A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Tension fluctuation analysis of main ropes for 2:1 roping elevator by variations in groove depth of traction machine

Mechanical Engineering Journal
As buildings have become taller in recent years, elevators, which provide vertical transportation within buildings, are becoming larger in capacity and tend to have longer lifting strokes. Generally, the rope-type elevator has multiple main ropes. As the

Integrated PANoptosis Profiling Identifies Immunosuppressive Subtypes and a Prognostic Signature With Functional Validation of MLKL in Glioblastoma

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The prognosis of glioblastoma (GBM) remains highly unfavorable, largely due to high tumor heterogeneity and an immunosuppressive microenvironment. However, the functional role of PANoptosis in this context is poorly understood. Methods Patients were stratified via K‐means clustering. A risk score model was constructed using prognosis‐

Free vibration analysis of elevator rope with vibration suppressors located except for both ends part

Nihon Kikai Gakkai ronbunshu, 2017
Vibration suppressors are used to change the natural frequency of an elevator rope and prevent resonance. The displacement of the parts of the elevator rope at both the ends is small compared to that of the center part of the rope; therefore, it is not ...

A data-driven approach for modifying the rope dynamics model of the flexible hoisting system

Journal of Low Frequency Noise, Vibration and Active Control, 2023
In the flexible hoisting system, past research focused on the physical modeling without considering complex external environmental variables such as guided rails excitation and shaft effect, leading to a significant deviation between the physical model ...
