2. 1. Characterization and Linearization of Multi-channel RF Power Amplifiers

   Author : Shoaib Amin Amin; Peter Händel; Daniel Rönnow; Ulf Gustavsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The demands for high data rates and broadband wireless access require the development of wireless systems that can support wide and multi-band signals. To deploy these signals, new radio frequency (RF) front-ends are required which impose new challenges in terms of power consumption efficiency and sources of distortion e.g., nonlinearity. READ MORE

4. 2. ZnO and CuO Nanostructures: Low Temperature Growth, Characterization, their Optoelectronic and Sensing Applications

   Author : Gul Amin; Magnus Willander; Omer Nour; Anastasios Travlos; Linköpings universitet; []
   Keywords : Zinc oxide; Copper II oxide; Nanostructures; Hydrothermal growth; Light emitting diodes.;

   Abstract : One dimensional (1-D), zinc oxide (ZnO) and copper (II) oxide (CuO), nanostructures have great potential for applications in the fields of optoelectronic and sensor devices. Research on nanostructures is a fascinating field that has evolved during the last few years especially after the utilization of the hydrothermal growth method. READ MORE

5. 3. Study on the Earth’s Surface Mass Variations using Satellite Gravimetry Observations

   Author : Hadi Amin; Mohammad Bagherbandi; Lars Sjöberg; Faramarz Nilfouroushan; Martin Horwath; Högskolan i Gävle; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

   Abstract : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.

6. 4. The relationship between inflammation and structural changes in the airways of the lower and upper respiratory tract : Studies in patients with asthma, Sjögren's syndrome, rhinitis and children with otitis media with effusion

   Author : Kawa Amin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; bronchial hyperresponsiveness; inflammatory cells; asthma; rhinitis; Sjögren s syndrome; children with otitis media with effusion; immunohistochemistry; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Abstract : The pathophysiology of asthma, Sjögrens syndrome (SS), rhinitis, and otitis media with effusion (OME) in children has been extensively investigated in upper and lower respiratory tract, respectively, and shown to comprise structural changes in the airways and involvement of inflammatory cells. By comparing diseases that have bronchial hyperresponsivenses or mucosal inflammation as a common denominator, it may be possible to learn more about the mechanisms underlying inflammation in the upper and lower respiratory tract.

7. 5. Renal Klotho in mineral metabolism

   Author : Risul Amin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Calcium and phosphorous are critical elements in a number of physiological processes, including maintenance of bone structure, cell signaling and energy metabolism. Their endocrine regulation is tightly controlled through a number of feedback mechanisms involving parathyroid hormone (PTH), vitamin D and the recently discovered fibroblast growth factor 23 (FGF23).
