Effects of cell density, symbiotic plasmid and mutation (by transposon mutagenesis) on the expression of rhi genes in Rhizobium leguminosarum biovar viciae were studied. Strains of the bacterium bearing and lacking regulatory gene rhiR were grown to late exponential phase and assayed for the production of rhi genes inducer. R. leguminosarum biovar viciae was specific for the synthesis of the rh...

We study the thermodynamics of U(N) N = 4 Super Yang-Mills (SYM) on R × S3 with non-zero chemical potentials for the SU(4) R-symmetry. We find that when we are near a point with zero temperature and critical chemical potential, N = 4 SYM on R × S3 reduces to a quantum mechanical theory. We identify three such critical regions giving rise to three different quantum mechanical theories. Two of th...

Molecular fragmentation into three products poses an analytical challenge to theory and experiment alike. We used translational spectroscopy and high-level ab initio calculations to explore the highly debated three-body dissociation of sym-triazine to three hydrogen cyanide molecules. Dissociation was induced by charge exchange between the sym-triazine radical cation and cesium. Calculated stat...

BACKGROUND In microarray data analysis, hierarchical clustering (HC) is often used to group samples or genes according to their gene expression profiles to study their associations. In a typical HC, nested clustering structures can be quickly identified in a tree. The relationship between objects is lost, however, because clusters rather than individual objects are compared. This results in a t...

We test the spectrum of string theory on AdS5 × S5 derived in hep-th/0305052 against that of single-trace gauge invariant operators in free N = 4 super Yang-Mills theory. Masses of string excitations at critical tension are derived by extrapolating plane-wave frequencies at gYM = 0 down to finite J . On the SYM side, we present a systematic description of the spectrum of single-trace operators ...

Symmetry is a pervasive phenomenon presenting itself in all forms and scales in natural and manmade environments and its detection plays an essential role at all levels of human as well as machine perception. The recent resurging interest in computational symmetry for computer vision and computer graphics applications has motivated us to conduct an US NSF funded symmetry detection algorithm com...

Article history: Received 18 June 2013 Accepted after revision 26 November 2013 Available online 20 December 2013 Presented by Philippe G. Ciarlet We present some Poincaré-type inequalities for quadratic matrix fields with applications e.g. in gradient plasticity or fluid dynamics. In particular, applications to the pseudostress– velocity formulation of the stationary Stokes problem and to infi...

Abstract Let $f$ f be a cuspidal Hecke eigenform without complex multiplication. We prove the automorphy of symmetric power lifting $\operatorname{Sym}^{n} f$ Sym n for every $n \geq 1$ ≥ 1 .

We address the issue of correspondence between classical supergravity and quantum super Yang-Mills (or Matrix theory) expressions for the long-distance, lowvelocity interaction potentials between 0-branes and bound states of branes. The leading-order potentials are reproduced by the F 4 terms in the 1-loop SYM effective action. Using self-consistency considerations, we determine a universal com...
