Abstract
We implement full polarization tomography on photon correlations in a spinor exciton-polariton condensate. Our measurements reveal condensate pseudospin mean-field dynamics spanning from stochastic switching between linear polarization components, limit cycles, and stable fixed points, and their intrinsic relation to the condensate photon statistics. We optically harness the cavity birefringence, polariton interactions, and the optical orientation of an incoherent exciton reservoir to engineer photon statistics with precise control. Our results demonstrate a smooth transition from a highly coherent to a super-thermal state of the condensate polarization components.

Abstract
A molecular approach was developed to identify drug-resistant strains of Mycobacterium tuberculosis by means of biochips with oligonucleotides immobilised in polyacrylamide gel pads. The technique was based on multiplex PCR, followed by hybridisation on an oligonucleotide microarray, and detected > 95% of rifampicin-resistant and c. 80% of isoniazid-resistant M. tuberculosis isolates within 12 h. In total, 220 drug-resistant isolates and 131 clinical samples were tested using biochips. The sensitivity and specificity of the developed method were comparable with those of standard bacteriological testing of M. tuberculosis drug resistance.

Abstract
Three new molecular approaches were developed to identify drug-resistant strains of Mycobacterium tuberculosis using biochips with oligonucleotides immobilized in polyacrylamide gel pads. These approaches are significantly faster than traditional bacteriological methods. All three approaches-hybridization, PCR, and ligase detection reaction--were designed to analyze an 81-bp fragment of the gene rpoB encoding the beta-subunit of RNA polymerase, where most known mutations of rifampin resistance are located. The call set for hybridization analysis consisted of 42 immobilized oligonucleotides and enabled us to identify 30 mutant variants of the rpoB gene within 24 h. These variants are found in 95% of all mutants whose rifampin resistance is caused by mutations in the 81-bp fragment. Using the second approach, allele-specific on-chip PCR, it was possible to directly identify mutations in clinical samples within 1.5 h. The third approach, on-chip ligase detection reaction, was sensitive enough to reveal rifampin-resistant strains in a model mixture containing 1% of resistant and 99% of susceptible bacteria. This level of sensitivity is comparable to that from the determination of M. tuberculosis drug resistance by using standard bacteriological tests.
