Background: Analysis of how digital breast tomosynthesis (DBT) screening affects consecutive screening performance is important to estimate its future value in screening. Purpose: To evaluate whether DBT contributes to early detection of breast cancer by assessing cancer detection rates (CDRs), including the fraction of invasive cancers and cancer subtypes in consecutive routine digital mammograph
Quantum memories for quantum communication need to be able to store photons for an extended time and then to release them on demand. This can be achieved in atomic frequency comb ensemble-based quantum memories by control pulses that transfer the excitation to and from long-lived spin states. However, such pulses can give rise to coherent and incoherent noise due to their interaction with the memo
Understanding the mechanisms governing interfacial charge transfer in photoactive layer is crucial for optimizing photogenerated charge separation efficiency. In this study, the interfacial charge transfer process is regulated by applying external electric field (Fext) and ternary hydrogen bonding strategies. We observe significant changes in the excited state properties and charge transfer parame
In organic solar cells (OSCs), comprehending the charge transfer mechanism at D/A interfaces is crucial for photoinduced charge generation and enhancing power conversion efficiency (PCE). The charge transfer mechanism and photovoltaic performance of the parallel stacking interface configuration of the PTQ10 polymer donor and T2EH non-fullerene acceptor (NFA) are systematically studied at the micro
In this work, a specially designed experimental setup is employed to study the ignition and combustion of single aluminum droplets in hot steam-dominated flows. The transient burning behaviors of Al droplets of different sizes are characterized by simultaneously visualizing the flame incandescence and droplet shadowgraphs with two high-speed cameras at high magnification. The combustion process ca
Gastric cancer represents a serious health problem worldwide, with insufficient molecular biomarkers and therapeutic options. Consequently, several efforts have been directed towards finding specific disease markers in order to develop new therapies capable of defeating gastric cancer. Attention has been pointed to cancer stem cells (CSCs) as they are primarily responsible for tumor initiation and
To design an artificial protein-based molecular motor that can autonomously step along a track is a key challenge of protein design and synthetic biology. We lay out a roadmap for how to achieve this aim, based on a modular approach that combines the use of natural, non-motor proteins with de novo design. We define what can be considered to constitute a successful artificial protein motor, identif
Fire retardants are extensively used to reduce the flammability (combustibility) of wood–based construction materials in an effort to improve fire safety of buildings. However, little is known of the composition and potential risks to human health of smoke emissions produced from combustion of fire retardant treated wood. To help understand the risk to human health, fire smoke emissions produced f
Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu
Established ecological theory has focused on unitary organisms, and thus its concepts have matured into a form that often hinders rather than facilitates the ecological study of modular organisms. Here, we use the example of filamentous fungi to develop concepts that enable integration of non-unitary (modular) organisms into the established community ecology theory, with particular focus on its sp
Background: Tissue factor (TF), encoded by the F3 gene, is the main initiator of blood coagulation. The molecular epidemiology of the F3 gene and the relation to venous thromboembolism (VTE) remains to be determined. Objectives: The aim was to determine the molecular epidemiology and the importance of F3 variants for incident VTE by analysis of the population-based MDC study (Malmö Diet and Cancer
Introduction: The adverse health effects of sugar-sweetened beverage intake are well-established, but the implications of overall added sugar intake remain unclear. We investigated the associations between intake of added sugar and various sugar-sweetened foods and beverages and risk of 7 cardiovascular diseases in 69,705 participants aged 45–83 years (47.2% female) from the Swedish Mammography co
Soil aggregation is a dynamic process influenced by physical, chemical and biological factors; however, their individual and combined effect on the formation and turnover of aggregates is not well understood. The aim of this study was to examine incorporation of fresh litter inputs of different physicochemical properties including their carbon-to-nitrogen (C/N) ratio – maize (C/N = 12) and straw (
In clinical practice, the glomerular filtration rate (GFR), a measurement of kidney functioning, is normally calculated using equations, such as the European Kidney Function Consortium (EKFC) equation. Despite being the most general equation, EKFC, just like previously proposed approaches, can still struggle to achieve satisfactory performance, limiting its clinical applicability. As a possible so
In post-peace agreement Colombia, everyone declared war on the forest. In the Putumayo region, these wars take their own particular forms. Scientifically, the Putumayo is described as an Andean-Amazonic rainforest. For the indigenous and local inhabitants of the Putumayo, it is the Andean-Amazonic selva. We present three wars on the forest with material and discursive specificities and critically
Two ultimately thin vanadium-rich 2D materials based on VS2 are created via molecular beam epitaxy and investigated using scanning tunneling microscopy, X-ray photoemission spectroscopy, and density functional theory (DFT) calculations. The controlled synthesis of stoichiometric single-layer VS2 or either of the two vanadium-rich materials is achieved by varying the sample coverage and sulfur pres
OBJECTIVE: We investigated whether prepregnancy BMI (prePregBMI) in women with obesity was associated with differential DNA methylation (DNAm) in cord blood (CB) and whether DNAm may mediate the association of prePregBMI and early childhood BMI z score (BMIz).METHODS: From the Treatment of Obese Pregnant Women (TOP) study, 232 mother-child pairs were included. We conducted an epigenome-wide associ
Tertiary lymphoid structures (TLS) in the tumor microenvironment are prognostically beneficial in many solid cancer types. Reports on TLS in high-grade serous tubo-ovarian carcinoma (HGSC) are few, and the prognostic impact is unclear. We investigated mature TLS (mTLS), immature TLS (iTLS) and lymphoid aggregates (LA) in primary adnexal tumors (PTs) and synchronous omental/peritoneal metastases (p
Blind or low-vision (BLV) individuals often have reduced independent mobility, yet new aids fails in increasing it, are not adopted enough, or both. A major cause is a severe deficiency in how mobility aids are assessed in the field: there are no established methods or measures and those used often have poor relevancy, insight affordances, and reproducibility; probing how actual BLV participants r
Starting from a single layer of NbS2 grown on graphene by molecular beam epitaxy, the single unit cell thick 2D materials Nb5/3S3-2D and Nb2S3-2D are created using two different pathways. Either annealing under sulfur-deficient conditions at progressively higher temperatures or deposition of increasing amounts of Nb at elevated temperature result in phase-pure Nb5/3S3-2D followed by Nb2S3-2D. The
