Abstract. Bed-material sediment particle size data, particularly the median (D50), are critical for understanding and modeling riverine transport. However, observations primarily available at individual sites. Large-scale assessment of transport limited by lack continuous regional maps bed-material size. We hence present a map D50 over contiguous US in vector format that corresponds to approxim...

Introduction Placement of a perirectal hydrogel spacer has been demonstrated to reduce the risk rectal toxicity from prostate radiation. Practices vary regarding timing CT simulation after placement, and ideal schedule remains unknown. Methods Thirty patients with localized adenocarcinoma underwent transrectal ultrasound-guided placement an iodinated SpaceOAR™ prior radiotherapy. Per evolving p...

The experiments of the effect particle size on flameless combustion characteristics and NOx emissions Shenmu semi-coke were launched a bench-scale coal preheating test rig. results revealed that difference fuel greatly influenced yield each component in high-temperature gas reactive activity char, thus subsequently affecting final process emissions. specific surface area pore volume both signif...

This paper studies competitive equilibria of a production economy with aggregate productivity shocks. There is a continuum of consumers who face borrowing constraints and individual labor endowment shocks. The dynamic economy is described in terms of sequences of aggregate distributions. The existence of competitive equilibrium is proven and a recursive characterization is established. In parti...

We propose a new solution concept to address the problem of sharing a surplus among the agents generating it. The problem is formulated in the preferences-endowments space. The solution is defined recursively, incorporating notions of consistency and fairness and relying on properties satisfied by the Shapley value for Transferable Utility (TU) games. We show a solution exists, and call it an O...

We study the evolution of comparative advantage in a model with two countries and`≥ 2 goods. We show that the stochastically stable set consists of the pattern of production that follows the chain of comparative advantage in a sufficiently large world economy. Also, the chain of comparative advantage has an elegant structure that allows for step-by-step evolution. So convergence towards the equ...

The paper studies insurance with moral hazard in a system of contingent-claims markets. Insurance buyers are modelled as Cournot monopolists or oligopolists. The other agents condition their expectations on market prices, as in models of rational-expectations equilibrium with asymmetric information. Thereby they correctly anticipate accident probabilities corresponding to effort incentives indu...

Beware of Workaholics: Household Preferences and Individual Equilibrium Utility This paper analyzes the effects of sociological changes in the form of a shift of influence within two-member households participating in labor and product markets. The most striking effects occur when household members differ in individual preferences and enjoy positive leisure-dependent externalities. For instance...

We consider a variant of the standard Arrow{Debreu model which contains a number of indivisible goods and one perfectly divisible good (numeraire or money). The objective of this paper is to clarify a general mathematical mechanism which guarantees the existence of an equilibrium in such a model. It is shown that the crucial condition for the existence of an equilibrium is that the sets of supp...
