Multi-Geometry InSAR Observations of the 2026 Mw 7.4 Chocó, Colombia Earthquake: NISAR and Sentinel-1 Coseismic Deformation, Decomposition, and Data-Quality Lessons

Ivan Lizarazo

We present coseismic deformation observations of the 10 August 2026 Mw 7.4 Chocó, Colombia earthquake from two independent L-band and C-band SAR missions: NASA-ISRO's newly operational NISAR and ESA's Sentinel-1. A NISAR ascending interferogram (24-day baseline) was initially degraded by an orbit-ephemeris misma...

Bounded Powers of Edge Ideals: Gorenstein Polytopes

Hibi, Takayuki · Fakhari, Seyed Amin Seyed

Let $S=K[x_1, \ldots,x_n]$ denote the polynomial ring in $n$ variables over a field $K$ and $I(G) \subset S$ the edge ideal of a finite graph $G$ on $n$ vertices. Given a vector $\mathfrak{c}\in\mathbb{N}^n$ and an integer $q\geq 1$, we denote by $(I(G)^q)_{\mathfrak{c}}$ the ideal of $S$ generated by those monomials b...

From Patient to Household: Retrospective Cohort and Clinical and Economic Evaluation of H. pylori Family Management

Castaño-Llano, Rodrigo · Díaz-Quintero, Camilo · Alvarez-Barrera, Oscar

This study evaluates a family-based strategy for the management of Helicobacter pylori infection compared with conventional index-case-only management in a Colombian household-based observational cohort with 24 months of follow-up. The family-based approach included systematic screening of household members and eradica...

Filling the gap in termite community structure and diversity in northern Neotropical Savannas

L-Pareja, Juan Esteban

Song divergence and a gleaming white iris reveal four species in a widespread Neotropical understory bird ( Clibanornis rubiginosus , Furnariidae)

Juan Villamizar · Andrés Cuervo

Abstract Polytypic species with large ranges may harbor unrecognized diversity because taxonomy ranks populations differing subtly in plumage as subspecies. The Ruddy Foliage-gleaner ( Clibanornis rubiginosus ) exemplifies this problem. It ranges from Mexico to Brazil, with 15 subspecies, and forms a non-monophyletic c...
