Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

ADAPT: An Autonomous Forklift for Construction Site Operation
Journal of Field Robotics, EarlyView.ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.

Four Questions for Ethnographers Under Trumpian Authoritarianism
American Anthropologist, EarlyView.ABSTRACT This article examines evolving challenges and ethical dilemmas facing ethnographers working under intensifying authoritarianism in the United States. Because very little of what the United States is experiencing is new, my work here is primarily curatorial in nature, drawing upon the lessons offered by scholars across disciplines in the United
