Abstract The recent results of the BICEP and Keck collaborations have put stringent bounds on many inflationary models, including some well-motivated ones. This is certainly case when gravity remains described by Einstein's theory up to scale, but can be avoided introducing quadratic-in-curvature terms that are effective at scale. Recently it has also been shown these UV complete respecting sta...

The aim of ESA's satellite mission GOCE is to determine the Earth's gravity field with high accuracy and resolution. To achieve this aim, GOCE carries a gravitational gradiometer that needs calibration. Existing global gravity fieldmodels in combinationwith GOCE star sensor data may be used to synthesize reference differential accelerations with which the common and differential accelerations, ...

Using a gravity model of trade and the U.S. and Chinese panel data, I present evidence that supports the views that linguistic links have become more important in foreign trade than geographical proximity and that linguistic influence on trade is more significant in China than in the U.S. The estimated result based on a broad panel of economies shows little overall relation between religious si...

The four-dimensional metric f(R) theories of gravity are cast into connection-dynamical formalism with real su(2) connections as configuration variables. Through this formalism, the classical metric f(R) theories are quantized by extending the loop quantization scheme of general relativity. Our results imply that the nonperturbative quantization procedure of loop quantum gravity is valid not on...

While the gravity model has been one of the most successful applications in empirical trade, various attempts are still made to improve its regression results. One of the recent developments in the econometric technique is to extend the gravity model to a panel data framework and take into consideration the existence of dynamic effects. In this paper, we apply these new techniques to examine th...

[1] In 2005 an extensive new seismic refraction data set was acquired over the central part of the Chicxulub impact crater, allowing us to image its structure with much better resolution than before. However, models derived from traveltime data are limited by the available ray coverage and the nonuniqueness that is inherent to all geophysical methods. Therefore, many different models can fit th...

We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...

due to increasing number of international tourists and the enhancing role of tourism in economies of countries and competing environment, recognizing determinants in attracting international tourists seems very essential than ever before. public and private sectors need to examine determinants and forecast tourism demand. the primary aim of this study is using econometric techniques to analyzin...
