The critical thickness for ferroelectricity and magnetoelectric effects have been investigated for the multiferroic tunnel junction with symmetric and asymmetric metallic electrodes based on density functional theory. The ferroelectric polarization of a barrier is still retained down to 2 unit...

"This Research Handbook provides a cutting-edge review of complex project organizing (CPO), and suggests fruitful avenues for future research with a focus on grand challenges and a sustainable future. Split into four sections, this Research Handbook addresses transitions within the field of CPO...

Primary healthcare institutions (PHIs) in China have experienced a sizable decline in medical services in recent years. Despite the large regional disparities in China, there is a lack of evidence on the differential patterns of medical services offered by PHIs, especially from a spatial...
