Phytotoxicity and Data Analytics Pipeline for Silver-Coated Cobalt Ferrite Nanoparticles (Ag@CoFe2O4 NPs) in Wheat Plants

This notebook implements an advanced ecotoxicological data analytics pipeline to evaluate the phytotoxicity and multivariate physiological impacts of silver-coated cobalt ferrite nanoparticles (Ag@CoFe2O4 NPs) in wheat plants. Organized into four analytical stages, the workflow h...

Symmetry-Based Simulation of a Dual Inverter Under Different Load Conditions

This paper presents a symmetry-based analysis applied to a dual-inverter system that powers different types of loads. The configuration consists of two three-phase inverters controlled using carrier-based space-vector pulse-width modulation (CBSV-PWM). The study investigates how...

Quantification of Carbon, Water, and Energy Footprints Associated with Refined Cane Sugar Production in Mexico Through Life Cycle Assessment

Integrated life cycle assessments combining carbon, water, and energy footprints are uncommon for cane sugar production in Mexico, particularly in high-productivity regions where aging infrastructure substantially affects environmental performance. This study quantified these thr...

Seropositivity and Antigen-Specific Seroreactivity to Leptospira spp. In Equids from Three Regions of Veracruz, Mexico

Information on Leptospira spp. exposure in Mexican equids remains limited. This cross-sectional study evaluated seropositivity and antigen-specific seroreactivity in 313 apparently healthy equids enrolled by convenience sampling in Los Tuxtlas (n = 119), Sotavento (n = 108), and...

Enabling climate action: A nexus approach for delivering co-benefits across biodiversity, water, food, and health

Climate response options rarely affect biodiversity, water, food, and health in uniform ways. This comparative analysis examines why technically viable response options generate uneven cross-nexus outcomes, and how governance and justice conditions shape whether these outcomes be...

The TOP ‐ GERD Trial: Comparative Efficacy of Tegoprazan Versus Pantoprazole in the Treatment of Erosive Oesophagitis in a Non‐Asian Population

ABSTRACT Background Potassium‐competitive acid blockers provide rapid and sustained acid suppression, but tegoprazan has not been studied in non‐Asian populations. Aim To compare the efficacy and safety of tegoprazan 50 mg once daily with pantoprazole 40 mg once daily for healing...

Beyond comoving volume: horizon flux and matter creation in modified cosmology from the unified first law of thermodynamics

Abstract We explore the derivation of the Friedmann equations from a thermodynamic perspective, applying the unified first law of thermodynamics to the apparent horizon of a flat Friedmann–Lemaître–Robertson–Walker (FLRW) universe. We extend this framework to incorporate gravitat...

Tartrazine-Induced Toxicity Is Attenuated by Naringenin in Wistar Rats: A Biochemical, Histological, and Behavioral Study

Background: Tartrazine (TZ) has been linked to hyperactivity in children, as well as to kidney and liver damage. Furthermore, naringenin (NG) is a flavonoid with antioxidant and anti-inflammatory properties that may mitigate the damage caused by TZ. Methods: Four independent grou...

Sustainable Management of Air-Conditioning Systems Condensate Water Recovery

The global water crisis represents one of humanity’s most pressing challenges, with over 2 billion people lacking access to safely managed drinking water. This study presents the implementation and evaluation of an innovative air-conditioning condensate recovery system at Buildin...

A network-driven antiviral discovery pipeline for emerging RNA viruses: a critical perspective from the Red Mexicana de Desarrollo de Antivirales (RMDA)

INTRODUCTION: RNA viruses impose a disproportionate burden of emerging and reemerging infectious diseases in Latin America, yet antiviral discovery in the region remains fragmented, target-limited, and frequently disconnected from translational pathways. This perspective discusse...

Untargeted Metabolomics of Xylem Sap Exudates in Two Common Bean Genotypes with Contrasting Growth Rates Under Water Deficit During Pod Filling

Background/Objectives: Water deficit during the pod filling stage severely limits the productivity of common beans (Phaseolus vulgaris). Although the effects of water scarcity have been extensively studied in leaves and roots, the contribution of xylem sap to systemic metabolic a...

Analysis of the Mechanical Behavior of Virgin and Virgin-Recycled Polystyrene

General-purpose polystyrene (GPPS) is widely used in packaging and insulation, although its recyclability poses environmental challenges that require circular economy strategies. The objective of this study was to evaluate the mechanical and tribological behavior of virgin GPPS (...

Relationship between body composition, executive functions and self-regulation of eating habits in university students: an analysis with a gender perspective

To evaluate associations between body composition, executive functions, and self-regulation of eating habits, and to explore whether the multivariate pattern of performance differs by gender in university students. The sample included 91 students. Body composition, executive func...

Contrasting eruptive dynamics and hazards of two Holocene andesitic sub-Plinian to Plinian eruptions, Lower and Upper Citlaltépetl, at Pico de Orizaba, Mexico

Abstract Pico de Orizaba (Citlaltépetl) stratovolcano, eastern Mexico, preserves a complex Holocene explosive record, yet the eruptive dynamics, source parameters, styles, and hazard implications of individual eruptive episodes remain poorly constrained. Here, we examine the 9600...

Total Hydrocarbons in Intertidal Interstitial Water of Sandy Beaches of the Central Region of Veracruz

Sandy beaches in the Central Region of Veracruz (CRV) face constant anthropogenic pressure from port and urban activities. This study aimed to evaluate total hydrocarbon (TH) concentrations in the intertidal interstitial water of five beaches in the CRV, analyzing their variabili...

Techno-Spatial and Economic Assessment of Rooftop Versus Land-Based Photovoltaic Deployment in a Biodiversity-Sensitive Region of the Mexican Caribbean

Solar photovoltaic (PV) expansion in fast-growing tropical regions requires engineering-based frameworks that compare deployment pathways in terms of electricity generation, spatial footprint, and economic performance. This study develops a techno-spatial and economic assessment...

Eosinopenia as an Independent Predictor of Complicated Acute Appendicitis: Usefulness in Adults, Not in Children

Background. The role of eosinophils in acute appendicitis (AA) is not well known. The aim of this study is to analyze whether peripheral blood eosinophil concentration can be useful in predicting episodes of complicated AA among pediatric and adult populations.Methods. A retrospe...
