This paper presents a comparison of the image rejection between Gilbert mixer and the passive mixer. A simple model for mixers is set up, and the image rejection performance of passive and Gilbert mixer is analyzed based on it. Simulations and calculations were done to compare the image rejection of the two mixers. The results show that the Gilbert mixer, comparing with the passive one, shows a st
This article focuses on processes of social change in Sweden, an advanced welfare state. it starts by pointing out the failure of contemporary welfare state theory to deal with the imbalance between the goal of equlality and the goal of efficiency in the production and distribution of both capital and social values.

The international community has thus acknowledged that the issue requires a collective response. Climate change has also been considered a common concern of humankind. The concept of common co
We are developing a prototype system for simultaneous digital breast tomosynthesis (DBT) and mechanical imaging (MI). MI maps the local pressure distribution during clinical exams, to distinguish breast abnormalities from the normal tissue. Both DBT alone, and MI when combined with digital mammography, have demonstrated the ability to reduce false positives; however, the benefit of combining DBT w
