Accurate and experimentally validated transition data for Si I and Si II

Aims. The aim of this study is to provide radiative data for neutral and singly ionised silicon, in particular for the first experimental oscillator strengths for near-infrared Si I lines. In addition, we aim to perform atomic structure calculations both for neutral and singly ionised silicon while including lines from highly excited levels. Methods. We performed large-scale atomic structure calcu

Optimising External Beam Radiotherapy for Prostate Cancer. Advances in Treatment Planning

BackgroundRadiotherapy (RT) is an effective treatment option for prostate cancer (PCa). The evolution of new treatment planning techniques, advanced imaging and accelerator design has enabled precise treatment delivery. Volumetric modulated arc therapy (VMAT) optimisation techniques achieve sharp dose gradients between the target and organs at risk (OAR) and have become the standard of care for PC

Illusion of Control : Psychological Characteristics as Moderators in Financial Decision Making

Financial decision making requires a sound handling of chance events. However, various studies have suggested that people are prone to illusion of control, i.e., the belief that prospects of a chancy event are better if they are involved in the randomisation process. This paper reports results from an experiment ((Formula presented.)) suggesting that psychological characteristics moderate risk-tak

The Advancement in Spring Vegetation Phenology in the Northern Hemisphere Will Reverse After 2060 Under Future Moderate Warming Scenarios

Global warming has largely advanced spring vegetation phenology, which has subsequently affected terrestrial carbon and water cycles. However, further shifts in vegetation phenology under future climate change remain unclear. We estimated the start of the growing season (SOS) by applying multiple extraction methods based on the NDVI3g data set, and then parameterized and evaluated 11 spring vegeta

QM/MM study of the catalytic reaction of aphid myrosinase

Brevicoryne brassicae, an aphid species, exclusively consumes plants from the Brassicaceae family and employs a sophisticated defense mechanism involving a myrosinase enzyme that breaks down glucosinolates obtained from its host plants. In this work, we employed combined quantum mechanical and molecular mechanical (QM/MM) calculations and molecular dynamics (MD) simulations to study the catalytic

Decoding the rhizodeposit-derived carbon's journey into soil organic matter

Net rhizodeposition corresponds to the portion of living root carbon (C) that remains in the soil after microbial processing and partial decomposition. Although it is assumed that this C input exerts an important role in the formation of soil organic matter (SOM), its contribution to distinct SOM pools is still not fully understood. In this study, we aimed to (i) quantify the retention of net rhiz

Pericyte Microvesicles as Plasma Biomarkers Reflecting Brain Microvascular Signaling in Patients with Acute Ischemic Stroke

BACKGROUND: Blood-based biomarkers have the potential to reflect cerebrovascular signaling after microvascular injury; yet, the detection of cell-specific signaling has proven challenging. Microvesicles retain parental cell surface antigens allowing detection of cell-specific signaling encoded in their cargo. In ischemic stroke, the progression of pathology involves changes in microvascular signal

Bismuth-oxide nanoparticles: study in a beam and as deposited

Bi2O3 is a promising material for solid-oxide fuel cells (SOFC) due to the high ionic conductivity of some phases. The largest value is reached for its δ-phase, but it is normally stable at temperatures too high for SOFC operation, while nanostructured oxide is believed to have more suitable stabilization temperature. However, to manufacture such a material with a controlled chemical composition i

Assessment of a hand-held CZT-based gamma camera for pre-clinical imaging of 177Lu

A small CdZnTe-based hand-held gamma-camera has been acquired, intended to be used for preclinical imaging. The camera produces images of size 4 cm x 4 cm with an image-matrix of 16 x 16 pixels and can be equipped with a low-energy high-sensitivity (LEHS) or a high-resolution (LEHR) parallel-hole collimator. Pre-clinical imaging involves scales smaller than what the camera is typically used for, a

Why does urban Artificial Intelligence (AI) matter for urban studies? : developing research directions in urban AI research

New digital technologies and systems are being extensively applied in urban contexts. These technologies and systems include algorithms, robotics, drones, Autonomous Vehicles (AVs) and autonomous systems that can collectively be labelled as Artificial Intelligence (AI). Critical debates have recognized that these various forms of AI do not merely layer onto existing urban infrastructures, forms of

Omställning till elbussar : Lärdomar, erfarenheter och rekommendationer

På senare år har elektrifiering av stadsbussar i kollektivtrafiken växlat upp i tempo och idag finns flera exempel på hur man har hanterat omställningen i svensk kollektivtrafik. I projektet e(+)bus har vi jobbat med fallstudier i Sverige (Stockholm, Göteborg, Malmö, Jönköping, Ystad, Piteå). Vi har även gjort en internationell utblick till Norge (Oslo och Trondheim) samt Nederländerna (Eindhoven)

Trafiksäkerhetsgranskning : Genomgång av några länders manualer/riktlinjer

Fyra manualer/riktlinjer har gåtts genom enligt internationella bästa praktik kriterier. Dessa fyra manualer/riktlinjer valdes då trafiksäkerhetsgranskning som en systematisk procedur startade i England och dess grundläggande principer förfinades i Australien. Det är också av intresse hur Sveriges grannländer, Danmark och Norge har utvecklat sina egna nationella manualer.

Trafiksäkerhetsgranskning - Riktlinjer

Baserat på genomgång av internationellt etablerade bästa praktik riktlinjer och fyra länders (Australien England, Danmark och Norge) manualer/riktlinjer har riktlinjer för trafiksäkerhetsgranskning i Sverige utarbetats.

Proving gender and sexuality in the (homo)nationalist Greek asylum system : Credibility, sexual citizenship and the ‘bogus’ sexual other

The aim of this article is to analyse and critique Greek authorities’ expectations for a ‘credible’ account in queer asylum claims. As some of the caseworkers’ accounts portray, through 16 semi-structured interviews, in order to be deemed ‘credibly queer’ applicants are expected to have passed through a painful, discursively narratable process of self-realization and have suffered enough in their

A bowhead whale vertebra embedded in marine limit beach sediment on Barentsøya, Svalbard

A cross-valley beach terrace in Iladalen in the south-eastern corner of Barentsøya (Svalbard) is interpreted as built by long-shore sediment transport and deposition, with its maximum height at 88 m a.s.l., marking the marine limit (ML) at deglaciation. A whale vertebra (most probably from a bowhead whale, Balaena mysticetus) was found embedded in the upper part of the littoral sediments at a hei

The open abdomen in trauma, acute care, and vascular and endovascular surgery : comprehensive, expert, narrative review

Background: The open abdomen is an innovation that greatly improved surgical understanding of damage control, temporary abdominal closure, staged abdominal reconstruction, viscera and enteric fistula care, and abdominal wall reconstruction. This article provides an evidence-informed, expert, comprehensive narrative review of the open abdomen in trauma, acute care, and vascular and endovascular sur

Cardiovascular events, mortality, early retirement and costs in >50 000 persons with chronic heart failure in Sweden

Aims: We aimed to examine cardiovascular events (stroke and myocardial infarction [MI]), mortality, early retirement and economic costs over 5 years in people with chronic heart failure (CHF) and matched controls in Sweden. Methods and results: Individuals (aged ≥16 years) living in Sweden on 1 January 2012 were identified in an existing database. Individuals with CHF were propensity score matched

Computed Tomography-Based Quantitative Texture Analysis and Gut Microbial Community Signatures Predict Survival in Non-Small Cell Lung Cancer

This study aims to combine computed tomography (CT)-based texture analysis (QTA) and a microbiome-based biomarker signature to predict the overall survival (OS) of immune checkpoint inhibitor (ICI)-treated non-small cell lung cancer (NSCLC) patients by analyzing their CT scans (n = 129) and fecal microbiome (n = 58). One hundred and five continuous CT parameters were obtained, where principal comp
