  2. 1. Multiport Antenna Systems for Space-Time Wireless Communications

    Author : Nima Jamaly; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spatial Correlation; Multiport Matching Efficiency; Multiport Antennas; Uncorrelated Multipath.; Richness Threshold; Multiport Effective Length; Pattern Overlap Matrix; Multiport Effective Area; Non-rich Multipath; Covariance Matrix; Predictor Antenna System; Correlated Multipath;

    Abstract : Multiport antenna systems are indispensable part of modern wireless communication systems. Their crucial impact on the overall performance requires sufficient regard and dedication to a precise design and characterisation. This concern has been to a considerable extent addressed in the frame of the current thesis. READ MORE

  4. 2. Chronic kidney disease : a clinical model of premature vascular aging

    Author : Lu Dai; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Patients with chronic kidney disease (CKD) are prone to develop an accelerated vascular aging phenotype characterized by vascular calcification (VC), a major culprit of cardiovascular complications and premature death. While VC has been recognized as an active pathophysiologic process with involvement of specific mediators and effectors, the coexistence of traditional risk factors (i. READ MORE

  5. 3. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

    Author : Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE
