Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Continuous Self-Similarity Breaking in Critical Collapse
, 1999 This paper studies near-critical evolution of the spherically symmetric scalar field configurations close to the continuously self-similar solution. Using analytic perturbative methods, it is shown that a generic growing perturbation departs from the ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

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 ...

SELF-SIMILARITY IN PITCH ORGANIZATION
Studia Universitatis Babeş-Bolyai. Musica, 2011 In this study we intend to discuss the self-similarity concept, which can be thought of as an organizing principle of the pitch of the sound. We will put emphasis on the self-similarity aspect of pitch organization in different series created by Anton ...

On a Segment Partition for Entropy Estimation
Моделирование и анализ информационных систем, 2020 Let \(Q_n\) be a partition of the interval \([0,1]\) defines as\(\begin{array}{l}Q_1 =\{0,q^2,q,1\}. \\Q_{n+1}' = qQ_n \cap q^2Q_n, \ \Q_{n+1}'' = q^2+qQ_n \cap qQ_n, \ \Q_{n+1}'''= q^2+qQ_n \cap q+q^2Q_n, \\Q_{n+1} = Q_{n+1}'\cup Q_{n+1}'' \cup Q_{n+1}

Coarse-graining and Self-similarity of Price Fluctuations
, 2001 We propose a new approach for analyzing price fluctuations in their strongly correlated regime ranging from minutes to months. This is done by employing a self-similarity assumption for the magnitude of coarse-grained price fluctuation or volatility. The
