We present a method for optimal control with respect to a linear cost function for positive linear systems with coupled input constraints. We show that the Bellman equation giving the optimal cost function and resulting sparse state feedback for these systems can be stated explicitly, with the solution given by a linear program. Our framework admits a range of network routing problems with underly
Background: Irritable bowel syndrome (IBS) is common with a global prevalence of 4%. Dietary regimes with a low content of fermentable oligo-, di-, and monosaccharides and polyol (FODMAP) or a starch- and sucrose-reduced diet (SSRD) have proven to be efficient. The aim of the present study was to describe the recruitment process for a randomized dietary trial with low FODMAP or SSRD for 4 weeks wi
For magnetic field orientation of nonstructures to become a viable method to create high performance multifunctional nanocomposites, it is of paramount importance to develop a method that is easy to implement and that can induce long-range uniform nanostructural alignment. To overcome this challenge, inspired by low field nuclear magnetic resonance (NMR) technology, a highly uniform, high field st
The optimization of expensive-to-evaluate black-box functions is prevalent in various scientific disciplines. Bayesian optimization is an automatic, general and sample-efficient method to solve these problems with minimal knowledge of the underlying function dynamics. However, the ability of Bayesian optimization to incorporate prior knowledge or beliefs about the function at hand in order to acce
This article discusses the potentials of a/r/tography aka artography against the background of life in an accelerating academia that is increasingly shallow and unfulfilling, and where quality is only indirectly measured using bibliometrics. We find Hartmut Rosa’s concept of resonance to be useful when discussing the values that get lost in such a system. We appreciate the arguments for a slower,
Both in the social and natural sciences, methodologies have been developed to deal with relatively stable conditions, where findings can be validated based on past experiences. At a time when both social and natural phenomena are rapidly changing, new approaches are urgently needed to produce knowledge for systemic change, inform high-stakes decisions, and enable sustainability transitions in the
Background: The affective profiles model, operationalized as the combination of individuals’ high/low positive/negative affective experience, is a well-established method for providing insights into adolescents’ affective functioning and self-regulation: self-fulfilling (high positive affect, low negative affect), high affective (high positive affect, high negative affect), low affective (low posi
Background: Conceptualizing affect as two separate signal sensitivity subsystems, defined as high/low positive affect and high/low negative affect, implies that (A) the study of affectivity needs the interaction between these two dimensions in a complex adaptive meta-system composed of combinations beyond the two-system approach and that (B) this meta-system is associated to individual differences
This study aimed to synthesize carbon dioxide, moisture, and heat emission load profiles in an overcrowded Swedish household. The study gathered realistic values for emissions from individuals and other household sources through an extensive literature review. It explored various aspects of daily routines, including showering, laundry, wet cleaning, dishwashing, cooking, and pets and plants. The s
Background: The teaching profession is considered as one of the most highly stressful professions. Indeed, teachers from many countries report high levels of stress and low levels of subjective well-being (e.g., low levels of positive affect and high levels of negative affect). In this context, a teachers’ affective profile might be an indication of their vulnerability for falling into counterprod
Background: Affectivity has been suggested as a complex adaptive meta-system composed of positive affect and negative affect, two independent but interrelated markers of well-being, that can be represented as four distinct affective profiles: self-fulfilling (high positive affect/low negative affect), high affective (high positive affect/high negative affect), low affective (low positive affect/lo
At the heart of this research are relational encounters between people and textile materials. As the title, Crafting Material Bodies, indicates, the research explores how human bodies are crafted by material bodies (costume) and vice versa. In the research textile materials and people are my co-creators and as co-creators they are invited to relate to, affect and become affected by other human bod
Background: Individuals’ perception of their work climate is expected to strongly influence personnel’s organizational commitment. However, the evidence about the association between organizational commitment and important outcomes, such as performance at work and turnover, is mixed. If this was not enough, little attention has been paid to how individual differences in basic personality (e.g., in
CoSAXS is a state-of-the-art SAXS/WAXS beamline exploiting the high brilliance of the MAX IV 3 GeV synchrotron. By coupling advances in sample environment control with fast X-ray detectors, millisecond time-resolved scattering methods can follow structural dynamics of proteins in solution. In the present work, four sample environments are discussed. A sample environment for combined SAXS with UV–v
Background: During the last years, the affective profiles model has been applied to study individual differences among Spanish children in psychological characteristics, such as optimism and pessimism. This research has replicated past studies from adult and adolescent Swedish populations by identifying four profiles using clustering methods on self-reports of children’s experience of positive (PA

Background: The affective profiles model has been used in several studies investigating individual differences in, for example, well-being and ill-being. The model categorizes individuals in four profiles based on the balance of high/low positive/negative affect: (1) self-fulfilling (high positive affect, low negative affect); (2) high affective (high positive affect, high negative affect); (3) lo
