Long non‐coding RNAs as therapeutic targets in head and neck squamous cell carcinoma and clinical application

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Low-frequency acoustic isolation performance of Helmholtz cavity acoustic metamaterials with bilateral single openings

open access: yesAIP Advances
In this study, we designed a single-opening Helmholtz chamber type acoustic metamaterial with two sides. The complexity of the open channel results in the material having a low frequency of the first sound insulation peak and excellent sound insulation ...

Active Noise Control Portable Device Design [PDF]

open access: yesarXiv, 2023
While our world is filled with its own natural sounds that we can't resist enjoying, it is also chock-full of other sounds that can be irritating, this is noise. Noise not only influences the working efficiency but also the human's health. The problem of reducing noise is one of great importance and great difficulty.

Tunable photo-responsive elastic metamaterials

open access: yesNature Communications, 2020
Here, the authors present a light-responsive elastic metamaterial whose transmission spectrum can be tuned by light stimuli. More specifically, we demonstrate that an appropriate laser illumination is effective in reversibly widening an existing ...

Stable and controllable noise [PDF]

open access: yesGraphical Models, 2008
We introduce a stable noise function with controllable properties. The well-known Perlin noise function is generated by interpolation of a pre-defined random number table. This table must be modified if user-defined constraints are to be satisfied, but modification can destroy the stability of the table. We integrate statistical tools for measuring the

Active noise control for high frequencies [PDF]

open access: yes, 2006
There are many applications that can benefit from Active Noise Control (ANC) such as in aircraft cabins and air conditioning ducts, i.e. in situations where technology interferes with human hearing in a harmful way or disrupts communication.

Road traffic noise and registry based use of sleep medication

open access: yesEnvironmental Health, 2017
Background Road traffic noise has been associated with adverse health effects including sleep disturbances. Use of sleep medication as an indicator of sleeping problems has rarely been explored in studies of the effects of traffic noise.

Trapped Modes and Negative Refraction in a Locally Resonant Metamaterial: Transient Insights into Manufacturing Bounds for Ultrasonic Applications

open access: yesApplied Sciences, 2021
The transient scattering of in-plane elastic waves from a finite-sized periodic structure, comprising a regular grid of Swiss-cross holes arranged according to a square lattice, is considered.

On Stochastic Model Predictive Control with Bounded Control Inputs

open access: yes, 2009
This paper is concerned with the problem of Model Predictive Control and Rolling Horizon Control of discrete-time systems subject to possibly unbounded random noise inputs, while satisfying hard bounds on the control inputs.
