Tuning optical response and wettability of aluminum surfaces via polarization-controlled femtosecond laser texturing

Femtosecond laser texturing offers a contactless route to tailor the optical and wetting properties of metallic surfaces. Here, we investigate the effect of laser polarization on commercial mirror-finished Al 5005-H34 by comparing linear and circular polarization under matched fl...

Polarization dynamics of an NPR-based Q-switched mode-locked twisted fiber ring laser

In this work, we study the passive mode-locked and Q-switched mode-locked (QSML) operations of an erbium-doped fiber ring laser with twisted fiber in the cavity. Using twisted fiber together with precisely adjusted wave retarders, this configuration allows very tight polarization...

Mechanisms of Cyclonic Meander Formation in the Western Yucatan Channel

Cyclonic meanders in the western Yucatan Channel generate intense frontal conditions associated with strong isopycnal uplift, enhanced vertical shear, and local transformation of Caribbean waters into Yucatan Gulf Common Water. Observational composites further show that strong me...

Main covariability patterns between the Loop Current and the flow through the Yucatan Channel from altimetry and sustained moored observations

The Loop Current (\textbf{LC}) dominates circulation in the Gulf of Mexico, yet how its surface structure relates to Yucatan Channel flow remains incompletely understood. We apply maximum covariance analysis to altimetry-derived geostrophic speed over the LC domain and Canek velo...

Quantum Theoretical, Chemo-Computational, and Comparative Molecular Coupling Studies of Two Enantiomeric Naphthoquinones, Alkannin and Shikonin, and Their Corresponding Indole Derivatives

The use of computational tools has become widespread in drug discovery as an effective approach to guide the development of new therapeutic agents, including potential cancer drugs. In addition, plant-derived secondary metabolites have attracted considerable interest as a valuabl...

Using the Vaquita's Acoustic Behavior to Strengthen Priority Conservation Areas

ABSTRACT The vaquita ( Phocoena sinus ) is an endemic porpoise restricted to the upper Gulf of California, Mexico, with a total range of 4048 km 2 . Using expert elicitation, the number of vaquitas detected in and near the Zero Tolerance Area—a 288 km 2 area within the Vaquita Re...

On the degeneracy of solutions from stellar spectropolarimetric data

Abstract In this work we investigate the inversion accuracy of stellar magnetic fields through the analysis of spectropolarimetric data. We performed several noise-free tests to untangle the impact among the atmospheric and magnetic parameters in the data analysis. Using a single...

Palynomorph assemblages and geochemical indicators of Neogene ocean changes in the Eastern Equatorial Pacific: Insights from DSDP Site 568

DSDP Site 568, off the west coast of Guatemala, was chosen to fill the palynological data gap in the Eastern Equatorial Pacific (EEP) region and improve tropical-to-subtropical regional paleoclimatic models of the Northern Hemisphere. This study analyses palynological assemblages...

CMIP6 Historical Evaluation and Future Changes of Climate Extreme Indices at Regional Scale From the US ‐Mexico Border Region to Central America

ABSTRACT This study evaluates seven climate extreme indices (CEIs) of precipitation and temperature and assesses their potential changes in 15 regions of the CORDEX‐CAM domain (from the southwestern United States to Central America) for different periods: historical (1981–2010),...
