BCS Instability and Finite Temperature Corrections to Tachyon Mass in Intersecting D1-Branes [PDF]

open access: yes, 2014
A holographic description of BCS superconductivity is given in arxiv:1104.2843. This model was constructed by insertion of a pair of D8-branes on a D4-background.

Cloning and amplified expression in Streptomyces lividans of the gene encoding the extracellular β-lactamase of Actinomadura R39 [PDF]

open access: yesBiochemical Journal, 1989
By using the promoter-probe plasmid pIJ424, genomic DNA fragments of Actinomadura R39 were shown to have promoter activity in Streptomyces lividans. The same 100-200-copy-number plasmid was used to clone in S. lividans TK24, the gene that encodes the Actinomadura R39 beta-lactamase. Gene cloning resulted in an amplified expression of the beta-lactamase

Over a Million Student Tenants in Poland. Analysis of Preferences

open access: yesReal Estate Management and Valuation, 2018
Students as property tenants are an underestimated and understudied aspect of the market. To date, there has been a widely held opinion that student decisions in the property market and their scope are mostly limited to the area of academic centres.

Structural Breaks and Explosive Behavior in the Long-Run: The Case of Australian Real House Prices, 1870–2020

open access: yesEconomics: Journal Articles, 2021
In this article, we use tests of explosive behavior in real house prices with annual data for the case of Australia for the period 1870–2020. The main contribution of this paper is the use of very long time series. It is important to use longer span data

M(atrix) String Theory on K3

open access: yes, 1997
We conjecture that M-theory compactified on an ALE space (or K3) is described by 0-branes moving on the ALE space. We give evidence for this by showing that if we compactify another circle, we recover string theory on the ALE space.

dd -Carboxypeptidase-Transpeptidase and Killing Site of β-Lactam Antibiotics in Streptomyces Strains R39, R61, and K11 [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1973
Additional evidence is given that in Streptomyces strains R39, R61, and K11 the same enzyme performs dd -carboxypeptidase and transpeptidase activities and that this enzyme is the killing site of β-lactam antibiotics. With strain R61, it was found that the exocellular enzyme has a sensitivity

Accessibility of Real Estate by Transportation as a Determinant of the Development of Suburban Real Estate Markets – Case Study

open access: yesReal Estate Management and Valuation, 2016
The aim of this article is to show the accessibility of real estate by transportation as a factor that significantly determines the decision to acquire it. Direct access to a public road, or access to an internal road that provides communication with the

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

Interaction of β-iodopenicillanate with the β-lactamases of Streptomyces albus G and Actinomadura R39 [PDF]

open access: yesBiochemical Journal, 1982
The beta-lactamases of Streptomyces albus G and Actinomadura R39 are inactivated by beta-iodopenicillanate. However, in contrast with the beta-lactamase I from Bacillus cereus, they also efficiently catalyse the hydrolysis of the inactivator; with the S. albus G enzyme, kcat.

Studies on the primary structures of the exocellular d-alanyl-d-alanine peptidases of Streptomyces strain R61 and Actinomadura strain R39 [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Protein Structure, 1981
The Mr 37 000 D-alanyl-D-alanine peptidase excreted by Streptomyces R61 and the Mr 53 000 D-alanyl-D-alanine peptidase excreted by Actinomadura R39 are both characterized by a very uneven distribution of the basic (Arg + Lys) amino acid residues. Trypsin degradation of the heat-denatured enzymes generates (1) thirteen soluble peptides which contain ...
