Comparative Analysis of the Performances of a Nonlinear Observer and Nonlinear Kalman Filters in the Presence of Non‐Gaussian Disturbances

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 7, Page 3896-3913, 10 May 2026.
ABSTRACT This paper focuses on state estimation for a fairly general class of systems, involving nonlinear functions and disturbances in both the process dynamics and output equations. A nonlinear observer that satisfies a H∞$$ {\boldsymbol{H}}_{\boldsymbol{\infty}} $$ disturbance attenuation constraint in addition to providing asymptotic stability in ...

Disrupted CO Migration and Reversed Activity in CuAg Spatiotemporal Tandem Catalysts for C2+ Production

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Rational catalyst architecture is essential for driving the electrochemical CO2 reduction toward multi‐carbon (C2+) products; however, many previously reported strategies rely on intricate structural designs that hinder large‐scale implementation.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, Volume 309, Issue 5, Page 1299-1312, May 2026.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Shock‐Assisted Flow Control System in Convergent‐Divergent Nozzle: A Numerical Study on Unconventional Protuberance With Different Geometry

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.
