Magnetic Control of Recombination Fluorescence and Tunability by Modulation of Radical Pair Energies in Rigid Donor-Bridge-Acceptor Systems.

Journal of the American Chemical Society, 2020
Magnetic control of molecular emission holds the promise of developing new magneto-optical technologies. Spin dynamics of radical pairs can serve as a basis of control of chemical reactions by weak magnetic fields (

Magnetic Control of a Flexible Needle in Neurosurgery

IEEE Transactions on Biomedical Engineering, 2020
Minimally invasive neurosurgery does not require large incisions and openings in the skull to access the desired brain region, which often results in a faster recovery with fewer complications than traditional open neurosurgery.

Magnetically Controlled Variable Logic

IBM Journal of Research and Development, 1964
Magnetically controlled multipurpose logic provides a great flexibility and compactness. A matrix consisting of 2n saturable magnetic elements for n variable inputs is controlled by an adjacent magnetic pattern recorded on a magnetic medium, which determines the logical function to be performed.

A Controlled Magnetic Clamp

Instruments and Experimental Techniques, 2012
A clamp for creating the thermal contact in vacuum between components of the cryostat on its preliminary cooling is described. The contact is established when heating conduits are pressed towards one another by a permanent magnet and is broken (established) when current pulses of appropriate polarity are applied to the winding around the iron magnetic ...

Robust stabilization of spacecraft attitude motion under magnetic control through time‐varying integral sliding mode

International Journal of Robust and Nonlinear Control, 2019
Magnetic spacecraft attitude control is suitable for missions with moderate pointing and stabilization requirements. It would be especially preferable if an implemented three‐axis magnetic control law guarantees global and moreover robust stabilization ...

Directed Self-Assembly of Templatable Block Copolymers by Easily Accessible Magnetic Control.

Small, 2019
Magnetic control has been a prosperous and powerful contactless approach in arraying materials into high-order nanostructures. However, it is tremendously difficult to control organic polymers in this way on account of the weak magnetic response.

Design of LLC Resonant Converter with Magnetic Control for LEV Application

International Symposium on Power Electronics for Distributed Generation Systems, 2019
In this paper, analysis and design of the LLC resonant converter with magnetic control for light electric vehicles (LEVs) application are presented. The magnetic control instead of the widely used frequency control or phase shift control is adopted for ...

Derivative controlled magnetic amplifiers

Electrical Engineering, 1954
THE CIRCUIT shown in Fig. 1 is of a low-level fast-response magnetic amplifier, as developed for such low-level signals as are provided by thermocouples, strain gauges, etc. Rectifiers are not included in the input circuit, thus eliminating the restriction which they impose on the minimum signal voltage.

Magnetic Control of Axon Navigation in Reprogrammed Neurons.

Nano letters (Print), 2019
While neural cell transplantation represents a promising therapy for neurodegenerative diseases, the formation of functional networks of transplanted cells with host neurons constitutes one of the challenging steps. Here, we introduce a magnetic guidance
