1. 1. Proximity Ligation : Transforming protein analysis into nucleic acid detection through proximity-dependent ligation of DNA sequence tagged protein-binders

   Författare :Simon Fredriksson; Larry Gold; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; Proximity ligation; proteomics; SELEX; antibody; DNA microarray; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Molecular Medicine; molekylär medicin genetik och patologi ;

   Sammanfattning : A novel technology for protein detection, proximity ligation, has been developed along with improved methods for in situ synthesis of DNA microarrays. Proximity ligation enables a specific and quantitative transformation of proteins present in a sample into nucleic acid sequences. LÄS MER

3. 2. Charge Transport in Semiconductor Nanowire Quantum Devices: From Single Quantum Dots to Topological Superconductors

   Författare :Mingtang Deng; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple Andreev reflection; SQUID; Proximity effect; the Josephson effect; Cooper pair; the Kondo effect; the Zeeman effect; Quantum dot; InSb; Nanowires; Transport; Fysicumarkivet A:2013:Deng; Majorana bound state; Yu-Shiba-Rusinov state; Andreev bound state;

   Sammanfattning : This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured.

4. 3. Modelling of Terahertz Planar Schottky Diodes

   Författare :Aik-Yean Tang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S-parameter extraction; Electro-thermal; Schottky diodes; Skin effect; Electromagnetic; Frequency multipliers; High-power frequency multiplier; Current crowding; Proximity effect; Submillimetre wave generation and detection; Geometric modelling; Gallium Arsenide;

   Sammanfattning : This thesis deals with the modelling of THz planar Schottky diodes, focusing on analyses of the geometry- dependent parasitics and the diode chip thermal management. Moving towards higher operating frequencies, the electromagnetic couplings pose significant limitations on the diode performance. LÄS MER

5. 4. Labour mobility and plant performance : The influence of proximity, relatedness and agglomeration

   Författare :Rikard Eriksson; Urban Lindgren; Gunnar Malmberg; Andrés Rodríguez-Pose; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agglomeration economies; labour mobility; plant performance; geographical proximity; related variety; clusters; Human geography; economic geography; Kulturgeografi; ekonomisk geografi; Economic geography; Ekonomisk geografi; Social and Economic Geography; kulturgeografi;

   Sammanfattning : The purpose of this thesis is to shed new light on the theorizations discussing the economic benefits of geographical clustering in a space economy increasingly characterized by globalization processes. This is made possible through the employment of a plant-perspective and a focus on how the relative fixity and mobility of labour influence plant performance throughout the entire Swedish economy.

7. 5. Diffractive Optics Design

   Författare :Jörgen Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer-generated waveguide hologram; diffractive optics; fan-out; millimeter wave radiation; proximity effect; optimal-rotation-angle method; kinoform; integrated optics; beam shaping; outcoupling grating; scalar optics;

   Sammanfattning : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). LÄS MER
