American coot collective on-water dynamics.
American coot (Fulica americana) flocks exhibit water surface (two-dimensional) collective dynamics that oscillate between two primary phases: a disordered phase of low density and non-uniform coot body orientations; a synchronized phase characterized by high density, uniform body orientations and speed. For this small-scale study, data was obtained for flocks of 10 to ~250 members for these ph...
متن کاملHandling ligands with Coot
Coot is a molecular-graphics application primarily aimed to assist in model building and validation of biological macromolecules. Recently, tools have been added to work with small molecules. The newly incorporated tools for the manipulation and validation of ligands include interaction with PRODRG, subgraph isomorphism-based tools, representation of ligand chemistry, ligand fitting and analysi...
متن کاملPricing American Options on Bonds using Least Squares Simulation∗
In this project we discuss Least Square MonteCarlo methods for valuing American options on bonds. We investigate when we use different base functions, vary the number of base functions and sample paths, how the option price vary. From experiments, we know that we have better choose simple base functions, like Shifted Legendre polynomial; for the balance between time and accuracy issue, we sugge...
متن کاملDifferences in natural infections of two mortality-related trematodes in lesser scaup and American coot.
Populations of North American waterbirds, particularly lesser scaup, have been declining due to habitat disturbance, changing food resources, contaminants, bad water quality, and competition. However, epizootic diseases, including parasitism, may also play an important role in further decline. Trematode-associated mortality of migrating waterbirds, mainly American coot and lesser scaup, has bee...
متن کاملFeatures and development of Coot
Coot is a molecular-graphics application for model building and validation of biological macromolecules. The program displays electron-density maps and atomic models and allows model manipulations such as idealization, real-space refinement, manual rotation/translation, rigid-body fitting, ligand search, solvation, mutations, rotamers and Ramachandran idealization. Furthermore, tools are provid...
