MRI-guided robotic arm drives optogenetic fMRI with concurrent Ca2+ recording
Nature Communications, 2019 Fiber optic implantation in deep areas of the rodent’s brain for MRI combined with optogenetics is challenging. Here the authors use an MRI-guided robotic arm as the navigation method for accurate fiber optic placement and precise microinjection during ...

Magnetically Controlled 3D Cartilage Regeneration
CARTILAGE, 2023 Objective The cartilage regeneration field has not yet overcome the issue of effective “shaping”: growing regenerated cartilage in the desired shape, and maintaining that shape, is problematic. This study reports on a new method of cartilage regeneration in which the cartilage is shaped in three dimensions. Since cartilage is composed only of cartilage

Control of stochasticity in magnetic field lines [PDF]
, 2005 We present a method of control which is able to create barriers to magnetic field line diffusion by a small modification of the magnetic perturbation. This method of control is based on a localized control of chaos in Hamiltonian systems.

Topological control of magnetic textures
Physical Review B, 2021 A micromagnetic study is carried out on the role of using topology to stabilize different magnetic textures, such as a vortex or an anti-vortex state, in a magnetic heterostructure consisting of a Permalloy disk coupled to a set of nanomagnetic bars. The topological boundary condition is set by the stray field contributions of the nanomagnet bars and ...

Robust active magnetic dearing control using stabilizing dynamical compensators [PDF]
, 1999 The robust control of active magnetic bearings, based on a linearised interval model, is considered. Through robust stability analysis, all the first-order robust stabilizing dynamical compensators for the interval system are obtained.

International Journal of Research -GRANTHAALAYAH, 2015 It is physically impossible for the miniscule gas, Carbon Dioxide with an Atomic Weight of 44, to influence the Earth’s orbital position in space. The knowledge of magnetism has always been a wonder of the ancient world ever since it was realized that a lodestone pointed in the same direction.
