A Solution to Remove Railway Track Discontinuities at Spiral Junctions [PDF]

International Journal of Mechanical Engineering and Applications, 2020
To design railway track layouts, engineers use tangent and circle segments. To maintain curvature and bank angle continuities between flat straight lines, with zero curvature, and banked circles, they use spiral segments where curvature and bank angle vary linearly as function of distance.

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies

Rare Metals, EarlyView.
ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Implications of global distributive justice principles for implementation of the Kunming‐Montreal Global Biodiversity Framework

Conservation Biology, EarlyView.
Abstract In the era of the sixth mass extinction, reversing global biodiversity loss is of vital importance for life on Earth. In 2022, parties to the Convention on Biological Diversity (CBD) adopted the Kunming‐Montreal Global Biodiversity Framework (GBF), a strategic plan with 23 action‐oriented targets to be achieved by 2030.

Mapping High‐TDS Groundwater Near Impoundments Using Ground and Waterborne Towed Electromagnetics

Groundwater, EarlyView.
Abstract Long‐term monitoring at landfills and impoundments containing coal combustion products (CCPs) or other industrial wastes is essential for detecting possible leachate releases to groundwater and mapping contamination plumes. This study evaluates a novel, non‐invasive geophysical approach—towed time‐domain electromagnetic (TEM) surveys—for non ...

Trade costs, infrastructure, and dynamics in a global economy

International Journal of Economic Theory, EarlyView.
Abstract This study develops a dynamic two‐country model with trade costs linked to international infrastructure stock. With variable markups and firm heterogeneity, the welfare impact of trade costs depends on firms' cost distribution. Governments engage in a dynamic public investment game, leading to multiple steady states. The dynamic equilibrium of

“Queens of Ghost‐Land” 134 Years Later: Un‐Masking an Appalachian Witchcraft Accuser

The Journal of American Culture, EarlyView.
ABSTRACT In 1891, newspapers across America printed a story about witches in the Appalachian Mountains and the alleged powers they possessed to control their small farming community. The article was scathing in accusation and ultimately contributed to continued othering of the women profiled, increasing their visible vulnerabilities of class, gender ...

Language machines: Toward a linguistic anthropology of large language models

Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract Large language models (LLMs) challenge long‐standing assumptions in linguistics and linguistic anthropology by generating human‐like language without relying on rule‐based structures. This introduction to the special issue Language Machines calls for renewed engagement with LLMs as socially embedded language technologies.
