1. New Approaches to Large-Scale Electronic Structure Calculations
Sammanfattning : Recent years have witnessed a growing interest of the scientific community for the use of ab initio and density functional theory methods in theoretical studies of molecules containing many atoms. However, the `scaling wall' of some of the most accurate of such methods is often an obstacle for their applicability to systems of real-life interest, e. LÄS MER
2. Baseband Processing for 5G and Beyond: Algorithms, VLSI Architectures, and Co-design
Sammanfattning : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.

3. Extending the Reach of Accurate Wavefunction Methods
Sammanfattning : Multiconfigurational quantum chemistry methods, and especially the multiconfigurational self-consistent field (MCSCF) and multireference perturbation theory (MRPT2), are powerful tools, particularly suited to the accurate modeling of photochemical processes and transition metal catalysis. However, they are limited by their high computational cost compared to other methods, especially density functional theory. LÄS MER
4. Genetic epidemiological approaches to the study of risk factors for cardiovascular diseases
Sammanfattning : Cardiovascular disease (CVD) is one of the most common causes of death in most developed countries. Genetic and environmental factors influence CVD and its risk factors in a complex fashion. Parallel to this, new statistical methods are being developed to make use of the new molecular genetic information. LÄS MER
5. Longitudinal study of the impact on hearing from aging, genetic background and environmental exposures in male twins
Sammanfattning : Background: Hearing loss is a process that normally develops over many years, and the ability to hear high–frequency sounds is often reduced first. Age, repeated exposure to loud noise and other risk factors, diseases, medications and injury, can damage the various structures of the ear and interfere with hearing. LÄS MER
