  1. 1. Attosecond photoelectron interferometry: from wavepackets to density matrices

    Författare :Hugo Laurell; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum state tomography; Decoherence; Photoionization; Fysicumarkivet A:2023:Laurell;

    Sammanfattning : Through the advent of high-order harmonic generation and attosecond light pulses, photoionization dynamics has been studied on the attosecond time-scale, the intrinsic time-scale of such dynamics. When the electron leaves the atomic potential a phase shift is imprinted on the electron wavefunction. LÄS MER

  3. 2. The role of industry context for new venture internationalization : Evidence from the medical technology sector

    Författare :Hélène Laurell; Svante Andersson; Per Servais; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The medical technology sector consists of numerous small niche markets. Approximately 95% are small and medium sized enterprises, many of which are start-ups that develop technological breakthroughs for the healthcare sector. The competition in this sector is highly global. LÄS MER

  4. 3. Genetic studies of congenital upper limb anomalies

    Författare :Tobias Laurell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall aim of the work reported in this thesis is to improve epidemiological and genetic knowledge of congenital upper limb anomalies (CULA). To accomplish the specific aims of each paper several different methods and approaches have been used such as register studies, array comparative genome hybridization, Sanger sequencing, exome sequencing and functional studies using Lacz enhancer assay, Zebrafish morpholinos and computational transcription factor binding site prediction.

  7. 5. Hormone-sensitive lipase: Molecular analyses of the human gene; structural and evolutionary aspects on expression, alternative splicing and cold adaptation

    Författare :Henrik Laurell; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymologi; Proteiner; Proteins; enzymology;

    Sammanfattning : Hormone-sensitive lipase (HSL) is a key enzyme in adipose tissue that hydrolyses stored fat (triacylglycerol). The activity of HSL is under strict hormonal and neural control. LÄS MER
