  2. 1. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving

    Author : Lena Smidfelt-Rosqvist; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic calming; intersections; driving adaptation; speed limits; Road transport technology; driving behaviour; Vägtransportteknik; overall effects; trip-long; non-local effects;

    Abstract : The planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. READ MORE

  4. 2. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections

    Author : Anna Falk Delgado; Elna-Marie Larsson; Anja Smits; Jens Sörensen; John Hald; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiologi; Radiology;

    Abstract : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. READ MORE

  5. 3. Mind off driving: Effects of cognitive load on driver glance behaviour and response times

    Author : Emma Nilsson; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cognitive load; visual behaviour; lead vehicle braking; traffic safety; distraction; response times; driver behaviour; intersections;

    Abstract : Introduction: Safe driving requires drivers to look at relevant information in the traffic environment and react in time in case a critical event arises. Concerns exist that cognitively loading tasks might interfere with drivers’ abilities to do this. READ MORE

  6. 4. Non-linear Spectroscopy of Conical Intersections with XUV and X-ray Photons

    Author : Deependra Jadoun; Markus Kowalewski; Faris Gelmukhanov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conical Intersections; Non-linear Spectroscopy; Quantum Dynamics; Perturbation Theory; Ultrafast Spectroscopy; X-ray; XUV; Theoretical Physics; teoretisk fysik;

    Abstract : Conical intersections (CIs) appear in a molecule due to the breakdown of the Born-Oppenheimer approximation when the energy difference between two or more electronic states decreases. CIs are known to play a crucial role in processes such as photosynthesis and vision in the human eye, and therefore it is important to probe the existence of such entities in molecules. READ MORE

  7. 5. Intersections on moduli spaces of curves

    Author : Sergei Shadrin; Torsten Ekedahl; Carel Faber; Stockholms universitet; []
    Keywords : Mathematics;

    Abstract : We present a new approach to perform calculations with the certain standard classes in cohomology of the moduli spaces of curves. It is based on an important lemma of Ionel relating the intersection theoriy of the moduli space of curves and that of the space of admissible coverings. READ MORE
