We estimate that from 500 million to possibly over 1 billion birds are killed annually in the United States due to anthropogenic sources including collisions with human-made structures such as vehicles, buildings and windows, power lines, communication towers, and wind turbines; electrocutions; oil spills and other contaminants; pesticides; cat predation; and commercial fishing by-catch. Many o...

Coronal jets are eruptions identified by a collimated, sometimes twisted spire. They small-scale energetic events compared with flares. Using multi-wavelength observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) and magnetogram Hinode/Spectro-Polarimeter (Hinode/SP), we study formation evolution of jet occurring on 2019 March 22 in active region NOAA 12736. A ...

A bstract We study dynamic processes through which the scalar hair of black holes is generated or detached in a theory with field non-minimally coupled to Gauss-Bonnet and Ricci invariants. concentrate on nonlinear temporal evolution far-from-equilibrium gravitational system. In our simulations, we choose initial spacetime be either bald Schwarzschild scalarized spherically symmetric hole. Succ...

Genetic algorithms abstract the fundamental processes of Darwinian evolution: natural selection and genetic variation through recombination and mutation. GAs can also implement non-Darwinian mechanisms such as Lamarckian search, in which local search is used to improve chromosomes, and Bald-winian search, in which local search improves chromosomes' tnesses but the chromosomes themselves are not...

Examination of bald eagles (Haliaeetus leucocephalus) collected from several locations in North America contributed new information concerning the acanthocephalan fauna of this host. Representatives of Arythmorhynchus brevis, representing a new host record, were collected from eagles in Florida, New Hampshire, and Wisconsin. Plagiorhynchus sp. was collected from an eagle in Florida. Corynosoma ...
