Krypton-sputtered tantalum films for scalable high-performance quantum devices
Abstract Superconducting qubits and microwave resonators based on tantalum thin films have recently demonstrated large increases in performance. This makes Ta an attractive material for superconducting quantum computing applications, but so far direct deposition has largely relied on high substrate temperatures exceeding 400 °C to achieve the cubic (bcc) phase of tantalum.
Emissions Reductions at Coal Power Plants Continue to Offer Routes to Meet New US PM 2.5 Standards Click to copy article link Article link copied!
Introduction Click to copy section linkSection link copied! In 2024, the United States Environmental Protection Agency (EPA) promulgated a new health-based National Ambient Air Quality Standards (NAAQS) for PM2.5, set at 9 μg/m3. (1) This standard sparked legal challenges from several states, which argued that the EPA has disregarded the economic implications of setting these stringent PM2.5 standards, even though the Clean Air Act (CAA) states that NAAQS should be health-based.
Increased contributions of climate-driven wildfires to nitrogen deposition in the United States - Communications Earth & Environment
Abstract Climate change and increases in the frequency and severity of climate-driven wildfires, particularly in the western United States, has serious ramifications for enhanced downwind reactive nitrogen (Nr) emissions, deposition, and critical load exceedances.
Global Ensemble Fire Emission Product Version 1.0 (EnsemFire V1.0) - Scientific Data
Abstract This paper presents EnsemFire v1.0, a global ensemble fire emission dataset that provides daily emissions at 0.1° × 0.1° spatial resolution for key air pollutants like fine particulate matter (PM₂.₅), black carbon (BC), organic carbon (OC), carbon monoxide (CO), ammonia (NH₃), nitrogen oxides (NOx), and sulfur dioxide (SO₂), greenhouse gases including carbon dioxide (CO₂) and methane (CH₄), and fire radiative power (FRP).
Ablative Techniques for Lung Metastases: Outcomes of Patients Treated with Stereotactic Radiotherapy and Radiofrequency Ablation
You are already at the latest version Stereotactic radiotherapy (SBRT) and radiofrequency ablation (RFA) are common ablative techniques for lung metastases. Retrospective review of all patients treated with either modality at a single institution between 2011 and 2019 was conducted. Baseline characteristics and outcomes were compared. Local and distant progression, and overall survival were estimated using the Kaplan Meier method.
Regime shift in secondary inorganic aerosol formation and nitrogen deposition in the rural United States - Nature Geoscience
Abstract Secondary inorganic aerosols play an important role in air pollution and climate change, and their formation modulates the atmospheric deposition of reactive nitrogen (including oxidized and reduced nitrogen), thus impacting the nitrogen cycle. Large-scale and long-term analyses of secondary inorganic aerosol formation based on model simulations have substantial uncertainties.
Anaplastic lymphoma kinase-positive pulmonary inflammatory myofibroblastic tumour: a case report - Journal of Medical Case Reports
An 18-year-old Caucasian man presented to his local hospital with acute shortness of breath (T = 0). Physical examination showed marked reduction in air entry to the left lung. Chest X-ray showed left lung collapse. Five years prior to this, he started experiencing episodic breathlessness and was eventually diagnosed with asthma. He was initiated on inhalers which did not provide significant symptomatic relief.

Danger in the Dust! The Hazards of Windblown Dust
Editors’ Vox is a blog from AGU’s Publications Department. Dust comprises small particles (about 50 microns or smaller in diameter) of sediment or soil which are suspended in the atmosphere and transported by the wind. While these small airborne particles may seem benign, they pose a significant threat to human and environmental health, transportation safety, and the global economy.
aerosols & particles
Posted inEditors' Vox Airborne dust not only causes disease, it also menaces transportation on land, sea, and air; disrupts renewable energy systems; transports pathogens and toxic substances; and poses many other hazards. Posted inResearch Spotlights by InMAP estimates air pollution within cities, but its predictions are flawed for specific chemicals. Now, scientists are addressing that shortcoming.
How Many People Were Killed by Windblown Dust Events in the United States?
Keywords: Atmosphere; Social Science; North America; Aerosols; Particulates; Visibility Windblown dust events, including both dust storms (visibility < 1 km) and smaller, localized events from deserts, fallow farmlands, and construction sites, pose severe risks to public health and transportation safety. Exposure to dust particles has been associated with a variety of adverse health effects, including respiratory disease (Gross et al. 2018), cardiovascular mortality (Crooks et al.

Using Maths to Rig Elections
A disconcerting distribution Our crooked conspirator above was right in thinking that their randomly selected numbers will be uniformly distributed, in that each outcome is equally likely, and hence patternless. However, they made a mistake: populations, street addresses, the figures appearing in the Financial Times, number of leaves on trees — any natural population of numbers — also obey a less intuitive rule that takes more work to fake.
How Beethoven continues to fuel the creativity of composers today
Introducing Vol 2 of 'Beethoven Plus', where new music is inspired by Beethoven's Violin Sonatas In 2014, Krysia Osostowicz and I were working on the cycle of 10 Beethoven Sonatas for Violin and Piano, on that kind of musical high that comes from immersion in the depths of fathomless art.

Impact of Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) and AirNow PM
In this study, MODIS AOD and AirNow PM measurements are assimilated into the CMAQ model using an optimal interpolation (OI) method. Over a 30-day test period in July 2011, three assimilation configurations were used in which MODIS AOD and AirNow PM measurements were first assimilated separately before being assimilated simultaneously. The background error covariance is estimated using both the NMC approach and the Hollingsworth-Lönnberg method.
