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.

Algorithms, 2019 A generalization of Ding’s construction is proposed that employs as a defining set the collection of the sth powers ( s ≥ 2 ) of all nonzero elements in G F ( p m ) , where p ≥ 2 is prime.

Combinatorial Coding for Drosophila Neurons
PLoS Biology, 2007 One of the most intriguing questions in biology is how the many different types of cells in an organism can develop from a single cell, the fertilized egg. Nowhere is this question more pertinent than in the nervous system, where each neuron must be endowed with the correct receptors, neurotransmitters, and other crucial molecules to carry out its ...

Combinatorial construction of locally testable codes [PDF]
Proceedings of the fortieth annual ACM symposium on Theory of computing, 2008 An error correcting code is said to be locally testable if there is a test that checks whether a given string is a codeword, or rather far from the code, by reading only a constant number of symbols of the string. While the best known construction of locally testable codes (LTCs) by Ben-Sasson and Sudan [SIAM J. Comput., 38 (2008), pp.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Coded Caching based on Combinatorial Designs [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 We consider the standard broadcast setup with a single server broadcasting information to a number of clients, each of which contains local storage (called \textit{cache}) of some size, which can store some parts of the available files at the server.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

A survey and refinement of repairable threshold schemes
Journal of Mathematical Cryptology, 2018 We consider repairable threshold schemes (RTSs), which are threshold schemes that enable a player to securely reconstruct a lost share with help from their peers.

Key Distribution System Based on Hadamard Designs
Моделирование и анализ информационных систем, 2019 The problem of key distribution in a community for providing secure communication between its participants is studied. To solve this problem, key predistribution systems can be used, in which each user receives some key information that can later be used
