This paper studies capital adjustment costs. Our goal here is to characterize these adjustment costs, which are important for understanding both the dynamics of aggregate investment and the impact of various policies on capital accumulation. Our estimation strategy searches for parameters that minimize ex post errors in an Euler equation. This strategy is quite common in models for which adjust...

PURPOSE The aim of this study was to combine a set of methods for use of radiochromic film dosimetry, including calibration, correction for lateral effects and a proposed triple-channel analysis. These methods can be applied to GAFCHROMIC EBT3 film dosimetry for radiation field analysis and verification of IMRT plans. METHODS A single-film exposure was used to achieve dose calibration, and th...

In the 1980’s, Belavin and Drinfeld classified non-unitary solutions of the classical Yang-Baxter equation (CYBE) for simple Lie algebras [1]. They proved that all such solutions fall into finitely many continuous families and introduced combinatorial objects to label these families, Belavin-Drinfeld triples. In 1993, Gerstenhaber, Giaquinto, and Schack attempted to quantize such solutions for ...

In this paper I intend to contrast the ‘falling rate of profit’ crisis theories of the 1970s with the ‘underconsumptionism’ of the orthodox Marxist tradition. The central argument is that in rejecting traditional underconsumptionist theories of crisis contemporary Marxism has thrown the baby out with the bathwater, with unfortunate theoretical and political consequences. A more adequate critiqu...

Attachment of a nondiffusible bromoacetyl electrophile to the 5-position of a thymine at the 5'-end of a pyrimidine oligodeoxyribonucleotide affords sequence-specific alkylation of a guanine base in duplex DNA two base pairs to the 5'-side of a local triple-helical complex. Products resulting from reaction of 5'-ETTTTMeCTTTTMeCMeCTTTMeCTTTT-3' at 37 degrees C with a 29 base pair target duplex a...

BACKGROUND With the wide use of antibiotics, antibiotic-resistant Helicobacter pylori strains are becoming increasingly prevalent. It has been hypothesized that culture-guided therapy might help to increase treatment success. But the effects and the costs still remain controversial. AIMS To systematically review the efficacy and the cost of culture-guided triple therapy, compared to standard ...
