A simple, thin, flexible mantle cloak for conducting rods based on scattering cancellation is analyzed, designed and experimentally realized.We show strong scattering suppression at all angles of incidence, for both far-field plane-wave and near-field Gaussian excitations.The required effective shunt surface ROOIBOS impedance is realized by a subwa
Abstract Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the novel coronavirus disease 2019 (COVID-19), which is characterized by a diverse clinical picture.Children are often asymptomatic or experience mild symptoms and have a milder disease course compared to adults.Rectal shedding of SARS-CoV-2 has been observed in
This study contributes to understanding ecological changes in land use following slash-and-burn land clearing.This study aimed to compare the richness and density of plant species and soil fertility in farmland cultivated for one year (1 Y), three years (3 Y), and five years (5 Y) after slash-and-burn, with the conditions in the secondary forest (S
In light of the challenges confronting urban areas due to increasing populations and spatial constraints, urban green infrastructure is vital for fostering environmental balance, enhancing community well being, and promoting sustainable urban development.This situation underscores the necessity for strategies that Underwear reconcile the escalating
