Sonic display of HR changes during exercise helps both the patient and the investigator to better identify the transition from rest values to "exercise" zone. then crossing the "attention" threshold and reaching the "alert" threshold. Three types of sonic display were tested, based on combinations of saccadic sounds, different intensities and different pitch. The results indicate a clear prefer...

Traditional uses of virtual audio environments tend to focus on perceptually accurate acoustic representations. Though spatialization of sound sources is important, it is necessary to leverage control of the sonic representation when considering musical applications. The proposed framework allows for the creation of perceptually immersive scenes that function as musical instruments. Loudspeaker...

Sonic is the first prototype implementation of non-standard inferences for Description Logics that can be used via a graphical user interface. In addition to that our implementation extends an earlier implementation of the least common subsumer and of the approximation inference service to more expressive Description Logics, more precisely to Description Logics with number restrictions. Sonic o...

In Drosophila, it has been shown that protein kinase A and hedgehog have antagonistic actions during the formation of imaginal disks. In vertebrate skin, sonic hedgehog is expressed specifically in the feather bud epithelia. using an in vitro explant culture model we showed that dibutyryl cAMP, a protein kinase A (PKA) activator, suppresses the expression of Sonic hedgehog, (Shh) and continuous...

In this work we find the shape and dimension of the solar wind transition surfaces, namely the slow (sonic), the fast magnetosonic and the Alfvén surface, as a function of heliospheric latitude using actual experimental data from Ulysses spacecraft during its first pole to pole journey. We also give the temporal variation of the radius of these surfaces using measurements from spacecraft at 1 A...

Relative Realities, a media installation by Volkmar Klien, realized in co-operation with Thomas Grill investigates how movement and its perception relates across different media, modes and spaces. The installation’s sonic aspects are generated in real-time in accordance to the installation’s physical movement. This generative music engine is conceptualized and based on physical movement rather ...

Using a series of reflective case-studies, the role of the Foley artist is reconsidered alongside technological innovations in both digital soundmanipulation and physical computing. Through a series of theatrical productions and collaborations Challis and Dean have explored the sonic and dramatic possibilities created by the utilisation of digital technology in a live performance context. In th...

In the Internet world, the widespread use of graphical user interfaces (GUIs) increasingly bars visually handicapped people from accessing digital information. In this context our project aims at providing sight handicapped people with alternative access modalities to various types of GUIs and graphic intensive programs, in order for instance to facilitate usage of Web services. We describe in ...

The Drosophila Hedgehog protein and its vertebrate counterpart Sonic hedgehog are required for a wide variety of patterning events throughout development. Hedgehog proteins are secreted from cells and undergo autocatalytic cleavage and cholesterol modification to produce a mature signaling domain. This domain of Sonic hedgehog has recently been shown to acquire an N-terminal acyl group in cell ...

New-generation electromagnetic (EM) and sonic logging tools are capable of measuring multi-frequency multi-component data at multiple depths of investigation. This allows us to image the formation around the borehole by using an inversion method. A method is developed for directly obtaining porosity and fluid saturation distributions by simultaneously inverting borehole EM and sonic measurement...
