Design of Perfectly Conducting Objects That Are Invisible to an Incident Plane Wave

This work concerns the design of perfectly conducting objects that are invisible to an incident transverse magnetic plane wave. The object in question is a finite planar waveguide with a finite periodic array of barriers. By optimizing this array, the amplitude of the scattered field is reduced to less than 10-9 times the amplitude of the incident plane wave everywhere outside the waveguide. To ac

Holding time has limited impact on constitutive innate immune function in a long-lived Antarctic seabird, the Adélie penguin : implications for field studies

There is great interest in measuring immune function in wild animals. Yet, field conditions often have methodological challenges related to handling stress, which can alter physiology. Despite general consensus that immune function is influenced by handling stress, previous studies have provided equivocal results. Furthermore, few studies have focused on long-lived species, which may have differen

Increased Multiplexing Gain with Reconfigurable Surfaces : Simultaneous Channel Orthogonalization and Information Embedding

Reconfigurable surface (RS) has been shown to be an effective solution for improving wireless communication links in general multi-user multiple-input multiple-output (MU-MIMO) setting. Current research efforts have been largely directed towards the study of reconfigurable intelligent surface (RIS), which corresponds to an RS made of passive reconfigurable elements with only phase shifting capabil

Structural and chemical transformations of CuZn alloy nanoparticles under reactive redox atmospheres : An in situ TEM study

Alloying metals to form intermetallics has been proven effective in tuning the chemical properties of metal-based catalysts. However, intermetallic alloys can undergo structural and chemical transformations under reactive conditions, leading to changes in their catalytic function. Elucidating and understanding these transformations are crucial for establishing relevant structure-performance relati

How the Brain Constructs and Maintains Coherent Episodic Memories through Eye Movements

The process of constructing, maintaining, and reconstructing episodic memories is closely linked to the temporal dynamics of visual exploration through sequences of eye movements (Johansson et al., 2022; Nikolaev et al., 2023). However, the neural mechanisms that mediate relational memory across eye movements are not yet fully understood. This study presented participants with a series of visuospa

Dressed for the occasion! Ecotypic divergence, phenotypic plasticity and taxonomic value of capitulum characters of Scorzoneroides autumnalis (Asteraceae)

Scorzoneroides autumnalis is a highly polymorphic perennial with several described infraspecific taxa, largely differing in involucre colour and indumentum intensity. Here, we examine the role of ecotypic divergence and phenotypic plasticity in shaping large-scale geographical variation in these characters. We collected phenotypic data from herbarium specimens and garden-grown plants of S. autumna

Waste Viscose for Optically pure Lactic acid Production

Recycling of textile fibers is a mandatory step in the life-cycle of fabrics to avoid incineration or landfilling. After fiber-to-fiber recycling, cellulose fiber saccharification opens the door to the production of biochemical building blocks through microbial fermentation. This study documents for the first time the production of optically pure D-lactic acid (D-LA), one of the precursors of poly

Cross-modal Imaging in Lung Research: From µCT dosimetry to synchrotron phase contrast microtomography biomechanical insights in preclinical lung injury models

Lung diseases continue to present a large burden to public health, especially in industrialized countries. For abetter understanding of the underlying patho-mechanisms in lung related diseases as well as for testing theefficacy of novel therapies, preclinical studies in animal models are indispensable. The significance of preclinical X-ray based micro-computed tomography (µCT) research lies in its

Individual and psychosocial study environment characteristics associated with exposure to sexual harassment at a large public university in Sweden

Background and Objective: Universities can be understood as work-like environments for students. Limited research has examined this study environment from a Demand-Control-Support perspective with regards to sexual harassment. Understanding this environment is key to designing preventative measures. This study therefore aimed to examine the association between individual and psychosocial study env

Predicting Attitudes Towards the Exchange of Sexual Services for Payment : Variance in Gender Gaps Across the Nordic Countries

Introduction: This article explores how individual-level attitudes towards the exchange of sexual services for payment differ between the Nordic countries. The sparse existing research points to gender and general attitudes towards sexual behavior as powerful predictors of attitudes towards the exchange of sex for payment. However, there are no previous research agendas that attempt to explain var

Transformative public procurement for innovation : ordinary, dynamic and functional capabilities

Public Procurement for Innovation (PPI) requires multiple roles from the public administration according to the problem-solution space, delineated by the level of consensus around the definition of the needs of the contracting authority and the potential solutions to address them. Each role involves a distinct mix of capabilities, which we categorize as ordinary (i.e. doing things right), dynamic

Population scale proteomics enables adaptive digital twin modelling in sepsis

Sepsis is one of the leading causes of mortality in the world. Currently, the heterogeneity of sepsis makes it challenging to determine the molecular mechanisms that define the syndrome. Here, we leverage population scale proteomics to analyze a well-defined cohort of 1364 blood samples taken at time-of-admission to the emergency department from patients suspected of sepsis. We identified panels o

Barking up the wrong tree? : A guide to forest owner typology methods

Creating typologies of forest owners is a common approach for analyzing and understanding heterogeneity in responses to forest policies and management practice uptake. While many forest owner typologies have been developed, only a few quantitative methods dominate the field with little information on how methodological choice affects outcomes. In this study we compare five methods for quantitative

TRPA5 encodes a thermosensitive ankyrin ion channel receptor in a triatomine insect

As ectotherms, insects need heat-sensitive receptors to monitor environmental temperatures and facilitate thermoregulation. We show that TRPA5, a class of ankyrin transient receptor potential (TRP) channels absent in dipteran genomes, may function as insect heat receptors. In the triatomine bug Rhodnius prolixus (order: Hemiptera), a vector of Chagas disease, the channel RpTRPA5B displays a u

Neocortical interpretation of haptic and visual events across brain states: Electrophysiological investigations in sensory information processing

This thesis delves into the complex architecture of dynamic sensory information processing in the neocortex. Specifically, it asks how primary sensory cortical regions are influenced by local and widespread cortical state changes. Central to this question is the exploration of two historically opposing information processing frameworks emphasizing a local and global information processing principl

Socio-demographic inequalities influence differences in the chemical exposome among Swedish adolescents

Relatively little is known about the relationship between socio-demographic factors and the chemical exposome in adolescent populations. This knowledge gap hampers global efforts to meet certain UN sustainability goals. The present work addresses this problem in Swedish adolescents by discerning patterns within the chemical exposome and identify demographic groups susceptible to heightened exposur

The Unpredictable Ulnar Nerve—Ulnar Nerve Entrapment from Anatomical, Pathophysiological, and Biopsychosocial Aspects

Peripheral nerves consist of delicate structures, including a rich microvascular system, that protect and nourish axons and associated Schwann cells. Nerves are sensitive to internal and external trauma, such as compression and stretching. Ulnar nerve entrapment, the second most prevalent nerve entrapment disorder after carpal tunnel syndrome, appears frequently at the elbow. Although often idiopa

Screening Greenland in Borgen - Power & Glory : The on- and off-screen contestedness of Arctic landscapes and locations

This article shows how the Arctic landscapes in the Danish political drama series Borgen: Power & Glory demonstrate Greenland as a contested land in distinct ways: culturally due to the postcolonial tension between Denmark and Greenland; politically due to the conflicted interests from Denmark and other nations for the country’s natural resources; environmentally due to the looming transformat
