No Degree, No Lab, No Borders: An Independent Researcher's Journey From Yemen to Global Science
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract I grew up in Yemen with a dream to study space, but my country had no astronomy programs, no universities for astrophysics, and soon, no stable peace. This Perspective is a personal and systemic account of how I pursued planetary science from a conflict zone—with no smartphone, no home internet, no supervisor, and no institutional backing.

Nightside Auroral Arcs Near the Electron Isotropy Boundary: TRACERS–THEMIS–MetOp Observations
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract Particle precipitation is the ultimate driver of aurorae. Monoenergetic (∼keV) electrons accelerated above the ionosphere produce discrete auroral forms and are associated with field‐aligned currents that govern magnetosphere–ionosphere (MI) coupling.

Novel Bernstein‐Kantorovich Type Operators
Mathematical Methods in the Applied Sciences, Volume 49, Issue 16, Page 17069-17095, 15 November 2026.ABSTRACT In this paper, we introduce a novel class of Bernstein‐Kantorovich operators, denoted as K β n , θ $$ {K}_{\beta}^{n,\theta } $$ , parameterized by 0 < β < 1 $$ 0<\beta <1 $$ and θ > 0 $$ \theta >0 $$ . We first derive a recurrence formula that facilitates the computation of moments and central moments and provide explicit expressions for K β ...

Advanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...
