Alpha - Skew Pi - Armendariz Rings

, 2018
In this article we introduce a new concept called Alpha-skew Pi-Armendariz rings (Alpha - S Pi - AR)as a generalization of the notion of Alpha-skew Armendariz rings.Another important goal behind studying this class of rings is to employ it in order to ...

Methane and Ethane Emission Rates, Intensities, and Trends: Aircraft Mass Balance Insights Over the Denver‐Julesburg Basin, Fall 2021

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Despite a 2.1‐fold increase in oil and gas (O&G) production from 2012 to 2021 in the Wattenberg Field (WF) area of the Denver‐Julesburg Basin (DJB), total methane (CH4) emissions have remained unchanged within measurement uncertainties (26.0 ± 6.8 t/hr in 2012, 24.0 ± 5 t/hr in 2015, and 21.4 ± 5.7 t/hr in 2021), while ethane (C2H6) emissions ...

Democratic Decline and Return Migration: What Motivates Highly‐Skilled Voluntary Return to Post‐2016 Turkey?

International Migration, Volume 64, Issue 2, April 2026.
ABSTRACT Migration scholars often present democratic decline as an emigration driver. This effect is more pronounced among highly‐skilled citizens who have the resources and capability to settle abroad. Yet, not much attention has been paid to why highly‐skilled emigrants would opt to return to their autocratizing countries, even if they are concerned ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells

Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
ABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

Assessing Age‐Specific Variability in Microplastic Intake Through Seafood Consumption: A Case Study in Central Java, Indonesia

Journal of Food Science, Volume 91, Issue 3, March 2026.
ABSTRACT Microplastics (MPs) are frequently detected in seafood. However, the extent to which seafood consumption contributes to MP intake remains uncertain. Previous studies on MP intake in humans did not consider interindividual variability in exposure.

Prevalence of Adverse Events in Mexico Using the Institute for Healthcare Improvement—Global Trigger Tool Method: A Retrospective Study

Journal of Evaluation in Clinical Practice, Volume 32, Issue 2, March 2026.
ABSTRACT Rationale Globally, adverse events (AEs) are a major contributor to mortality, often arising from healthcare management rather than patients' underlying conditions. Aims and Objectives This study aimed to estimate the prevalence of AEs in three different hospitals in central‐north Mexico using the Institute for Healthcare Improvement Global ...

Nutrient Peak Shifts in the Arctic: Implications for Migratory Herbivores Under Climate Change

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim Quantifying how the timing and spatial variability of Arctic vegetation nutrient peaks are projected to shift under climate change, and assessing potential consequences for migratory herbivores that rely on seasonal synchrony with peak plant quality. Location Circumpolar Arctic, with emphasis on tundra regions.

Update and Comparative Analysis of Food Environment Policies in Mexico: Implementation of the Healthy Food Environment Policy Index in 2016 and 2024

Obesity Reviews, Volume 27, Issue 1, Page 1-15, January 2026.
ABSTRACT Introduction Mexico faces a public health crisis due to the rising prevalence of obesity and noncommunicable diseases, primarily driven by unhealthy food environments. Objective To conduct a second implementation of the Food Environment Policy Index in Mexico to assess policy implementation levels related to healthy food environments and to ...

Idempotent McCoy Rings and Their Properties

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper introduces idempotent McCoy rings, extending McCoy rings by incorporating idempotent elements, and explores their key properties. We provide examples and a counterexample showing that not every idempotent McCoy ring is McCoy. Our results show that if B is a Boolean ring, then the upper triangular matrix ring TnB is idempotent McCoy, but this
