Design and evaluation of a 3 million DN series-hybrid thrust bearing [PDF]
The bearing, consisting of a 150-mm ball bearing and a centrifugally actuated, conical, fluid-film bearing, was fatigue tested. Test conditions were representative of a mainshaft ball bearing in a gas turbine engine operating at maximum thrust load to ...

Brain and Behavior, Volume 16, Issue 5, May 2026.ABSTRACT Purpose This narrative review aims to explore how incorporating mechanical and thermal dimensions can complement and extend the classical Hodgkin‐Huxley (HH) model to enrich the understanding of headache and pain pathophysiology. Method This review examines the integration of three distinct concepts with the HH model.

Multiple Longitudinal Tracts in the Cephalopod Arm Sensorimotor System
Journal of Comparative Neurology, Volume 534, Issue 5, May 2026.Octopuses have a rich behavioral repertoire, coordinating complex movements along the length of an arm. The neural circuits controlling these behaviors are poorly understood. We employ tract‐tracing to investigate longitudinal tracts in the octopus arm.

Effects of vibration and shock on the performance of gas-bearing space-power Brayton cycle turbomachinery. Part 4: Suppression of rotor-bearing system vibrations through flexible bearing support damping [PDF]
A bearing damper, operating on the support flexure of a pivoted pad in a tilting-pad type gas-lubricated journal bearing, has been designed, built, and tested under externally-applied random vibrations. The NASA Brayton Rotating Unit (BRU), a 36,000 rpm,

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Evaluation of a series hybird thrust bearing at DN values to three million. 1: Analysis and design [PDF]
The analysis and design are presented of a hybrid bearing consisting of a 150-mm ball bearing and a centrifugally actuated, conical, fluid film bearing fitting an envelope with an outer radius of 86.4 mm (3.4 in.) and an inner radius of 71 mm (2.8 in ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Evaluation of a hybrid hydrostatic bearing for cryogenic turbopump application [PDF]
A hybrid hydrostatic bearing was designed to operate in liquid hydrogen at speeds to 80,000 rpm and radial loads to 440 n (100 lbf). The bearing assembly consisted of a pair of 20-mm angular-contact ball bearings encased in a journal, which was in turn ...

Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.
