Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Impact‐diagnostic criteria for use in confirming a meteorite impact origin of terrestrial geological structures: Recommendations by the Impact Cratering Committee of the Meteoritical Society

Meteoritics &Planetary Science, EarlyView.
Abstract The framework of the Impact Cratering Committee (ICC) of the Meteoritical Society was approved in 2020, with the first committee members appointed in 2023. The ICC has a mandate to (1) approve, maintain, and update a database of confirmed terrestrial meteorite impact structures, (2) define and regularly update the criteria used for ...

Equal Time, Unequal Labor Division: Adolescents' Domestic Labor Time During the COVID‐19 Pandemic

Sociological Inquiry, EarlyView.
While existing research offers mixed evidence on how the COVID‐19 pandemic affected adults' division of housework, adolescents have remained largely overlooked in this regard. Using nationally representative data from the 2019–2021 American Time Use Survey and Current Population Survey, this study examines changes in adolescents' unpaid labor before ...

Determinants of Productivity and Sustainability in Small‐Scale Dairy Industries: Evidence From the Salale Zone of Oromia, Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Small‐scale dairy productivity in Ethiopia is significantly shaped by socio‐economic, institutional and climatic factors. Education, land ownership, infrastructure and veterinary access enhance performance, while market inefficiencies, feed costs and climate variability constrain success, underscoring the need for integrated interventions to improve ...

Iterative Construction of Reversible Variable-Length Codes and Variable-Length Error-Correcting Codes

, 2004
We propose a generic algorithm for the construction of efficient reversible variable-length codes (RVLCs) and variable-length error-correcting (VLEC) codes, which optimizes the codeword length distribution.

Arithmetic coding revisited

, 1998
Over the last decade, arithmetic coding has emerged as an important compression tool. It is now the method of choice for adaptive coding on multisymbol alphabets because of its speed, low storage requirements, and effectiveness of compression.

Advancing Toward Gray Zone: Evaluation of Tropical Cyclones in Key Basins With the 12.5 km High Resolution CAS FGOALS‐f3 Model

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract State‐of‐the‐art climate models are approaching gray‐zone resolutions that can improve the representation of tropical cyclones (TCs), but the extent of these gains remains uncertain. This study evaluates the effect of spatial resolution, particularly near the gray‐zone, using three resolution configurations of the Chinese Academy of Sciences ...

Self-dual codes over F2+uF2 with an automorphism of odd order

, 2009
We complete the classification of all Lee-extremal and Lee-optimal self-dual codes over F2+uF2 of lengths 9 through 20 that have a nontrivial odd order automorphism begun in [W.C.

Digital Marketing Tactics, Non‐Compliance With the International Code of Marketing of Breastmilk Substitutes and Legal Breaches of Code‐Based Legislation by the Commercial Milk Formula Industry in Central America and the Caribbean

Maternal &Child Nutrition, Volume 22, Issue 3, July 2026.
ABSTRACT Digital marketing has become the dominant channel for the promotion of commercial milk formula (CMF), accounting for most consumer exposure in many settings. This study characterized the digital CMF marketing landscape in Guatemala, Panama, and the Dominican Republic, identified prevalent promotional tactics, and assessed non‐compliance with ...
