Social Networks, 2000
Abstract Networks of social relations can be represented by graphs and socio- or adjacency-matrices and their structure can be analyzed using different concepts, one of them called centrality. We will provide a new formalization of a “node-centrality” which leads to some properties a measure of centrality has to satisfy.

Centralizers and Central Idempotents of Semigroup Rings

Semigroup Forum, 2001
A ring means an associative ring (not necessarily with unity). Let \(R\) be a ring, \(A\subseteq R\). The set \(C_R(A)=\{r\in R\mid ar=ra\) for all \(a\in A\}\) is called the centralizer of \(A\) in \(R\). Let \(S\) be a semigroup, and let \(R[S]\) be the semigroup ring of \(S\) over \(R\).

CeH is about 1,000-fold more rare than primary hypothyroidism and raises several challenges for the clinicians, mainly because they cannot rely on the systematic use of the “reflex TSH strategy” for ...

Central tinnitus

Auris Nasus Larynx, 2003
Tinnitus is likely initiated by a discontinuity in the spontaneous or low-level-stimulus induced neural activity across auditory nerve fibers with different characteristic frequency (CF). This discontinuity may be caused by functional loss of outer hair cells in those regions where inner hair cells are preserved.
