PIV [PDF]

open access: yesACM Transactions on Computer-Human Interaction, 2020
We describe the design and evaluation of PIV, a personalizable and inconspicuous vibrotactile breathing pacer. Given the prevalence and adverse impact of anxiety and anxiety disorders, our goal is to develop a technology that helps people regulate their anxiety through paced breathing.

Pre-Clinical Models in Implant Dentistry: Past, Present, Future

open access: yesBiomedicines, 2021
Biomedical research seeks to generate experimental results for translation to clinical settings. In order to improve the transition from bench to bedside, researchers must draw justifiable conclusions based on data from an appropriate model.

Drag Reduction Performance of Triangular (V-groove) Riblets with Different Adjacent Height Ratios [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
Surface structure is used to interfere with the turbulent boundary layer in the groove drag reduction, which is important to the endurance and stability of high-speed and ultrahigh-speed aircraft.

Unsupervised learning on particle image velocimetry with embedded cross‐correlation and divergence‐free constraint

open access: yesIET Cyber-systems and Robotics, 2022
Particle image velocimetry (PIV) is an essential method in experimental fluid dynamics. In recent years, the development of deep learning‐based methods has inspired new approaches to tackle the PIV problem, which considerably improves the accuracy of PIV.

Epidemiology and clinical severity of the serotypes of human parainfluenza virus in children with acute respiratory infection

open access: yesVirology Journal, 2023
Background Acute respiratory infections (ARI) are a threat to human health and survival, resulting in many paediatric hospitalisations. However, the epidemiological and clinical severity characteristics of the human parainfluenza virus (PIV), one of the ...

High pre-chemoradiotherapy pan-immune-inflammation value levels predict worse outcomes in patients with stage IIIB/C non-small-cell lung cancer

open access: yesDiscover Oncology, 2023
Background and objectives We explored the prognostic usefulness of the pan-immune-inflammation value (PIV) in patients with stage IIIB/C non-small-cell lung cancer (NSCLC) who underwent concurrent chemoradiotherapy (CCRT).

Experimental Study on a Generic Side-View Mirror with Slotted Cylindrical Foot [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
A simple model consisting of a mirror-housing and its cylindrical foot is applied to represent the automobile side-view mirror that causes unwanted aerodynamic noise and wind drag during high-speed driving. An additional slot is made on the solid foot to

Experimental Study of the Particles Influence on the Pyramid Wake within the Turbulent Boundary Layer [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
Particle imaging velocimetry (PIV) was used to study the near-field variation of a pyramid rough element in clear water and a liquid–solid boundary layer (thickness: 60 mm).

Securing All intraVenous devices Effectively in hospitalised patients—the SAVE trial: study protocol for a multicentre randomised controlled trial [PDF]

open access: yes, 2015
Introduction: Over 70% of all hospital admissions have a peripheral intravenous device (PIV) inserted; however, the failure rate of PIVs is unacceptably high, with up to 69% of these devices failing before treatment is complete.
