A major virtue of von Neumann-Morgenstern utilities, for example, in the theory of general financial equilibrium (GFE), is that they ensure intertemporal consistency: consumption-portfolio plans (for the future) are in fact executed (in the future) — assuming that there is perfect foresight...

In this paper we discuss interacting particles in an external magnetic field. By comparing the Schrödinger equation of three interacting particles with the associated Laguerre differential equation, we obtain the energy spectrum which corresponds to indices n<Subscript>i</Subscript> and m<Subscript>i</Subscript>. Finally by using the so...</subscript></subscript>

Many avian species initiate incubation before clutch completion, which causes eggs to hatch asynchronously. This influences brood competitive dynamics and often results in nestling mortality. The prevailing hypotheses contend that parents incubate early because asynchronous hatching provides...
