40 Hz invisible spectral flicker and its potential use in Alzheimer's light therapy treatment

Alzheimer's disease (AD) not only takes an emotional toll on the individual with the disease, their families, relatives, and caretakers, it also has immense socioeconomic consequences on the health care system and society. Moreover, the socioeconomic consequences are expected to increase significantly, thus reducing the social and economic cost of AD is of high importance. Recently, exposure to 40

Gender and willingness to lead: Does the gender composition of teams matter?

We explore how team gender composition affects willingness to lead by randomly assigning participants in an experiment to male- or female-majority teams. Irrespective of team gender composition, men are substantially more willing than women to lead their team. The pooled sample, and women separately, are more willing to lead female- than male-majority teams. An analysis of mechanisms reveals that

Assessing the accuracy of a deep learning method to risk stratify indeterminate pulmonary nodules

Rationale: The management of indeterminate pulmonary nodules (IPNs) remains challenging, resulting in invasive procedures and delays in diagnosis and treatment. Strategies to decrease the rate of unnecessary invasive procedures and optimize surveillance regimens are needed. Objectives: To develop and validate a deep learning method to improve the management of IPNs. Methods:ALung Cancer Prediction

Television Adaptations of Jane Austen’s Emma, 1972–2009

The aim of this paper was to analyse how three different television adaptations of Jane Austen’s Emma(1815) avail themselves of the medium of television to narrate the story. The productions analysed are John Glenister’s BBC series from 1972, dramatised by Denis Constanduros; Diarmuid Lawrence’s ITV film from 1996, dramatised by Andrew Davies; and Jim O’Hanlon’s BBC series from 2009, dramatised by

Designing high efficient solar powered lighting systems

Some major challenges in the development of L2L products is the lack of efficient converter electronics, modelling tools for dimensioning and furthermore, characterization facilities to support the successful development of the products. We report the development of 2 Three-Port-Converters respectively for 1-10Wp and 10-50 Wp with a peak efficiency of 97% at 1.8 W of PV power for the 10 Wp version

Intraabdominal and retroperitoneal soft-tissue sarcomas - Surgical treatment and outcomes

BACKGROUND: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.METHODS: A retrospective review of consecutive patients (n = 107) with IaRS treated at single center from 2

Om Kändisjournalistik

Avhandlingen närmar sig frågan om hur journalistiska praktiker underlättar konstruktionen av kändisstatus. Teoretiskt uppfattas kändisskap som en särskilt flytande form av social status baserat på medierad uppmärksamhet och engagemang. Journalistik studeras som en invitation att dela upplevelser, organiserade utifrån narrativa strukturer. De empiriska fallen som studeras i avhandlingen är två mångThe thesis approaches the research question of how journalistic practices facilitate the construction of celebrity status. Theoretically, celebrity is conceptualised as a particularly fluid form of social status based on mediatized attention and engagement. Journalism is studied as an invitation to shareexperiences, organised through media logics and narrative structures. The empirical cases studi

In-situ quantification of spatiotemporally resolved particle concentration in iron powder combustion using holographic imaging

In-situ quantification of particle concentration during the combustion of solid fuel powders is of importance for analyzing their combustion behaviors. Digital holography (DH) is applied here for studying iron powder combustion at high concentration. The performance of DH as a function of particle concentration is thoroughly studied with synthetic holograms. The detection efficiency is found to be

The structure of an immunodominant loop on foot and mouth disease virus, serotype O1, determined under reducing conditions

Residues 136-159 of VPI of foot and mouth disease virus (FMDV) comprise the G-H loop of the protein and form a prominent feature on the surface of virus particles. This sequence contains an immunodominant neutralizing epitope, which can be mimicked with synthetic peptides, and includes an Arg, Gly, Asp motif which has been implicated in the binding of the virus to cellular receptors. Crystallograp

Envisioning sustainable carbon sequestration in Swedish farmland

Negative trends of climate change and biodiversity loss are closely linked with farming practices, and it is therefore essential to re-think how agricultural systems can sequester more carbon, and simultaneously create vital ecosystems. The overall aim of this research is to imagine Swedish farms as carbon sinks rather than sources, and how to re-design the current farm- and food system to also ad

Experience Sampling Method in a Qualitative Study of Tourists' Smartphone Use

This chapter explores the use of Experience Sampling Method (ESM) in a qualitative research design, departing from reflections on ontological and epistemological aspects of the tourist experience. It suggests that the tourist experience can be studied in its ordinary moments and proposes the use of ESM to capture such experience of “everydayness”. The chapter illustrates how the method can be used

Hybrid peace mediation in the age of pandemics

The dawn of the COVID-19 pandemic in 2020 brought on an acceleration of the transition to virtual spaces in international diplomacy. Studying the virtualization of peace mediation, we describe the new conditions of hybrid peace mediation and show both advantages and challenges in comparison to traditional diplomatic face-to-face meetings. We show how virtual meetings have advantages, such as poten

Exploring “Planned Serendipity” and On-site Information Behavior on Smartphones

The paper explores tourists’ smartphone-related information behavior on site in light of the concept of “planned serendipity”. The ability to gatherinformation at anytime and anywhere can deeply influence tourists’ behavior,their information needs and the outcomes of their travel plans. In this study, theconcept of planned serendipity is used to suggest that the outcome of travelinformation behavi

Tourist information behaviour on site: smartphones and planned serendipity

Smartphones have become one of the main tools for travel information search, especially on site, during the trip. The use of mobile technologies and ubiquitous internet connectivity do not only allow tourists to access information anywhere, at any time, but have deep impacts on tourists’ behaviours and on their whole tourist experience.The study suggests an interpretation of tourists’ information

A nucleotide-sensing oligomerization mechanism that controls NrdR-dependent transcription of ribonucleotide reductases

Ribonucleotide reductase (RNR) is an essential enzyme that catalyzes the synthesis of DNA building blocks in virtually all living cells. NrdR, an RNR-specific repressor, controls the transcription of RNR genes and, often, its own, in most bacteria and some archaea. NrdR senses the concentration of nucleotides through its ATP-cone, an evolutionarily mobile domain that also regulates the enzymatic a
