The purpose of this paper is to compare a collection of control variates for Monte Carlo-valuation of spread options on three assets with a view towards energy markets and to lay a foundation for continued research on control variates, e.g. combinations of control variates and adaption for quasi-Monte Carlo. The paper builds upon previous research on option pricing using Monte Carlo-simulation and

Around midnight of 9 January 1959, the Vega de Tera dam broke, releasing nearly 8 million cubic metres of water that destroyed the Spanish town of Ribadelago, killing 144 people. To this day, it remains the worst dam-related failure of the past two centuries of Spanish history. In this chapter we expand the time frame of the disaster, moving from a one-day narrative to focus on the processes of re

BACKGROUND: Achalasia is a rare motility disorder of the esophagus. The diagnosis involves clinical suspicion based on history details and results of high-resolution manometry (HRM) as recommended by the Chicago classification (CCv4.0). Interpreting data obtained through HRM can be complex especially for the novice user.METHODS: We propose therefore a color-based algorithm involving the "reversed

One of the main challenges as the market for fully commercial electrified vehicles quickly expands is predicting the electromagnetic interference (EMI) in traction voltage systems (TVSs) in differential mode (DM) and common mode (CM). The number of subsystems connected to vehicle TVSs is increasing, and thus, so are the electromagnetic compatibility (EMC) requirements. These requirements should ma

Occupancy is one of the primary contributors to the energy performance gap, defined as the difference between actual and predicted energy usage, in buildings. This paper limits its scope to residential buildings, where occupant-centric consumption often goes unaccounted for in standard energy metrics. This paper starts from the hypothesis that a simple occupant energy efficiency label is needed to

Aim of the review: To provide an overview of studies that have published dataregarding region and population size, procedure location, team composition, inclusionand exclusion criteria, outcome parameters, and cost–benefit analyses onextracorporeal membrane oxygenation use for refractory out-of-hospital cardiac arrest.Data sources: A structured systematic literature search of articles published pr

AI cancer detection models require calibration to attain the desired balance between cancer detection rate (CDR) and false positive rate. In this study, we simulate the impact of six types of mismatches between the calibration population and the clinical target population, by creating purposefully non-representative datasets to calibrate AI for clinical settings. Mismatching the acquisition year b

In this paper we show that OpenAI’s Large Language Model (LLM) GPT perform remarkably well when used for title and abstract eligibility screening of scientific articles and within a (systematic) literature review workflow. We evaluated GPT on screening data from a systematic review study on electric vehicle charging infrastructure demand with almost 12,000 records using the same eligibility criter

Global policies, legislation, and eco-friendly initiatives have induced the steel industry to integrate sustainable development approaches. Sustainability requires all phases from raw material sourcing to transportation to waste and carbon footprint elimination—yielding positive effects. This research employs a two-step approach in sustainability. The first phase entails conducting a systematic li

The delay between the origin of animals in the Neoproterozoic and their Cambrian diversification remains perplexing. Animal diversification mirrors an expansion in marine shelf area under a greenhouse climate, though the extent to which these environmental conditions directly influenced physiology and early organismal ecology remains unclear. Here, we use a biogeochemical model to quantify oxygen

Key questions for understanding hippocampal function in memory and navigation in humans are the type and source of visual information that reaches the human hippocampus. We measured bidirectional pairwise effective connectivity with functional magnetic resonance imaging between 360 cortical regions while 956 Human Connectome Project participants viewed scenes, faces, tools, or body parts. We devel

INTRODUCTION: We evaluated differences in p-tau levels between Alzheimer's disease (AD), a condition with brain-specific changes in p-tau, and amyotrophic lateral sclerosis (ALS), a condition associated with increases in peripheral p-tau levels. METHODS: Cerebrospinal fluid and plasma from 668 participants were analyzed using immunoassays specific for the low-molecular-weight (LMW) tau isoforms pr

Naturvetenskap, teknik, ingenjörsvetenskap och matematik, på engelska ofta grupperade under akronymen STEM, är traditionellt mansdominerade områden. Särskilt inom ingenjörsvetenskap och teknologi är kvinnor fortfarande kraftigt underrepresenterade. Bristen på kvinnor inom STEM innebär utmaningar i att möta arbetsmarknadens behov, för produktkvalitet på grund av brist på olika perspektiv i designprScience, technology, engineering and mathematics, often grouped under the acronym STEM, are traditionally male dominated fields. Especially in engineering and technology, women continue to be heavily underrepresented. The lack of women in STEM poses challenges for meeting the labor market demands, for product quality due to a lack of diverse perspectives in the design process, and for gender equal

How we teach is strongly influenced by the culture we teach in, especially what (we believe) our colleagues think is good and acceptable. Understanding the reluctance to changes in teaching practice, including fear of disapproval from colleagues and students, investigating and reappraising those fears, and starting to talk about alternative interpretations is a first step towards overcoming the in

Precise knowledge of the temperature during cutting processes is of high interest as the temperature of a cutting tool dictates the performance, and for the workpiece it controls the quality and integrity of the generated surface. For the first time, in this study, a novel technique has been developed utilizing phosphor thermometry for 2D surface temperature measurement of a cutting tool in metal

BACKGROUND: Low back pain (LBP) is a leading cause of work absence globally. Digital interventions have the potential to increase access to self-management support for individuals with persistent LBP.OBJECTIVE: This study aims to evaluate the feasibility, usability, and acceptability of a digital educational program (MyRelief) designed to support self-management strategies for people with persiste

Introduction: Most cervical cancer cases in Sweden are diagnosed among women who have failed to attend screening. The objective of this study was to analyze the effectiveness of offering vaginal HPV (human papillomavirus) self-samples to long-term non-attendees as a routine in this screening program, in which non-attendees had already been the targets of several interventions. Material and Methods

BACKGROUNDDistinguishing wide complex tachycardia (WCT) as ventricular tachycardia (VT) or supraventricular WCT (SWCT) is critical yet challenging. Manual ECG algorithms require substantial expertise and are inconsistently applied, and contemporary computerized ECG interpretation (CEI) systems often return only a generic “wide complex tachycardia” label. Novel machine learning–based ECG models (So

Future connected vehicles will require high-performance communication technologies for advanced cooperative driving applications such as maneuvering and cooperative perception. mmWave communications can meet the bandwidth requirements of such applications, but the typically harsh propagation conditions of vehicular environments hinder the broad adoption of mmWave devices on cars.
