CPW-fed oscillating microstripantennas
Electronics Letters, 1996 Operating with a low-cost FET, oscillating CPW-fed microstrip antennas working at /spl sim/4 GHz have been presented. Because the design is based on slot or slot loop apertures, no via holes are required, These oscillating antennas are compact, easy to fabricate while providing uniform radiation patterns with cross-polarisation levels below -17 dB ...

Trends in thunderstorm days, lightning activity, squalls and the environmental factors in Hong Kong
Weather, EarlyView.This study analyses trends in Hong Kong's convective weather using long‐term observer‐based and shorter‐term instrument‐based data. Annual thunderstorm days increased significantly by 1.9 days decade−1 in 1947–2024, notably in June–September, consistent with increasingly favourable warm‐season environments for thunderstorms.

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Abundance, trends, and challenges facing mountain goats throughout their North American distribution
Wildlife Society Bulletin, EarlyView.Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...
