Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

open access: yesStructural Concrete, EarlyView.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Robotic Cell Micromanipulation Skill Learning via Imitation‐Enhanced Reinforcement Learning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Humans can learn complex and dexterous manipulation tasks by observing videos, imitating and exploring. Multiple end‐effectors manipulation of free micron‐sized deformable cells is one of the challenging tasks in robotic micromanipulation. We propose an imitation‐enhanced reinforcement learning method inspired by the human learning process ...

The agency of a marmalade machine: Gender, class and mechanical gadgets in the British Kitchen, c.1870–1938

open access: yesGender &History, EarlyView.
Abstract This article explores the marmalade machine, a mechanical device designed to slice orange peel. These niche objects were manufactured between roughly 1870 and 1938 in Britain. As a so‐called ‘labour‐saving’ gadget, the marmalade machine sliced orange peel quickly and effectively, removing the tedious process of slicing orange peel by hand ...

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

open access: yesArabian 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.
