The new experimental data concerning the effect of magnetic field on electric properties of silicon diodes with high doping levels both in the emitter and base (conduction of which at low temperatures is determined by the excess tunnel current) has been ...

Jet Collimation by Small-Scale Magnetic Fields [PDF]
A popular model for jet collimation is associated with the presence of a large-scale and predominantly toroidal magnetic field originating from the central engine (a star, a black hole, or an accretion disk). Besides the problem of how such a large-scale

Zero Magnetic Field Type Magnetic Field Sensor
AbstractThis paper presents a new magnetic field sensor named the zero magnetic field type, on the basis of its principle of operation, which is as follows: when the magnetic field level in the core used as a sensor is shifted by an unknown field to be detected, a controlled field is so superimposed in the opposite direction to the unknown field that ...

Magnetic Field Transfer From A Hidden Sector [PDF]
Primordial magnetic fields in the dark sector can be transferred to magnetic fields in the visible sector due to a gauge kinetic mixing term. We show that the transfer occurs when the evolution of magnetic fields is dominated by dissipation due to finite

External Field-Controlled Ablation: Magnetic Fields [PDF]
Laser ablation of silicon under an external applied magnetic field with different orientations was investigated in respect to the scanning direction and polarisation of the laser beam, by observation of the ablation patterns and debris deposition. Ultra-short ∼230 fs laser pulses of 1030 nm wavelengths were used in the single and multi-pulse ...

Computer Adaptive Testing Using Upper-Confidence Bound Algorithm for Formative Assessment
There is strong support for formative assessment inclusion in learning processes, with the main emphasis on corrective feedback for students. However, traditional testing and Computer Adaptive Testing can be problematic to implement in the classroom ...
