Multistage Zeeman deceleration of metastable neon
, 2011 A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator.

Rapamycin decelerates cellular senescence [PDF]
Cell Cycle, 2009 When the cell cycle is arrested but cellular growth is not, then cells senesce, permanently losing proliferative potential. Here we demonstrated that the duration of cell cycle arrest determines a progressive loss of proliferative capacity. In human and rodent cell lines, rapamycin (an inhibitor of mTOR) dramatically decelerated loss of proliferative ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

How do Today's Modern Passenger Cars Brake?
Logi, 2018 The article deals with issues of vehicle braking from different points of view. We made repeated braking tests of modern vehicles during intensive braking on various asphalt surfaces with the goal to evaluate character of this random variable.

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 newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Estimation of car braking parameters
Lietuvos Matematikos Rinkinys, 2004 In the paper the problem of prediction of car braking distance from its initial speed is considered. Based on the data of braking experiments, a regression model is fitted and validated and the covariance structure of the prediction errors is ...

A simple toy model of the advective-acoustic instability I. Perturbative approach
, 2008 Some general properties of the advective-acoustic instability are described and understood using a toy model which is simple enough to allow for analytical estimates of the eigenfrequencies.
