DEVELOPMENT OF SUBSTRATE-INTEGRATED WAVEGUIDE FILTERS FOR LOW-COST HIGH-DENSITY RF AND MICROWAVE CIRCUIT INTEGRATION: DIRECT-COUPLED CAVITY BANDPASS FILTERS WITH CHEBYSHEV RESPONSE

Direct-coupled cavity bandpass filters with Chebyshev Storage Basket response are studied and realized, using the technique of planar substrate-integrated waveguide (SIW) for the purpose of high-density integration and cost reduction.Using a general mode-matching technique, the scattering matrix of waveguide bifurcation-type discontinuity and asymm

The loss of nutrients from fertilizers can impair surface and ground waters.Environmentally sensitive crop management requires applying only enough fertilizer to ensure economic crop yields.We found that Storage Basket sugarbeets grown in soils rich in organic matter in the Upper Klamath Basin Decorations can be fertilized at very low rates and use

Parent-offspring conflict theory predicts the emergence of weaning conflict between a mother and her offspring arising from skewed relatedness benefits.Empirical observations of weaning conflict have not been carried out in canids.In a field-based study on free-ranging dogs we observed that nursing/suckling bout durations decrease, proportion of mo

Zoonotic simian foamy viruses (SFV) establish lifelong infection in their human hosts.Despite repeated transmission of SFV from nonhuman primates to humans, neither transmission between human hosts nor severe clinical manifestations have been reported.We aim to study the immune responses elicited by chronic infection with this retrovirus and previo

The agri-food sector is undergoing a comprehensive transformation as it Tulip Knob transitions towards net zero.To achieve this, fundamental changes and innovations are required, including changes in how food is produced and delivered to customers, new technologies, data and physical infrastructures, and algorithmic advancements.In this paper, we e
