This paper investigates the performance of high rate IEEE 802.15.4 UWB PHY schemes. Evaluation takes place over office, residential and outdoor IEEE channel models via Monte-Carlo simulation. Special attention is given to the highest rate (27.24 Mbps) scheme that suffers from intersymbol interference (ISI) over NLOS outdoor and residential channels. Optimum bit-to-symbol mapping (OBM), ISI cancell
Introduction: This study aims to determine if evidence exists for a lasting effect of the Diabetes Prevention Program (DPP) lifestyle intervention on activity levels by comparing objectively collected activity data between the DPP Outcome Study (DPPOS) cohort and adults from the National Health and Nutrition Examination Survey (NHANES; 2003-2006). Methods: Average minutes/day of light and moderate
Atrial fibrillation (AF) is currently considered a risk factor for stroke. Depending on the severity of clinical factors (risk scores) a recommendation for full anticoagulation is made. Although AF is most certainly a risk factor for ischemic stroke, it is not necessarily the direct cause of it. The causality of association between AF and ischemic stroke is questioned by the reported lack of tempo
In the quest for detailed spectroscopic insight into the electronic structure at solid surfaces in a large momentum range, we have developed an advanced experimental approach. It combines the 3D detection scheme of a time-of-flight momentum microscope with an optimized filling pattern of the BESSY II storage ring. Here, comprehensive data sets covering the full surface Brillouin zone have been use
Objective/Background The objective was to analyze the long-term durability of intra-operatively placed Palmaz stents for type Ia endoleaks, and the evolution of aneurysm neck morphology. Methods This was a retrospective cohort study conducted at a tertiary referral centre. Patients treated between 1998 and 2012 were reviewed with regard to pre-, intra-, and post-operative data. Crude and relative
Objective: To give a narrative overview of meniscal tears with a radiologic emphasis on the morphologic type, technical considerations, and on the relevance of the type of meniscal tear in the context of osteoarthritis (OA) research. Design: Total 20 years of the PubMed database were searched for epidemiological, radiological, arthroscopic and biomechanical reports, and review articles focusing on
Background: Activation of the trigeminal-autonomic reflex, involving the trigeminal ganglion, the superior salivatory nucleus and the sphenopalatine ganglion (SPG) is crucial in the pathophysiology of cluster headache (CH). Since pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38) is present both in the SPG and the trigeminal ganglion (TG) and its role in migraine has been described,
Introduction: ECG-derived vectorcardiography (VCG) has diagnostic and prognostic value in various diseases. Hypertrophic cardiomyopathy (HCM), a genetic disease with unexplained left ventricular hypertrophy, is one of the most common causes of sudden cardiac death (SCD) in young persons. Genotype positive status is associated with increased risk of systolic dysfunction, heart failure, and (SCD). H
Background: The use of methylisothiazolinone (MI) in cosmetic products has caused an unprecedented epidemic of MI contact allergy. Current data concerning exposures at a European level are required. Objectives: To describe demographics and MI exposures for European patients with MI contact allergy. Methods: Eleven European dermatology departments from eight European countries prospectively collect
BACKGROUND: Gastrointestinal complications in diabetes may affect glucose and endocrine homeostasis. Glucosedependent insulinotropic peptide (GIP), glucagon-like peptide-1 (GLP-1), and leptin regulate glucose homeostasis, food intake, and gastric emptying. AIM: The aim was to investigate associations between diabetes complications and glucose homeostasis and plasma levels of GIP, GLP-1, and leptin
Environmental Integration in Competition and Free-Movement Laws engages in a comprehensive analysis of the obligation of Article 11 TFEU (integration of environmental protection requirements) in the three core areas of EU internal market law: competition, state aid, and free movement. It develops a theoretical framework for integrating environmental and other policies and compares how environmenta
Lymphedema is the accumulation of lymph fluid in the interstice with secondary tissue changes. The accumulated lymph stimulates adipose tissue deposition, and a marked adipose tissue hypertrophy can be seen in patients with chronic lymphedema. The basis for all lymphedema treatment is adequate compression therapy. However, if the lymphedema has started to transform into adipose tissue, conservativ
UBER is often described as disruptive innovator. This paper examines whether the UBER model disrupts the classical competition analysis thereby creating the uber-cartel, a cartel to which the normal competition rules don’t apply. This working paper on UBER and UBER-like business models examines issues that such a model faces with regard to labour and competition law with a particular focuses on th
Dercum’s disease is a rare disease characterized by chronic pain (>3 months) in the adipose tissue, generalized overweight, and a number of associated symptoms. The pain is often disabling and resistant to traditional analgesics. Liposuction of Dercum’s disease was first described in 1987, and two prospective controlled studies have demonstrated that it can give pain relief and improve quality of
The Agency Effectiveness Study explores a wide range of the daily concerns faced by competition agency heads and their staff, with an emphasis on the formal and informal ways in which they are addressed. Managing and operating a competition agency is very much a process of learning-by-doing. The aim of the study is, therefore, to capture and make available the know-how that competition agency offi
