Stable commutator length in word-hyperbolic groups [PDF]
, 2009 In this paper we obtain uniform positive lower bounds on stable commutator length in word-hyperbolic groups and certain groups acting on hyperbolic spaces (namely the mapping class group acting on the complex of curves, and an amalgamated free product ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Monosyllabic focus verbs disrupt reading fluency in Mandarin: evidence from eye-tracking
Frontiers in Language SciencesFocus is a core component of information structure that highlights the most prominent element in a sentence. While pitch and duration are well-established prosodic markers of focus in Mandarin Chinese, the role of word length has received less attention.

(Un)Decidability Results for Word Equations with Length and Regular Expression Constraints [PDF]
, 2013 We prove several decidability and undecidability results for the satisfiability and validity problems for languages that can express solutions to word equations with length constraints.

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS 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 ...

When does length cause the word length effect? [PDF]
Journal of Experimental Psychology: Learning, Memory, and Cognition, 2011 The word length effect, the finding that lists of short words are better recalled than lists of long words, has been termed one of the benchmark findings that any theory of immediate memory must account for. Indeed, the effect led directly to the development of working memory and the phonological loop, and it is viewed as the best remaining evidence ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The \v Cerný conjecture for aperiodic automata [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 A word w is called a synchronizing (recurrent, reset, directable) word of a deterministic finite automaton (DFA) if w brings all states of the automaton to some specific state; a DFA that has a synchronizing word is said to be synchronizable.

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells
FEBS Open Bio, EarlyView.Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.
