We review and extend the list of stability and convergence properties satisfied by Runge-Kutta (RK) methods that are associated with Summation-By-Parts (SBP) operators, herein called RK-SBP methods. The analysis covers classical, generalized as well as upwind SBP operators. Previous work on the topic has relied predominantly on energy estimates. In contrast, we derive all results using a purely al

In the context of range-independent solid media, we propose a well-conditioned dynamic stiffness matrix for an elastic layer sitting over an elastic half-space. This formulation overcomes the well-known problem of numerical ill-conditioning when solving the system of equations for deep-layered strata. The methodology involves the exact solutions of transformed ordinary differential equations in th

This paper tests how gender stereotypes may result in biased student evaluations of teaching (SET). We thereby contribute to an ongoing discussion about the validity and use of SET in academia. According to social psychological theory, gender biases in SET may occur because of a lack of fit between gender stereotypes, and the professional roles individuals engage in. A lack of fit often leads to m

The chapter analyzes the results of an online survey conducted in Ukraine, Serbia, Georgia, and Montenegro in 2022. The chapter uses the convenience sampling technique to explore reasons and test the validity of the scales. We explore online practices and perceptions of online rituals to examine further whether online practices correlate with vaccination. The chapter shows that urban respondents f

Sepsis manifests due to the host's dysregulated immune response to infection. High-dose ascorbic acid (AA) has emerged as a potential treatment of sepsis, yet little is known regarding how AA influences the immune system in sepsis, such as monocytes. The objective of this study is to investigate the effects of high-dose AA on monocyte polarization and cytokine production in vitro. Monocytes isolat

As video and computer games get increasingly more advanced, the immersive experience for the player of these games also follows this trajectory. In these games, one aspect that has been explored to the greatest extent is that of choice and player agency. Often, these choices and acts are of a moral character, whether it be choosing what to do on an ambiguously formulated questline with multiple br

Background: Disengagement from outdoor recreation may diminish the positive benefits on health and well-beingin old age. The purpose of this study is to present a contextual, theoretical, and empirical rationale for anintervention, aiming to promote continued engagement in outdoor recreation for older adults in a Swedishcontext.Methods: The paper includes a contextualization of outdoor recreation

One of the most recent definitions for a sandwich panel is the one used in the European product standard EN 14509. This product standard defines a sandwich panel as a building product consisting of two metal faces positioned on either side of a core that is a rigid thermally insulating material, which is firmly bonded to both faces so that the three components act compositely when under load. In m

In Schacter (2022), the author outlines the considerable progress that has been made in characterizing the impact of five (of the seven) sins of memory; specifically, transience, absentmindedness, misattribution, suggestibility, and persistence. As in his influential book, The Seven Sins of Memory: How the Mind Forgets and Remembers (Schacter, 2001, 2021), Schacter notes that this last sin of pers

Objective: In this study, we propose a novel framework that utilizes deep learning and attention mechanisms to predict the radiographic progression of patellofemoral osteoarthritis (PFOA) over a period of seven years. Design: This study included subjects (1832 subjects, 3276 knees) from the baseline of the Multicenter Osteoarthritis Study (MOST). Patellofemoral joint regions-of interest were ident

Preventing and mitigating damage to the surroundings arising from process safety incidents is an important aspect of process safety. Risk-informed or risk-based decision-making are cornerstones in most countries’ regulatory regimes for land-use planning. However, the design and implementation of the regulations vary significantly - from countries that have chosen a highly standardized set of rules

The article discusses strategies adopted in Jonas Poher Rasmussen’s feature-length animated documentary Flee (2021) for crossing the cultural andemotional distance between audiences and the refugee protagonist Amin. Focusis on a central scene in which a group of Afghans sailing across the Baltic Seain the early 1990s encounters a cruise ship from Norway, the crew of whichreports the refugees to th
