High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

Structural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

Structural Concrete, EarlyView.
Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental design situations due to the lack of suitable equivalent approaches ...

Gas-sieving zeolitic membranes fabricated by condensation of precursor nanosheets

, 2019
The synthesis of molecular-sieving zeolitic membranes by the assembly of building blocks, avoiding the hydrothermal treatment, is highly desired to improve reproducibility and scalability.

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

Boreas, EarlyView.
Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history.

Advanced Sieve Methods for Twin Primes: Nonlinear Weight Functions and Density Optimization

We develop a comprehensive framework for twin prime detection combining three innovative approaches:(1) a novel characterization through the G-function on bracketing even numbers, (2) optimized bilinearweight functions improving the twin prime constant by 10%, and (3) efficient modular filters for candidateselection.

Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications

Computer Graphics Forum, EarlyView.
Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

Influence of Trap Apparent Silhouette, Canopy Cover and Their Interaction on the Capture of Forest Coleoptera

Journal of Applied Entomology, EarlyView.
ABSTRACT Bark beetles and woodboring beetles can be serious forest pests and are often monitored using semiochemical‐baited flight intercept traps. Although factors like trap placement and silhouette are known to influence beetle capture, the interaction of these variables remains poorly understood.
