Freezing on a sphere [PDF]

open access: yesNature, 2018
The best understood crystal ordering transition is that of two-dimensional freezing, which proceeds by the rapid eradication of lattice defects as the temperature is lowered below a critical threshold.

General freeze-in and freeze-out [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We use the framework of relativistic and non-relativistic conformal field theories (CFT) to derive general results relevant for the production of weakly coupled and strongly coupled dark sectors through thermal interactions.

Hydrophobization of the surface of mineral forms during cryogenic treatment of highly clayey sands [PDF]

open access: yesE3S Web of Conferences, 2020
The results of experiments in a laboratory flotation device for assessing the effect of cryogenic treatment on the surface properties of natural highly dispersed mineral mixtures, such are high-clay sands, are presented.

Freezing-induced wetting transitions on superhydrophobic surfaces

open access: yesNature Physics, 2023
Icephobic surfaces are helpful for increasing safety and sustainability in engineering applications. A study of the behaviour of supercooled droplets freezing on superhydrophobic surfaces now provides insights into ice-repellency mechanisms.

Discriminating Sleep From Freezing With Cortical Spindle Oscillations

open access: yesFrontiers in Neural Circuits, 2022
In-vivo longitudinal recordings require reliable means to automatically discriminate between distinct behavioral states, in particular between awake and sleep epochs.

Numerical simulation on the freezing of deposited or impinged water droplets on a cold surface

open access: yesJournal of Thermal Science and Technology, 2021
The freezing of water droplets deposited or impinged on cold surfaces causes many problems in traffic lights, power transmission wires and heat exchangers. Thus, the suppression of the freezing of these droplets is very important.

Ice-covered ponds in the Untersee Oasis (East Antarctica): Distribution, chemical composition, and trajectory under a warming climate

open access: yesArctic, Antarctic, and Alpine Research, 2021
Climate change is impacting lakes and ponds in Antarctica. To that end, we investigated the distribution and chemical composition of ice-covered ponds in Untersee Oasis, East Antarctica.

Neurocircuit differences between memory traces of persistent hypoactivity and freezing following fear conditioning among the amygdala, hippocampus, and prefrontal cortex

open access: yesAIMS Neuroscience, 2021
We aimed to investigate the persistent trace of one traumatic event on neurocircuit controls in rats. Conditioning was reflected by reductions in rates of ‘freezing’ and ‘other-than-freezing’ motor activities, between which rats could alternate on ...

Breathing-driven prefrontal oscillations regulate maintenance of conditioned-fear evoked freezing independently of initiation

open access: yesNature Communications, 2021
Brain–body interactions are thought to be essential in emotions but their physiological basis remains poorly understood. In mice, regular 4 Hz breathing appears during freezing after cue-fear conditioning.

Effects of Different Treatments on the Structure and Physicochemical Properties of Artichoke Dietary Fiber

open access: yesShipin gongye ke-ji, 2022
The effects of two treatments–ultrafine grinding (UG) and freeze-ultrafine-grinding (FUG) on the structure and physicochemical properties of artichoke dietary fiber as dietary fiber (ADF) were investigated.
