The energy condition inequalities for the matter stress energy comprised out of the dilaton and Maxwell fields in the dilaton–Maxwell gravity theories emerging out of string theory are examined in detail. In the simplistic 1 + 1 dimensional models, R ≤ 0 (where R is the Ricci scalar), turns out to be the requirement for ensuring focusing of timelike geodesics. In 3 + 1 dimensions, we outline th...

The issue for the validation of land surface remote sensing albedo products over rugged terrain is the scale effects between the reference albedo measurements and coarse scale albedo products, which is caused by the complex topography. This paper illustrates a multi-scale validation strategy specified for coarse scale albedo validation over rugged terrain. A Mountain-Radiation-Transfer-based (M...

BACKGROUND AND METHODS Although Caribbean people have been a lesser-studied ethnic group than other populations, they have a high burden of hypertension and renal disease. Because Caribbean people have a greater muscle mass than Caucasians, this study examined the accuracy of creatinine-based estimates (creatinine clearance; C(cr) and Cockcroft-Gault formula; C-G Cl) of glomerular filtration ra...

Hepatic ethoxyresorufin-O-deethylase (EROD) activity was measured in black gobies (Gobius niger) collected from seven sampling sites along the Slovenian coast during spawning and non-spawning periods. Sediments from the same sites were tested for their toxicity and for total polycyclic aromatic hydrocarbon (PAH) content. EROD activity was significantly higher during the non-spawning period in w...

Recent theoretical work has solidified the viability of the collisional runaway scenario in young dense star clusters for the formation of very massive stars (VMSs), which may be precursors to intermediatemass black holes (IMBHs). We present first results from a numerical study of the collisional runaway process in dense star clusters containing primordial binaries. Stellar collisions during bi...

In our contribution, we model bank profitability via return-on-assets (ROA) and return-on-equity (ROE) in a stochastic setting. We recall that the ROA is an indication of the operational efficiency of the bank while the ROE is a measure of equity holder returns and the potential growth on their investment. As regards the ROE, banks hold capital in order to prevent bank failure and meet bank cap...

We study eccentric equatorial orbits of a test-body around a Kerr black hole under the influence of gravitational radiation reaction. We have adopted a well established two-step approach: assuming that the particle is moving along a geodesic ~justifiable as long as the orbital evolution is adiabatic! we calculate numerically the fluxes of energy and angular momentum radiated to infinity and to ...

Accurate modeling of the storage or sequestration of CO2 injected into subsurface formations requires an accurate fluid model. This can be achieved using compositional reservoir simulations. However, sophisticated equations of state (EOS) approaches used in current compositional simulators are computationally expensive. It is advantageous and possible to use a simple, but accurate fluid model f...

It has often been argued that there exists an underlying biological basis of utility functions. Taking this line of argument a step further in this paper, we have aimed to computationally demonstrate the biological basis of the Black-Scholes functional form as applied to classical option pricing and hedging theory. The evolutionary optimality of the classical Black-Scholes function has been com...

An increase in ambient carbonaceous particle (CNP) levels has been found, potentially leading to significant environmental/health hazards. These particles will ultimately enter the oceanic environment and interact with dissolved organic carbon. However, a detailed mechanistic understanding of their behavior, transport, and fate in marine systems is still much needed. This study, using carbon bl...
