Effect of altered sensory conditions on multivariate descriptors of human postural sway
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
Multivariate descriptors of sway were used to test whether altered sensory conditions result not only in changes in amount of sway but also in postural coordination. Eigenvalues and directions of eigenvectors of the ...
Semiparametric inferences for association with semi-competing risks data
(John Wiley & Sons, Ltd., 2005)
In many biomedical studies, it is of interest to assess dependence between bivariate failure time data. We focus here on a special type of such data, referred to as semi-competing risks data. In this article, we develop ...
Quadratic variation of functionals of two-parameter Wiener process
(Elsevier, 1976-12)
The quadratic variation of functionals of the two-parameter Wiener process of the form f(W(s, t)) is investigated, where W(s, t) is the standard two-parameter Wiener process and f is a function on the reals. The existence ...
Developmental changes in taste responses from glossopharyngeal nerve in sheep and comparisons with chorda tympani responses
(Elsevier, 1983-12)
To learn whether there are developmental changes in salt and acid taste responses from the posterior tongue, we recorded from the glossopharyngeal nerve, which innervates taste buds in circumvallate papillae, in sheep ...
Hyperviscous shock layers and diffusion zones: Monotonicity, spectral viscosity, and pseudospectral methods for very high order differential equations
(Kluwer Academic Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-03)
We solve two problems of x ∈[−∞, ∞] for arbitrary order j . The first is to compute shock-like solutions to the hyperdiffusion equation, u 1=(−1) j +1 u 2j,x . The second is to compute similar solutions to the stationary ...
Export Production in the Subarctic North Pacific over the Last 800 kyrs: No Evidence for Iron Fertilization?
(Kluwer Academic Publishers; The Oceanographic Society of Japan ; Springer Science+Business Media, 2004-01)
The subarctic North Pacific is a high nitrate-low chlorophyll (HNLC) region, where phytoplankton growth rates, especially those of diatoms, are enhanced when micronutrient Fe is added. Accordingly, it has been suggested ...
Influence diagnostics for the Weibull model fit to censored data
(Elsevier, 1990-01)
Methods for detecting influential observations for the Weibull model fit to censored data are discussed. These methods include: one-step deletion diagnostics, influence functions and curvature diagnostics. Results indicate ...
A generalization of the Goldman equation, including the effect of electrogenic pumps
(Elsevier, 1971-10)
An equation similar to the Goldman equation is derived for the steady-state diffusion of univalent ions across a membrane with arbitrary potential profile and in the presence of electrogenic pumps. The presence of electrogenic ...
Methods for comparing center‐specific survival outcomes using direct standardization
(Wiley, 2014-05-30)
The evaluation of center‐specific outcomes is often through survival analysis methods. Such evaluations must account for differences in the distribution of patient characteristics across centers. In the context of censored ...
