"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Role of glutathione and cysteine in acrylamide metabolism during in vitro and in vivo digestion

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background Acrylamide, a probable human carcinogen found in thermally processed potato products, is reactive towards amino and thiol compounds. This reactivity suggests acrylamide might react with them in the gastrointestinal tract resulting in mitigation of associated risk with acrylamide.

Trajectory Control of Manipulator Robots With Uncertainties: A Saturated Continuous Integral Sliding Mode Approach

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study addresses the trajectory tracking control for manipulator robots with uncertainties. The main objective is to ensure that the robot follows a desired trajectory despite the presence of uncertainties/disturbances and considering control input constraints. The approach is developed in the framework of continuous integral sliding modes.

Examination of Afghanistan's Development Traps

Regional Science Policy &Practice, EarlyView., 2022
Abstract We examine the factors behind Afghanistan's persistent underdevelopment. Drawing on various theories of development traps operating at the demographic, economic and institutional levels, we seek to assess whether and to what extent their functioning affects Afghanistan's development.
