By analyzing time-activity curves over selected brain regions, following intravenous administration of a non-diffusible radionuclide, it is possible to assess regional arm-brain mean transit time (rABmtT). By evaluating this parameter in normal subjects a relatively small range of differences between symmetrical regions can be found (030 ± 0.14 sec, mean ± SD). An increase of this difference ab...

The asymmetric unit of the title compound, C23H23N3, consists of two mol-ecules, A and B, with different conformations. In mol-ecule A, the dihedral angle between the carbazole ring system (r.m.s. deviation = 0.028 Å) and the pyridine ring is 20.28 (9)° and the N-C-C-C torsion angle of the butyl side chain is -63.4 (3)°. The equivalent data for mol-ecule B are 0.065 Å, 48.28 (11)° and 61.0 (3)°...

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable. Moreover, the present model exhibits a 'supercritical pitchfork bifurcation' rather than the 'subcritical pitchfork bifurcation' of the CP model. This may be a better...

6 International Conference TABLEAUX’97 – Short Papers, Technical Report CRIN 97-R-030, Université de Nancy II, 1997 Abstract. We present a refutation system for intuitionistic logic which allows to locate situations where constructive reasoning is unnecessary. In many subgoals of a derivation this property makes it possible to reduce the set of relevant reduction rules to a confluent one. As a ...

We examine the dynamic properties of an endogenous growth model with an explicit R&D sector in order to evaluate its ability to propagate temporary disturbances into persistent fluctuations in macroeconomic variables. We demonstrate that a large proportion of the variability and persistence of measured Solow residuals can be thought of as reflecting the endogenous accumulation and adaptation of...
