Objectives. To clarify if an adaptive current stimulation protocol, in which current amplitude is modulated during continuous stimulation, provides better efficacy than constant current stimulation protocol with respect to analgesia caused by individualized stimulation in rat periaqueductal gray matter (PAG) /dorsal raphe nuclei (DRN). Approach. Ultrathin microelectrodes adapted for recording (n =

Recent years have seen dramatic improvements in computer power, allowing ever more challenging problems to be approached. In light of this, it is imperative to have a quantitative model for examining chemical reactivity, both in the condensed phase and in solution, as well as to accurately quantify physical organic chemistry (particularly as experimental approaches can often be inconclusive). Simi

Coherent synchrotron radiation (CSR) is generated when the electron bunch length is in the order of the magnitude of the wavelength of the emitted radiation. The self-interaction of short electron bunches with their own electromagnetic fields changes the longitudinal beam dynamics significantly. Above a certain current threshold, the micro-bunching instability develops, characterized by the appear

E-poster, 2-minute presentation. ABSTRACT: Background: A study of typically developing infants testing joystick-operated powered wheelchair was part of the Driving to Learn project. The original aim was to find a pattern in achievements among participants with profound cognitive disabilities by comparing with young infants. Method: Re-analysis of video-data collected with typically developing infa

The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. The two parts are linked together with a glucoside bond. In nature, the building and breakage of a glu

Background: Collegial midwifery assistance during the active second stage of labor that involves a second midwife being present has been shown to reduce severe perineal trauma (SPT) by 30%. The aim of this study was to investigate primary midwives' experiences of collegial midwifery assistance with the purpose of preventing SPT during the active second stage of labor. Methods: This study uses an o

Boreal forests and peatlands store over 30% of the global terrestrial carbon in their vegetation and soil. but changing climate can compromise the current carbon stock. Rising air temperatures, changing precipitation patterns and increased risk of natural disturbances can impact the ability of the boreal ecosystems to absorb and store carbon, reducing their effectiveness as carbon sinks. Reliable

The experimental power of a granddaughter design to detect quantitative trait loci (QTL) in dairy cattle is often limited by the availability of progeny-tested sires, by the ignoring of already identified QTL in the statistical analysis, and by the application of stringent experimentwise significance levels. This study describes an experiment that addressed these points. A large granddaughter desi

Bayesian optimization (BO) has become an established framework and popular tool for hyperparameter optimization (HPO) of machine learning (ML) algorithms. While known for its sample-efficiency, vanilla BO can not utilize readily available prior beliefs the practitioner has on the potential location of the optimum. Thus, BO disregards a valuable source of information, reducing its appeal to ML prac

This study aimed to examine associations of dietary quality and diversity among reproductive-aged women with overweight and obesity. We conducted a cross-sectional study in the Health and Demographic Surveillance System of the Dar es Salaam Urban Cohort Study (DUCS) in Tanzania. A random sample of 1004 non-pregnant women was selected from the DUCS population database and interviewed about dietary

In this paper we consider the problem of relative pose estimation from two images with per-pixel polarimetric information. Using these additional measurements we derive a simple minimal solver for the essential matrix which only requires two point correspondences. The polarization constraints allow us to pointwise recover the 3D surface normal up to a two-fold ambiguity for the diffuse reflection.

Seasonality of dinoflagellate blooms and dinoflagellate assemblies are not random. Yet, bloom events and the specific appearance of species is difficult to predict and sometimes appears stochastic. Nevertheless, it has been established that both abiotic and biotic factors determine species assemblies, as well as the available species pool. The physical environment, especially nutrients and mixing/

The Fertile Desert studies a region of the Euphrates Valley between the Balikh and Khabour in Syria that remains little known. Partial reports, isolated interventions, and proposals for a hypothetical reconstruction of the relationship and processes of cultural expansion between Mesopotamia and the Jazira suggest that the Euphrates has always been a major traffic route. But suggestions on a map mu

Genetic variations have a multitude of effects on proteins. A substantial number of variations affect protein–solvent interactions, either aggregation or solubility. Aggregation is often related to structural alterations, whereas solubilizable proteins in the solid phase can be made again soluble by dilution. Solubility is a central protein property and when reduced can lead to diseases. We develo

Short-term tourists visiting formerly residential areas are a potential source of conflict as the short-term tourists change the place they are visiting and represent an inconvenience to residents. This research uses a mixed methods approach with the short-term rent gap framework introduced by Wachsmuth and Weisler (2018) as the quantitative and an additional online expert interview as the qualita

I en bransch som i allt större utsträckning präglas av hållbarhet och miljö, blir det allt viktigare att hitta sätt att återvinna och återanvända snarare än att nyproducera. Ett exempel på detta är när det kommer till de obundna lagren, bär- och förstärkningslager i vägöverbyggnaden. Till dessa används traditionellt bergkross och naturgrus, som bryts från bergtäkter. Dessa material är inte oändligIn an industry that is increasingly affected by sustainability and environmental matters, it is becoming more and more important to find ways to recycle and reuse materials rather than producing new materials. An example of this is when it comes to unbound pavement materials, such as the base and subbase layers. For these layers, mineral aggregate and natural gravel is traditionally used, which ar

The aim of this study was to explore social workers’ experiences with the assessment tool UngDOK at Maria clinics in Skane. The past 30 years has seen a rise in popularity of evidence based practices and increased requirements for scientific evidence of the effects of various treatments. Several manual based evaluation and assessment instruments have been implemented in the field of social work in

Sveriges vattenledningsnät kräver kontinuerliga och stora in- vesteringar och måste underhållas på ett effektivt sätt; syftet med den här studien var därför att utröna vilka ledningsattribut som är viktigast för att i en ANN-modell identifiera ledningar med hög risk för läckage. Detta gjordes genom att först använda attri- buturvalsmetoderna ReliefF och Recursive Feature Elimination (RFE) tillsammanSweden’s water pipe network demands continuous and large investments and must be maintained in an effective way; the aim with this study was therefore to investigate which pipe features are most important to identify pipes with a high risk of leakage in an ANN-model. This was done by first utilizing the feature selection methods ReliefF and Recursive Feature Elimination (RFE) with Random Forest Clas

Människan har alltid försökt förklara de naturfenomen som vi omgivs av med olika tankesätt och teorier. Den bästa nuvarande beskrivningen av universum kallas Standardmodellen, och är en beskrivning av världens fundamentala byggstenar och hur de interagerar med varandra. Även om Standardmodellen ofta fungerar oroväckande bra finns det många fenomen i vårt universum den inte kan förutsäga. Detta inkAbstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. This thesis presents three projects conducted within the ATLAS Same-Sign Dilepton gr
