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.

Multiple positive solutions to some second-order integral boundary value problems with singularity on space variable

Boundary Value Problems, 2017
This article deals with integral boundary value problems of the second-order differential equations { u ″ ( t ) + a ( t ) u ′ ( t ) + b ( t ) u ( t ) + f ( t , u ( t ) ) = 0 , t ∈ J + , u ( 0 ) = ∫ 0 1 g ( s ) u ( s ) d s , u ( 1 ) = ∫ 0 1 h ( s ) u ( s )

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

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 ...

“The World, More or Less” by Jean Rouaud: between novel and autofiction

RUDN Journal of Studies in Literature and Journalism, 2019
This article discusses theoretical approaches to autofiction - a new form of self-writing which spread in French literature from the 80s. The analysis of the autofictional device implemented in the novel “The World, More or Less” by Jean Rouaud produces ...

Plans for the electron cyclotron heating system on J-TEXT [PDF]

EPJ Web of Conferences, 2019
A new 105 GHz/500 kW/1 s electron cyclotron resonance heating (ECRH) system has been designed and being constructed on J-TEXT Tokamak. This system mainly consists of a microwave source, a transmission line, a launcher and other auxiliary units.

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.

Impact of straight slot impingement jets on heat transfer enhancement of TiO2/H2O nanofluid flow in a square channel: CFD analysis

Scientific Reports
This study presents a computational fluid dynamics (CFD) analysis of heat transfer and pressure drop in a straight slot impingement jet, utilizing $$\:\text{T}\text{i}{\text{O}}_{2}/{\text{H}}_{2}\text{O}$$ nanofluid within a square duct.
