Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Elementary Fractal Geometry 7: An Algorithm Visualizing the Magnification Flow
Fractal and FractionalSelf-similar sets are defined as compact attractors. Their interior structure, however, is revealed only by successive magnification. This requires the use of a computer.

Existence of an Unbiased Entropy Estimator for the Special Bernoulli Measure
Моделирование и анализ информационных систем, 2017 Let \(\Omega = A^{N}\) be a space of right-sided infinite sequences drawn from a finite alphabet \(A = \{0,1\}\), \(N = \{1,2,\dots \}\), \[\label{rho} \rho(\boldsymbol{x},\boldsymbol{y}) = \sum_{k=1}^{\infty}|x_{k} - y_{k}|2^{-k} \] a metric on ...

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.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Self similar solutions of generalized Burgers equation
Electronic Journal of Differential Equations, 2005 In this paper, we study the initial-value problem $$displaylines{ (|u'|^{p-2}u')'+eta r u'+alpha u-gamma |u|^{q-1}u|u'|^{p-2}u'=0, quad r greater than 0, cr u(0)=A,quad u'(0)=0, }$$ where $A$ greater than 0, $p$ greater than 2, $q greater than 1, $alpha ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Limits of Predictability of a Global Self-Similar Routing Model in a Local Self-Similar Environment
Atmosphere, 2020 Regional Distributed Hydrological models are being adopted around the world for prediction of streamflow fluctuations and floods. However, the details of the hydraulic geometry of the channels in the river network (cross sectional geometry, slope, drag ...

Self-similar chain conformations in polymer gels
, 1999 We use molecular dynamics simulations to study the swelling of randomly end-cross-linked polymer networks in good solvent conditions. We find that the equilibrium degree of swelling saturates at Q_eq = N_e**(3/5) for mean strand lengths N_s exceeding the
