Upregulation of FOXM1 induces genomic instability in human epidermal keratinocytes [PDF]

, 2010
Background The human cell cycle transcription factor FOXM1 is known to play a key role in regulating timely mitotic progression and accurate chromosomal segregation during cell division.

OSCILLATORY INSTABILITY

Problems of Atomic Science and Technology, 2019
The dynamics of the oscillator system is investigated. The conditions under which this dynamics becomes unstable are determined. In particular, it is shown that plasma in constant magnetic field becomes unstable if its density exceeds a certain critical value. In this case, instability develope (oscillatory instability).

Automatic P-wave arrival picking for microseismic signals of mines using a hybrid neural network with constrained attention and CNN-BiLSTM

Journal of Rock Mechanics and Geotechnical Engineering
Microseismic (MS) monitoring is a critical technology for ground pressure control, water inrush warning, and slope stability management in mining, as outlined by national standards and industry regulations.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]

, 2005
We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

On the instability of competitive equilibrium: a further example [PDF]

It is shown that a Walrasian price adjustment process fails to converge to an equilibrium in an exchange economy with three consumers and three commodities, where each consumer has a quasilinear utility function, desires only two commodities, and demands

Does VAT reduce the instability of tax revenues? [PDF]

In this study, we examine whether or not the adoption of value-added tax (VAT) in developing countries is an effective way of stabilising tax revenues.

Threonine 348 regulates the subcellular localization of PTEN

FEBS Open Bio, EarlyView.
Thr348 in the C2 domain is a key contributor to PTEN subcellular localization. The PTEN350 fragment and PTENA4 accumulated in the nucleus, whereas PTENK13R,A4 predominantly localized to the plasma membrane. In contrast, substitution of Thr348 with Asp (T348D) disrupted these characteristic localization patterns, resulting in predominant cytoplasmic ...
