Spatial Dynamics of a Radially Polarized Terahertz Laser Beam with a Phase Singularity
East European Journal of PhysicsAnalytical expressions are obtained that describe the nonparaxial diffraction in free space of the TM01 mode with radial polarization of the field of the dielectric waveguide resonator of a terahertz laser during its interaction with a spiral phase plate

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Plate dynamics, mantle structure and tectonic evolution of the Caribbean region [PDF]
, 2013 The northeastern Caribbean exhibits high deformation and is fragmented by several faults into smaller tectonic blocks. One of these faults was the site of the catastrophic 12th of January 2010 earthquake. In this thesis I aim to constrain the main forces

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Annular plate inspection using guided wave tomography
, 2013 Corrosion is one of the industries major issues regarding the integrity of assets. In case of storage tanks, corrosion of the annular plate is a potential risk, which ultimately can lead to catastrophic failure of such a tank.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

The sound pressure of an individual mode of a clamped-free annular plate
Archives of Acoustics, 2002 The paper presents some theoretical results together with the corresponding numerical results of the directivity pattern of sound radiation of the clamped-free, free-clamped, and fully clamped annular plates. The results obtained are valid
