  1. 1. Information-theoretic Privacy and Secrecy in Biometric Identification and Authentication

    Författare :Linghui Zhou; Tobias J. Oechtering; Mikael Skoglund; Hideki Yagi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information theory; identification; authentication; privacy; secrecy; Informationsteori; identifiering; autentisering; integritet; sekretess; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Nowadays, biometrics are more and more deployed to reinforce traditional authentication or identification that uses keys, passwords, etc. Biometric identification and authentication have been studied from various information-theoretic perspectives, where privacy and secrecy are two important aspects.

  3. 2. Gymnasieelevers kommunikativa strategier i matematikklassrummet : En fallstudie av ett smågruppsarbete om derivata

    Författare :Marie Bergholm; Christer Bergsten; Iiris Attorps; Ewa Bergqvist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical discourse; commognition; participation; matematizing; subjectifying; identifying; small group learning; Matematisk diskurs; kommognition; deltagande; matematisera; identifiering; subjektifiering; lärande i smågrupper;

    Sammanfattning : Denna fallstudie belyser gymnasieelevers arbete i små grupper med ett problem kopplat till derivata och syftar till att belysa faktorer som gynnar eller hindrar individernas deltagande i och utveckling av den matematiska kommunikationen i klassrummet. Studien har sin teoretiska förankring i Anna Sfards kommognitiva ramverk, där lärande i matematik ses som deltagande i en matematisk diskurs. LÄS MER

  4. 3. Structural investigation of SOD1 aggregates in ALS : identification of prion strains using anti-peptide antibodies

    Författare :Johan Bergh; Thomas Brännström; Stefan L. Marklund; Peter M. Andersen; Joakim Bergström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; prion; motor neuron disease; neurodegeneration; strain; seeding; protein aggregation; transgenic mice; peptide antibodies; Neurology; neurologi;

    Sammanfattning : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. LÄS MER

  5. 4. Satellite cells in human skeletal muscle : molecular identification quantification and function

    Författare :Mona Lindström; Lars-Eric Thornell; Hannu Kalimo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; satellite cell markers; NCAM; Pax7; MyoD; myogenin; DLK1 FA1; c-Met; human skeletal muscle; immunohistochemistry; muscle growth; muscle hypertrophy; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; anatomi; Human Anatomy;

    Sammanfattning : Skeletal muscle satellite cells located between the plasma membrane and the basal lamina of muscle fibres, could for many years, only be studied in situ by electron microscopy. The introduction of immunohistochemistry and the discovery of molecular markers of satellite cells then made them accessible for light microscopic studies and a wealth of information is today available.

  7. 5. Identification of young people at risk of sexual ill health : implementing a new tool in youth clinics

    Författare :Sofia Hammarström; Per Nilsen; Susanne Bernhardsson; Malin Lindroth; Gisela Priebe; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescents; Chlamydia; Implementation; Risk assessment; Sexually transmitted infections; Sexual violence; Unplanned pregnancy; Youth clinic.;

    Sammanfattning : Background: Young people are at increased risk of sexual ill health in terms of sexually transmitted infections, unintended pregnancy, and sexual violence. There is limited knowledge of evidence-based preventive practices for identification of young people at risk of sexual ill health when in contact with health care. LÄS MER
