Systematics in lensing reconstruction: Dark matter rings in the sky? [PDF]
, 2011 Non-parametric lensing methods are a useful way of reconstructing the lensing mass of a cluster without making assumptions about the way the mass is distributed in the cluster. These methods are particularly powerful in the case of galaxy clusters with a

Cryo-EM map interpretation and protein model-building using iterative map segmentation. [PDF]
, 2020 A procedure for building protein chains into maps produced by single-particle electron cryo-microscopy (cryo-EM) is described. The procedure is similar to the way an experienced structural biologist might analyze a map, focusing first on secondary ...

Metric Density and Quasimobius Mappings [PDF]
Siberian Mathematical Journal, 2002 Summary: We study the notion of \(\mu\)-density of metric spaces which was introduced by V.~V.~Aseev and D.~A.~Trotsenko. An interrelation between the \(\mu\)-density and homogeneous density is established. We also characterize \(\mu\)-dense spaces as ``arcwise'' connected metric spaces in which ``arcs'' are the quasimöbius images of the middle-third ...

Is the dynamics of open quantum systems always linear?
, 2003 We study the influence of the preparation of an open quantum system on its reduced time evolution. In contrast to the frequently considered case of an initial preparation where the total density matrix factorizes into a product of a system density matrix
