Differentiating Diffuse Aurora
, 2019 Pulsating aurora is a pervasive early morning auroral display. Perhaps because of the awkward viewing hours, it received comparatively little attention in past years and is often discussed as if it is just one phenomenon. However, pulsating aurora can be differentiated into at least three types based on the extent of their pulsation and structuring ...

DIFFUSIBLE FACTORS AND CELL DIFFERENTIATION [PDF]
Pediatric Research, 1993 All adult organs consist of several different cell-types; these first appear in embryos, and are then maintained, and usually replenished from stem cells, in later life. In humans and in vertebrate animals, interactions between cells are of overwhelming importance in initiating (and maintaining) cell differentiation.

Circulation-controlled firewhirls with differential diffusion
, 2018 A flame-sheet theory for circulation-controlled firewhirls with differential diffusion is presented to investigate the effects of non-unity and unequal Lewis numbers on the flame shape and height of the firewhirls.

FEBS Open Bio, EarlyView.Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Deterministic homogenization for fast-slow systems with chaotic noise [PDF]
, 2014 Consider a fast-slow system of ordinary differential equations of the form $\dot x=a(x,y)+\varepsilon^{-1}b(x,y)$, $\dot y=\varepsilon^{-2}g(y)$, where it is assumed that $b$ averages to zero under the fast flow generated by $g$. We give conditions under

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
