The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns

open access: yesAnnalen der Physik, EarlyView.
We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

On the Gauss map of quadric surfaces

open access: yes, 2019
In this paper, we study quadric surfaces in the 3-dimensional Euclidean space whose Gauss map n is of coordinate finite I-type, i.e., the position vector n satisfies the relation {\Delta}In = {\Lambda}n, where {\Delta}I is the Laplace operator with ...

Family of right conoid hypersurfaces with light-like axis in Minkowski four-space

open access: yesAIMS Mathematics
In the realm of the four-dimensional Minkowski space $ \mathbb{L}^{4} $, the focus is on hypersurfaces classified as right conoids and defined by light-like axes.

Harmonic Maps Surfaces and Relativistic Strings

open access: yesAIMS Mathematics, 2016
The harmonic map is introduced and several physical applications are presented. The classical nonlinear σ model can be looked at as the embedding of a two-dimensional surface in a threedimensional sphere, which is itself embedded in a four-dimensional ...

Hollow Polymer Droplets and Capsules Formed by Nonsolvent‐Induced Phase Separation

open access: yesAdvanced Physics Research, EarlyView.
Simulation snapshots illustrate the evolution of a polymer‐solvent droplet in a nonsolvent bath: 1) initial homogeneous droplet state, 2) intermediate stage with droplet shrinkage, skin formation, and macrophase‐separation onset, and 3) late stage with coarsened nonsolvent‐rich domains forming a hollow microparticle. Abstract Using large‐scale particle‐

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...
