Fahrstuhlfahrten und Einstiegsschwierigkeiten:Erschließungstechniken in Georges Perecs "La Vie mode d’emploi"
Der Artikel ist eine produktionsästhetische Untersuchung zu Einstiegsschwierigkeiten in literarische Schreibprozesse und ihre Auflösung mithilfe räumlicher und sprachspielerischer Erschließungstechniken. Als Beispiel dient mir die Poetik des OuLiPo (»Ouvroir de littérature potentielle«) und hier insbesondere (die Genese von) Georges Perecs Roman »La vie mode d’emploi«. Genauer wird daran gezeigt, wie Perec eine blockierte Fahrstuhlfahrt als metaphorische Referenz auf seine anfängliche Schreibhemmung in den Roman einfügt und wie diese Referenz als Kommentar zur Erzählbarkeit komplexer Raum-Zeit-Gefüge im Gesellschaftsroman des 20. Jahrhunderts, insbesondere zu Marcel Prousts »Recherche«, verstanden werden kann
Intermediale Bezugnahme und mediale Materialität
In ihrer Replik auf den Beitrag von Beatrice Nickel weitet Johanne Mohs die Perspektive auf ›Gedichtobjekte‹ im städtischen Raum nach 1945 aus. Eingangs differenziert sie den Begriff der Intermedialität, um daraufhin die von Beatrice Nickel angeführten Beispiele analytisch zu spezifizieren und interpretatorisch zu vertiefen. Letztlich folgt ihre Lesart den Avantgardekonzepten des frühen 20. Jahrhunderts, um das von den Künstlern problematisierte Wechselverhältnis von ›Kunst‹ und ›Leben‹ zu beleuchten
Particle production and equilibrium properties within a new hadron transport approach for heavy-ion collisions
The microscopic description of heavy-ion reactions at low beam energies is
achieved within hadronic transport approaches. In this article a new approach
SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) is introduced
and applied to study the production of non-strange particles in heavy-ion
reactions at GeV. First, the model is described including
details about the collision criterion, the initial conditions and the resonance
formation and decays. To validate the approach, equilibrium properties such as
detailed balance are presented and the results are compared to experimental
data for elementary cross sections. Finally results for pion and proton
production in C+C and Au+Au collisions is confronted with HADES and FOPI data.
Predictions for particle production in collisions are made.Comment: 30 pages, 30 figures, replaced with published version; only minor

Fluorescent Sensor Arrays Can Predict and Quantify the Composition of Multicomponent Bacterial Samples
Fast and reliable identification of infectious disease agents is among the most important challenges for the healthcare system. The discrimination of individual components of mixed infections represents a particularly difficult task. In the current study we further expand the functionality of a ratiometric sensor array technology based on small-molecule environmentally-sensitive organic dyes, which can be successfully applied for the analysis of mixed bacterial samples. Using pattern recognition methods and data from pure bacterial species, we demonstrate that this approach can be used to quantify the composition of mixtures, as well as to predict their components with the accuracy of ~80% without the need to acquire additional reference data. The described approach significantly expands the functionality of sensor arrays and provides important insights into data processing for the analysis of other complex samples
Particle production and equilibrium properties within a new hadron transport approach for heavy-ion collisions
The microscopic description of heavy-ion reactions at low beam energies is achieved within hadronic transport approaches. In this article a new approach called "Simulating Many Accelerated Strongly interacting Hadrons" (SMASH) is introduced and applied to study the production of nonstrange particles in heavy-ion reactions at Ekin=0.4A-2A GeV. First, the model is described including details about the collision criterion, the initial conditions and the resonance formation and decays. To validate the approach, equilibrium properties such as detailed balance are presented and the results are compared to experimental data for elementary cross sections. Finally results for pion and proton production in C+C and Au+Au collisions is confronted with data from the high-acceptance dielectron spectrometer (HADES) and FOPI. Predictions for particle production in π+A collisions are made
Cognitive Impairment Precedes and Predicts Functional Impairment in Mild Alzheimer’s Disease
Abstract
Background: The temporal relationship of cognitive deficit and functional impairment in Alzheimer’s disease (AD) is not well characterized. Recent analyses suggest cognitive decline predicts subsequent functional decline throughout AD progression.
Objective: To better understand the relationship between cognitive and functional decline in mild AD using autoregressive cross-lagged (ARCL) panel analyses in several clinical trials.
Methods: Data included placebo patients with mild AD pooled from two multicenter, double-blind, Phase 3 solanezumab (EXPEDITION/2) or semagacestat (IDENTITY/2) studies, and from AD patients participating in the Alzheimer’s Disease Neuroimaging Initiative (ADNI). Cognitive and functional outcomes were assessed using AD Assessment Scale-Cognitive subscale (ADAS-Cog), AD Cooperative Study-Activities of Daily Living instrumental subscale (ADCS-iADL), or Functional Activities Questionnaire (FAQ), respectively. ARCL panel analyses evaluated relationships between cognitive and functional impairment over time.
Results: In EXPEDITION, ARCL panel analyses demonstrated cognitive scores significantly predicted future functional impairment at 5 of 6 time points, while functional scores predicted subsequent cognitive scores in only 1 of 6 time points. Data from IDENTITY and ADNI programs yielded consistent results whereby cognition predicted subsequent function, but not vice-versa.
Conclusions: Analyses from three databases indicated cognitive decline precedes and predicts subsequent functional decline in mild AD dementia, consistent with previously proposed hypotheses, and corroborate recent publications using similar methodologies. Cognitive impairment may be used as a predictor of future functional impairment in mild AD dementia and can be considered a critical target for prevention strategies to limit future functional decline in the dementia process
The future is now: Model-based clinical trial design for Alzheimer's disease
Failures in trials for Alzheimer's disease (AD) may be attributable to inadequate dosing, population selection, drug inefficacy, or insufficient design optimization. The Coalition Against Major Diseases (CAMD) was formed in 2008 to develop drug development tools (DDT) to expedite drug development for AD and Parkinson's disease.1 CAMD led a process that successfully advanced a clinical trial simulation (CTS) tool for AD through the formal regulatory review process at the US Food and Drug Administration (FDA) and European Medicines Agency (EMA)
