While boride clusters of alkali and transition metals have been observed and extensively characterized, so far little is known about lanthanide−boron clusters. Lanthanide−boride solids are intriguing, however, and therefore it is of interest to understand the fundamental electronic properties of such systems, also on the subnano scale. We report a joint experimental photoelectron spectroscopic ...

[1] We analyze the temperature anomaly of the Pinatubo eruption using an exact mathematical solution of a standard energy balance model that includes coupling between the mixed layer and the thermocline. Our solution yields a short response time t = 4.4 months and a small climate sensitivity l = 0.22 C/(W/m), implying short-term negative feedback. Also, our analysis determines a value of the ef...

We study a growth model for a single resource-based economy, as an infinite-horizon optimal control problem. The resource is assumed to be governed by the standard model of logistic growth, and is related to the output of the economy through a Cobb-Douglass type production function with an exogenously driven knowledge stock. The problem involves unbounded controls and the non-concave Hamiltonia...
