User Localization using Random Access Channel Signals in LTE Networks with Massive MIMO
Recent studies show that real-time precise user localization enables to deliver accurate beamforming in MIMO systems without the need for channel estimation. This paper presents new solutions for accurate user localization in massive MIMO LTE systems. A key novelty of the developed schemes is the ability to locate users during LTE's random access channel synchronization procedure before they are c

Genomic signatures of experimental adaptive radiation in Drosophila
Abstract Abiotic environmental factors play a fundamental role in determining the distribution, abundance, and adaptive diversification of species. Empowered by new technologies enabling rapid and increasingly accurate examination of genomic variation in populations, researchers may gain new insights into the genomic background of adaptive radiation and stress resistance. We investigated genomic v
Evidence for Faster X Chromosome Evolution in Spiders
In species with chromosomal sex determination, X chromosomes are predicted to evolve faster than autosomes becauseof positive selection on recessive alleles or weak purifying selection. We investigated X chromosome evolution inStegodyphus spiders that differ in mating system, sex ratio, and population dynamics. We assigned scaffolds to Xchromosomes and autosomes using a novel method based on flow In species with chromosomal sex determination, X chromosomes are predicted to evolve faster than autosomes because of positive selection on recessive alleles or weak purifying selection.

Full Downlink Channel Reconstruction using Incomplete Uplink Channel Measurements in Massive MIMO networks
While more and more antennas are integrated into a single mobile user equipment to increase communication quality and throughput, the number of antennas used for transmission is commonly restricted due to the concerns on hardware complexity and energy consumption, making it impossible to achieve the maximum channel capacity. This paper investigates the problem of reconstructing the full downlink c
Wireless Channel Modeling and Reconstruction in Massive MIMO Systems
The past few years have witnessed dramatic growth in the number of wirelessly connected devices, which will continue to increase in the future. Following this trend, the capacity of the wireless networks has been enhanced to provide high-quality service to tens of billions of devices. At the same time, in response to the network enhancement, each device unashamedly requests more and more throughpu

Properties of the CsI(Tl) detector elements of the CALIFA detector
In the RB experiment at FAIR, charged particles with energies up to 600 MeV and forward boosted -rays with energies up to 20 MeV need to be detected in scattering experiments. Calorimeters for nuclear physics experiments of this kind, using relativistic radioactive ion beams, require high energy resolution and high efficiency for simultaneous detection of strongly Doppler shifted -rays and high-en

Genetic correlations and their dependence on environmental similarity : insights from livestock data
Genetic correlations for a trait across environments are predicted to decrease as environments diverge. However, estimates ofgenetic correlations from natural populations are typically defined across a limited environmental range and prone to very largestandard errors, making it difficult to test this prediction. We address the importance of environmental distance on genetic cor-relations by employiGenetic correlations for a trait across environments are predicted to decrease as environments diverge.

Future development plans for the MAX IV light source: Pushing further towards higher brightness and coherence
The commissioning of the MAX IV synchrotron radiation facility in Lund marks the dawn of a new generation of storage-ring-based light sources. This new generation delivers one order of magnitude higher performance and allows realization of groundbreaking experiments on a variety of systems and materials at the atomic and molecular levels. This paper reviews the conceptual basis of the MAX IV desig

Fake drugs that could kill are on the rise in Western countries – here’s why
Fake medicines – illegal and substandard pharmaceuticals – have until now largely been a problem in low and middle-income countries. Ranging from lifestyle products to lifesaving medicines, such products are now also on the rise in the Western world. The spread is concerning, as fake medicines can be completely ineffective or extremely toxic.
Rare orbital manifestations and vasculitis, giant cell arteritis or side effects of zoledronic acid infusion?
Giant cell arteritis (GCA), affects an age group where osteoporosis is common. A well-established treatment for osteoporosis is medication with bisphosphonates. Bisphosphonates are overall well-tolerated but can trigger several different acute inflammatory reactions with systemic features and symptoms and signs from the ocular and musculoskeletal system, all of which resemble those of GCA. Here is
The European Union and the Brexit Dilemma : A very British Problem?
This paper discusses the key legal issues arising from the constitutional conceptions of both the EU and the UK in the latter’s withdrawal process. It argues that the adherent Brexit dilemma is mainly the result of the UK’s non-codified constitution on the one hand, exposing legal uncertainty over institutional procedures, regional involvement, or the precise status of international law.
