Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Urbani obvodni javni prostor – reka kot razvojni generator : Urban riverside public space – river as the generator of development [PDF]

open access: yesGeodetski Vestnik, 2012
Odprti javni prostori imajo ključno vlogo v razpoznavnosti mest, kar zlasti velja za javne prostore, ki leže ob rekah. Zato so reke, ki tečejo skozi mesta, njihovo naravno bogastvo in hkrati velik razvojni potencial. So močan ekonomski razvojni generator

Smallest Squared Squares

open access: yes, 2013
In this paper we have a look at squared squares with small integer sidelengths, where the only restriction is that any two subsquares of the same size are not allowed to share a full border. We prove that there are exactly two such squared squares (and their mirrored versions) up to and including size 17x17. They are shown in Figure 1 (page 2).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Chiral Compactification on a Square

open access: yes, 2004
We study quantum field theory in six dimensions with two of them compactified on a square. A simple boundary condition is the identification of two pairs of adjacent sides of the square such that the values of a field at two identified points differ by ...

Dynamic squares

open access: yesJournal of Philosophical Logic, 1995
The authors provide various propositional logics for the dynamic implication studied by Kamp, Groenendijk, Stokhof, and others to analyse some natural language phenomena. The underlying idea in these theories, which analyses sentence meanings as active entities transforming state spaces like computer programs, is abstracted in the framework of two ...

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.
