Temperature contrasts between warm tropics and cool high latitudes depends on how efficiently heat is transported by the atmosphere (and oceans) from the tropics. This heat transport is generally assumed to be proportional to atmospheric pressure, but we show with a simple model that this prediction fails by orders of magnitude for Mars and Titan. However, a basic principle, previously postulat...

The conventional value chain that has underpinned utilities for so long is today undergoing disruptive changes. One way flows of energy and digital information are evolving into multi-directional flows of real time data spanning various aspects of operations. A major driver of this dramatic shift is the increasing penetration of consumer centric technologies, such as distributed generation and ...

The radiative efficiencies of accretion flows become significantly lower than that of standard thin disks, if they are accreting at rates lower than a critical accretion rate ṁcrit. The transition of a standard thin disk to a radiatively inefficient accretion flow (RIAF) is expected to occur, while ṁ ∼ ṁcrit (ṁ = Ṁ/ṀEdd). We simulate the distributions of Eddington ratio λL B λ/LEdd for active g...

We demonstrate that nucleosynthesis in rapid, high-entropy expansions of proton-rich matter from high temperature and density can result in a wider variety of abundance patterns than heretofore appreciated. In particular, such expansions can produce iron-group nuclides, p-process nuclei, or even heavy, neutron-rich isotopes. Such diversity arises because the nucleosynthesis enters a little expl...

Industries which pump sludges are under continuous pressure to decrease water content, and increase concentration. Environmentally superior disposal techniques are demanding that such sludges have high mechanical strength properties. This results in a sludge with an increasing viscous character. At high concentration, the viscous forces – which are usually highly non-Newtonian and yield stress ...

Empirical orthogonal function (EOF) analysis has been widely used in meteorology and oceanography to extract dominant modes of behavior in scalar and vector datasets. For analysis of two-dimensional vector fields, such as surface winds or currents, use of the complex EOF method has become widespread. In the present paper, this method is compared with a real-vector EOF method that apparently has...

In a knowledge-intensive industry such as information technology, human resource management plays a central role in the success of software firms. This study takes a firm-level analysis and examines the effects of the human resource inflows and outflows on software firm performance. Moreover, we investigate how the specific human capital variables (e.g. education, experience) embedded in the hu...
