Compositional tuning of gas-phase synthesized Pd–Cu nanoparticles

Bimetallic nanoparticles have gained significant attention in catalysis as potential alternatives to expensive catalysts based on noble metals. In this study, we investigate the compositional tuning of Pd–Cu bimetallic nanoparticles using a physical synthesis method called spark ablation. By utilizing pure and alloyed electrodes in different configurations, we demonstrate the ability to tailor the

Media Framing of Black Women's Campaigns for the US House of Representatives

How are Black female candidates’ race and gender represented in newspaper coverage of electoral campaigns? Are intersectional stereotypes of Black women in general reflected in representations of Black women in elite politics? This study employs an open ended qualitative content analysis of coverage of the 2012 general election to consider the way in which racial and gendered references frame the

The 2009 British MPs’ expenses scandal: Origins, evolution and consequences

This chapter introduces the British MPs’ expenses scandal: its origins, evolution and consequences. We argue that despite some early predictions, the scandal was limited in its impact: the purported ‘revolution’ never occurred. We briefly review the comparative literature on the political impact of scandal, which illustrates why the effects of scandals are usually limited and reasons why voters ma

From Silos to Synergy: Learning from Politically Informed, Gender Aware Programs

This paper draws together reflections, approaches and practical lessons from 151 development programs that are, in various ways, seeking both to be gender aware and to understand and engage with power and politics. It aims to provide food for thought for donor organisations and development programs. Gender aware programming has been on the development agenda for at least a generation. Most donor o

Generation of aerosols by noninvasive respiratory support modalities : a systematic review and meta-analysis

Importance: Infection control guidelines have historically classified high-flow nasal oxygen and noninvasive ventilation as aerosol-generating procedures that require specialized infection prevention and control measures. Objective: To evaluate the current evidence that high-flow nasal oxygen and noninvasive ventilation are associated with pathogen-laden aerosols and aerosol generation. Data Sourc

An experimental study on lung deposition of inhaled 2 μm particles in relation to lung characteristics and deposition models

Background: The understanding of inhaled particle respiratory tract deposition is a key link to understand the health effects of particles or the efficiency for medical drug delivery via the lung. However, there are few experimental data on particle respiratory tract deposition, and the existing data deviates considerably when comparing results for particles > 1 μm. Methods: We designed an experim

Airspace Dimension Assessment for early detection of lung function impairment in the peripheral airways of firefighters

Introduction Firefighters have increased risk of chronic respiratory disease. Standard clinical techniques used in medical checkups may not detect the earliest microstructural changes in peripheral airways. A new technique called Airspace Dimension Assessment (AiDA) has been shown to enable early detection of emphysema in COPD. This method may be useful in the occupational setting to detect early

Differential tt¯ cross-section measurements using boosted top quarks in the all-hadronic final state with 139 fb−1 of ATLAS data

Measurements of single-, double-, and triple-differential cross-sections are presented for boosted top-quark pair-production in 13 TeV proton–proton collisions recorded by the ATLAS detector at the LHC. The top quarks are observed through their hadronic decay and reconstructed as large-radius jets with the leading jet having transverse momentum (pT) greater than 500 GeV. The observed data are unfo

Rates of Progression in Patients with Alzheimer’s Disease Depending on Apolipoprotein E Genotype and Concomitant Medications.

Background: The apolipoprotein E (APOE) ε4 allele is associated with higher cholesterol levels, and an increased risk of developing Alzheimer’s disease (AD) and amyloid-related imaging abnormalities after initiation of amyloid-modifying therapies. A worse cognitive response to cholinesterase inhibitor (ChEI) treatment and longitudinal outcome in APOE ε4-carriers has been observed. Based on these c

Aberrant activation of TCL1A promotes stem cell expansion in clonal haematopoiesis

Mutations in a diverse set of driver genes increase the fitness of haematopoietic stem cells (HSCs), leading to clonal haematopoiesis1. These lesions are precursors for blood cancers2-6, but the basis of their fitness advantage remains largely unknown, partly owing to a paucity of large cohorts in which the clonal expansion rate has been assessed by longitudinal sampling. Here, to circumvent this

The geometric albedo of the hot Jupiter HD 189733b measured with CHEOPS

Context. Measurements of the occultation of an exoplanet at visible wavelengths allow us to determine the reflective properties of a planetary atmosphere. The observed occultation depth can be translated into a geometric albedo. This in turn aids in characterising the structure and composition of an atmosphere by providing additional information on the wavelength-dependent reflective qualities of

Temperature-induced DNA density transition in phage λ capsid revealed with contrast-matching SANS

Structural details of a genome packaged in a viral capsid are essential for understanding how the structural arrangement of a viral genome in a capsid controls its release dynamics during infection, which critically affects viral replication. We previously found a temperature-induced, solid-like to fluid-like mechanical transition of packaged λ-genome that leads to rapid DNA ejection. However, an

Discovery of TOI-1260d and the characterization of the multiplanet system

We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 d, respectively. The nature of the third transiting planet with a 16.6-d orbit is supported by ground-based follow-up observations, including time-series photometry, high-angular resolution images, spectroscopy, and archival ima
