There has clearly been significant volcanic activity on the surface of Venus in recent geological epochs and there is a great deal of indirect evidence that this may continue at the present time. However, the current level of activity is unknown and remains controversial, with estimates for the rate of emission of volcanic gases into the atmosphere ranging from essentially quiescent to very hig...

We demonstrate picosecond, high-contrast population flipping of two-level atoms interacting with femtojoule optical pulses in a 3D photonic band gap waveguide. This is the result of giant Mollow splitting caused by strong light localization and a remarkable field-dependent relaxation of the atomic Bloch vector as it evolves near an abrupt jump in the electromagnetic density of states. Unlike st...

A few months ago, my fiancé and I, after much consideration, decided to stop using condoms and rely only on the Pill as a contraceptive method. Since then, when he ejaculates inside my vagina, I frequently experience a strong burning sensation a few minutes afterward ? varying in both degree and length each time. Could I be allergic to his semen? The pain sometimes subsides if I hold a wet clot...

Economists have suggested that the quality of higher education is not independent of the sources of funds used to fund that education. This paper examines the relationship between student measures of teaching quality and institutional revenue sources. The results indicate that a greater reliance on private subsides is associated with higher measures of teacher quality. A greater reliance on pub...

We find that weekend, holiday and overnight trading breaks generate excessive perceived risk in the option markets, presumably due to asymmetric information, which, in turn, encourages uninformed option traders to postpone trading. This perceived risk subsides after two days accompanied by an increase in the option trading volume and the underlying index’s actual price volatility. These results...

Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...
