Analysis of Cyclic Shear Stress–Displacement Mechanical Properties of Silt–Steel Interface in the Yellow River Delta

open access: yesJournal of Marine Science and Engineering, 2022
Pile foundations of offshore structures are often subjected to cyclic loads under storm loads, thus reducing their vertical bearing capacity. Therefore, studying the cyclic shear behavior of the soil–structure interface is important for maintaining the ...

Barrio morphology and private space: the social drivers of informal urban settlements in Caracas [PDF]

open access: yes, 2021
Urban morphology has historically been studied through the physical characteristics of a particular space. However, the urban form of a place is also influenced by relationships and social contexts.

Unsettled Urban Space: Routines, Temporalities and Contestations [PDF]

open access: yes, 2022
While urban life can be characterized by endeavors to settle stable and safe environments, for many people, urban space is rarely stable or safe; it is uncertain, troubled, imbued with challenges and perpetually under pressure.

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

From urban space to urban history—an introduction

open access: yes, 2020
While interest in urban space in the Roman world has boomed in recent decades, the debate has developed a strong emphasis on conceptual innovation, and this has limited the sensitivity of current discourse to historical change, so that debates about Roman urban space and Roman urban history have been developing without much interaction.

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

open access: yesAdvanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Cyclic constitutive equations of rock with coupled damage induced by compaction and cracking

open access: yesInternational Journal of Mining Science and Technology, 2022
In this paper, the cyclic constitutive equations were proposed to describe the constitutive behavior of cyclic loading and unloading. Firstly, a coupled damage variable was derived, which contains two parts, i.e., the compaction-induced damage and the ...

Urban Spaces

open access: yes, 2023
This entry offers some reflections on memory activism, with particular attention to ideological and structural transformation in cities, and changes in the way historical consciousness has been practically articulated in contemporary urban society. Studying urban memory activism offers a method to attain a more complex picture of the diverse agents in ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

open access: yesAdvanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.
