Evaluation of Head Posture in Wheelchair‐Bound Individuals and Its Relation to Malocclusion: A Proof‐of‐Concept Study

Orthodontics &Craniofacial Research, Volume 29, Issue 3, Page 569-575, June 2026.
ABSTRACT Background Malocclusions are significantly more prevalent among individuals with physical and mental disabilities. Head posture, particularly in wheelchair‐bound individuals, may play a role in craniofacial growth and occlusal development, but its specific impact remains poorly understood. Objective To evaluate head posture in wheelchair‐bound

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

International 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 ...

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

The 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),

Reviewing and benchmarking ecological modelling practices in the context of land use

Ecography, Volume 2026, Issue 5, May 2026.
Despite habitat loss and degradation are the primary drivers of biodiversity loss, different conclusions have been drawn about the importance of land‐use or land‐cover (LULC) change for biodiversity. Differences may be due to the difficulty of framing a coherent model design to assess LULC effects.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, Volume 2026, Issue 5, May 2026.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...
