The fundamental principle of investing, applicable at both systematic and individual levels, is the art of balancing the portfolio between expected returns and acceptable risk exposure. Risk management involves predicting the direction of the underlying asset’s movement and taking appropriate actions accordingly. Traditionally, statistical models such as GARCH have been used to achieve this object
The steel industry is one of the most polluting industries globally. There exists an EU waste shipment proposal that aims to restrict the EU export of waste in order to raise safe, environmental standards and circularity within the EU. Under this proposal, steel scrap is defined as waste and since the EU is the largest exporter of steel scrap globally, this has implications for the EU steel indust
Knitting is a craft that has existed for many years giving it a rich history. The popularity of knitting has never been steady and has risen and fallen throughout the years, albeit now readily associated with older generations. It is safe to say that knitting is currently going through a revival in Denmark, especially young women have picked it up, seemingly taking the popularity of knitting to ne
Den fysiska delen av att spela ett brassinstrument jämförs ibland med idrottsutövande i termer av muskelstyrka och uthållighet. Precis som för en idrottsutövare kan uppkomsten av en skada bli förödande för en musikers karriär. Med anledning av detta väcks flera frågor om vilka arbetssätt som kan användas i undervisningen för att förebygga skador samt vad som går att göra om skadeförloppet är långtThe physical aspects of playing the trumpet are sometimes compared to practicing sports in terms of strength and stamina. Just like injuries may cause big problems to athletes, an injury could be devastating to a musician's career. With this taken into consideration, several questions come to my mind about which teaching methods that can be used to prevent injuries and what a teacher can do if
Vi vet idag att en omställning av transportsektorn är avgörande för uppfyllandet av de klimatpolitiska målen och FN:s 2030-mål. Såväl forskare som praktiker har därför framhävt behovet av att öka andelen energieffektiva transportslag som gång, cykel och kollektivtrafik. Samtidigt pågår det idag en snabb teknikutveckling inom transportområdet och idag sker mycket av innovationsarbetet genom offentl
INTRODUCTION: Current pharmacological treatments of post-traumatic stress disorder (PTSD) have limited efficacy. Although the diagnosis is based on psychopathological criteria, it is frequently accompanied by somatic comorbidities and perhaps "accelerated biological aging," suggesting widespread physical concomitants. Such physiological comorbidities may affect core PTSD symptoms but are rarely th
INTRODUCTION: Numerous prior studies, even from countries with free access to care, have associated long travel time to care with poor survival in patients with colorectal cancer. METHODS: This is a data-linkage study of all 3718 patients with colorectal cancer, diagnosed between 2007 and 2013 in Northern Sweden, one of the most sparsely populated areas in Europe. Travel time to nearest hospital w
The potential benefit of nonpharmacological adjunctive therapy is not well-studied following major abdominal surgery. The aim of the present study was to investigate transcutaneous electrical nerve stimulation (TENS) as a complementary nonpharmacological analgesia intervention during weaning from epidural analgesia (EDA) after open lower abdominal surgery. Patients were randomized to TENS and sham
A search for direct pair production of scalar partners of the top quark (top squarks or scalar third-generation up-type leptoquarks) in the all-hadronic tt¯ plus missing transverse momentum final state is presented. The analysis of 139 fb - 1 of s=13 TeV proton–proton collision data collected using the ATLAS detector at the LHC yields no significant excess over the Standard Model background expect
A search is presented for anomalous quartic gauge boson couplings in vector-boson scattering. The data for the analysis correspond to 20.2 fb-1 of s=8 TeV pp collisions and were collected in 1972 by the ATLAS experiment at the Large Hadron Collider. The search looks for the production of WW or WZ boson pairs accompanied by a high-mass dijet system, with one W decaying leptonically and a W or Z dec
A search for dark matter (DM) particles produced in association with a hadronically decaying vector boson is performed using pp collision data at a centre-of-mass energy of s=13 TeV corresponding to an integrated luminosity of 36.1 fb−1, recorded by the ATLAS detector at the Large Hadron Collider. This analysis improves on previous searches for processes with hadronic decays of W and Z bosons in a
BACKGROUND: Traumatic brain injury (TBI) and spinal cord injury (SCI) are increasingly recognised as global health priorities in view of the preventability of most injuries and the complex and expensive medical care they necessitate. We aimed to measure the incidence, prevalence, and years of life lived with disability (YLDs) for TBI and SCI from all causes of injury in every country, to describe
Remote sensing is increasingly being used as a cost-effective and practical solution for the rapid evaluation of impacts from wildland fires. The present study investigates the use of the support vector machine (SVM) classification method with multispectral data from the Advanced Spectral Emission and Reflection Radiometer (ASTER) for obtaining a rapid and cost effective post-fire assessment in a
This paper presents and discusses a recently digitized, dataset of strikes and lockouts in Sweden for the period 1859-1902. The dataset, which originally was collected by Axel Raphael by retrospectively browsing through newspapers, pre-dates the Swedish official statistics on work stoppages that began in 1903. Whereas Raphael’s data have been used to illustrate the long-run development of strikes,
Objective: Modality and frequency of image-based renal cell carcinoma (R.C.C.) follow-up strategies are based on risk of recurrence. Using the R.E.C.U.R.-database, frequency of imaging was studied in regard to prognostic risk groups. Furthermore, it was investigated whether imaging modality utilized in contemporary follow-up were associated with outcome after detection of recurrence. Moreover, out
Atrial fibrillation (AF) is a common disease with a high prevalence in the adult population. Treatment of AF encompasses antiarrhythmic drugs and catheter ablation to reduce symptoms. The aim of this thesis was to study how to best alleviate symptoms of AF in a safe and efficient way comparing pharmacological treatment and the two dominating catheter ablation techniques, cryoballoon (CRYO) ablatio
PurposeIt is not known if mammographic breast compression of a primary tumor causes shedding of tumor cells into the circulatory system. Little is known about how the detection of circulating biomarkers such as circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA) is affected by breast compression intervention.MethodsCTCs and ctDNA were analyzed in blood samples collected before and afte
Stem cells are unspecialized cells able to divide and produce copies of themselves and having the potential to differentiate, i.e. to produce other cell types in the body. Because of the latter ability, the scientists investigate their possible use in regenerative medicine. Especially embryonic stem cells have huge therapeutic potential because they can give rise to every cell type in the body as
