Potentially zoonotic Mycobacterium spp. are impacting freshwater ornamental fish in Trinidad and Tobago. Clinical cases presented at the Aquatic Animal Health Unit of The University of the West Indies, School of Veterinary Medicine, from September 2011 to September 2018 indicated the presence of piscine mycobacteriosis in freshwater ornamental fish from locations throughout Trinidad and Tobago.

In the presence of global conservation laws holding on the joint meter-target system, the Wigner-Araki-Yanase theorem and its generalizations predict a lower bound on the measurement's error (Ozawa's bound). While practically negligible for macroscopic meters, it becomes relevant for microscopic ones.

Despite a large body of literature on this phenomenon, concerns persist regarding previous developmental research populations that are small and lack racial/ethnic diversity. In addition, it remains unclear what role holding membership within and interacting with specific racial/ethnic groups plays in the development of children's group attitudes.

While generating supergrowth on demand requires precise source modulation, we demonstrate that supergrowth occurs naturally in a sum of random plane waves. We measure the supergrowing fractional area of transverse, monochromatic, fully developed speckle patterns.
