The Study of heat transfer augmentation in micro scale and electronic packaging systems are some of the paramount areas of the impending universe. In such systems the cooling of the heat sinks are generally achieved through the impingement of air jet. Assuming the air jet to be continues & incompressible fluid, the heat dissipation rate over the target surface seems to either uniform or well ch...

We show, apart from a correlation inequality for the 6-point function, that the critical or continuum liinit of (11'4)4 lattice field theory is trivial, if some deviations from the mean field theory law are present at the critical point, and if we impose a mild behavior of bare 4-point coupling constant as we approach the critical point. These results are derived from the bounds on the renormal...

We compute the homology of the integral manifolds of the restricted three-body problem | planar and spatial, unregularized and regularized. Holding the Jacobi constant xed de nes a three dimensional algebraic set in the planar case and a ve dimensional algebraic set in the spatial case (the integral manifolds). The singularities of the restricted problem due to collusions are removable which de...

The recent LEP data for gauge coupling constants constrain many grand unified models. In this paper, we study several possibilities for unification of gauge coupling constants. Without an intermediate scale, the minimal supersymmetric standard model with two Higgs doublets is the only possibility. For one intermediate scale, we present a few unification schemes without supersymmetry. One of the...

Westerly wind bursts (WWBs) in the equatorial Pacific occur during the development of most El Niño events and are believed to be a major factor in ENSO’s dynamics. Because of their short time scale, WWBs are normally considered part of a stochastic forcing of ENSO, completely external to the interannual ENSO variability. Recent observational studies, however, suggest that the occurrence and cha...

Microtubule assembly kinetics have been studied quantitatively under solution conditions supporting microtubule dynamic instability. Purified GTP-tubulin (Tu-GTP) and covalently cross-linked short microtubule seeds (EGS-seeds; Koshland et al. (1988) Nature 331, 499) were used with and without biotinylation. Under sub-critical concentration conditions ([Tu-GTP] < 5.3 microM), significant microtu...

In the first part (Sections 1 and 2) of this paper —starting from the Pauli current, in the ordinary tensorial language— we obtain the decomposition of the non-relativistic field velocity into two orthogonal parts: (i) the “classical” part, that is, the velocity ~ w = ~p/m of the centerof-mass (CM), and (ii) the so-called “quantum” part, that is, the velocity ~ V of the motion in the CM frame (...

We study quenched QCD at finite chemical potential, μI , for the third component of isospin and quenched two-colour QCD at finite chemical potential, μ, for quark number. In contrast to the quenched approximation to QCD at finite quark-number chemical potential, the quenched approximations to these theories behave similarly to the full theories. The reason is that these theories have real posit...

We calculate the broadband radio–X-ray spectra predicted by microblazar and microquasar models for Ultra-Luminous X-ray sources (ULXs), exploring the possibility that their dominant power-law component is produced by a relativistic jet, even at near-Eddington mass accretion rates. We do this by first constructing a generalized disk–jet theoretical framework in which some fraction of the total a...

Abstract We develop an efficient algorithm for evaluating divergent perturbation expansions of field theories in the bare coupling constant gB for which we possess a finite number L of expansion coefficients plus two more informations: The knowledge of the large-order behavior proportional to (−α)kk!kβgk B, with a known growth parameter α, and the knowledge of the approach to scaling being of t...
