Performance analysis of modeling scale on multiband oscillations in grid-connected wind farm
Frontiers in Energy Research, 2023 Grid-connected permanent magnet synchronous generator (PMSG) wind farms may be susceptible to oscillation when connected to weak grids. This paper explores the root causes of the oscillations from two perspectives: the model and the oscillation frequency

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Boundary‐Dependent Sleep–Wake Dysregulation in Idiopathic Hypersomnia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble
, 2009 The need for better understanding of the low-frequency unsteadiness observed in shock wave/turbulent boundary layer interactions has been driving research in this area for several decades.

LOW-FREQUENCY SWASH OSCILLATION
Doboku Gakkai Ronbunshu, 1993 Swash oscillation の周期は入射波のそれに比べて長くなることが知られている. こうした swash oscillation の長周期化を水理実験および有限振幅長波理論に基づく数値モデルにより検討し, 長周期波のほかに, swash zone での寄せ波と引き波の時系列に依存する追い付き・合体・吸収といった相互干渉によっても長周期の swash oscillation が形成されることを示した.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
