Abstract: A frequency-reconfigurable Fabry–Perot (F-P) antenna with low radar cross section (RCS) is proposed in this work. A multifunctional liquid metal high impedance surface (HIS) is employed on ...

Abstract: A broadband, low-insertion-loss frequency selective rasorber (FSR) for broadband antennas is proposed. Different from the traditional method of expanding transmission bandwidth by adding ...

The authors of a new study have reported that having higher levels of vitamin D was associated with lower levels of tau protein — a biomarker for Alzheimer’s disease — several years later. “These ...

Higher levels of vitamin D in early midlife were associated with significantly lower levels of tau deposition 16 years later in adults without dementia. Results of a prospective, community-based ...
