W pracy podjęto próbę wykorzystania modelowania wielopoziomowego do określenia determinant ryzyka bezrobocia oraz skali heterogeniczności przestrzennej zjawiska. W analizie skoncentrowano się w głównej mierze na indywidualnych cechach respondentów. W związku z powyższym wykorzystano bazę danych ESS, która umożliwia budowę struktury trzypoziomowej (poziom mikro, mezo i makro) oraz zawiera szereg informacji...
A simple design of one stage, low power cryogenic amplifier at 2.2–3GHz range is presented. The design was numerically simulated by freely available microwave library SuperMix. The amplifier constructed according to the numerically optimized design was measured in cryogen-free refrigerator. The measured noise temperature T N ≈6K and gain G≈15.5dB are in good agreement with numerical simulations.
Interest in the application of advanced proteomics technologies to human blood plasma- or serum-based clinical samples for the purpose of discovering disease biomarkers continues to grow; however, the enormous dynamic range of protein concentrations in these types of samples (often >10 orders of magnitude) represents a significant analytical challenge, particularly for detecting low-abundance candidate...
