Artificial neural networks (ANNs) are employed to predict the energy levels of quantum systems, including the hydrogen atom, the harmonic oscillator, and the particle in a box, using various activation functions. The results demonstrate that the choice of activation function significantly influences prediction accuracy. This data-driven framework provides a powerful alternative to explicitly solvi
In a high-energy physics data analysis, the term “fake” backgrounds refers to events that would formally not satisfy the (signal) process selection criteria, but are accepted nonetheless due to mis-reconstructed particles. This can occur, e.g., when leptons from secondary decays are incorrectly identified as originating from the hard-scatter interaction point (known as non-prompt leptons), or when
How do political blocs form, consolidate, and dissolve? And can we trace these dynamics through the language of parliamentary debate? We address these questions by analyzing speeches in the Swedish Riksdag, using supervised machine learning to examine changes in rhetorical alignment among parties. Adapting classification methods developed for two-party systems to a multiparty context, we assess rh
In this work, we investigate carrier recombination dynamics and defect-related emission behavior in high-indium content InGaN platelets containing a single quantum well (QW) and a transition layer (TL) using temperature-dependent monochromatic cathodoluminescence (CL) imaging and time-resolved CL (TRCL). At low temperature, monochromatic CL imaging reveals expanded apparent emitting area of both l
Residues of pesticides require efficient and selective sample preparation, due to their existence in trace levels and the complex nature of food matrices. The objective of this study was to use a multivariate experimental design for the determination of multi-residue pesticides in the green coffee beans utilizing supercritical carbon dioxide (sc-CO2) as extraction solvent. In this study, an extrac
Visual dysfunction is increasingly recognized as an important feature of Alzheimer’s disease, and substantial retinal changes have been documented across multiple studies. Yet the molecular changes underlying retinal neurodegeneration and which retinal protein signatures best track cerebral pathology remain incompletely defined. Here, we performed comprehensive mass spectrometry-based proteomics o
Accurate rainfall data is essential for understanding the water cycle and monitoring climate change. However, precipitation estimates from satellite-only retrievals such as the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG) Early Run (IMERG-E), often contain large errors. These errors limit their usefulness for scientific studies and practical applications. To a
BACKGROUND: Large-scale migration of health workers from low-income countries continues to undermine health system capacity, particularly in contexts characterised by fiscal constraint and donor dependence. While retention incentives are widely used to mitigate attrition, their ability to offset international wage differentials remains contested. Zimbabwe provides a salient case, having implemente
Loess deposits in the Vojvodina region of northern Serbia are among the oldest and most complete loess-paleosol sequences in Europe to date. These thick sequences contain a detailed paleoclimatic record from the late Early Pleistocene. The correlation of detailed magnetic susceptibility records from Vojvodina with the Chinese loess record and deep-sea isotope stratigraphy provides some significant
Home oxygen therapy is a well-accepted treatment for advanced respiratory disease; however, there are substantial evidence gaps and implementation challenges. The patient experience varies widely; oxygen therapy devices are often poorly matched to patient needs; and adherence is suboptimal. Recent clinical trials have failed to demonstrate positive outcomes of home oxygen therapy across a range of
Många organister brottas med ergonomiska utmaningar kopplat till kroppshållningen. I detta arbete redogörs för orgelns särskilda svårigheter och vad olika källor säger om hur viktig ryggens position är, samt hur man på sikt kan förbättra sin hållning. Därefter genomfördes ett orgel-specifikt styrketräningsprogram utformat av P. J. Hawkins. Detta träningsprogram ledde på sex veckor fram till en märMany organists struggle with ergonomy in regard to posture. This paper presents the particular difficulties with organ-playing, views from different sources on the position of the back and how it can affect the musical flow of the performer, as well as how one can improve their posture over time. From here, an organ-specific strength training routine, as designed by H. J. Hawkins, was carried out,
I detta arbete testades övningsmetoder för att förbättra den musikaliska fraseringen. Metoden bestod av att med hjälp av sång, taktering, gestikulering och planerade andningar öva fraser utan instrument. Syftet var att effektivisera övningen utan fysisk ansträngning samt ge en ökad förståelse för vad det innebär att frasera musik. Resultatet visar att övning utan instrument var hjälpsamt för fraseIn this thesis, practice methods were tested to improve musical phrasing. The methods consisted of practicing phrases without instrument using singing, conducting, gesturing and planned breathing. The aim was to make the practice more efficient without physical effort and to provide increased understanding of what it means to phrase music. The results show that practicing without instrument was he
Detta arbete undersöker hur treklanger kan användas och expanderas för att generera voicings som fångar ett sound som jag inspireras av. Metoden är praktikbaserad och bygger på systematisk utforskning vid pianot, där treklangsbaserade voicings, add-strukturer och polyackord har genererats, testats och kategoriserats utifrån konsonans och dissonans genom både upplevd och teoretisk analys. ResultateThis study explores how triads can be expanded and applied to generate voicings that capture a specific sound that inspires me. The method is practice-based and involves systematic exploration at the piano, where triad-based voicings, additive structures, and polychords have been generated, tested, and categorized according to consonance and dissonance through both theoretical and perceptual analy
This paper focuses on the process of transcribing for guitar the music written for vihuela and lute in the Renaissance. Its aim is to highlight the benefits for the transcriber of engaging in this kind of work and to explore both the challenges one faces in the process and some of the options one has when presenting this music in modern notation. It concludes that the craft of transcribing is simu
Syftet med arbetet är att undersöka hur orgelackompanjemang till gregoriansk sång kan utformas för att passa olika konstellationer av sångare, till exempel församling, kör eller solist. Det görs genom att jämföra orgelsatser med utgångspunkt i Svenska kyrkans handböcker och olika egenkomponerade ackompanjemang. Data samlades in dels genom en kvalitativ intervju med gregorianikvetaren Anders EkenbeThe purpose of this work is to investigate how to form an organ accompaniment of Gregorian chant or plainchant to suit different constellations of singers, such as congregations, choirs or soloists. This is done by comparing organ parts in present day service books of Church of Sweden to accompaniments composed by the author. Data was collected from a qualitative interview with the chant expert An
