Eddington-inspired Born-Infeld gravity is an important modification of Einstein's general relativity, which can give rise to non-singular cosmologies at the classical level, and avoid end-stage singularity in a gravitational collapse process. In Newtonian limit, this theory gives modified Poisson's equation, as consequence stellar observables acquire model dependent corrections, compared ones c...

S U M M A R Y Fundamental to complex analysis is the Cauchy integral theorem, and the derivation of Cauchytype integrals. For over 40 yr, Cauchy-type integrals have been used to describe analytical continuation, establish the location of singular points, and study non-single-valued solutions of inverse problems in 2-D potential field theory. In this paper, we revive this interesting and fundame...

The present article summarizes the work of the papers [1] dealing with the quantization of pure gravity and gravity coupled to a Maxwell field and a cosmological constant in presence of spherical symmetry. Let us stress the following : the motivation for this project was not to quantize a black hole. Rather, we regard the present model as an interesting testing ground for the quantization of fu...

Predicting the volume and biomass of multi-stem maple trees (Acer monspessulanum Subsp. cinerascens Boiss.) based on standing traits is necessary in forestry. In this research twenty sample trees were selected in four transects randomly in Bagh-Shadi Forest of Yazd province. After measuring the diameter at root collar (DRC), tree height, stems numbers and crown diameter and area all trees were ...

a r t i c l e i n f o a b s t r a c t Keywords: climate Antarctica satellite measurements time-variable gravity While multiple data sources have confirmed that Antarctica is losing ice at an accelerating rate, different measurement techniques estimate the details of its geographically highly variable mass balance with different levels of accuracy, spatio-temporal resolution, and coverage. Some ...
