Enhanced monopulse radar tracking using fractional Fourier filtering in the presence of interference [PDF]

open access: yes, 2010
Monopulse radars are used to track a target that appears in the look direction beam width. Significant distortion is produced when manmade high power interference (jamming) is introduced to the radar processor through the radar antenna main lobe (main ...

Curcumin Nanoformulations for Dermatological Applications: From Nutraceuticals to Nanocarriers

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Nanotechnology‐based delivery platforms enhance the cutaneous administration of curcumin. Loading free curcumin into polymeric micelles, metal‐based nanoparticles, nanogels/hydrogels, liposomes, polymeric nanoparticles, or nanoemulsions/nanocrystals helps address its low solubility, poor stability and limited skin permeation. As a result, these systems

Estimating DGSE models with long memory dynamics [PDF]

open access: yes
Recent literature clams that key variables such as aggregate productivity and inflation display long memory dynamics. We study the impllications of this high degree of persistence on the estimation of Dynamic Stochastic General Equilibrium (DGSE) models.
