Retinal implant devices are becoming an increasingly realizable way to improve the vision of patients blinded by photoreceptor degeneration. As an electrode material that can improve restored visual acuity, carbon nanotubes (CNTs) excel due to their nanoscale topography, flexibility, surface chemistry, and double-layer capacitance. If vertically aligned carbon nanotubes (VACNTs) are biocompatible
The European Spallation Source Neutrino Super Beam (ESSνSB) project aims at a discovery of leptonic CP violation with a precise measurement of the CP phase angle. ESSνSB is characterized by an intense neutrino beam to be produced at ESS by a 5-MW proton beam, and the placement of the far detector at the second oscillation maximum. The aims of the near detector for ESSνSB are neutrino flux and inte
Thefirst reported applications of laser sheet imaging for the study of atomizing sprays date from the mid 1980th.Since those early tries, blurring effects from the light being scattered multiple times by the surrounding dropletswere already observed and reported. While s trategies in suppressing part of this multiple light scatteringcontribution, were known for transmission imaging (e. spatial Fou
Pythia8 is the only general purpose event generator able to produce complete fully exclusive hadronic final states in collisions involving heavy ions. The model that allows this is called Angantyr and will be discussed in this contribution. The contribution also discusses models based on interactions between strings in an extention of the Lund model that are able to describe some collective effect
We investigate stability issues for steady states of the spherically symmetric Einstein-Vlasov system numerically in Schwarzschild, maximal areal, and Eddington-Finkelstein coordinates. Across all coordinate systems we confirm the conjecture that the first binding energy maximum along a one-parameter family of steady states signals the onset of instability. Beyond this maximum perturbed solutions
Entropy production is a key concept of thermodynamics and allows one to analyze the operation of engines. For the Scovil-Schulz-DuBois heat engine, the archetypal three-level thermal maser coupled to thermal baths, it was argued that the common definition of heat flow may provide negative entropy production for certain parameters [Boukobza and Tannor, Phys. Rev. Lett. 98, 240601 (2007)PRLTAO0031-9
A search for heavy resonances decaying into a pair of Z bosons leading to ℓ+ℓ-ℓ+ℓ- and ℓ+ℓ- final states, where ℓ stands for either an electron or a muon, is presented. The search uses proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb - 1 collected with the ATLAS detector during 2015 and 2016 at the Large Hadron Collider. Differe
MAX IV-laboratoriet är en anläggning med syfte att producerasynkrotronljus till forskning. När laddade partiklar accelereras skickar de ut energi i form av strålning kallad synkrotronljus. Synkrotronljus är intensivt ljus med många olika våglängder och är därför väldigt användbart för att studera strukturer och processer inom många olika fält såsom materialforskning, medicin, geologi och arkeologiThe MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. The 3 GeV ring is the first of a new generation of synchrotron light storagering
This article presents a comprehensive integration of current experimental evidence and theories about so-called parapsychological (psi) phenomena. Throughout history, people have reported events that seem to violate the common sense view of space and time. Some psychologists have been at the forefront of investigating these phenomena with sophisticated research protocols and theory, while others h
Article 83(2) TFEU, introduced by the Treaty of Lisbon, confers a power on the EU to harmonise Member States’ legislation to define criminal offences and criminal sanctions. Nonetheless, uncertainty persists as to whether this provision exhaustively determines the EU’s power to adopt criminal law to enforce its policies. The article outlines the core case for viewing art.83(2) TFEU as a lex specia
Over the last two decades the market for membrane technology in the food industry increased to a market volume of approx. € 50 million and is now the second largest industrial market for membranes after municipal water treatment in Germany. The key membrane technologies in the food industry are the pressure driven membrane processes; microfiltration, ultrafiltration, nanofiltration and reverse os
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti
The durability of wood depends on its in-use environmental conditions. The aim of this study was to estimate the effects associated with macro climate and detail design as well as their interdependence. A numerical moisture model and two different decay prediction models were utilized for assessing the decay risk of a horizontal member and a joint exposed at 300 sites scattered across Europe. In g
Aim: The role of migratory birds in the spread of parasites is poorly known, in part because migratory strategies and behaviours potentially affecting transmission are not easy to study. We investigated the dynamics of infection by blood parasites through the annual cycle of a long-distance Nearctic–Neotropical migratory songbird to examine the role of this species in dispersing parasites between
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk-outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk-outcome pairs, and new data
The purpose of this thesis is to find out whether or not the Estonian stock market is developed enough for introduction of a market for standardized options on index and stocks. This will be conducted through comparing the stock market development in Estonia today with the corresponding situation in Denmark, Hungary and Norway at the time of their introduction of trade in standardized options. Our
