Considerable efforts have been recently devoted to the task of small-scale modeling of crystal plasticity at a reasonable computational cost. A fully detailed description of plastic flows incrystals is possible only by molecular dynamics (MD) approaches, which accurately representmicromechanisms of plastic response while relying minimally on phenomenology.

Introduction: Risk evaluation for preeclampsia in early pregnancy allows identification of women at high risk. Prediction models for preeclampsia often include circulating concentrations of placental growth factor (PlGF); however, the models are usually limited to a specific PlGF method of analysis. The aim of this study was to compare three different PlGF methods of analysis in a Swedish cohort t

In contrast to artificial systems, animals must forage for food. In biology, the availability of energy is typically both precarious and highly variable. Most importantly, the very structure of organisms is dependent on the continuous metabolism of nutrients into ATP, and its use in maintaining homeostasis. This means that energy is at the centre of all biological processes, including cognition. S

Multiple studies have examined the extent to which consumers’ hunger levels predict their food choices and preference patterns. These investigations often involve making binary choices between hedonic foods (e.g., ice cream) that primarily serve to provide sensory pleasure, and utilitarian foods (e.g., bread) that mainly fulfill functional purposes. However, most consumers entering a grocery store

We study steady axisymmetric water waves with general vorticity and swirl, subject to the influence of surface tension. This can be formulated as an elliptic free boundary problem in terms of Stokes' stream function. A change of variables allows us to overcome the generic coordinate-induced singularities and to cast the problem in the form “identity plus compact,” which is amenable to Rabinowitz's

The Storage Location Assignment Problem (SLAP) is of primary significance to warehouse operations sincethe cost of order-picking is strongly related to where and how far vehicles have to travel. Unfortunately, ageneralized model of the SLAP, including various warehouse layouts, order-picking methodologies andconstraints, poses a highly intractable problem. Proposed optimization methods for the SLA

Background and ObjectivesEEG is widely used for prediction of neurologic outcome after cardiac arrest. To better understand the relationship between EEG and neuronal injury, we explored the association between EEG and neurofilament light (NfL) as a marker of neuroaxonal injury, evaluated whether highly malignant EEG patterns are reflected by high NfL levels, and explored the association of EEG bac

Smart cities and 3D printing technologies are attracting unprecedented attention with signs that they will be key drivers of societal and economic change. Yet, the connection in how 3D printing can enhance smart cities remains understudied. To this end, this paper argues that 3D printing has widespread applications across higher education and smart city settings through the opening and democratizi

Cities have been wildly successful over recent years in positioning themselves at the center of the global conversation on climate change. For example, the Intergovernmental Panel on Climate Change (IPCC) recently convened the Cities & Climate Change Conference (CitiesIPCC) in Edmonton, Alberta. The conference — hosted by a city that once advertised itself as Canada’s oil capital — brought tog

Motivated by a need to characterize transient behaviors in large network systems in terms of relevant signal norms and worst-case input scenarios, we propose a novel approach based on existing theory for matrix pseudospectra. We extend pseudospectral theorems, pertaining to matrix exponentials, to an input-output setting, where matrix exponentials are pre- and post-multiplied by input and output m

This paper evaluates an electric generator manufactured of cobalt-iron laminations used for a wave energy application. The properties of the two cobalt-iron designs are compared with a reference machine, which employs conventional electric steel laminations. Operation trajectories and machine losses, as well as the annual energy production and the losses are obtained through finite element analysi

The COVID-19 accelerated shift towards hybrid workspaces places major pressure onworkplace communities and culture. This study explores the emergence of a collaborative academic workspace, which is still in the real estate development phase. The aim is to establish preconditions for community building, and the relationship between the community and the physical space. The study employs a qualitati

The Eurasian spruce bark beetle, Ips typographus, is a major pest, capable of killing spruce forests during large population outbreaks. Recorded dispersal distances of individual beetles are typically within hundreds of meters or a few kilometers. However, the connectivity between populations at larger distances and longer time spans and how this is affected by the habitat is less studied, despite

Decarbonizing society will require a shift toward renewable electricity production. However, the temporal configuration of renewables requires that demand adapt accordingly. Introducing intermittent electricity production will thus require end users to be more flexible in their use of electricity. Flexibility capital has been promoted as a concept for analyzing material preconditions in order to u

Opportunities and barriers for occupational engagement among residents in supported housing. Background: Research shows that people with psychiatric disabilities view supported housing (SH) as a possibility for social contact, but also as entailing a risk of deprived self-determination. There is, however, little research on the target group’s engagement in everyday occupations. Aim: To explore SH

The framework of Dynamical Movement Primitives (DMPs) has become a popular method for trajectory generation in robotics. Most robotic systems are subject to saturation and/or kinematic constraints on motion variables, but DMPs do not inherently encode constraints and this may lead to poor tracking performance. Temporal coupling (online temporal scaling) of DMPs represents a possible way for handli

In this paper, we present a system for extracting tabular information from loosely structured handwritten documents. The system consists of three parts, (i) a u-net like CNN-based method for text detection and segmentation, (ii) a new attention-based method for simultaneous text recognition and classification of word-parts, and (iii) a method for matching the word parts into a tabular structure fo
