Music Voice Modification Method for Stable Timbre [PDF]

open access: yesJisuanji gongcheng, 2018
Traditional methods of speech modulation fail to consider the tone and the edge tone,which affect the sound quality and cause distortion.In order to solve this problem,this paper proposes an improved modulation method based on linear prediction.According

Quantized Excitation Spectrum of the Classical Harmonic Oscillator in Zero-Point Radiation [PDF]

open access: yes, 2012
We report that upon excitation by a single pulse, the classical harmonic oscillator immersed in classical electromagnetic zero-point radiation, as described by random electrodynamics, exhibits a quantized excitation spectrum in agreement to that of the ...

Lattice oscillator model, scattering theory and a many-body problem

open access: yes, 2011
We propose a model for the quantum harmonic oscillator on a discrete lattice which can be written in supersymmetric form, in contrast with the more direct discretization of the harmonic oscillator.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

A corner smoothing algorithm using Trajectory Pattern Method (TPM) for high-speed and high-quality machining

open access: yesAdvances in Mechanical Engineering, 2021
In micro-line segments machining, transition curves with high harmonic components are more prone to causing vibration issues in the feed drive system, which affects machining efficiency and quality severely.

Disentangling the effects of phonation and articulation: Hemispheric asymmetries in the auditory N1m response of the human brain [PDF]

open access: yes, 2005
BACKGROUND: The cortical activity underlying the perception of vowel identity has typically been addressed by manipulating the first and second formant frequency (F1 & F2) of the speech stimuli.

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia

open access: yesAnnals 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.

Quadrupole-scissors modes and nonlinear mode coupling in trapped two-component Bose-Einstein condensates

open access: yes, 2003
We theoretically investigate quadrupolar collective excitations in two-component Bose-Einstein condensates and their nonlinear dynamics associated with harmonic generation and mode coupling.

Shared Genetic Effects and Antagonistic Pleiotropy Between Multiple Sclerosis and Common Cancers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epidemiologic studies have reported inconsistent altered cancer risk in individuals with multiple sclerosis (MS). Factors such as immune dysregulation, comorbidities, and disease‐modifying therapies may contribute to this variability.
