It is with great sadness that we say goodbye to Marcy Carlson Speer, who died on August 4, 2007, at the age of 47 after a two-year battle with breast cancer. Marcy was an extremely accomplished scientist who, at the time of her death, was the director of the Duke Center for Human Genetics and chief of the Division of Medical Genetics. During her career, she published 124 articles and 16 book ch...

We propose a generalized ordered response model that nests the popular Carlson-Parkin (CP) method to quantify household inflation expectations while explicitly control for cross-sectional heterogeneity in the threshold parameters and the variance. By matching qualitative and quantitative data from 1979 to 2012 from the University of Michigan’s Survey of Consumers, we find evidence against the t...

1. General setting Let T be a nonempty set, Σ be the σ -algebra of subsets of T , and μ be a nonnegative σ -additive measure on Σ . We denote by Lp(T , Σ, μ) (or simply Lp(T , μ)) the set of all Σ-measurable functions with values in R or in C for which ∥x(·)∥Lp(T ,μ) =  T |x(t)|p dμ(t) 1/p < ∞, 1 ≤ p < ∞, ∥x(·)∥L∞(T ,μ) = ess sup t∈T |x(t)| < ∞, p = ∞. Put W = {x(·) ∈ Lp(T , μ) : ∥φ(·)x(·)∥L...

The sheaths that invest the nerves of amphibia, insects and freshwater clams differ in structure. Previous studies have shown, though, that the nerves of all these animals have in common the ability to function for extended periods in sodium-free solutions (Krnjevid, 1954; Twarog & Roeder, 1956; Carlson & Treherne, 1969). In amphibia and insects, it has been shown that this capacity is lost if ...

Generics are sentences such as “tigers are striped,” “lions have manes,” and “mosquitoes carry West Nile virus.” Generics express generalizations, but unlike quantified statements, generics do not carry information about howmany members of the kind or category have the property. For example, if asked “how many ravens are black?” one could reply “all [or some, or most, etc] ravens are black,” bu...

Smalley (1965) demonstrated that the adult firefly lantern can be classified as adrenergic with respect to a number of criteria established for vertebrate sympathetic junctions. The lantern luminesces in response to adrenaline and its analogues. Amphetamine acts indirectly to induce luminescence and fails in denervated lanterns. Reserpinized lanterns respond to adrenaline, but no longer to neur...

We have been accustomed to estimate the lactate in blood by hemolysis in water, removal of the proteins by the method of Folin and Wu (4), treatment of the filtrate with CuSO4 and Ca(OH)2 according to Van Slyke (ll), and estimation of the lactate in the centrifugate by a modification of the aeration method of Friedemann, Cotonio, and Shaffer (6). There have been suggestions that some of the pre...

Lactic acid is a substance of major significance throughout the orders of life, from microbe to man. Its relation to the carbohydrate metabolism has been very extensively st,udied; and it is not surprising, therefore, that many methods have been proposed for its quantitative estimation. Most of the methods depend upon the conversion of lactic acid into acetaldehyde (1, 2), the latter being dete...

In this paper, a new current mode fractional order filter is presented using multi-mode second generation controlled conveyors (MO-CCCII).in method consists of two resistors and grounded capacitors 3MO-CCCII. This accomplished with fractional-order capacitor, also known as stationary phase element, to form filter. The proposed designed 0.2, 0.4 orders. capacitor was obtained reduced integer-ord...
