Characterization of Rain Attenuation for Millimeter Wavelengths for Realistic Nonrotational Symmetric Drop Shapes

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The use of frequencies above 30 GHz (millimeter waves) for communication purposes is nowadays a necessity, both for terrestrial (e.g., 5G/6G) and satellite links. One reason is the need for more bandwidth and the fact that “traditional” frequency bands are already fully occupied.

Revealing Airflow–Particle Dynamics in Dry Powder Inhalers

Small, EarlyView.
An integrated framework combining device and formulation characterization, CFD–DEM simulations, and interpretable machine learning is established. This framework reveals how airflow and particle interactions govern powder dispersion across prevailing dry powder inhalers.

Spatial Statistics for Screening Molecular Structures

Small, EarlyView.
Deep architectures for materials discovery demand vast training data and obscure the structure‐property link. This review shows how spatial statistics offer a physically grounded alternative: voxelized fields and two‐point correlations, compressed by principal component analysis, yield convex, interpretable descriptors. Lean surrogates then reach sub‐2%

Numerical Study of Argon Bubble Transport and Entrapment in Continuous Casting Using a Multiphase Approach

steel research international, EarlyView.
Bubble transport in continuous casting is controlled by the interaction of bubble size, flow dynamics, and operating conditions. Critical regions governing bubble escape and entrapment are identified, revealing the mechanisms responsible for defect formation and providing practical guidance for process optimization. Argon injection is often used in the

Serviceability reserves of historic reinforced concrete slabs implications for structural reuse

Structural Concrete, EarlyView.
Abstract The transition to a circular economy in the construction sector requires reliable methods to assess whether existing reinforced concrete elements can be reused in new load‐bearing structures. A central question is whether slabs designed according to historical standards also meet today's serviceability requirements.

Integrating Chemical, Electrical, and Photonic Effects Into a Unified ETOP‐Based Plasma Dose Framework

High Voltage, EarlyView.
ABSTRACT In plasma medicine and biological applications, plasmas typically deliver a complex combination of reactive chemical species and multiple physical energy components. However, establishing a unified and comparable dose metric to characterise their integrated biological effects remains a major challenge that continues to limit progress in this ...

Towards quantum crystallographic description of incommensurately modulated structures

Acta Crystallographica Section A, EarlyView.
A modification of the structure‐factor equation for incommensurately modulated structures is proposed to enable structure description with non‐spherical atomic form factors.In this contribution, a slight modification of the structure‐factor equation for incommensurately modulated structures is proposed in order to enable structure description with non ...

The Capital Gains Conundrum: On a Divergence of Green From Traditional Accounting

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Understanding the concept of income and recording it correctly are elemental to economic analysis. A controversy about whether capital gains are a form of income has arisen in green accounting. Virtually all economists assume that at each time there is a unique price of capital from which a capital gain can be calculated.
