Charles Darwin (1809–1882) är främst känd för sin evolutionsteori– om arters utveckling genom naturligt urval. Hans övriga arbetenär mindre kända. Mycket handlade om växter – om mekanismer för pollinering, blombiologi, rörelser och förmågan att ta upp näring från andra organismer – sådant som intresserat honom sedan studietiden i Cambridge. Med tiden kom han att publicera ett flertal böcker och en

PurposeThis study aimed to elucidate whether gadolinium contrast in clinically relevant doses can be used with photon-counting computed tomography (PCCT) as an alternative contrast agent in clinical applications.Material/methodsA CTDI phantom with 3D printed rods filled with different concentrations of gadolinium and iodine contrast was scanned in a PCCT and an energy-integrated computed tomograph

Materials with heterogeneous microstructures architected across several scales are becoming increasingly popular in structural applications due to unique strength–ductility balance. One of the most popular 3D-architected structure designs is harmonic structure (HS) where soft coarse-grain (CG) islands are embedded in a hard continuous 3D skeleton of ultrafine grains (UFGs). In this work, a series

Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. Elevated temperatures can accelerate microbial activity in soil, potentially resulting in an increased rate of soil or

OBJECTIVE:Recent advances in AI-based Large Language Models (LLM) can transform individuals’ descriptions of emotional health into numeric representations that predict rating scales with an accuracy approaching theoretical upper limits. This advancement enables examing various open-ended response formats. We develop and evaluate formats ranging from closed to more open: 1) selecting descriptive wo

Lipid metabolism dysregulation is a critical factor contributing to obesity. To counteract obesity-associated disorders, bariatric surgery is implemented as a very effective method. However, surgery such as Roux-en-Y gastric bypass (RYGB) is irreversible, resulting in life-long changes to the digestive tract. The aim of the present study was to elucidate changes in the fecal microbiota before and

Background: By being highly involved in the tumor evolution and disease progression of small cell lung cancer (SCLC), Myc family members (C-Myc, L-Myc, and N-Myc) might represent promising targetable molecules. Our aim was to investigate the expression pattern and prognostic relevance of these oncogenic proteins in an international cohort of surgically resected SCLC tumors. Methods: Clinicopatholo

Axially heterostructured nanowires (NWs) constitute a promising platform for advanced electronic and optoelectronic nanodevices. The presence of different materials in these NWs introduces a mismatch resulting in complex strain distributions susceptible of changing the band gap and carrier mobility. The growth of these NWs presents challenges related to the reservoir effect in the catalysts drople

Background: Quantitative cardiovascular magnetic resonance (CMR) first pass perfusion maps are conventionally acquired with 3 short-axis (SAX) views (basal, mid, and apical) in every heartbeat (3SAX/1RR). Thus, a significant part of the left ventricle (LV) myocardium, including the apex, is not covered. The aims of this study were 1) to investigate if perfusion maps acquired with 3 short-axis view

Language development is a long-term process. Individual-level longitudinal case studies have been foundational to SLA. However, methodologies that can support person-focused and process-oriented research lack consolidation. Qualitative longitudinal (QL) research (Neale, 2021a, 2021b) is a methodology that facilitates exploration of the influences of time over time. It provides a temporal architect

Sustaining yields for smallholder perennial agriculture under a rapidly changing climate regime may require consideration of landscape features and on-farm management decisions in tandem. Optimising landscape and management may not be possible for maximising yields in any one year but maintaining heterogeneous landscapes could be an important climate adaptation strategy. In this study, we observed
