In this contribution, we are concerned with the detection and reened subvoxel localization of 3D point landmarks. We propose multi-step differential approaches which are generalizations of an existing two-step approach for subpixel localization of 2D point landmarks. This two-step approach combines landmark detection by applying a diierential operator with reened localization through a diierent...

We present a result of localization for a matrix-valued AndersonBernoulli operator, acting on L2(R) ⊗ R , for an arbitrary N ≥ 1, whose interaction potential is generic in the real symmetric matrices. For such a generic real symmetric matrix, we construct an explicit interval of energies on which we prove localization, in both spectral and dynamical senses, away from a finite set of critical en...

In this contribution, we are concerned with the detection and reened localization of 3D point landmarks. We propose multi-step diierential procedures which are generalizations of an existing two-step procedure for subpixel localization of 2D point landmarks. This two-step procedure combines landmark detection by applying a diierential operator with reened localization through a diierential edge...

We study the kicked rotator in the classically fully chaotic regime using Izrailev's N-dimensional model for various N≤4000, which in the limit N→∞ tends to the quantized kicked rotator. We do treat not only the case K=5, as studied previously, but also many different values of the classical kick parameter 5≤K≤35 and many different values of the quantum parameter kε[5,60]. We describe the featu...

We show that the BRST charge for the N=2 superstring system can be written as Q = e −R (dz 2πi bγ + γ −)e R , where b and γ ± are super-reparametrizations ghosts. This provides a trivial proof of the nilpotence of this operator.

We investigate the possibility of spin-preserving symmetries due to the interplay of Rashba and Dresselhaus spin-orbit coupling in n-doped zinc-blende semiconductor quantum wells of general crystal orientation. It is shown that a conserved spin operator can be realized if and only if at least two growth direction Miller indices agree in modulus. The according spin-orbit field has in general bot...
