“Here, We Are Middle Class”: Aspirational Materialities and Boundary Work in Self‐Constructed Neighborhoods in Bogotá

Sandra Pulido‐Chaparro

ABSTRACT Urban studies have tended to locate middle‐class urbanism in formally planned neighborhoods, while self‐built settlements are typically analyzed through frameworks of informality and poverty. This article challenges that dichotomy based on 5 years of ethnographic research in neighborhoods of informal origin in...

Bridging genetic knowledge gaps in a biodiversity hotspot through conservation training

Alba Enguídanos García · Víctor Cuesta-Porta · Jeancarlos Abrego L. · Milton Almanza · y 26 más

Abstract The Mesoamerican biodiversity hotspot is extraordinarily rich, yet most invertebrate genetic diversity remains invisible, hampering effective conservation planning amid accelerating biodiversity loss. How can this hidden diversity be revealed while simultaneously building local scientific capacity? Panama BioR...

Expert review and recommendations on the diagnosis and therapeutic management of eosinophilic granulomatosis with polyangiitis

Temperature‐Dependent and Temperature‐Independent Changes in Photosynthetic Traits Across the Day in the Tropical Tree Calophyllum inophyllum

Juan C. Mejía‐Medina · Roxana Alveo · Martijn Slot

ABSTRACT Tropical forests play a crucial role in global carbon cycling but face increasing stress from rising temperatures and atmospheric drought (vapor pressure deficit, VPD). While most studies assess photosynthetic performance at fixed time points, short‐term diurnal variation in photosynthetic parameters remains u...

Ultrametric Structures and Norm-Based p-Adic Operations for Hierarchical and Robust Information Processing

Anselmo Torresblanca-Badillo

In this article, we propose a non-archimedean framework for information processing based on the arithmetic and geometry of p-adic numbers. Exploiting the ultrametric structure of Qp, we introduce norm-based p-adic operations inspired by classical logical connectives that exhibit strong stability under perturbations. Th...
