1 We study the properties of a test of that determines whether two time series co-move. The test computes a simple non-parametric statistic for " concordance, " which describes the proportion of time that the cycles of two series spend in the same phase. We establish the size and power properties of this test. As an illustration, the procedures are applied(More)
INTRODUCTION Nasoalveolar molding (NAM) is a treatment option available for early cleft care. Despite the growing debate about the efficacy of nasoalveolar molding, questions remain regarding its prevalence and the demographic characteristics of families undergoing this technique prior to traditional cleft surgery. OBJECTIVES To determine the number of(More)

OBJECTIVES Having observed variation in the breadth of surgeons' fingers whilst they are placing the incision for submandibular gland surgery, we aimed to examine this technique of incision siting, quantify the differences in fingerbreadths and consider any consequences of variability. METHODS Surgeons trained in salivary gland surgery were questioned on(More)
1. The hydrolytic activity of IgG purified from (a) 13 samples of ovine antiserum collected from three animals during a two-year immunisation programme using a phosphate immunogen (comprising the amide conjugate bonded through the carboxy group of 4-nitrophenyl 4-carboxymethylphenyl hydrogen phosphate and amino groups of keyhole-limpet haemocyanin) and (b)(More)
Hecogenin has been transformed into [11,11,12,12-2H4]progesterone via base-catalyzed isotope exchange with D2O (at C-11), carbenic decomposition of the 12-tosylhydrazone formed by the use of [N,N,N'-2H3]toluene-p-sulfonylhydrazine, and reduction with [2H2]diimide to give [11,11,12,12-2H4]tigogenin, followed by standard degradation of the spiroketal side(More)
Various papers have identified shocks to investment as major drivers of output, investment , hours, and interest rates. Justiniano et al. (2011) heuristically link these investment shocks to financial frictions because financial markets are instrumental in transforming consumption goods into installed capital. However, the importance of investment shocks is(More)
