Pull-apart basins are faulting and folding zones with high intensity of fractures that strongly affect the production in unconventional shale gas. While most observations pull-apart were from surface mapping or laboratory experiments, we investigated a nascent basin subsurface. We characterized along strike-slip fault within Woodford Shale by using seismic attributes analyses, including coheren...

The understanding of the interactions between subduction-induced mantle flow and background (being global or regional) remains incomplete despite its potential impact on subduction dynamics associated deformation. Here we present results three-dimensional laboratory models zones at scale upper in which systematically vary plate's width trench perpendicular flow. In particular, test different ma...

let (m,g ) be a compact immersed hypersurface of (rn+1,) , λ1 the first nonzeroeigenvalue, α the mean curvature, ρ the support function, a the shape operator, vol (m ) the volume of m,and s the scalar curvature of m. in this paper, we established some eigenvalue inequalities and proved theabove.1) 1 2 2 2 2m ma dv dvn∫ ρ ≥ ∫ α ρ ,2)( )2 2 1 2m 1 mdv s dvn nα ρ ≥ ρ∫ − ∫ ,3) if the scalar curvatu...

Recently, we have used the symmetric bracket of vector fields, and developed the notion of the symmetric derivation. Using this machinery, we have defined the concept of symmetric curvature. This concept is natural and is related to the notions divergence and Laplacian of vector fields. This concept is also related to the derivations on the algebra of symmetric forms which has been discu...

Recent reports have shown that saccades can deviate either toward or away from distractors. However, the specific conditions responsible for the change in initial saccade direction are not known. One possibility, examined here, is that the direction of curvature (toward or away from distractors) reflects preparatory tuning of the oculomotor system when the location of the target and distractor ...

We investigated in normal human subjects the effect of changing the initial direction on the kinematic properties of ®gure `8' movement performed as fast as possible by the right arm extended in free space. To this end, the motion of the index ®nger was monitored by the ELITE system. The ®gure `8' movement was characterized by a complex tangential velocity pro®le (Vt) presenting 5 bell-shaped c...

in this paper a new isolating system is introduced for short to mid-rise buildings. in comparison to conventional systems such as lrb and hrb, the proposed system has the advantage of no need to cutting edge technology and has low manufacturing cost. this system is made up of two orthogonal pairs of pillow-shaped rollers that are located between flat bed and plates. by using this system in two ...

In the second part of his prize-winning essay 1729, Bouguer (1698–1758) considers a light ray in spherically symmetric medium and introduces invariant named after him. He deduces an expression refraction integral, leading to table which is computed for particular atmospheric model. then studies influence ray’s curvature on horizon dip predicts hillingar effect. As complement, we recall that Bra...
