The hierarchy problem and new dimensions at a millimeter
, 2008
"... We propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor. In this framework, the gravitational and gauge interactions become united at the weak scale, which we take as the only fundamental short distance scale in nature. The observed wea ..."

.freely propagate in the new dimensions, at sub-weak energies the Standard Model SM fields must be localized to a 4-dimensional manifold of weak scale ‘‘thickness’ ’ in the extra dimensions. This picture leads to a number of striking signals for accelerator and laboratory experiments. For the case of ns2 new
Simulated climatology of a general circulation model with a hydrological cycle
- Mon. Wea. Rev
, 1965
"... The thermal and dynamical structure of the tropical atmosphere which emerged from the numerical integration of our general circulation model with a simple hydrologic cycle is analyzed in detail. According to the results of our analysis, the lapse rate of zonal mean temperature in the model Tropics i ..."

The flow field in the model Tropics also displays interesting features. For example, a zone of strong convergence and a belt of heavy
D-branes and short distances in string theory
"... We study the behavior of D-branes at distances far shorter than the string length scale ls. We argue that short-distance phenomena are described by the IR behavior of the D-brane world-volume quantum theory. This description is valid until the brane motion becomes relativistic. At weak string coupli ..."

Two-dimensional Keller-Segel model: Optimal critical mass and qualitative properties of the solutions
- J. DIFF. EQNS
, 2006
"... The Keller-Segel system describes the collective motion of cells which are attracted by a chemical substance and are able to emit it. In its simplest form it is a conservative drift-diffusion equation for the cell density coupled to an elliptic equation for the chemoattractant concentration. It is k ..."

-up in finite time in the whole euclidean space. Using hypercontractivity methods, we establish regularity results which allow us to prove an inequality relating the free energy and its time derivative. For a solution with sub-critical mass, this allows us to give for large times an “intermediate asymptotics
Seasonal eddy field modulation of the North Pacific Subtropical Countercurrent: TOPEX/Poseidon observations and theory
- J. Phys. Oceanogr
, 1999
"... Altimetry data from the first 5-yr TOPEX/Poseidon mission (October 1992–December 1997) are analyzed focusing on the North Pacific Subtropical Countercurrent (STCC) near the center of the Pacific’s western sub-tropical gyre. The multiyear altimetry data reveal that the eastward-flowing STCC is a high ..."

Methodology for energy management in industries
"... Abstract:- Energy is defined as the ability or capacity to do work. Energy can be found in number of different forms. It can be chemical energy, electrical energy, heat (thermal energy), light (radiant energy), mechanical energy, and nuclear energy. There has been an enormous increase in the demand ..."

The five most energy intensive industrial sub sectors including iron and steel, petroleum refining, cement
Dark Energy: The Observational Challenge
, 2005
"... Nearly all proposed tests for the nature of dark energy measure some combination of four fundamental observables: the Hubble parameter H(z), the distance-redshift relation d(z), the age-redshift relation t(z), or the linear growth factor D1(z). I discuss the sensitivity of these observables to the v ..."

Constraints on Gauss-Bonnet gravity in dark energy cosmologies
"... Abstract. Models with a scalar field coupled to the Gauss-Bonnet Lagrangian appear naturally from Kaluza-Klein compactifications of pure higher-dimensional gravity. We study linear, cosmological perturbations in the limits of weak coupling and slow-roll, and derive simple expressions for the main ob ..."

Using present observational data, and assuming slow-roll for the dark energy field, we find that the fraction of energy density associated with the coupled
