Frame erasure (FE) robustness is an important quality measure for voice over IP networks (VoIP). Recovery of the erased frames from the received information is crucial to realize this robustness. We allow the lost frames to be recovered from both the “previous” and “next” good frames. We first give quantitative distortion comparisons between predictive and interpolative frame recovery. Then we ...

Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This paper deals with DG for minimizing active power loss and D-statcom for reactive power loss minimization is considered. The proper siting of DG and D-statcom is a recently developed combination with the aim of reducing line loss in a radial distribution system. Loss Sensitivity Factor (LSF) ...

The current research examines whether trait anxiety is associated with negative interpretation bias when resolving valence ambiguity of surprised faces. To further isolate the neuro-cognitive mechanism, we presented angry, happy, and surprised faces at broad spatial frequency (BSF), high spatial frequency (HSF), and low spatial frequency (LSF) and asked participants to determine the valence of ...

Spatial frequencies in an image influence visual analysis across a distributed, hierarchically organized brain network. Low spatial frequency (LSF) information may rapidly reach high-order areas to allow an initial coarse parsing of the visual scene, which could then be "retroinjected" through feedback into lower level visual areas to guide finer analysis on the basis of high spatial frequency ...

Laser speckle flowmetry (LSF) was initially developed to measure blood flow in the retina. More recently, its primary application has been to image baseline blood flow and activity-dependent changes in blood flow in the brain. We now describe experiments in the rat retina in which LSF was used in conjunction with confocal microscopy to monitor light-evoked changes in blood flow in retinal vesse...

In this paper, the use of optimal KarhunenLoeve (KL) transform for quantization of speech line spectrum frequency (LSF) coefficients is studied. Both scalar quantizer (SQ) and vector quantizer (VQ) schemes are developed to encode efficiently the transform parameters after operating one or two-dimensional KL transform. Furthermore, the SQ schemes are also combined with entropy coding by using Hu...

5-FU is a common first-line chemotherapeutic drug for the treatment of hepatocellular carcinoma. However the development of acquired resistance to 5-FU confines its clinical usages. Although this phenomenon has been the subject of intense investigation, the exact mechanism of acquired resistance to 5-FU remains elusive. Here, we report that over-expression of GRP78 contributes to acquired resis...

Chuckwalla lizards (genus Sauromalus) may accumulate substantial quantities of body fluid in extracoelomic, lateral abdominal spaces called accessory lymph sacs. The lymph sac fluid (LSF) of S. hispidus is similar to that of serum in Na+, K+ and Cl- concentrations, but the total protein content (3.58 +/- 0.20 g dl-1) is only half that measured in serum (7.05 +/- 0.26 g dl-1). These analyses con...

OBJECTIVES The only locus unequivocally associated with late onset Alzheimer's disease (AD) risk is APOE. However, this locus accounts for less than half the genetic variance. A recent study suggested that the A allele of the 3'UTR biallelic polymorphism in the LBP-1c/CP2/LSF gene was associated with reduced AD risk. Samples were diagnosed predominantly by clinical rather than pathological crit...

Our researches focus on Sign Language (SL) gestures, which can be manual or non-manual (like facial expressions). This abstract presents the study we conduct in the field of French SL (LSF) processing. We intend to propose a coarticulation model of signs of LSF, thus we need accurate analysis of both isolated and in utterance signs. We follow a several step methodology: video corpus creation, a...
