    Background: How do listeners manage to recognize words in an unfamiliar language? The physical continuity of the signal, in which real silent pauses between words are lacking, makes it a difficult task. However, there are multiple cues that can be exploited to localize word boundaries and to segment the acoustic signal. In the present study, word-stress was manipulated with statistical information and placed in different syllables within trisyllabic nonsense words to explore the result of the combination of the cues in an online word segmentation task. Results: The behavioral results showed that words were segmented better when stress was placed on the final syllables than when it was placed on the middle or first syllable. The electrophysiological results showed an increase in the amplitude of the P2 component, which seemed to be sensitive to word-stress and its location within words. Conclusion: The results demonstrated that listeners can integrate specific prosodic and distributional cues when segmenting speech. An ERP component related to word-stress cues was identified: stressed syllables elicited larger amplitudes in the P2 component than unstressed ones

    Developing standards for interoperability of tactical communications systems

    The lack of interoperability in tactical communications systems has been a known fact in the North AtlanticTreaty Organization (NATO) since the end of the Cold War. This condition still exists today. The only alternative to obtain tactical communications systems with the interoperability necessitated by future operational requirements are through the establishment of NATO standards. This paper examines the tactical communications systems Post 2000 (TACOMS) project whose aim is to develop technical standards that will allow for achievement of interoperability between multinational tactical communications networks
