ENHANCING STABILITY AND REGULATION OF OUTPUT VOLTAGE IN BOOST CONVERTERS WITH LEARNING SLIDING MODE CONTROL

open access: yesMağallaẗ Al-kūfaẗ Al-handasiyyaẗ
Although DC to DC convertors might be considered as the most widely used circuits in power electronic, where a specific DC output voltage must be stabilized to a specific desired level, yet theses circuits unfortunately exhibit a nonlinear behavior.

A novel high‐efficient step‐up converter with continuous input current, common ground, and minimum stress on semiconductors

open access: yesIET Power Electronics, 2023
This study proposes a comprehensive analysis of a novel non‐isolated step‐up converter with continuous input current and common ground. The proposed topology provides high voltage gain besides insignificant voltage and current stress across switches and ...

Novel bidirectional universal 1‐phase/3‐phase‐input unity power factor differential AC/DC converter

open access: yesElectronics Letters, 2023
A common 400 V dc bus for industrial motor drives advantageously allows the use of high‐performance 600 V power semiconductor technology in the inverter drive converter stages and to lower the rated power of the supplying rectifier system.

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

open access: yesFEBS 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

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

open access: yesFEBS 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.

Control of Dual-Opposed Stirling Convertors with Active Power Factor Correction Controllers [PDF]

open access: yes, 2006
When using recently-developed active power factor correction (APFC) controllers in power systems comprised of dual-opposed free-piston Stirling convertors, a variety of configurations of the convertors and controller(s) can be considered, with ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
