Background: Quantitative SPECT in radionuclide-therapy is limited by partial-volume effects (PVEs). The implementation of regional voxels (r.v.), estimating mean activity concentrations in regions directly from projections, offers a promising alternative for the geometry-specification to reduce PVEs. Purpose: This study aims to demonstrate that activity-concentration estimation with r.v. is superi
We realize strongly confined quantum dots (QDs) in InAs nanowires (NWs) by combining epitaxial crystal-phase control with chemical wet etching. A strong axial confinement is first introduced by growing closely spaced wurtzite (WZ) tunnel barriers in NWs to enclose a zinc blende (ZB) QD. The NW cross-section is then reduced by isotropic etching to obtain very small QDs, with a maximum observed char
Monitoring atmospheric CO2 concentration changes across China is crucial for reducing carbon emissions and tackling global warming. Due to monitoring gap in satellite observations, this paper uses the Extremely Randomized Trees (ERT) model alongside OCO-2 satellite data and predictor variables to develop a 0.1° high-resolution monthly dataset of column-averaged dry air CO2 mole fraction (XCO2) in
OBJECTIVES: Early identification of treatment response in brain metastases remains clinically challenging. This study explores tensor-valued diffusion MRI (dMRI), specifically q-space trajectory imaging (QTI), as a novel source of early imaging biomarkers during stereotactic radiotherapy (SRT).METHODS: Twenty-six patients with brain metastases were enrolled; thirteen met quality and completeness c
Computational models play an increasingly vital role in scientific research by enabling the numerical simulation of complex processes. Such models are also fundamental in geosciences. For instance, they offer critical insights into the impacts of global change on the Earth system today and in the future. Beyond their value as research tools, models are also software products and should therefore a
Leafmines found on Genista berberidea Lange in northern Portugal led to the discovery of two new species: Phyllonorycter berberidella Nunes, Laštůvka & Laštůvka sp. nov. (Lepidoptera: Gracillariidae) and Achrysocharoides genistae Hansson sp. nov. (Hymenoptera: Eulophidae). The moth is described based on specimens reared from the host plant, and the wasp from individuals that emerged from the m
Internal crisis communication has long been undervalued compared to external communication, both in research and practice. Traditionally treated as a secondary, information‑driven activity, it is now gaining increased attention. Effective internal crisis communication is crucial not only for managing crises, but also for preventing secondary communication crises, supporting organizational learning
As some insect groups are declining at alarming rates, accurate and automated insect monitoring is needed to prioritize habitats for conservation. The dual-band entomological Scheimpflug lidar technique is a promising candidate method for real-time insect monitoring: it allows the detection of thousands of flying insects per day at high temporal and spatial resolutions. The signals contain a pleth
This Further engagement article takes up Blok and Jensen's recent call, made through a Dialogues in Sociology Forum, to ‘invent around’ the work of Bruno Latour to highlight his continued relevance and contribution to the practice of sociology. It is proposed that one way in which Latour might be usefully invented around is by bringing his work, particularly on matters of concern, into greater rel
How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur
BACKGROUND: Vacuum-assisted abdominal closure (VAC) is being increasingly used as an adjunctive procedure in the surgical treatment of secondary peritonitis. This study compared postoperative mortality and complication rates between VAC and primary abdominal closure (PAC).METHOD: This retrospective chart review included all patients diagnosed with secondary peritonitis who underwent laparotomy bet
AimsSocial participation is an important determinant of health-related behaviours and health. Communication disorders such as stuttering may be associated with participation. Research concerning the association between stuttering and social participation among older adults is scarce. Therefore, the aim of this population-based cross-sectional study was to investigate associations between self-perc
This chapter, based on over a decade of socio-legal research, details how legal inequality in Myanmar was built over decades, through both statutory weakening of personal status law and bureaucratic hurdles regarding everyday implementation and practice. The practice of personal status laws of minority communities is also impacted by restricted access to Myanmar citizenship following the introduct
World Values Survey (WVS) visar sedan decennier starka samband mellan religion, kultur och politik i olika länder. Dimensionerna traditionella vs sekulariserade värderingar respektive överlevnad vs självförverkligande (kollektivism vs individualism) är grundläggande för hur kulturella värderingar, ofta grundade i religion, interagerar med politiskt beteende och politiska beslut (Inglehart 1997, 20
Background Sex differences in valvular heart diseases have been examined but rarely using a nationwide, comprehensive approach.ObjectivesThe aim of this study was to analyze the risk of different types of valvular heart diseases among males and females in Sweden.MethodsThis was a nationwide Swedish study of all individuals (N = 9,984,758; 4,969,472 males and 5,015,286 females). Valvular heart dise
This article examines Friedrich Schelling’s understanding of the beginning of reality through the concept of contraction and its relation to his view of life as struggle. Drawing on his rejection of mechanistic accounts of life, the article shows how Schelling envisions all life – divine as well as finite – as arising through tension, polarity, and dynamic becoming. God is not a static principle b
Variational Mode Decomposition (VMD) is a powerful formalism for the time-scale analysis of vibration signals from rotating machinery. However, its performance is often compromised by complex parameter configuration, where subjective manual tuning leads to mode mixing or information loss. In this study, we present a physics-guided framework that generalizes VMD optimization across diverse operatin
The capacity of nutrient-limited forests to enhance carbon (C) sequestration under elevated CO2 (eCO2) remains a critical uncertainty in C cycle modeling. While existing evidence suggests that low phosphorus (P) bioavailability may constrain CO2 fertilization effects on plant growth, the extent to which this limitation modulates ecosystem responses to eCO2 in forests adapted to P-deficient soils r
