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.

An optimization program based on the method of feasible directions: Theory and users guide [PDF]

open access: yes, 1994
The theory and user instructions for an optimization code based on the method of feasible directions are presented. The code was written for wide distribution and ease of attachment to other simulation software.

Decentralized Robust Energy Management of Multi-area Integrated Electricity-gas Systems

open access: yesJournal of Modern Power Systems and Clean Energy, 2021
This paper proposes a fast and decentralized solution methodology for the robust operation of multi-area integrated electricity-gas systems (M-IEGSs).

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS 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+.

Diversity and complexity in neural organoids

open access: yesFEBS 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.

Feasibility of a Novel Movement Preference Approach to Classify Case Complexity for Adults with Non-Specific Chronic Low Back Pain

open access: yesApplied Sciences
The non-specific nature of low back pain (LBP) poses challenges in its diagnosis and clinical management. Classifying case complexity with an exercise method may help overcome these challenges.

TWO TIME-SCALE FEASIBLE DIRECTION METHOD

open access: yesIFAC Proceedings Volumes, 2005
Abstract Stochastic constrained optimization problems with non-convex objective and convex feasible domain are considered for the case where the objective and constraint functions are available only throuth noisy observations. A general algorithm of the two time-scale stochastic approximation type is proposed for these problems.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
