Secure spread spectrum watermarking for multimedia
- IEEE TRANSACTIONS ON IMAGE PROCESSING
, 1997
"... This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gauss ..."

.i.d.) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the perceptually most significant spectral components of the data. We argue that insertion of a watermark under this regime makes the watermark robust to signal processing operations (such as lossy compression
COSMOLOGICAL PARAMETERS: FASHION AND FACTS
, 2003
"... We are at a specific period of modern cosmology, during which the large increase of the amount of data relevant to cosmology, as well as their increasing accuracy, leads to the idea that the determination of cosmological parameters has been achieved with a rather good precision, may be of the order ..."

However, the necessary introduction of a non zero cosmological constant is an extraordinary new mystery for physics, or more exactly the come back of one of the ghost of modern physics since its introduction by Einstein. Here, I would like to emphasize
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

TETANUS TOXOID IN AN MHC-RESTRICTED FASHION
"... Although the TCR-y/S complex contains relatively few germline V gene segments (1, 2), the TCR-y diversity is increased by N nucleotide incorporation at the VJ junction (1), and TCR-Sjunctional diversity is high, with the use of at least two tandemly arranged Db elements and extensive N nucleotide in ..."

Because adult TCRy/S shows the most extensive dichotomy with respect to the spectrum of V region diversity compared with junctional diversity, Davis and Bjorkman (3) have suggested that the ligand for y/S heterodimer will consist ofa peptide fragment of antigen in association with an MHC-like
Inhibition of apoptosis and prolongation of neutrophil functional longevity by inflammatory mediators
- J. Leukoc. Biol
, 1993
"... Abstract: Neutrophil apoptosis leads to macrophage ingestion of intact senescent neutrophils. This may represent a neutrophil removal mechanism that is important both in the control of inflammatory tissue injury and for the normal resolution processes of inflammation. Because apoptosis is likely to ..."

Virtual Fashion- Tracking and Analyzing Cultural Dispersion on the World Wide Web
"... In the real world, people clothe themselves in garments whose cut and design encodes information about their social identity. This encoding changes temporally as the design spreads throughout a population: this is the basis of "fashion." A similar sense of fashion has emerged on the World ..."

"... Abstract In this article the idenfication of a fashion product, its variability and the analyses of fashion as an industrial design will be discussed within the framework of fashion product marketing. The process of product creation is closely related to the economic, sociological and psychological ..."

Fashion is the slave of imagination and just like in nostalgy movement it is inspired by the past as well
Indicators for Social and Economic Coping Capacity - Moving Toward a Working Definition of Adaptive Capacity”, Wesleyan-CMU Working Paper.

The stock of human capital (Determinant 4) could be a local characteristic, as well, but its local manifestation would likely be driven in large measure by macro-scale forces such as national support of local education.

Jammer Excision in Spread Spectrum Communications via Discrete Evolutionary Transform
"... In this paper, we propose time-frequency jammer exci-sion techniques for direct sequence spread spectrum com-munications. One method is based on the estimation of the instantaneous frequency (IF) of each of the chirp jam-mer components using a combination of the discrete evolu-tionary and the Hough ..."
