Comparative study of the heavy-quark dynamics with the Fokker-Planck equation and the Plastino-Plastino equation

The Fokker-Planck Equation (FPE) is a fundamental tool for the investigation of kinematic aspects of a wide range of systems. The Plastino-Plastino Equation (PPE) is the correct generalization describing the kinematic evolution of complex systems consistent with q-statistics. In the present work, we use this particular problem to compare the results obtained with the FPE and the PPE, and discuss t

Motivation för lärande. Pedagogisk kommunikation utifrån ett sociokulturellt perspektiv

I den här undersökningen genomförs en analys av vetenskaplig litteratur i syfte att finna ett svar på en fråga nämligen om hur kommunikation påverkar motivation för lärande. Under undersökningens gång analyseras vetenskaplig experimentell forskning där människans motivationssfär betraktas utifrån ett sociokulturellt perspektiv. Den här undersökningens resultat visar att emotionella aspekter har en

Predicting Tennis Match Results Using Classification Methods

This paper aims to contribute to the increasing popularity of machine learning in sports by predicting the winner in a tennis match using classification methods. The dataset used in this study spans a 10-year period and includes ATP singles matches from 2012 to 2022, with up to 49 explanatory variables. Six regression-based models were constructed and tested, all of which achieved an accuracy of a

Forecasting Swedish FCR-D Prices using Penalized Multivariate Time Series Techniques

The Swedish energy market is becoming more and more sustainable, with an increasing volume and number of diversified energy sources being continuously added to the mix. To stabilize the grid frequency, auctions are held to offer energy providers incentives to produce or consume energy on short notice. This paper is applying different multivariate time series models and their ensemble to find relia

To observe and evaluate sensemaking : The development of the sensemaking interaction analysis

Systematic evaluations are vital to support learning and enhance performance in a crisis response. There are quantitative methods available today for evaluating crisis response management (CRM), but there are limiting factors negatively affecting their potential; They often involve techniques difficult to implement in real events, lack reliability testing, provide outcomes questionable from a lear

Global distribution of DNA hydroxymethylation and DNA methylation in chronic lymphocytic leukemia

Background: Chronic lymphocytic leukemia (CLL) has been a good model system to understand the functional role of 5-methylcytosine (5-mC) in cancer progression. More recently, an oxidized form of 5-mC, 5-hydroxymethylcytosine (5-hmC) has gained lot of attention as a regulatory epigenetic modification with prognostic and diagnostic implications for several cancers. However, there is no global study

Mineral Deposits in Ficus Leaves : Morphologies and Locations in Relation to Function

Ficus trees are adapted to diverse environments and have some of the highest rates of photosynthesis among trees. Ficus leaves can deposit one or more of the three major mineral types found in leaves: amorphous calcium carbonate cystoliths, calcium oxalates, and silica phytoliths. In order to better understand the functions of these minerals and the control that the leaf exerts over mineral deposi

Impact of xylose epimerase on sugar assimilation and sensing in recombinant Saccharomyces cerevisiae carrying different xylose-utilization pathways

BackgroundOver the last decades, many strategies to procure and improve xylose consumption in Saccharomyces cerevisiae have been reported. This includes the introduction of efficient xylose-assimilating enzymes, the improvement of xylose transport, or the alteration of the sugar signaling response. However, different strain backgrounds are often used, making it difficult to determine if the findin

Emergency department crowding and mortality : an observational multicenter study in Sweden

Background: Emergency department (ED) crowding is a serious problem worldwide causing decreased quality of care. It is reasonable to assume that the negative effects of crowding are at least partially due to high staff workload, but previous crowding metrics based on high workload have not been generalisable to Swedish EDs and have not been associated with increased mortality, in contrast to, e.g.

AI och risker för diskriminering i arbetslivet

Många arbetsgivare känner inte till att de redan idag använder sig av artificiell intelligens, AI, eller annat automatiserat beslutsfattande. Det visar den rapport om AI och risker för diskriminering i arbetslivet som Diskrimineringsombudsmannen, DO, publicerar idag. Att arbetsgivare har denna kunskap är avgörande för att arbeta förebyggande för att motverka diskriminering vid tillämpning av tekni

Avian Haemosporidians Infecting Short- and Long-Distance Migratory Old World Flycatcher Species and the Variation in Parasitaemia After Endurance Flights

Purpose: Avian haemosporidians are widespread parasites, occurring in many bird families and causing pathologies ranging from rather benign infections to highly virulent diseases. The state of knowledge about lineage-specific intensities of haemosporidian infection (i.e., parasitaemia) is mainly based on infection experiments conducted under laboratory conditions. The levels and range of parasitae

Optimization-based attack against control systems with CUSUM-based anomaly detection

Security attacks on sensor data can deceive a control system and force the physical plant to reach an unwanted and potentially dangerous state. Therefore, attack detection mechanisms are employed in cyber-physical control systems to detect ongoing attacks, the most prominent one being a threshold-based anomaly detection method called CUSUM. Literature defines the maximum impact of stealth attacks

Environmental determinants of body mass index trajectories: results from a longitudinal Swedish study

Exposure to natural environments is thought to benefit mental and physical health. A better understanding of the interplay between the individual and the environment in relation to public health is imperative in light of the joint biodiversity, climate, and health crises. This study aimed to 1) identify Body Mass Index (BMI) trajectories in the Scania Public Health Cohort (SPHC), 2) characterise t

Träbalks hållfasthet vid rätvinklig urtagning

Decomposing Import Price Inflation in the EU

This thesis examines what drives import price inflation in the EU by decomposing it into supply and demand driven inflation. The decomposition is done by using product level import data retrieved from Eurostat. The paper examines the period from 2019-01 to 2023-01 which captures events such as the Covid-19 and the war in Ukraine. To classify the product as demand or supply driven, two methods are

Operationssjuksköterskans självupplevda kompetens vid positionering av patienter i litotomiläge - En kvantitativ och kvalitativ enkätstudie

Background: The lithotomy position is one of the four most common positions during surgical procedures. This position is very vulnerable for the patient and can lead to several different types of complications. To ensure a safe positioning the preoperative assessment and preparations requires an OR nurse’s specialist competence. The aim: The aim was to examine if OR nurses’ years of experience aff
