We study an inhomogeneous sandpile model in which two different toppling rules are defined. For any site only one rule is applied corresponding to either the Bak, Tang, and Wiesenfeld model [P. Bak, C. Tang, and K. Wiesenfeld, Phys. Rev. Lett. 59, 381 (1987)] or the Manna two-state sandpile model [S. S. Manna, J. Phys. A 24, L363 (1991)]. A parameter c is introduced which describes a density of...

Understanding the ability of koalas to respond to changes in their environment is critical for conservation of the species and their habitat. We monitored the behavioural response of koalas to declining food resources in manna gum (Eucalyptus viminalis) woodland at Cape Otway, Victoria, Australia, from September 2011 to November 2013. Over this period, koala population density increased from 10...

        Infant jaundice is observed during the first week of life in approximately 60% of term and 80% of preterm infants. Hyperbilirubinemia may lead to the development of kernicterus, hearing loss, and convulsion. The goal of therapy in hyperbilirubinemia is lowering blood bilirubin levels or at least preventing its increase. It is recommended that phototherapy and if unsuccessful, blood exch...

We apply the Painlevé test for integrability to the new discrete nonlinear Schrödinger equation introduced by Leon and Manna. Since the singular expansions of solutions of this equation turn out to contain non-dominant logarithmic terms, we conclude that the studied equation is nonintegrable. This result supports the recent observation of Levi and Yamilov that the Leon–Manna equation does not a...
