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.

Recent Development of Frequency Estimation Methods for Future Smart Grid
IEEE Open Access Journal of Power and Energy, 2020 The frequency estimated by the Phasor Measurement Unit (PMU) is a critical index of power system status and supports many smart grid applications. The future smart grid features high penetration of renewables and more fast-moving power electronics ...

Estimating stationary mass, frequency by frequency
CoRRSuppose we observe a trajectory of length $n$ from an exponentially $α$-mixing stochastic process over a finite but potentially large state space. We consider the problem of estimating the probability mass placed by the stationary distribution of any such process on elements that occur with a certain frequency in the observed sequence. We estimate this

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Making better use of local data in flood frequency estimation [PDF]
, 2017 Flood frequency estimates are an essential part of flood risk management. Methods described in the Flood Estimation Handbook (FEH) published in 1999, and many subsequent updates, are the industry standard for flood frequency estimation in the UK. Even

Frequency-Locked Loop Based on a Repetitive Controller for Grid Synchronization Systems
IEEE Access, 2020 The frequency-locked loop based on a second-order generalized integrator has been widely used in grid synchronization systems but featuring unfavorable harmonics filtering performance. To solve this issue, a frequency-locked loop based on multiple second-

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Joint channel estimation and multi-user detection for SDMA/OFDM based on dual repeated weighted boosting search [PDF]
, 2011 A joint channel estimation and Multi-User Detection (MUD) scheme is proposed for multi-user Multiple-Input Multiple-Output (MIMO) Space Division Multiple Access / Orthogonal Frequency-Division Multiplexing (SDMA/OFDM) systems.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
