Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC
(2012)Physics Letters BResults are presented from searches for the standard model Higgs boson in proton–proton collisions at √s = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 fb−1 at 7 TeV and 5.3 fb−1 at 8 TeV. The search is performed in five decay modes: γγ, ZZ, W+W−, τ+τ−, and bb. An excess of events is observed above the expected background, with a local significance ...Journal Article -
Nonequilibrium thermodynamics: a powerful tool for scientists and engineers
(2012)DYNAWe present the two-generator framework of nonequilibrium thermodynamics with a strong emphasis on fundamental notions rather than mathematical details. The underlying statistical mechanics and the implications for thermodynamically guided simulation techniques are sketched briefly. The usefulness and maturity of the framework are illustrated by reviewing a large number of recent far-from-equilibrium applications, where nonlinearity ...Journal Article -
Search for large extra dimensions in dimuon and dielectron events in pp collisions at root s=7 TeV
(2012)Physics Letters BResults are presented from a search for large, extra spatial dimensions in events with either two isolated muons or two isolated electrons. The data are from proton–proton interactions at √s=7TeV collected with the CMS detector at the LHC. The size of the data sample corresponds to an integrated luminosity of approximately 2fb-1 . The observed dimuon and dielectron mass spectra are found to be consistent with standard-model expectations. ...Journal Article -
Search for heavy, top-like quark pair production in the dilepton final state in pp collisions at √s=7 TeV
(2012)Physics Letters BThe results of a search for pair production of a heavy, top-like quark, t ', in the decay mode t't-'→bW+b-W-→bℓ+νb-ℓ-ν- are presented. The search is performed with a data sample corresponding to an integrated luminosity of 5.0fb -1 in pp collisions at a center-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC. The observed number of events agrees with the expectation from standard model processes, and no evidence of t't-' ...Journal Article -
Effort-reward and work-life imbalance, general stress and burnout among employees of a large public hospital in Switzerland
(2012)Swiss Medical WeeklyINTRODUCTION: Effort-reward imbalance (ERI) and work-life imbalance (WLI) are recognised risk factors for work stress and burnout but have not been investigated conjointly so far and compared with each other in this regard. The present cross-sectional study provides initial evidence by studying associations of ERI and WLI with general stress and burnout simultaneously. METHODS: The study was based on survey data collected in 2007 among ...Journal Article -
Neuroenhancement - perspectives of Swiss psychiatrists and general practitioners
(2012)Swiss Medical WeeklyQUESTIONS UNDER STUDY: Although the ethical and health implications of neuroenhancement have been intensely discussed over the past years, little is known about the experiences and attitudes of physicians confronted with requests for neuroenhancing substances. The aim of this study was to explore general practitioners’ and psychiatrists’ familiarity with such requests and their willingness to prescribe these products. METHOD: A nation-wide ...Journal Article -
Urban Physics: Effect of the micro-climate on comfort, health and energy demand
(2012)Frontiers of Architectural ResearchThe global trend towards urbanisation explains the growing interest in the study of the modification of the urban climate due to the heat island effect and global warming, and its impact on energy use of buildings. Also urban comfort, health and durability, referring respectively to pedestrian wind/thermal comfort, pollutant dispersion and wind-driven rain are of interest. Urban Physics is a well-established discipline, incorporating ...Journal Article -
Planning meets self-organization: Integrating interactive evolutionary computation with cellular automata for urban planning
(2012)Frontiers of Architectural ResearchThe experiment carried by the author in 2010 is to test if self-organizing systems could be systematically regulated according to the user's preference for global behavior. Self-organizing has been appreciated by architects and urban planners for its richness in the emerging global behaviors; however, design and self-organizing are contradictory in principle. It seems that it is inevitable to balance the design and self-organization if ...Journal Article -
The optimization of architectural shape based on Genetic Algorithm
(2012)Frontiers of Architectural ResearchGenetic Algorithm (GA) is widely adopted in optimization and the improvement of its optimization performance is attracting many researchers’ attentions. In solving practical problems in the process of architectural design, the ways of converting design problems into mathematical models that can be addressed by GA are of great significance in achieving final optimal results. However, no such rule that can be applied to such conversion has ...Journal Article -
The impact of ellipsoidal particle shape on pebble breakage in gravel
(2012)International Journal of Rock Mechanics and Mining SciencesWe have studied the influence of particle shape and consequently loading configuration on the breakage load of fluvial pebbles. Unfortunately, physical strength tests on pebbles, i.e., point-load tests, can only be conducted under one specific stable loading configuration. Therefore, the physical uniaxial strength tests performed in this study were extended by a two-dimensional finite-element stress analysis, which is capable of investigating ...Journal Article
