Pupil contagion variation with gaze, arousal, and autistic traits

Pupillary contagion occurs when one's pupil size unconsciously adapts to the pupil size of an observed individual and is presumed to reflect the transfer of arousal. Importantly, when estimating pupil contagion, low level stimuli properties need to be controlled for, to ensure that observations of pupillary changes are due to internal change in arousal rather than the external differences between

Influence of autistic traits and communication role on eye contact behavior during face-to-face interaction

Eye contact is a central component in face-to-face interactions. It is important in structuring communicative exchanges and offers critical insights into others' interests and intentions. To better understand eye contact in face-to-face interactions, we applied a novel, non-intrusive deep-learning-based dual-camera system and investigated associations between eye contact and autistic traits as wel

Visuomotor tracking strategies in children : associations with neurodevelopmental symptoms

Children with neurodevelopmental disorders (NDDs) often display motor problems that may impact their daily lives. Studying specific motor characteristics related to spatiotemporal control may inform us about the mechanisms underlying their challenges. Fifty-eight children with varying neurodevelopmental symptoms load (median age: 5.6 years, range: 2.7-12.5 years) performed an interactive tablet-ba

Self-reported eye contact sensitivity and face processing in chromosome 22q11.2 deletion syndrome

INTRODUCTION: 22q11.2 deletion syndrome (22qDS) has been associated with varying levels of social impairments, and with atypical visual scanning of faces. The present study explored whether self-reported sensitivity to eye contact might be related to these phenomena.METHOD: Individuals with confirmed 22qDS were interviewed about their experience and possible discomfort with eye contact. In cases w

A novel end-to-end dual-camera system for eye gaze synchrony assessment in face-to-face interaction

Quantification of face-to-face interaction can provide highly relevant information in cognitive and psychological science research. Current commercial glint-dependent solutions suffer from several disadvantages and limitations when applied in face-to-face interaction, including data loss, parallax errors, the inconvenience and distracting effect of wearables, and/or the need for several cameras to

Paediatric Acute-onset Neuropsychiatric Syndrome (PANS) and intravenous immunoglobulin (IVIG) : comprehensive open-label trial in ten children

BACKGROUND: Treatment with intravenous immunoglobulin (IVIG) in children with Paediatric Acute-onset Neuropsychiatric Syndrome (PANS) has for many years been used on clinical indications, but the research evidence for its efficacy is insufficient.METHODS: Open-label prospective in-depth trial including ten children (median age 10.3 years) with PANS, who received IVIG treatment 2 g/kg monthly for t

A novel tablet-based motor coordination test performs on par with the Beery VMI subtest and offers superior temporal metrics : findings from children with pediatric acute-onset neuropsychiatric syndrome

Neuropsychiatric and neurodevelopmental disorders are often associated with coordination problems. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) constitutes a specific example of acute and complex symptomatology that includes difficulties with motor control. The present proof-of-concept study aimed at testing a new, bespoke tablet-based motor coordination test named SpaceSwipe, providing

Social and motor coordination: methods development and applications in ESSENCE

This thesis aimed to develop and apply methods for evaluating social and motor coordination, domains that often are challenged in individuals with neurodevelopmental/neuropsychiatric disorders (NDDs), also referred within Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCE). In Study I, we created a new tablet-based motor test that could accurately probe motor c

On PI-control in Capacity-Limited Networks

This paper concerns control of a class of systems where multiple dynamically stable agents share a nonlinear and bounded control-interconnection. The agents are subject to a disturbance which is too large to reject with the available control action, making it impossible to stabilize all agents in their desired states. In this nonlinear setting, we consider two different anti-windup equipped propor

Triple oxygen isotope reveals insolation-forced tropical moisture cycles

Tropical oceans are the main global water vapor and latent heat sources, but their responses to radiative forcing remain unclear. Here, we investigate oceanic moisture dynamics of the western tropical Pacific (WTP) over the past 210,000 years through an approach of planktonic foraminiferal triple oxygen isotope (Δ′17O). The Δ′17O record is dominated by the precession cycles (~23,000 years), with l

Particle impact in high-pressure homogenizer valves – A step towards understanding wear and cell breakup in food and beverage processing

In many liquid food processing applications using high-pressure homogenizers (HPHs), particles impact with the solid surfaces of the homogenization device. This may lead to costly wear. For some applications, impact is also postulated to control the desired cell disruption. This contribution uses computational fluid dynamics to study impact of particles on solid surfaces in HPHs, as a step towards

Drop breakup can occur inside the gap of a high-pressure homogenizer – New evidence from experimental breakup visualizations

High-pressure homogenizers are used extensively in food and beverage processing. For design and operation optimization, it is vital to understand where breakup takes place. Using an experimental high-speed camera setup on a scaled model, this contribution shows that breakup events can occur inside of the gap of a homogenizer valve. This contrasts with many previous studies which only observe break

Association between early airway intervention in the pre-hospital setting and outcomes in out of hospital cardiac arrest patients : A post-hoc analysis of the Target Temperature Management-2 (TTM2) trial

Introduction: Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients’ outcomes, including ventilator-free d

The role of performativity in comics as activism : Meaning-making in comic art by Amalia Alvarez and Sara Granér

Comic art has been described as having an ability to challenge taken for granted assumptions, illuminate cultural norms, and contest and give space for alternative imaginaries. Approaching comics as both art and activism, this chapter takes hold of the capacity in comic art to make visible and shape action in relation to social conventions and cultural norms. It does so by reading comics through a

Anisotropic coarse-grain Monte Carlo simulations of lysozyme, lactoferrin, and NISTmAb by precomputing atomistic models

We develop a multiscale coarse-grain model of the NIST Monoclonal Antibody Reference Material 8671 (NISTmAb) to enable systematic computational investigations of high-concentration physical instabilities such as phase separation, clustering, and aggregation. Our multiscale coarse-graining strategy captures atomic-resolution interactions with a computational approach that is orders of magnitude mor
