To aid in evaluating spatial and spectral imaging abilities of any imaging spectroradiometer system, we developed a spectral intensity gradient standard based on the behavior of a birefringent wedge imaged between cross polarizers. By comparing calculated with observed images of the wedge, a chromatic scrambling kernel was measured to generally estimate chromatic aberrations in any spectral ima...

Xk-related protein (Xkr) 8, a protein carrying 10 transmembrane regions, is essential for scrambling phospholipids during apoptosis. Here, we found Xkr8 as a complex with basigin (BSG) or neuroplastin (NPTN), type I membrane proteins in the Ig superfamily. In BSG(-/-)NPTN(-/-) cells, Xkr8 localized intracellularly, and the apoptosis stimuli failed to expose phosphatidylserine, indicating that B...

— Aiming at the problem of blind estimation of Pseudo-random (PN) sequences in multi-user long scrambling code direct sequence spread spectrum (LSC-DSSS) signals, in this paper, we proposed a novel PN sequences estimation method based on Fast-ICA algorithm and third-order statistics. The received signal is firstly divided twice into segments and then the segments are transformed into several a...

As a first step in studying the application of the global positioning system (GPS) in a spatial audio communication system, an experimental platform was developed using commercial, off-the-shelf (COTS) GPS units: a Garmin Rino 120 (Rino) and a laptop. Software running on the laptop was developed to create a spatial-audio communication system based on GPS data and the two-way radio link on the R...

Minimalist Grammars were proposed recently as a model for the formal description of the natural-language syntax. This paper explores a nonlocal extension to this formalism that would make it possible to describe unbounded scrambling which is a discriptionally problematic syntactic phenomenon attested in many languages. It is shown that extending Minimalist Grammars with scrambling without short...

Kanum, a language of southern New Guinea, displays nonconfigurationality only for arguments marked with an overt structural case. After examining a variety of constraints on scrambling, in main and subordinate clauses, I argue that nonconfigurationality is a process of scrambling, rather than independent mapping from functional structure to constituency, and further is dependent on features ass...

In this paper, we address the problem of scrambling regions of interest in a video sequence. We target applications such as video surveillance preserving privacy, anonymous video communications, or TV news safeguarding the anonymity of a source. We propose an efficient solution based on transform-domain scrambling. More specifically, the sign of selected transform coefficients is flipped during...

In this paper we propose an overview of a project aiming at building an audio-visual laughter synthesis system. The same approach is followed for acoustic and visual synthesis. First a database has been built to have synchronous audio and 3D visual landmarks tracking data. Then this data has been used to build HMM models of acoustic laughter and visual laughter separately. Visual laughter model...

We investigated the influence of peptide size on the apparent loss of sequence during collision-induced dissociation (CID) of b ions using a group of peptides containing from between 4 and 10 residues. Although scrambling of sequence for b3+ generated from tetrapeptides is minimal, significant formation of nondirect sequence ions (i.e., ions for which scrambling has apparently occurred) was obs...

A real-time virtual audio reality model has been created. The system includes model-based sound synthesizers, geometric room acoustics modeling, binaural auralization for headphone or loudspeaker listening, and high-quality animation. The design goals of the overall project have been to create a virtual musical event that is as authentic as possible both in terms of audio and visual quality. No...
