Global Oil and Gas Stocks: Anomalies, Systematic Risks and Mispricing

International Journal of Finance &Economics, EarlyView.
ABSTRACT We analyse anomaly and factor risk premia in the global oil and gas (OG) sector, which plays a central role in the global economy through its importance for energy supply, industrial production, and capital markets. Using firm‐level and portfolio data, we examine whether cross‐sectional return patterns reflect systematic risk compensation or ...

Air Quality Evaluation Using Gaussian Plume Model and GIS at Gas Flaring Region in Kirkuk City, Iraq [PDF]

Pollution
Gas flaring continues as an environmental issue across oil-producing regions since it generates air pollution and climate change conditions. The purpose of the research is to examine, and compare the spatial distribution of deterioration of air quality ...

Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

Spatio‐Temporal Assessment of the Complementarity Between Hydroelectric, Wind and Solar Energy Sources for Northeastern Brazil

International Journal of Climatology, EarlyView.
Using 24 years of climate and hydrological data, this study quantifies the spatiotemporal complementarity among the water availability of the Sobradinho reservoir, wind and solar in Northeastern Brazil. The integration of hierarchical clustering and compromise programming reveals how seasonal variability and reservoir dynamics interact with atmospheric

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Bilateral Breast Gradient Insert Prototype for Strong Diffusion Encoding at 3 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Diffusion MRI has shown promise for breast cancer screening, lesion characterization, and treatment response monitoring without contrast agents, but further translation is constrained by the gradient performance of conventional systems.
