Ideal intrinsic extensions with connections to PI-rings [PDF]
In this paper, we extend various classical results by Armendariz and Steinberg, Fisher, Kaplansky, Martindale, Posner, and Rowen on semiprime PI-rings. We do this by introducing several new generalizations of the class of semiprime PI-rings.

On Jacobson And Nil Radicals Related To Polynomial Rings [PDF]
This note is concerned with examining nilradicals and Jacobson radicals of polynomial rings when related factor rings are Armendariz. Especially we elaborate upon a well-known structural property of Armendariz rings, bringing into focus the Armendariz ...

Diversity Hotspots and Vulnerability of Pine Species in the Sierra Madre Occidental, Western Mexico
The present study employs a modeling approach to examine the current and future distribution of 19 pine species in the Sierra Madre Occidental, Mexico. This was done in order to identify areas with high potential for pine species richness and to determine which species are at risk due to climate change under different projections.

Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

The ‘slow‐burn effect’ of human trafficking following disaster
Abstract A disaster is frequently cited as a driver of human trafficking, with claims that earthquakes, tsunamis, or typhoons create a chaotic post‐calamity environment ripe for traffickers to recruit their victims. Theory suggests that increased poverty, displacement, and a breakdown of law and order contribute to this situation.

SOME EXAMPLES OF ARMENDARIZ RINGS [PDF]
We construct various examples of Armendariz and related rings by reviewing and extending some results concerning the structure of monoid M. In particular, we give some examples of Armendariz rings related to a monoid.
