Analysis and Design of Cavity-Backed Probe-Fed Hybrid Microstrip Antennas on FR4 Substrate
International Journal of Antennas and Propagation, 2015 A novel cavity-backed probe-fed linearly polarized microstrip antenna based on the concept of hybrid radiators is proposed and implemented. The resulting flush-mounted antenna exhibits symmetrical bandwidth, low cross-polarization radiation in the H ...

Analytical Model for Predesigning Probe-Fed Hybrid Microstrip Antennas
International Journal of Antennas and Propagation, 2018 Based on the equivalent resonant cavity model, an effective analysis methodology of probe-fed hybrid microstrip antennas is carried out in this paper, resulting in a better understanding of the parameter interrelations affecting their behavior. With that,

Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]
Ecol EvolClimate change is projected to sharply reduce suitable habitats for eight endemic rupestrian plant species in Brazil's Iron Quadrangle. Ensemble niche models reveal species‐specific vulnerabilities and highlight climatic refugia and corridors that may support persistence.

Providing long‐term care: Options for a better workforce
International Social Security Review, Volume 75, Issue 3-4, Page 121-144, July-December 2022., 2022 Abstract Older people and their care workers have been disproportionately affected by the COVID‐19 pandemic. Many OECD Member countries have taken measures to contain the spread of the infection and improve the care workforce. Yet the health crisis is highlighting and exacerbating pre‐existing structural problems in the long‐term care (LTC) sector.

Methods in Ecology and Evolution, Volume 12, Issue 9, Page 1609-1619, September 2021., 2021 Abstract Georeferenced biological data of species distributions, abundances or traits are critical for ecological and evolutionary research. However, the accuracy (true vs. false records) and biogeographical status (native vs. alien) of individual georeferenced records are often unclear, which limits their use in species distribution modelling ...
