Guinea pigs of two strains, outbTed Hartley and inbred Strain 2, were immunized subcutaneously with cephalothin (CET, 20 mglbody) alone, without adjuvant. Immune responses to the antibiotic were assessed by guinea-pig passive cutaneous anaphylaxis (GP-PCA) and active systemic anaphylaxis (GP-ASA) reactions. The immune response to CET in the female Hartley guinea pigs was higher than that in the...

—Real-valued block codes are introduced, which are derived from Discrete Fourier Transforms (DFT) and Discrete Hartley Transforms (DHT). These algebraic structures are built from the eigensequences of the transforms. Generator and parity check matrices were computed for codes up to block length N=24. They can be viewed as lattices codes so the main parameters (dimension, minimal norm, area of t...

Osteoarthritis is a joint disease involved in articular cartilage, subchondral bone, meniscus and synovial membrane. This study sought to examine cartilage degeneration, subchondral bone mineral density (BMD) and meniscal mineral density (MD) in male Hartley, female Hartley and female strain 13 guinea pigs to determine the association of cartilage degeneration with subchondral BMD and meniscal ...

Model Generative Reasoning (MGR) is a problem solving architecture designed to support AI applications in unstructured task environments, i.e. in task environments in which the statistical quality, completeness, and relevance of the data that will be available to the problem solver at any particular time cannot be predicted reliably (Hartley et al., 1987; Coombs and Hartley, in press a; Coombs ...

More accurate dynamic load models get better description of the dynamic load characteristic and its relation to voltage stability. In this paper, a second order Taylor series expansion model is presented as the simplification of the popular used exponential recovery dynamic load model. Then, a frequency weighted least-squares based Hartley modulating functions (HMF) method is developed to estim...

A Fast algorithm for the Discrete Hartley Transform (DHT) is presented, which resembles radix-2 fast Fourier Transform (FFT). Although fast DHTs are already known, this new approach bring some light about the deep relationship between fast DHT algorithms and a multiplication-free fast algorithm for the Hadamard Transform. Key-words Discrete transforms, Hartley transform, Hadamard Transform.

Chicago uses Tax Increment Financing (TIF) to promote economic development to a greater extent than any other large American city. This paper conducts a comprehensive assessment of the effectiveness of Chicago’s TIF program in creating economic opportunities and catalyzing real estate investments at the neighborhood scale. This paper uses a unique panel dataset at the block group level to analy...

Research Problem Formulation. Modern financial markets are characterized by considerable complexity of the processes occurring in them. There is a globalization of international markets; currency, interest rate, rate of securities, staple prices volatility are increasing, and as a result, financial markets have become more volatile, complex and risky. An instrument of monitoring system of a sto...
