A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk
A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...

On the convective excitation of torsional oscillations in rotating systems
An asymptotic theory is presented to describe the possible mechanism for the excitation and maintenance of torsional oscillations in rotating convective stars and planets. It is demonstrated analytically that the torsional oscillations can be excited and

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Opsoclonus in Pediatric Patients: Differential Diagnosis and a Practical Approach to Evaluation
ABSTRACT Opsoclonus is an ocular dyskinesia characterized by involuntary, arrhythmic, multidirectional saccades. In pediatrics, opsoclonus is most commonly attributed to the rare neuroinflammatory disorder opsoclonus‐myoclonus‐ataxia syndrome (OMAS), typically considered a paraneoplastic syndrome associated with neural crest tumors. However, opsoclonus

THE USE OF GRAPHS AND AUTOMATA TO THE CALCULATION OF DISCRETE AND CONTINUOUS BEAMS VIBRATIONS
The topological models for longitudinal and torsional oscillations of rod structures with various concentrated inclusions in distributed mass, stiffness of elastic medium and rod stiffness are done.

ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Multiple periodic solutions to a suspension bridge O.D.E.
We present an ordinary differential equation which models the torsional motion of a horizontal cross section of a suspension bridge. We use Leray-Schauder degree theory to prove that the undamped equation has multiple periodic weak solutions.
