In this work, we present techniques that aim at physically detaching the graphical user interface (GUI) from digital content that is displayed on a tabletop. For this purpose, we extended a pen-enabled tabletop with several spatially aware (6DOF) paper-like mobile displays. In contrast to previous work, we provide a fully dynamic solution. This means the(More)
Approximately 438 pb −1 of e + e − data from the OPAL detector, taken with the LEP collider running at centre-of-mass energies of 192-209 GeV, are analyzed to search for evidence of chargino pair production, e + e − → ˜ χ + 1 ˜ χ − 1 , or neutralino associated production, e + e − → ˜ χ 0 2 ˜ χ 0 1. Limits are set at the 95% confidence level on the product(More)
Searches for the neutral Higgs bosons h 0 and A 0 are used to obtain limits on the Type II Two Higgs Doublet Model (2HDM(II)) with no CP–violation in the Higgs sector and no additional particles besides the five Higgs bosons. The analysis combines approximately 170 pb −1 of data collected with the OPAL detector at √ s ≈ 189 GeV with previous runs at √ s ≈ m(More)
Cross-sections and angular distributions for hadronic and lepton pair final states in e + e − collisions at a centre-of-mass energy near 189 GeV, measured with the OPAL detector at LEP, are presented and compared with the predictions of the Standard Model. The results are used to measure the energy dependence of the electromagnetic coupling constant α em ,(More)
The measurement of small–angle Bhabha scattering is used to determine the luminosity at the OPAL interaction point for the LEP I data recorded between 1993 and 1995. The measurement is based on the OPAL Silicon-Tungsten Luminometer which is composed of two calorimeters encircling the LEP beam pipe, on opposite sides of the interaction point. The luminometer(More)
BACKGROUND We were able to demonstrate a predictive value of serum HER2 (sHER2) in patients receiving trastuzumab in the neoadjuvant GeparQuattro trial. However, the role of sHER2 in patients receiving neoadjuvant therapy (NT) with lapatinib is still unclear. METHODS The neoadjuvant GeparQuinto trial compared trastuzumab vs lapatinib in addition to(More)
A search for pair produced scalar fermions with couplings that violate R-parity has been performed using a data sample corresponding to an integrated luminosity of 56 pb −1 at a centre-of-mass energy of √ s = 183 GeV collected with the OPAL detector at LEP. An important consequence of R-parity breaking interactions is that the lightest supersymmet-ric(More)
Production of events with hadronic and leptonic final states has been measured in e + e − collisions at centre-of-mass energies of 130–172 GeV, using the OPAL detector at LEP. Cross-sections and leptonic forward-backward asymmetries are presented, both including and excluding the dominant production of radiative Zγ events, and compared to Standard Model(More)
In these demonstrations, we present novel uses for tangible magic lenses, i.e., spatially aware lightweight displays that can be moved through the physical 3D space on or above a tabletop. In the first demo, we demonstrate the usefulness of tangible views to support interaction with information visualizations, such as graph, matrix, and space-time-cube(More)
Searches for a scalar top quark and a scalar bottom quark have been performed using a data sample of 438 pb −1 at centre-of-mass energies of √ s =192 – 209 GeV collected with the OPAL detector at LEP. No evidence for a signal was found. The 95% confidence level lower limit on the scalar top quark mass is 97.6 GeV if the mixing angle between the(More)
