Mapping structural heterogeneity in three-dimensional biophotonic gyroid networks using position-resolved small-angle X-ray scattering

Abstract The wings of select Papilionid and Lycaenid butterflies contain a three-dimensional gyroid network of a solid cuticle phase in air. In butterfly scales, gyroid networks are optically interesting, as they create the green colour observed in the wings of these butterflies....

A framework to compare the performance of spatial disaggregation methods of statistical climate downscaling in South America

Study region Chile and South America. Study focus Climate change is simulated at a coarse scale with General Circulation Models. Impact and regional studies require downscaling to increase spatial resolution. Several downscaling methods exist, but most studies do not analyze or c...

Analysis of Injector Staging Patterns With Comparisons of Limit Cycle Amplitudes Over a Full Domain of Operation

Abstract Injector staging has recently been demonstrated to control thermoacoustic instabilities in an annular combustor, but its effects were investigated at a single operating point. This work extends this concept to a wide operating domain comprising a range of thermal powers...

Accelerating charging dynamics of electric double-layer capacitors

Electric double-layer capacitors (EDLCs), consisting of an ionic fluid between two metallic electrodes, are electrochemical energy storage devices complementary to batteries, allowing for a faster charge/discharge. The charging dynamics in response to a voltage step features a va...

Power-law creep in C–S–H emerging from subdiffusive dynamics

Power-laws have long been used to describe creep in cementitious systems, from C-S-H to concrete, yet their mechanistic origin remains unclear. Diffusion, layer sliding, and permeation are often invoked as microscopic drivers of creep in C-S-H, but it is uncertain whether these r...

Gluon production in the color glass condensate from BCFW recursion

A bstract In the Color Glass Condensate framework, the colliding projectiles are described as classical color currents. Gluon production at leading order in the coupling is obtained from the retarded solution of the classical Yang-Mills equations, with these currents acting as so...

Prospective analysis of pre-diagnostic untargeted plasma metabolomics and risk of triple-negative breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Triple-negative breast cancer (TNBC) accounts for 10–15% of newly diagnosed breast cancer, and its aetiology is poorly understood compared to other breast cancer subtypes. We applied untargeted metabolomics to identify novel biological pathways associated with TNBC risk and poten...

Lost in Translation: Interprofessional Variability in Understanding Pro Re Nata (PRN) Prescribing in Geriatric Practice—A Prospective Observational Study

Background/Objectives: Medication safety is a critical concern in older adults due to age-related vulnerability, multimorbidity, and polypharmacy. Pro Re Nata (PRN, “as needed”) prescribing is common in geriatric care but may be interpreted inconsistently across healthcare profes...

The impact of prescriptions in phenomenological extractions of transverse momentum dependent distributions

Abstract We investigate the impact of phenomenological prescriptions in the Collins–Soper–Sterman (CSS) approach for global extractions of Transverse Momentum Distributions (TMDs). We show that fits to low-energy Drell–Yan data with different choices of $$b_*$$ <mml:math xmlns:mm...

Brick kilns across India: A temporal analysis of brick kiln distribution and technology types

Thousands of brick kilns operate across India, significantly contributing to air pollution and CO 2 emissions due to outdated practices and non-compliance with environmental standards. Regulations promoting cleaner kiln technologies have been introduced, yet detailed information...

Win ratio analysis of surgical approaches for lung cancer: a nationwide observational study using the French national hospital discharge database

Minimally invasive surgical approaches have gained widespread adoption, yet comparative evidence integrating multiple hierarchical endpoints remains limited. Our objective was to compare the surgical approaches for lung cancer resection (thoracotomy, VATS, robot-assisted surgery)...

Visible mould and blood inflammatory phenotypes of asthma in adults: the CONSTANCES cohort

Studying the associations between indoor mould contamination and blood inflammatory phenotypes may provide further insight into the mechanisms by which this environmental factor affects asthma. Among 1870 adults with current asthma from a population-based cohort, 29.6% reported v...

Experimental Investigation of Pressure Influence On A Swirled Stabilized Premixed Hydrogen-Air Flame For Aeronautical Applications Using Optical Diagnostics

Abstract Reducing carbon footprint of the aviation sector is essential for its sustainability. A promising solution for short-to-medium-haul flights is to replace kerosene with hydrogen combustion. This switch leads to significant changes in the architecture of the combustion cha...

Electrical control of exchange bias in sub-10 nm regime enabled by single-nanotube patterning

Achieving stable magnetization in sub-10 nm ferromagnetic layers represents a fundamental bottleneck in spin-orbit torque magnetic random-access memory development. While exchange bias potentially offers stabilization at such scales through antiferromagnetic coupling, conventiona...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Accelerating biomass loss from forest disturbances across Europe

Abstract Forest disturbances are rising globally due to climate change and land-use pressures, weakening the terrestrial carbon sink. However, declines in aboveground biomass from tree cover loss remain poorly quantified, limiting our understanding of the role of disturbances in...

Scaling up fabrication of thin-film nanocomposite (TFN) membranes: Methods, challenges, and applications

Abstract Thin-film nanocomposite (TFN) membranes have received significant attention because of their excellent separation performance, structural flexibility, and tunability. As the demand for high-efficiency membrane technologies in industry grows, it becomes imperative to tran...

Peptide-targeted cubosome and hexosome nanoassemblies mitigate mitochondrial dysfunction in a MitoPark model

Mitochondrial dysfunction is a primary pathogenic mechanism underlying dopaminergic neuron loss in the nigrostriatal pathway in Parkinson's disease (PD). To investigate mitochondrion-targeted therapeutic strategies, we utilized the MitoPark mouse model, in which mitochondrial tra...

Accelerating Translation of NK Cell Therapies to the Clinic: A European Perspective

Adoptive immunotherapies have emerged as a promising strategy in the treatment of hematological malignancies. To date, seven chimeric antigen receptor (CAR)-T cell products have obtained market authorization in Europe for B-cell malignancies, where they have revolutionized treatm...
