One of the main predictions of principal-agent theory, the “informativeness principle”, is often violated in practice. We propose an explanation that emphasizes the role played by the change in the form of the optimal contract that follows an improvement in informativeness. We show that the overall gains from a less noisy performance measure emanate from two sources: the direct effect of a chan...

The Nanoimprint lithography (NIL) is a novel method of fabricating micro/nanometer scale patterns with low cost, high throughput and high resolution (Chou et al., 1996). Unlike traditionally optical lithographic approaches, which create pattern through the use of photons or electrons to modify the chemical and physical properties of the resist, NIL relies on direct mechanical deformation of the...

the counters of e to become nil: message tokense] is decremented by 1, but nil tokense] is incremented by 1. 2 Proof of Lemma 2: Let t be the time just before the token is sent from u, and t 0 the time just before it is received at v. Because the sum of message tokens and nil tokens can increment only when tokens arrive on the link, and because the links are FIFO, we have: message tokense] t 0 ...

up By the induction hypothesis P fulfil the requirements. Let be a node in P’s frontier that such that P( ) = ht;Ri is non-trivial, and let P( ) = ht 0;R 0i be a non-trivial ancestor such that t 0 t. Let t 0 u t = (s; fx1:=s1; : : : ; xn :=sng; ). Since t 0 6$ t, s is not a variable. Also, since t 0 6 lt, then sfx1:= s1; : : : ; xn := sng 6 : = s. Hence the abstract operation is welldefined and...

Increases in rates of individual leaf photosynthesis (P n) are critical for future increases of rice yields. A previous study, using introgression lines derived from a cross between indica cultivar Habataki, with one of the highest recorded values of P n, and the Japanese elite cultivar Koshihikari, identified four QTLs (qCAR4, qCAR5, qCAR8, and qCAR11) that affect P n. The present study examin...

At the turn of the 21st century Agata Smoktunowicz constructed the first example of a nil algebra over a countable field such that the polynomial ring over the algebra is not nil. This answered an old question of Amitsur. We present a simplification of the example. Introduction This monograph began as the author’s earnest attempt to understand the beautiful example constructed in [1], and was o...

Brønsted acid promoted reversible dimerization of myrmicarin 215B leads to formation of a new heptacyclic product, isomyrmicarin 430B, that possesses a C1,C2-trans,C2,C3-trans-substituted cyclopentane ring. Mechanistic studies illustrate that isomyrmicarin 430B arises by isomerization of isomyrmicarin 430A via fragmentation to tricyclic azafulvenium ions. Factors influencing the structure of he...
