A Hybrid RF Coil for Whole‐Brain Imaging in Non‐Human Primates at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field MRI (≥ 7 T) offers unprecedented potential for mapping non‐human primate (NHP) brain function. However, complex electromagnetic systems are required to meet the challenges of UHF imaging and the mechanical demands of awake NHP studies.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Estimation of dielectric constant for various standard materials using microstrip ring resonator [PDF]

, 2017
Microstrip ring resonator (MRR) is known for dielectric constant determination and many studies used Teflon as a standard sample. However, there are many other materials available which able to perform better or equivalence as the Teflon in calibrating ...

Enabling rural broadband via TV "white space" [PDF]

, 2012
The use of multiple frequency bands within a wireless network allows the advantages of each band to be exploited. In this paper we discuss how HopScotch, a rural wireless broadband access test bed running in the Scottish Highlands and Islands, uses both ...

Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

High Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, EarlyView.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.
