the dedicated satellite mission goce will sense various small mass variations along its path around the earth. here we study the effect of the earth’s topography and atmosphere on goce data. the effects depend on the magnitude of topographic height, and they will therefore vary by region. as the effect of the atmosphere and topography must be removed from the total gravity anomaly prior to geoi...

ships’ magnetic anomalies are one of their main problems encountering sea mines and for the cases of submarines are one of the prominent factors, which causes their fast detection. the main aim of this paper is to design a degaussing system in order to minimize magnetic anomalies of ships. to achieve this goal, first, magnetic signature of a simple ship is simulated. then by utilizing three gro...

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

Our model shows that the discovery of an anomaly reduces its magnitude, regardless of whether the anomaly is due to risk or mispricing. After the discovery, the return from the anomaly becomes more correlated with the returns from other existing anomalies. While riskand mispricing-based anomalies have similar implications for asset prices, they have sharply different implications on investors’ ...

We consider a pseudoscalar axion-like field coupled to Chern-Simons gravitational anomaly term. The axion backreacts on rotating Kerr black hole background, resulting in modifications the spacetime. In an attempt determine potentially observable signatures, we study angular momentum of system modified Kerr-like and axionic matter outside horizon hole. As strength coupling term is increasing, re...

Binary F stars exhibit large brightness anomaly, which is defined here as the difference between the absolute magnitude from the uvby photometry and the actual absolute magnitude of the star. We have found that the anomaly inversely correlates with the binary components separation. There is evidence that the correlation reflects actual population differences between close and wide binary pairs,...

The accruals anomaly—the negative relationship between accounting accruals and subsequent stock returns—has been well documented in the academic and practitioner literatures for almost a decade. To the extent that this anomaly represents market inefficiency, one would expect sophisticated investors to learn about it and arbitrage the anomaly away. Yet, we show that the accruals anomaly still pe...

Seismic tomography revealed a low seismic velocity (-5%) and high Poisson's ratio (+6%) anomaly covering about 300 square kilometers at the hypocenter of the 17 January 1995, magnitude 7.2, Kobe earthquake in Japan. This anomaly may be due to an overpressurized, fluid-filled, fractured rock matrix that contributed to the initiation of the Kobe earthquake.
