This paper presents a novel broadband modulation method for digital underwater communications: Chirp Slope Keying (CSK). In its simplest form, the binary information modulates the slope of a linear chirp, with up-chirps representing ones and down-chirps representing zeros. Performance evaluation in the form of probability of error vs. SNR show that the system performs as expected for AWGN envir...
Recent studies suggest a role for the arachidonic acid-derived epoxyeicosatrienoic acids (EETs) in attenuating epileptic seizures. However, their effect on neurotransmission has never been investigated in detail. Here, we studied how 11,12- and 14,15 EET affect excitability and excitatory neurotransmission in mouse hippocampus. 11,12 EET (2 μM), but not 14,15 EET (2 μM), induced the opening of ...
Few data are available concerning single Ca channel properties in inner ear hair cells, and particularly none in vestibular type I hair cells. By using the cell-attached configuration of the patch-clamp technique in combination with the semicircular canal crista slice preparation, we determined the elementary properties of voltage-dependent Ca channels in chicken embryo type I and type II hair ...

Multipath signal propagation has long been viewed as an impairment to reliable communication in wireless channels. This paper shows that the presence of multipath greatly improves achievable data rate if the appropriate communication structure is employed. A compact model is developed for the multiple-input multiple-output (MIMO) dispersive spatially selective wireless communication channel. Th...
