Gaia Data Release 3: The extragalactic content

The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes several million extragalactic objects down to a magnitude of G 21 mag. Due to the nature of the Gaia onboard-selection algorithms, these are mostly point-source-like objects. Using data prov

Sheltering in chaos : parents’ experiences when facing moral challenges in childhood cancer care

Childhood cancers are life-threatening diseases that affect the whole family. During the treatment moral situations might arise. Research on how parents perceive moral challenges in childhood cancer care is sparse. The aim was to explore parents’ main concern, and how they deal with their main concern, when facing moral challenges in childhood cancer care. Data collection included focus group inte

Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production

The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. One example is via the transition from conventional fossil fuel refineries to biorefineries, where renewable raw materials are utilised. Amongst these raw materials, the use of lignoce

Age and sex differences in cause-specific excess mortality and years of life lost associated with COVID-19 infection in the Swedish population

Background: Estimating excess mortality and years of life lost (YLL) attributed to coronavirus disease 19 (COVID-19) infection provides a comprehensive picture of the mortality burden on society. We aimed to estimate the impact of the COVID-19 pandemic on age- and sex-specific excess mortality and YLL in Sweden during the first 17 months of the pandemic. Methods: In this population-based observati

The evolutionary history of “suboptimal” migration routes

Migratoriness in birds is evolutionary labile, with many examples of increasing or decreasing migration distances on the timescale of modern ornithology. In contrast, shifts of migration to more nearby wintering grounds seem to be a slow process. We examine the history of how Palearctic migratory landbirds have expanded their wintering ranges to include both tropical Africa and Asia, a process tha

Psychiatry Nurses' Experiences of Patient-Initiated Brief Admission from Inpatient and Outpatient Perspectives : A Qualitative Exploratory Study

Patient-initiated brief admission (PIBA) allows patients to decide when admission to psychiatric care is necessary. This may prevent long-term hospitalisation and promote patient participation. Research on psychiatric nurses' experiences with PIBA is lacking, therefore 11 nurses were interviewed and data analysed using content analysis. Prominent categories were: improved personal development for

Prognostisk riskstratifiering vid pulmonell arteriell hypertension

The 2022 ESC/ERS pulmonary hypertension guidelines recommend multiparametric risk stratification at diagnosis and follow-up to guide treatment in pulmonary arterial hypertension (PAH). The goal is to maintain or achieve a low-risk status, corresponding to a 1-year mortality < 5%. Risk assessment is, however, underutilized in clinical practice, and applied only by 60% of clinicians. To overcome the

Microwave-Assisted Semisynthesis and Leishmanicidal Activity of Some Phenolic Constituents from Lichens

Leishmaniasis is considered one of the most untreated tropical diseases in the world. In this study, we investigated the in vitro leishmanicidal activity and cytotoxicity of various isolated lichen substances, including atranorin (1), usnic acid (2), gyrophoric acid (3), salazinic acid (4), galbinic acid (5), and parietin (6), and some semi-synthetic imine derivatives of usnic acid (7, 8, 9) and a

EMI classroom communication : A corpus-based approach

Examining English medium instruction (EMI) through a corpus-based approach, this volume offers a critical inquiry into the use of different linguistic and pedagogical strategies in the EMI classroom. It explores aspects of content lecturers' language use, pedagogy, and intercultural communicative competence by drawing on the findings obtained from EMI lecture corpus analysis and post-observation i

Emergence of Weyl fermions by ferrimagnetism in a noncentrosymmetric magnetic Weyl semimetal

Condensed matter physics has often provided a platform for investigating the interplay between particles and fields in cases that have not been observed in high-energy physics. Here, using angle-resolved photoemission spectroscopy, we provide an example of this by visualizing the electronic structure of a noncentrosymmetric magnetic Weyl semimetal candidate NdAlSi in both the paramagnetic and ferr

Observation of flow angle and flow magnitude fluctuations in Pb-Pb collisions at sNN =5.02 TeV at the CERN Large Hadron Collider

This Letter reports on the first measurements of transverse momentum dependent flow angle ψn and flow magnitude vn fluctuations determined using new four-particle correlators. The measurements are performed for various centralities in Pb-Pb collisions at a center-of-mass energy per nucleon pair of sNN = 5.02 TeV with ALICE at the CERN Large Hadron Collider. Both flow angle and flow magnitude fluct

A New Technique for Pelvic and Vaginal Reconstruction in Abdominoperineal Rectal Excision : Combination of Gluteus Maximus Flap and Fasciocutaneous Flap

Resection of advanced rectal cancer might result in significant tissue loss, including pelvic floor and parts of the vaginal wall. Pelvic floor reconstruction using a musculocutaneous flap offers optimized healing abilities and the possibility of vaginal reconstruction. In Skåne University Hospital, two different flap techniques are used to reconstruct the perineum: the vertical rectus abdominis m

Tumour origin, diagnostic accuracy and histopathological evaluation in patients with periampullary cancer : nationwide cohort study

Background: The prevalence of different periampullary cancers (pancreatic ductal adenocarcinoma, distal cholangiocarcinoma, ampullary cancer and duodenal cancer) is heterogeneous in the literature. During the 2010s, a standardized histopathological protocol for pancreatoduodenectomy specimens based on axial slicing was adopted in Sweden. The present study sought to provide information about periam

China 6 EGR gasoline vehicles without a GPF may struggle to meet the potential SPN10 limit

Particles larger than 10 nm from engine exhaust are gaining global concerns. In light of this, to investigate how EGR affects gasoline vehicle SPN10 (solid particles larger than 10 nm) emissions, seven gasoline vehicles (hybrid or conventional) were studied experimentally. The results revealed that EGR vehicles risk failing the current limit (6 * 1011 #/km) more than those without EGR if the cut-o

Comparing different techniques for obtaining molecular size distributions of glycogen

Glycogen is a hyperbranched glucose polymer, serving as a major energy reservoir in animals. Characterization of the size distributions of complex branched polysaccharides helps in the understanding of their structural and functional properties. This study compared the effectiveness of various techniques in analyzing glycogen size distributions, namely size-separation-based techniques (size exclus

Updating the Definition of Cancer

Most definitions of cancer broadly conform to the current NCI definition: "Cancer is a disease in which some of the body's cells grow uncontrollably and spread to other parts of the body." These definitions tend to describe what cancer "looks like" or "does" but do not describe what cancer "is" or "has become." While reflecting past insights, current definitions have not kept pace with the underst

The Black Swan problem : The role of capital, liquidity and operating flexibility

How firms cope with tail risk is an under-researched problem in the literature on corporate risk management. This paper presents stylized facts on the nature of revenue shocks based on 65 years worth of Compustat data. We define a Black Swan as an unexpected year-on-year drop in revenue between 30%–90%. The rate of Black Swans has increased markedly since the 1970's and there are more pronounced c

East Asian Anxieties: Child-centered Relatedness and Parents’ Care Work in Education in Singapore

The size and ‘quality’ of the population are issues of major concern in contemporary East Asia, as fertility rates are falling and competitiveness increasingly centers on ‘a fitting’ human capital. While Singapore is located in Southeast Asia geographically speaking, it is culturally linked to East Asia in terms of its heritage of Confucianism and the Chinese language.
