Multicentre patch test studies (MPTSs) can contribute useful information for diagnostic and preventive measures. The aim of the present paper is to propose how to perform high-quality MPTSs. To this end, factors of significance for the patch test result are discussed with regard to the standardization and calibration of high-quality MPTSs. The 16 factors discussed are scored 0, 1, 2, or 3, dependi

How are public spaces regulated in tourist cities? In this doctoral dissertation I seek to answer this question by exploring the intersections between urban tourism and public space regulation. I argue that public space regulation substantially differs from the tourist to the non-tourist zone. This thesis contradicts the common belief that public space regulation may vary from city to city, but re

Sleep problems, in particular the difficulty in initiating and maintaining sleep are important comorbidities in children and adolescents with attention deficit hyperactivity disorder (ADHD), accompanied by a range of negative consequences for both patients and their caregivers. Melatonin, a naturally occurring hormone that is important for coordinating the body's sleep-wake cycle, has been used to

Remote automated surveillance of insect abundance and diversity is poised to revolutionize insect decline studies. The study reveals spectral analysis of thin‐film wing interference signals (WISs) can discriminate free‐flying insects beyond what can be accomplished by machine vision. Detectable by photonic sensors, WISs are robust indicators enabling species and sex identification. The first quant

The formation of cesium lead bromide (CsPbBr3 ) nanocrystal superlattices (NC SLs) is accompanied by a red shift in the NC photoluminescence (PL). The values of the PL red shift reported in the literature range from none to 100 meV without unifying explanation of the differences. Using a combination of confocal PL microcopy and steady-state

We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measurements from FIES@NOT, HARPS-N@TNG, and the coudé spectrograph on the McDonald Observatory 2.7 m telescope. K2-29 b (EPIC 211089792b) transits a K1V star with a period of 3.2589263 ± 0.0000015 days; its orbit is slightly ecce

This Letter reports the observation of WZγ production and a measurement of its cross section using 140.1±1.2  fb^{-1} of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The WZγ production cross section, with both the W and Z bosons decaying leptonically, pp→WZγ→ℓ^{'}^{±}νℓ^{+}ℓ^{-}γ (ℓ^{(^{'})}=e, μ), is measured in a f

In modern ASIC verification, bridging the gap between IP-level and system-level test environments is a major challenge, especially as system-on-chip (SoC) complexity grows. This thesis presents a novel methodology leveraging the Accellera Portable Stimulus Standard to enable portable, reusable verification scenarios across these levels. The approach introduces a pre-runtime signal forcing mechanis

Diffusion magnetic resonance imaging (MRI) is a technique that utilizes the random thermal motion of water molecules to probe the microstructure of the tissue. Because it has excellent soft tissue contrast and high sensitivity to changes in the microstructure, it has established itself as a powerful tool to detect and quantify both normal development and pathological processes. Diffusion encoding

Tunnel structures play an important role in Sweden’s infrastructure. At shallow depths, a common construction method is the so-called “Cut-and-Cover” tunnel, where the tunnel placement is excavated, cast in concrete on-site, and then backfilled. Such tunnels are typically subjected to constant water pressure, which yields high demands on crack control. Cracking in elongated concrete structures oft

Sedan tillkomsten av den nuvarande rättegångsbalken på 1940-talet har utgångspunkten i svensk rätt varit att bevisprövningen ska vara fri och inte styrd av legala normer. Detta hindrade emellertid inte lagstiftaren från att i förarbetena ställa upp krav på att bevisprövningen skulle vara objektiv och analytisk. Som en följd därav utvecklades ett antal bevisprövningsmetoder i den juridiska doktrineSince the creation of the present Code of Judicial Procedure in the 1940s the basis in Swedish law has been a free sifting of evidence, which is not governed by legal norms. This, however, did not prevent the legislator from demanding in the preparatory works that the sifting of evidence should be objective and analytical. As a consequence thereof, a number of methods for sifting the evidence deve

Registration is a key component in multi-atlas approaches to medical image segmentation. Current state-of-the-art uses intensity-based registration methods, but such methods tend to be slow and sensitive to large amount of noise and anatomical abnormalities present in medical images. In this master thesis, a novel feature-based registration method is presented and compared to two baseline methods;

In this study, static coefficients of friction for laminated veneer lumber on steel surfaces were determined experimentally. The focus was on the frictional behaviors at different pressure levels, which were studied in combination with other influencing parameters: fiber orientation, moisture content, and surface roughness. Coefficients of friction were obtained as 0.10–0.30 for a smooth steel sur

Teknikutvecklingen, särskilt inom AI, har möjliggjort produktion av deepfakes, det vill säga artificiellt genererat eller manipulerat material som kan framstå som mycket autentiskt. Samtidigt har digitaliseringen medfört att digital bevisning fått en allt mer central roll i rättsprocesser. Detta aktualiserar nya rättsliga utmaningar, eftersom möjligheten att skapa övertygande falskt material riskeTechnological development, particularly within AI, has enabled production of so-called deepfakes, i.e., artificially generated or manipulated material that may appear highly authentic. At the same time, digitalisation has made digital evidence central in legal proceedings. This creates new legal challenges, since convincing false material may undermine the reliability of digital evidence. The pur

This essay provides an analysis of the relation between the value added tax (VAT) and the size of the informal sector in Africa. The proposed hypothesis is that due to incentive mechanisms provided by VAT, tax evasion, and hence the size of the informal sector, should decrease when VAT replaces other standard consumption taxes, primarily the retail sales tax (RST) and the turnover tax (TOT). The
