Time-crystalline phases and period-doubling oscillations in one-dimensional Floquet topological insulators

Physical Review Research, 2020
In this work, we report a ubiquitous presence of topological Floquet time crystal (TFTC) in one-dimensional periodically driven systems. The rigidity and realization of spontaneous discrete time-translation symmetry (DTS) breaking in our TFTC model ...

Observation of Period-Doubling Bloch Oscillations

Physical Review Letters
Bloch oscillations refer to the periodic oscillation of a wavepacket in a lattice under a constant force. Typically, the oscillation has a fundamental period that corresponds to the wavepacket traversing the first Brillouin zone once. Here we demonstrate, both theoretically and experimentally, the optical Bloch oscillations where the wavepacket must ...

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

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 ...

Period doubling of multiple dissipative-soliton-resonance pulses in a fibre laser [PDF]

, 2020
We report on the experimental observation of the period doubling of multiple dissipative-soliton-resonance (DSR) pulses in an all-normal-dispersion fibre laser, based on a nonlinear amplifying loop mirror.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

A New Feigenbaum-Like Chaotic 3D System

Discrete Dynamics in Nature and Society, 2014
Based on Sprott N system, a new three-dimensional autonomous system is reported. It is demonstrated to be chaotic in the sense of having positive largest Lyapunov exponent and fractional dimension. To further understand the complex dynamics of the system,

Period Doubling in Kepler RR Lyrae Stars

, 2013
The origin of the conspicuous amplitude and phase modulation of the RR Lyrae pulsation---known as the Blazhko effect---is still a mystery more than 100 years since its discovery.

Effects of pre-stretch, compressibility and material constitution on the period-doubling secondary bifurcation of a film/substrate bilayer [PDF]

, 2019
We refine a previously proposed semi-analytical method, and use it to study the effects of pre-stretch, compressibility and material constitution on the period-doubling secondary bifurcation of a uni-axially compressed film/substrate bilayer structure ...

Sex Representation in US Stroke Clinical Trials: A Decade of Trends and Challenges

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke remains a major cause of disability and mortality in the US, with significant sex‐based disparities, and females remain underrepresented in stroke clinical trials. We aimed to examine sex representation in US‐based stroke clinical trials, identify trial characteristics associated with higher female enrollment (≥ 50%), and ...

Bifurcation Mechanism and Stabilization of V²C Controlled Buck Converter

IEEE Access, 2019
The V2C controlled buck converter by constant-frequency pulse-width modulation in continuous conduction mode gives rise to a great variety of instability behaviors, depending on the circuit parameter values.
