Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Inflammatory and neurodegenerative serum protein biomarkers increase sensitivity to detect clinical and radiographic disease activity in multiple sclerosis

Nature Communications
The multifaceted nature of multiple sclerosis requires quantitative biomarkers that can provide insights related to diverse physiological pathways. To this end, proteomic analysis of deeply-phenotyped serum samples, biological pathway modeling, and ...

Spike–fast activity interplay: A gateway to seizure

Epilepsia, EarlyView.
Abstract Objective The transition from interictal discharges to ictal high‐frequency activity (HFA) remains poorly understood. We investigated whether spike‐associated high‐frequency oscillations (Sp‐HFOs) during interictal and preictal periods contribute to the emergence of ictal HFA.

EXPERIMENTAL STUDIES OF NOISE AND VIBRATION IN HYDROELECTROPULSE PRESS WORKING AREA

Advanced Engineering Research, 2013
The experiments supporting theoretical conclusions on the process regularities of the vibration excitation and noise generation are considered. As part of the study, part blanks, such as thin plates and of a complex profile, were machined on the presses ...

The wave equation for stiff strings and piano tuning [PDF]

, 2017
We study the wave equation for a string with stiffness. We solve the equation and provide a uniqueness theorem with suitable boundary conditions. For a pinned string we compute the spectrum, which is slightly inharmonic.

Benefits of using immersive virtual reality in haptic dental simulation for endodontic access cavity training: A comparative crossover study

International Endodontic Journal, EarlyView.
Abstract Introduction The use of haptic virtual reality simulators in preclinical dental education is evolving rapidly. However, the application of immersive haptic simulations for specific dental procedures, such as access cavity preparation, has not been extensively explored.

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

Journal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Father Trait Anger and Exposure to Infant Cry: Effects on Emotion, Appraisals of Infants, and Cognitive Performance

Journal of Personality, EarlyView.
ABSTRACT Objective Trait anger can impact emotional states, appraisals of others, and cognition. The study aim was to assess in fathers whether these associations are exacerbated by infant crying. Method Three hundred sixty‐eight fathers were randomly assigned to infant cry, infant babble, or a non‐infant‐related control while completing assessments of

Souvenir.

EspacesTemps.net, 2007
Les vide-greniers sont des théâtres d’objets que j’affectionne. Le dimanche, au cœur des villages, les gens se rassemblent sur ces marchés où les objets s’animent.
