Research on Nonlinear Dynamics Modeling and Simulation of Harmonic Gear Drive
Jixie chuandong, 2021 Due to the particularity of the structure，the hysteretic stiffness and dynamic friction belong to the inherent properties of harmonic gear drive. Traditional models consider the stiffness as a fixed stiffness or segmented stiffness model，and the friction

Control of electron-hole pair generation by biharmonic voltage drive of a quantum point contact
, 2012 A time-dependent electromagnetic field creates electron-hole excitations in a Fermi sea at low temperature. We show that the electron-hole pairs can be generated in a controlled way using harmonic and biharmonic time-dependent voltages applied to a ...

Photonic microwave harmonic generator driven by an optoelectronic ring oscillator [PDF]
, 2007 We describe a new architecture to generate microwave signals by optical means. Our system combines the advantages of two techniques: frequency multipliers and loop oscillators.

Digital twins to accelerate target identification and drug development for immune‐mediated disorders
FEBS Open Bio, EarlyView.Digital twins integrate patient‐derived molecular and clinical data into personalised computational models that simulate disease mechanisms. They enable rapid identification and validation of therapeutic targets, prediction of drug responses, and prioritisation of candidate interventions.

Crack Propagation Simulation and Meshing Stiffness Analysis of Disposable Harmonic Gears
Jixie chuandong, 2023 The mechanical equipment in aerospace field that will not be reused after being used once is called disposable machinery. The failure of the flexible wheel is the most important factor affecting the performance of the disposable harmonic reducer.

Aging and Cancer, EarlyView.This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Dystonia is one of the most common movement disorders, with variants in multiple genes identified as causative. However, an understanding of which developmental stages, brain regions, and cell types are most relevant is crucial for developing relevant disease models and therapeutics.
