Scalp HFO rates are higher for larger lesions [PDF]

Epilepsia Open, 2022
High‐frequency oscillations (HFO) in scalp EEG are a new and promising noninvasive epilepsy biomarker, providing added prognostic value, particularly in pediatric lesional epilepsy. However, it is unclear if lesion characteristics, such as lesion volume,

Investigation on Miscibility of Lubricant and Mixed Refrigerant HFO-1234yf/HFO-1216

Applied Sciences
The HFO-1234yf/HFO-1216 mixture is a promising alternative refrigerant to HFC-134a due to its excellent environmental performance. Experimental investigation of the phase equilibrium between the mixture and lubricating oils is essential for screening suitable oils in practical refrigeration systems.

Thermal Properties Model for the New Refrigerant HFO-1234yf

Zhileng xuebao, 2012
Based on Peng-Robinson general state equation, combined with group contribution principle and a polynomial method, the thermal state model of the new LGWP refrigerant HFO-1234yf was established and validated with required accuracy.

Time-frequency characteristics of scalp high-frequency oscillations provide complementary biomarkers in infantile epileptic spasms syndrome. [PDF]

Exp Physiol
Abstract Infantile epileptic spasms syndrome (IESS) is characterized by epileptic spasms (ES) in infants and hypsarrhythmia on EEG. High‐frequency oscillations (HFOs), defined as oscillatory events at >80 Hz, reflect rapid spatiotemporal dynamics of cortical activity and might serve as novel biomarkers for epilepsy.

High-Flow Nasal Oxygen in Early Home Pulmonary Rehabilitation for Exertional Hypoxaemia: A Pilot Randomised Feasibility Trial. [PDF]

Respirology
This pilot randomised feasibility trial evaluated the feasibility and acceptability of early, intensive home‐based pulmonary rehabilitation (PR) and high‐flow nasal oxygen (HFO) during exercise in patients with exertional hypoxaemia post‐hospitalisation. Early home‐based PR was feasible and safe.

Scalp high‐frequency oscillations differentiate neonates with seizures from healthy neonates

Epilepsia Open, 2023
Objective We aimed to investigate (1) whether an automated detector can capture scalp high‐frequency oscillations (HFO) in neonates and (2) whether scalp HFO rates can differentiate neonates with seizures from healthy neonates.

Influence of HFO refrigerants on the viscoelastic behavior of elastomers

, 2022
S.421-428The hydrofluoroolefines (HFO) have been introduced within the last years as new generation of refrigerants having a significantly lower Global Warming Potential. Compared to the state-of-the-art fluids within the class of hydrofluorocarbons (HFC)

Scalp HFO rates decrease after successful epilepsy surgery and are not impacted by the skull defect resulting from craniotomy

Scientific Reports, 2022
Epilepsy surgery can achieve seizure freedom in selected pediatric candidates, but reliable postsurgical predictors of seizure freedom are missing. High frequency oscillations (HFO) in scalp EEG are a new and promising biomarker of treatment response ...
