Multi-link MIMO channel modeling using geometry-based approach

Geometry-based stochastic channel models (GSCMs) are extended to support multi-link simulations by applying the concept of common clusters. This novel approach aims to control the correlation between different links, inter-link correlation, by adjusting the amount of power simultaneously propagating via the same clusters in the different links. The behavior of common clusters is analyzed based on

Whole-exome sequencing of pediatric acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL), the most common malignant disorder in childhood, is typically associated with numerical chromosomal aberrations, fusion genes or small focal deletions, thought to represent important pathogenetic events in the development of the leukemia. Mutations, such as single nucleotide changes, have also been reported in childhood ALL, but these have only been studied by s

On the Relation between Air void system parameters and Salt frost scaling

An attempt to develop a tool based on analysis of the air void system in concrete for an early assessment of salt frost scaling resistance of concrete is presented. Relations between the air void system parameters and scaling are discussed. A new technique based on the accumulated surface area of all air voids is presented. This is a short description of the project. The full report is available

Longitudinal relationships between fluid status, inflammation, urine volume and plasma metabolites of icodextrin in patients randomized to glucose or icodextrin for the long exchange

Background. Randomized trials have shown that icodextrin reduces the volume of extra-cellular fluid (ECFv) with variable effects on residual renal function. To explore this fluid shift and its possible mechanisms in more detail, prospectively collected data from one such trial, including measures of inflammation (C-reactive protein, tumor necrosis factor-a, albumin and low and high molecular weigh

Risk Factors for Medically Treated Hypocalcemia after Surgery for Graves' Disease: A Swedish Multicenter Study of 1,157 Patients.

BACKGROUND: For reasons that remain unclear, surgery for Graves' disease is associated with a higher risk of hypocalcemia than surgery for benign atoxic goiter. In the present study, we evaluated risk factors for postoperative hypocalcemia in patients undergoing operation for Graves' disease. METHODS: Data from 1,157 patients who underwent operation for Graves' disease between 2004 and 2008 were

Inventory Control when the Lead-time Changes

A single-echelon inventory system with continuous review and Poisson demand is considered. There are standard linear holding and backorder costs but no ordering or set-up costs. We study a change in the lead-time, which is rather typical in connection with application of a Just-In-Time philosophy. Our main focus is a lead-time decrease but we also consider a lead-time increase. Due to the lead-tim

Cerebrospinal fluid levels of IL-6 are decreased and correlate with cognitive status in DLB patients.

Inflammatory processes have previously been shown to influence cognition and progression of dementia. An involvement of interleukin (IL)-6 has in particular been suggested as altered levels of IL-6 in cerebrospinal fluid (CSF) have been found in patients with Alzheimer's disease (AD). Also, an association between cognitive decline and levels of IL-6 in CSF have been reported. The aim of the presen

EPR systems and new business models. Reuse and recycling of textiles in the Nordic region

This report is the outcome of Part I of a research project entitled An EPR system and new business models to in- crease reuse and recycling of textiles in the Nordic region. The overall aim of the project is to propose policy packages in Nordic countries which would support extended producer responsibility (EPR) systems and innovative business models which promote greater reuse and recycling of us

Sentinel Node Location in Trunk and Extremity Melanomas: Uncommon or Multiple Lymph Drainage Does Not Affect Survival

Patients with cutaneous melanoma (CM) on the trunk have a worse prognosis than those with extremity CM. One reason could be multiple or uncommon (outside axilla or groin) sentinel node locations (SNLs). We identified 859 patients who underwent sentinel node biopsy for trunk (n = 465) or extremity (n = 394) CM in three Swedish healthcare regions from 2000 to 2008. We collected patient, tumor, and s

Storkonflikten 1980 och andra stora arbetskonflikter i Sverige

In the article, the Great Conflict of 1980 is compared with the general strike and great lockout of 1909 and the 1945 metalworkers’ strike. Depending on how they are measured, each of them could lay claim to be the largest labour conflict in Swedish history. While the strikes of 1909 and 1945 ended up in union defeats, the outcome of the 1980 conflict was a severe setback for SAF. The 1909 LO stri

Zinc supplementation inhibits complement activation in age-related macular degeneration.

Age-related macular degeneration (AMD) is the leading cause of blindness in the Western world. AMD is a multifactorial disorder but complement-mediated inflammation at the level of the retina plays a pivotal role. Oral zinc supplementation can reduce the progression of AMD but the precise mechanism of this protective effect is as yet unclear. We investigated whether zinc supplementation directly a

Toward a relevant agenda for warehousing research: literature review and practitioners’ input

The main purpose of this research is to provide an agenda for future warehousing research relevant for both academic development and practitioners’ needs. In order to suggest a practically relevant future research agenda, first a comprehensive literature review was performed to identify research areas covered in the literature. Then, 15 warehouse managers and senior consultants were interviewed to
