A 28-GHz Cascode Inverse Class-D Power Amplifier Utilizing Pulse Injection in 22-nm FDSOI
IEEE Access, 2020 Current Mode Class-D (CMCD) Power Amplifiers are of particular interest in outphasing transmitters or Doherty configuration. This is because the output capacitance can be absorbed in the RLC output matching network and 100% theoretical efficiency.

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife
Wildlife Biology, EarlyView.As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Demographic buffering in natural populations: A multi‐level perspective
Journal of Animal Ecology, EarlyView.We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.
