Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus… (More)

We analyse derivative securities whose value is not a deterministic function of an underlying which means presence of a basis risk at any time. The key object of our analysis is conditional probability distribution at a given underlying value and moment of time. We consider time evolution of this probability distribution for an arbitrary hedging strategy… (More)

Fifteen fluorescent pseudomonads, isolated from the rhizosphere of agricultural plants, were similar in both their phenotypic properties and the chemical nature of produced pigments, to the previously described Pseudomonas fluorescens var. pseudoiodinum. DNA-DNA hybridisation data showed their genetic similarity (but not identity) to different biovars of P.… (More)

This paper compares theory and experiment for the kinetics of time-dependent sedimentation. We discuss non-interacting suspensions and colloids which may exhibit behavior similar to the one-dimensional motion of compressible gas. The velocity of sedimentation (or creaming) depends upon the volume fraction of the constituting particles and leads to… (More)

The kinetic energy distribution function satisfying the Boltzmann equation is studied analytically and numerically for a system of inelastic hard spheres in the case of binary collisions. Analytically, this function is shown to have a similarity form in the simple cases of uniform or steady-state ows. This determines the region of validity of hydrodynamic… (More)

IR and electron spectra of an uracil derivative (antitumor antibiotic reumycin) were studied by low temperature spectroscopy. The experimental data corresponded to the quantum chemistry calculations of electron transmission. On the basis of the spectra interpretation the molecular structure of the reumycin isolated molecules was suggested. pKa of reumycin… (More)

We analize the properties of dense granular systems by assuming a hydrodynamical description , based on conservation laws for the particle number density and linear momentum. We combine analytical methods and experimental and numerical results obtained by ensemble-averaging of data on creep during compaction and molecular dynamics simulations of convective… (More)

Hedging a derivative security with non-risk-neutral number of shares leads to portfolio profit or loss. Unlike in the Black-Scholes world, the net present value of all future cash flows till maturity is no longer deterministic, and basis risk may be present at any time. The key object of our analysis is probability distribution of future P&L conditioned on… (More)
