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

Advanced 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.

Place (un)making through soft urban densification: exploring local experiences of density and place attachment in Tehran

International Journal of Urban Sustainable Development, 2023
The relationship between urban density and social conditions in urban areas has received increasing attention in recent research. However, there is a lack of understanding of the dynamics between urban densification and these social conditions from a ...

Urbanization and structural transformation [PDF]

, 2020
Chapter 12, “Urbanization and Structural Transformation,†describes patterns of urbanization in Ethiopia and government policy to promote development of secondary cities. Official population data indicate rapid urban growth, 4.2 percent per year between 1994 and 2015, far outpacing the overall population growth rate of 2.5 percent.

Orbital Electrowetting: From Continuous Droplet Transport to Programmable Microfluidics

Advanced Materials, EarlyView.
This work comprehensively summarizes the mechanisms, recent advances, potential applications, and key challenges of orbital electrowetting. It highlights that integrating orbital electrowetting with conventional electrowetting is required to enable complete digital‐microfluidic workflows while simplifying platform architecture.

Stress-mediated multi-fault rupture dynamics of the 2023 Kahramanmaraş earthquake sequence, Türkiye

Scientific Reports
The 2023 Kahramanmaraş (M7.8) and Elbistan (M7.6) earthquakes in Türkiye provide a profound case study in multi-fault rupture dynamics. We update a pre-existing Coulomb stress model¹ to analyse the historical and immediatestress conditions that caused ...

Resource-based cities: Spatial structure and evolutionary identification based on nighttime light images

Frontiers in Earth Science, 2022
Dividing the development stage and grasping the best time to transition are significant for resource-based cities (RBCs). However, there is still a lack of research on how to judge the developmental stage of RBCs through objective indicators of urban ...

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

Advanced 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.
