Seventeen strains of viruses isolated in Africa and South America, all of them neurotropic for Swiss mice, were submitted to immunological investigation by means of cross-neutralization tests, along with a group of 12 previously known viruses having ...

Abstract The paper is concerned with tests for Granger causality and for cointegration between (log) money and (log) output in Germany. Augmented Dickey—Fuller tests show that only second differences of both variables are stationary and only first differences (and not levels) are cointegrated. Furthermore it is shown that there is most times feedback

The platelet neutralization test is used in the laboratorvy diagnosis of the lupus anticoagulant (Laffan and Manning, Dacie and Lewis practical haematology. Churchill Livingstone, Philadelphia, PA, pp 445-446, 2006). The lupus anticoagulant typically causes prolongation of phospholipid-dependent coagulation tests such as APTT, DRVVT, etc.

Testing the generalized neutrality hypothesis
Theoretical Population Biology, 1979Abstract Various tests of the hypothesis of selective neutrality based on gene frequency are now available. These tests take as null hypothesis the concept of “strict neutrality”: all new mutants are required to be selectively identical to each other.

Standardization of Poliovirus Neutralizing Antibody Tests
Clinical Infectious Diseases, 1984Recently the Forum for Advancement of Immunization Research sponsored a Collaborative Study on Poliovirus Antibody Titration. Twenty laboratories from 12 countries participated. There were considerable differences in detail of test performance and test results among laboratories.

Tests for the structure of the neutral current
Physical Review D, 1977The isospin and V,A structure of the weak neutral current may be determined from a study of the charge distribution of pions in neutrino and antineutrino reactions. Qualitative and quantitative relations are presented which are independent of any dynamical models.

A reexamination of Mishkin's neutrality test
Journal of Economics and Business, 1995Abstract Mishkin's 1982 paper is one of the most widely cited papers in empirical macroeconomics. His finding that anticipated money growth is not neutral in the US casts doubt on the policy ineffectiveness proposition. However, recent advances in econometrics suggest that Mishkin's model may be misspecified, thus raising questions concerning his ...

An indirect enzyme-linked immunosorbent assay (ELISA) for the detection of serum antibody to bovine respiratory syncytial virus (BRSV) was developed and compared with complement-fixation (CF) and viral neutralization (VN) tests.

A neutral sampling formula for multiple samples and an ‘exact’ test of neutrality
Ecology Letters, 2007AbstractAs the utility of the neutral theory of biodiversity is increasingly being recognized, there is also an increasing need for proper tools to evaluate the relative importance of neutral processes (dispersal limitation and stochasticity). One of the key features of neutral theory is its close link to data: sampling formulas, giving the probability

Abstract This paper derives and implements a robust test of the short-run neutrality of anticipated policy that is valid when the information set used to form expectations is incorrectly specified and the effect of unanticipated policy on deviations of output from the natural rate varies over time.
