listeners, and to replicate previous findings from a crowdsourced experiment. Results suggest that noise cues are primary for Poles in stop place identification. It is argued that this finding is compatible...

This study investigates phonetic factors – vocalic/consonantal context, duration, stress favouring rhotic perception of the lateral approximant in Greek. Nonsense words containing the lateral in different lengths in both intervocalic and internal coda position, alongside similar words containing a rhotic, were presented to Greek listeners for categorisation as /l/ or /r/. Results showed that la...
