Direct Computation of a Hole-Tone Feedback System at Very Low Mach Numbers

open access: yesJournal of Fluid Science and Technology, 2011
This study is concerned with an investigation into the sound produced when a jet, issued from a circular nozzle or hole in a plate, goes through a similar hole in a second plate.

On the Use of Movement-Based Interaction with Smart Textiles for Emotion Regulation

open access: yesSensors, 2021
Research from psychology has suggested that body movement may directly activate emotional experiences. Movement-based emotion regulation is the most readily available but often underutilized strategy for emotion regulation.

Emerging functions of Pannexin 1 in the eye

open access: yesFrontiers in Cellular Neuroscience, 2014
Pannexin 1 (Panx1) is a high-conductance, voltage-gated channel protein found in vertebrates. It has been shown that Panx1 is widely expressed in many organs and tissues, including sensory systems.

An Interacting Negative Feedback Mechanism in a Coupled Extreme Weather–Humans–Infrastructure System: A Case Study of the 2021 Winter Storm in Texas

open access: yesFrontiers in Physics, 2022
Extreme weather has long been a threat to human life and critical infrastructures. Previous studies have focused on the reliability and vulnerability of single or interdependent infrastructures under extreme weather threats.

Mechanical feedback in seashell growth and form [PDF]

open access: yesANZIAM Journal, 2018
Mollusc seashells grow through the local deposition and calcification of material at the shell opening by a soft and thin organ called the mantle. Through this process, a huge variety of shell structures are formed. Previous models have shown that these structural patterns can largely be understood by examining the mechanical interaction between the ...

Assessing the impact of affective feedback on end-user security awareness [PDF]

open access: yes, 2017
A lack of awareness regarding online security behaviour can leave users and their devices vulnerable to compromise. This paper highlights potential areas where users may fall victim to online attacks, and reviews existing tools developed to raise users ...

Feedback Integrators for Nonholonomic Mechanical Systems [PDF]

open access: yesJournal of Nonlinear Science, 2018
The theory of feedback integrators is extended to handle mechanical systems with nonholonomic constraints with or without symmetry, so as to produce numerical integrators that preserve the nonholonomic constraints as well as other conserved quantities.

Mechanically Contacted Distributed-Feedback Optical Microcavity

open access: yesNanomaterials, 2022
We report a construction of distributed-feedback (DFB) optical microcavities, which is realized through mechanical contact between a high-quality planar thin film of a polymeric semiconductor and a large-area homogeneous nanograting. Using poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3] thiadiazol-4,8-diyl)] (F8BT) as the active medium for the ...

Entropy Injection as a Global Feedback Mechanism [PDF]

open access: yes, 2002
Both preheating of the intergalactic medium and radiative cooling of low entropy gas have been proposed to explain the deviation from self-similarity in the cluster L_x-T_x relation and the observed entropy floor in these systems.

Super-Resolution Image Reconstruction Algorithm Based on Feedback Mechanism [PDF]

open access: yesJisuanji gongcheng, 2022
Although existing super-resolution image reconstruction methods make full use of high-performance deep learning models, they ignore the feedback mechanism that is ubiquitous in the human visual system.This paper proposes a super-resolution image ...
