Eos, Transactions American Geophysical Union, 1989 At the recently concluded International Association of Geomagnetism and Aeronomy Assembly in Exeter, U.K., magnetic domain observations on magnetite imaged for the first time by the magneto‐optic Kerr effect were reported. The picture (Figure 1) shows domains on a synthetic magnetite grain where magnetic contrast is achieved by the longitudinal Kerr ...

Weak Magnetic Anomaly Signal Extraction Method Based on EEMD and DWT
水下无人系统学报, 2023 Magnetic anomaly signal contains rich feature information of targets, which is the basis for target localization and identification. However, the magnetic anomaly generated by the target rapidly attenuates with detection distance, making the weak ...

Configurational anisotropy in single-domain and pseudosingle-domain grains of magnetite [PDF]
, 2006 In classical domain theory, single-domain (SD) grains change their magnetization by coherent rotation, where the energy barrier to domain reversal is provided by the magnetocrystalline anisotropy or by shape anisotropy for elongated grains.

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...
