  2. 1. Short Pulses in Engineered Nonlinear Media

    Author : Stefan Holmgren; Fredrik Laurell; Derryck Reid; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; KTiOPO4; frequency conversion; mode-locked lasers; ultra-fast lasers; visible lasers; short pulses; ultrafast nonlinear optics; diagnostic applications of nonlinear optics; nonlinear optical materials; Physics; Fysik;

    Abstract : Short optical pulses and engineered nonlinear media is a powerful combination. Mode locked pulses exhibit high peak powers and short pulse duration and the engineered ferro-electric KTiOPO4 facilitates several different nonlinear processes. READ MORE

  4. 2. Modelling of Moving Contact Lines in Two-Phase Flows

    Author : Hanna Holmgren; Gunilla Kreiss; Stefan Turek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational fluid dynamics; Two-phase flow; Contact lines; Scientific Computing; Beräkningsvetenskap;

    Abstract : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. READ MORE

  5. 3. Metabolic risk markers and relative survival in patients with aortic stenosis requiring surgery

    Author : Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic stenosis; aortic valve surgery; coronary artery disease; prospective cohort study; risk markers; lipoprotein a ; apolipoproteins; proteomics; troponin T; C-reactive protein; relative survival; observed survival; kardiologi; Cardiology;

    Abstract : Background: Aortic stenosis (AS) is the most common valve disorder requiring surgery in developed countries. The etiology of AS is only partly known.  Identification of new biomarkers in prospective studies could lead to novel insights in the etiology of AS, and possibly lead to improved clinical management.
