Inversion of Gamow’s formula and inverse scattering

open access: yesAmerican Journal of Physics, 2006
Gamow’s tunneling formula is inverted and the issue of the uniqueness of the solution is compared with the solution obtained by the method of Gel’fand and Levitan. Some insight is gained into the key differences between classical and quantum inverse scattering, which account for the fact that a potential can be uniquely determined in the latter but ...

Inversion of thermal properties of lunar soil from penetration heat of projectile using a 2D axisymmetric model and optimized PSO algorithm

open access: yesFrontiers in Materials, 2022
The thermophysical parameters of lunar soil can be inferred from the temperature field during the invasion process of reconnaissance projectile. This paper adopts a two-dimensional axisymmetric model to reconstruct the projectile invasion process.

Inverse-Cycles in Weak-Inverse Loops [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
In a loop let J be the map taking every element into its right inverse. If the order of J is n, then { x , x J , … , x J n − 1 } \{ x,xJ, \ldots ,x{J^{n - 1}}\} is called

Inverse Problems Have Inverse Complexity [PDF]

open access: yes, 2008
In this paper we show that inverting problems of higher complexity is easier than inverting problems of lower complexity. While inverting Σp i3CNFSAT is known to be coNP-complete sideri for i=1 we prove that it remains coNP-complete for i=2 and is in P for all i⩾ 3. Relatedly, we show that inverting Σp i3DNFSAT is in P for all i⩾ 1.
