Statistics for the Clinician: Diagnostic Questionnaires

The goal of this column is to help working clinicians understand the statistical calculations involved in interpreting the results of diagnostic questionnaires. Using the Patient Health Questionnaire-9 as an example, the author explains how to determine th ...

Local control theory in trajectory-based nonadiabatic dynamics

Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Thomas James Penfold

In this paper, we extend the implementation of nonadiabatic molecular dynamics within the framework of time-dependent density-functional theory in an external field described in Tavernelli et al. [Phys. Rev. A 81, 052508 (2010)] by calculating on-the-fly p ...

Incremental Identification of Reaction and Mass-Transfer Rates In Gas-Liquid Reaction Systems Using Tendency Modeling

Dominique Bonvin, Nirav Pravinbhai Bhatt

The identification of reliable reaction and mass-transfer rates is important for building first-principles models of gas-liquid reaction systems. The identification of these rates involves the determination of a model structure (reaction stoichiometry, rat ...

The conventional CAD/CAM approach to design does not show the essential spatial relationships between user and product that are crucial for intuitive design analysis. As populations age and the home appliance market stagnates, Universal Design principles i ...

Experiences in measuring a human contact network for epidemiology research

Marcel Salathé

This paper discusses our experience in designing and deploying a 994-node sensor network to measure the social contact network of a high school over one typical day. The system aims to capture interactions of human subjects for the study of infectious dise ...

Evolution in heterogeneous populations From migration models to fixation probabilities

Séverine Vuilleumier Varisco, Nicolas Perrin

Although dispersal is recognized as a key issue in several fields of population biology (such as behavioral ecology population genetics metapopulation dynamics or evolutionary modeling) these disciplines focus on different aspects of the concept and often ...

Femtosecond XANES Study of the Light-Induced Spin Crossover Dynamics in an Iron(II) Complex

Majed Chergui, Paul Beaud, Wojciech Gawelda, Camelia Borca, Van Thai Pham, Renske Marjan van der Veen

X-ray absorption spectroscopy is a powerful probe of mol. structure, but it has previously been too slow to track the earliest dynamics after photoexcitation. We investigated the ultrafast formation of the lowest quintet state of aq. iron(II) tris(bipyridi ...

Villes à la frontière et transformation de l'espace

Lena Poschet El Moudden

Few borders exist which separate two countries as dramatically disparate as the Dominican Republic and Haiti. Both share the territory of the Hispaniola island, but a profound process of differentiation rooted in the colonial division of the island between ...

Vibrational coherence and solvent-induced non-adiabatic couplings

Majed Chergui

The ultrafast non-radiative relaxation processes between electronic states of Hg2 trapped in a cryogenic argon matrix after photon excitation at 266 nm is studied by mol. dynamics with quantum transitions (MDQT). Population transfer by matrix-induced coupl ...

Métropolisation, habitat précaire et relogement forcé: entre phénomènes d'exclusion et tactiques populaires d'intégration

Sébastien Wust

This work was carried out within the interdisciplinary scientific program named "Sustainable Development, Metropolisation and Pollution of Natural Resources in Ho Chi Minh-City, Vietnam". This program, launched in 1994, is financed by the Swiss National Sc ...
