尽管D—INSAR技术有定期常规精确监测滑坡的巨大潜力，但对于监测火山和地震断层的活动仍然面临着挑战。时间去相关和大气异质性构成了主要的限制。时间去相关使。INSAR测量在植被覆盖地区无法应用，通常这些地区的电磁剖面或每个分辨率单元内散射体的位置会随时间而变化。另一方面，在估算DEM和形变模式时，大气异质性引起的低波数变化也会受人为因素的影响。

Behavior is predicted to be a primary determinant of the success of the invasion process during the early phases of *** invaders with sympatric native species may provide a good approach to unravel behavioral traits involved in an invasion *** this study,we carried out an experimental simulation of the introduction and the acclimatization phase into a new environment and assessed the expression of activity,alertness,and habituation in an invasive Mediterranean population of the South African nudibranch Godiva quadricolor comparing its profles with those of the sympatric Mediterranean native nudibranchs Cratena peregrina and Caloria *** of these 3 species were subjected to 3 behavioral tests:spontaneous activity,carried out in the introduction phase(immediately after sampling)and after a week of acclimatization;alert test,in which a potential threat was simulated by means of a tactile stimulus,and habituation test,in which the same alert test stimulus was repeated 5 times at 30-min *** invasive *** showed higher levels of exploration activity,thigmotaxis,alertness,and sensitization than the native *** behavioral traits may represent pivotal drivers of the ongoing invasion process.

Journal of Computational Mathematics 2010年第4期28卷 461-473页

作者： Roberto ferretti Dipartimento di Matematica Università di Roma Tre

We compare in this paper two major implementations of large time-step schemes for advection equations, i.e., Semi-Lagrangian and Lagrange-Galerkin techniques. We show that SL schemes are equivalent to exact LG schemes via a suitable definition of the basis functions. In this paper, this equivalence will be proved assuming some simplifying hypoteses, mainly constant advection speed, uniform space grid, symmetry and translation invariance of the cardinal basis functions for interpolation. As a byproduct of this equivalence, we obtain a simpler proof of stability for SL schemes in the constant-coefficient case.

We consider in this paper a high-order,semi-Lagrangian technique to treat possibly degenerate advection-diffusion equations,which has been proposed in similar forms by various *** scheme is based on a stochastic representation formula for the solution,which allows to avoid the splitting between advective and diffusive part of the evolution operator.A general theoretical analysis is carried out in the paper,with a special emphasis on the possibility of using large Courant numbers,and numerical tests in one and two space dimensions are presented.
