Reactor behavior comparisons for two liquid metal-cooled fast reactors during an event of loss of coolant

Case Studies in Thermal Engineering, 2019
The aim of this paper is to present a fast-numerical tool based on the average channel approach to analyze the response of fast reactors under unprotected loss of flow events.

The contrasting response of outlet glaciers to interior and ocean forcing [PDF]

The Cryosphere, 2020
The dynamics of marine-terminating outlet glaciers are of fundamental interest in glaciology and affect mass loss from ice sheets in a warming climate. In this study, we analyze the response of outlet glaciers to different sources of climate forcing.

A very fast control based on hysteresis of the Cout current with a frequency loop to operate at constant frequency [PDF]

, 2009
The combination of non-linear control and linear control proposed in [1] provides very fast transient response (voltage step from 1 V to 1.5 V in 2 μs). This non-linear control is based on hysteretic control of the Cout current.

Research on transient AC overvoltage suppression method of DC sending end based on novel fast-excitation MCR

International Journal of Electrical Power & Energy Systems
The growing reliance on high-power high-voltage direct current (HVDC) transmission systems has intensified challenges associated with transient AC overvoltage induced by commutation failures resulting from converter operation characteristics.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Fast excitation structure for improving the transient time of magnetic controlled reactors

International Journal of Electrical Power & Energy Systems
With the increasing proportion of renewable energy usage, the randomness and volatility of renewable energy have led to a corresponding increase in the demand for reactive power regulation in the power system.

Transient absorption and photocurrent microscopy show hot electron supercollisions describe the rate-limiting relaxation step in graphene

, 2013
Using transient absorption (TA) microscopy as a hot electron thermometer we show disorder-assisted acoustic-phonon supercollisions (SCs) best describes the rate-limiting relaxation step in graphene over a wide range of lattice temperatures ($T_l=$5-300 K)

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Numerical study on temperature response of microheater and evolution characteristics of superheated zone under fast transient heating

Case Studies in Thermal Engineering
The nucleate boiling process that occurs on the surface of a microheater immersed in a liquid pool under fast transient heating conditions can be regarded as homogeneous or near-homogeneous nucleation, exhibiting a significant difference when compared to
