21. Stochastic Resonance and Noise-Assisted Signal Transfer : On Coupling Effects of Stochastic Resonators and Spectral Optimization of Fluctuations in Random Network Switches
Sammanfattning : Recent research shows that noise or random fluctuations must not always be destructive in Nature by degrading system performance. On the contrary, in nonlinear systems they can synchronize systems or enhance the quality of signal transmission. The latter possibility is reported in the thesis. LÄS MER
22. Time-resolved detection of temporally correlated, single-charge tunnelling
Sammanfattning : We report real-time detection of the single charges that constitute a small electrical current, as they flow through a nano-electronic device. This represents a direct demonstration of charge discreteness in an electrical current. LÄS MER
23. Ionic and electronic transport in electrochemical and polymer based systems
Sammanfattning : Electrochemical systems, which rely on coupled phenomena of the chemical change and electricity, have been utilized for development an interface between biological systems and conventional electronics. The development and detailed understanding of the operation mechanism of such interfaces have a great importance to many fields within life science and conventional electronics. LÄS MER
24. Two novel combination therapies of glioblastoma multiforme from a Cx43 perspective : studies of in vitro models
Sammanfattning : The group of patients suffering from the malignant brain tumour glioblastoma multiforme (GBM) have a median survival of only about one year. Thus, new treatment strategies are urgently needed. Gap junctions are intercellular channels, permitting intercellular transfer of water soluble substances. LÄS MER
25. Development of Cryogenic Low Noise 4-8 GHz HEMT Amplifier and its Advanced Characterization
Sammanfattning : In most radio astronomy instrumentation, cryogenic low noise amplifiers (LNA) are used as intermediate frequency (IF) amplifiers. The system noise temperature is among the most important parameters of a receiver and requires state of the art components. LÄS MER
