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.

Advances in Electrical and Computer Engineering, 2018 Reactive power demanded by many loads besides active power is one of the important issue in terms of the efficient use of energy. The optimal solution of reactive power demand can be performed by tuning the excitation current of synchronous motor ...

Large direct drive generators: the induction machine as an alternative to permanent magnet machines
The Journal of Engineering, 2019 Design of direct drive power take off in renewable energy generators tends to focus on force density, naturally leading to the use of relatively expensive permanent magnet machines.

Triangle-factors in powers of graphs
Electronic Notes in Discrete Mathematics, 2003 Abstract In this paper, we investigate existence of triangle-factors, that is 2-factors in which every cycle is of length 3, in powers of graphs of order 3 k , k ≥ 1. It is easy to show that G 4 contains a triangle-factor for any connected graph and G 3 contains a triangle-factor for any connected claw-free graph G Our main result is that G

, 2021 A novel single-switch single-stage high power factor LED driver is proposed by integrating a flyback converter, a buck–boost converter and a current balance circuit. Only an active switch and a corresponding control circuit are used. The LED power can be

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Quantum Effects in the Thermoelectric Power Factor of Low-Dimensional Semiconductors. [PDF]
Physical Review Letters, 2016 We theoretically investigate the interplay between the confinement length L and the thermal de Broglie wavelength Λ to optimize the thermoelectric power factor of semiconducting materials.

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