A PCR-based assay that can simultaneously detect and differentiate five different types of nosocomial bacterial pathogens was developed. Six pairs of selected primers targeting femA (132 bp) and mecA (310 bp) of methicillin-resistant Staphylococcus aureus, gltA (722 bp) of Acinetobacter baumannii, phoA (903 bp) of Escherichia coli, mdh (364 bp) of Klebsiella pneumoniae and oprL (504 bp) of Pseu...

SME Gravity Sector

The Standard-Model Extension (SME) is defined as the general effective field theory (EFT) that incorporates Lorentz violation. In flat Minkwoski spacetime, the SME has the following features: ⇒ it is defined in terms of an observer-scalar Lagrangian L ⇒ it includes dynamical matter fields φ, ψ, A, . . . ⇒ it includes fixed background tensors aμ, bμ, cμν , . . . that break Lorentz symmetry ⇒ it ...

Exactly Soluble Sector of Quantum Gravity

Cartan’s spacetime reformulation of the Newtonian theory of gravity is a generallycovariant Galilean-relativistic limit-form of Einstein’s theory of gravity known as the Newton-Cartan theory. According to this theory, space is flat, time is absolute with instantaneous causal influences, and the degenerate ‘metric’ structure of spacetime remains fixed with two mutually orthogonal non-dynamical m...

+1 Sector of 3+1 Gravity

The rank–1 sector of classical Ashtekar gravity is considered, motivated by the degeneracy of the metric along the Wilson lines in quantum loop states. It is found that the lines behave like 1+1 dimensional spacetimes with a pair of massless complex fields propagating along them. The inclusion of matter and extension to supergravity are also considered. In Ashtekar’s Hamiltonian formulation of ...

Conformal Sector in D = 6 Quantum Gravity

We discuss the conformal factor dynamics in D = 6. Accepting the proposal that higher-derivative dimensionless terms in the anomaly-induced effective action may be dropped, we obtain a superrenormalizable (like in D = 4) effective theory for the conformal factor. The one-loop analysis of this theory gives the anomalous scaling dimension for the conformal factor and provides a natural mechanism ...
