An on-body antenna, comprised of two closely-spaced antiphase patch elements, for microwave imaging may provide enhanced signal penetration into the tissue. By further integrating a 180-degree on-chip power combiner with dual antenna element, low-profile miniaturized integrated single 18.5 mm x 10 1.6 circuit board assembly, is designed and evaluated both numerically experimentally. This smallest known to authors given frequency band. linearly polarized potentially serve as building block...
The N-terminally truncated pyroglutamate Aβ3-42 (AβpE3-42) and Aβ4-42 peptides are known to be highly abundant in the brain of Alzheimer's disease (AD) patients. Both show enhanced aggregation neurotoxicity comparison full-length Aβ, suggesting that these amyloid may play an important role pathogenesis AD. aim present work was study direct effect combination AβpE3-42 on ongoing AD-related neuron loss, pathology, neurological deficits transgenic mice. Bigenic mice were generated by crossing...
Objective: There is an unmet need for quick, physically small, and cost-effective office-based techniques that can measure bone properties without the use of ionizing radiation. Methods: The present study reports application a neural network classifier to processing previously collected data on very low power radiofrequency propagation through wrist detect osteoporotic/osteopenic conditions. Our approach categorizes obtained two dichotomic groups. Group 1 included 27 subjects with Bone...
On-body antennas for use in microwave imaging (MI) systems can direct energy around the body instead of through body, thus degrading overall signal-to-noise ratio (SNR) system. This work introduces and quantifies usage modern metal-backed RF absorbing foam conjunction with on-body to dampen flowing using both simulations experiments. A head system is demonstrated herein but principle be applied any part including torso or extremities. computational model was simulated numerically Ansys HFSS....
Societies tend to partition into factions based on shared beliefs, leading sectarian conflict in society.This paper investigates mistrust as a cause for this partitioning by extending an established opinion dynamics model with Bayesian updating that specifies the underlying mechanism disagreement and, ultimately, polarisation.We demonstrate is at foundation of polarisation.Detailed analysis and results rigorous simulation studies provide new insight potential role show consensus when levels...
This preliminary study reports application of a neural network classifier to the processing previously collected data on low power radiofrequency propagation through wrist with goal detect osteoporotic/osteopenic conditions. The set used includes 67 subjects (23-94 years old, 50 females, 17 males, 27 osteoporotic/osteopenic, 40 healthy). We process entire spectrum coefficient from 30 kHz 2 GHz, 201 sampling points in total. found that dichotomic diagnostic test raw non-normalized performed...
