Collection of microlevel Safety and efficiency Indicators with Automated Video Analysis

This paper revises the theoretical grounds for relation of the micro-level behaviour indicators to the safety and efficiency (level-of service) of the local traffic system. Automated video analysis is suggested as a tool for collection of the individual data about road users driving trajectories and speeds and interaction with other road users. The authors describe the current state of the video a

Fundamental bounds on extraordinary transmission with experimental validation

This paper presents a study of extraordinary transmission (EoT) through arrays of sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating the transmission coefficient over a bandwidth to the static polarizability. The sum rule is rigorously derived for arbitrary periodic apertures in thin screens. By this sum rule we establish a physical bound o

Iceland should replace its central bank with a currency board

Since its independence in 1918, Iceland has tried a number of monetary regimes. They have all failed to provide monetary stability. Iceland is too small to conduct an independent monetary policy. What should Iceland do? We arrive at the conclusion that a currency board with the euro as the reserve currency is the best choice. A currency board delivers monetary stability through exchange rate stabiSince its independence in 1918, Iceland has tried a number of monetary regimes.

Lung bioengineering : advances and challenges in lung decellularization and recellularization

PURPOSE OF REVIEW: Bioengineering the lung based on its natural extracellular matrix (ECM) offers novel opportunities to overcome the shortage of donors, to reduce chronic allograft rejections, and to improve the median survival rate of transplanted patients. During the last decade, lung tissue engineering has advanced rapidly to combine scaffolds, cells, and biologically active molecules into fun

Characteristics of healthy vascular ageing in pooled population-based cohort studies : the global Metabolic syndrome and Artery REsearch Consortium

OBJECTIVE: Arterial ageing is characterized by increasing arterial stiffness as measured by pulse wave velocity (PWV). This process is enhanced in participants with early vascular ageing (EVA), but slowed in participants with healthy vascular ageing (HVA). We aimed to describe characteristics of EVA and HVA in a transcontinental study including 11 cohorts.METHODS: In all, 18 490 participants from

The Environmental Determinants of Diabetes in the Young (TEDDY) Study: 2018 Update

Purpose of Review: The environmental triggers of islet autoimmunity leading to type 1 diabetes (T1D) need to be elucidated to inform primary prevention. The Environmental Determinants of Diabetes in the Young (TEDDY) Study follows from birth 8676 children with T1D risk HLA-DR-DQ genotypes in the USA, Finland, Germany, and Sweden. Most study participants (89%) have no first-degree relative with T1D

Multiple Late Holocene surges of a High-Arctic tidewater glacier system in Svalbard

Most large tidewater glaciers in Svalbard are known to have surged at least once in the last few hundred years. However, very little information exists on the frequency, timing or magnitude of surges prior to the Little Ice Age (LIA) maximum in ∼1900. We investigate the sediment-landform assemblages produced by multiple advances of the Nathorstbreen glacier system (NGS) in order to reconstruct its

Longitudinal monoaminergic PET imaging of chronic proteasome inhibition in minipigs

Impairment of the ubiquitin proteasome system has been implicated in Parkinson’s disease. We used positron emission tomography to investigate longitudinal effects of chronic intracerebroventricular exposure to the proteasome inhibitor lactacystin on monoaminergic projections and neuroinflammation. Göttingen minipigs were implanted in the cisterna magna with a catheter connected to a subcutaneous i

Ballistic tracks in graphene nanoribbons

High quality graphene nanoribbons epitaxially grown on the sidewalls of silicon carbide (SiC) mesa structures stand as key building blocks for graphene-based nanoelectronics. Such ribbons display 1D single-channel ballistic transport at room temperature with exceptionally long mean free paths. Here, using spatially-resolved two-point probe (2PP) measurements, we selectively access and directly ima

Expression of Pituitary Adenylate Cyclase-activating Peptide, Calcitonin Gene-related Peptide and Headache Targets in the Trigeminal Ganglia of Rats and Humans

Neurotransmitter and headache target localization in the trigeminal ganglia (TG) might increase the understanding of sites of action, and mechanisms related to headache therapy. The overall aim of the study was to investigate the presence of migraine targets in the TG with particular emphasis on pituitary adenylate cyclase-activating peptide (PACAP) and calcitonin gene-related peptide (CGRP), know

Impact of Exercise on Hemophilia

Sports and strenuous exercise have traditionally been discouraged for people with hemophilia (PWH) because of the perceived risk of bleeding. In this review, studies investigating the pros and cons of exercise are presented, and although most studies are of low validity, the randomized trials that do exist tell us that PWH benefit from exercise in terms of improved muscular function, endurance, an
