A flexible 100-antenna testbed for Massive MIMO
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
A methodology for 7D warping and deformation monitoring using time-lapse seismic data
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
A monotonicity estimate of the biharmonic Green function, Arch. Math. (Basel) 82 (2004) 240-244.
Asymptotic performance of woven graph codes
Constructions of woven graph codes based on constituent block and convolutional codes are studied. It is shown that within the random ensemble of such codes based on s-partite, s-uniform hypergraphs, where s depends only on the code rate, there exist codes satisying the Varshamov-Gilbert (VG) and the Costello lower bound on the minimum distance and the free distance, respectively.
High-temperature oxidation behaviour of nanostructure surface layered austenitic stainless steel
The present study investigates the high-temperature oxidation behaviour of nanostructure surface layered AISI 304L stainless steel. A severely deformed layer of ∼300 μm thickness, consisting of nanoscale grains (∼40 nm size) in the topmost region, is successfully developed using the surface mechanical attrition treatment (SMAT) process. The SMATed layer is substantially stable up to 700 °C; howeve
Green gentrification in European and North American cities
Although urban greening is universally recognized as an essential part of sustainable and climate-responsive cities, a growing literature on green gentrification argues that new green infrastructure, and greenspace in particular, can contribute to gentrification, thus creating social and racial inequalities in access to the benefits of greenspace and further environmental and climate injustice. In
Genome-wide analyses reveal a potential role for the MAPT, MOBP, and APOE loci in sporadic frontotemporal dementia
Frontotemporal dementia (FTD) is the second most common cause of early-onset dementia after Alzheimer disease (AD). Efforts in the field mainly focus on familial forms of disease (fFTDs), while studies of the genetic etiology of sporadic FTD (sFTD) have been less common. In the current work, we analyzed 4,685 sFTD cases and 15,308 controls looking for common genetic determinants for sFTD. We found
Model of Health-Related Quality of Life in Breast Cancer Patients Using Cross-Sectional Data: The Role of Resilience
Purpose: Resilience has been suggested as an important predictor of both physical and mental health-related quality of life in breastcancer patients. However, it is unclear why resilient women handle their diagnosis better, not only mentally, but also physically. Theaim of this study was to investigate paths between resilience, physical activity, and mental, physical, and global health-related qua
Population regulation by habitat heterogeneity or individual adjustment?
1. The habitat heterogeneity (HHH) and individual adjustment (IAH) hypotheses are commonly proposed to explain a decrease in reproduction rate with increasing population density. Higher numbers of low-quality territories with low reproductive success as density increases lead to a decrease in reproduction under the HHH, while more competition at high density decreases reproduction across all terri
The Swedish Early Psoriatic Arthritis Register -- 2-year Followup: A Comparison with Early Rheumatoid Arthritis.
OBJECTIVE :Patients with symptoms and signs compatible with psoriatic arthritis (PsA), with or without psoriasis, have been documented in the Swedish Early Psoriatic Arthritis (SwePsA) register. Our aim was to find markers for disease progression and to evaluate treatments for PsA using these data. METHODS: Patients referred to rheumatology outpatient clinics within 2 years of onset were assessed
Impact of uterine closure on residual myometrial thickness after cesarean: a randomized controlled trial.
Incomplete healing of uterine scar after cesarean has been associated with adverse gynecological and obstetrical outcomes. Several studies reported that uterine closure at cesarean influence the healing of uterine scar and the risk of uterine rupture at subsequent pregnancies: the commonly used locked single-layer suture including the decidua being associated with a four-fold increase risk of uter
Vasculitis in rheumatoid arthritis.
PURPOSE OF REVIEW: To examine the occurrence and pathophysiology of vasculitis in rheumatoid arthritis (RA), describe the epidemiology and clinical features, and provide a therapeutic perspective. RECENT FINDINGS: With improved control of RA over the past two decades, the risk of severe outcomes such as vasculitis may be decreasing. Rheumatoid vasculitis continues to be associated with longstandin
A shift register construction of unconditionally secure authentication codes
We consider the authentication problem, using the model described by Simmons. Several codes have been constructed using combinatorial designs and finite geometries. We introduce a new way of constructing authentication codes using LFSR-sequences. A central part of the construction is an encoding matrix derived from these LFSR-sequences. Necessary criteria for this matrix in order to give authentic
Postoperative Increase in B-Type Natriuretic Peptide Levels Predicts Adverse Outcome After Cardiac Surgery.
OBJECTIVE:: To evaluate the prognostic implication of changes in postoperative B-type natriuretic peptide (BNP) concentrations in patients undergoing cardiopulmonary bypass for cardiac surgery. DESIGN:: A retrospective analysis of prospectively collected clinical data. SETTING:: Cardiothoracic surgery and an intensive care unit (ICU) in a university hospital. PARTICIPANTS:: The present study inclu
Integrated Scheduling and Synthesis of Control Applications on Distributed Embedded Systems
Many embedded control systems comprise several control loops that are closed over a network of computation nodes. In such systems, complex timing behavior and communication lead to delay and jitter, which both degrade the performance of each control loop and must be considered during the controller synthesis. Also, the control performance should be taken into account during system scheduling. The
