Abstract Shrinking cities are increasingly drawing global attention, but urban shrinkage is seldom considered as an enduring structural condition necessitating a move beyond growth‐centric strategies. The focus often remains on mitigating symptoms rather than embracing the broader implications of long‐term decline. Understanding of what drives decision‐

Articulating Sovereignties: Struggles for Subaltern Hegemony in Ecuador and Bolivia
ABSTRACT This article examines the cycles of articulation and disarticulation between working‐class and indigenous‐campesino movements in Ecuador and Bolivia. While the former advances national‐popular sovereignty, aiming to strengthen the state against imperialism, the latter defends community‐territorial sovereignty against internal colonialism ...

Unimodular Einstein--Cartan gravity: Dynamics and conservation laws
Unimodular gravity is an interesting approach to address the cosmological constant problem, since the vacuum energy density of quantum fields does not gravitate in this framework, and the cosmological constant appears as an integration constant.

Crisis beyond the exceptional: The latent, everyday nature of the crisis perpetual
We are surrounded by declarations of crises, from climate to housing, debt and beyond. Crisis is everywhere and yet it remains exceptional. A crisis is imagined as a call to action, a repudiation of the old system, promising change if only the moment can be seized.

Effective Theory Approach to the Spontaneous Breakdown of Lorentz Invariance [PDF]
We generalize the coset construction of Callan, Coleman, Wess and Zumino to theories in which the Lorentz group is spontaneously broken down to one of its subgroups.

Phase‐Field Fracture Simulation of Pressurized Concrete Microstructure
ABSTRACT Pressurized cracks in concrete have a significant impact on the safety and durability of concrete structures. The peak strength of concrete is reduced in the presence of pressurized cracks. However, conducting pressure‐coupled strength evaluation experiments requires extensive effort, and simulation tools can complement the time‐consuming and ...

Comparative Study on Prediction Models for Crack Opening Degree in Concrete Dam
In recent years, classical statistical models and machine learning models have been developed in parallel in the field of dam safety monitoring. However, there are some deficiencies in the predictive power of the former and the theoretical explanation of

Dynamic Analysis of Concrete Arch Dam due to Earthquake Force [PDF]
A gravity dam with concrete is a vast construction that keeps a large volume of water on its upstream side, and its ability to withstand seismic vibrations is critical.
