(1) zd = { i √ d 2 if d ≡ 0 (mod 4), −1+i √ d 2 if d ≡ 3 (mod 4). The j-function has the remarkable property that j(zd) is an algebraic integer of degree h(−d), the class number of K = Q(zd). In fact, K(j(zd)) is the Hilbert class field of K [4]. The first few values of j(zd) are: j(z3) = 0, j(z4) = 12 , j(z7) = −153, j(z8) = 20, j(z11) = −323 j(z15) = −191025−85995√5 2 , j(z19) = −963, j(z20) ...

When scientists choose research projects with the highest expected value an externality can appear; slight variations on existing work will be selected in preference to new lines of research that would ultimately generate more value. New research enjoys two advantages: it is riskier and hence more likely to lead to high-value spin-o¤ projects and it can generate more spin-o¤ projects. Less comm...

Small angle x-ray scattering and viscometric analyses of the alpha-zeins of maize in solution indicated that the molecules were asymmetric. Structure predictions of consensus sequences for the two classes of alpha-zeins, Z19 and Z22, were in good agreement with the alpha-helical contents determined by circular dichroism. Dimensions determined by small angle x-ray scattering and viscometry indic...

When scientists choose research projects with the highest expected value an externality can appear; slight variations on existing work will be selected in preference to new lines of research that would ultimately generate more value. New research enjoys two advantages: it is riskier and hence more likely to lead to high-value follow-up projects and it can generate more follow-up projects. Less ...

The B-hordeins are the major group of prolamin storage proteins in barley (Hordeum vulgare L.) and they are encoded by a small multigene family that is expressed specifically in the developing endosperm. We report the complete nucleotide sequence of a clone of one B-hordein gene (pBHR184). The cloned gene contains no introns and belongs to the B1 sub-family of B-hordein genes. Comparison of the...

We investigate the role of externalities in tax evasion arising from congestion of the auditing resources available to local tax authorities. The empirical analysis employs a novel method due to Graham (2008) that mitigates most of the problems that surround the identification of endogenous social effects [Manski (1993)]. Identification exploits the information contained in the variance of conc...

We construct a measure of gubernatorial candidates’ personal appeal by showing 10-second, silent video clips of unfamiliar gubernatorial debates to a group of experimental participants and asking them to predict the election outcomes. The participants’ predictions explain more than 20 percent of the variation in the actual two-party vote share across the 58 elections in our study, and their imp...

Agrin is an extracellular matrix protein that mediates the nerve-induced clustering of nicotinic acetylcholine receptors on target muscle cells, and thus plays a key role in development of the neuromuscular synapse. Alternative exon usage within the rat agrin gene predicts numerous protein isoforms, which differ by the inclusion or exclusion of small inserts at three sites in the C-terminal hal...
