A Submodule With Integrated Supercapacitors for HVDC-MMC Providing Fast Frequency Response

IEEE Transactions on Power Delivery, 2022
Modular multilevel converters (MMCs) have been recognized as the most attractive technology for high voltage direct current (HVDC) applications during the last years. Their advantages include the ability to freely control the internally stored energy in the distributed submodules (SMs) and to independently control AC and DC power. Recent studies showed

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 ...

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.

Simulation of dielectric frequency response of transformer insulation system [PDF]

, 2013
Frequency domain spectroscopy has been widely used to monitor the condition of insulation system in power transformers. For a core type of transformer, a simplified XY model of a duct has been developed which allows one to examine the contribution from ...

A Study of Frequency Specificity of the Auditory Fast Responses

AUDIOLOGY JAPAN, 1976
In order to establish the application of action potentials (AP) of the cochlear nerve and brain stem auditory evoked response (BSR) in clinical audiology, the frequency specificity of them was studied using the special masking techniques.The change of AP and BSR latencies and amplitudes of white noise evoked responses were observed using the high and ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

NEW WIDE-RANGE FAST-RESPONSE ANALOGUE MEASUREMENT OF FREQUENCY [PDF]

, 1985
A new high-performance analogue-type frequency/voltage (F/V) convertor is suggested. The proposed convertor shows good linearity and low ripple in a wide range from low to medium frequency. It has great simplicity and good dynamic response as fast as

Synergies between energy arbitrage and fast frequency response for battery energy storage systems [PDF]

, 2021
Energy storage can make key contributions to balancing future low-carbon energy systems by providing a variety of energy system services, with batteries expected to be widely deployed as costs fall with innovation.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
