1. 6. Gene-Environment Interaction in Adolescent Deviant Behaviour

   Författare :Kent W. Nilsson; Leif Lindström; Lars Oreland; Jerzy Leppert; John Öhrvik; Rickard L. Sjöberg; Marie Åsberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Adolescent; Alcohol; Criminology; Genes; Environment; Monoamine Oxidase; Serotonin; Social Support; Neurobiologi; Neurobiology; Neurobiologi;

   Sammanfattning : The overall aim of this thesis was to explore gene-environmental (G*E) interactions in relation to deviant behaviour among 200 Swedish adolescents, with a focus on criminality, alcohol consumption and depressive symptoms. Those behaviours have been extensively investigated in relation to both psychosocial and biological risk factors. LÄS MER

3. 7. Selected Topics on Reconfigurable Intelligent Surfaces

   Författare :Emad Farouk Ibrahim; Rickard Nilsson; Jaap van de Beek; Laura Cottatellucci; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Sammanfattning : Reconfigurable intelligent surface (RIS) is a promising technology for wireless communications applications. A RIS is a thin planar array that consists of multiple reflecting elements, each of which is connected to a tunable chip and can induce a controllable reflection coefficient to the incident signal.

4. 8. RNA-based spatial characterization of cell and tissue heterogeneity

   Författare :Elin Lundin; Mats Nilsson; Rickard Sandberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Padlock probes; in situ sequencing; single cell resolution; single nucleotide variant resolution; spatial transcription profiling; Biochemistry; biokemi;

   Sammanfattning : Technical advances in cell biology have revolutionized the field of cell biology. With new technology it is now possible to address scientific questions in cell biology at the molecular level. LÄS MER

5. 9. Design, Analysis and Prototyping of Spectrally Precoded OFDM

   Författare :Medhat Mohamad; Jaap van de Beek; Rickard Nilsson; Majid Nasiri Khormuji; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Sammanfattning : Despite shifting towards mm-wave bands, the sub 6-GHz band will continue tobe a fundamental spectral band in 5G. Yet, the severe crowdedness of this bandmakes a well constrained spectrum one of the critical 5G requirements. LÄS MER

7. 10. Spectrally Precoded OFDM-Design and Analysis

   Författare :Medhat Mohamad; Jaap van de Beek; Rickard Nilsson; Mérouane Debbah; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OFDM; spectral precoding; out of band emission; 5G; Signalbehandling; Signal Processing;

   Sammanfattning : Despite shifting towards mm-wave bands, the sub-6 GHz band will continue to be a fundamental spectral band in 5G. However, the severe congestion in this band makes a well-constrained spectrum a critical requirementof 5G. LÄS MER
