Continued fractions related to a group of linear fractional transformations

Open Mathematics, 2023
There are strong relations between the theory of continued fractions and groups of linear fractional transformations. We consider the group G3,3{G}_{3,3} generated by the linear fractional transformations a=1−1∕za=1-1/z and b=z+2b=z+2.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

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.

Transition from the harf theory to the syllabary theory in the Arabic linguistic tradition using the example of Ibrahim Anis’ description of the pausal form of a word

Вестник Самарского университета: История, педагогика, филология
The article deals with the issue of describing the pausal form of a word in the Arabic literary language, which existed within the framework of traditional grammar with its unique terminological base until the middle of the last century, and after it was

Brain’s functional network clustering coefficient changes in response to instruction (RTI) in students with and without reading disabilities: Multi-leveled reading brain’s RTI

Cogent Psychology, 2018
In students in grades 4 to 9 (22 males, 20 females), two reading disability groups—dyslexia (n = 20) or oral and written language learning disability (OWL LD) (n = 6)—were compared to each other and two kinds of control groups—typical readers (n = 6) or ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Что такое вид русского глагола? (теоретические модели описания русского вида)

Revue des études slaves, 2020
The article contains an overview of significantly different theoretical models of the Russian verb aspect: the “traditional” classifying category model (Russian Grammar 1980); the earlier inflectional category model (Karcevski, Isačenko, Maslov); the ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Reading stories in Arabic: the impact of lexico-phonological and diglossic distance level on comprehension and receptive and productive vocabulary among Arab kindergarten children

Frontiers in Education
PurposeThis study aims to investigate the impact of the lexico-phonological diglossic distance of story reading (a scaffolded storybook intervention, informed by Vygotsky’s theory of scaffolding and fading) on Arabic-speaking preschool children’s ...

Topological model of composite fermions in the cyclotron band generator picture: New insights

Results in Physics, 2018
A combinatorial group theory in the braid groups is correlated with the unusual “anyon” statistic of particles in 2D Hall system in the fractional quantum regime well.

Fox derivatives: a unique connection between group presentations and the integral group ring [PDF]

Advances in Group Theory and Applications, 2018
We give a criterion to determine whether generators can be removed from a finite presentation via Tietze transformations. We prove that for a generator in a pre- sentation ⟨X|R⟩ to be removable, there must exist a word in the normal closure of relators ...
