Extended Abstract This paper ooers three candidates for a deterministic, noninterleaving, behaviour model which generalizes Hoare traces to the noninterleaving situation. The three models are all proved equivalent in the rather strong sense of being equivalent as categories. The models are: deterministic labelled event structures, generalized trace languages in which the independence relation i...

We investigate the dynamic creation of fractionalized half-quantum vortices in Bose-Einstein condensates of sodium atoms. Our simulations show that both individual half-quantum vortices and vortex lattices can be created in rotating optical traps when additional pulsed magnetic trapping potentials are applied. We also find that a distinct periodically modulated spin-density-wave spatial structu...

The content of many communication services depend on the context, such as the user’s location. We describe a ’service’ URN that allows to register such context-dependent services that can be resolved in a distributed manner.

This study attempts to improve automatic phonetic segmentation within the HMM framework. Experiments were conducted to investigate the use of phone boundary models, the use of precise phonetic segmentation for training HMMs, and the difference between context-dependent and contextindependent phone models in terms of forced alignment performance. Results show that the combination of special one-...

In this paper, we take Determinative-Measure Compounds as an example to demonstrate how the E-HowNet semantic composition mechanism works in deriving the sense representations for all determinative-measure (DM) compounds which is an open set. We define the sense of a closed set of each individual determinative and measure word in E-HowNet representation exhaustively. We then make semantic compo...

We investigate various language famili$:s which can be obtained from sentential form languages of semi-Thue systems by applying codmgs, weak codings, non-erasing homomorphisms, and arbitrary homomorphi5rns. We also distinguish between monotone, contexi-independent, and context-dependent semi-Thur systems with at most one or finitely many starting words. Finally, we study the effect of erasing p...

Voltage-sensitive dye imaging (VSDI) is a powerful technique for measuring neural population responses from a large cortical region simultaneously with millisecond temporal resolution and columnar spatial resolution. However, the relationship between the average VSDI signal and the average spiking activity of neural populations is largely unknown. To better understand this relationship, we comp...

To understand sensory encoding and decoding, it is essential to characterize the dynamics of population responses in sensory cortical areas. Using voltage-sensitive dye imaging in awake, fixating monkeys, we obtained complete quantitative measurements of the spatiotemporal dynamics of V1 responses over the entire region activated by small, briefly presented stimuli. The responses exhibit severa...

This paper looks at improving unit selection text-to-speech (TTS) quality by optimizing the agreement between frontend and speech database. We focused, in particular, on two classes of problems causing degradation in synthesis quality: 1) realization of /d/ and /t/1 sounds and 2) confusions of unstressed vowels, especially with schwas. We investigated two approaches to tackling these problems. ...
