Accurate fatigue life predictions of titanium alloy components requires an understanding of how the machining affected metallurgical and micro-mechanical subsurface condition influences fatigue crack nucleation and growth. This study investigates the influence of surface integrity features generated during carbide and high-speed polycrystalline diamond machining on the fatigue behaviour of coarse
Nickel (Ni)-promoted Molybdenum (Mo)-based catalysts are used for hydrotreatment processes in the chemical industry where the catalysts are exposed to high-pressure H2 at elevated temperature. In this environment, the catalyst transforms into the active phase, which involves the reduction of the oxide. Here, we report on the first in situ study on the reduction of alumina supported Ni- and Mo-base
An analytical method is developed for ultrasensitive detection of citrinin using double isothermal amplification and CRISPR-Cas12a. Gold nanoparticles (AuNPs) modified with antigen and thiol-terminated, single-strand DNA (ssDNA) are used as a probe. The antigen-modified AuNPs compete with citrinin to bind to magnetic beads coated with an anticitrinin antibody. After a simple magnetic separation, t
Congenital heart diseases (CHD) represent a major clinical and diagnostic challenge for correct abnormality identification and subsequent successful therapy; even more challenging is following-up patient health after multiple post-interventional corrections often required in complex cardio-vascular abnormalities. We describe a multi-modality imaging evaluation of a complex congenital cardio-vascul
Ph.D. training is an important mechanism for developing scientists who will serve our knowledge-based society. Because the quality of students who join Ph.D. programs significantly impacts the outcome of Ph.D. training, students’ career choices at this initial stage—whether to proceed to Ph.D. or not—are of crucial interest. This study investigates how students’ attributes and the local lab enviro
The human lung is a complex tissue consisting of a heterogeneous mix of different structures and cells, each which a specific role that together contribute to the primary function of the organ: the gas exchange. Different mesenchymal cells populate the interstitial areas around airways and blood vessels and form the connective tissue together with the extracellular matrix. Fibroblasts constitute o
Purpose: Positron emission tomography-computed tomography (PET-CT) using prostate-specific membrane antigen (PSMA) ligands is a method for imaging prostate cancer. A recent tracer, 18F-PSMA-1007, offers advantages concerning production and biokinetics compared to the standard tracer (68Ga-PSMA-11). Until now, radiation dosimetry data for this ligand was limited to the material of three healthy vol
Body-mounted accelerometers provide a new prospect for estimating power use in flying birds, as the signal varies with the two major kinematic determinants of aerodynamic power: wingbeat frequency and amplitude. Yet wingbeat frequency is sometimes used as a proxy for power output in isolation. There is, therefore, a need to understand which kinematic parameter birds vary and whether this is predic
The decarbonisation of energy systems is leading to a reconfiguration of the geographies of energy. One example is the emergence of community energy, which has become a popular object of study for geographers. Although widely acknowledged to be a contested, capacious, and flexible term, “community energy” is commonly presented as singular, bounded, and localised. In this paper, we challenge this c
Savannas cover a wide climatic gradient across large portions of the Earth’s land surface and are an important component of the terrestrial biosphere. Savannas have been undergoing changes that alter the composition and structure of their vegetation such as the encroachment of woody vegetation and increasing land-use intensity. Monitoring the spatial and temporal dynamics of savanna ecosystem stru
Prognostic analysis for early-stage (stage I/II) melanomas is of paramount importance for customized surveillance and treatment plans. Since immune checkpoint inhibitors have recently been approved for stage IIB and IIC melanomas, prognostic tools to identify patients at high risk of recurrence have become even more critical. This study aims to assess the effectiveness of machine-learning algorith
This dissertation explores two related advances in the production of twenty-first century pop music: first, the assimilation of practices and aesthetics from hip-hop and EDM (electronic dance music); second, the new generation of the digital audio workstation (DAW). This new type of DAW is increasingly part of global computational culture characterized by being ubiquitous, networked and device agn
We carried out deep mapping observations of the atomic hydrogen (H i) 21 cm line emission in a field centered on the famous galaxy group Stephan's Quintet (SQ), using the Five-hundred-meter Aperture Spherical Telescope (FAST) equipped with a 19-beam receiver. The final data cube reaches an H i column density sensitivity of 5σ = 2.1 × 1017 cm-2 per 20 km s-1 channel with an angular resolution of 4.
Characteristic modes of arbitrary 2-D periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and allows for characteristic modes to be computed from generic simulation or measurement data. Example calculations demonstrate the efficacy of the method through comparison against a periodic method of moments (MoM) formulation for a
Background: Higher gluten intake in childhood is associated with increased incidence of celiac disease autoimmunity (CDA) and celiac disease. It remains to be studied whether different dietary patterns independent of gluten intake contribute to the incidence. Objectives: This study aimed to explore associations of dietary patterns by age 2 y with risk of CDA and celiac disease in genetically susce
This article focuses on Egyptian interpretations of the atomic bombings of Hiroshima and Nagasaki by the US at the end of the Second World War. It surveys the reactions and responses of influential thinkers between 1945 and 1951, a crucial period prior to decolonisation. The objective of this research is to capture a specific moment in time and understand how it shaped imaginations of the future.
