Finite Element Analysis of Upper Airway in Ansa Cervicalis Stimulation for Obstructive Sleep Apnea

open access: yesThe Laryngoscope, EarlyView.
We developed a subject‐specific FE model to investigate how ACS stabilizes the upper airway in OSA. Simulations demonstrate that caudal traction applied through the hyolaryngeal complex produces coordinated multilevel airway stabilization, with pronounced effects at the retropalatal and retro‐epiglottic regions under physiologic loading.

The Musculoskeletal Consequences of Mouth Breathing in Adults: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
Chronic mouth breathing can have a negative impact on posture, cause temporomandibular joint dysfunction (TMD), reduced masticatory muscle activity and efficiency, and suprahyoid muscle overuse. Postural changes include a head forward posture and increased lumbar lordosis.

A Comparative Numerical Simulation of Fracture Behavior: Standard Part vs. Topologically Optimized

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT The design of damage‐tolerant structures is a cornerstone of safety and reliability in the modern automotive industry. While topology optimization is widely recognized for its efficiency in mass reduction for stiffness‐driven problems, its direct impact on complex failure mechanisms such as fracture propagation remains a less explored, yet ...

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...
