26. Decryption Failure Attacks on Post-Quantum Cryptography
Sammanfattning : This dissertation discusses mainly new cryptanalytical results related to issues of securely implementing the next generation of asymmetric cryptography, or Public-Key Cryptography (PKC).PKC, as it has been deployed until today, depends heavily on the integer factorization and the discrete logarithm problems.

27. Comorbidity and vascular risk factors associated with idiopathic normal pressure hydrocephalus : the INPH-CRasH Study
Sammanfattning : Idiopathic normal pressure hydrocephalus (INPH) is a dementia treatable by insertion of a cerebrospinal fluid shunt. It has been suggested that INPH has similar pathophysiological mechanisms as cerebrovascular disease, but the vascular risk factor (VRF) profile of INPH patients has not been assessed using a modern epidemiological approach.

28. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications
Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER
29. Hypothalamic and cortical control of jaw reflexes
Sammanfattning : The subject of the thesis is a study of the projections from low threshold oral and face afferents to the cerebral cortex and of descending motor control mechanisms originating in the cerebral cortex or the hypothalamus and influencing the jaw reflexes.Cats anaesthetized with chi oral ose were used for the experiments.

30. Recurrent events and secondary prevention after acute cerebrovascular disease
Sammanfattning : Background Patients who experience a stroke or transient ischemic attack (TIA) are at high risk of recurrent stroke, but little is known about temporal trends in unselected populations. Reports of low adherence to recommended treatments indicate a need for enhanced secondary preventive follow-up to achieve the full potential of evidence-based treatments. LÄS MER
