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.

A methodology is presented for vector analysis of the image displacements (warping) between successive 3D seismic image volumes that provides 7D analysis (including lateral and vertical displacements) of in situ subsurface deformation around hydrocarbon reservoirs. The key challenges are (1) assessment of just vertical shifts is insufficient, and vector displacements should be determined; (2) robu

Popular Abstract in Swedish Nobelpriset i fysiologi och medicin 1998 gick till tre forskare från USA som gjort forskningsinsatser för upptäckten av kväveoxid (NO) vilket är en viktig signalsubstans i våra kroppar. Upptäckten av att en så liten molekyl som NO har så många funktioner i kroppen anses som en av de mest överraskande i medicinhistorien. Redan 1876 började man använda nitroglycerin som eNitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. NOS activity in vagina and cervix were much higher (3-6-fold) than in the uterus. Est

In the near future several astronomical observatories in Chile areplanning to use sodium laser guide stars to increase the sky coverageprovided by their adaptive optics facilities. Knowledge of themesospheric sodium layer behavior is crucial to predict the performanceof future laser guide star adaptive optics systems. Whereas the sodiumlayer has been observed quite extensively at several locations
