Transbilayer lipid asymmetry in platelets and other cells is maintained by an aminophospholipid translocase, an active transporter pumping aminophospholipids phosphatidylserine (PS) and phosphatidylethanolamine from the outer to the inner leaflet of the plasma membrane. Under particular conditions, phospholipid asymmetry is disrupted by a “scrambling” process, in which the phospholipids become ...

Recreating a natural listening experience is the aim of spatial audio reproduction system. Despite the increasing popularity of object-based audio, majority of the legacy audio contents are in channel-based format, which is dependent on the desired playback system. Considering the diversity of today’s playback systems, the quality of reproduced sound scenes degrades significantly when mismatche...

This paper presents a prototype of a 3D audio recording system named AudioSense which uses Wireless Acoustic Sensors to capture spatial audio. The sound is recorded in real-time by microphones embedded in each sensor device and streamed to a Processing Unit for 3D audio compression. One of the key problems in systems which stream audio data is end-to-end latency. This paper is focused on analyz...

In this study, we present the SpeechFind system, an experimental on-line spoken document retrieval system for historical audio archives. As part of an on-going U.S. NSF Digital Library Initiative project, entitled the National Gallery of the Spoken Word (NGSW), SpeechFind is intended to serve as an audio index and search engine for spoken word collections spanning the 20th century with as much ...

This study characterizes the descriptive and theoretical properties of scrambling in Central Kurdish. Scrambling denotes a phenomenon or process by which constituents clause are displaced from their original unmarked positions placed other sentence. Following tenets concepts as currently assumed work within framework Minimalist Program, answers questions that related to types may undergo langua...

The Structured Audio Information Retrieval System (STAIRS) project targets environments where workers need access to information, but cannot use traditional hands-and-eyes devices, such as a PDA. The information to be accessed is stored in an information base, either as pre-recorded audio or as text to be run through a text-to-speech engine. Given the inherent limitations of the simple audio in...

This paper presents overview of an online audio indexing system, which creates a searchable index of speech content embedded in digitized audio files. This system is based on our recently proposed offline audio segmentation techniques. As the data arrives continuously, the system first finds boundaries of the acoustically homogenous segments. Next, each of these segments is classified as speech...

T h e audio quality, robustness and complexity issues of a novel mobile digital audio broadcast (DAB) scheme a re addressed. T h e audio codec is based on a combination of subband coding (SBC) and mult ipulse excited linear predictive coding ( M P L P C ) , where the bi t allocation is dynamically adapted according t o both the signal power in different subbands and a perceptual hearing model. ...

This paper provides a look at how modulated broad-band noises modulate the thalamic response evoked by brief probe sounds in the awake animal. We demonstrate that noise not only attenuates the response to probe sounds (masking) but also changes the temporal response pattern (scrambling). Two brief probe sounds, a Gaussian noise burst and a brief sinusoidal tone, were presented in silence and in...

Direct-sequence code-division multiple-access (DS-CDMA) signals are often regarded as a result of the multiplication of the data bits by a spreading sequence, clocked at a higher rate than the data sequence (where the factor of the rates is the spreading factor), cf. figure 1 a. A conceptually different, but equivalent, description is that the symbol rate is raised by up-sampling (repetition en...
