BACKGROUND: Positive photopatch test reactions are classified according to the International Contact Dermatitis Group. The various reaction patterns are interpreted to represent patterns such as contact allergy, photocontact allergy, photoaugmentation, and photoinhibition. OBJECTIVE: To investigate whether there are any weaknesses in the interpretation of reaction patterns. MATERIALS & METHODS
BACKGROUND: Patients with nonischemic dilated cardiomyopathy (DCM) may be at lower risk for ventricular arrhythmias compared with those with ischemic cardiomyopathy (ICM). In addition, DCM has been identified as a predictor of positive response to cardiac resynchronization therapy (CRT).OBJECTIVES: The aim of this study was to investigate the impact of an additional implantable cardioverter-defibr
The main aim of this work is to construct several new families of proper biharmonic functions defined on open subsets of the classical compact simple Lie groups SU(n), SO(n) and Sp(n). We work in a geometric setting which connects our study with the theory of submersive harmonic morphisms. We develop a general duality principle and use this to interpret our new examples on the Euclidean sphere S^3
Att silver har en bakteriedödande effekt har varit känt sedan många århundraden. Historien om silver sträcker sig ända tillbaka till 4000 år före Kristus då de antika Kaldeérna använde silver och det var på den tiden en av mest använda metallerna tillsammans med guld och koppar. Persiska kungar föredrog att dricka vatten endast från bägare gjorda av silver för att vattnet kunde bevaras friskt och Over the past decade, a massive increase in the use of nanomaterials and nanoparticles (NPs) in both commercial and medical applications has occurred. Medical applications include advanced drug delivery vehicles, imaging and hyper thermic therapies. In retinal research, several nanomaterials have been explored in novel treatment approaches, ranging from metals, carbon, polymers and silica to biolo
In this paper we consider random distance graphs motivated by applications in neurobiology. These models can be viewed as examples of inhomogeneous random graphs, notably outside of the so-called rank-1 case. Treating these models in the context of the general theory of inhomogeneous graphs helps us to derive the asymptotics for the size of the largest connected component. In particular, we show t
Visioner och framtidsbilder efterfrågas ofta för att motivera och inspirera till samhälleliga förändringar. Sådana visioner kan bygga på politisk förändring eller måla upp bilder av teknisk utveckling som hjälper oss att lösa svåra samhälleliga problem. Den typen av visioner är kanske speciellt viktiga när vi strävar efter en hållbar utveckling, och framför allt ifall vi vill motverka att jordens Different kinds of representations of the future are often asked for in order to motivate and inspire societal change. These envisioned futures can be based on political or behavioural change, or may visualize technical developmentwhich could help us solve complex societal problems. The latter type of epresentation is especially important if we aim for sustainable development, and even more so if
The combined quantum mechanical (QM) and molecular mechanical (MM) approach (QM/MM) is a popular method to study reactions in biochemical macromolecules. Even if the general procedure of using QM for a small, but interesting part of the system and MM for the rest is common to all approaches, the details of the implementations vary extensively, especially the treatment of the interface between the
Background: Knee arthroscopy is one of the most common surgical procedures worldwide and the number of arthroscopies has substantially increased in the last 30 years. Thus, our aim was to provide updated estimates on the risk of complications and compare it with the background risk in the general population. Methods: We identified patients aged 15-84 years with knee arthroscopy in the years 2005-2
Obesity is closely associated to several diseases such as type 2 diabetes, cardiovascular disease, hepatic steatosis, airway disease, neurodegeneration, biliary diseases and certain cancers. It is, therefore, of importance to assess the role of nutrition in disease prevention as well as its effect in the course of such pathologies. In the present study, we addressed the impact of the exposure to d
Taking advantage of the storage ring free electron laser beamline at Elettra, we have implemented an experimental setup for the generation of sub-picosecond (ps) coherent optical pulses in the VUV range. The setup is based on the frequency up-conversion of a high-power external signal (provided by a Ti:Sapphire laser) and makes use of a relativistic electron bunch as resonating medium. The produce
Remarkable flight performance is key to the survival of adult Odonata. They integrate varied three-dimensional architectures and kinematics of the wings, unsteady aerodynamics, and sensory feedback control in order to achieve agile flight. Therefore, a diverse range of approaches are necessary to understand their flight strategy comprehensively. Recently, new data have been presented in several ke
Circumplanetary discs (CPDs) form around young gas giants and are thought to be the sites of moon formation as well as an intermediate reservoir of gas that feeds the growth of the gas giant. How the physical properties of such CPDs are affected by the planetary mass and the overall opacity is relatively poorly understood. In order to clarify this, we use the global radiation hydrodynamics code FA
This article uses a socio-legal perspective to analyse the use of ethics guidelines as governance tool in the development and use of artificial intelligence (AI). This has become a central policy area in several large jurisdictions, including China and Japan, as well as the EU, focused here. Particular emphasis is in this article placed on the Ethics Guidelines for Trustworthy AI published by the
Using synchronized rapid video imaging and calibrated acoustic emission (AE) measurements, a direct correspondence is found between the length of emerging twin and its AE transient response during in-situ testing of Mg polycrystals. The detectability limit for twin nucleation in Mg and its alloys is evaluated to be as small as 0.3 µm or even less. It is shown that the use of appropriate calibratio
Theoretical investigations of the structure and function of the blue copper proteins are described. We have studied the optimum vacuum geometry of oxidised and reduced copper sites, the relative stability of trigonal and tetragonal Cu(II) structures, the relation between the structure and electronic spectra, the reorganisation energy, and reduction potentials. Our calculations give no support to t
