Betatron oscillations in a free electron laser [PDF]

open access: yes, 1987
A dispersion relation is used to study the effect of betatron oscillations on the gain of a guided mode in a free electron laser operating in the high-gain regime before saturation.

Finite element reduced order models for nonlinear vibrations of piezoelectric layered beams with applications to NEMS [PDF]

open access: yes, 2012
This article presents a finite element reduced order model for the nonlinear vibrations of piezoelectric layered beams with application to NEMS. In this model, the geometrical nonlinearities are taken into account through a von Kármán nonlinear strain ...

Liquid vibration modeling in prismatic tanks with quarter baffles

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2019
Free vibrations of liquid in a rigid prismatic tank with vertical cross partitions are considered. These partitions divide the tank into four compartments.

Free oscillation oscillator with sinusoidal power characteristic

open access: yesBulletin of the National Technical University «KhPI» Series: Dynamics and Strength of Machines, 2017
Рассмотрены нелинейные колебания, вызванные или начальным отклонением осциллятора от положения равновесия или данной ему в этом положении начальной скоростью. Предполагается, что восстанавливающая сила пропорциональна синусу перемещения колебательной системы. Предусмотрено два варианта синуса: тригонометрический и гиперболический.

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Two-to-one resonant multi-modal dynamics of horizontal/inclined cables. Part I : theoretical formulation and model validation

open access: yes, 2007
This paper is first of the two papers dealingwith analytical investigation of resonant multimodal dynamics due to 2:1 internal resonances in the finite-amplitude free vibrations of horizontal/inclined cables. Part I deals with theoretical formulation and

Suppression of amplitude dependent closest tune approach and its behavior under forced oscillations

open access: yesPhysical Review Accelerators and Beams, 2019
An amplitude dependent closest tune approach (ADeCTA) was first observed in the LHC in 2012. This potentially harmful effect can be generated by linear coupling in conjunction with octupoles.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.
