Effect of extinction on the high-energy optical response of photonic crystals [PDF]
, 2007 An analysis of the optical response of photonic crystals in the high-order band energy range is herein presented. High and abruptly fluctuating specular reflectance is predicted for perfect lattices at those energies even in the absence of any photonic ...

Micromollusk families in 2 contrasting seasons in Bahia de los Angeles, Gulf of California, Mexico
Ciencias Marinas, 2023 Marine mollusks provide important ecosystem services. They create habitats for benthic organisms, filter water, biodeposit organic carbon in the seafloor, and serve as food sources for other organisms. Studies of mollusk diversity require time-consuming

The Gulf of California is a source of carbon dioxide to the atmosphere
Ciencias Marinas, 2013 Water exchange between the Gulf of California and the Pacific Ocean has a significant vertical component (VCWE). Surface (0–200 m) gulf water flows out into the Pacific Ocean and deep (200–600 m) water flows into the gulf.
