The multiresolution analysis (MRA) strategy for homogenization consists of two algorithms ; a procedure for extracting the eeective equation for the average or for the coarse scale behavior of the solution to a diierential equation (the reduction process) and a method for building a simpler equation whose solution has the same coarse behavior as the(More)
The precursor (pmAspAT) and mature (mAspAT) forms of mitochondrial aspartate aminotransferase interact with hsp70 very early during translation when synthesized in either rabbit reticulocyte lysate or wheat germ extract (Lain, B., Iriarte, A., and Martinez-Carrion. (1994) J. Biol. Chem. 269, 15588-15596). The nature of the structural elements responsible(More)
alpha-Bungarotoxin (alpha-Bgt) is a potent postsynaptic neurotoxin which blocks neurotransmission by binding very tightly to the acetylcholine-receptor (AcChR) protein. We have previously shown (P. Calvo-Fernandez, and M. Martinez-Carrion (1981) Arch. Biochem. Biophys. 208, 154-159) that alpha-Bgt free in its native solution conformation incorporates 12(More)
In order to use persistence diagrams as a true statistical tool, it would be very useful to have a good notion of mean and variance for a set of diagrams. In [21], Mileyko and his collaborators made the first study of the properties of the Fréchet mean in (D p , W p), the space of persistence diagrams equipped with the p-th Wasserstein metric. In(More)
In order to use persistence diagrams as a true statistical tool, it would be very useful to have a good notion of mean and variance for a set of diagrams. In [21], Mileyko and his collaborators made the first study of the properties of the Fréchet mean in (Dp, Wp), the space of persistence diagrams equipped with the p-th Wasserstein metric. In particular,(More)
This paper uses high-frequency S&P 500 index futures data and data on the VIX index to provide an arbitrage-free explanation of the variance risk premium and its dynamics. Using the high-frequency data only, I select a semiparametric two-factor stochastic volatility model, containing jumps in the price and the stochastic variance. For this model I derive(More)
A 2.4 kilobase cDNA for rat mitochondrial aspartate aminotransferase (E.C. 2.6.1.1.) was isolated and sequenced. The predicted presequence is 93% homologous to the presequences of the enzyme from pig and mouse. The predicted amino acid sequence of the mature enzyme differs from that determined directly by amino acid sequencing (Huynh, Q.K., Sakakibara, R.,(More)
