  1. 11. Apoptosis and inflammation regulation after injury to the developing brain

    Författare :Wei Han; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The brain shows greater plasticity in early life than in maturity, which paradoxically renders the organ more vulnerable to hypoxia-ischemia (HI)- and cranial irradiation (IR)- induced damage. Apoptosis after a HI insult is more pronounced in the immature vs. LÄS MER

  3. 12. Biosensing platforms using graphene based bioreactive nanostructures with various dimensions

    Författare :Yuanyuan Han; Klaus Leifer; Jöns Hilborn; Hu Li; Boukherroub Rabah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; nanoparticles; nanostructure; biosensors;

    Sammanfattning : Nanomaterials have brought new aspects and improvements to the biosensing field due to their unique physical and chemical properties that are not shown in the bulk state. This thesis focuses on concepting, developing and testing of biosensors where nanomaterials including graphene gold nanoparticles (AuNPs) and magnetic nanoparticles (MNPs) constitute the biosensors.

  4. 13. Effects of eye and neck muscle proprioception on ocular motor control in normal and strabismic subjects

    Författare :Ying Han; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :strabismus; binocular function; proprioception; eye position; muscle vibration; eye muscle; neck muscle; hand pointing; accommodative vergence movement; dynamics;

    Sammanfattning : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.

  5. 14. Robust and Efficient Federated Learning for IoT Security

    Författare :Han Wang; Shahid Raza; György Dán; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet of Things; Federated Learning; Machine Learning; Intrusion Detection System; Communication Efficiency; Robustness; Adversarial AI; Device Fingerprinting; Device Identification; Cyber Threat Intelligence; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : The widespread adoption of Internet of Things (IoT) devices has led to substantial progress across various industrial sectors, including healthcare, transportation, and manufacturing. However, these devices also introduce significant security vulnerabilities because they are often deployed without adequate security measures, making them susceptible to cyber threats. LÄS MER

  7. 15. Structural Decorations in Viruses : Unraveling Acquired Functional Structures in Icosahedral RNA Virus Capsids

    Författare :Han Wang; Kenta Okamoto; Sarah Butcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Viruses; RNA viruses; capsid; structure; cryo-EM; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : Viruses have a profound impact worldwide, posing challenges to animal welfare, agriculture, human health, and the ecosystem. This thesis examines the realm of non-enveloped icosahedral double-stranded (ds)RNA and single-stranded (ss)RNA viruses through three studies. LÄS MER
