A kinetic Ising model description of Liesegang phenomena is studied using Monte Carlo simulations. The model takes into account thermal fluctuations, contains noise in the chemical reactions, and its control parameters are experimentally accessible. We find that noisy, irregular precipitation takes place in dimension d52 while, depending on the values of the control parameters, either irregular...

In this paper we deal with the utility maximization problem with a general utility function. We derive a new approach in which we reduce the utility maximization problem with general utility to the study of a fully-coupled Forward-Backward Stochastic Differential Equation (FBSDE).

In this paper, we provide an alternative definition of NTU convexity, strongly ordinal convexity. We show that if a game is strongly ordinal convex, then any marginal worth vector is in the core, and any marginal contribution is increasing. Some economic examples satisfy this convexity.

Nitrogen (N) is an essential major nutrient for food crops. Although ammonium (NH4+) the primary N source of rice (Oryza sativa), nitrate (NO3?) can also be absorbed and utilized. Rice responds to NO3? application by altering its root morphology, such as elongation. Strigolactones (SLs) are important modulators length. However, roles SLs their downstream genes in NO3?-induced elongation remain ...

Strigolactones (SLs) secreted from roots mediate symbiosis with arbuscular mycorrhizal fungi and can trigger germination of parasitic plants (reviewed in Al-Babili and Bouwmeester, 2015). SLs also influence shoot branching, root growth, and leaf shape (reviewed inWilliams and Yamaguchi, 2015). In SL signaling in rice (Oryza sativa), the DWARF3 F-box protein acts with the SL receptor DWARF14 as ...

We study the effect of frequent trading opportunities and categorization on pricing of a risky asset. Frequent opportunities to trade can lead to large distortions in prices if some agents forecast future prices using a simplified model of the world that fails to distinguish between some states. In the limit as the period length vanishes, these distortions take a particular form: the price must...

We analyze the impact of news (information shocks) in economies where liquidity plays a role. While we also consider news about real factors, like productivity, one motivation is that central bank announcements evidently affect markets, as taken for granted by advocates of forward guidance policy. The dynamic effects can be complicated, with information about monetary policy or real factors aff...
