Charge balance functions reflect the evolution of charged pair correlations throughout the stagesof pair production, dynamical diffusion, and hadronization in heavy-ion collisions. Microscopic mod-eling of these correlations in the full collision volume shows that the balance functions are sensitiveto the diffusivity of light quarks when studied as functions of relative azimuthal angle. By restr
A broad range tagging spectrometer together with a new beam transport system for photonuclear experiments at the MAX-laboratory in Lund is described. The spectrometer consists of a quadrupole followed by an Elbek-type dipole and has a large momentum acceptance. It can produce both polarized and unpolarized tagged photons in the energy range 10–80 MeV with an energy resolution of about 300 keV.
With laser iridotomy it may often be difficult to achieve total penetration of the iris, particularly in very light or very dark irides. It may be impossible to determine with the slit-lamp whether a small laser iridotomy is functionally penetrating. We describe a straightforward method to test iridotomies for aqueous flow patency. Transcorneally introduced fluorescein is used to delineate any aqu
This report presents the sixth version of the European Grassland Butterfly Indicator, one of the EU biodiversity indicators of the European Environment Agency.The indicator is based on more than 9200 transects in national Butterfly Monitoring Schemes covering 22 countries across Europe, most of them active in the European Union. In 2015, counts were made in more than 4500 transects.Butterflies rep
While traditional forms of urban planning are oriented towards the future, the recent turn towards experimental and challenge-led urban developments is characterized by an overarching presentism. We explore in this article how an experimental approach to urban planning can consider the long-term through setting-up ‘conversations with a future situation.’ In doing so, we draw on a unique experiment
Decision and Value of Information analyses can be highly computational demanding due to the exponential growth of the decision tree in dependency of the state and decision variables. Due to the advancement of computational methods in the last decades, decision problems with moderate complexity maybe solved by a software tool whereas highly complex analyses require tailored approaches, algorithms a
Public procurement accounts for a very large share of most economies worldwide. This conceptual article argues that the key to achieving more innovations when pursuing public procurement is to describe problems to be solved or functions to be fulfilled (functional procurement) instead of describing the products to be bought (product procurement). Contracting authorities need to identify the proble
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The objective of this review is to assess benefits and harms of postnatal administration of corticosteroids for the management of transient tachypnea of the newborn.
Regression testing is a means to assure that a change in the software, or its execution environment, does not introduce new defects. It involves the expensive undertaking of rerunning test cases. Several techniques have been proposed to reduce the number of test cases to execute in regression testing, however, there is no research on how to assess industrial relevance and applicability of such tec
Water resources face risks due to water use stress and water scarcity. Collective and integrated actions by different institutions and stakeholders are needed to reduce future water risks. This paper aimed to assess the potential for a water stewardship partnership in River Nzoia Basin to reduce future water risks facing the ecosystem, agriculture, and other sectors by quantifying water risks and
The testing method proposed in the Cleanroom methodology is Statistical Usage Testing. This testing technique is based on that the test cases represent theoperational profile. The failure data from testing is then used in a software reliability model to certify the reliability of the software. This paper introduces a new model for modelling the usage of the system, i.e. the operational profile. It
