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.

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.

fEEG contrast enhancement: power law transformation vs intuitionistic fuzzy set

open access: yes, 2020
This work focused on contrast enhancement of Flat Electroencephalography (fEEG) image by using Power Law Transformation (PLT) and Intuitionistic Fuzzy Set (IFS). PLT is a classical method whereas the IFS is an advanced fuzzy approach.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Pandiagonal Magic Square Reconfiguration of Partially Shaded Photovoltaic Arrays for Simplified MPPT and Power Enhancement

open access: yesIEEE Access
Partial shading remains a critical challenge in photovoltaic (PV) systems, causing power losses, current mismatch, and multiple peaks in the power-voltage (P-V) characteristics, thereby reducing overall energy yield.

Improve the quality of 1060Al/Q235 explosive composite plate by friction stir processing

open access: yesJournal of Materials Research and Technology, 2020
The common aluminum/steel composite plates made by explosive welding often have steel cuttings, holes, cracks and other defects at the interface, which make the component premature failure.
