space is not σ-finite. p. 13: add after I.2.6.16: I.2.6.17. If X is a compact subset of C not containing 0, and k ∈ N, there is in general no bound on the norm of T −1 as T ranges over all operators with ‖T ‖ ≤ k and σ(T) ⊆ X. For example, let Sn ∈ L(l 2) be the truncated shift: Sn(α1, α2,...) = (0

Generating Hard Instances of Lattice Problems (Extended Abstract)

by M. Ajtai - In Proceedings of the Twenty-Eighth Annual ACM Symposium on the Theory of Computing , 1996

We give a random class of lattices in Z n so that, if there is a probabilistic polynomial time algorithm which finds a short vector in a random lattice with a probability of at least 1 2 then there is also a probabilistic polynomial time algorithm which solves the following three lattice probl ..."

Peroxisome proliferatoractivated receptor gamma interacts with CIITA/RFX5 complex to repress type I collagen gene expression

by Feng Xu, Jian Li, Wei Ni, Yi-wen Shen, Xiao-ping Zhang - J Biol Chem
"... Peroxisome proliferator-activated receptor-c (PPAR-c) has recently emerged as potential therapeutic agents for cerebral ischemia-reperfusion (I/R) injury because of anti-neuronal apoptotic actions. However, whether PPAR-c activation mediates neuronal autophagy in such conditions remains unclear. The ..."

. Therefore, in this study, we investigated the role of PPAR-c agonist 15-PGJ2 on neuronal autophagy induced by I/R. The expression of autophagic-related protein in ischemic cortex such as LC3-II, Beclin 1, cathepsin-B and LAMP1 increased significantly after cerebral I/R injury. Furthermore, increased

An elliptic collocation-finite element method with interior penalties

The integral orthogonalities are motivated by the interior penalty L2-Galerkin procedure of Douglas and Dupont. 1. Introfluction. Continuous L 2 and discontinuousH-1 f ..."

Adaptive Discontinuous Galerkin Finite Element Methods for Compressible Fluid Flows

by Paul Houston, Ralf Hartmann, Endre Süli, Endre Siili - SIAM J. Sci. Comput
"... this paper is to discuss the a posteriori error analysis and adaptive mesh design for discontinuous Galerkin finite element approximations to systems of conservation laws. In Section 2, we introduce the model problem and formulate its discontinuous Galerkin finite element approximation. Section 3 is ..."
