Binary nanoparticles (BNPs), composed of two distinct materials, offer tailored properties advantageous for various applications, including enhanced catalytic, magnetic, and optical behavior. Among the synthesis methods for BNPs, spark ablation stands out for its capability to produce multicomponent nanostructures with tunable compositions. This study investigates the mixing dynamics of material v
This chapter takes an interest in the construction of gendered knowledge in the digital space. Through an analysis of the digital activism of the epistemic agent Nadia Murad, survivor of the genocide against the Yazidi, the chapter investigates how she departs from her personal, embodied experience of ISIS violence to advocate for justice, recognition and reparation. Through the methodological app
Finding local features that are repeatable across multiple views is a cornerstone of sparse 3D reconstruction. The classical image matching paradigm detects keypoints per-image once and for all, which can yield poorly-localized features and propagate large errors to the final geometry. In this article, we refine two key steps of structure-from-motion by a direct alignment of low-level image inform
This Letter presents a differential cross-section measurement of Lund subjet multiplicities, suitable for testing current and future parton shower Monte Carlo algorithms. This measurement is made in dijet events in 140 fb−1 of s=13 TeV proton–proton collision data collected with the ATLAS detector at CERN's Large Hadron Collider. The data are unfolded to account for acceptance and detector-related
The associated production of Higgs and W bosons via vector-boson fusion is highly sensitive to the relative sign of the Higgs boson couplings to W and Z bosons. In this Letter, two searches for this process are presented, using 140 fb^{-1} of proton-proton collision data at sqrt[s]=13 TeV recorded by the ATLAS detector at the LHC. The first search targets scenarios with opposite-sign couplings o
The planetary system K2-24 is composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large transit time variations (TTVs), and it is an excellent laboratory to search for signatures of planetary migration. Previous studies performed with K2, Spitzer, and RV data tentatively claimed a significant non-zero eccentricity for one or both planets, possibl
BACKGROUND: The COVID-19 vaccination campaign in several European countries involved collaboration between public health and Primary Health Care (PHC). OBJECTIVE: To highlight the role of PHC professionals in the COVID-19 vaccination rollout, specifically in terms of vaccine administration, communication and contributing to vaccination population coverage. METHODS: A descriptive retrospective stud
Background: University students are at a transitional stage in life characterized by increased independence, autonomous decision-making, reduced parental supervision, and heightened susceptibility to peer pressure.These dynamics expose them to various risks, including risky sexual behaviors, violence, and use of substances and alcohol. These risky behaviors often result in serious negative consequ
BACKGROUND AND OBJECTIVE: Nonmetastatic (M0) clear cell renal cell carcinoma (ccRCC) recurs in ∼20% of patients within 5 yr after surgery. With no biomarkers available, recurrence detection relies on radiological imaging. Urine glycosaminoglycan profiles (GAGomes) were previously associated with M0 ccRCC recurrence. We conducted an observational prospective multicentre diagnostic test cohort study
Over the last decade it has been pointed out by several philosophers that not all Status Function Declarations are synchronic: some such declarations are directed toward the absolute past. Such Status Function Declarations are perplexing if one is an ontic realist with respect to institutional properties and states of affairs. If successful, such Status Function Declarations seem to change the absOver the last decade it has been pointed out by several philosophers that not all Status Function Declarations are synchronic: some such declarations are directed toward the absolute past.

Since the introduction of the RUT tax deduction in 2007, the market for private domestic care services has grown rapidly in Sweden. Today, deductions can be made for cleaning and gardening, as well as for care services such as going for walks, providing companionship, assisting with dressing, and helping with personal hygiene. One main group that make use of the tax deduction are elderly over the
The increased accuracy of the experiments studying parity non-conserving effects in atoms calls for improvement also in the atomic calculations which are necessary to connect the experimental results to fundamental parameters. We show how the method of iterative solution of the two-dimensional “pair equation” can be used to treat the effect of pair correlation to all orders, also in the calculatio
The search for weak-interaction-induced atomic parity nonconservation, initiated in the 1970s, challenges both theory and experiment Since the weak interaction is very short range, the atomic effects increase rapidly with nuclear charge, as Z3. The focus has thus been on heavy atoms, where relativistic effects are essential, and nuclear size must be taken into account. The generalization of atomic
Current physics textbooks tend to exclude military applications, but it is explained here how a study of the Manhattan project-the devastatingly successful attempt to develop an atomic bomb-can show students how the lives and work of physicists are shaped by events in society. Much of the original source material is available in books and on the internet (and referenced here), which allows student
Many modern rollercoasters feature loops. Although textbook loops are often circular, real rollercoaster loops are not. In this paper, we look into the mathematical description of various possible loop shapes, as well as their riding properties. We also discuss how a study of loop shapes can be used in physics education.
A carousel gives possibilities to explore physics in rotating systems and to gain first-hand experience of methods to measure rotation, without the need for an external reference. This paper discusses the Foucault pendulum, as well as the sideways deflection of horizontally and vertically moving objects in a rotating system. These experiments lay the foundation for an understanding of ways to demo
