This article reviews the charge transport and photogeneration in bulk-heterojunction solar cells made from blend films of regioregular poly(3-hexylthiophene) (RR-P3HT) and methano-fullerene (PCBM). The charge transport, specifically the hole mobility in the RR-P3HT phase of the polymer:fullerene photovoltaic blend, is dramatically affected by thermal annealing. The hole mobility increases more ...

The present article considers the situation in which the buyer’s taste and budget are his private information. In this multi-dimensional setting, we study the optimal mechanism through a canonical mechanism in the traditional one-dimensional context: a function of one variable, the buyer’s taste. In our multi-dimensional context, however, this is an indirect mechanism. We investigate the effect...

Lupus-prone, anti-DNA, heavy (H) chain "knock-in" mice were obtained by backcrossing C57BL/6 mice, targeted with a rearranged H chain from a VH11(S107)-encoded anti-DNA hybridoma (D42), onto the autoimmune genetic background of New Zealand Black/New Zealand White (NZB/NZW) F1 mice. The targeted female mice developed typical lupus serologic manifestations, with the appearance of transgenic IgM a...

Kritikos and Bolle’s approach is still flawed, but a viable indenture game can still readily be structured within the context of iterated prisoner’s dilemma. © 2000 Published by Elsevier Science B.V. JEL classification: C70

To elucidate the function of keratins 8 and 18 (K8/18), major components of the intermediate filaments of simple epithelia, we searched for K8/18-binding proteins by screening a yeast two-hybrid library. We report here that human Mrj, a DnaJ/Hsp40 family protein, directly binds to K18. Among the interactions between DnaJ/Hsp40 family proteins and various intermediate filament proteins that we t...

Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Näıvety of both is related to the idea that higher prices exclude worse qualities. While competition of näıve buyers increases prices, competition of näıve sellers promotes efficiency enhancing trade. Our predictions are teste...

We extend Armstrong’s [1] result on exclusion in multi-dimensional screening models providing support for the view that the result holds true in a large class of models. We first relax some of the strong technical assumptions he imposed and provide alternative su cient conditions for exclusion not relying on any form of convexity. We then proceed to show that exclusion obtains generically. We i...

We give examples of strategic interaction which are beneficial for players who follow a "middle path" of balance between pure selfishness and pure altruism. JEL Classification: C70, C71, C72, C79.
