I was specifically looking for a *complete* test file that
I could run. This preamble does not help me in finding the
problem because I don't see the actual usage.

In any case, your context should not be too old.

Best, Taco

Hi Taco,

Here is the minimum tex code and the bib file. My context version is 2005.10.27. Sorry for the inconvenience.

\chapter{Introduction}
Submicron materials are now found to exhibit extreme large yield strength
as high as 10 times when compared with their bulk counterparts, which is
known as the size effect of strength. This is referred to an increase
of flow stress at some infinite strain, in terms of hardness obtained from
nanoindentation experiments\cite[Pethica, Doerner, Stelmashenko, Ma,
McElhaney, Lim, LiuNgan], or torsional strength obtained from twisting
test on small whiskers\cite[Fleck]. The explanation for this, which
has gained extensive acceptance, is the existence of strain gradient in
these deformation configurations\cite[Fleck].
