Comparative Evaluation of R134a and HFO-1234ze Cryogen Spray Cooling Using a Mouse Model With Controllable Epidermal Pigmentation. [PDF]

Lasers Surg Med
ABSTRACT Objectives Cryogen spray cooling (CSC) is critical for protecting the epidermis during laser dermatologic procedures. The widely used cryogen, R134a, has a high global warming potential (GWP), motivating interest in environmentally favorable alternatives such as HFO‐1234ze.

Triggered Ferroelectricity in HfO₂ From Hybrid Phonons and Higher-Order Dynamical Charges. [PDF]

Adv Mater
We combine first‐principles calculations, LGD theory and group theory to demonstrate the mechanism of hybrid‐triggered ferroelectricity in HfO2${\rm HfO}_2$, enabled by trilinear and quadlinear couplings between stable polar and nonpolar modes. HfO2${\rm HfO}_2$ hosts unconventional interplay between structure modes where substantial contribution to ...

Honey formation optimization: HFO

Turkish Journal of Engineering, 2021
In this paper, a new optimization framework, namely Honey Formation Optimization (HFO), is proposed. In contrary to the Artificial Bee Colony Optimization (ABC) variants in literature, the HFO considers food sources consisting of many components and model the honey formation inside bees as a process of mixing the components with their special enzymes ...

Water/Heavy Fuel Oil Emulsion Production, Characterization and Combustion

International Journal of Renewable Energy Development, 2021
In order to produce a water/heavy fuel oil emulsion (W/HFO) with different water contents to cover the daily needs of a fire tube boiler or a water tube boiler, a special homogenizer is designed, constructed and tested.

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.

Scalp HFO rates are higher for larger lesions

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,
