Real-Time Tracking of Non-Rigid Objects using Mean Shift
- IEEE CVPR 2000
, 2000
"... A new method for real-time tracking of non-rigid objects seen from a moving camera isproposed. The central computational module is based on the mean shift iterations and nds the most probable target position in the current frame. The dissimilarity between the target model (its color distribution) an ..."

Active Perception
, 1988
"... Active Perception (Active Vision specifically) is defined as a study of Modeling and Control strategies for perception. By modeling we mean models of sensors, processing modules and their interac-tion. We distinguish local models from global models by their extent of application in space and time. T ..."

A gene-coexpression network for global discovery of conserved genetic modules
- Science
, 2003
"... To elucidate gene function on a global scale, we identified pairs of genes that are coexpressed over 3182 DNA microarrays from humans, flies, worms, and yeast. We found 22,163 such coexpression relationships, each of which has been conserved across evolution. This conservation implies that the coexp ..."

experimentallyconfirmed the predictions implied bysome of these links and identified cell proliferation functions for several genes. By assembling these links into a gene-coexpression network, we found several components that were animal-specific as well as interrelationships between newly evolved and ancient modules

Specifying concurrent program modules.
- ACM Transactions on Programming Languages and Systems,
, 1983
"... A method for specifying program modules in a concurrent program is described. It is based upon temporal logic, but uses new kinds of temporal assertions to make the specifications simpler and easier to understand. The semantics of the specifications is described informally, and a sequence of exampl ..."

The Repetitive Oligopeptide Sequences Modulate Cytopathic Potency but Are Not Crucial for Cellular
"... The pathogenicity of Clostridium difficile is primarily linked to secretion of the intracellular acting toxins A (TcdA) and B (TcdB) which monoglucosylate and thereby inactivate Rho GTPases of host cells.

The pathogenicity of Clostridium difficile is primarily linked to secretion of the intracellular acting toxins A (TcdA) and B (TcdB) which monoglucosylate and thereby inactivate Rho GTPases of host cells. Although the molecular mode of action of TcdA and TcdB is well understood, far less is known about toxin binding and uptake. It is acknowledged that the C-terminally combined repetitive oligopeptides (CROPs) of the toxins function as receptor binding domain. The current study evaluates the role of the CROP domain with respect to functionality of TcdA and TcdB. Therefore, we generated truncated TcdA devoid of the CROPs (TcdA 1–1874) and found that this mutant was still cytopathic. However, TcdA 1–1874 possesses about 5 to 10-fold less potency towards 3T3 and HT29 cells compared to the full length toxin. Interestingly, CHO-C6 cells even showed almost identical susceptibility towards truncated and full length TcdA concerning Rac1 glucosylation or cell rounding, respectively. FACS and Western blot analyses elucidated these differences and revealed a correlation between CROP-binding to the cell surface and toxin potency. These findings refute the accepted opinion of solely CROP- mediated toxin internalization. Competition experiments demonstrated that presence neither of TcdA CROPs nor of full length TcdA reduced binding of truncated TcdA 1–1874 to HT29 cells. We assume that toxin uptake might additionally occur through alternative receptor structures and/or other associated endocytotic pathways. The second assumption was substantiated by TER measurements showing that basolaterally applied TcdA 1–1874 exhibits considerably higher cytotoxic potency than
Response element sequence modulates estrogen receptor alpha and beta affinity and activity

"... The relationship between estrogen receptor (ER)–estrogen response element (ERE) binding affinity and estradiol (E2)-induced transcription has not been systematically or quantitatively tested. We examined the influence of ERE palindrome length and the 3 ′ ERE flanking sequence on ERα and ERβ affinity ..."

Intronic and exonic sequences modulate 5 ′ splice site selection in plant nuclei
, 1996
"... Pre-mRNA transcripts in a variety of organisms, including plants, Drosophila and Caenorhabiditis elegans, contain introns which are significantly richer in adenosine and uridine residues than their flanking exons. Previous analyses using exonic and intronic replacements between two nonequivalent 5 ′ ..."

AU-rich sequences function by promoting recognition of the most upstream 5 ′ splice site rather than by masking the downstream 5 ′ splice site. Sequence insertions define a role for AG-rich exonic sequences in plant pre-mRNA splicing by demonstrating that an AG-rich element is capable of promoting
