Compression efficiency is mainly driven by redundancy of the overcomplete set of functions chosen for the signal decomposition. In Matching Pursuit algorithms for example, the redundancy of the dictionary influences the convergence of the residual energy. ...
The security of several elliptic curve cryptosystems is based on the difficulty to compute the discrete logarithm problem. The motivation of using elliptic curves in cryptography is that there is no known sub-exponential algorithm which solves the Elliptic ...
PPAR-gamma/RXR heterodimers play a key regulatory role in murine placental development. We report here that PPAR-gamma and RXR-alpha are highly expressed in cultured primary extravillous cytotrophoblasts (EVCT) isolated from human first-trimester placenta. ...
We consider the problem of interpolating a signal using a linear combination of shifted versions of a compactly-supported basis function φ(x). We first give the expression of the φ's that have minimal support for a given accuracy (also known as "approximat ...
The retinoblastoma protein (RB) has previously been shown to facilitate adipocyte differentiation by inducing cell cycle arrest and enhancing the transactivation by the adipogenic CCAAT/enhancer binding proteins (C/EBP). We show here that the peroxisome pr ...
NF-kappaB/Rel transcription factors and IkappaB kinases (IKK) are essential for inflammation and immune responses, but also for bone-morphogenesis, skin proliferation and differentiation. Determining their other functions has previously been impossible, ow ...
Bioinformatics encompasses a wide range of approaches, techniques and philosophies, and the chem. engineer has an opportunity to make a significant impact both by working in areas with biochem. engineering and by working in collaboration with colleagues fr ...
The ligand-dependent nuclear receptors PPARgamma and RXRalpha/beta were recently determined to be essential for murine placental development and trophoblast differentiation. In the current study we examined the expression and role of the PPARgamma/RXRalpha ...
A method is proposed that allows each individual party to an elliptic curve cryptosystem to quickly determine its own unique pair of finite field and Weierstrass equation, in such a way that the resulting pair provides adequate security. Although the choic ...
Aquaporins are transmembrane water channel proteins, which play important functions in the osmoregulation and water balance of microorganisms, plants, and animal tissues. All aquaporins studied to date are thought to be tetrameric assemblies of four subuni ...
