Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti‐Inflammatory and Anti‐Ulcer Effects

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e

The Astronomical Journal
Planets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

Capacitated Vehicle Routing Problem with a Zone Tariff

Networks, Volume 87, Issue 2, Page 210-227, March 2026.
ABSTRACT High demand and volume fluctuations, constrained transportation capacity, and weak network effects compel retailers to rely on external logistic service providers (LSPs) instead of operating their own transportation fleet. This outsourcing process requires retailers to propose tours to LSPs that then carry out the store deliveries.

Seismology of Giant Planets: General Overview and Results from the Kepler K2 Observations of Neptune

EPJ Web of Conferences, 2017
For this invited contribution, I was asked to give an overview about the application of helio and aster-oseismic techniques to study the interior of giant planets, and to specifically present the recent observations of Neptune by Kepler K2.

Did Saturn's rings form during the Late Heavy Bombardment ?

, 2008
The origin of Saturn\' s massive ring system is still unknown. Two popular scenarios - the tidal splitting of passing comets and the collisional destruction of a satellite - rely on a high cometary flux in the past.

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.
