Human–machine-interaction studies complex communication and interaction principles between people and computers. HMI research is concerned with a wide field of related topcis covering the realisation, evaluation of interactive machine and computing systems. It furthermore covers knowledge representation, displaying techniques, signal processing, pattern recognition, human factors, haptics and r...

The University of Osnabrück is proud of hosting the KI conference for the first time. The University’s teaching and research profile is shaped by a number of interdisciplinary institutes and study courses, of which Cognitive Science is prominent since quite some time. AI research and education is also visibly present in its young Informatics institute. The KI 2007 technical program comprises si...

Given integers {gi ≥ 2}ni=1 we prove that there exists infinitely may knots Ki ⊂ S so that g(E(Ki)) = gi and g(E(# i=1 Ki) = Σ n i=1 g(E(Ki)). (Here, E(·) denotes the exterior and g(·) the Heegaard genus.) Together with [8, Theorem 1.5], this proves the existence of counterexamples to Morimoto’s Conjecture [14].

Two flat revertants have been isolated from mutagen-treated populations of Kirsten murine sarcoma virus (Ki-MuSV)-transformed NIH/3T3 cells. These revertants, which appear to be cellular variants resistant to transformation by the Ki-MuSV oncogene v-Ki-ras, contain Ki-MuSV-specific DNA, elevated levels of the v-Ki-ras gene product p21, and rescuable transforming virus. Cell hybridization studie...

Povzetek. Ena ključnih lastnosti ogrodnih sistemov je, da temeljijo na standardih, ki omogočajo globalno medobratovalnost storitvenih infrastruktur. Tako je večina današnjih ogrodij zasnovana na specifikacijah Web Services Resource Framework (WSRF), ki so trenutno najpomembnejši standard na tem področju. Omenjene specifikacije skupaj s še nekaterimi specifikacijami iz sklada spletnih storitev d...

Ki-67 is one of the most useful markers to evaluate cell proliferative activity and has been widely used in tumor treatment and research. However, its role in human laryngeal carcinoma remains poorly defined. The aim of the present study was to investigate the expression of Ki-67 in human laryngeal squamous carcinoma and the effect of Ki-67 gene silencing by small interfering (si)RNA on the pro...

BACKGROUND Ki-67 is an established marker of cell proliferation, and the Ki-67 index correlates with the clinical course of several cancer types, including bladder cancer (BC). However, the clinicopathological and prognostic significance of Ki-67 in bladder cancer remains unclear. Therefore, we performed a systematic review and meta-analysis to clarify this relationship. METHODS A comprehensi...

The aim of the present study was to identify the optimal Ki-67 cut-off value in breast cancer (BC) patients, and investigate the association of Ki-67 expression levels with other prognostic factors. Firstly, a retrospective search was performed to identify patients with stage I-III BC (n=462). A range of Ki-67 index values were then assigned to five groups (<10, 10-14, 15-19, 20-24 and ≥25%). T...

Let (Xi, Bi, mi) (i ∈ N) be a sequence of Borel measure spaces. There is a Borel measure μ on ∏ i∈N Xi such that if Ki ⊆ Xi is compact for all i ∈ N and ∏ i∈N mi(Ki) converges then μ( ∏ i∈N Ki) = ∏ i∈N mi(Ki)

Based on the existence of choline acetyltransferase and acetylcholine in human placenta, we have investigated the presence of muscarinic acetylcholine receptors in brush-border and basal plasma membranes from human term placenta. Radioligand binding assay, using [3H]N-methyl-scopolamine as tracer, showed the existence of acetylcholine muscarinic receptors in brush-border (Kd 0.28 +/- 0.04 nM; B...
