Dense analytic subspaces in fractalL2-spaces

- P. Jorgensen, Steen Pedersen
- Mathematics
- 30 September 1997

We show that for certain self-similar measures μ with support in the interval 0≤x≤1, the analytic functions {ei2πnx:n=0,1,2, …} contain an orthonormal basis inL2 (μ). Moreover, we identify subsetsP ⊂… Expand

Limiting factors in Escherichia coli fed-batch production of recombinant proteins.

- A. Sandén, Ingela Prytz, +15 authors G. Larsson
- Biology, Medicine
- Biotechnology and bioengineering
- 20 January 2003

Fed-batch production of recombinant beta-galactosidase in E. coli was studied with respect to the specific growth rate at induction. The cultivations were designed to induce protein production by… Expand

Molecular crowding limits translation and cell growth

- S. Klumpp, M. Scott, Steen Pedersen, T. Hwa
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 30 September 2013

Significance In rapidly growing bacteria, one-third of the proteins are ribosomal proteins and another one-sixth are ternary complexes (TCs) that bring amino acids to the ribosomes, making TCs the… Expand

Pseudouridylation of helix 69 of 23S rRNA is necessary for an effective translation termination

- M. Ejby, M. Sørensen, Steen Pedersen
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 4 December 2007

Escherichia coli strains with inactivated rluD genes were previously found to lack the conserved pseudouridines in helix 69 of 23S ribosomal RNA and to grow slowly. A suppressor mutant was isolated… Expand

Introduction to Continuity

- Steen Pedersen
- Mathematics
- 2015

In this chapter the algebra of continuous functions is established. A function that is continuous at each irrational number and discontinuous at each rational number is constructed. This function is… Expand

Patterns of protein synthesis in E. coli: a catalog of the amount of 140 individual proteins at different growth rates

- Steen Pedersen, P. L. Bloch, S. Reeh, F. C. Neidhardt
- Biology, Medicine
- Cell
- 1 May 1978

The amount of 140 individual proteins of E. coli B/r was measured during balanced growth in five different media. The abundance of each protein was determined from its absolute amount in… Expand

Spectral pairs in cartesian coordinates

- P. Jorgensen, Steen Pedersen
- Mathematics
- 1 July 1999

AbstractLet Ω ⊂ℝd have finite positive Lebesgue measure, and let
$$\mathcal{L}^2$$
(Ω) be the corresponding Hilbert space of
$$\mathcal{L}^2$$
-functions on Ω. We shall consider the exponential… Expand

Spectral Sets Whose Spectrum Is a Lattice with a Base

- Steen Pedersen
- Mathematics
- 1 November 1996

Abstract Let L be a finite subset of Euclidean d -dimensional space R d and let S be a lattice in R d such that { l − l ′ : l , l ′∈ L }∩ S ={0}. A classification of all Lebesgue measurable subsets… Expand

The functional half-life of an mRNA depends on the ribosome spacing in an early coding region.

- M. Pedersen, S. Nissen, N. Mitarai, Sine Lo Svenningsen, K. Sneppen, Steen Pedersen
- Biology, Medicine
- Journal of molecular biology
- 18 March 2011

Bacterial mRNAs are translated by closely spaced ribosomes and degraded from the 5'-end, with half-lives of around 2 min at 37 °C in most cases. Ribosome-free or "naked" mRNA is known to be readily… Expand

Spectral transition parameters for a class of Jacobi matrices

- J. Dombrowski, Steen Pedersen
- Mathematics
- 2002

This paper initially considers a class of unbounded Jacobi matrices dened by an increasing sequence of repeated weights. Spectral parameters are then introduced in various ways to allow the authors… Expand
