Economic theory commonly distinguishes between different time horizons such as the short run and the long run, each with its own relationships and its own dynamics. Engle (1974) proposed a bandspectrum regression to estimate such models. This paper proposes a new estimator for non-stationary panel data models, a bandspectrum cointegration estimator. The bandspectrum cointegration estimator uses fi
A class-C CMOS harmonic VCO maximizes the oscillation amplitude by operating the active devices operating in class C, while the bias-current noise is naturally rejected by the topology. Drawing 1.4mA from a 1V supply, the 0.13µm CMOS prototype exhibits an average phase noise of -130dBc/Hz at 3MHz offset over the 4.90-to-5.65GHz tuning range, for an FoM of 194.5dBc/Hz.
The paper gives a review of pole-placement design for systems with known parameters, then focuses entirely on the servos. Adaptive pole-placement algorithms are discussed, leading to the formulation of explicit and implicit schemes, and simulation of the behaviour of the alorithms is given.
Massive multiple-input multiple-output (MIMO) is one of the main candidates to be included in the fifth generation (5G) cellular systems. For further system development it is desirable to have real-time testbeds showing possibilities and limitations of the technology. In this paper we describe the Lund University Massive MIMO testbed – LuMaMi. It is a flexible testbed where the base station operat
The article surveys the Medieval and Early Modern reception of two ancient Greek myths: the stories about the Phoenician princess Europe and her brother Kadmos. During the 12th - 17th century the interpretation of pagan myths flourished in Europe, justified by allegorical exegesis. The myths of Europe and Kadmos were viewed as disguised teachings containing historical, moral or religious truth. Fo
B cell lymphomas (BCLs) are a group of severe cancers, afflicting both men and women at different ages. Gene expression profiling (GEP), have during the latest decades fundamentally contributed to a better classification and biological understanding of the different BCLs. Most studies using GEP have analyzed mRNA from tumor tissue constituted of both tumor cells and non-malignant bystander cells.
